Security: * Moderate. CVE-2024-25629. Reading malformatted `/etc/resolv.conf`, `/etc/nsswitch.conf` or the `HOSTALIASES` file could result in a crash. [GHSA-mg26-v6qh-x48q](https://github.com/c-ares/c-ares/security/advisories/GHSA-mg26-v6qh-x48q) Features: * New function `ares_queue_active_queries()` to retrieve number of in-flight queries. [PR #712](https://github.com/c-ares/c-ares/pull/712) * New function `ares_queue_wait_empty()` to wait for the number of in-flight queries to reach zero. [PR #710](https://github.com/c-ares/c-ares/pull/710) * New `ARES_FLAG_NO_DEFLT_SVR` for `ares_init_options()` to return a failure if no DNS servers can be found rather than attempting to use `127.0.0.1`. This also introduces a new ares status code of `ARES_ENOSERVER`. [PR #713](https://github.com/c-ares/c-ares/pull/713) Changes: * EDNS Packet size should be 1232 as per DNS Flag Day. [PR #705](https://github.com/c-ares/c-ares/pull/705) Bugfixes: * Windows DNS suffix search list memory leak. [PR #711](https://github.com/c-ares/c-ares/pull/711) * Fix warning due to ignoring return code of `write()`. [PR #709](https://github.com/c-ares/c-ares/pull/709) * CMake: don't override target output locations if not top-level. [Issue #708](https://github.com/c-ares/c-ares/issues/708) * Fix building c-ares without thread support. [PR #700](https://github.com/c-ares/c-ares/pull/700) Thanks go to these friendly people for their efforts and contributions for this release: * Anthony Alayo (@anthonyalayo) * Brad House (@bradh352) * Cheng Zhao (@zcbenz) * Cristian Rodríguez (@crrodriguez) * Daniel Stenberg (@bagder) * Oliver Welsh (@oliverwelsh) * Vojtěch Vobr (@vojtechvobr) c-ares-1.27.0/compile0000755000175000017500000001635014537541751010033 #! /bin/sh # Wrapper for compilers which do not understand '-c -o'. scriptversion=2018-03-07.03; # UTC # Copyright (C) 1999-2021 Free Software Foundation, Inc. # Written by Tom Tromey . # # This program is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2, or (at your option) # any later version. # # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Additionally * this file is also included and used when building the library. * * If compilation fails on this file it is certainly sure that the * problem is elsewhere. It could be a problem in the ares_build.h * header file, or simply that you are using different compilation * settings than those used to build the library. * * Nothing in this file is intended to be modified or adjusted by the * c-ares library user nor by the c-ares library builder. * * Do not deactivate any check, these are done to make sure that the * library is properly built and used. * * You can find further help on the c-ares development mailing list: * http://lists.haxx.se/listinfo/c-ares/ * * NOTE 2 * ------ * * Some of the following compile time checks are based on the fact * that the dimension of a constant array can not be a negative one. * In this way if the compile time verification fails, the compilation * will fail issuing an error. The error description wording is compiler * dependent but it will be quite similar to one of the following: * * "negative subscript or subscript is too large" * "array must have at least one element" * "-1 is an illegal array size" * "size of array is negative" * * If you are building an application which tries to use an already * built c-ares library and you are getting this kind of errors on * this file, it is a clear indication that there is a mismatch between * how the library was built and how you are trying to use it for your * application.

Change to c-ares source folder where Makefile.msvc file is located and run: > nmake -f Makefile.msvc This will build all c-ares libraries as well as three sample programs. Once the above command has finished a new folder named MSVCXX will exist below the folder where makefile.msvc is found. The name of the folder depends on the MSVC compiler version being used to build c-ares. Below the MSVCXX folder there will exist four folders named 'cares', 'ahost', and 'adig'. The 'cares' folder is the one that holds the c-ares libraries you have just generated, the other three hold sample programs that use the libraries. The above command builds four versions of the c-ares library, dynamic and static versions and each one in release and debug flavours. Each of these is found in folders named dll-release, dll-debug, lib-release, and lib-debug, which hang from the 'cares' folder mentioned above. Each sample program also has folders with the same names to reflect which library version it is using. How to install using MSVC from the command line ----------------------------------------------- In order to allow easy usage of c-ares libraries it may be convenient to install c-ares libraries and header files to a common subdirectory tree. Once that c-ares libraries have been built using procedure described above, use same command prompt window to define environment variable INSTALL_DIR to designate the top subdirectory where installation of c-ares libraries and header files will be done. > set INSTALL_DIR=c:\c-ares Afterwards, run following command to actually perform the installation: > nmake -f Makefile.msvc install Installation procedure will copy c-ares libraries to subdirectory 'lib' and c-ares header files to subdirectory 'include' below the INSTALL_DIR subdir. When environment variable INSTALL_DIR is not defined, installation is done to c-ares source folder where Makefile.msvc file is located. Relationship between c-ares library file names and versions ----------------------------------------------------------- c-ares static release library version files: libcares.lib -> static release library c-ares static debug library version files: libcaresd.lib -> static debug library c-ares dynamic release library version files: cares.dll -> dynamic release library cares.lib -> import library for the dynamic release library cares.exp -> export file for the dynamic release library c-ares dynamic debug library version files: caresd.dll -> dynamic debug library caresd.lib -> import library for the dynamic debug library caresd.exp -> export file for the dynamic debug library caresd.pdb -> debug symbol file for the dynamic debug library How to use c-ares static libraries ---------------------------------- When using the c-ares static library in your program, you will have to define preprocessor symbol CARES_STATICLIB while building your program, otherwise you will get errors at linkage stage.

Each row is an IP address followed by * a list of space delimited hostnames that match the ip address. This is used * for both forward and reverse lookups. * * We are caching the entire parsed hosts file for performance reasons. Some * files may be quite sizable and as per Issue #458 can approach 1/2MB in size, * and the parse overhead on a rapid succession of queries can be quite large. * The entries are stored in forwards and backwards hashtables so we can get * O(1) performance on lookup. The file is cached until the file modification * timestamp changes. * * The hosts file processing is quite unique. It has to merge all related hosts * and ips into a single entry due to file formatting requirements. For * instance take the below: * * 127.0.0.1 localhost.localdomain localhost * ::1 localhost.localdomain localhost * 192.168.1.1 host.example.com host * 192.168.1.5 host.example.com host * 2620:1234::1 host.example.com host6.example.com host6 host * * This will yield 2 entries. * 1) ips: 127.0.0.1,::1 * hosts: localhost.localdomain,localhost * 2) ips: 192.168.1.1,192.168.1.5,2620:1234::1 * hosts: host.example.com,host,host6.example.com,host6 * * It could be argued that if searching for 192.168.1.1 that the 'host6' * hostnames should not be returned, but this implementation will return them * since they are related.

The Ancillary Function Driver (AFD) is the low level * implementation that Winsock2 sits on top of. Winsock2 unfortunately does * not expose the equivalent of epoll() or kqueue(), but it is possible to * access AFD directly and use along with IOCP to simulate the functionality. * We want to use IOCP if possible as it gives us the ability to monitor more * than just sockets (WSAPoll is not an option), and perform arbitrary callbacks * which means we can hook in non-socket related events. * * The information for this implementation was gathered from "wepoll" and * "libuv" which both use slight variants on this, but this implementation * doesn't directly follow either methodology. * * Initialization: * 1. Dynamically load the NtDeviceIoControlFile and NtCancelIoFileEx internal * symbols from ntdll.dll. These functions are used to submit the AFD POLL * request and to cancel a prior request, respectively. * 2. Create an IO Completion Port base handle via CreateIoCompletionPort() * that all socket events will be delivered through. * 3. Create a callback to be used to be able to interrupt waiting for IOCP * events, this may be called for allowing enqueuing of additional socket * events or removing socket events. PostQueuedCompletionStatus() is the * obvious choice. Use the same container structure as used with a Socket * but tagged indicating it is not as the CompletionKey (important!). * * Socket Add: * 1. Create/Allocate a container for holding metadata about a socket: * - SOCKET base_socket; * - SOCKET peer_socket; * - OVERLAPPED overlapped; -- Used by AFD POLL * - AFD_POLL_INFO afd_poll_info; -- Used by AFD POLL * 2. Call WSAIoctl(..., SIO_BASE_HANDLE, ...) to unwrap the SOCKET and get * the "base socket" we can use for polling. It appears this may fail so * we should call WSAIoctl(..., SIO_BSP_HANDLE_POLL, ...) as a fallback. * 3. The SOCKET handle we have is most likely not capable of supporting * OVERLAPPED, and we need to have a way to unbind a socket from IOCP * (which is done via a simple closesocket()) so we need to duplicate the * "base socket" using WSADuplicateSocketW() followed by * WSASocketW(..., WSA_FLAG_OVERLAPPED) to create this "peer socket" for * submitting AFD POLL requests. * 4. Bind to IOCP using CreateIoCompletionPort() referencing the "peer * socket" and the base IOCP handle from "Initialization". Use the * pointer to the socket container as the "CompletionKey" which will be * returned when an event occurs. * 5. Submit AFD POLL request (see "AFD POLL Request" section) * * Socket Delete: * 1. Call "AFD Poll Cancel" (see Section of same name) * 2. If a cancel was requested (not bypassed due to no events, etc), tag the * "container" for the socket as pending delete, and when the next IOCP * event for the socket is dequeued, cleanup. * 3. Otherwise, call closesocket(peer_socket) then free() the container * which will officially delete it. * NOTE: Deferring delete may be completely unnecessary. In theory closing * the peer_socket() should guarantee no additional events will be * delivered. But maybe if there's a pending event that hasn't been * read yet but already trigggered it would be an issue, so this is * "safer" unless we can prove its not necessary. * * Socket Modify: * 1. Call "AFD Poll Cancel" (see Section of same name) * 2. If a cancel was not enqueued because there is no pending request, * submit AFD POLL request (see "AFD POLL Request" section), otherwise * defer until next socket event. * * Event Wait: * 1. Call GetQueuedCompletionStatusEx() with the base IOCP handle, a * stack allocated array of OVERLAPPED_ENTRY's, and an appropriate * timeout. * 2. Iterate across returned events, the CompletionKey is a pointer to the * container registered with CreateIoCompletionPort() or * PostQueuedCompletionStatus() * 3. If object indicates it is pending delete, go ahead and * closesocket(peer_socket) and free() the container. Go to the next event. * 4. Submit AFD POLL Request (see "AFD POLL Request"). We must re-enable * the request each time we receive a response, it is not persistent. * 5. Notify of any events received as indicated in the AFD_POLL_INFO * Handles[0].Events (NOTE: check NumberOfHandles first, make sure it is * > 0, otherwise we might not have events such as if our last request * was cancelled). * * AFD Poll Request: * 1. Initialize the AFD_POLL_INFO structure: * Exclusive = TRUE; // Auto cancel duplicates for same socket * NumberOfHandles = 1; * Timeout.QuadPart = LLONG_MAX; * Handles[0].Handle = (HANDLE)base_socket; * Handles[0].Status = 0; * Handles[0].Events = ... set as appropriate AFD_POLL_RECEIVE, etc; * 2. Zero out the OVERLAPPED structure * 3. Create an IO_STATUS_BLOCK pointer (iosb) and set it to the address of * the OVERLAPPED "Internal" member. * 4. Set the "Status" member of IO_STATUS_BLOCK to STATUS_PENDING * 5. Call * NtDeviceIoControlFile((HANDLE)peer_socket, NULL, NULL, &overlapped, * iosb, IOCTL_AFD_POLL * &afd_poll_info, sizeof(afd_poll_info), * &afd_poll_info, sizeof(afd_poll_info)); * NOTE: Its not clear to me if the IO_STATUS_BLOCK pointing to OVERLAPPED * is for efficiency or if its a requirement for AFD. This is what * libuv does, so I'm doing it here too. * * AFD Poll Cancel: * 1. Check to see if the IO_STATUS_BLOCK "Status" member for the socket * is still STATUS_PENDING, if not, no cancel request is necessary. * 2. Call * NtCancelIoFileEx((HANDLE)peer_socket, iosb, &temp_iosb); * * * References: * - https://github.com/piscisaureus/wepoll/ * - https://github.com/libuv/libuv/ */ typedef struct { /* Dynamically loaded symbols */ NtDeviceIoControlFile_t NtDeviceIoControlFile; NtCancelIoFileEx_t NtCancelIoFileEx; /* Implementation details */ HANDLE iocp_handle; } ares_evsys_win32_t; typedef struct { /*!

See \fIares_create_query(3)\fP instead! The .B ares_mkquery function composes a DNS query with a single question. The parameter .I name gives the query name as a NUL-terminated C string of period-separated labels optionally ending with a period; periods and backslashes within a label must be escaped with a backlash. The parameters .I dnsclass and .I type give the class and type of the query using the values defined in .BR . The parameter .I id gives a 16-bit identifier for the query. The parameter .I rd should be nonzero if recursion is desired, zero if not. The query will be placed in an allocated buffer, a pointer to which will be stored in the variable pointed to by .IR buf , and the length of which will be stored in the variable pointed to by .IR buflen . It is the caller's responsibility to free this buffer using \fIares_free_string(3)\fP when it is no longer needed. Usage of \fIares_mkquery(3)\fP is deprecated, whereas the function is equivalent to \fIares_create_query(3)\fP with \fBmax_udp_size\fP set to 0. .SH RETURN VALUES .B ares_mkquery can return any of the following values: .TP 15 .B ARES_SUCCESS Construction of the DNS query succeeded. .TP 15 .B ARES_ENOTFOUND The query name .I name refers to a .I .onion domain name.

The function is a combination of \fIares_gethostbyaddr(3)\fP and \fIgetservbyport(3)\fP. The function will translate the address either by executing a host query on the name service channel identified by .IR channel or it will attempt to resolve it locally if possible. The parameters .I sa and .I len give the address as a sockaddr structure, and .I flags gives the options that the function will use. Valid flags are listed below: .TP 19 .B ARES_NI_NOFQDN Only the nodename portion of the FQDN is returned for local hosts. .TP 19 .B ARES_NI_NUMERICHOST The numeric form of the hostname is returned rather than the name. .TP 19 .B ARES_NI_NAMEREQD An error is returned if the hostname cannot be found in the DNS. .TP 19 .B ARES_NI_NUMERICSERV The numeric form of the service is returned rather than the name. .TP 19 .B ARES_NI_TCP The service name is to be looked up for the TCP protocol. .TP 19 .B ARES_NI_UDP The service name is to be looked up for the UDP protocol. .TP 19 .B ARES_NI_SCTP The service name is to be looked up for the SCTP protocol. .TP 19 .B ARES_NI_DCCP The service name is to be looked up for the DCCP protocol. .TP 19 .B ARES_NI_NUMERICSCOPE The numeric form of the scope ID is returned rather than the name. .TP 19 .B ARES_NI_LOOKUPHOST A hostname lookup is being requested. .TP 19 .B ARES_NI_LOOKUPSERVICE A service name lookup is being requested. .PP When the query is complete or has failed, the ares library will invoke \fIcallback\fP. Completion or failure of the query may happen immediately, or may happen during a later call to \fIares_process(3)\fP, \fIares_destroy(3)\fP or \fIares_cancel(3)\fP. .PP When the associated callback is called, it is called with a channel lock so care must be taken to ensure any processing is minimal to prevent DNS channel stalls. The callback may be triggered from a different thread than the one which called \fIares_getnameinfo(3)\fP. For integrators running their own event loops and not using \fBARES_OPT_EVENT_THREAD\fP, care needs to be taken to ensure any file descriptor lists are updated immediately within the eventloop when notified. .PP The callback argument .I arg is copied from the .B ares_getnameinfo argument .IR arg . The callback argument .I status indicates whether the query succeeded and, if not, how it failed.

