* [PATCH] softmac: reduce scan debug outputLarry Finger2006-12-02
| | | | | | | | | When scanning in debug mode, softmac is very chatty in that it puts 3 lines in the logs for each time it scans. This patch has only one line containing all the information previously reported. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* [PATCH] ieee80211: Provide generic get_stats implementationDaniel Drake2006-12-02
| | | | | | | | | | | | bcm43xx and ipw2100 currently duplicate the same simplistic get_stats handler. Additionally, zd1211rw requires the same handler to fix a bug where all stats are reported as 0. This patch adds a generic implementation to the ieee80211 layer, which drivers are free to override. Signed-off-by: Daniel Drake <dsd@gentoo.org> Signed-off-by: John W.

* [PATCH] ieee80211: Drop and count duplicate data frames to remove 'replay ↵Larry Finger2006-12-02
| | | | | | | | | | | | | | | 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. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W.

* [PATCH] ieee80211: Move IV/ICV stripping into ieee80211_rxDaniel Drake2006-12-02
| | | | | | | | | | | | | | | | 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.

* [PATCH] softmac: remove netif_tx_disable when scanningMichael Buesch2006-11-28
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] 2.6.17 missing a call to ieee80211softmac_capabilities from ↵Larry Finger2006-07-05
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] softmac: Fix handling of authentication failureDaniel Drake2006-06-05
| | | | | | | | | | | | | | | | | | | | 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.

To get around this without causing too many headaches, we decided to just use software encryption for this frame.

* [PATCH] softmac: suggest per-frame-type TX rateDaniel Drake2006-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [PATCH] softmac: don't reassociate if user asked for deauthenticationDaniel Drake2006-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | 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. This change makes softmac only attempt reassociation if the remote network itself deauthenticated us.
