git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next Conflicts: drivers/net/wireless/mac80211_hwsim.c
2012-08-20mac80211: clean up ieee80211_subif_start_xmitJohannes Berg
There's no need to carry around a return value that is always NETDEV_TX_OK anyway. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-20mac80211: pass channel to ieee80211_send_probe_reqJohannes Berg
In multi-channel scenarios, the channel that we will transmit a probe request on isn't always the current channel (which will be NULL anyway) but will instead be the channel that the AP is on. Pass the channel to the ieee80211_send_probe_req() function so it can be used in the different scenarios. The scan code continues to pass the current channel, of course. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-20mac80211: convert ops checks to WARN_ONJohannes Berg
There's no need to BUG_ON when a driver registers invalid operations, warn and return an error. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-20mac80211: check operating channel in scanJohannes Berg
The optimisation of scanning only on the current channel should check the operating channel. Also modify it to compare channel pointer rather than the frequency. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-20mac80211: use RX status band instead of current bandJohannes Berg
Even for single-channel devices it is possible that we switch the channel temporarily (e.g. for scanning) but while doing so process a received frame that was still received on the old channel, so checking the current band is racy. Use the band from status instead. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-20mac80211: don't assume channel is set in tracingJohannes Berg
With the move to multi-channel and away from drv_config(), hw.conf.channel will not always be set, only for devices using the current API instead of the new channel context APIs. Check the channel is set before adding its frequency to the trace data. Also break some overly long lines in the code. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-20mac80211: use oper_channel in rate initJohannes Berg
Using hw.conf.channel is wrong as it could be the temporary channel if the station is added from the workqueue while the device is already on another channel. Use oper_channel instead. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-20mac80211: remove freq/chantype from debugfsJohannes Berg
You can now get these values through iw, and they conflict with multi-channel work. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-20mac80211: remove almost unused local variableJohannes Berg
In ieee80211_beacon_get_tim() we can use the txrc.sband instead of a separate local variable. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-20mac80211: mesh: don't use global channel typeJohannes Berg
Using local->_oper_channel_type in the mesh code is completely wrong as this value is the combination of the various interface channel types and can be a different value from the mesh interface in case there are multiple virtual interfaces. Use sdata->vif.bss_conf.channel_type instead as it tracks the per-vif channel type. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-20mac80211: simplify buffers in aes_128_cmac_vectorJohannes Berg
There's no need to use a single scratch buffer and calculate offsets into it, just use two separate buffers for the separate variables. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-20mac80211: add IEEE80211_HW_P2P_DEV_ADDR_FOR_INTFJohannes Berg
Some devices like the current iwlwifi implementation require that the P2P interface address match the P2P Device address (only one P2P interface is supported.) Add the HW flag IEEE80211_HW_P2P_DEV_ADDR_FOR_INTF that allows drivers to request that P2P Interfaces added while a P2P Device is active get the same MAC address by default. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-20mac80211: support P2P Device abstractionJohannes Berg
After cfg80211 got a P2P Device abstraction, add support to mac80211. Whether it really is supported or not will depend on whether or not the driver has support for it, but mac80211 needs to change to be able to support drivers that need a P2P Device. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-20cfg80211: add P2P Device abstractionJohannes Berg
In order to support using a different MAC address for the P2P Device address we must first have a P2P Device abstraction that can be assigned a MAC address. This abstraction will also be useful to support offloading P2P operations to the device, e.g. periodic listen for discoverability. Currently, the driver is responsible for assigning a MAC address to the P2P Device, but this could be changed by allowing a MAC address to be given to the NEW_INTERFACE command. As it has no associated netdev, a P2P Device can only be identified by its wdev identifier but the previous patches allowed using the wdev identifier in various APIs, e.g. remain-on-channel. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-20mac80211: make ieee80211_beacon_connection_loss_work staticJohannes Berg
There's no need to declare the function in the header file since it's only used in a single place, so make it static. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-20mac80211: check size of channel switch IE when parsingJohannes Berg
The channel switch IE has a fixed size, so we can discard it in parsing if it's not the right size and use the right struct pointer. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-20mac80211: fix CSA handling timerJohannes Berg
The time until the channel switch is in TU, not in milliseconds, so use TU_TO_EXP_TIME() to correctly program the timer. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-20mac80211: clean up CSA handling codeJohannes Berg
Clean up the CSA handling code by moving some of it out of the if and using a C99 initializer for the struct passed to the driver method. While at it, also add a comment that we should wait for a beacon after switching the channel. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-20mac80211: remove unneeded 'bssid' variableJohannes Berg
There's no need to copy the BSSID just to print it, remove the unnecessary variable. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-20mac80211: support A-MPDU status reportingJohannes Berg
Support getting A-MPDU status information from the drivers and reporting it to userspace via radiotap in the standard fields. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-20wireless: add radiotap A-MPDU status fieldJohannes Berg
Define the A-MPDU status field in radiotap, also update the radiotap parser for it and the MCS field that was apparently missed last time. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-20mac80211: add supported rates change notification in IBSSAntonio Quartulli
In IBSS it is possible that the supported rates set for a station changes over time (e.g. it gets first initialised as an empty set because of no available information about rates and updated later). In this case the driver has to be notified about the change in order to update its internal table accordingly (if needed). This behaviour is needed by all those drivers that handle rc internally but leave stations management to mac80211 Reported-by: Gui Iribarren <gui@altermundi.net> Signed-off-by: Antonio Quartulli <ordex@autistici.org> [Johannes - add docs, validate IBSS mode only, fix compilation] Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-20mac80211: clean up mpath_move_to_queue()Thomas Pedersen
Use skb_queue_walk_safe instead, and fix a few issues: - didn't free old skbs on moving - didn't react to failed skb alloc - needlessly held a local pointer to the destination frame queue - didn't check destination queue length before adding skb Signed-off-by: Thomas Pedersen <thomas@cozybit.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-20mac80211: use skb_queue_walk() in mesh_path_assign_nexthopThomas Pedersen
Since all we really want is just to iterate over all skbs, do just that and avoid (de)queueing to a clusmy tmpq. Signed-off-by: Thomas Pedersen <thomas@cozybit.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-20mac80211: avoid using synchronize_rcu in ieee80211_set_probe_respEyal Shapira
This could take a while (100ms+) and may delay sending assoc resp in AP mode with WPS or P2P GO (as setting the probe resp takes place there). We've encountered situations where the delay was big enough to cause connection problems with devices like Galaxy Nexus. Switch to using call_rcu with a free handler. [Arik - rework to use plain buffer and instead of skb] Signed-off-by: Eyal Shapira <eyal@wizery.com> Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-13mac80211: fix unnecessary beacon update after peering status changeMarco Porsch
ieee80211_bss_info_change_notify is called everytime a peer link is established or closed, because the accepting_plinks flag in the meshconf IE *might* have changed. With this patch the corresponding functions return the BSS_CHANGED_BEACON flag when a beacon update is necessary. Also it makes mesh_accept_plinks_update the common place to update the accepting_plinks flag. mesh_accept_plinks_update is called upon plink change and also periodically from ieee80211_mesh_housekeeping. Thus, it also picks up changes of local->num_sta. Signed-off-by: Marco Porsch <marco.porsch@etit.tu-chemnitz.de> Acked-by: Thomas Pedersen <thomas@cozybit.com> Signed-off-by: John W.

