Please try to create a coredump, perhaps by enabling coredumps privileged processes temporarily (see /proc/sys/fs/suid_dumpable). Hi, I can't create coredump (I tried setting 2 to suid_dumpable), can you tell me how to debug this issue? (In reply to piio from comment #2) > I can't create coredump (I tried setting 2 to suid_dumpable), can you tell > me how to debug this issue? Does the issue reproduce if you launch the browser with --no-sandbox? This might help to produce a coredump. It could also help to set kernel.core_pattern=/tmp/core.%p and fs.suid_dumpable=1, and also use ulimit -c unlimited. In general, this is not a secure configuration, but it should allow you to capture a coredump. Hi, I just checked, and with --no-sandbox flash is loading and everything is ok (glibc-2.28.9000-28). I set kernel.core_pattern, fs.suid_dumpable and ulimit but now I don't see crash, only following messages in log: sty 03 14:15:57 (...) audit[11451]: ANOM_ABEND auid=1000 uid=1000 gid=1000 ses=2 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 pid=11451 comm="chrome" exe="/opt/google/chrome/chrome" sig=31 res=1 sty 03 14:15:57 (...) audit[11457]: ANOM_ABEND auid=1000 uid=1000 gid=1000 ses=2 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 pid=11457 comm="chrome" exe="/opt/google/chrome/chrome" sig=31 res=1 In /tmp I don't see eny core.* file Tomas Popela identified the Chromium bug that causes this: https://bugs.chromium.org/p/chromium/issues/detail?id=949312 It's an issue with their sandbox and needs to be fixed there. |
Description of problem: In newer versions (last working correctly is glibc-2.28.9000-22.fc30, maybe glibc-2.28.9000-23 is also ok but I don't tested this version) of glibc, flash player plugin from chrome (ppapi) stopped working with: systemd-coredump[10292]: Process 10285 (chrome) of user 1000 dumped core. Stack trace of thread 1: #0 0x00007fc43ed8a465 __clone (libc.so.6) There is no problem created in abrt Version-Release number of selected component (if applicable): How reproducible: always Steps to Reproduce: 1. install glibc-2.28.9000-24+ 2. 3. Actual results: Stack trace of thread 1: #0 0x00007fc43ed8a465 __clone (libc.so.6) Expected results: flash player plugin working Additional info:
