| * mac80211: close AP_VLAN interfaces before unregistering allJohannes Berg2013-05-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since Eric's commit efe117ab8 ("Speedup ieee80211_remove_interfaces") there's a bug in mac80211 when it unregisters with AP_VLAN interfaces up. If the AP_VLAN interface was registered after the AP it belongs to (which is the typical case) and then we get into this code path, unregister_netdevice_many() will crash because it isn't prepared to deal with interfaces being closed in the middle of it. Exactly this happens though, because we iterate the list, find the AP master this AP_VLAN belongs to and dev_close() the dependent VLANs. After this, unregister_netdevice_many() won't pick up the fact that the AP_VLAN is already down and will do it again, causing a crash.

| * mac80211: assign AP_VLAN hw queues correctlyJohannes Berg2013-05-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | A lot of code in mac80211 assumes that the hw queues are set up correctly for all interfaces (except for monitor) but this isn't true for AP_VLAN interfaces. Fix this by copying the AP master configuration when an AP VLAN is brought up, after this the AP interface can't change its configuration any more and needs to be brought down to change it, which also forces AP_VLAN interfaces down, so just copying in open() is sufficient.

| * mac80211: fix queue handling crashJohannes Berg2013-05-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code I added in "mac80211: don't start new netdev queues if driver stopped" crashes for monitor and AP VLAN interfaces because while they have a netdev, they don't have queues set up by the driver. To fix the crash, exclude these from queue accounting here and just start their netdev queues unconditionally. For monitor, this is the best we can do, as we can redirect frames there to any other interface and don't know which one that will since it can be different for each frame. For AP VLAN interfaces, we can do better later and actually properly track the queue status. Not doing this is really a separate bug though.

| * mac80211: fix HT beacon-based channel switch handlingJohannes Berg2013-05-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an HT AP is advertising channel switch in a beacon, it doesn't (and shouldn't, according to 802.11-2012 Table 8-20) include a secondary channel offset element. The only possible interpretation is that the previous secondary channel offset remains valid, so use that when switching channel based only on beacon information. VHT requires the Wide Bandwidth Channel Switch subelement to be present in the Channel Switch Wrapper element, so the code for that is probably ok (see 802.11ac Draft 4, 8.4.2.165.)

After switch to passive channel 4965 firmware drops any TX packet until it receives beacon. Before commit 1672c0e3 we waited on channel and retransmit packet after 200ms, that makes we receive beacon on the meantime and association process succeed. New mac80211 behaviour cause that any ASSOC frame fail immediately on iwl4965 and we can not associate. This patch restore old mac80211 behaviour for iwl4965, by removing IEEE80211_HW_REPORTS_TX_ACK_STATUS feature. This feature will be added again to iwl4965 driver, when different, more complex workaround for this firmware issue, will be added to the driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | VHT uses peer AID in the PARTIAL_AID field in TDLS frames. The current design for TDLS is to first add a dummy STA entry before completing TDLS Setup and then update information on this STA entry based on what was received from the peer during the setup exchange. In theory, this could use NL80211_ATTR_STA_AID to set the peer AID just like this is used in AP mode to set the AID of an association station. However, existing cfg80211 validation rules prevent this attribute from being used with set_station operation. To avoid interoperability issues between different kernel and user space version combinations, introduce a new nl80211 attribute for the purpose of setting TDLS peer AID. This attribute can be used in both the new_station and set_station operations. It is not supposed to be allowed to change the AID value during the lifetime of the STA entry, but that validation is left for drivers to do in the change_station callback.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Authentication takes place in userspace, but the beacon is generated in the kernel. Allow userspace to inform the kernel of the authentication method so the appropriate mesh config IE can be set prior to beacon generation when joining the MBSS.

* | | mac80211: fix HT beacon-based channel switch handlingJohannes Berg2013-05-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an HT AP is advertising channel switch in a beacon, it doesn't (and shouldn't, according to 802.11-2012 Table 8-20) include a secondary channel offset element. The only possible interpretation is that the previous secondary channel offset remains valid, so use that when switching channel based only on beacon information. VHT requires the Wide Bandwidth Channel Switch subelement to be present in the Channel Switch Wrapper element, so the code for that is probably ok (see 802.11ac Draft 4, 8.4.2.165.)

He also discovered and fixed some bugs in doing so. When pulling in his patches, I also found a few minor bugs as well and fixed them. This also includes a compile fix for some archs that select the ring buffer but not tracing. I based this off of the last patch you took from me that fixed the merge conflict error, as that was the commit that had all the changes I needed for this set of changes." * tag 'trace-fixes-v3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing/kprobes: Support soft-mode disabling tracing/kprobes: Support ftrace_event_file base multibuffer tracing/kprobes: Pass trace_probe directly from dispatcher tracing/kprobes: Increment probe hit-count even if it is used by perf tracing/kprobes: Use bool for retprobe checker ftrace: Fix function probe when more than one probe is added ftrace: Fix the output of enabled_functions debug file ftrace: Fix locking in register_ftrace_function_probe() tracing: Add helper function trace_create_new_event() to remove duplicate code tracing: Modify soft-mode only if there's no other referrer tracing: Indicate enabled soft-mode in enable file tracing/kprobes: Fix to increment return event probe hit-count ftrace: Cleanup regex_lock and ftrace_lock around hash updating ftrace, kprobes: Fix a deadlock on ftrace_regex_lock ftrace: Have ftrace_regex_write() return either read or error tracing: Return error if register_ftrace_function_probe() fails for event_enable_func() tracing: Don't succeed if event_enable_func did not register anything ring-buffer: Select IRQ_WORK
