https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D178396 thomas@gibfest.dk changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |thomas@gibfest.dk --- Comment #3 from thomas@gibfest.dk --- Created attachment 165129 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D165129&action= =3Dedit updated patch against stable/10 r293209 The original attachment in this bug no longer works since it doesn't use the newish jailed() to check if the process is jailed.=20 The attachment I'm adding is a patch against stable/10 base r293209 which f= ixes the jailed detection, and also adds jail hostname to the log entry (when a = jail hostname is available). For this patch to work on HEAD the exit1() call needs to be changed, no oth= er changes needed I think. This patch could be a few lines shorter by only having one log() call, which includes a empty string for nonjailed processes and something like ", jid: = xxx (example.com)" for jailed processes. The current is arguably more readable though. Testing with this patch applied: ------------------------------------------------- [tykling@test /usr/src]$ sudo jail -c path=3D/ command=3D/bin/sh # perl -e 'dump' Abort trap (core dumped) # ^Djail: /bin/sh: failed [tykling@test /usr/src]$ sudo jail -c path=3D/ host.hostname=3Dexample.com command=3D/bin/sh # perl -e 'dump' Abort trap (core dumped) # ^Djail: /bin/sh: failed [tykling@test /usr/src]$ perl -e 'dump' Abort trap [tykling@test /usr/src]$ dmesg | tail -3 pid 847 (perl), uid 0, jid 3: exited on signal 6 (core dumped) pid 853 (perl), uid 0, jid 4 (example.com): exited on signal 6 (core dumped) pid 857 (perl), uid 1001: exited on signal 6 [tykling@test /usr/src]$ ------------------------------------------------- I am not good with C so please feel free to comment on style and other problems.
