After commit 1928ecab620907a0953f811316d05f367f3f4dba (mac80211: fix and simplify mesh locking) mesh table allocation is performed with the pathtbl_resize_lock taken.

2011-05-16mac80211: annotate and fix RCU in mesh codeJohannes Berg2-56/+102
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.

2011-05-16mac80211: fix and simplify mesh lockingJohannes Berg2-22/+25
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().

2011-05-16mac80211: add missing rcu_barrierJohannes Berg1-0/+2
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().

2011-05-16mac80211: sparse RCU annotationsJohannes Berg16-74/+118
This adds sparse RCU annotations to most of mac80211, only the mesh code remains to be done. Due the the previous patches, the annotations are pretty simple. The only thing that this actually changes is removing the RCU usage of key->sta in debugfs since this pointer isn't actually an RCU-managed pointer (it only has a single assignment done before the key even goes live). As that is otherwise harmless, I decided to make it part of this patch. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-05-16mac80211: fix TX a-MPDU lockingJohannes Berg3-12/+42
During my quest to make mac80211 not have any RCU warnings from sparse, I came across the a-MPDU code again and it wasn't quite clear why it isn't racy. So instead of assigning the tid_tx array with just the spinlock held in ieee80211_start_tx_ba_session use a separate temporary array protected only by the spinlock and protect all assignments to the "live" array by both the spinlock and the mutex so that other code is easily verified to be correct. 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.

2011-05-16cfg80211: advertise possible interface combinationsJohannes Berg1-4/+12
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>

2011-05-12cfg80211/mac80211: avoid bounce back mac->cfg->mac on sched_scan_stoppedLuciano Coelho4-11/+35
When sched_scan_stopped was called by the driver, mac80211 calls cfg80211, which in turn was calling mac80211 back with a flag "driver_initiated". This flag was used so that mac80211 would do the necessary cleanup but would not call the driver. This was enough to prevent the bounce back between the driver and mac80211, but not between mac80211 and cfg80211. To fix this, we now do the cleanup in mac80211 before calling cfg80211. To help with locking issues, the workqueue was moved from cfg80211 to mac80211.

2011-05-12mac80211: fix another key non-raceJohannes Berg1-2/+4
The code here is only not racy because all the places that assign the pointers it uses are holding the sta_mtx as well as the key_mtx and so can't race against this because this code holds the sta_mtx.

2011-05-12mac80211: make key locking clearerJohannes Berg3-27/+20
The code in ieee80211_del_key() doesn't acquire the key_mtx properly when it dereferences the keys. It turns out that isn't actually necessary since the key_mtx itself seems to be redundant since all key manipulations are done under the RTNL, but as long as we have the key_mtx we should use it the right way too.

2011-05-05mac80211: Postpond ps timer if tx is stopped by othersRajkumar Manoharan1-0/+20
Whenever the driver's queue depth reaches the max, the queues are stopped by the driver till the driver can accept the frames. At the mean time dynamic_ps_timer can be expired due to not receiving packet from upper layer which could restart the transmission at the end of ps work. Due to the mismatch with driver state, mac80211 is unneccesarity buffering all the frames till the driver wakes up the queue. Check whether there is no transmit or the tx queues were stopped by some reasons. If any of the queue was stopped, the postpond ps timer and do not restart netif_tx.

2011-05-05mac80211: set TID of internal mgmt packets to 7Arik Nemtsov1-2/+3
The queue mapping of internal mgmt packets is set to VO. Set the TID value to match the queue mapping. Otherwise drivers that only look at the TID might get confused. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-05-05mac80211: use wake_queue to restart trasmitRajkumar Manoharan1-1/+1
netif_tx_start_all_queues is used to allow the upper layer to transmit frames but it does not restart transmission. To restart the trasmission use netif_tx_wake_all_queues. Not doing so, sometimes stalls the transmission and the application has to be restarted to proceed further. This issue was originally found while sending udp traffic in higer bandwidth in open environment without bgscan.

2011-05-05net: call dev_alloc_name from register_netdeviceJiri Pirko1-4/+0
Force dev_alloc_name() to be called from register_netdevice() by dev_get_valid_name(). That allows to remove multiple explicit dev_alloc_name() calls. The possibility to call dev_alloc_name in advance remains. This also fixes veth creation regresion caused by 84c49d8c3e4abefb0a41a77b25aa37ebe8d6b743 Signed-off-by: Jiri Pirko <jpirko@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
