[Test plan] Run following testcase script inside a LXC container: ``` #!/bin/sh sudo rm -rf /var/crash/* /var/log/apport.log sudo -u mail sh -c "ping 127.0.0.1 > /dev/null" & sleep 0.3 killall -11 ping sleep 0.3 cat /var/log/apport.log ``` apport.log for the affected version: ``` ERROR: apport (pid 6452) Thu Jul 21 12:59:45 2022: called for pid 6449, signal 11, core limit 0, dump mode 2 ERROR: apport (pid 6452) Thu Jul 21 12:59:45 2022: not creating core for pid with dump mode of 2 ERROR: apport (pid 6452) Thu Jul 21 12:59:45 2022: Unhandled exception: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/apport/report.py", line 681, in add_proc_info self["ExecutablePath"] = _read_proc_link( File "/usr/lib/python3/dist-packages/apport/report.py", line 92, in _read_proc_link return os.readlink(path, dir_fd=dir_fd) PermissionError: [Errno 13] Permission denied: 'exe' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/share/apport/apport", line 862, in <module> info.add_proc_info(proc_pid_fd=proc_pid_fd) File "/usr/lib/python3/dist-packages/apport/report.py", line 686, in add_proc_info raise ValueError("not accessible") ValueError: not accessible ERROR: apport (pid 6452) Thu Jul 21 12:59:45 2022: pid: 6452, uid: 0, gid: 0, euid: 8, egid: 8 ERROR: apport (pid 6452) Thu Jul 21 12:59:45 2022: environment: environ({'LANG': 'C.UTF-8', 'PATH': '/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin', 'LISTEN_PID': '6452', 'LISTEN_FDS': '1', 'LISTEN_FDNAMES': 'connection', 'INVOCATION_ID': '1352c67b4a21480a9b35db8012dafb42', 'JOURNAL_STREAM': '8:29587491', 'SYSTEMD_EXEC_PID': '6452'}) ``` The apport log should not show a Traceback. [Where problems could occur] The apport binary is called by the kernel when a process crashes. Worst case scenarios include breaking the apport binary and no problem report is generated any more (or apport uses too much resources). Users will see problems reports inside the container which cause additional load or disk usage. The fix is accompanied by a test case (run in autopkgtest). [Other Info] The autopkgtest for armhf are run inside a LXC container and some test cases like test_crash_setuid_drop trigger this bug. Due to the huge amount of broken autopkgtest tests, the diff for the SRUs are bigger than desired. The individual commits in https://git.launchpad.net/~ubuntu-core-dev/ubuntu/+source/apport/ are probably easier to review. * jammy SRU: https://git.launchpad.net/~ubuntu-core-dev/ubuntu/+source/apport/log/?h=1fa042cc27714c407494b3d6dfd0730bb984f3eb * focal SRU: https://git.launchpad.net/~ubuntu-core-dev/ubuntu/+source/apport/log/?h=eaa92037c7dfba621719c6f81fd75f6a09e90881 To manage notifications about this bug go to: https://bugs.launchpad.net/apport/+bug/1982487/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
