2007-10-11[IEEE80211]: Fix softmac lockdep reports.Johannes Berg1-4/+4
It seems I was actually able to hit this deadlock, on my quad G5 softmac locks up more often than not. This fixes it by using an own workqueue that can safely be flushed under RTNL. Not sure if the patch is correct with the workqueue naming. And don't think with the patch it doesn't continually lock up. It still does, just doesn't invoke lockdep warnings all the time.

2007-09-21[PATCH] softmac: Fix inability to associate with WEP networksLarry Finger1-2/+0
Commit 4cf92a3c was submitted as a fix for bug #8686 at bugzilla.kernel.org (http://bugzilla.kernel.org/show_bug.cgi?id=8686). Unfortunately, the fix led to a new bug, reported by Yoshifuji Hideaki, that prevented association for WEP encrypted networks that use ifconfig to control the device. This patch effectively reverts the earlier commit and does a proper fix for bug #8686. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2006-12-20[PATCH] ieee80211softmac: Fix errors related to the work_struct changesUlrich Kunitz1-2/+2
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).

2006-12-06[PATCH] softmac: Fixed handling of deassociation from APUlrich Kunitz1-2/+12
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 fixes that.

2006-07-28[PATCH] softmac: ERP handling and driver-level notificationsDaniel Drake1-4/+17
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 <dsd@gentoo.org> Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2006-07-05[PATCH] SoftMAC: Prevent multiple authentication attempts on the same networkJoseph Jezak1-5/+20
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.

2006-06-05[PATCH] softmac: Fix handling of authentication failureDaniel Drake1-3/+19
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.

2006-05-06[PATCH] softmac: suggest per-frame-type TX rateDaniel Drake1-12/+7
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).

2006-05-06[PATCH] softmac: make non-operational after being stoppedDaniel Drake1-2/+15
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!) Signed-off-by: Daniel Drake <dsd@gentoo.org> Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2006-04-24[PATCH] softmac: fix SIOCSIWAPJohannes Berg1-4/+16
There are some bugs in the current implementation of the SIOCSIWAP wext, for example that when you do it twice and it fails, it may still try another access point for some reason. This patch fixes this by introducing a new flag that tells the association code that the bssid that is in use was fixed by the user and shouldn't be deviated from.

2006-04-20[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 <linville@tuxdriver.com>
