cfg80211: amend regulatory NULL dereference fix

Johannes' patch for "cfg80211: fix regulatory NULL dereference"
broke user regulaotry hints and it did not address the fact that
last_request was left populated even if the previous regulatory
hint was stale due to the wiphy disappearing.

Fix user reguluatory hints by only bailing out if for those
regulatory hints where a request_wiphy is expected. The stale last_request
considerations are addressed through the previous fixes on last_request
where we reset the last_request to a static world regdom request upon
reset_regdomains(). In this case though we further enhance the effect
by simply restoring reguluatory settings completely.

Nick Kossifidis [Fri, 25 Nov 2011 18:40:20 +0000 (20:40 +0200)]
ath5k: Switch from read-and-clear to write-to-clear method when handling PISR/SISR registers

Since card has 12 tx queues and we want to keep track of the interrupts
per queue we can't fit all these interrupt bits on a single register.
So we have 5 registers, the primary interrupt status register (PISR) and
the 4 secondary interupt status registers (SISRs).

In order to be able to read them all at once (atomic operation) Atheros
introduced the Read-And-Clear registers to make things easier. So when
reading RAC_PISR register, hw does a read on PISR and all SISRs, returns
the value of PISR, copies all SISR values to their shadow copies (RAC_SISRx)
and clears PISR and SISRs. This saves us from reading PISR/SISRs in a sequence.

So far we 've used this approach and MadWiFi/Windows driver etc also used it
for years.

It turns out this operation is not atomic after all (at least not on all cards)
That means it's possible to loose some interrupts because they came after the
copy step and hw cleared them on the clean step !

That's probably the reason we got missed beacons, got stuck queues etc and
couldn't figure out what was going on.

With this patch we switch from RaC operation to an alternative method (that
makes more sense IMHO anyway, I just chose to be on the safe side so far).
Instead of reading RAC registers, we read the normal PISR/SISR registers and
clear any bits we got by writing them back on the register. This will clear only
the bits we got on our read step and leave any new bits unaffected (at least
that's what docs say). So if any new interrupts come up we won't miss it.

I've tested this with an AR5213 and an AR2425 and it seems O.K.

Many thanks to Adrian Chadd for debuging this and reviewing the patch !

v2: Make sure we don't clear PISR bits that map to SISR generated interrupts

mac80211: fix TX warning

Emmanuel reported that my previous patches to enable
handing all fragments to drivers at once triggered
the warning that the SKB queue wasn't empty. This is
happening when we actually queue up some frames and
don't hand them to the driver (queues are stopped).

The reason for it is that my code that splices the
frame(s) over to the pending queue didn't re-init
the local queue, so skb_queue_empty() was false. Fix
this by using the _init versions of the splicing.

Also, convert the warning to WARN_ON_ONCE.

mac80211: timeout tx agg sessions in way similar to rx agg sessions

  Currently tx aggregation is not being timed out even if timeout is
specified when aggregation is opened. Tx tid stays active until delba
arrives from recipient (i.e. recipient times out tid when it is
inactive).
  The problem with this approach is that delba can get lost in the air
and tx tid will stay perpetually opened on the originator while closed
on recipient thus all data sent via this tid will be lost.
  This patch implements tx tid timeouting in way very similar to rx tid
timeouting.
