Updated Anti-Trojan kernel patches incorporating the fdalloc2 Security Fix.

Hi,

Updated signed_exec kernel option patches for OpenBSD 3.1 Release and
OpenBSD 3.0 Release incorporating the fdalloc2 Security Fix are
available from:

http://www.trojanproof.org/sigexec-obsd3.1r-0.2.tgz

http://www.trojanproof.org/sigexec-obsd3.0r-0.4.tgz

For details on the fdalloc2 Security Fix see:

http://www.openbsd.org/errata.html#fdalloc2 and
http://www.openbsd.org/errata30.html#fdalloc2 respectively.

Note that the reason we have issued these updates is that the fdalloc2
Security Fix patches the kern_exec.c file which is also patched by the
signed_exec kernel option patches with a result that if either the
official OpenBSD fdalloc2 Security Fix patch or our signed_exec kernel
option patch is applied first then the other will fail to apply hence we
have incorporated both for those that want to use the signed_exec kernel
option.

Regards,
