Since the introduction of ieee80211_sdata_running(), some new code was introduced that uses netif_running() instead. Switch all these instances over. Signed-off-by:

There's a lot of redundant code in mac80211's interface cleanup/down, for example freeing AP beacons is done both when the interface is set DOWN as well as when it is torn down, of which only the former has any effect. Also, a bunch of things should be closer to where they matter, like the MLME timers that we should cancel when disassociating, rather than only when the interface is set DOWN. Clean up all this code.

Some vendor specified mechanisms for 802.1X-style functionality use a different protocol than EAP (even if EAP is vendor-extensible). Support this in mac80211 via the cfg80211 API for it. Signed-off-by:

Some vendor specified mechanisms for 802.1X-style functionality use a different protocol than EAP (even if EAP is vendor-extensible). Allow setting the ethertype for the protocol when a driver has support for this. The default if unspecified is EAP, of course. Note: This is suitable only for station mode, not for AP implementation.

Allow drivers to specify their own set of cipher suites to advertise vendor-specific ciphers. The driver is then required to implement hardware crypto offload for it. Signed-off-by:

Johannes Berg authored
cfg80211 currently rejects all cipher suites it doesn't know about for key length checking purposes. This can lead to inconsistencies when a driver advertises an algorithm that cfg80211 doesn't know about. Remove this rejection so drivers can specify any algorithm they like. Signed-off-by:

With the scan callback now being callable from any context, these unlocks/locks can go away. This makes the code easier to understand, since callers of these functions must no longer be aware that the mutex may be dropped. As Stanislaw is working on iwlwifi scanning, I didn't change it to take advantage of the new mac80211 semantics. Signed-off-by:

Johannes Berg authored
The ieee80211_scan_completed() function was a frequent source of potential deadlocks, since it is called by drivers but may call back into drivers, so drivers had to make sure to call it without any locks held, which frequently lead to more complex code in drivers. Avoid that problem by allowing the function to be called in any context, and queueing the actual work it does. Also update the documentation for it to indicate this. Signed-off-by:

If the symbol offset is 46, it will be counted in both the third and fourth bytes of the mask, and in this case the shift will be negative which can pollute high order bits in the mask. This may negatively impact OFDM symbol detection. Signed-off-by:

When a mac80211-based driver advertises mesh mode support, this will be advertised to userspace. However, if mac80211 was compiled without mesh support, then that won't actually be true. Fix this by removing the bit for mesh if mesh isn't compiled in. Since this synchronizes what we advertise to cfg80211 and actually support, it means we can now rely on cfg80211's interface type checks and need not check again in mac80211. Signed-off-by:

This patch should fix the dodgy signal and noise value reports for most longbow (p54spi) users: e.g.: (an older tcpdump extract) > 2.0 Mb/s 2437 MHz (0x00a0) -49dB signal -41dB noise > 1.0 Mb/s 2437 MHz (0x00a0) 4dB signal -41dB noise The formula is taken from stlc45xx: http://gitorious.org/stlc45xx/mainline/blobs/master/stlc45xx.c#line1199Signed-off-by:

This patch fixes a potential crash (null-pointer de- reference) which was introduced in my previous patch: "mac80211: AMPDU rx reorder timeout timer" During a BA teardown, the pointer to the soon-to-be-gone tid_ampdu_rx element will be nullified. Therefore the release timer mechanism has to be careful not to accidentally access the item without any RCU protection. Signed-off-by:

commit 95a6ccbb46c70cff376684c752831c014c87029d Author: Johannes Berg <johannes.berg@intel.com> Date: Thu Aug 12 15:38:38 2010 +0200 cfg80211/mac80211: extensible frame processing introduced a netlink bug that caused parsing errors in userspace because it forgot to close a nesting, which would advertise a nesting length of zero to userspace, which then completely threw off parsing and led to Illegal nla->nla_type == 0 being printed by libnl.

During initialization each driver reads the default TX power for each individual channel. However mac80211 only accepts the maximum value (which is also handled as default value). As a result, the TX power of the device was being limited to the default value, which is often quite low compared to the real maximum acceptable value. This patch allows each driver to set the maximum value on a per-channel basis which is forwarded to mac80211. The default value will be preserved for now, in case we want to update mac80211 to differentiate between the maximum and default txpower. This fixes bug complaining about limited TX power values like: https://bugzilla.kernel.org/show_bug.cgi?id=16358Signed-off-by:

We missed a check for RF3052 in the config_channel configuration function. As a result the channel is not properly configured for RF3052 devices. This also requires rt2800_config_channel_rf3xxx to support 5GHz channels, so we must apply the TXPOWER_A_TO_DEV and TXPOWER_G_TO_DEV conversions during rt2800_config_channel() Signed-off-by:

The functions rt2800pci_enable_radio and rt2800usb_disable_radio are almost equal and can be merged into rt2800lib. This reduces the number of functions which must be exported from rt2800lib to the drivers at the same time. Also rt2800pci_disable_radio and rt2800usb_disable_radio are almost equal and can be merged into rt2800lib in a similar fashion. Signed-off-by:

The retry count for a frame is calculated by the realized MCS rate subtracting of the requested MCS rate. However during TX done reporting we accidently override the requested MCS rate with the realized MCS rate. This causes the retry count to be reset to 0 always, and feeding invalid rate information into minstrel_ht. Signed-off-by:

Q_INDEX_CRYPTO and ENTRY_OWNER_DEVICE_CRYPTO where initially added with the plan to implement hardware encryption for rt2500pci. However there are no plans to do so anymore as the crypto mechanism in rt2500pci is very different then any other Ralink device. So we can now safely remove the definitions, and don't think about this feature anymore. :) Signed-off-by:

All access to queue->entries through the Q_INDEX/Q_INDEX_DONE variables must be done using spinlock protection. It is best to manage this completely from rt2x00queue.c. For safely looping through all entries in the queue, the function rt2x00queue_for_each_entry is added which will walk from from a index range in a safe manner. This also fixes rt2x00usb which walked the entries list from 0 to length to kill each entry (killing entries must be done from Q_INDEX_DONE to Q_INDEX to enforce TX status reporting to occur in the correct order.

write_tx_desc shouldn't pass a rt2x00dev and skb pointer, instead it should use the same format as other TX frame callback functions, which is passing the data_entry pointer which contains all the information which is needed to work on a TX frame. Most callers of the kick_tx_queue and kill_tx_queue already have the data_queue pointer, so rather then sending the QID with the given function, when the driver requests a new pointer to the data_queue, it is more efficient to just send the data_queue pointer directly.