The \fIares_dns_parse(3)\fP function parses the buffer provided in .IR buf with length provided in .IR buf_len. The .IR flags parameter can be one or more \fIares_dns_parse_flags_t\fP, or zero if no flags are needed. The resulting dns record data structure is stored into the variable pointed to by .IR dnsrec and must be destroyed using \fIares_dns_record_destroy(3)\fP. The \fIares_dns_write(3)\fP function takes a populated DNS record structure in .IR dnsrec and writes a wire-format DNS message into the variable pointed to by .IR buf and writes the length of the buffer into the variable pointed to by .IR buf_len. The buffer must be destroyed using \fIares_free_string(3)\fP. The \fIares_dns_record_create(3)\fP function creates an empty DNS record structure in the variable pointed to by .IR dnsrec. The .IR id parameter is the DNS message id, however if passing to \fIares_send(3)\fP this identifier will be overwritten, so should typically be 0. The .IR flags parameter is one or more \fIares_dns_flags_t\fP. The opcode is passed in the .IR opcode parameter and should typically be \fIARES_OPCODE_QUERY\fP. The response code is meant mostly for responses and is passed in the .IR rcode parameter and is typically \fPARES_RCODE_NOERROR\fP. The \fIares_dns_record_get_id(3)\fP function is used to retrieve the DNS message id from the DNS record provided in the .IR dnsrec parameter. The \fIares_dns_record_get_flags(3)\fP function is used to retrieve the DNS message flags from the DNS record provided in the .IR dnsrec parameter. The \fIares_dns_record_get_opcode(3)\fP function is used to retrieve the DNS message flags from the DNS record provided in the .IR dnsrec parameter. The \fIares_dns_record_get_rcode(3)\fP function is used to retrieve the DNS message response code from the DNS record provided in the .IR dnsrec parameter. The \fIares_dns_record_query_add(3)\fP function is used to add a question to the DNS record provided in the .IR dnsrec parameter. The domain name specified for the question is provided in the .IR name parameter, along with the question type in the .IR qtype parameter and the question class (typically \fIARES_CLASS_IN\fP) in the .IR qclass parameter. The \fIares_dns_record_query_cnt(3)\fP function is used to retrieve the number of DNS questions in the DNS record provided in the .IR dnsrec parameter. The \fIares_dns_record_query_get(3)\fP function is used to retrieve the details of a single DNS question in the provided .IR dnsrec parameter. The index provided in the .IR idx parameter must be less than the value returned from \fIares_dns_record_query_cnt(3)\fP. The DNS question name will be returned in the variable pointed to by the .IR name parameter, this may be provided as NULL if the name is not needed. The DNS question type will be returned in the variable pointed to by the .IR qtype parameter, this may be provided as NULL if the type is not needed. The DNS question class will be returned in the variable pointed to by the .IR qclass parameter, this may be provided as NULL if the class is not needed. .SH RETURN VALUES \fIares_dns_parse(3)\fP, \fIares_dns_write(3)\fP, \fIares_dns_record_create(3)\fP, \fIares_dns_record_query_add(3)\fP, and \fIares_dns_record_query_get(3)\fP all return an \fIares_status_t\fP error code. .B ARES_SUCCESS is returned on success, .B ARES_ENOMEM is returned on out of memory, .B ARES_EFORMERR is returned on misuse. \fIares_dns_record_get_id(3)\fP, \fIares_dns_record_get_flags(3)\fP, \fIares_dns_record_get_opcode(3)\fP, \fIares_dns_record_get_rcode(3)\fP, and \fIares_dns_record_query_cnt(3)\fP all returned their prescribed datatype values and in general can't fail except for misuse cases, in which a 0 may be returned, however 0 can also be a valid return value for most of these functions. .SH AVAILABILITY These functions were first introduced in c-ares version 1.22.0. .SH SEE ALSO .BR ares_dns_mapping (3), .BR ares_dns_rr (3), .BR ares_free_string (3) .SH AUTHOR Copyright (C) 2023 The c-ares project and its members. c-ares-1.27.0/docs/ares_dns_opt_get_datatype.30000644000175000017500000000014314530123235014656 .\" .\" Copyright (C) Daniel Stenberg .\" SPDX-License-Identifier: MIT .so man3/ares_dns_mapping.3 c-ares-1.27.0/docs/ares_parse_mx_reply.30000644000175000017500000000303514566043726013531 .\" .\" Copyright 1998 by the Massachusetts Institute of Technology. .\" SPDX-License-Identifier: MIT .\" .TH ARES_PARSE_MX_REPLY 3 "4 August 2009" .SH NAME ares_parse_mx_reply \- Parse a reply to a DNS query of type MX .SH SYNOPSIS #include int ares_parse_mx_reply(const unsigned char* \fIabuf\fP, int \fIalen\fP, struct ares_mx_reply** \fImx_out\fP); .fi .SH DESCRIPTION The .B ares_parse_mx_reply function parses the response to a query of type MX into a linked list of .I struct ares_mx_reply The parameters .I abuf and .I alen give the contents of the response.

This can take place anytime after \fIares_library_init(3)\fP. It must take place after \fIares_library_init_jvm\fP. ares_library_init_android must be called before DNS resolution will work on Android 8 (Oreo) or newer when targetSdkVersion is set to 26+. As of Android 8 (API level 26) getting DNS server information has becomei more restrictive and can only be accessed using the Connectivity Manager. It is necessary to pass the connectivity manager to c-ares via JNI. Also, the ACCESS_NETWORK_STATE permission must be present in the Android application. Android older than 8 do not need to to be initialized as they are less restrictive. However, this is a run time not compile time limitation. Proper Android initialization should take place regardless of the targeted Android version. Deinitialization will take place though \fIares_library_cleanup(3)\fP. The \fBares_library_init_jvm\fP function allows the caller to register the JVM with c-ares. It's meant to be called during JNI_OnLoad because you're guaranteed to have the JVM in that function. The JVM is required in order to use the Connectivity Manager registered using \fIares_library_init_android(3)\fP. This must be call before \fIares_library_init_android(3)\fP. The \fBares_library_android_initialized\fP function can be used to check whether c-ares has been initialized for use with Android. .SH RETURN VALUES ARES_SUCCESS will be returned on success otherwise an error code will be returned. .SH THREAD SAFETY .B These init functions are not thread safe. You have to call it once the program has started, but this call must be done before the program starts any other thread. This is required to avoid potential race conditions in library initialization, and also due to the fact these might call functions from other libraries that are thread unsafe, and could conflict with any other thread that is already using these other libraries. .SH JNI Accessing the Connectivity Manager though Java: Register the \fIares_library_android_init\fP. .nf static JNINativeMethod funcs[] = { { "initialize_native", "(Landroid/net/ConnectivityManager;)I", (void *)&ares_library_init_android} }; JNIEXPORT jint JNICALL JNI_OnLoad(JavaVM *vm, void *reserved) { JNIEnv *env = NULL; jclass cls = NULL; jint res; if ((*vm)->GetEnv(vm, (void **)&env, JNI_VERSION_1_6) != JNI_OK) return -1; cls = (*env)->FindClass(env, JNIT_CLASS); if (cls == NULL) return -1; res = (*env)->RegisterNatives(env, cls, funcs, sizeof(funcs)/sizeof(funcs[0])); if (res != 0) return -1; ares_library_init_jvm(vm); return JNI_VERSION_1_6; } .fi Calling the registered function from Java: .nf public class MyObject { static { System.loadLibrary("cares"); } private static native boolean initialize_native(ConnectivityManager connectivity_manager); public static boolean initialize(Context context) { initialize_native((ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE)); } } .fi Initializing the Connectivity Manager in JNI directly using an Android Context.

The parameter .I name gives the alias name or the base of the query name as a NUL-terminated C string of period-separated labels; if it ends with a period, the channel's search domains will not be used. Periods and backslashes within a label must be escaped with a backslash. The parameters .I dnsclass and .I type give the class and type of the query using the values defined in .BR .

The callback need not and should not attempt to free the memory pointed to by .IR hostent ; the ares library will free it when the callback returns. If the query did not complete successfully, .I hostent will be .BR NULL . .PP When the associated callback is called, it is called with a channel lock so care must be taken to ensure any processing is minimal to prevent DNS channel stalls. The callback may be triggered from a different thread than the one which called \fIares_gethostbyname(3)\fP.

Initializations done by this function remain effective until a number of calls to \fIares_library_cleanup(3)\fP equal to the number of calls to this function are performed. .PP Successive calls to this function do nothing further, only the first call done when c-ares is in an uninitialized state is actually effective. .PP The .I flags parameter is a bit pattern that tells c-ares exactly which features should be initialized, as described below. Set the desired bits by ORing the values together. In normal operation you should specify \fIARES_LIB_INIT_ALL\fP. Don't use any other value unless you are familiar with it and trying to control some internal c-ares feature. .PP The .B ares_library_init_mem function allows the caller to provide memory management functions that the c-ares library will be use instead of \fImalloc(3)\fP, \fIfree(3)\fP and \fIrealloc(3)\fP. .PP .B This function is not thread safe. You have to call it once the program has started, but this call must be done before the program starts any other thread. This is required to avoid potential race conditions in library initialization, and also due to the fact that \fIares_library_init(3)\fP might call functions from other libraries that are thread unsafe, and could conflict with any other thread that is already using these other libraries. .PP On Windows platforms, the library user should ensure that \fIWSAStartup()\fP is called before the c-ares library is initialized and used. .PP Win32/64 application DLLs shall not call \fIares_library_init(3)\fP from the DllMain function. Doing so will produce deadlocks and other problems. .SH FLAGS .TP 5 .B ARES_LIB_INIT_ALL Initialize everything possible. This sets all known bits. .TP .B ARES_LIB_INIT_WIN32 Initialize Win32/64 specific libraries. As of c-ares 1.19.0, this is ignored as there are no currently dynamically loaded libraries. .TP .B ARES_LIB_INIT_NONE Initialize nothing extra. This sets no bit. .SH RETURN VALUE Upon successful completion, \fIares_library_init(3)\fP returns 0. Otherwise, a non-zero error number is returned to indicate the error. Except for \fIares_strerror(3)\fP, you shall not call any other c-ares function upon \fIares_library_init(3)\fP failure. .SH AVAILABILITY This function was first introduced in c-ares version 1.7.0 along with the definition of preprocessor symbol \fICARES_HAVE_ARES_LIBRARY_INIT\fP as an indication of the availability of this function. Its recursive behavior, which requires a matching number of calls to \fIares_library_cleanup(3)\fP in order to deinitialize the library, is present since c-ares version 1.10.0. Earlier versions would deinitialize the library on the first call to \fIares_library_cleanup(3)\fP. .PP Since the introduction of this function it is absolutely mandatory to call it for any Win32/64 program using c-ares. .PP Non-Win32/64 systems can still use c-ares version 1.7.0 without calling \fIares_library_init(3)\fP due to the fact that \fIcurrently\fP it is nearly a do-nothing function on non-Win32/64 platforms at this point. .SH SEE ALSO .BR ares_library_cleanup (3), .BR ares_strerror (3) .SH AUTHOR Yang Tse .PP Copyright 1998 by the Massachusetts Institute of Technology. .br Copyright (C) 2004-2009 by Daniel Stenberg. c-ares-1.27.0/docs/ares_parse_srv_reply.30000644000175000017500000000323214566043726013716 .\" .\" Copyright 1998 by the Massachusetts Institute of Technology. .\" SPDX-License-Identifier: MIT .\" .TH ARES_PARSE_SRV_REPLY 3 "4 August 2009" .SH NAME ares_parse_srv_reply \- Parse a reply to a DNS query of type SRV .SH SYNOPSIS .nf #include int ares_parse_srv_reply(const unsigned char* \fIabuf\fP, int \fIalen\fP, struct ares_srv_reply** \fIsrv_out\fP); .fi .SH DESCRIPTION The .B ares_parse_srv_reply function parses the response to a query of type SRV into a linked list of .I struct ares_srv_reply The parameters .I abuf and .I alen give the contents of the response.

"20 Nov 2009" .SH NAME ares_set_socket_callback \- Set a socket creation callback .SH SYNOPSIS .nf #include typedef int (*ares_sock_create_callback)(ares_socket_t \fIsocket_fd\fP, int \fItype\fP, void *\fIuserdata\fP) void ares_set_socket_callback(ares_channel_t *\fIchannel\fP, ares_sock_create_callback \fIcallback\fP, void *\fIuserdata\fP) .PP .B cc file.c -lcares .fi .SH DESCRIPTION .PP This function sets a \fIcallback\fP in the given ares channel handle.

The provided linked list argument may be the result of a previous call to \fBares_get_servers_ports(3)\fP or a linked list of \fBares_addr_port_node\fP structs set up by other means. .PP This function replaces any potentially previously configured name servers with the ones given in the linked list. So, in order to configure a channel with more than one name server all the desired ones must be specified in a single list. Though not recommended, passing NULL will clear all configured servers and make an inoperable channel, this may be advantageous for test simulation but unlikely to be useful in production. .PP The function does not take ownership of the linked list argument.

