2b50c24554 [PATCH] softmac: Fixed handling of deassociation from AP
In 2.6.19 a deauthentication from the AP doesn't start a
reassociation by the softmac code. It appears that
mac->associnfo.associating must be set and the
ieee80211softmac_assoc_work function must be scheduled. This patch

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.

c9308b06c0 [PATCH] ieee80211: Move IV/ICV stripping into ieee80211_rx
This patch adds a host_strip_iv_icv flag to ieee80211 which indicates that
ieee80211_rx should strip the IV/ICV/other security features from the payload.
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.

This patch also adds some sensible variable reuse (idx vs keyidx) in

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.

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

The complication here is that we need to encrypt a management frame during

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.

Yeah, known 'bug', we have that code there but never use it. Feel free
to submit a patch (to John Linville, CC netdev and softmac-dev) to
remove it.

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).

6d92f83ffa [PATCH] softmac: deauthentication implies deassociation
The 802.11 specs state that deauthenticating also implies
disassociating. This patch implements that, which improve the behaviour
of SIOCSIWMLME.
