| |
Hi,
Do we currently expect the audit system to work with x32 syscalls?
I was playing with the audit system for the first time today (on v4.0-rc2, due to [1]), and it didn't seem to work for me. (Tweaking ptrace.c like the patch below seemed to help, but I may just have configured something wrong.)
I know there was a bunch of activity around this area in mid-2014, but I'm not sure what the final position was...
Thanks, David
