I reproduced the memory leaks with libapparmor from apparmor 2.8.95~2430-0ubuntu5.1 from trusty-updates, and verified that libapparmor from apparmor 2.8.95~2430-0ubuntu5.2 in trusty-proposed fixes the issue. I did this by running valgrind on aa-notify against each version of the library after having run apparmor regressions tests to generate a lot of events in syslog. Valgrind reported before updating:
definitely lost: 11,586,610 bytes in 1,005,004 blocks after updating, valgrind reported: definitely lost: 40,263 bytes in 824 blocks with the remaining leaked memory looking to be in perl itself. Marking verification-done. ** Tags added: verification-done -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apparmor in Ubuntu. https://bugs.launchpad.net/bugs/1340927 Title: libapparmor aalogparse memory leak Status in AppArmor Linux application security framework: Fix Released Status in AppArmor 2.8 series: Fix Released Status in apparmor package in Ubuntu: Fix Released Bug description: My kern.log is filled by lots of messages so aa-notify tries to parse them on first run. My OS is going down when there's no memory left because aa-notify leaks. I've found that leak is in /usr/bin/aa-notify file in function parse_message. If I comment lines from my ($test) = LibAppArmorc::parse_record($msg); to LibAppArmorc::free_record($test); then all goes fine. Program parses file and no memory leak is happened. Do I've got sources of my version (libapparmor-perl (2.8.0-5.1) from ubuntu) and found that some variables from aa_log_record struct were not freed by the free_record function. These are char *net_local_addr; char *net_foreign_addr; Could this be a reason of a leak? I haven't much time right now to compile and run tests. So I posted just information I've found and commented lines in bugged function to get my system working.