It is recommended to use \fBares_init_options(3)\fP instead and to set or make configurable the appropriate options for your application. The \fBares_init_options(3)\fP function initializes a communications channel for name service lookups. If it returns successfully, \fBares_init_options(3)\fP will set the variable pointed to by \fIchannelptr\fP to a handle used to identify the name service channel. The caller should invoke \fIares_destroy(3)\fP on the handle when the channel is no longer needed. It is recommended for an application to have at most one ares channel and use this for all DNS queries for the life of the application. When system configuration changes, \fIares_reinit(3)\fP can be called to reload the configuration if necessary. The recommended concurrent query limit is about 32k queries, but remembering that when specifying AF_UNSPEC for \fBares_getaddrinfo(3)\fP or \fBares_gethostbyname(3)\fP, they may spawn 2 queries internally. The reason for the limit is c-ares does not allow duplicate DNS query ids (which have a maximum of 64k) to be oustanding at a given time, and it must randomly search for an available id thus 32k will limit the number of searches. This limitation should not be a concern for most implementations and c-ares may implement queuing in future releases to lift this limitation. The \fIoptmask\fP parameter generally specifies which fields in the structure pointed to by \fIoptions\fP are set, as follows: .TP 18 .B ARES_OPT_FLAGS .B int \fIflags\fP; .br Flags controlling the behavior of the resolver: .RS 4 .TP 23 .B ARES_FLAG_USEVC Always use TCP queries (the "virtual circuit") instead of UDP queries. Normally, TCP is only used if a UDP query yields a truncated result. .TP 23 .B ARES_FLAG_PRIMARY Only query the first server in the list of servers to query. .TP 23 .B ARES_FLAG_IGNTC If a truncated response to a UDP query is received, do not fall back to TCP; simply continue on with the truncated response. .TP 23 .B ARES_FLAG_NORECURSE Do not set the "recursion desired" bit on outgoing queries, so that the name server being contacted will not try to fetch the answer from other servers if it doesn't know the answer locally. Be aware that ares will not do the recursion for you. Recursion must be handled by the application calling ares if \fIARES_FLAG_NORECURSE\fP is set. .TP 23 .B ARES_FLAG_STAYOPEN Do not close communications sockets when the number of active queries drops to zero. .TP 23 .B ARES_FLAG_NOSEARCH Do not use the default search domains; only query hostnames as-is or as aliases. .TP 23 .B ARES_FLAG_NOALIASES Do not honor the HOSTALIASES environment variable, which normally specifies a file of hostname translations. .TP 23 .B ARES_FLAG_NOCHECKRESP Do not discard responses with the SERVFAIL, NOTIMP, or REFUSED response code or responses whose questions don't match the questions in the request. Primarily useful for writing clients which might be used to test or debug name servers. .TP 23 .B ARES_FLAG_EDNS Include an EDNS pseudo-resource record (RFC 2671) in generated requests. As of v1.22, this is on by default if flags are otherwise not set. .TP 23 .B ARES_FLAG_NO_DFLT_SVR Do not attempt to add a default local named server if there are no other servers available. Instead, fail initialization with \fIARES_ENOSERVER\fP. .RE .TP 18 .B ARES_OPT_TIMEOUT .B int \fItimeout\fP; .br The number of seconds each name server is given to respond to a query on the first try. (After the first try, the timeout algorithm becomes more complicated, but scales linearly with the value of \fItimeout\fP.) The default is two seconds. This option is being deprecated by \fIARES_OPT_TIMEOUTMS\fP starting in c-ares 1.5.2. .TP 18 .B ARES_OPT_TIMEOUTMS .B int \fItimeout\fP; .br The number of milliseconds each name server is given to respond to a query on the first try. (After the first try, the timeout algorithm becomes more complicated, but scales linearly with the value of \fItimeout\fP.) The default is two seconds. Note that this option is specified with the same struct field as the former \fIARES_OPT_TIMEOUT\fP, it is but the option bits that tell c-ares how to interpret the number. This option was added in c-ares 1.5.2. .TP 18 .B ARES_OPT_TRIES .B int \fItries\fP; .br The number of tries the resolver will try contacting each name server before giving up. The default is three tries. .TP 18 .B ARES_OPT_NDOTS .B int \fIndots\fP; .br The number of dots which must be present in a domain name for it to be queried for "as is" prior to querying for it with the default domain extensions appended. The default value is 1 unless set otherwise by resolv.conf or the RES_OPTIONS environment variable. .TP 18 .B ARES_OPT_MAXTIMEOUTMS .B int \fImaxtimeout\fP; .br The upper bound for timeout between sequential retry attempts. When retrying queries, the timeout is increased from the requested timeout parameter, this caps the value. .TP 18 .B ARES_OPT_UDP_PORT .B unsigned short \fIudp_port\fP; .br The port to use for queries over UDP, in host byte order. The default value is 53, the standard name service port. .TP 18 .B ARES_OPT_TCP_PORT .B unsigned short \fItcp_port\fP; .br The port to use for queries over TCP, in host byte order. The default value is 53, the standard name service port. .TP 18 .B ARES_OPT_SERVERS .B struct in_addr *\fIservers\fP; .br .B int \fInservers\fP; .br The list of IPv4 servers to contact, instead of the servers specified in resolv.conf or the local named. In order to allow specification of either IPv4 or IPv6 name servers, the \Bares_set_servers(3)\fP function must be used instead. .TP 18 .B ARES_OPT_DOMAINS .B char **\fIdomains\fP; .br .B int \fIndomains\fP; .br The domains to search, instead of the domains specified in resolv.conf or the domain derived from the kernel hostname variable. .TP 18 .B ARES_OPT_LOOKUPS .B char *\fIlookups\fP; .br The lookups to perform for host queries. .I lookups should be set to a string of the characters "b" or "f", where "b" indicates a DNS lookup and "f" indicates a lookup in the hosts file. .TP 18 .B ARES_OPT_SOCK_STATE_CB .B void (*\fIsock_state_cb\fP)(void *data, ares_socket_t socket_fd, int readable, int writable); .br .B void *\fIsock_state_cb_data\fP; .br A callback function to be invoked when a socket changes state. .I socket_fd will be passed the socket whose state has changed; .I readable will be set to true if the socket should listen for read events, and .I writable will be set to true if the socket should listen for write events. The value of .I sock_state_cb_data will be passed as the .I data argument. Cannot be used with \fBARES_OPT_EVENT_THREAD\fP. .TP 18 .B ARES_OPT_SORTLIST .B struct apattern *\fIsortlist\fP; .br .B int \fInsort\fP; .br A list of IP address ranges that specifies the order of preference that results from \fIares_gethostbyname\fP should be returned in. Note that this can only be used with a sortlist retrieved via \fBares_save_options(3)\fP (because .B struct apattern is opaque); to set a fresh sort list, use \fBares_set_sortlist(3)\fP. .TP 18 .B ARES_OPT_SOCK_SNDBUF .B int \fIsocket_send_buffer_size\fP; .br The send buffer size to set for the socket. .TP 18 .B ARES_OPT_SOCK_RCVBUF .B int \fIsocket_receive_buffer_size\fP; .br The receive buffer size to set for the socket. .TP 18 .B ARES_OPT_EDNSPSZ .B int \fIednspsz\fP; .br The message size to be advertised in EDNS; only takes effect if the .B ARES_FLAG_EDNS flag is set. Defaults to 1232, the recommended size. .TP 18 .B ARES_OPT_RESOLVCONF .B char *\fIresolvconf_path\fP; .br The path to use for reading the resolv.conf file. The .I resolvconf_path should be set to a path string, and will be honoured on *nix like systems. The default is .B /etc/resolv.conf .br .TP 18 .B ARES_OPT_HOSTS_FILE .B char *\fIhosts_path\fP; .br The path to use for reading the hosts file.

The default is .B /etc/hosts .br .TP 18 .B ARES_OPT_UDP_MAX_QUERIES .B int \fIudp_max_queries\fP; .br The maximum number of udp queries that can be sent on a single ephemeral port to a given DNS server before a new ephemeral port is assigned. Any value of 0 or less will be considered unlimited, and is the default. .br .TP 18 .B ARES_OPT_QUERY_CACHE .B unsigned int \fIqcache_max_ttl\fP; .br Enable the built-in query cache. Will cache queries based on the returned TTL in the DNS message. Only fully successful and NXDOMAIN query results will be cached. Fill in the \fIqcache_max_ttl\fP with the maximum number of seconds a query result may be cached which will override a larger TTL in the response message. This must be a non-zero value otherwise the cache will be disabled. Choose a reasonable value for your application such as 300 (5 minutes) or 3600 (1 hour). .br .TP 18 .B ARES_OPT_EVENT_THREAD .B ares_evsys_t \fIevsys\fP; .br Enable the built-in event thread (Recommended). Introduced in c-ares 1.26.0. Set the \fIevsys\fP parameter to \fBARES_EVSYS_DEFAULT\fP (0). Other values are reserved for testing and should not be used by integrators. This option cannot be used with the \fBARES_OPT_SOCK_STATE_CB\fP option, nor the \fIares_set_socket_functions(3)\fP or \fIares_set_socket_configure_callback(3)\fP functions. When enabled, the integrator is no longer responsible for notifying c-ares of any events on the file descriptors, so \fIares_process(3)\fP nor \fIares_process_fd(3)\fP should ever be called when this option is enabled. Use \fIares_threadsafety(3)\fP to determine if this option is available to be used. Returns \fBARES_ENOTIMP\fP if this option is passed but not available, and \fBARES_ESERVFAIL\fP if there is a critical failure during initialization of the event thread. .br .PP The \fIoptmask\fP parameter also includes options without a corresponding field in the .B ares_options structure, as follows: .TP 23 .B ARES_OPT_ROTATE Perform round-robin selection of the nameservers configured for the channel for each resolution. .TP 23 .B ARES_OPT_NOROTATE Do not perform round-robin nameserver selection; always use the list of nameservers in the same order. .PP .SH RETURN VALUES \fBares_init_options(3)\fP and \fBares_init(3)\fP can return any of the following values: .TP 14 .B ARES_SUCCESS Initialization succeeded. .TP 14 .B ARES_EFILE A configuration file could not be read. .TP 14 .B ARES_ENOMEM The process's available memory was exhausted. .TP 14 .B ARES_ENOTINITIALIZED c-ares library initialization not yet performed. .TP 14 .B ARES_ENOSERVER No DNS servers were available to use. .SH NOTES When initializing from .B /etc/resolv.conf, (or, alternatively when specified by the .I resolvconf_path path location) \fBares_init_options(3)\fP and \fBares_init(3)\fP reads the \fIdomain\fP and \fIsearch\fP directives to allow lookups of short names relative to the domains specified.

The callback need not and should not attempt to free the memory pointed to by .IR hostent ; the ares library will free it when the callback returns. If the query did not complete successfully, .I hostent will be .BR NULL . .PP When the associated callback is called, it is called with a channel lock so care must be taken to ensure any processing is minimal to prevent DNS channel stalls.

Completion or failure of the query may happen immediately, or may happen later as network events are processed. .PP When the associated callback is called, it is called with a channel lock so care must be taken to ensure any processing is minimal to prevent DNS channel stalls. The callback may be triggered from a different thread than the one which called \fIares_send(3)\fP. For integrators running their own event loops and not using \fBARES_OPT_EVENT_THREAD\fP, care needs to be taken to ensure any file descriptor lists are updated immediately within the eventloop when notified. .PP The callback argument .I arg is copied from the .B ares_send argument .IR arg . The callback argument .I status indicates whether the query succeeded and, if not, how it failed. It may have any of the following values: .TP 19 .B ARES_SUCCESS The query completed. .TP 19 .B ARES_EBADQUERY The query buffer was poorly formed (was not long enough for a DNS header or was too long for TCP transmission). .TP 19 .B ARES_ETIMEOUT No name servers responded within the timeout period. .TP 19 .B ARES_ECONNREFUSED No name servers could be contacted. .TP 19 .B ARES_ENOMEM Memory was exhausted. .TP 19 .B ARES_ECANCELLED The query was cancelled. .TP 19 .B ARES_EDESTRUCTION The name service channel .I channel is being destroyed; the query will not be completed. .TP 19 .B ARES_ENOSERVER The query will not be completed because no DNS servers were configured on the channel. .PP The callback argument .I timeouts reports how many times a query timed out during the execution of the given request. .PP If the query completed, the callback argument .I abuf points to a result buffer of length .IR alen . If the query did not complete, .I abuf will be NULL and .I alen will be 0. .PP Unless the flag .B ARES_FLAG_NOCHECKRESP was set at channel initialization time, .B ares_send will normally ignore responses whose questions do not match the questions in .IR qbuf , as well as responses with reply codes of .BR SERVFAIL , .BR NOTIMP , and .BR REFUSED . Unlike other query functions in the ares library, however, .B ares_send does not inspect the header of the reply packet to determine the error status, so a callback status of .B ARES_SUCCESS does not reflect as much about the response as for other query functions. .SH SEE ALSO .BR ares_process (3), .BR ares_dns_record (3) .SH AUTHOR Greg Hudson, MIT Information Systems .br Copyright 1998 by the Massachusetts Institute of Technology. c-ares-1.27.0/docs/ares_dns_record_create.30000644000175000017500000000017414530123235014127 .\" Copyright (C) 2023 The c-ares project and its contributors. .\" SPDX-License-Identifier: MIT .so man3/ares_dns_record.3 c-ares-1.27.0/docs/ares_dns_write.30000644000175000017500000000017414530123235012460 .\" Copyright (C) 2023 The c-ares project and its contributors. .\" SPDX-License-Identifier: MIT .so man3/ares_dns_record.3 c-ares-1.27.0/docs/ares_dns_opcode_tostr.30000644000175000017500000000014314530123235014026 .\" .\" Copyright (C) Daniel Stenberg .\" SPDX-License-Identifier: MIT .so man3/ares_dns_mapping.3 c-ares-1.27.0/docs/ares_save_options.30000644000175000017500000000407414566043726013215 .\" .\" Copyright 1998 by the Massachusetts Institute of Technology. .\" SPDX-License-Identifier: MIT .\" .TH ARES_SAVE_OPTIONS 3 "5 March 2010" .SH NAME ares_save_options \- Save configuration values obtained from initialized ares_channel .SH SYNOPSIS .nf #include int ares_save_options(ares_channel_t *\fIchannel\fP, struct ares_options *\fIoptions\fP, int *\fIoptmask\fP) .fi .SH DESCRIPTION The \fBares_save_options(3)\fP function saves the channel data identified by .IR channel , into the options struct identified by .IR options , and saves the mask of options which are set to the integer pointer (passed by reference) identified by .IR optmask .

If there was more than one previous call to \fIares_library_init(3)\fP, this function uninitializes the c-ares library only if it is the call matching the call to \fIares_library_init(3)\fP which initialized the library (usually the very first call to \fIares_library_init(3)\fP). Other calls to \fIares_library_cleanup(3)\fP have no effect other than decrementing an internal counter. .PP This function must be called when the program using c-ares will no longer need any c-ares function.

The limitations can vary from system to system, but in general if the file descriptor value itself is greater than 1024 (not the count but the actual value), this can lead to \fBares_fds(3)\fP writing out of bounds which will cause a system crash. In modern networking clients, it is not unusual to have file descriptor values above 1024, especially when a library is pulled in as a dependency into a larger project. c-ares does not attempt to detect this condition to prevent crashes due to both implementation-defined behavior in the OS as well as integrator-controllable tunables which may impact the limits.

We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object.

