2006-07-27[PATCH] ieee80211: Make ieee80211_rx_any usableDaniel Drake1-10/+28
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.

2006-07-27[PATCH] softmac: ERP handling and driver-level notificationsDaniel Drake4-25/+96
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. Signed-off-by: Daniel Drake <[email protected]> Acked-by: Johannes Berg <[email protected]> Signed-off-by: John W.

2006-07-27[PATCH] ieee80211: small ERP handling additionsDaniel Drake1-0/+1
This adds a flag to the ieee80211_network structure which indicates whether the stored erp_value is valid (a check against 0 is not enough, since an ERP of 0 is valid and very meaningful). I also added the ERP IE bit-definitions to ieee80211.h. This is needed by some upcoming softmac patches.

2006-07-27[PATCH] softmac: do shared key auth in workqueueDaniel Drake1-6/+22
Johann Uhrmann reported a bcm43xx crash and Michael Buesch tracked it down to a problem with the new shared key auth code (recursive calls into the driver) This patch (effectively Michael's patch with a couple of small modifications) solves the problem by sending the authentication challenge response frame from a workqueue entry. I also removed a lone \n from the bcm43xx messages relating to authentication mode - this small change was previously discussed but not patched in.

2006-07-05[PATCH] SoftMAC: Prevent multiple authentication attempts on the same networkJoseph Jezak3-9/+56
This patch addresses the "No queue exists" messages commonly seen during authentication and associating. These appear due to scheduling multiple authentication attempts on the same network. To prevent this, I added a flag to stop multiple authentication attempts by the association layer. I also added a check to the wx handler to see if we're connecting to a different network than the one already in progress. This scenario was causing multiple requests on the same network because the network BSSID was not being updated despite the fact that the ESSID changed.

2006-07-05[PATCH] 2.6.17 missing a call to ieee80211softmac_capabilities from ↵Larry Finger1-0/+3
ieee80211softmac_assoc_req In commit ba9b28d19a3251bb1dfe6a6f8cc89b96fb85f683, 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.

2006-06-05[PATCH] softmac: Fix handling of authentication failureDaniel Drake2-4/+23
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.

2006-06-05[PATCH] softmac: complete shared key authenticationDaniel Drake4-28/+49
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.

2006-05-05[PATCH] softmac: suggest per-frame-type TX rateDaniel Drake4-35/+108
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).

2006-05-05[PATCH] softmac: make non-operational after being stoppedDaniel Drake4-2/+38
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.

2006-05-05[PATCH] softmac: don't reassociate if user asked for deauthenticationDaniel Drake1-2/+3
When wpa_supplicant exits, it uses SIOCSIWMLME to request deauthentication. softmac then tries to reassociate without any user intervention, which isn't the desired behaviour of this signal.

2006-04-19[PATCH] softmac: fix spinlock recursion on reassocMichael Buesch1-1/+2
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). Signed-off-by: John W. Linville <[email protected]>

We don't make much of an attempt to fall back to lower rates, and 54M just isn't reliable enough for many people. In fact, it's not clear we even set it to 11M if we're trying to associate with an 802.11b AP. 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.
