1c865238 2018-10-28 18:11:22 Check existence of IPV6_V6ONLY in evutil_make_listen_socket_ipv6only() (mingw32) MinGW 32-bit 5.3.0 does not defines it and our appveyour [1] build reports this instantly: evutil.c: In function 'evutil_make_listen_socket_ipv6only': evutil.c:392:40: error: 'IPV6_V6ONLY' undeclared (first use in this function) return setsockopt(sock, IPPROTO_IPV6, IPV6_V6ONLY, (void*) &one, [1]: https://www.appveyor.com/docs/windows-images-software/#mingw-msys-cygwin Another solution will be to use mingw64 which has it, but I guess we do want that #ifdef anyway. (cherry picked from commit 23e79fd764b9f36f560d470f0fb60295dd942ac2)
ba148796 2018-06-04 16:43:34 listener: ipv6only socket bind support According to RFC3493 and most Linux distributions, default value is to work in IPv4-mapped mode. If there is a requirement to bind same port on same ip addresses but different handlers for both IPv4 and IPv6, it is required to set IPV6_V6ONLY socket option to be sure that the code works as expected without affected by bindv6only sysctl setting in system. See an example working with this patch: https://gist.github.com/demirten/023008a63cd966e48b0ebcf9af7fc113 Closes: #640 (cherry-pick) (cherry picked from commit 387d91f9ab95df8ac3d7bb58493310ad4a377dcf)
b07e43e6 2018-10-25 00:50:50 Merge branch 'evutil_found_ifaddr-dev' * evutil_found_ifaddr-dev: Cover evutil_v4addr_is_local_()/evutil_v6addr_is_local_() Split evutil_found_ifaddr() into helpers (evutil_v{4,6}addr_is_local()) Use INADDR_ANY over 0 in evutil_found_ifaddr() Replace EVUTIL_V4ADDR_IS_*() macroses with static inline functions Filter link-local IPv4 addresses in evutil_found_ifaddr() (cherry picked from commit b2667b76969c2ea382373f885062b45e82d0ac59)

5a157c87 2016-08-10 16:09:09 evutil: mark ai_find_protocol() static (prototype-less)
40730ae3 2016-05-09 22:34:28 Fix getaddrinfo under solaris (for multiprotocol case) During testing on solaris 11.3, util/getaddrinfo failed at: memset(&hints, 0, sizeof(hints)); hints.ai_flags = EVUTIL_AI_NUMERICHOST; r = evutil_getaddrinfo("1.2.3.4", NULL, &hints, &ai); tt_assert(ai_find_by_protocol(ai, IPPROTO_TCP)); And this is because solaris's getaddrinfo() returns: $6 = { ai_flags = 32, ai_family = 2, ai_socktype = 0, ai_protocol = 0, <-- no proto ai_addrlen = 16, ai_canonname = 0x0, ai_addr = 0x815d658, ai_next = 0x0 <-- nothing else } So we should emulate this too. Plus introduce helper that will search through all results, not only first one. Fixes: util/getaddrinfo Fixes: #354

329acc18 2016-01-31 00:57:16 evutil_parse_sockaddr_port(): fix buffer overflow @asn-the-goblin-slayer: "Length between '[' and ']' is cast to signed 32 bit integer on line 1815. Is the length is more than 2<<31 (INT_MAX), len will hold a negative value. Consequently, it will pass the check at line 1816. Segfault happens at line 1819. Generate a resolv.conf with generate-resolv.conf, then compile and run poc.c. See entry-functions.txt for functions in tor that might be vulnerable. Please credit 'Guido Vranken' for this discovery through the Tor bug bounty program."