2012-08-06Bluetooth: Refactor in hci_le_conn_complete_evtAndre Guedes
This patch moves the hci_conn check to begining of hci_le_conn_ complete_evt in order to improve code's readability and better error handling. Signed-off-by: Andre Guedes <andre.guedes@openbossa.org> Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk>
2012-08-06Bluetooth: Lookup hci_conn in hci_le_conn_complete_evtAndre Guedes
This patch does a trivial code refactoring in hci_conn lookup in hci_le_conn_complete_evt. It performs the hci_conn lookup at the begining of the function since it is used by both flows (error and success). Signed-off-by: Andre Guedes <andre.guedes@openbossa.org> Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk>
2012-08-06Bluetooth: Find hci_conn by BT_CONNECT stateAndre Guedes
This patch changes hci_cs_le_create_conn to perform hci_conn lookup by state instead of bdaddr. Since we can have only one LE connection in BT_CONNECT state, we can perform LE hci_conn lookup by state. This way, we don't rely on hci_sent_cmd_data helper to find the hci_conn object.

2012-08-06Bluetooth: Refactor hci_cs_le_create_connAndre Guedes
This patch does some code refactoring in hci_cs_le_create_conn function. The hci_conn object is only needed in case of failure, therefore hdev locking and hci_conn lookup were moved to if-statement scope. Also, the conn->state check was removed since we should always close the connection if it fails.

2012-08-06Bluetooth: Remove unneeded codeAndre Guedes
This patch removes some unneeded code from hci_cs_le_create_conn. If the hci_conn is not found, it means this LE connection attempt was triggered by a thrid-party tool (e.g. hcitool). We should not create this new hci_conn in LE Create Connection command status event since it is already properly handled in LE Connection Complete event.

2012-08-06Bluetooth: Fix hci_le_conn_complete_evtAndre Guedes
We need to check the 'Role' parameter from the LE Connection Complete Event in order to properly set 'out' and 'link_mode' fields from hci_conn structure. Signed-off-by: Andre Guedes <andre.guedes@openbossa.org> Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk>

2012-08-06Bluetooth: /proc/net/ entries for bluetooth protocolsMasatake YAMATO
lsof command can tell the type of socket processes are using. Internal lsof uses inode numbers on socket fs to resolve the type of sockets. Files under /proc/net/, such as tcp, udp, unix, etc provides such inode information. Unfortunately bluetooth related protocols don't provide such inode information. This patch series introduces /proc/net files for the protocols. This patch against af_bluetooth.c provides facility to the implementation of protocols. This patch extends bt_sock_list and introduces two exported function bt_procfs_init, bt_procfs_cleanup. The type bt_sock_list is already used in some of implementation of protocols. bt_procfs_init prepare seq_operations which converts protocol own bt_sock_list data to protocol own proc entry when the entry is accessed. What I, lsof user, need is just inode number of bluetooth socket. However, people may want more information. The bt_procfs_init takes a function pointer for customizing the show handler of seq_operations. In v4 patch, __acquires and __releases attributes are added to suppress sparse warning. Suggested by Andrei Emeltchenko. In v5 patch, linux/proc_fs.h is included to use PDE. Build error is reported by Fengguang Wu.
