MFC: glibc2.1 required syscalls (rt_sigaction, rt_sigprocmask, getcwd and

Kill(pid, 0) normally returns 0 on both FreeBSD and Redhat after having

1998-12-21T19:21:36+00:00

performed all sorts of sanity checks. The FreeBSD linux emulator returns
EINVAL in such a case.
Allowing signal 0 to be passed to kill will result in compatible behaviour.

Fix a couple of out-of-bounds array references in mapping between

1998-10-11T04:54:16+00:00

Linux and FreeBSD signal numbers.  Also, check signal numbers passed
in from application programs for validity.  Without these checks,
it is trivial to panic the system from a Linux program.

Oops, the previous fix confused Linux's sigset_t with a pointer type.

It can be integral or a struct in POSIX, so it is difficult to print,
but it is actually declared as unsigned long.  Assume that it is
unsigned integral.

Fixed print format errors.

Move the "retval" (3rd) parameter from all syscall functions and put

1997-11-06T19:29:57+00:00

it in struct proc instead.

This fixes a boatload of compiler warning, and removes a lot of cruft
from the sources.

I have not removed the /*ARGSUSED*/, they will require some looking at.

libkvm, ps and other userland struct proc frobbing programs will need
recompiled.

Removed unused #includes.

Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not

1997-02-22T09:48:43+00:00

ready for it yet.