Publishing Information ---------------------- All known and public c-ares vulnerabilities will be listed on [the c-ares web site](https://c-ares.org/vulns.html). Security vulnerabilities should not be entered in the project's public bug tracker unless the necessary configuration is in place to limit access to the issue to only the reporter and the project's security team. Vulnerability Handling ---------------------- The typical process for handling a new security vulnerability is as follows. No information should be made public about a vulnerability until it is formally announced at the end of this process. That means, for example that a bug tracker entry must NOT be created to track the issue since that will make the issue public and it should not be discussed on the project's public mailing list. Also messages associated with any commits should not make any reference to the security nature of the commit if done prior to the public announcement. - The person discovering the issue, the reporter, reports the vulnerability privately to `c-ares-security@haxx.se`. That's an email alias that reaches a handful of selected and trusted people. - Messages that do not relate to the reporting or managing of an undisclosed security vulnerability in c-ares are ignored and no further action is required. - A person in the security team sends an e-mail to the original reporter to acknowledge the report. - The security team investigates the report and either rejects it or accepts it. - If the report is rejected, the team writes to the reporter to explain why. - If the report is accepted, the team writes to the reporter to let him/her know it is accepted and that they are working on a fix. - The security team discusses the problem, works out a fix, considers the impact of the problem and suggests a release schedule. This discussion should involve the reporter as much as possible. - The release of the information should be "as soon as possible" and is most often synced with an upcoming release that contains the fix. If the reporter, or anyone else, thinks the next planned release is too far away then a separate earlier release for security reasons should be considered. - Write a security advisory draft about the problem that explains what the problem is, its impact, which versions it affects, solutions or workarounds, when the release is out and make sure to credit all contributors properly. - Request a CVE number from [distros@openwall](http://oss-security.openwall.org/wiki/mailing-lists/distros) when also informing and preparing them for the upcoming public security vulnerability announcement - attach the advisory draft for information. Note that 'distros' won't accept an embargo longer than 19 days. - Update the "security advisory" with the CVE number. - The security team commits the fix in a private branch. The commit message should ideally contain the CVE number. This fix is usually also distributed to the 'distros' mailing list to allow them to use the fix prior to the public announcement. - At the day of the next release, the private branch is merged into the master branch and pushed. Once pushed, the information is accessible to the public and the actual release should follow suit immediately afterwards. - The project team creates a release that includes the fix. - The project team announces the release and the vulnerability to the world in the same manner we always announce releases. It gets sent to the c-ares mailing list and the oss-security mailing list. - The security web page on the web site should get the new vulnerability mentioned. C-ARES-SECURITY (at haxx dot se) -------------------------------- Who is on this list? There are a couple of criteria you must meet, and then we might ask you to join the list or you can ask to join it. It really isn't very formal. We basically only require that you have a long-term presence in the c-ares project and you have shown an understanding for the project and its way of working. You must've been around for a good while and you should have no plans in vanishing in the near future. We do not make the list of partipants public mostly because it tends to vary somewhat over time and a list somewhere will only risk getting outdated. c-ares-1.27.0/README.md0000644000175000017500000000726214566043726007737 # [![c-ares logo](https://c-ares.org/art/c-ares-logo.svg)](https://c-ares.org/) [![Build Status](https://api.cirrus-ci.com/github/c-ares/c-ares.svg?branch=main)](https://cirrus-ci.com/github/c-ares/c-ares) [![Windows Build Status](https://ci.appveyor.com/api/projects/status/aevgc5914tm72pvs/branch/master?svg=true)](https://ci.appveyor.com/project/c-ares/c-ares/branch/master) [![Coverage Status](https://coveralls.io/repos/github/c-ares/c-ares/badge.svg)](https://coveralls.io/github/c-ares/c-ares) [![CII Best Practices](https://bestpractices.coreinfrastructure.org/projects/291/badge)](https://bestpractices.coreinfrastructure.org/projects/291) [![Fuzzing Status](https://oss-fuzz-build-logs.storage.googleapis.com/badges/c-ares.svg)](https://bugs.chromium.org/p/oss-fuzz/issues/list?sort=-opened&can=1&q=proj:c-ares) [![Bugs](https://sonarcloud.io/api/project_badges/measure?project=c-ares_c-ares&metric=bugs)](https://sonarcloud.io/summary/new_code?id=c-ares_c-ares) [![Coverity Scan Status](https://scan.coverity.com/projects/c-ares/badge.svg)](https://scan.coverity.com/projects/c-ares) This is c-ares, an asynchronous resolver library. It is intended for applications which need to perform DNS queries without blocking, or need to perform multiple DNS queries in parallel. The primary examples of such applications are servers which communicate with multiple clients and programs with graphical user interfaces. The full source code is available in the ['c-ares' release archives](https://c-ares.org/download/), and in a git repository: https://github.com/c-ares/c-ares. See the [INSTALL.md](INSTALL.md) file for build information. If you find bugs, correct flaws, have questions or have comments in general in regard to c-ares (or by all means the original ares too), get in touch with us on the c-ares mailing list: https://lists.haxx.se/listinfo/c-ares c-ares is distributed under the MIT license. You'll find all c-ares details and news here: https://c-ares.org/ ## Notes for c-ares hackers * The distributed `ares_build.h` file is only intended to be used on systems which can not run the also distributed configure script. * The distributed `ares_build.h` file is generated as a copy of `ares_build.h.dist` when the c-ares source code distribution archive file is originally created. * If you check out from git on a non-configure platform, you must run the appropriate `buildconf*` script to set up `ares_build.h` and other local files before being able to compile the library. * On systems capable of running the `configure` script, the `configure` process will overwrite the distributed `ares_build.h` file with one that is suitable and specific to the library being configured and built, this new file is generated from the `ares_build.h.in` template file. * If you intend to distribute an already compiled c-ares library you **MUST** also distribute along with it the generated `ares_build.h` which has been used to compile it. Otherwise, the library will be of no use for the users of the library that you have built. It is **your** responsibility to provide this file. No one at the c-ares project can know how you have built the library. * File `ares_build.h` includes platform and configuration dependent info, and must not be modified by anyone. Configure script generates it for you. * We cannot assume anything else but very basic compiler features being present. While c-ares requires an ANSI C compiler to build, some of the earlier ANSI compilers clearly can't deal with some preprocessor operators. * Newlines must remain unix-style for older compilers' sake. * Comments must be written in the old-style /* unnested C-fashion */ * Try to keep line lengths below 80 columns. c-ares-1.27.0/AUTHORS0000644000175000017500000000235214115646145007515 c-ares is based on ares, and these are the people that have worked on it since the fork was made: Albert Chin Alex Loukissas Alexander Klauer Alexander Lazic Alexey Simak Andreas Rieke Andrew Andkjar Andrew Ayer Andrew C.

Generated with git2changes.pl Version 1.27.0 (22 Feb 2024) GitHub (22 Feb 2024) - [Brad House brought this change] Release 1.27.0 (#715) release prep for 1.27.0 release - [Brad House brought this change] Merge pull request from GHSA-mg26-v6qh-x48q - [Oliver Welsh brought this change] Add flag to not use a default local named server on channel initialization (#713) Hello, I work on an application for Microsoft which uses c-ares to perform DNS lookups. We have made some minor changes to the library over time, and would like to contribute these back to the project in case they are useful more widely. This PR adds a new channel init flag, described below. Please let me know if I can include any more information to make this PR better/easier for you to review. Thanks! **Summary** When initializing a channel with `ares_init_options()`, if there are no nameservers available (because `ARES_OPT_SERVERS` is not used and `/etc/resolv.conf` is either empty or not available) then a default local named server will be added to the channel. However in some applications a local named server will never be available. In this case, all subsequent queries on the channel will fail. If we know this ahead of time, then it may be preferred to fail channel initialization directly rather than wait for the queries to fail. This gives better visibility, since we know that the failure is due to missing servers rather than something going wrong with the queries. This PR adds a new flag `ARES_FLAG_NO_DFLT_SVR`, to indicate that a default local named server should not be added to a channel in this scenario. Instead, a new error `ARES_EINITNOSERVER` is returned and initialization fails. **Testing** I have added 2 new FV tests: - `ContainerNoDfltSvrEmptyInit` to test that initialization fails when no nameservers are available and the flag is set. - `ContainerNoDfltSvrFullInit` to test that initialization still succeeds when the flag is set but other nameservers are available. Existing FVs are all passing. **Documentation** I have had a go at manually updating the docs to describe the new flag/error, but couldn't see any contributing guidance about testing this. Please let me know if you'd like anything more here. --------- Fix By: Oliver Welsh (@oliverwelsh) Brad House (18 Feb 2024) - badge should be only main branch - put logo in readme - clang-format GitHub (17 Feb 2024) - [Brad House brought this change] Add ares_queue_active_queries() (#712) Add a function to request the number of active queries from an ares channel. This will return the number of inflight requests to dns servers. Some functions like `ares_getaddrinfo()` when using `AF_UNSPEC` may enqueue multiple queries which will be reflected in this count. In the future, if we implement support for queuing (e.g. for throttling purposes), and/or implement support for tracking user-requested queries (e.g. for cancelation), we can provide additional functions for inspecting those queues.

Fix By: Gisle Vanem (@gvanem) GitHub (24 Jan 2024) - [Brad House brought this change] Event Subsystem: No longer require integrators to have their own (#696) This PR implements an event thread to process all events on file descriptors registered by c-ares. Prior to this feature, integrators were required to understand the internals of c-ares and how to monitor file descriptors and timeouts and process events. Implements OS-specific efficient polling such as epoll(), kqueue(), or IOCP, and falls back to poll() or select() if otherwise unsupported. At this point, it depends on basic threading primitives such as pthreads or windows threads. If enabled via the ARES_OPT_EVENT_THREAD option passed to ares_init_options(), then socket callbacks cannot be used.

I believe it has been copied from the "real" lib where it's used in the INSTALL_INTERFACE context. But because caresinternal is never installed we don't need that include here. * cmake: drop CARES_TOPLEVEL_DIR variable The CARES_TOPLEVEL_DIR variable is the same as the automatically created PROJECT_SOURCE_DIR variable.

Disable static by default on Windows however since it can't build both simultaneously. - autotools: update logic for building tests to provide more feedback - set winver consistently across build systems GitHub (28 Dec 2023) - [Brad House brought this change] Autotools: rework to simplify and fix recent issues (#674) Completely rework the autotools build system, issues have cropped up due to the complexity and could cause issues on even semi-modern Linux systems (Ubuntu 20.04 for example). Changes include: Remove all curl/xc/cares m4 helper files, they go overboard on detections of functions and datatypes. Go back to more plain autoconf macros as they've come a long way over the years. Use known systems and heuristics to determine datatypes for functions like send() and recv(), rather than the error prone detection which required thousands of permutations and might still get it wrong. Remove unneeded configure arguments like --enable-debug or --enable-optimize, its more common for people to simply pass their own CFLAGS on the command line. Only require CARES_STATICLIB definition on Windows static builds, its not necessary ever for other systems, even when hiding non-public symbols. Remove some function and definition detections that were never used in c-ares The test framework is now embedded into the toplevel configure system, there was no need to chain build the test system as it is never built externally to c-ares. As a side-effect of the changes, a configure run completes in about 25% of the original time. This has been tested on various Linux distributions (of varying age), FreeBSD, MacOS, Windows (via MSYS2 with Mingw), and Solaris10/11 (by @dfandrich), AIX 7.3 (by @dfandrich). It is not unlikely that this may have broken more esoteric or legacy systems, and we'll likely need to be ready to accept bug reports and patches, but it has removed over 10k lines of build system code. It is very likely any issues that crop up will add far fewer lines of code to fix such systems.

This will cause a DNS entry to be created like `fe80::1%iface`, since all link-local network interfaces are technically part of the same /10 subnet, it must be told what interface to send packets through explicitly if there are multiple physical interfaces. This PR adds support for the %iface modifier when setting DNS servers via `/etc/resolv.conf` as well as via `ares_set_servers_csv()`. For MacOS and iOS it is assumed that libresolve will set the `sin6_scope_id` and should be supported, but my test systems don't seem to read the Router Advertisement for RDNSS link-local. Specifying the link-local dns server on MacOS via adig has been tested and confirmed working. For Windows, this is similar to MacOS in that the system doesn't seem to honor the RDNSS RA, but specifying manually has been tested to work. At this point, Android support does not exist.

It appears they do this for test cases to simulate DNS unavailable or similar. Presumably they could achieve the same effect in other ways (point to localhost on a port that isn't in use). But it seems like this might be wide-spread enough to cause headaches so we just will document and test for this behavior, clearly it hasn't caused "issues" for anyone with the old behavior. See: https://github.com/nodejs/node/pull/50800 Fix By: Brad House (@bradh352) GitHub (19 Nov 2023) - [Brad House brought this change] Query Cache support (#625) This PR implements a query cache at the lowest possible level, the actual dns request and response messages. Only successful and `NXDOMAIN` responses are cached. The lowest TTL in the response message determines the cache validity period for the response, and is capped at the configuration value for `qcache_max_ttl`. For `NXDOMAIN` responses, the SOA record is evaluated. For a query to match the cache, the opcode, flags, and each question's class, type, and name are all evaluated. This is to prevent matching a cached entry for a subtly different query (such as if the RD flag is set on one request and not another). For things like ares_getaddrinfo() or ares_search() that may spawn multiple queries, each individual message received is cached rather than the overarching response. This makes it possible for one query in the sequence to be purged from the cache while others still return cached results which means there is no chance of ever returning stale data. We have had a lot of user requests to return TTLs on all the various parsers like `ares_parse_caa_reply()`, and likely this is because they want to implement caching mechanisms of their own, thus this PR should solve those issues as well. Due to the internal data structures we have these days, this PR is less than 500 lines of new code.

Fix By: Brad House (@bradh352) - Fix /etc/hosts processing performance with all entries using same IP address Some users use blacklist files like https://github.com/StevenBlack/hosts which can contain 200k+ host entries all pointing to 0.0.0.0. Due to the merge logic in the new hosts processor, all those entries will be associated as aliases for the same ip address. The first issue is that it attempts to check the status of all the hosts for the merged entry, when it should only be checking the new hosts added to the merged entry, so this caused exponential time as the entries got longer. The next issue is if searching for one of those hosts, it would append all the matches as cnames/aliases, but there is zero use for 200k aliases being appended to a lookup, so we are artificially capping this to 100.

Now it can focus strictly on formatting of output data for printing. It simply iterates across the parsed DNS packet and queries for the RRs, parameters for each RR, and the datatypes for each parameter. adig will now automatically pick up new RRs from the c-ares library due to the dynamic nature. The adig format also now more closely resembles that of BIND's `dig` output. A few more helpers needed to be added to the c-ares library that were missing. There ware a couple of minor bugs and enhancements also needed.

