I have seen this, but Asterisk never crashes on me (1.8.4-rc2). Please provide a backtrace per https://wiki.asterisk.org/wiki/display/AST/Getting+a+Backtrace By: Holger Hornung (netview) 2011-04-01 18:27:45 It happened again (rev. 312509): [2011-04-02 01:21:46] ERROR[2501]: netsock2.c:245 ast_sockaddr_resolve: getaddrinfo("sip1.speednetwork.de", "(null)", ...): Name or service not known [2011-04-02 01:21:46] WARNING[2501]: acl.c:579 resolve_first: Unable to lookup 'sip1.speednetwork.de' [2011-04-02 01:21:46] WARNING[2501]: acl.c:422 ast_append_ha: Invalid IP address: (null) sorry - no backtrace available at this time! By: Holger Hornung (netview) 2011-04-01 20:45:56 acl.c line 421 If I comment out the error-line no crash occurs: if (!ast_sockaddr_parse(&ha->addr, address, PARSE_PORT_FORBID)) { ast_log(LOG_WARNING, "Invalid IP address: %s\n", address); ast_free_ha(ha); /*if (error) { *error = 1; }*/ return ret; } By: Holger Hornung (netview) 2011-04-01 20:59:55 additional Information: if asterisk is up and the error occurs, I saw only the error messages without any segfaults. Asterisk crashes reproducible after a 'sip reload' or 'core restart now' if a peer cannot be resolved. By: Kinsey Moore (kmoore) 2011-08-18 13:52:32.375-0500 I am also unable to reproduce this issue and I can not find a place where error would be set but not a valid address since every instance of this function call in current trunk uses either NULL or a pointer to a stack variable. For this issue to progress, we need a backtrace to work with. By: Paul Belanger (pabelanger) 2011-08-23 10:30:44.108-0500 You should be able to add a unittest for this, checkout test_netsock2 for more information. Once you can reproduce it with a unit test, upload the patch and we can get it fixed. By: Matt Jordan (mjordan) 2012-03-23 14:16:47.332-0500 Thank you for the bug report. However I am unable to reproduce this issue. We are now going to close this report - please feel free to reopen when you have more information at hand. |
