If an eqn(7) starts on a new input line, be sure to output whitespace
in front of it.  Issue found by tedu@ in glOrtho(3).

There are also cases of excessive whitespace before and after
equations.  This patch neither fixes them nor makes them worse.

Make setting the MAC context bit for 11g protection when transmitting
OFDM frames conditional on the node via IEEE80211_F_USEPROT.

ok kettenis@

Don't set CTS to self.  Linux stopped setting this back in
dc271ee0d04d12d6bfabacbec803289a7072fbd9 as it is known
to cause problems.

ok kettenis@

sc_fixed_ridx is initialised to 0 but tested as it it were initialised
to -1.  The result of this is tx frames were always sent out at fixed
rate 0 instead of ni_txrate.

Match the iwn behaviour and test ic_fixed_rate for -1 instead.
Problem spotted by kettenis@ in an earlier diff.

Add three extra checks that test proper removal of the P flag. Currently 2 fail

Update comment to match code; Caspar Schutijser

Document out-of-band data on a socket as an example of an exceptional

Fixes panic seen by henning@

Cleanup smtpd.conf(5).

 - use literal <> around smtpd tables instead of Aq
 - mark up some directives as Ic (previously Ar or unmarked)
 - use Dq/Sq instead of " in a few appropriate places
 - use Bl -column instead of Bd -literal for tables

Document that iwm(4) now supports 7265 and (hopefully) 3160 devices.

Document when closefrom() was added to OpenBSD.  OK bcook@

Add BUGS section to athn(4) man page to warn about broken hostap with USB.

Remove stray ')' from athn(4) "firmware command timed out" error message.

Note that closefrom is an extension.

athn(4) USB drops received frames larger than MCLBYTES.
Count these dropped frames as input errors.

Fix re-associations with athn(4) USB devices in station mode.

Sending the firmware a NODE_ADD command for our BSS doesn't seem to have the
desired effect in station mode. It made a new association after ifconfig
down/up impossible until the device was re-plugged. Leave the code in place
but limit it to hostap mode, just in case it is needed there (hard to tell
since hostap mode seems to be broken -- no beacons are sent by the device).

Also, when leaving run state, reset the RX filer to allow all beacons again.

ok mpi@

If a non-gz manual is read after a gzipped manual, refrain
from throwing a bogus error "wait: No child processes".
As reported by Baptiste Daroussin <bapt at FreeBSD dot org>,
clearing the state variable curp->child after use was forgotten.

Rework ath(4) USB firmware command handling.

The previous code was racy and could dead-lock the USB task thread when a
firmware command timed out (e.g. because the user pulled out the device).
Handle this condition by marking the device as dying as soon as the interrupt
handler gets an IOERROR and making sleeping firmware command threads check
for a dying device when waking up.

Ensure that no thread will try to send a command before the previous one
has completed. There is only a single xfer data structure for firmware
command transfers and reusing an in-flight xfer will give the USB stack
curly toenails ("xfer not free").

Allow up to ATHN_USB_HOST_CMD_RING_COUNT firmware commands to be enqueued
on the command ring, rather than just one. Use standard usdb_wait_task()
when waiting for command ring completion instead of hand-rolled tsleep()s.

gethostbyname(3) would fail when more than 16 addrs/aliases were returned.

Bump MAXADDRS/ALIASES to the original of 35, and silently ignore extras
instead of failing.

Noticed by markson on freenode.

workaround for interrupt coalescing bug not needed on 7265
ok kettenis@ stsp@ phessler@

Fix scanning with athn(4) USB devices.

The driver artificially limited the number of slots for nodes in its net80211
node cache to 8, the rationale being the device firmware can only handle 8
associated nodes at a time. But that's not a good reason to only cache 8 of
potentially many APs in the area.

Instead of crippling upper layer data structures, impose the limit locally
by raising an error if more than 8 nodes are trying to associate (which can
only happen in hostap mode, and hostap mode seems to be broken anyway).
This matches what Linux ath9k does.

Also, use a USB-specific scan timeout callback to we can do USB refcounting
while scanning.

ok kettenis@ stsp@ phessler@

Fix a minor information leak that was introduced in t1_lib.c r1.71, whereby
an additional 28 bytes of .rodata (or .data) is provided to the network. In
most cases this is a non-issue since the memory content is already public.

Issue found and reported by Felix Groebert of the Google Security Team.

ok bcook@ beck@

In athn(4), set USB pipe pointers to NULL after closing pipes. Not really
required since this code runs during device detach but looks prettier.
Also remove an unneeded call to usbd_abort_pipe() which is implied by
usbd_close_pipe().
ok mpi@

Teach athn(4) about USB reference counting to prevent it from causing major
confusion in the USB stack. Also add some usbd_is_dying checks.