Fix By: Brad House (@bradh352) - [Brad House brought this change] `ares_channel` -> `ares_channel_t *`: don't bury the pointer (#595) `ares_channel` is defined as `typedef struct ares_channeldata *ares_channel;`. The problem with this, is it embeds the pointer into the typedef, which means an `ares_channel` can never be declared as `const` as if you write `const ares_channel channel`, that expands to `struct ares_channeldata * const ares_channel` and not `const struct ares_channeldata *channel`. We will now typedef `ares_channel_t` as `typedef struct ares_channeldata ares_channel_t;`, so if you write `const ares_channel_t *channel`, it properly expands to `const struct ares_channeldata *channel`. We are maintaining the old typedef for API compatibility with existing integrations, and due to typedef expansion this should not even cause any compiler warnings for existing code. There are no ABI implications with this change. I could be convinced to keep existing public functions as `ares_channel` if a sufficient argument exists, but internally we really need make this change for modern best practices. This change will allow us to internally use `const ares_channel_t *` where appropriate. Whether or not we decide to change any public interfaces to use `const` may require further discussion on if there might be ABI implications (I don't think so, but I'm also not 100% sure what a compiler internally does with `const` when emitting machine code ... I think more likely ABI implications would occur going the opposite direction). FYI, This PR was done via a combination of sed and clang-format, the only manual code change was the addition of the new typedef, and a couple doc fixes :) Fix By: Brad House (@bradh352) Brad House (4 Nov 2023) - win32 warnings look good, remove commented out block - more msvc warnings - fix - docs: document setting servers can be done live - SonarCloud: more easy codesmells - clang-format - SonarCloud: fix up codesmells GitHub (3 Nov 2023) - [Brad House brought this change] Dynamic Server List (#594) This PR makes the server list a dynamic sorted list of servers. The sort order is [ consecutive failures, system config index ]. The server list can be updated via ares_set_servers_*(). Any queries currently directed to servers that are no longer in the list will be automatically re-queued to a different server. Also, any time a failure occurs on the server, the sort order of the servers will be updated so that the one with the fewest consecutive failures is chosen for the next query that goes on the wire, this way bad or non-responsive servers are automatically isolated. Since the server list is now dynamic, the tracking of query failures per server has been removed and instead is relying on the server sort order as previously described. This simplifies the logic while also reducing the amount of memory required per query. However, because of this dynamic nature, it may not be easy to determine the server attempt order for enqueued queries if there have been any failures. If using the ARES_OPT_ROTATE, this is now implemented to be a random selection of the configured servers. Since the server list is dynamic, its not possible to go to the next server as configuration could have changed between queries or attempts for the same query. Finally, this PR moved some existing functions into new files to logically separate them. This should address issues #550 and #440, while also setting the framework to implement #301. #301 needs a little more effort since it configures things other than the servers themselves (domains, search, sortlist, lookups), which need to make sure they can be safely updated.

Each row is an IP address followed by a list of space delimited hostnames that match the ip address. This is used for both forward and reverse lookups. We are caching the entire parsed hosts file for performance reasons. Some files may be quite sizable and as per Issue #458 can approach 1/2MB in size, and the parse overhead on a rapid succession of queries can be quite large. The entries are stored in forwards and backwards hashtables so we can get O(1) performance on lookup. The file is cached until the file modification timestamp changes (or 60s if there is no implemented stat() capability). The hosts file processing is quite unique. It has to merge all related hosts and ips into a single entry due to file formatting requirements. For instance take the below: ``` 127.0.0.1 localhost.localdomain localhost ::1 localhost.localdomain localhost 192.168.1.1 host.example.com host 192.168.1.5 host.example.com host 2620:1234::1 host.example.com host6.example.com host6 host ``` This will yield 2 entries. 1) ips: `127.0.0.1,::1` hosts: `localhost.localdomain,localhost` 2) ips: `192.168.1.1,192.168.1.5,2620:1234::1` hosts: `host.example.com,host,host6.example.com,host6` It could be argued that if searching for `192.168.1.1` that the `host6` hostnames should not be returned, but this implementation will return them since they are related (both ips have the fqdn of host.example.com). It is unlikely this will matter in the real world.

The old code was basically just some helper macros and functions for parsing an entire DNS message. The caller had to know the RFCs to use the parsers, except for some pre-made exceptions. The new parsing code parses the entire DNS message into an opaque data structure in a memory safe manner with various accessors for reading and manipulating the data. The existing parser helpers for the various record types were reimplemented as wrappers around the new parser. The accessors allow easy iteration across the DNS record datastructure, and can be used to easily create dig-like output without needing to know anything about the various record types and formats as dynamic helpers are provided for enumeration of values and data types of those values. At some point in the future, this new DNS record structure, accessors, and parser will be exposed publicly. This is not done at this point as we don't want to do that until the API is completely stable. Likely a write() function to output the DNS record back into an actual message buffer will be introduced with the stable API as well. Some subtle bugs in the existing code were uncovered, some which had test cases which turned out to be bogus. Validation with third-party implementations (e.g. BIND9) were performed to validate such cases were indeed bugs. Adding additional RR parsers such as for TLSA (#470) or SVCB/HTTPS (#566) are trivial now since focus can be put on only parsing the data within the RR, not the entire message. That said, as the new parser is not yet public, it isn't clear the best way to expose any new RRs (probably best to wait for the new parser to be public rather than hacking in another legacy function). Some additional RRs that are part of DNS RFC1035 or EDNS RFC6891 that didn't have previously implemented parsers are now also implemented (e.g. HINFO, OPT). Any unrecognized RRs are encapsulated into a "RAW_RR" as binary data which can be inserted or extracted, but are otherwise not interpreted in any way.

Fixes #532 Fix By: @Chilledheart and Brad House (@bradh352) - [Brad House brought this change] ares_getaddrinfo(): Fail faster on AF_UNSPEC if we've already received one address class (#551) As per #541, when using AF_UNSPEC with ares_getaddrinfo() (and in turn with ares_gethostbynam()) if we receive a successful response for one address class, we should not allow the other address class to continue on with retries, just return the address class we have. This will limit the overall query time to whatever timeout remains for the pending query for the other address class, it will not, however, terminate the other query as it may still prove to be successful (possibly coming in less than a millisecond later) and we'd want that result still. It just turns off additional error processing to get the result back quicker.

This value defaults to 0 (unlimited) to maintain existing compatibility, any positive number will cause new UDP ephemeral ports to be created once the threshold is reached, we'll call these 'connections' even though its technically wrong for UDP. Implementation Details: * Each server entry in a channel now has a linked-list of connections/ports for udp and tcp. The first connection in the list is the one most likely to be eligible to accept new queries. * Queries are now tracked by connection rather than by server. * Every time a query is detached from a connection, the connection that it was attached to will be checked to see if it needs to be cleaned up. * Insertion, lookup, and searching for connections has been implemented as O(1) complexity so the number of connections will not impact performance. * Remove is_broken from the server, it appears it would be set and immediately unset, so must have been invalidated via a prior patch. A future patch should probably track consecutive server errors and de-prioritize such servers. The code right now will always try servers in the order of configuration, so a bad server in the list will always be tried and may rely on timeout logic to try the next. * Various other cleanups to remove code duplication and for clarification. Fixes Bug: #444 Fix By: Brad House (@bradh352) - [Brad House brought this change] its not 1991 anymore, lower default timeout and retry count (#542) A lot of time has passed since the original timeouts and retry counts were chosen.

This PR changes the per-server timeout to 2s and the retry count lowered from 4 to 3. Fix By: Brad House (@bradh352) - [Brad House brought this change] Modernization: Implement base data-structures and replace usage (#540) c-ares currently lacks modern data structures that can make coding easier and more efficient. This PR implements a new linked list, skip list (sorted linked list), and hashtable implementation that are easy to use and hard to misuse. Though these implementations use more memory allocations than the prior implementation, the ability to more rapidly iterate on the codebase is a bigger win than any marginal performance difference (which is unlikely to be visible, modern systems are much more powerful than when c-ares was initially created). The data structure implementation favors readability and audit-ability over performance, however using the algorithmically correct data type for the purpose should offset any perceived losses. The primary motivation for this PR is to facilitate future implementation for Issues #444, #135, #458, and possibly #301 A couple additional notes: The ares_timeout() function is now O(1) complexity instead of O(n) due to the use of a skiplist. Some obscure bugs were uncovered which were actually being incorrectly validated in the test cases. These have been addressed in this PR but are not explicitly discussed.

However, because the terminating NUL byte was not checked in the substrings when comparing for uniqueness, the function would sometimes drop domains it should not. For example, ares_strsplit("example.com, example.co", ",") would only result in a single domain "example.com". Aside from this bugfix, the following cleanup is performed: 1. The tokenization now happens with the help of strcspn instead of the custom function is_delim. 2. The function list_contains has been inlined. 3. The interface of ares_strsplit has been simplified by removing the parameter make_set since in practice it was always 1. 4. There are fewer passes over the input string. 5. We resize the table using realloc() down to its minimum size. 6. The docstring of ares_strsplit is updated and also a couple typos are fixed. There occurs a single use of ares_strsplit and since the make_set parameter has been removed, the call in ares_init.c is modified accordingly. The unit test for ares_strsplit is also updated.

Vista was released in January 2007, and was EOL'd in 2017, and support for Vista is still maintained with this patch set. XP was EOL'd in Apr 8 2014. I believe the last OS based on something earlier than Vista was POSReady 2009, as it was XP based for some reason, and that was EOL'd in January 2019. Considering any POS system falls under the PCI-DSS rules, they aren't allow to run POSReady 2009 any more so there is no reason to try to continue supporting such systems.

Next, when AF_UNSPEC is specified, it properly handles search lists instead of first searching all of AF_INET6 then AF_INET, since ares_gethostbyname() searches in parallel. Therefore, this PR should also resolve the issues attempted in #94. A few things this PR does: 1. ares_parse_a_reply() and ares_parse_aaaa_reply() had very similar code to translate struct ares_addrinfo into a struct hostent as well as into struct ares_addrttl/ares_addr6ttl this has been split out into helper functions of ares__addrinfo2hostent() and ares__addrinfo2addrttl() to prevent this duplicative code. 2. ares_getaddrinfo() was apparently never honoring HOSTALIASES, and this was discovered once ares_gethostbyname() was turned into a wrapper, the affected test cases started failing. 3. A slight API modification to save the query hostname into struct ares_addrinfo as the last element of name. Since this is the last element, and all user-level instances of struct ares_addrinfo are allocated internally by c-ares, this is not an ABI-breaking change nor would it impact any API compatibility. This was needed since struct hostent has an h_name element. 4. Test Framework: MockServer tests via TCP would fail if more than 1 request was received at a time which is common when ares_getaddrinfo() queries for both A and AAAA records simultaneously. Infact, this was a long standing issue in which the ares_getaddrinfo() test were bypassing TCP alltogether. This has been corrected, the message is now processed in a loop. 5. Some tests had to be updated for overall correctness as they were invalid but somehow passing prior to this change.

In a mailing list post, @bradh352 agreed and suggested that I file a PR to make it so. This moves the blacklist check from being Windows-specific to being a general feature of config_nameservers(), no matter the nameserver source. It also simplifies the ares_ipv6_server_blacklisted() implementation to not parse and re-parse the blacklisted IPv6 addresses from strings on every check. I think they're almost as easy to read as a sequence of hex bytes in an array initializer, and it's definitely less work on each trip through the code.

Half of the changes are in Windows-specific code, and the other half should be safe no matter the compiler or OS. The allocation function change is probably the only one that needs explanation. MSVC gives warnings about the function pointers not being stable across DLL boundaries or something to that effect, so for Windows, I've made them be called indirectly, which at least made the compiler happy. I can't say I've tested every linking combination on Windows with them before or after the change, but it seems harmless.

When c-ares sends a DNS query, it computes the timeout for that request as follows: timeplus = channel->timeout << (query->try_count / channel->nservers); timeplus = (timeplus * (9 + (rand () & 7))) / 16; I see two issues with this code. Firstly, when either try_count or channel->timeout are large enough, this can end up as an illegal shift. Secondly, the algorithm for adding the random timeout (added in 2009) is surprising. The original commit that introduced this algorithm says it was done to avoid a "packet storm". But, the algorithm appears to only reduce the timeout by an amount proportional to the scaled timeout's magnitude. It isn't clear to me that, for example, cutting a 30 second timeout almost in half to roughly 17 seconds is appropriate. Even with the default timeout of 5000 ms, this algorithm computes values between 2812 ms and 5000 ms, which is enough to cause a slightly latent DNS response to get spuriously dropped. If preventing the timers from all expiring at the same time really is desirable, then it seems better to extend the timeout by a small factor so that the application gets at least the timeout it asked for, and maybe a little more. In my experience, this is common practice for timeouts: applications expect that a timeout will happen at or after the designated time (but not before), allowing for delay in detecting and reporting the timeout. Furthermore, it seems like the timeout shouldn't be extended by very much (we don't want a 30 second timeout changing into a 45 second timeout, either). Consider also the documentation of channel->timeout in ares_init_options(): The number of milliseconds each name server is given to respond to a query on the first try. (After the first try, the timeout algorithm becomes more complicated, but scales linearly with the value of timeout.) The default is five seconds. In the current implementation, even the first try does not use the value that the user supplies; it will use anywhere between 56% and 100% of that value. The attached patch attempts to address all of these concerns without trying to make the algorithm much more sophisticated. After performing a safe shift, this patch simply adds a small random timeout to the computed value of between 0 ms and 511 ms. I could see limiting the random amount to be no greater than a proportion of the configured magnitude, but I can't see scaling the random with the overall computed timeout. As far as I understand, the goal is just to schedule retries "not at the same exact time", so a small difference seems sufficient. UPDATE: randomization removed.

(#148) As of Android 8 (Oreo) access to net.dns# has been removed (https://developer.android.com/about/versions/oreo/android-8.0-changes.html). The reasoning given is that it, "improves privacy on the platform". Currently c-ares uses this to get the list of DNS servers. Now the only way to access the DNS server list is by using the Connectivity Manager though Java. This adds the necessary JNI code to use the Connectivity Manager and pull the DNS server list. The old way using __system_property_get with net.dns# remains for compatibilty. Using the Connectivity Manager requires the ACCESS_NETWORK_STATE permission to be set on the app. Existing applications most likely are not setting this and keeping the previous method as a fallback will at the very least ensure those apps don't break on older versions of Android. They will need to add this permission for Android 8 compatibility. Included in the patch are two initalization functions which are required. The JVM must be registered as well as the Connectivity Manager itself. There is no way to get the Connectivity Manager except though Java. Either being passed down to C directly or by passing in an Android Context which can be used to get the Connectivity Manager. Examples are provided in the documentation. - [Konstantinos Sofokleous brought this change] allow linking against the static msvc runtime library (#133) allow linking against the static msvc runtime library - [Gergely Nagy brought this change] Force using the ANSI versions of WinAPI functions (#142) When compiling c-ares with a build system that defines UNICODE, bad versions of WinAPI functions are used causing failures or even crashes.

