* iwlwifi: serialize station management actionsReinette Chatre2010-06-14
| | | | | | | | | | | We are seeing some race conditions between incoming station management requests (station add/remove) and the internal unassoc RXON command that modifies station table. Modify these flows to require the mutex to be held and thus serializing them. This fixes http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2207 Signed-off-by: Reinette Chatre <reinette.chatre@intel.com>

| | * iwlwifi: clear driver stations when going downJohannes Berg2010-05-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During a hw restart, mac80211 will attempt to reconfigure all stations. Currently, that fails and leads to warnings because we still have the stations marked active. Therefore, clear all stations when doing down.

| | * iwlwifi: use iwl_find_station lessJohannes Berg2010-05-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since we now store the station ID in each station struct, many places need not look at the station table any more since they can just pull the station ID out of the struct. Remove iwl_get_sta_id() and use iwl_sta_id() instead as appropriate. This reduces the amount of code needed to find the right station significantly, and works since mac80211 passes the station only after it has been fully initialised, ie. even if TX races with station addition it will only be passed to TX once the addition is complete.

| | * iwlwifi: track station IDsJohannes Berg2010-05-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mac80211 allows us to store private data per station, so put the station ID there. This allows us to avoid the station ID lookup when removing regular stations. To also be able to avoid the lookup to remove the special IBSS BSSID station, track its ID in the per-vif private data.

| | * iwlwifi: rework broadcast station managementJohannes Berg2010-05-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the broadcast station is managed along with the interface type, rather than always being present. That leads to a bug with injection -- it is currently not possible to inject frames when the only virtual interface is a monitor, because in that the required broadcast station is missing. Additionally, allocating and deallocating the broadcast station's LQ all the time is wasteful, and the code to support this is fairly complex. So this changes completely the way we manage the broadcast station. Rather than manage it along with any interface, we now allocate it when we bring the device up, and remove it again when we bring the device down. When we bring the device up, we don't immediately program the broadcast station into it, instead we just mark it active and rely on the next restore cycle to upload it to the device. This works because an unassociated RXON is always required at least once to set up device parameters, which implies a reprogramming of stations into the device. As we now manage all stations properly, there no longer is a need for forcing a clearing of them via iwl_clear_ucode_stations(), which can become a lot simpler.

Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* | iwlwifi: Recover TX flow stall due to stuck queueWey-Yi Guy2010-03-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Monitors the internal TX queues periodically. When a queue is stuck for some unknown conditions causing the throughput to drop and the transfer is stop, the driver will force firmware reload and bring the system back to normal operational state. The iwlwifi devices behave differently in this regard so this feature is made part of the ops infrastructure so we can have more control on how to monitor and recover from tx queue stall case per device.

* | iwlwifi: implement new mac80211 station add/remove callsReinette Chatre2010-03-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | mac80211 recently implemented two new callbacks that are used to request station add/remove from the driver. The benefot from these new callbacks are that they enable the driver to sleep while performing this work. This is a big patch since a few things need to be coordinated in this move. First we need to decouple station management from rate scaling, which caused a lot of code to be moved and/or deleted. Next we needed to tie in with mac80211's station management callback and let it direct our station management as well as trigger the rate scaling initialization.

* | iwlwifi: only add broadcast station onceReinette Chatre2010-03-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the broadcast station is added after every RXON command. Change this to only add the broadcast station when interface is added by mac80211. With this we need some extra work to ensure broadcast station is always present since station table is cleared when RXON without ASSOC bit set is sent. To deal with this we re-add all driver known stations to uCode after such an RXON command is sent. We also do some cleanup and remove the various calls to clear the station table. We now only clear the station table in two scenarios: - only clear uCode portion of station table when RXON command without ASSOC bit is sent - clear uCode and driver portion when interface goes down or is removed. We need to do this clearing when interface goes down to deal with the device restart/reconfigure routines which do not remove the interface, but do add the interface during reconfiguration. Previously the keys were also cleared when station table in driver is cleared, this is not done anymore since mac80211 will take care that keys are set and cleared correctly. There is a known issue with this change. Associating with different AP without bringing interface down fails with a firmware error. This is because of the lack of full station notification support and the later patches in this series that complete the station notification support will fix this.

Before this checking even if the BSM loading failed driver tries to initilize the NIC which should not be the case.

* | iwlwifi: change WEP key protection to use mutexJohannes Berg2010-03-09
| | | | | | | | | | | | | | | | | | | | For later station notification support we would like WEP key setting to be done synchronously always. Currently all places from which WEP key is set can sleep, but the usage of sta_lock prevents it to do so. Modify the locking to use priv->mutex instead and thus enable this call to sleep.

* | iwlwifi: remove STATUS_MODE_PENDINGJohannes Berg2010-03-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Since rfkill integration, mac80211 can no longer add an interface while the hardware is not ready, so STATUS_MODE_PENDING can never be set. Also, remove another superfluous channel sanity check and return the commit_rxon return value in case it failed.

* | iwlwifi: remove alive start adhoc restartJohannes Berg2010-03-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This code will never trigger, because when we call this during interface start, neither priv->vif nor priv->iw_mode conditions will be true, and when it happens during reset then priv->vif is also NULL. Also, in both cases the same code will be executed as part of iwl_bss_info_changed(), which contains a copy of this code.
