This does not appear in F15 because F15 doesn't cache information WRT what interfaces are available. The memory leak is fixed in F18 & rawhide. It's a low priority issue as only a single object is leaked (rather than an object per call) and there aren't currently plans to backport the fix to F17. |
Created attachment 616108 [details] example code to recreate the memory leak Description of problem: getaddrinfo() leaks memory Version-Release number of selected component (if applicable): glibc-2.15-56.fc17.x86_64 kernel: 3.5.3-1.fc17.x86_64 gcc-4.7.0-5.fc17.x86_64 How reproducible: always using attached code Steps to Reproduce: 1. cc leak.c -o leak 2. valgrind --leak-check=full --show-reachable=yes ./leak localhost Actual results: ... ==11543== 240 bytes in 1 blocks are still reachable in loss record 1 of 1 ==11543== at 0x4C2884D: malloc (vg_replace_malloc.c:263) ==11543== by 0x4F449FB: make_request (check_pf.c:250) ==11543== by 0x4F44C55: __check_pf (check_pf.c:343) ==11543== by 0x4F0BF08: getaddrinfo (getaddrinfo.c:2305) ==11543== by 0x400716: ip_from_string (in /home/noam/sources/getaddrinfo.bug/leak) ==11543== by 0x400822: main (in /home/noam/sources/getaddrinfo.bug/leak) ... Expected results: Additional info: I also have Fedora15 machine which doesn't show this problem.
