again. This brings back the behaviour of expr in FreeBSD-4, which had been
reverted due to an assumed incompatbility with POSIX.1 for FreeBSD-5.
This issue has been discussed in the freebsd-standards list, and the
consensus was, that POSIX.1 is in fact not violated by this extension,
since it affects only cases of POSIX undefined behaviour (overflow of
signed long).
Other operating systems did upgrade their versions of expr to support
64bit range, after it had been initially brought to FreeBSD. They have
used it for a decade without problems, meanwhile.
The -e option is retained, but it will only select less strict checking
of numeric parameters (leading white-space, leading "+" are allowed and
skipped, an empty string is considered to represent 0 in numeric context.)
The call of check_utility_compat() as a means of establishing backwards
compatibility with FreeBSD-4 is considered obsolete, but preserved in
this commit. It is expected to be removed in a later revision of this
file.

distinguish between UC and WB memory so that we can map the page to
either a region 6 address (for UC) or a region 7 address (for WB).
This change is only now possible, because previously we would map
regions 6 and 7 with 256MB translations and on top of that had the
kernel mapped in region 7 using a wired translation. The introduction
of the PBVM moved the kernel into its own region and freed up region
7 and allowed us to revert to standard page-sized translations.
This commit inroduces pmap_page_to_va() that respects the attribute.
Rather than checking to see if a descriptor is a kqueue, check to see if
its fileops flags include DFLAG_PASSABLE.
At the moment, these two tests are equivalent, but this will change with
the addition of capabilities that wrap kqueues but are themselves of type
DTYPE_CAPABILITY. We already have the DFLAG_PASSABLE abstraction, so let's
use it.
This change has been tested with [the newly improved] tools/regression/kqueue.

Rather than using err() if either of two failure conditions
fires (which can produce spurious error messages), just use
errx() if the one condition that really matters fires.
In practice, this single test is enough to detect the failure
mode we're looking for (kqueue being inherited across fork).

is correctly returned on a remote connection close.
o In the non-blocking socket test compare SS_NBIO against the so->so_state
field instead of the incorrect sb->sb_state field.
o Simplify the ENOTCONN test by removing cases that can't occur.

Modify the existing unit test (from libkqueue) which already exercises process events via
fork() and kill(). Now, the child process simply checks that the 'kqfd' descriptor is invalid.
Some minor modifications were required to make err() work correctly. It seems that this test
was imported using the output of a configure script, but config.h was not included in key
places, nor was its syntax correct (need '#define HAVE_FOO 1' rather than '#define HAVE_FOO').
Finally, change main() to run the "proc" suite by default, but widened the '#if TODO' in
proc.c to include the non-functioning test event_trigger().

This comment refers to CAP_NT_SMBS, which does not exist; it should refer to SMB_CAP_NT_SMBS.
Fixing this comment makes it easier for people interested in Capsicum to grep around for

ALL BIND USERS ARE ENCOURAGED TO UPGRADE IMMEDIATELY
This update addresses the following vulnerability:
CVE-2011-2464
=============
Severity: High
Exploitable: Remotely
Description:
A defect in the affected BIND 9 versions allows an attacker to remotely
cause the "named" process to exit using a specially crafted packet. This
defect affects both recursive and authoritative servers. The code location
of the defect makes it impossible to protect BIND using ACLs configured
within named.conf or by disabling any features at compile-time or run-time.

This is just a simple approach. For reasons unknown OpenSolaris uses a
more sophisticated one involving IPIing the remaining CPUs in reverse
order after the first batch of 32.
I think the benefit of making the code cleaner and easier to understand
outweighs the humour of leaving this intact (or possibly changing it to
#ifdef not_yet_and_probably_never).
