In function iwl_send_cmd_sync(), if the flag CMD_WANT_SKB is set but
we are not provided with a valid SKB (cmd->meta.u.skb == NULL), we need
to remove the CMD_WANT_SKB flag from the TX cmd queue. Otherwise in case
the cmd comes in later, it will possibly set an invalid address. Thus
it causes an invalid memory access.

Previously we allocate Rx SKB with GFP_ATOMIC flag. This is because we need
to hold a spinlock to protect the two rx_used and rx_free lists operation
in the rxq.
spin_lock();
...
element = rxq->rx_used.next;
element->skb = alloc_skb(..., GFP_ATOMIC);
list_del(element);
list_add_tail(&element->list, &rxq->rx_free);
...
spin_unlock();
After spliting the rx_used delete and rx_free insert into two operations,
we don't require the skb allocation in an atomic context any more (the
function itself is scheduled in a workqueue).
spin_lock();
...
element = rxq->rx_used.next;
list_del(element);
...
spin_unlock();
...
element->skb = alloc_skb(..., GFP_KERNEL);
...
spin_lock()
...
list_add_tail(&element->list, &rxq->rx_free);
...
spin_unlock();
This patch should fix the "iwlagn: Can not allocate SKB buffers" warning

AP mode operations are seriously affected if mac80211 runs through a
multi-second scan while the AP is trying to send Beacon frames on the
operation channel. While this could be implemented in a way that does
not cause too many problems, it is not very simple and will require
synchronization with Beacon frame scheduling in the drivers (scan one
channel at a time between Beacon frames). Furthermore, such scanning
takes quite a bit longer time and existing userspace applications
would be likely to timeout while waiting for the results.
For now, just refuse requests for new scans (SIOCSIWSCAN) when in AP
mode. In practice, this moves the rejection from iwl* drivers into
mac80211 to make it apply to every mac80211-based driver.
This issue shows up in associated stations getting disconnected when
something (e.g., Network Manager) requests a scan while the interface
is in AP mode. When doing this continuously (e.g., NM does it every 120
seconds), the network gets close to useless.

Patch does following things
1) This patch fixes the a-band association for passive channels with new
uCode feature that it allows direct scan on passive channels after
auto-switch from passive to active. This enables sending of direct probes
on passive channels, as long as some traffic is detected on that channel.
This improves the scanning for hidden SSIDs in A-band,which is all
passive channels.
This patch fixes the bug no 1748.
http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1748
2) This fix will only work with uCode version 15.28.2.8 and above.
Prior versions of uCode would work only if we heard the traffic within
active dwell time, which is much shorter than passive dwell time and
is shorter than typical beacon periods. This patch also provids full
active dwell time even if we hear traffic late in passive dwell.
3) uCode API version is incremented to 2.

This adds the infrastructure to support older firmware APIs.
The API version number is stored as part of the filename, we first try to
load the most recent firmware and progressively try lower versions.
The API version is also read from the firmware self and stored as part
of the iwl_priv structure. Only firmware that is supported by driver will
be loaded. The version number read from firmware is compared
to supported versions in the driver not the API version used as part of
filename.
An example using this new infrastrucure:

This patch cleans uCode key table bit map iwl_clear_stations_table
since all stations are cleared also the key table must be.
Since the keys are not removed properly on suspend by mac80211
this may result in exhausting key table on resume leading
to memory corruption during removal
This patch also fixes a memory corruption problem reported in
http://marc.info/?l=linux-wireless&m=122641417231586&w=2 and tracked in
http://bugzilla.kernel.org/show_bug.cgi?id=12040.
When the key is removed a second time the offset is set to 255 - this
index is not valid for the ucode_key_table and corrupts the eeprom pointer
(which is 255 bits from ucode_key_table).

So I dug deeper into the DMA problems I had with iwlagn and a kind soul
helped me in that he said something about pci-e alignment and mentioned
the iwl_rx_allocate function to check for crossing 4KB boundaries. Since
there's 8KB A-MPDU support, crossing 4k boundaries didn't seem like
something the device would fail with, but when I looked into the
function for a minute anyway I stumbled over this little gem:
BUG_ON(rxb->dma_addr & (~DMA_BIT_MASK(36) & 0xff));
Clearly, that is a totally bogus check, one would hope the compiler
removes it entirely. (Think about it)
After fixing it, I obviously ran into it, nothing guarantees the
alignment the way you want it, because of the way skbs and their
headroom are allocated. I won't explain that here nor double-check that
I'm right, that goes beyond what most of the CC'ed people care about.
So then I came up with the patch below, and so far my system has
survived minutes with 64K pages, when it would previously fail in
seconds. And I haven't seen a single instance of the TX bug either. But
when you see the patch it'll be pretty obvious to you why.
This should fix the following reported kernel bugs:
http://bugzilla.kernel.org/show_bug.cgi?id=11596http://bugzilla.kernel.org/show_bug.cgi?id=11393http://bugzilla.kernel.org/show_bug.cgi?id=11983
I haven't checked if there are any elsewhere, but I suppose RHBZ will
have a few instances too...
I'd like to ask anyone who is CC'ed (those are people I know ran into
the bug) to try this patch.
I am convinced that this patch is correct in spirit, but I haven't
understood why, for example, there are so many unmap calls. I'm not
entirely convinced that this is the only bug leading to the TX reply
errors.

Before ieee80211_notify_mac() was added, it was presented with the
use case of using it to tell mac80211 that the association may
have been lost because the firmware crashed/reset.
Since then, it has also been used by iwlwifi to (slightly) speed
up re-association after resume, a workaround around the fact that
mac80211 has no suspend/resume handling yet. It is also not used
by any other drivers, so clearly it cannot be necessary for "good
enough" suspend/resume.
Unfortunately, the callback suffers from a severe problem: It only
works for station mode. If suspend/resume happens while in IBSS or
any other mode (but station), then the callback is pointless.
Recently, it has created a number of locking issues, first because
it required rtnl locking rather than RCU due to calling sleeping
functions within the critical section, and now because it's called
by iwlwifi from the mac80211 workqueue that may not use the rtnl
because it is flushed under rtnl.
(cf. http://bugzilla.kernel.org/show_bug.cgi?id=12046)
I think, therefore, that we should take a step back, remove it
entirely for now and add the small feature it provided properly.
For suspend and resume we will need to introduce new hooks, and for
the case where the firmware was reset the driver will probably
simply just pretend it has done a suspend/resume cycle to get
mac80211 to reprogram the hardware completely, not just try to
connect to the current AP again in station mode. When doing so, we
will need to take into account locking issues and possibly defer
to schedule_work from within mac80211 for the resume operation,
while the suspend operation must be done directly.
Proper suspend/resume should also not necessarily try to reconnect
to the current AP, the time spent in suspend may have been short
enough to not be disconnected from the AP, mac80211 will detect
that the AP went out of range quickly if it did, and if the
association is lost then the AP will disassoc as soon as a data
frame is sent. We might also take into account WWOL then, and
have mac80211 program the hardware into such a mode where it is
available and requested.

mac80211 supports multiple virtual interfaces for a single device. For
example, a managed interface (wlan0) and a monitor interface (mon0) can
exist at the same time. Thus priv->iw_mode is not sufficient to track
the wireless mode any more. The patch redefines priv->iw_mode as the
first interface mode (the same as priv->vif->type if priv->vif != NULL).
If another monitor type interface is created later, we don't change
priv->iw_mode into monitor. This way, the original interface still
works. The patch also requests mac80211 to do reassociation after we
change the Rx filter flags.

changes, do not allow aggregation sessions for drivers that
set ampdu_queues.
This is only an interim hack until Intel fixes the requeue issue.

"Clearing" the rate control algorithm is pointless, none of
the algorithms actually uses this operation and it's not even
invoked properly for all channel switching. Also, there's no
need to since rate control algorithms work per station.

This patch:
1. fixes command DMA unmapping, this might be visible only
on platforms where DMA unmapping is no noop such as PPC64 (not tested)
2. attaches correctly high memory part of the host command buffer
3. changes structure of TFD TB
instead of describing transmit buffer (TB) tuple it describes single
TB and makes code more readable on price of one unaligned access
4. eliminates using of IWL_GET/SET_BITs for TFD handling
5. renames TFD structures to mach the HW spec
6. reduces iwl_tx_info size by reserving first TB to the host command
This patch should not have any visible effect on x86 32
This patch is rework of

So after the previous changes we were still unhappy with how
convoluted the API is and decided to make things simpler for
everybody. This completely changes the rate control API, now
taking into account 802.11n with MCS rates and more control,
most drivers don't support that though.

The HT handling has the following deficiencies, which I've
(partially) fixed:
* it always uses the AP info even if there is no AP,
hence has no chance of working as an AP
* it pretends to be HW config, but really is per-BSS
* channel sanity checking is left to the drivers
* it generally lets the driver control too much
HT enabling is still wrong with this patch if you have more than
one virtual STA mode interface, but that never happens currently.
Once WDS, IBSS or AP/VLAN gets HT capabilities, it will also be
wrong, see the comment in ieee80211_enable_ht().
Additionally, this fixes a number of bugs:
* mac80211: ieee80211_set_disassoc doesn't notify the driver any
more since the refactoring
* iwl-agn-rs: always uses the HT capabilities from the wrong stuff
mac80211 gives it rather than the actual peer STA
* ath9k: a number of bugs resulting from the broken HT API
I'm not entirely happy with putting the HT capabilities into
struct ieee80211_sta as restricted to our own HT TX capabilities,
but I see no cleaner solution for now.

This makes mac80211 notify the driver which configuration
actually changed, e.g. channel etc.
No driver changes, this is just plumbing, driver authors are
expected to act on this if they want to.
Also remove the HW CONFIG debug printk, it's incorrect, often
we configure something else.

This patch cleans up a number of things:
* the unusable definition of the HT capabilities/HT information
information elements
* variable names that are hard to understand
* mac80211: move ieee80211_handle_ht to ht.c and remove the unused
enable_ht parameter
* mac80211: fix bug with MCS rate 32 in ieee80211_handle_ht
* mac80211: fix bug with casting the result of ieee80211_bss_get_ie
to an information element _contents_ rather than the
whole element, add size checking (another out-of-bounds
access bug fixed!)
* mac80211: remove some unused return values in favour of BUG_ON
checking
* a few minor other things