David Drysdale (14 Mar 2017) - [Michael Osei brought this change] Update msvc_ver.inc (#91) For Visual Studio 2017 builds Daniel Stenberg (13 Mar 2017) - [Brad House brought this change] Windows DNS server sorting (#81) Original Patch From Brad Spencer: https://c-ares.haxx.se/mail/c-ares-archive-2016-04/0000.shtml My modifications include: * Dynamically find GetBestRoute2 since it is a Windows Vista+ symbol, and will fall back to prior behavior when not available. * Prefer get_DNS_AdaptersAddresses as the modifications should alleviate the concerns which caused us to prefer get_DNS_NetworkParams * Update AppVeyor to use MinGW-w64 instead of the legacy MinGW * Fix compile error in test suite for Windows. Original message from patch below: From: Brad Spencer Date: Fri, 29 Apr 2016 14:26:23 -0300 On Windows, the c-ares DNS resolver tries first to get a full list of DNS server addresses by enumerating the system's IPv4/v6 interfaces and then getting the per-interface DNS server lists from those interfaces and joining them together. The OS, at least in the way the c-ares prefers to query them (which also may be the only or best way in some environments), does not provide a unified list of DNS servers ordered according to "current network conditions". Currently, c-ares will then try to use them in whatever order the nested enumeration produces, which may result in DNS requests being sent to servers on one interface (hosting the current default route, for example) that are only intended to be used via another interface (intended to be used when the first interface is not available, for example). This, in turn, can lead to spurious failures and timeouts simply because of the server address order that resulted because of the enumeration process. This patch makes the (safe?) assumption that there is no other better rule to chose which interface's DNS server list should be prioritized. After all, a DNS lookup isn't something "per network"; applications don't look up "these DNS names on this interface and those DNS names on that interface". There is a single resource pool of DNS servers and the application should presume that any server will give it the "right" answer. However, even if all DNS servers are assumed to give equally useful responses, it is reasonable to expect that some DNS servers will not accept requests on all interfaces. This patch avoids the problem by sorting the DNS server addresses using the Windows IPv4/v6 routing tables. For example, a request to DNS server C on interface 2 that is actually sent over interface 1 (which may happen to have the default route) may be rejected by or not delivered to DNS server C. So, better to use DNS servers A and B associated with interface 1, at least as a first try. By using the metric of the route to the DNS server itself as a proxy for priority of the DNS server in the list, this patch is able to adapt dynamically to changes in the interface list, the DNS server lists per interface, which interfaces are active, the routing table, and so on, while always picking a good "best" DNS server first. In cases where any DNS server on any interface will do, this patch still seems useful because it will prioritize a lower-metric route's (and thus interface's) servers.

The patch does not modify any source files, it only adds 3 new files (CMakelists.txt, ares_build.h.cmake, ares_config.h.cmake) which form the build system. I've tried to go through as much of the autotools tests and extracted what I thought was appropriate, though many of the tests aren't as in-depth in CMake as they are for autotools ... it is unclear why some of them exist at all, I'm guessing for legacy systems that CMake probably doesn't support anyhow. Building the library, and examples (adig, ahost, acountry) plus installation should work across a large number of tested platforms. The tests have not yet been integrated.

David Drysdale (24 Sep 2016) - api: add ARES_OPT_NOROTATE optmask value Fix up a couple of problems with configuring whether c-ares rotates between different name servers between requests. Firstly, ares_save_options() returns (in *optmask) the value of (channel->optmask & ARES_OPT_ROTATE), which doesn't necessarily indicate whether the channel is or is not actually doing rotation. This can be confusing/incorrect if: - the channel was originally configured without ARES_OPT_ROTATE (so it appears that the channel is not rotating) - the /etc/resolv.conf file includes the 'rotate' option (so the channel is actually performing rotation). Secondly, it is not possible to reliably configure a channel to not-rotate; leaving off ARES_OPT_ROTATE is not enough, since a 'rotate' option in /etc/resolv.conf will turn it on again. Therefore: - add an ARES_OPT_NOROTATE optmask value to allow explicit configuration of no-rotate behaviour - in ares_save_options(), report the value of channel->rotate as exactly one of (optmask & ARES_OPT_ROTATE) or (optmask & ARES_OPT_NOROTATE). In terms of back-compatibility: - existing apps that set ARES_OPT_ROTATE will continue to rotate, and to have ARES_OPT_ROTATE reported back from ares_save_options() - existing apps that don't set ARES_OPT_ROTATE will continue to use local config/defaults to decide whether to rotate, and will now get ARES_OPT_ROTATE or ARES_OPT_NOROTATE reported back from ares_save_options() rather than 0. - ares_init_options: only propagate init failures from options Commit 46bb820be3a8 ("ares_init_options: don't lose init failure") changed init behaviour so that earlier errors in initialization weren't lost. In particular, if the user passes in specific options but they are not applied (e.g. because of an allocation failure), that failure needs to be reported back to the user; this also applies when duplicating a channel with ares_dup(). However, other initialization failures can be ignored and overridden -- in particular, if init_by_resolv_conf() or init_by_environment() fail, then falling back to default values is OK. So only preserve failures from the init_by_options() stage, not from all initialization stages. Fixes issue 60. - test: Force reinstall of libtool on OSX Travis build environment appears to have changed. - test: Add valgrind build variant - test: Add null pointer to gtest args GoogleTest assumes that there is a null pointer in argv[argc], so make it look like that.

This is much (e.g. 10x) faster. Add code to support this, by checking whether __AFL_LOOP is defined at compile-time. Also, shift the code to effectively be C rather than C++. - test: simplify deps for fuzzer entrypoint No need to depend on the rest of the test code (ares-test.h) for the fuzzer entrypoint; this makes the entrypoint slightly simpler to build with LLVM's libFuzzer. Also shift the code to effectively be C rather than C++ - test: disable MinGW tests The test binary built in the MinGW build is failing for some reason. It works for me when I build locally, so I'm guessing it's down to some sort of AppVeyor environment issue. Disable for now.

Daniel Stenberg (9 Mar 2016) - [Brad House brought this change] configure: check if tests can get built before enabled The current approach for disabling tests is not a good solution because it forces you to pass --disable-tests, rather than auto-detect if your system can support the tests in the first place. Many (most?) systems do not have C++11. This also causes issues when chain-building c-ares, the hosting system needs to be updated to support passing this additional flag if necessary, it doesn't seem reasonable to add this requirement which breaks compatibility. This change auto-detects if the system can build the tests and automatically disable them if it cannot. If you pass --enable-tests to configure and the system cannot build them either due to lack of system support, or because cross-compilation is being used, it will throw an appropriate error since the user indicated they really did want the tests.

This has exposed a previously unknown bug in `lookups` initialization code. If there is no lookup configuration in `resolv.conf`, `init_by_resolv_conf` will attempt to read it from other files available on the system. However, some of these files may have restricted permissions (like `600`), which will lead to `EACCESS` errno, which in turn is handled like a fatal error by `init_by_resolv_conf`. However, it sounds illogical that this error should be handled as a fatal. There is a `init_by_defaults` call that overrides `lookups` with default value, and certainly possible absence of lookup information is the reason why this function exists in a first place! I suggest handling any `fopen` errors as non-fatal ones, allowing to pick up the `lookups` value from different config files, or to pick up default value.

Also cope with ECONNREFUSED as well as ENOTFOUND. - test: Get test code building under Windows - Initial nmake file based off library nmake file - Cast socket call arguments to (char *) - Use wrapper sclose() that maps to closesocket() or close() - Build a config.h indicating presence of headers - Conditionally include netdb.h - Remove unnecessary include of sys/socket.h - Force longer bitmask for allocation failure tracking - Call WSAStartup() / WSACleanup() in main() - Set TCP_NODELAY for mock server - Turn on tests in AppVeyor build - test: Disable tests that manipulate env on Windows - test: Move file lists into Makefile.inc In preparation for a Win32 build of the test suite. - test: Add a simple multi-server test Check rotate option does something - test: Allow for multiple mock servers - Update the MockServer to allow separate specification of UDP and TCP ports - Have an array of mock servers listening on consecutive sets of ports. - Rename Process(fd) to ProcessFD(fd) to avoid confusion. - Initialize channel by using the new ares_set_servers_ports() entrypoint, so multiple ports on the same loopback address can be used. - test: Update test for set/get_servers variants Ports are significant in the _ports_ variant functions, so update test to cope. - test: Make GetNameServers() utility function port-aware Also make it generally available. - test: more testing, including of internal static functions - test: more tests, especially fallback processing - Make mock server listen on UDP + TCP in parallel. - Test UDP->TCP fallback on truncation - Test EDNS->no-EDNS fallback - Test some environment init options - Test nonsense reply test: short response - test: more tests, particularly of initialization - test: Run mock tests over both TCP and UDP With the exception of a few tests that make use of the timed retry aspect of UDP. - test: Run mock tests over both IPv4 and IPv6 - test: Add more tests for edge cases - test: more nooks and crannies of pton functions - test: More tests for PTR parsing - test: Use of HOSTALIAS environment variable - test: Add RAII utility classes for testing - TempFile holds specific contents - EnvValue sets an environment variable - test: More search domain scenarios - test: Remove duplicate flags from Makefile.am - test: Make test code leak-free - test: More tests - test use of sortlist - test gethostbyname(AF_UNSPEC) - test: Test ares_gethostbyname_file() - test: Add more tests of ares_getnameinfo() - test: Tweak tests, add alloc failure test - test: Test init with options - test: More tests - ares_inet_net_pton() variants - ares_getsock() variants - test: Expose ProcessWork() function - test: More parsing tests Including: - Split each parse function test set out into separate files. - Add an allocation failure test for each parsing function. - Add error check test for each parsing function. - test: Add various additional tests - test: More tests Include tests of internal functions, based on the value of the CARES_SYMBOL_HIDING macro; need to configure the library with --disable-symbol-hiding to enable these tests. - test: Allow command line override of mock server port - test: Add README.md documentation - test: Temporarily avoid latest Python requests package Currently get error from Travis on this install step, and downgrading one version appears to fix the problem. "Could not find any downloads that satisfy the requirement pyOpenSSL>=0.13 (from requests[security])" - test: Add AppVeyor config file for Windows build - test: Add configuration for a Travis build Cover Linux & OSX on the container infrastructure, but install a later G++ to satisfy the tests' need for C++11. Use a build matrix to include a variety of build variants: - ASAN - UBSAN - LSAN - Coverage via coveralls.io test: invoke ASAN and coverage in Travis build Also shift to use explicit build matrix test: Use coveralls.io for coverage tracking test: Add a build with UBSAN Also expand and re-order the setting of environment variables for easier modification. test: Add LSAN build to Travis config - test: Add initial unit tests for c-ares library The tests are written in C++11, using the GoogleTest and GoogleMock frameworks. They have their own independent autoconf setup, so that users of the library need not have a C++ compiler just to get c-ares working (however, the test/configure.ac file does assume the use of a shared top-level m4/ directory). However, this autoconf setup has only been tested on Linux and OSX so far. Run with "./arestest", or "./arestest -v" to see extra debug info. The GoogleTest options for running specific tests are also available (e.g. "./arestest --gtest_filter=*Live*"). The tests are nowhere near complete yet (currently hitting around 60% coverage as reported by gcov), but they do include examples of a few different styles of testing: - There are live tests (ares-test-live.cc), which assume that the current machine has a valid DNS setup and connection to the internet; these tests issue queries for real domains but don't particularly check what gets returned. The tests will fail on an offline machine. - There a few mock tests (ares-test-mock.cc) that set up a fake DNS server and inject its port into the c-ares library configuration. These tests allow specific response messages to be crafted and injected, and so are likely to be used for many more tests in future. - To make this generation/injection easier, the dns-proto.h file includes C++ helper classes for building DNS packets. - Other library entrypoints that don't require network activity (e.g. ares_parse_*_reply) are tested directly. - There are few tests of library-internal functions that are not normally visible to API users (in ares-test-internal.cc). - A couple of the tests use a helper method of the test fixture to inject memory allocation failures, using the earlier change to the library to allow override of malloc/realloc/free. - There is also an entrypoint to allow Clang's libfuzzer to drive the packet parsing code in ares_parse_*_reply, together with a standalone wrapper for it (./aresfuzz) to allow use of afl-fuzz for further fuzz testing. - test: Add local copy of GoogleMock/GoogleTest 1.7.0 Don't check in gtest/m4 files, as they are unused and interfere with the top-level configure process. - doc: Show build badges in README.md Note that these URLs will need to be updated if/when the test branch gets pulled into the master repo/branch. - doc: Convert README to README.md Gives better display on GitHub - doc: Update in preparation for next release Assume 1.11.0 is next (as there are various API additions). Also add myself to AUTHORS. - build: Allow header compilation by Windows C++ compiler - build: Expose whether symbol hiding is on Adding the CARES_SYMBOL_HIDING definition allows the test suite to detect whether internal symbols are available or not. - build: Add autoconf macros for C++11 code using pthreads Pull in testing macros from the GNU autoconf archive to allow configure scripts to test for and setup use of a C++11 compiler (AX_CXX_COMPILE_STDCXX_11) and the pthreads library (AX_PTHREAD). Note that these macros are not used by the main library autoconf, just by the tests (which share the same m4/ directory). - build: Add a code coverage option Configure with: ./configure --enable-code-coverage Show coverage output with: make code-coverage-capture Built on m4/ax_code_coverage.m4 from the GNU autoconf archive to provide the macros to check for presence of gcov + lcov; upstream macro modified to: - Remove use of $(AM_DEFAULT_VERBOSITY) , as earlier versions of autoconf (such as the one used by default on Travis) do not have this. - Rather than automatically defining CODE_COVERAGE_RULES to be a set of makefile rules that use ifeq/endif (which is GNU make-specific), instead only define CODE_COVERAGE_RULES if coverages is turned on, and in that case don't use conditionals in the makefile. - api: Add entrypoints to allow use of per-server ports Add user-visible entrypoints ares_{get,set}_servers_ports(3), which take struct ares_addr_port_node rather than struct ares_addr_node. This structure includes a UDP and TCP port number; if this is set to zero, the channel-wide port values are used as before. Similarly, add a new ares_set_servers_ports_csv(3) entrypoint, which is analogous to ares_set_servers(3) except it doesn't ignore any specified port information; instead, any per-server specified port is used as both the UDP and TCP port for that server. The internal struct ares_addr is extended to hold the UDP/TCP ports, stored in network order, with the convention that a value of zero indicates that the channel-wide UDP/TCP port should be used. For the internal implementation of ares_dup(3), shift to use the _ports() version of the get/set functions, so port information is transferred correctly to the new channel. Update manpages, and add missing ares_set_servers_csv to the lists while we're at it - api: Add ares_set_sortlist(3) entrypoint Allow explicit configuration of the channel's sortlist, by specifying a string in the same format as the equivalent /etc/resolv.conf option. This allows library users to perform the same configuration that is available via /etc/resolv.conf, but without needing to change that file. - api: Allow injection of user-specified malloc/free functions Add a new ares_library_init_mem() initialization function for the library which allows the library user to specify their own malloc, realloc & free equivalents for use library-wide. Store these function pointers in library-wide global variables, defaulting to libc's malloc(), realloc() and free(). Change all calls to malloc, realloc and free to use the function pointer instead. Also ensure that ares_strdup() is always available (even if the local environment includes strdup(3)), and change the library code to always use it. Convert calls to calloc() to use ares_malloc() + memset - api: Add option to expose some internal functions Purely for testing, add --enable-expose-statics option to configure which converts some static internal functions to be externally visible. - api: Expose the ares_library_initialized() function - ahost: Allow repeated -s options This also removes a potential leak where later -s options would replace earlier ones without freeing the relevant string. - Mark unhittable lines Add comments for the benefit of the lcov tool, marking lines that cannot be hit. Typically these are fall-back protection arms that are already covered by earlier checks, and so it's not worth taking out the unhittable code (in case someone changes the code between the two places in future). - ares_set_servers_csv.3: make return type match code - bitncmp: update comment to match code behaviour - ares_striendstr: fix so non-NULL return can happen This looks to have been broken since it was first introduced in 2005 in commit aba0b775ea30 ("Added ares_getnameinfo which mimics the getnameinfo API") - config_sortlist: free any existing sortlist on (re)alloc failure If we get an allocation failure on 2nd or later entry in the sortlist, the code would return ENOMEM but still leave the initial entries allocated. Ensure that *sortlist is set to NULL whenever ENOMEM is returned. - ares_dup: clear new channel on failure If the attempt to transfer IPv6 servers from the old to the new channel fails, the previous code would still return a channel to the user even though an error return code was generated. This makes it likely that users would leak the channel, so explicitly clear the channel in this case. - ares_init_options: don't lose init failure If (say) init_by_options() fails, the subsequent call to init_by_defaults() was overwriting the return code with success. Still call init_by_defaults() regardless, but track its return value separately - ares_gethostbyname: don't leak valid-but-empty hostent If an AF_UNSPEC query gets a valid response to its AAAA query, but which has no IPv6 addresses in it, then the code chains on to a A record query. However, the hostent from the AAAA response was being leaked along the way (because it gets replaced before the follow-on end_hquery() invocation). - ares_parse_txt_reply: propagate errors from per-substring loop If we get an allocation failure when processing a particular substring in a TXT record, that failure is silently lost; fix that by propagating errors from the inner loop to the outer loop. - process_answer: fix things up correctly when removing EDNS option When a server rejects an EDNS-equipped request, we retry without the EDNS option. However, in TCP mode, the 2-byte length prefix was being calculated wrong -- it was built from the answer length rather than the length of the original request. Also, it is theoretically possible that the call to realloc() might change the data pointed to; to allow for this, qbuf also needs updating. (Both these fixes were actually included in a patchset sent on the mailing list in Oct 2012, but were included with other functional changes that didn't get merged: http://c-ares.haxx.se/mail/c-ares-archive-2012-10/0004.shtml) - ares__read_line: clear buf pointer on realloc failure - ares_expand_name: check for valid bits in label length The top two bits of the label length indicate whether this is a label length (00) or an index to a name elsewhere in the message (11). RFC1035 4.1.4 says that the other possible values for the top two bits (01, 10) are reserved for future use.

Daniel Stenberg decided to fork and release a separate project since the original ares author didn't want the improvements that were vital for our use of it. This package is dubbed 'c-ares' since Daniel wanted this for use within the curl project (hence the letter C) and it makes a nice pun. c-ares is not API compatible with ares: a new name makes that more obvious to the public. The original libares was distributed at ftp://athena-dist.mit.edu:pub/ATHENA/ares (which seems to not be alive anymore). A local copy of the original ares package is kept here: https://c-ares.org/download/ares-1.1.1.tar.gz c-ares-1.27.0/CMakeLists.txt0000644000175000017500000010676414566044053011221 # Copyright (C) The c-ares project and its contributors # SPDX-License-Identifier: MIT CMAKE_MINIMUM_REQUIRED (VERSION 3.5.0) list(APPEND CMAKE_MODULE_PATH "${CMAKE_CURRENT_SOURCE_DIR}/cmake/") INCLUDE (CheckIncludeFiles) INCLUDE (CheckTypeSize) INCLUDE (CheckFunctionExists) INCLUDE (CheckSymbolExists) INCLUDE (CheckCSourceCompiles) INCLUDE (CheckStructHasMember) INCLUDE (CheckLibraryExists) PROJECT (c-ares LANGUAGES C VERSION "1.27.0" ) # Set this version before release SET (CARES_VERSION "1.27.0") INCLUDE (GNUInstallDirs) # include this *AFTER* PROJECT(), otherwise paths are wrong. # This is for libtool compatibility, and specified in a form that is easily # translatable from libtool (even if the actual form doesn't make sense). # For instance, in an autotools project, in Makefile.am there is a line that # contains something like: # -version-info 4:0:2 # This breaks down into sections of current:revision:age # This then generates a version of "(current-age).age.revision" with an # interface version of "(current-age)" # For example, a version of 4:0:2 would generate output such as: # libname.so -> libname.so.2 # libname.so.2 -> libname.so.2.2.0 SET (CARES_LIB_VERSIONINFO "14:0:12") OPTION (CARES_STATIC "Build as a static library" OFF) OPTION (CARES_SHARED "Build as a shared library" ON) OPTION (CARES_INSTALL "Create installation targets (chain builders may want to disable this)" ON) OPTION (CARES_STATIC_PIC "Build the static library as PIC (position independent)" OFF) OPTION (CARES_BUILD_TESTS "Build and run tests" OFF) OPTION (CARES_BUILD_CONTAINER_TESTS "Build and run container tests (implies CARES_BUILD_TESTS, Linux only)" OFF) OPTION (CARES_BUILD_TOOLS "Build tools" ON) OPTION (CARES_SYMBOL_HIDING "Hide private symbols in shared libraries" OFF) OPTION (CARES_THREADS "Build with thread-safety support" ON) SET (CARES_RANDOM_FILE "/dev/urandom" CACHE STRING "Suitable File / Device Path for entropy, such as /dev/urandom") # Tests require a C++14 compiler IF (CARES_BUILD_TESTS OR CARES_BUILD_CONTAINER_TESTS) set(CMAKE_CXX_STANDARD 14) set(CMAKE_CXX_STANDARD_REQUIRED TRUE) set(CMAKE_CXX_EXTENSIONS FALSE) enable_language(CXX) ENDIF () # Tests require static to be enabled on Windows to be able to access otherwise hidden symbols IF ((CARES_BUILD_TESTS OR CARES_BUILD_CONTAINER_TESTS) AND (NOT CARES_STATIC) AND WIN32) SET (CARES_STATIC ON) SET (CARES_STATIC_PIC ON) MESSAGE (WARNING "Static building was requested be disabled, but re-enabled to support tests") ENDIF () INCLUDE (EnableWarnings) # allow linking against the static runtime library in msvc IF (MSVC) OPTION (CARES_MSVC_STATIC_RUNTIME "Link against the static runtime library" OFF) IF (CARES_MSVC_STATIC_RUNTIME) # CMAKE_CONFIGURATION_TYPES is empty on non-IDE generators (Ninja, NMake) # and that's why we also use CMAKE_BUILD_TYPE to cover for those generators. # For IDE generators, CMAKE_BUILD_TYPE is usually empty FOREACH (config_type ${CMAKE_CONFIGURATION_TYPES} ${CMAKE_BUILD_TYPE}) STRING (TOUPPER ${config_type} upper_config_type) SET (flag_var "CMAKE_C_FLAGS_${upper_config_type}") IF (${flag_var} MATCHES "/MD") STRING (REGEX REPLACE "/MD" "/MT" ${flag_var} "${${flag_var}}") ENDIF () ENDFOREACH () # clean up SET (upper_config_type) SET (config_type) SET (flag_var) ENDIF () ENDIF () IF (CARES_SYMBOL_HIDING) IF (CMAKE_VERSION VERSION_LESS 3.12) MESSAGE (FATAL_ERROR "Hiding symbols requires CMake 3.12") ENDIF () CMAKE_POLICY (SET CMP0063 NEW) ENDIF () # Keep build organized, but only if it is the top-level project. # CMake 3.21 or later has PROJECT_IS_TOP_LEVEL, but we aren't yet depending on # that version.

Also add rules using AX_ADD_AM_MACRO_STATIC; and # $enable_code_coverage which can be used in subsequent configure output. # CODE_COVERAGE_ENABLED is defined and substituted, and corresponds to the # value of the --enable-code-coverage option, which defaults to being # disabled. # # Test also for gcov program and create GCOV variable that could be # substituted. # # Note that all optimization flags in CFLAGS must be disabled when code # coverage is enabled. # # Usage example: # # configure.ac: # # AX_CODE_COVERAGE # # Makefile.am: # # include $(top_srcdir)/aminclude_static.am # # my_program_LIBS = ... $(CODE_COVERAGE_LIBS) ... # my_program_CPPFLAGS = ... $(CODE_COVERAGE_CPPFLAGS) ... # my_program_CFLAGS = ... $(CODE_COVERAGE_CFLAGS) ... # my_program_CXXFLAGS = ... $(CODE_COVERAGE_CXXFLAGS) ... # # clean-local: code-coverage-clean # distclean-local: code-coverage-dist-clean # # This results in a "check-code-coverage" rule being added to any # Makefile.am which do "include $(top_srcdir)/aminclude_static.am" # (assuming the module has been configured with --enable-code-coverage). # Running `make check-code-coverage` in that directory will run the # module's test suite (`make check`) and build a code coverage report # detailing the code which was touched, then print the URI for the report. # # This code was derived from Makefile.decl in GLib, originally licensed # under LGPLv2.1+. # # LICENSE # # Copyright (c) 2012, 2016 Philip Withnall # Copyright (c) 2012 Xan Lopez # Copyright (c) 2012 Christian Persch # Copyright (c) 2012 Paolo Borelli # Copyright (c) 2012 Dan Winship # Copyright (c) 2015,2018 Bastien ROUCARIES # # This library is free software; you can redistribute it and/or modify it # under the terms of the GNU Lesser General Public License as published by # the Free Software Foundation; either version 2.1 of the License, or (at # your option) any later version. # # This library is distributed in the hope that it will be useful, but # WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

It # sets the PTHREAD_LIBS output variable to the threads library and linker # flags, and the PTHREAD_CFLAGS output variable to any special C compiler # flags that are needed. (The user can also force certain compiler # flags/libs to be tested by setting these environment variables.) # # Also sets PTHREAD_CC and PTHREAD_CXX to any special C compiler that is # needed for multi-threaded programs (defaults to the value of CC # respectively CXX otherwise). (This is necessary on e.g. AIX to use the # special cc_r/CC_r compiler alias.) # # NOTE: You are assumed to not only compile your program with these flags, # but also to link with them as well. For example, you might link with # $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS # $PTHREAD_CXX $CXXFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS # # If you are only building threaded programs, you may wish to use these # variables in your default LIBS, CFLAGS, and CC: # # LIBS="$PTHREAD_LIBS $LIBS" # CFLAGS="$CFLAGS $PTHREAD_CFLAGS" # CXXFLAGS="$CXXFLAGS $PTHREAD_CFLAGS" # CC="$PTHREAD_CC" # CXX="$PTHREAD_CXX" # # In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant # has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to # that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX). # # Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the # PTHREAD_PRIO_INHERIT symbol is defined when compiling with # PTHREAD_CFLAGS. # # ACTION-IF-FOUND is a list of shell commands to run if a threads library # is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it # is not found. If ACTION-IF-FOUND is not specified, the default action # will define HAVE_PTHREAD. # # Please let the authors know if this macro fails on any platform, or if # you have any other suggestions or comments. This macro was based on work # by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help # from M. Frigo), as well as ac_pthread and hb_pthread macros posted by # Alejandro Forero Cuervo to the autoconf macro repository. We are also # grateful for the helpful feedback of numerous users. # # Updated for Autoconf 2.68 by Daniel Richard G. # # LICENSE # # Copyright (c) 2008 Steven G.

This tends not # to be the way of modern systems, but it's conceivable.) # (Note 2: On some systems, notably Darwin, -pthread is not needed # to get POSIX threads support; the API is always present and # active. We could reasonably leave PTHREAD_CFLAGS empty. But # -pthread does define _REENTRANT, and while the Darwin headers # ignore this macro, third-party headers might not.) # However, older versions of Clang make a point of warning the user # that, in an invocation where only linking and no compilation is # taking place, the -pthread option has no effect ("argument unused # during compilation").

Major changes in release 1.1.0: * Added ares_free_string() function so that memory can be freed in the same layer as it is allocated, a desirable feature in some environments. * A few of the ares_dns.h macros are fixed to use the proper bitwise operator. * Fixed a couple of fenceposts fixed in ares_expand_name()'s bounds-checking. * In process_timeouts(), extract query->next before calling next_server() and possibly freeing the query structure. * Casted arguments to ctype macros casted to unsigned char, since not all char values are valid inputs to those macros according to ANSI. c-ares-1.27.0/LICENSE.md0000644000175000017500000000231414530123235010036 # c-ares license MIT License Copyright (c) 1998 Massachusetts Institute of Technology Copyright (c) 2007 - 2023 Daniel Stenberg with many contributors, see AUTHORS file.

