- thr_kill(2) and thr_exit(2) generally (no argument auditing here.
- A set of syscalls for the process descriptor family, specifically:
pdfork(2), pdgetpid(2) and pdkill(2)
For these syscalls, audit the file descriptor. In the case of pdfork(2)
a pointer to an integer (file descriptor) is passed in as an argument.
We audit the post initialized file descriptor (not the random garbage
that would have been passed in). We will also audit the child process
which was created from the fork operation (similar to what is done for
the fork(2) syscall).
pdkill(2) we audit the signal value and fd, and finally pdgetpid(2)
just the file descriptor:
