Subject: x86/fault: dump command line of faulting process to syslog
Date: Mon, 8 Aug 2022 15:09:16 +0200
If a process segfaults, include the command line of the faulting process
in the syslog.
In the example below, the "crash" program (which simply writes zero to
address 0) was called with the parameters "this is a test":
crash[2326]: segfault at 0 ip 0000561a7969c12e sp 00007ffe97a05630 error = 6 in crash[561a7969c000+1000]
crash[2326] cmdline: ./crash this is a test
Code: 68 ff ff ff c6 05 19 2f 00 00 01 5d c3 0f 1f 80 00 00 00 00 c3 0f 1f ...
