CVS commit: src/sys/kern

["Christos Zoulas" <christos%netbsd.org@localhost>]

Module Name:    src
Committed By:   christos
Date:           Mon Nov 13 20:38:32 UTC 2017

Modified Files:
        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.
