[Test plan] Run following testcase script inside a LXC container: ``` rm -f /var/lib/apport/coredump/* ulimit -c 1000000 sleep 86400 & killall -3 sleep ``` Apport will write a core dump into /var/lib/apport/coredump, but this core dump is empty: ``` $ stat /var/lib/apport/coredump/core._usr_bin_sleep.* File: /var/lib/apport/coredump/core._usr_bin_sleep.0.44f483a1-e487-44b3-88d1-805d1026f31d.9059.34839819 Size: 0 Blocks: 0 IO Block: 4096 regular empty file Device: fd00h/64768d Inode: 120848663 Links: 1 Access: (0400/-r--------) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2022-07-22 07:54:48.838682067 +0000 Modify: 2022-07-22 07:54:48.838682067 +0000 Change: 2022-07-22 07:54:48.838682067 +0000 Birth: 2022-07-22 07:54:48.838682067 +0000 ``` This file should not be empty. [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. [Other Info] The autopkgtest for armhf are run inside a LXC container and the test case test_core_dump_packaged_sigquit triggers this bug.
