TIME_WAIT socket recycling code to redo the pcb lookup w/out
resetting the inp pointer. Therefore we used the stale pcb,
which leads us to reply with a RST to SYNs received on TIME_WAIT
sockets. Also move the findpcb label below the pf pcb cache lookup,
to avoid using a stale pcb when the caching code gets activated.

pcb. the state key ptr in the pcb is the one that had to be used by pf
outbound. but by convention the state key pointer in the pkthdr is the one
used INbound, so pf follows its reverse pointer to find the sk to use,
and since a reverse doesn't exist for locally terminated connections the
reverse pointer is null and thus the whole game a noop.
note that this only affects packets FROM local udp/tcp sockets, for the
other direction everything works as expected.

of expected semantics. thus, for return packets coming out of an ipsec
tunnel, we need to clear the pf state key pointer in the mbuf header
to prevent a state for encapsulated traffic to be linked to the
decapsulated traffic one.

skipping bitmasks to cover the entire 65536 port space - previously
they covered 512-1024 only.
sysctl needs to be updated to cope with this change; please
"make includes" before rebuilding it.

when we first do a pcb lookup and we have a pointer to a pf state key
in the mbuf header, store the state key pointer in the pcb and a pointer
to the pcb we just found in the state key. when either the state key
or the pcb is removed, clear the pointers.
on subsequent packets inbound we can skip the pcb lookup and just use the
pointer from the state key.
on subsequent packets outbound we can skip the state key lookup and use
the pointer from the pcb.
about 8% speedup with 100 concurrent tcp sessions, should help much more
with more tcp sessions.

Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.

even the unicast address of the remote carp peer. this especially
helps when the multicast carp advertisements are causing problems in
the network (some crappy switches don't do well with multicast), there
are conflicts with VRRP, or the policy of the network does not allow
multicast (most Internet eXchange points didn't allow carped OpenBGP
routers because of the multicast advertisements).

According to millert@ this would have been promoted from a short to an int
anyway, since K&R C cannot pass variables that are smaller than an int.

also fix the correction amount. This was only really visible on tcpdump,
as a "truncated-ip6 - 48 bytes missing" warning. The inner packet made
it into the stack just fine, minus a few sanity checks.

get hung in nfs_reconnect() because they do not have the proper
privilages to bind to a socket, by adding a struct proc * argument
to sobind() (and the *_usrreq() routines, and finally in{6}_pcbbind)

for pf(4) diverted packets; based on patch by Scot Loach; ok beck@
|
|
The option allows a socket to be bound to addresses which are not
local to the machine. In order to receive packets for these addresses
SO_BINDANY needs to be combined with matching outgoing pf(4) divert
rules, see pf.conf(5).

and the one route with the lowest number wins. This will be used by the
routing daemons to resolve the synchronisations issue in case of conflicts.
The nasty bits of this are in the multipath code. If no priority is specified
the kernel will choose an appropriate priority.

simple on/off, allowing more control over how verbose the logging is.
This also allows you to do a further level of filtering in syslog.conf
if you need to.
Also add logging of state changes, inspired by diff provided by
Brian A. Seklecki in PR 5513. These messages are logged by default.

get a timestamp of when the datagram was accepted (by udp(4), for
example) rather than having to take a timestamp with gettimeofday(2)
when recv(2) returns - possibly several hundreds of microseconds later.
May be of use to those interested in precision network timing schemes
or QoS for media applications. Tested on alpha, amd64, i386 and sparc64.

it by reading the queues head pointer. if that pointer is not null
then it takes splnet and dequeues a packet for handling. this is
bad because the ifqueue head is modified at splnet and the sofnet
handlers read it without holding splnet.
this removes that check of the head pointer and simply checks if
the dequeue gave us a packet or not before proceeding.
