mac80211: round IEEE80211_TX_STATUS_HEADROOM up to multiple of 4

2018-05-30T05:50:28Z

[ Upstream commit 651b9920d7a694ffb1f885aef2bbb068a25d9d66 ] This ensures that mac80211 allocated management frames are properly aligned, which makes copying them more efficient. For instance, mt76 uses iowrite32_copy to copy beacon frames to beacon template memory on the chip. Misaligned 32-bit accesses cause CPU exceptions on MIPS and should be avoided.

mac80211: Add RX flag to indicate ICV stripped

2018-01-17T08:38:49Z

commit cef0acd4d7d4811d2d19cd0195031bf0dfe41249 upstream. Add a flag that indicates that the WEP ICV was stripped from an RX packet, allowing the device to not transfer that if it's already checked.

mac80211: fix VLAN handling with TXQs

2017-10-05T07:43:58Z

commit 53168215909281a09d3afc6fb51a9d4f81f74d39 upstream. With TXQs, the AP_VLAN interfaces are resolved to their owner AP interface when enqueuing the frame, which makes sense since the frame really goes out on that as far as the driver is concerned. However, this introduces a problem: frames to be encrypted with a VLAN-specific GTK will now be encrypted with the AP GTK, since the information about which virtual interface to use to select the key is taken from the TXQ. Fix this by preserving info->control.vif and using that in the dequeue function. This now requires doing the driver-mapping in the dequeue as well. Since there's no way to filter the frames that are sitting on a TXQ, drop all frames, which may affect other interfaces, when an AP_VLAN is removed.

mac80211: Move reorder-sensitive TX handlers to after TXQ dequeue

2016-09-30T12:46:57Z

The TXQ intermediate queues can cause packet reordering when more than one flow is active to a single station. Since some of the wifi-specific packet handling (notably sequence number and encryption handling) is sensitive to re-ordering, things break if they are applied before the TXQ. This splits up the TX handlers and fast_xmit logic into two parts: An early part and a late part. The former is applied before TXQ enqueue, and the latter after dequeue. The non-TXQ path just applies both parts at once. Because fragments shouldn't be split up or reordered, the fragmentation handler is run after dequeue. Any fragments are then kept in the TXQ and on subsequent dequeues they take precedence over dequeueing from the FQ structure. This approach avoids having to scatter special cases all over the place for when TXQ is enabled, at the cost of making the fast_xmit and TX handler code slightly more complex.

mac80211: add offset_tsf driver op and use it for mesh

This allows the mesh sync (and debugfs) code to make incremental TSF adjustments, avoiding any uncertainty introduced by delay in programming absolute TSF. Signed-off-by: Thomas Pedersen Signed-off-by: Johannes Berg

mac80211: Add API to report NAN function match

mac80211: Implement add_nan_func and rm_nan_func

mac80211: implement nan_change_conf

2016-09-30T11:21:43Z

Implement nan_change_conf callback which allows to change current NAN configuration (master preference and dual band operation). Store the current NAN configuration in sdata, so it can be used both to provide the driver the updated configuration with changes and also it will be used in hw reconfig flows in next patches.
