* mac80211: rename filesJohannes Berg2008-04-0829-34/+34
| | | | | | | | This patch renames all mac80211 files (except ieee80211_i.h) to get rid of the useless ieee80211_ prefix. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: fix key vs. sta locking problemsJohannes Berg2008-04-0811-229/+385
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Up to now, key manipulation is supposed to run under RTNL to avoid concurrent manipulations and also allow the set_key() hardware callback to sleep. This is not feasible because STA structs are rcu-protected and thus a lot of operations there cannot take the RTNL. Also, key references are rcu-protected so we cannot do things atomically. This patch changes key locking completely: * key operations are now atomic * hardware crypto offload is enabled and disabled from a workqueue, due to that key freeing is also delayed * debugfs code is also run from a workqueue * keys reference STAs (and vice versa!) so during STA unlink the STAs key reference is removed but not the keys STA reference, to avoid races key todo work is run before STA destruction. * fewer STA operations now need the RTNL which was required due to key operations This fixes the locking problems lockdep pointed out and also makes things more light-weight because the rtnl isn't required as much. Note that the key todo lock/key mutex are global locks, this is not required, of course, they could be per-hardware instead.

* mac80211: fix sta-info pinningJohannes Berg2008-04-081-32/+32
| | | | | | | | | | When a STA is supposed to be unlinked but is pinned, it still needs to be unlinked from all structures. Only at the end of the unlink process should we check for pin status and invalidate the callers reference if it is pinned. Move the pin status check down.

* mac80211: make debugfs files root-onlyJohannes Berg2008-04-083-6/+6
| | | | | | | | | | | | | | | Unfortunately, debugfs can be made to access invalid memory by open()ing a file and then waiting until the corresponding debugfs file has been removed (and, probably, the underlying object.) That could be exploited by any user if the user is able to open debugfs files and can cause networking devices, STA entries or similar to disappear which is quite easy to do. Hence, all debugfs files should be root-only. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* mac80211: fix possible sta-debugfs work lockupJohannes Berg2008-04-081-6/+23
| | | | | | | | | | | | | | | | | | | | Because we queue the sta-debugfs-adding work on our mac80211 workqueue (which needs to be flushed under RTNL) and that work needs the RTNL, it can currently deadlock, thanks to Reinette Chatre for pointing out the lockdep warning about this. This patch fixes it by moving this work to the common kernel workqueue (using schedule_work) and canceling it as appropriate. It also fixes a related problem: When a STA is pinned by the debugfs adding work and sta_info_flush() runs concurrently it is not guaranteed that all STAs are removed from the driver before the corresponding interface is removed which may lead to bugs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hi John, Can you please take a look at this patch? drivers/net/wireless/wavelan_cs.c has unusually large number of static inline functions - 27. I looked through them and 20 of them do not seem to warrant inlining. Some are really big; others call mdelay(1) or busy-wait for a bit to be set in a hardware register - it's pointless to optimize such functions for speed. This patch removes "inline" from these static function (regardless of number of callsites - gcc nowadays auto-inlines statics with one callsite).

* b43: Add PIO support for PCMCIA devicesMichael Buesch2008-04-0810-103/+1267
| | | | | | | | | | | | | | | | | | | | This adds PIO support back (D'oh!) for PCMCIA devices. This is a complete rewrite of the old PIO code. It does actually work and we get reasonable performance out of it on a modern machine. On a PowerBook G4 I get a few MBit for TX and a few more for RX. So it doesn't work as well as DMA (of course), but it's a _lot_ faster than the old PIO code (only got a few kBit with that). The limiting factor is the host CPU speed. So it will generate 100% CPU usage when the network interface is heavily loaded. A voluntary preemption point in the RX path makes sure Desktop Latency isn't hurt. PIO is needed for 16bit PCMCIA devices, as we really don't want to poke with the braindead DMA mechanisms on PCMCIA sockets. Additionally, not all PCMCIA sockets do actually support DMA in 16bit mode (mine doesn't). Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* Revert "mac80211: use a struct for bss->mesh_config"John W. Linville2008-04-084-41/+18
| | | | | | | | | | | | This reverts commit 6c4711b4697d93424e4b1f76a9929ba844d714a5. That patch breaks mesh config comparison between beacons/probe reponses, so every beacon from a mesh network would be added as a new bss. Since the comparison has to be performed for every received beacon I believe it is best to save the mesh config in a format easy to compare, rather than do a bunch of unaligned accesses to compare field by field.
