27a884dc3c [SK_BUFF]: Convert skb->tail to sk_buff_data_t
So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes
on 64bit architectures, allowing us to combine the 4 bytes hole left by the
layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4
64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN...
:-)

Many calculations that previously required that skb->{transport,network,
mac}_header be first converted to a pointer now can be done directly, being
meaningful as offsets or pointers.

bb52a653ea [PATCH] ieee80211softmac: Fix setting of initial transmit rates
There is a bug in ieee80211softmac that always sets the user rate
to 11Mbs, no matter the capabilities of the device. This bug was
probably beneficial as long as the bcm43xx cards were rate limited;
however, most are now capable of relatively high speeds. This patch
fixes that bug and eliminates an assert that is no longer needed.

Once the cards are capable of full OFDM speeds, the 24 Mbs rate will
be changed to 54 Mbs.

6bbdce5ac7 [PATCH] softmac: avoid assert in ieee80211softmac_wx_get_rate
Unconfigured bcm43xx device can hit an assert() during wx_get_rate
queries.  This is because bcm43xx calls ieee80211softmac_start late
(i.e. during open instead of probe).

   bcm43xx_net_open ->
      bcm43xx_init_board ->
         bcm43xx_select_wireless_core ->
            ieee80211softmac_start

Fix is to check that device is running before completing
ieee80211softmac_wx_get_rate.

6f07a8a3eb [PATCH] ieee80211softmac: Fix errors related to the work_struct changes
The signature of work functions changed recently from a context
pointer to the work structure pointer. This caused a problem in
the ieee80211softmac code, because the ieee80211softmac_assox_work
function has  been called directly with a parameter explicitly
casted to (void*). This compiled correctly but resulted in a
softlock, because mutex_lock was called with the wrong memory
address. The patch fixes the problem. Another issue was a wrong
call of the schedule_work function. Softmac works again and this
fixes the problem I mentioned earlier in the zd1211rw rx tasklet
patch. The patch is against Linus' tree (commit af1713e0).

837925df02 [PATCH] ieee80211: Drop and count duplicate data frames to remove 'replay detected' log messages
In the SoftMAC version of the IEEE 802.11 stack, not all duplicate messages are
detected. For the most part, there is no difficulty; however for TKIP and CCMP
encryption, the duplicates result in a "replay detected" log message where the
received and previous values of the TSC are identical. This change adds a new
variable to the ieee80211_device structure that holds the 'seq_ctl' value for
the previous frame. When a new frame repeats the value, the frame is dropped and
the appropriate counter is incremented.

This saves on some memmove() calls in the driver and seems like something that
belongs in the stack as it can be used by bcm43xx, ipw2200, and zd1211rw

I will submit the ipw2200 patch separately as it needs testing.

a3df3b6f2e [PATCH] softmac: remove netif_tx_disable when scanning
In the scan section of ieee80211softmac, network transmits are
disabled.  When SoftMAC re-enables transmits, it may override the
wishes of a driver that may have very good reasons for disabling
transmits. At least one failure in bcm43xx can be traced to this
problem. In addition, several unexplained problems may arise from
the unexpected enabling of transmits. Note that making this change
introduces a new bug that would allow transmits for the current session
to be transmitted on the wrong channel; however, the new bug is much
less severe than the one being fixed, as the new one only leads to
a few retransmits, whereas the old one can bring the interface down.

A fix that will not introduce new bugs is being investigated; however,
the current, more serious one should be fixed now.

f2060f039e [PATCH] ieee80211: Make ieee80211_rx_any usable
ieee80211_rx_any is new to 2.6.18-rc1, even though it appears this function
was never completed:

http://lists.sipsolutions.net/pipermail/softmac-dev/2006-February/000103.html

This patch changes ieee80211_rx_any to always claim the skb, which avoids
further driver complexity and the possibility of leaking management frames.
It also exports the function so that people can actually use it.

5acd0c4153 [PATCH] softmac: ERP handling and driver-level notifications
This patch implements ERP handling in softmac so that the drivers can support
protection and preambles properly.

I added a new struct, ieee80211softmac_bss_info, which is used for
BSS-dependent variables like these.

A new hook has been added (bssinfo_change), which allows the drivers to be
notified when anything in bssinfo changes.

I modified the txrates_change API to match the bssinfo_change API. The
existing one is a little messy and the usefulness of providing the old rates
is questionable (and can be implemented at driver level if really necessary).
No drivers are using this API (yet), so this should be safe.

6d41e26510 [PATCH] 2.6.17 missing a call to ieee80211softmac_capabilities from ieee80211softmac_assoc_req
In commit ba9b28d19a, routine
ieee80211softmac_capabilities was added to ieee80211softmac_io.c. As
denoted by its name, it completes the capabilities IE that is
needed in the associate and reassociate requests sent to the
AP. For at least one AP, the Linksys WRT54G V5, the capabilities
field must set the 'short preamble' bit or the AP refuses to
associate. In the commit noted above, there is a call to the
new routine from ieee80211softmac_reassoc_req, but not from
ieee80211softmac_assoc_req. This patch fixes that oversight.

