1. phttpget (and thus portsnap) now understands the HTTP_PROXY_AUTH
environment variable and basic HTTP proxy authentication.
2. portsnap.8 now contains a privacy notice.
3. portsnap can now ignore parts of the tree (similar to cvsup
"refuse" directives).
4. portsnap reacts sensibly if host(1) does not exist.
Introduce a new lock for the purpose of synchronizing access to the
UMA boot pages.
Disable recursion on the general UMA lock now that startup_alloc() no
longer uses it.
Eliminate the variable uma_boot_free. It serves no purpose.
Note: This change eliminates a lock-order reversal between a system
map mutex and the UMA lock. See
http://sources.zabbadoz.net/freebsd/lor.html#109 for details.
Attempt to complete the userspace integration of POSIX.1e extended ACLs.
This includes adding support for ACLs into cp(1) and mv(1) userspace
utilities.
For mv(1), if _PC_ACL_EXTENDED is in effect for the source AND destination
operands, the destination file's ACLs shall reflect the source.
For cp(1), if _PC_ACL_EXTENDED is in effect for both source and destination
operands, and -p has been specified, the ACLs from the source shall be
preserved on the destination.

This is a workaround for a complicated issue involving VFS cookies and devfs.
The PR and patch have the details. The ultimate fix requires architectural
changes and clarifications to the VFS API, but this will prevent the system
from panicking when someone does "ls /dev" while running in a shell under the
linuxulator.

MFC Log:
Fix long standing race condition associated with how lockf uses open(2)
for mutual exclusion:
A brief description of the problem:
1) Proc A picks up non-blocking lock on file X
2) Proc B attempts to pickup lock, fails then waits
3) Proc C attempts to pickup lock, fails then waits
4) Proc A releases lock
5) Proc B acquires lock, release it to pickup a non-blocking version
6) Proc C acquires lock, release it to pickup a non-blocking version
7) Both process B and C race each other to pickup lock again
This occurs mainly because the processes do not keep the lock after they have
been waiting on it. They drop it, attempt to re-acquire it. (They use the wait
to notify when the lock has become available then race to pick it up). This
results in additional CPU utilization during the race, and can also result
in processes picking locks up out of order.
This change attempts to correct this problem by eliminating the test/acquire
race and having the operating system handle it.
Un-break processing of device major/minor values with fstat -n. We do
this by accessing the cdev_priv element of the cdev structure. Looking
forward we need a better way to handle this, as this structure shouldn't
be frobbed by userspace.
Convert the primary ACL allocator from malloc(9) to using a UMA zone instead.
Also introduce an aclinit function which will be used to create the UMA zone
for use by file systems at system start up.

Introduce 3 new options for pkg_create(1), -x for using basic regular
expressions for pkg-name, -E for extended regexps and -G for exact matching.
These new options are only meaningful when using the -b flag of pkg_create(1),
and that the default for the -b parameter is now to do glob matching, as in
other pkg_foo utilities that support package patterns.

Quick kill links to the nsmb(8) manual page, there is no such
utility that I can find.
| There is no need to explicitly add "status" to $extra_commands in

Teach vmstat's domemstat_zone() to use memstat_kvm_uma() when the kvm
descriptor is non-NULL, restoring vmstat -z support for core dumps and
kmem access. These were broken with the introduction of UMA.
memstat_malloc:1.6 from HEAD to RELENG_6:
Teach libmemstat(3) how to extract malloc(9) statistics using kvm(3),
so that libmemstat can be used to view full memory statistics from
kernel core dumps and /dev/mem. This is provided via a new query
function, memstat_kvm_malloc(), which is also automatically invoked
by memstat_kvm_all(). A kvm handle must be passed in.
This will allow malloc(9)-specific code to be removed from vmstat(8).
memstat_uma.c:1.10 from HEAD to RELENG_6:
Add memstat_kvm_uma(), an implementation of a libmemstat(3) query routine
that knows how to extract UMA(9) allocator statistics from a core dump or
live memory image using kvm(3). The caller is expected to provide the
necessary kvm_t handle, which is then used by libmemstat(3).
With these changes, it is trivially straight forward to re-introduce
vmstat -z support on core dumps, which was lost when UMA was introduced.
In the short term, this requires including vm/ include files that are not
intended for extra-kernel use, requiring in turn some ugliness.
Merge memstat_uma.c:1.11 from HEAD to RELENG_6:
Define LIBMEMSTAT so that vm_page.h won't perform a nested include of
opt_vmpage.h.
Remove definition of _KERNEL, it is no longer required in order to
include uma_int.h, as the sensitive parts of uma_int.h (a number of
inlines depending on kernel-only constants) are now protected by
_KERNEL.
The use of LIBMEMSTAT here will be cleaned up in the future.
- Use if_printf() and device_printf() and remove vr_unit from the softc.
I had to initialize the ifnet a bit earlier in attach so that the
if_printf()'s in vr_reset() didn't explode with a page fault.
- Use M_ZERO with contigmalloc() rather than an explicit bzero.
- Use callout_*() to manage the callout and make it MPSAFE.
- Fix locking in detach(), we only need to lock across vr_stop().
is an instant MFC as it was actually tested on 5.x and 6.x. Note that like
the change to HEAD, this renames the devices, and there is no easy way on
6.x to create compatibility names in the kernel.

Add a "show malloc" command to DDB, which prints out the current stats for
available kernel malloc types. Quite useful for post-mortem debugging of
memory leaks without a dump device configured on a panicked box.
