Module: kamailio Branch: master Commit: 491d1261e04e09f13990d5062c21faca7eb32b37 URL: https://github.com/kamailio/kamailio/commit/491d1261e04e09f13990d5062c21fac… Author: Dennis Yurasov <dennis-y(a)yandex-team.ru> Committer: Daniel-Constantin Mierla <miconda(a)gmail.com> Date: 2021-03-22T15:42:16+01:00 rtpengine: remove square brackets from IPv6 address for getaddrinfo function - After loading from DB rn_address is in form: [x:x:x:x:x:x:x:x]:nnnn, getaddrinfo function expect ipv6 in node argument without square brackets, otherwise, the argument is interpreted as FQDN. --- Modified: src/modules/rtpengine/rtpengine.c --- Diff: https://github.com/kamailio/kamailio/commit/491d1261e04e09f13990d5062c21fac… Patch: https://github.com/kamailio/kamailio/commit/491d1261e04e09f13990d5062c21fac… --- diff --git a/src/modules/rtpengine/rtpengine.c b/src/modules/rtpengine/rtpengine.c index 8b751eb48a..7114b08d40 100644 --- a/src/modules/rtpengine/rtpengine.c +++ b/src/modules/rtpengine/rtpengine.c @@ -1829,6 +1829,7 @@ static int build_rtpp_socks(int lmode, int rtest) { rtpe_reload_lock_get(rtpp_list->rset_lock); for (pnode=rtpp_list->rn_first; pnode!=0; pnode = pnode->rn_next) { char *hostname; + char *hp; if (pnode->rn_umode == 0) { rtpp_socks[pnode->idx] = -1; @@ -1860,11 +1861,23 @@ static int build_rtpp_socks(int lmode, int rtest) { if (cp == NULL || *cp == '\0') cp = CPORT; + if(pnode->rn_umode == 6) { + hp = strrchr(hostname, ']'); + if(hp != NULL) + *hp = '\0'; + + hp = hostname; + if(*hp == '[') + hp++; + } else { + hp = hostname; + } + memset(&hints, 0, sizeof(hints)); hints.ai_flags = 0; hints.ai_family = (pnode->rn_umode == 6) ?
