* ath9k: fix ad-hoc mode beacon selectionFelix Fietkau2011-05-19
| | | | | | | | | | | | | In ad-hoc mode, beacon timers are configured differently compared to AP mode, and (depending on the scenario) can vary enough to make the beacon tasklet not detect slot 0 based on the TSF. Since staggered beacons are not (and cannot be) used in ad-hoc mode, it makes more sense to just hardcode slot 0 here, avoiding unnecessary TSF reads and calculations.

* cfg80211: Use consistent BSS matching between scan and smeJouni Malinen2011-05-19
| | | | | | | | | | | | | | | | | cfg80211 scan code adds separate BSS entries if the same BSS shows up on multiple channels. However, sme implementation does not use the frequency when fetching the BSS entry. Fix this by adding channel information to cfg80211_roamed() and include it in cfg80211_get_bss() calls. Please note that drivers using cfg80211_roamed() need to be modified to fully implement this fix. This commit includes only minimal changes to avoid compilation issues; it maintains the old (broken) behavior for most drivers. ath6kl was the only one that I could test, so I updated it to provide the operating frequency in the roamed event.

* rtlwifi: rtl8192c-common: rtl8192ce: Fix for HT40 regressionLarry Finger2011-05-16
| | | | | | | | | | | | The changes that were made to rtl8192ce when rtl8192cu was added broke HT40. The errors included a typo in rtlwifi, a missing routine in rtl8192ce and a missing callback of that routine in rtl8192c-common. This patch fixes the regression reported in Bug #35082.

* mac80211: annotate and fix RCU in mesh codeJohannes Berg2011-05-16
| | | | | | | | | | | | | | | | This adds proper RCU annotations to the mesh path table code, and fixes a number of bugs in the code that I found while checking the sparse warnings I got as a result of the annotations. Some things like the changes in mesh_path_add() or mesh_pathtbl_init() only serve to shut up sparse, but other changes like the changes surrounding the for_each_mesh_entry() macro fix real RCU bugs in the code.

* mac80211: fix and simplify mesh lockingJohannes Berg2011-05-16
| | | | | | | | | | | | | | | | | | | The locking in mesh_{mpath,mpp}_table_grow not only has an rcu_read_unlock() missing, it's also racy (though really only technically since it's invoked from a single function only) since it obtains the new size of the table without any locking, so two invocations of the function could attempt the same resize. Additionally, it uses synchronize_rcu() which is rather expensive and can be avoided trivially here. Modify the functions to only use the table lock and use call_rcu() instead of synchronize_rcu().

* mac80211: add missing rcu_barrierJohannes Berg2011-05-16
| | | | | | | | | | | | | mac80211 uses call_rcu() with functions that are defined in the module, so it must use rcu_barrier() at module exit time. Luckily, this seems to not be a problem in practice as module unload and unregistration takes a long time and probably does multiple synchronize_rcu().

| * iwlagn: support multiple TBs per commandJohannes Berg2011-05-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current "huge" command handling is a bit confusing, and very limited since only one command may be huge at a time. Additionally, we often copy data around quite pointlessly since we could instead map the existing scan buffer for example and use it directly. This patch makes that possible. The first change is that multiple buffers may be given to each command (this change was prepared earlier so callsites don't need to change). Each of those can be mapped attached to a TB in the TFD, and the command header can use a TB (the first one) in the TFD as well. Doing this allows getting rid of huge commands in favour of mapping existing buffers. The beacon transmission is also optimised to not copy the SKB at all but use multiple TBs.

Due to pointer assignment atomicity I don't think this is a real issue, but I'm not sure, especially on Alpha the current code might be problematic.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the ability to advertise interface combinations in nl80211. This allows the driver to indicate what the combinations are that it supports. "Combinations" of just a single interface are implicit, as previously. Note that cfg80211 will enforce that the restrictions are met, but not for all drivers yet (once all drivers are updated, we can remove the flag and enforce for all). When no combinations are actually supported, an empty list will be exported so that userspace can know if the kernel exported this info or not (although it isn't clear to me what tools using the info should do if the kernel didn't export it). Since some interface types are purely virtual/software and don't fit the restrictions, those are exposed in a new list of pure SW types, not subject to restrictions. This mainly exists to handle AP-VLAN and monitor interfaces in mac80211. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
