Ed Maste 0746301c49 ssh: pass 0 to procctl(2) to operate on self As of `f833ab9dd1` procctl(2) allows idtype P_PID with id = 0 as a shortcut for the calling process ID. The shortcut also bypasses the p_cansee / p_candebug test (since the process is able to act on itself.) At present if the security.bsd.unprivileged_proc_debug sysctl is 0 then procctl(P_PID, getpid(), ... for a process to act on itself will fail, but procctl(P_PID, 0, ... will succeed. This should likely be addressed with a kernel change. In any case the id = 0 shortcut is a tiny optimization for a process to act on itself and allows the self-procctl to succeed, so use it in ssh.

$FreeBSD$

This directory is for the EXACT same use as src/contrib, except it
holds crypto sources.  In other words, this holds raw sources obtained
from various third party vendors, with FreeBSD patches applied.  No
compilation is done from this directory, it is all done from the
src/secure directory.  The separation between src/contrib and src/crypto
is the result of an old USA law, which made these sources export
controlled, so they had to be kept separate.
