src/sys/kern: kern_exec.c
Log Message:
Use the pathbuf which we pass to namei() (which is always absolute) as the
resolved pathname. We need this in the case of scripts where p_path needs
to point to the interpreter and not the script itself. Otherwise things
like perl script that depend on /proc/$$/exe to re-exec themselves end up
being fork bombs.
In reality we should be using the fully resolved/canonicalized path here, but
namei is not giving it back to us.