As noted in the subject, v2.6.17 is affected. My bcm43xx card had been
unable to associate since I was forced to buy a new AP. I finally was
able to get a packet dump and traced the problem to the capabilities
info. Although I had heard that a patch was "floating around", I had
not seen it before 2.6.17 was released. As this bug does not affect
security and I seem to have the only AP affected by it, there should
be no problem in leaving it for 2.6.18.

6ae15df16e [PATCH] softmac: Fix handling of authentication failure
My router blew up earlier, but exhibited some interesting behaviour during
its dying moments. It was broadcasting beacons but wouldn't respond to
any authentication requests.

I noticed that softmac wasn't playing nice with this, as I couldn't make it try
to connect to other networks after it had timed out authenticating to my ill
router.

To resolve this, I modified the softmac event/notify API to pass the event
code to the callback, so that callbacks being notified from
IEEE80211SOFTMAC_EVENT_ANY masks can make some judgement. In this case, the
ieee80211softmac_assoc callback needs to make a decision based upon whether
the association passed or failed.

76ea4c7f4c [PATCH] softmac: complete shared key authentication
This patch finishes of the partially-complete shared key authentication
implementation in softmac.

The complication here is that we need to encrypt a management frame during
the authentication process. I don't think there are any other scenarios where
this would have to happen.

To get around this without causing too many headaches, we decided to just use
software encryption for this frame. The softmac config option now selects
IEEE80211_CRYPT_WEP so that we can ensure this available. This also involved
a modification to some otherwise unused ieee80211 API.

8462fe3cd9 [PATCH] softmac: suggest per-frame-type TX rate
This patch is the first step towards rate control inside softmac.

The txrates substructure has been extended to provide
different fields for different types of packets (management/data,
unicast/multicast). These fields are updated on association to values
compatible with the access point we are associating to.

Drivers can then use the new ieee80211softmac_suggest_txrate() function
call when deciding which rate to transmit each frame at. This is
immensely useful for ZD1211, and bcm can use it too.

The user can still specify a rate through iwconfig, which is matched
for all transmissions (assuming the rate they have specified is in
the rate set required by the AP).

At a later date, we can incorporate automatic rate management into
the ieee80211softmac_recalc_txrates() function.

This patch also removes the mcast_fallback field. Sam Leffler pointed
out that this field is meaningless, because no driver will ever be
retransmitting mcast frames (they are not acked).

d57336e3f2 [PATCH] softmac: make non-operational after being stopped
zd1211 with softmac and wpa_supplicant revealed an issue with softmac
and the use of workqueues. Some of the work functions actually
reschedule themselves, so this meant that there could still be
pending work after flush_scheduled_work() had been called during
ieee80211softmac_stop().

This patch introduces a "running" flag which is used to ensure that
rescheduling does not happen in this situation.

I also used this flag to ensure that softmac's hooks into ieee80211 are
non-operational once the stop operation has been started. This simply
makes softmac a little more robust, because I could crash it easily
by receiving frames in the short timeframe after shutting down softmac
and before turning off the ZD1211 radio. (ZD1211 is now fixed as well!)

This fixes a spinlock recursion on receiving a reassoc request.

On reassoc, the softmac calls back into the driver. This results in a
driver lock recursion. This schedules the assoc workqueue, instead
of calling it directly.

Probably, we should defer the _whole_ management frame processing
to a tasklet or workqueue, because it does several callbacks into the driver.
That is dangerous.

This fix should go into linus's tree, before 2.6.17 is released, because it
is remote exploitable (DoS by crash).

This patch makes us default to 11M, which ought to work for most people.
When we actually handle dynamic rate adjustment, we can reconsider the
defaults -- but even then, probably it makes as much sense to start at
11M and adjust it upwards as it does to start at 54M and reduce it.

16f4352733 [PATCH] softmac: reduce scan dwell time
It currently takes something like 8 seconds to do a scan, because we
spend half a second on each channel. Reduce that time to 20ms per
channel.

d94606e058 [PATCH] Minor (janitorial) change to ieee80211
The attached patch removes a potential problem from ieee80211_wx.c, by changing the name of routine
ipw2100_translate_scan to ieee80211_translate_scan. The problem is minor as the routine is declared
static; however, if it were made global, it would pollute the namespace.

4edac92fcf [PATCH] Restore channel setting after scan.
After a scan, we weren't switching back to the original channel if we
were associated with an AP. So NetworkManager's periodic scans would
disrupt connectivity until the ESSID was manually set again. Fix that.
