Version 3.5 brings:
- Atomic commits of ruleset changes (reduce the chance of ending up in an
inconsistent state).
- A 30% reduction in the size of state table entries.
- Source-tracking (limit number of clients and states per client).
- Sticky-address (the flexibility of round-robin with the benefits of
source-hash).
- Significant improvements to interface handling.
- and many more ...
- Remove pflog and pfsync modules. Things will change in such a fashion
that there will be one module with pf+pflog that can be loaded into
GENERIC without problems (which is what most people want). pfsync is no
longer possible as a module.
- Add multicast address for in-kernel multicast pfsync protocol. Protocol
glue will follow once the import is done.
- Add one more mbuf tag
placates gcc which seems to like to complain about -1 being assigned to
an unsigned value. It is well defined and intended, but since signess bugs
are being hunted just change to 0xffffffff.
o Mask the lower 8 bits, not the lower 4 bits for the ai_capabilities word.
All 8 bits are defined and the 0xf was almost certainly a typo.
o Define APM_UNKNOWN to 0xff for emulation layer.
do not pick up the first local ip address for the source
ip address, return ENETUNREACH instead.

fixes the problem of UDP sockets getting wedged in a connected state (and
bound to their destination) under heavy load.
Temporary bind/connect should probably be deleted in future
as an optimization, as described in "A Faster UDP" [Partridge/Pink 1993].
Notes:
- INP_LOCK() is already held in udp_output(). The connection is in effect
happening at a layer lower than the socket layer, therefore in theory
socket locking should not be needed.
- Inlining the in_pcbdisconnect() operation buys us nothing (in the case
of the current state of the code), as laddr is not part of the
inpcb hash or the udbinfo hash. Therefore there should be no need
to rehash after restoring laddr in the error case (this was a
concern of the original author of the patch).

sockbuf lock for the oskcet buffer.
so_cred Static after socket creation.
using rawcb_mtx. Hold this mutex while modifying or iterating over
the control list; this means that the mutex is held over calls into
socket delivery code, which no longer causes a lock order reversal as
the routing socket code uses a netisr to avoid recursing socket ->
routing -> socket.
Note: Locking of IPsec consumers of rawcb_list is not included in this
commit.
ALTQ enabled versions of IFQ_* macros by default, as requested by serveral

turned off the ALTQ checks for non-ALTQ kernels.

The problem was that I was using the unified base address of the module
instead of finding the start address of the section in question.
1. Remove a race whereby contigmalloc() would deadlock against the
running processes in the system if they kept reinstantiating
the memory on the active and inactive page queues that it was
trying to flush out. The process doing the contigmalloc() would
sit in "swwrt" forever and the swap pager would be going at full
force, but never get anywhere. Instead of doing it until the
queues are empty, launder for as many iterations as there are
pages in the queue.
2. Do all laundering to swap synchronously; previously, the vnode
laundering was synchronous and the swap laundering not.
3. Increase the number of launder-or-allocate passes to three, from
two, while failing without bothering to do all the laundering on
the third pass if allocation was not possible. This effectively
gives exactly two chances to launder enough contiguous memory,
helpful with high memory churn where a lot of memory from one pass
to the next (and during a single laundering loop) becomes dirtied
again.
I can now reliably hot-plug hardware requiring a 256KB contigmalloc()
without having the kldload/cbb ithread sit around failing to make
progress, while running a busy X session. Previously, it took killing
X to get contigmalloc() to get further (that is, quiescing the system),
and even then contigmalloc() returned failure.