This document does not describe how to install c-ares using such a binary package. This document describes how to compile, build and install c-ares from source code. Building from Git ================= If you get your code off a Git repository rather than an official release tarball, see the [GIT-INFO](GIT-INFO) file in the root directory for specific instructions on how to proceed. In particular, if not using CMake you will need to run `./buildconf` (Unix) or `buildconf.bat` (Windows) to generate build files, and for the former you will need a local installation of Autotools. If using CMake the steps are the same for both Git and official release tarballs. AutoTools Build =============== ### General Information, works on most Unix Platforms (Linux, FreeBSD, etc.) A normal Unix installation is made in three or four steps (after you've unpacked the source archive): ./configure make make install You probably need to be root when doing the last command. If you have checked out the sources from the git repository, read the [GIT-INFO](GIT_INFO) on how to proceed. Get a full listing of all available configure options by invoking it like: ./configure --help If you want to install c-ares in a different file hierarchy than /usr/local, you need to specify that already when running configure: ./configure --prefix=/path/to/c-ares/tree If you happen to have write permission in that directory, you can do `make install` without being root. An example of this would be to make a local installation in your own home directory: ./configure --prefix=$HOME make make install ### More Options To force configure to use the standard cc compiler if both cc and gcc are present, run configure like CC=cc ./configure # or env CC=cc ./configure To force a static library compile, disable the shared library creation by running configure like: ./configure --disable-shared If you're a c-ares developer and use gcc, you might want to enable more debug options with the `--enable-debug` option. ### Special Cases Some versions of uClibc require configuring with `CPPFLAGS=-D_GNU_SOURCE=1` to get correct large file support. The Open Watcom C compiler on Linux requires configuring with the variables: ./configure CC=owcc AR="$WATCOM/binl/wlib" AR_FLAGS=-q \ RANLIB=/bin/true STRIP="$WATCOM/binl/wstrip" CFLAGS=-Wextra ### CROSS COMPILE (This section was graciously brought to us by Jim Duey, with additions by Dan Fandrich) Download and unpack the c-ares package. `cd` to the new directory. (e.g. `cd c-ares-1.7.6`) Set environment variables to point to the cross-compile toolchain and call configure with any options you need. Be sure and specify the `--host` and `--build` parameters at configuration time. The following script is an example of cross-compiling for the IBM 405GP PowerPC processor using the toolchain from MonteVista for Hardhat Linux. ```sh #! /bin/sh export PATH=$PATH:/opt/hardhat/devkit/ppc/405/bin export CPPFLAGS="-I/opt/hardhat/devkit/ppc/405/target/usr/include" export AR=ppc_405-ar export AS=ppc_405-as export LD=ppc_405-ld export RANLIB=ppc_405-ranlib export CC=ppc_405-gcc export NM=ppc_405-nm ./configure --target=powerpc-hardhat-linux \ --host=powerpc-hardhat-linux \ --build=i586-pc-linux-gnu \ --prefix=/opt/hardhat/devkit/ppc/405/target/usr/local \ --exec-prefix=/usr/local ``` You may also need to provide a parameter like `--with-random=/dev/urandom` to configure as it cannot detect the presence of a random number generating device for a target system. The `--prefix` parameter specifies where c-ares will be installed. If `configure` completes successfully, do `make` and `make install` as usual. In some cases, you may be able to simplify the above commands to as little as: ./configure --host=ARCH-OS ### Cygwin (Windows) Almost identical to the unix installation. Run the configure script in the c-ares root with `sh configure`. Make sure you have the sh executable in `/bin/` or you'll see the configure fail toward the end. Run `make` ### QNX (This section was graciously brought to us by David Bentham) As QNX is targeted for resource constrained environments, the QNX headers set conservative limits. This includes the `FD_SETSIZE` macro, set by default to 32. Socket descriptors returned within the c-ares library may exceed this, resulting in memory faults/SIGSEGV crashes when passed into `select(..)` calls using `fd_set` macros. A good all-round solution to this is to override the default when building c-ares, by overriding `CFLAGS` during configure, example: # configure CFLAGS='-DFD_SETSIZE=64 -g -O2' ### RISC OS The library can be cross-compiled using gccsdk as follows: CC=riscos-gcc AR=riscos-ar RANLIB='riscos-ar -s' ./configure \ --host=arm-riscos-aof --without-random --disable-shared make where `riscos-gcc` and `riscos-ar` are links to the gccsdk tools. You can then link your program with `c-ares/lib/.libs/libcares.a`. ### Android Method using a configure cross-compile (tested with Android NDK r7b): - prepare the toolchain of the Android NDK for standalone use; this can be done by invoking the script: ./tools/make-standalone-toolchain.sh which creates a usual cross-compile toolchain. Let's assume that you put this toolchain below `/opt` then invoke configure with something like: ``` export PATH=/opt/arm-linux-androideabi-4.4.3/bin:$PATH ./configure --host=arm-linux-androideabi [more configure options] make ``` - if you want to compile directly from our GIT repo you might run into this issue with older automake stuff: ``` checking host system type... Invalid configuration `arm-linux-androideabi': system `androideabi' not recognized configure: error: /bin/sh ./config.sub arm-linux-androideabi failed ``` this issue can be fixed with using more recent versions of `config.sub` and `config.guess` which can be obtained here: http://git.savannah.gnu.org/gitweb/?p=config.git;a=tree you need to replace your system-own versions which usually can be found in your automake folder: `find /usr -name config.sub` CMake builds ============ Current releases of c-ares introduce a CMake v3+ build system that has been tested on most platforms including Windows, Linux, FreeBSD, macOS, AIX and Solaris. In the most basic form, building with CMake might look like: ```sh cd /path/to/cmake/source mkdir build cd build cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local/cares .. make sudo make install ``` Options ------- Options to CMake are passed on the command line using "-D${OPTION}=${VALUE}". The values defined are all boolean and take values like On, Off, True, False. | Option Name | Description | Default Value | |-----------------------------|-----------------------------------------------------------------------|----------------| | CARES_STATIC | Build the static library | Off | | CARES_SHARED | Build the shared library | On | | CARES_INSTALL | Hook in installation, useful to disable if chain building | On | | CARES_STATIC_PIC | Build the static library as position-independent | Off | | CARES_BUILD_TESTS | Build and run tests | Off | | CARES_BUILD_CONTAINER_TESTS | Build and run container tests (implies CARES_BUILD_TESTS, Linux only) | Off | | CARES_BUILD_TOOLS | Build tools | On | | CARES_SYMBOL_HIDING | Hide private symbols in shared libraries | Off | | CARES_THREADS | Build with thread-safety support | On | Ninja ----- Ninja is the next-generation build system meant for generators like CMake that heavily parallelize builds. Its use is very similar to the normal build: ```sh cd /path/to/cmake/source mkdir build cd build cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local/cares -G "Ninja" .. ninja sudo ninja install ``` Windows MSVC Command Line ------------------------- ``` cd \path\to\cmake\source mkdir build cd build cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=C:\cares -G "NMake Makefiles" .. nmake nmake install ``` Windows MinGW-w64 Command Line via MSYS --------------------------------------- ``` cd \path\to\cmake\source mkdir build cd build cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=C:\cares -G "MSYS Makefiles" .. make make install ``` Platform-specific build systems =============================== Win32 ----- ### Building Windows DLLs and C run-time (CRT) linkage issues As a general rule, building a DLL with static CRT linkage is highly discouraged, and intermixing CRTs in the same app is something to avoid at any cost. Reading and comprehension of the following Microsoft Learn article is a must for any Windows developer. Especially important is full understanding if you are not going to follow the advice given above. - [Use the C Run-Time](https://learn.microsoft.com/en-us/troubleshoot/developer/visualstudio/cpp/libraries/use-c-run-time) If your app is misbehaving in some strange way, or it is suffering from memory corruption, before asking for further help, please try first to rebuild every single library your app uses as well as your app using the debug multithreaded dynamic C runtime. ### MingW32 Make sure that MinGW32's bin dir is in the search path, for example: set PATH=c:\mingw32\bin;%PATH% then run 'make -f Makefile.m32' in the root dir. ### MSVC 6 caveats If you use MSVC 6 it is required that you use the February 2003 edition PSDK: http://www.microsoft.com/msdownload/platformsdk/sdkupdate/psdk-full.htm ### MSVC from command line Run the `vcvars32.bat` file to get a proper environment. The `vcvars32.bat` file is part of the Microsoft development environment and you may find it in `C:\Program Files\Microsoft Visual Studio\vc98\bin` provided that you installed Visual C/C++ 6 in the default directory. Further details in [README.msvc](README.msvc) ### Important static c-ares usage note When building an application that uses the static c-ares library, you must add `-DCARES_STATICLIB` to your `CFLAGS`. Otherwise the linker will look for dynamic import symbols. IBM OS/2 -------- Building under OS/2 is not much different from building under unix. You need: - emx 0.9d - GNU make - GNU patch - ksh - GNU bison - GNU file utilities - GNU sed - autoconf 2.13 If during the linking you get an error about `_errno` being an undefined symbol referenced from the text segment, you need to add `-D__ST_MT_ERRNO__` in your definitions. If you're getting huge binaries, probably your makefiles have the `-g` in `CFLAGS`. NetWare ------- To compile `libcares.a` / `libcares.lib` you need: - either any gcc / nlmconv, or CodeWarrior 7 PDK 4 or later. - gnu make and awk running on the platform you compile on; native Win32 versions can be downloaded from: http://www.gknw.net/development/prgtools/ - recent Novell LibC SDK available from: http://developer.novell.com/ndk/libc.htm - or recent Novell CLib SDK available from: http://developer.novell.com/ndk/clib.htm Set a search path to your compiler, linker and tools; on Linux make sure that the var `OSTYPE` contains the string 'linux'; set the var `NDKBASE` to point to the base of your Novell NDK; and then type `make -f Makefile.netware` from the top source directory; VCPKG ===== You can build and install c-ares using [vcpkg](https://github.com/Microsoft/vcpkg/) dependency manager: ```sh or powershell git clone https://github.com/Microsoft/vcpkg.git cd vcpkg ./bootstrap-vcpkg.sh ./vcpkg integrate install ./vcpkg install c-ares ``` The c-ares port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please [create an issue or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository. WATCOM ===== To build c-ares with OpenWatcom, you need to have at least version 1.9 of OpenWatcom. You can get the latest version from [http://openwatcom.org/ftp/install/](http://openwatcom.org/ftp/install/). Install the version that corresponds to your current host platform. After installing OpenWatcom, open a new command prompt and execute the following commands: ``` cd \path\to\cmake\source buildconf.bat wmake -u -f Makefile.Watcom ``` After running wmake, you should get adig.exe, ahost.exe, and the static and dynamic versions of libcares. PORTS ===== This is a probably incomplete list of known hardware and operating systems that c-ares has been compiled for.

To build the tests: - Build the main c-ares library first, in the directory above this. To enable tests of internal functions, configure the library build to expose hidden symbols with `./configure --disable-symbol-hiding`. - Generate a `configure` file by running `autoreconf -iv` (which requires a local installation of [autotools](https://www.gnu.org/software/automake/manual/html_node/Autotools-Introduction.html)). - `./configure` - `make` - Run the tests with `./arestest`, or `./arestest -v` for extra debug info. Points to note: - The tests are written in C++11, and so need a C++ compiler that supports this. To avoid adding this as a requirement for the library, the configuration and build of the tests is independent from the library. - The tests include some live queries, which will fail when run on a machine without internet connectivity. To skip live tests, run with `./arestest --gtest_filter=-*.Live*`. - The tests include queries of a mock DNS server. This server listens on port 5300 by default, but the port can be changed with the `-p 5300` option to `arestest`. Test Types ---------- The test suite includes various different types of test. - There are live tests (`ares-test-live.cc`), which assume that the current machine has a valid DNS setup and connection to the internet; these tests issue queries for real domains but don't particularly check what gets returned. The tests will fail on an offline machine. - There are some mock tests (`ares-test-mock.cc`) that set up a fake DNS server and inject its port into the c-ares library configuration. These tests allow specific response messages to be crafted and injected, and so are likely to be used for many more tests in future. - To make this generation/injection easier, the `dns-proto.h` file includes C++ helper classes for building DNS packets. - Other library entrypoints that don't require network activity (e.g. `ares_parse_*_reply`) are tested directly. - A couple of the tests use a helper method of the test fixture to inject memory allocation failures, using a recent change to the c-ares library that allows override of `malloc`/`free`. - There are some tests of the internal entrypoints of the library (`ares-test-internal.c`), but these are only enabled if the library was configured with `--disable-symbol-hiding` and/or `--enable-expose-statics`. - There is also an entrypoint to allow Clang's [libfuzzer](http://llvm.org/docs/LibFuzzer.html) to drive the packet parsing code in `ares_parse_*_reply`, together with a standalone wrapper for it (`./aresfuzz`) to allow use of command line fuzzers (such as [afl-fuzz](http://lcamtuf.coredump.cx/afl/)) for further [fuzz testing](#fuzzing). Code Coverage Information ------------------------- To generate code coverage information: - Configure both the library and the tests with `./configure --enable-code-coverage` before building. This requires the relevant code coverage tools ([gcov](https://gcc.gnu.org/onlinedocs/gcc/Gcov.html), [lcov](http://ltp.sourceforge.net/coverage/lcov.php)) to be installed locally. - Run the tests with `test/arestest`. - Generate code coverage output with `make code-coverage-capture` in the library directory (i.e. not in `test/`). Fuzzing ------- ### libFuzzer To fuzz the packet parsing code with libFuzzer, follow the main [libFuzzer instructions](http://llvm.org/docs/LibFuzzer.html): - Configure the c-ares library and test suite with a recent Clang and a sanitizer, for example: ```console % export CFLAGS="-fsanitize=fuzzer-no-link,address" % export CC=clang % ./configure --disable-shared && make ``` - Link each of the fuzzer entrypoints in with `ares-fuzz.cc`: ``` % clang -I.. -c ares-test-fuzz.c % clang -I.. -c ares-test-fuzz-name.c % clang++ -fsanitize=fuzzer,address ares-test-fuzz.o ../.libs/libcares.a -o ares-libfuzzer % clang++ -fsanitize=fuzzer,address ares-test-fuzz-name.o ../.libs/libcares.a -o ares-libfuzzer-name ``` - Run the fuzzer using the starting corpus with: ```console % ./ares-libfuzzer fuzzinput/ # OR % ./ares-libfuzzer-name fuzznames/ ``` ### AFL To fuzz using AFL, follow the [AFL quick start guide](http://lcamtuf.coredump.cx/afl/QuickStartGuide.txt): - Download and build AFL. - Configure the c-ares library and test tool to use AFL's compiler wrappers: ```console % export CC=$AFLDIR/afl-gcc % ./configure --disable-shared && make % cd test && ./configure && make aresfuzz aresfuzzname ``` - Run the AFL fuzzer against the starting corpus: ```console % mkdir fuzzoutput % $AFLDIR/afl-fuzz -i fuzzinput -o fuzzoutput -- ./aresfuzz # OR % $AFLDIR/afl-fuzz -i fuzznames -o fuzzoutput -- ./aresfuzzname ``` ### AFL Persistent Mode If a recent version of Clang is available, AFL can use its built-in compiler instrumentation; this configuration also allows the use of a (much) faster persistent mode, where multiple fuzz inputs are run for each process invocation. - Download and build a recent AFL, and run `make` in the `llvm_mode` subdirectory to ensure that `afl-clang-fast` gets built. - Configure the c-ares library and test tool to use AFL's clang wrappers that use compiler instrumentation: ```console % export CC=$AFLDIR/afl-clang-fast % ./configure --disable-shared && make % cd test && ./configure && make aresfuzz ``` - Run the AFL fuzzer (in persistent mode) against the starting corpus: ```console % mkdir fuzzoutput % $AFLDIR/afl-fuzz -i fuzzinput -o fuzzoutput -- ./aresfuzz ``` c-ares-1.27.0/test/install-sh0000755000175000017500000003577614537541750011454 #!/bin/sh # install - install a program, script, or datafile scriptversion=2020-11-14.01; # UTC # This originates from X11R5 (mit/util/scripts/install.sh), which was # later released in X11R6 (xc/config/util/install.sh) with the # following copyright and license. # # Copyright (C) 1994 X Consortium # # Permission is hereby granted, free of charge, to any person obtaining a copy # of this software and associated documentation files (the "Software"), to # deal in the Software without restriction, including without limitation the # rights to use, copy, modify, merge, publish, distribute, sublicense, and/or # sell copies of the Software, and to permit persons to whom the Software is # furnished to do so, subject to the following conditions: # # The above copyright notice and this permission notice shall be included in # all copies or substantial portions of the Software. # # THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR # IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, # FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object.
