mac80211: Requeue work after scan complete for all VIF types.

2016-03-03T23:07:26+00:00

commit 4fa11ec726a32ea6dd768dbb2e2af3453a98ec0a upstream.

During a sw scan ieee80211_iface_work ignores work items for all vifs.
However after the scan complete work is requeued only for STA, ADHOC
and MESH iftypes.

This occasionally results in event processing getting delayed/not
processed for iftype AP when it coexists with a STA. This can result
in data halt and eventually disconnection on the AP interface.

mac80211: make ieee80211_new_mesh_header return unsigned

2015-10-05T15:54:16+00:00

The function returns always non-negative values.

The problem has been detected using proposed semantic patch
scripts/coccinelle/tests/assign_signed_to_unsigned.cocci [1].

mac80211: implement VHT support for mesh

2015-09-22T13:21:25+00:00

Implement the basics required for supporting very high throughput
with mesh: include VHT information elements in beacons, probe
responses, and peering action frames, and check for compatible VHT
configurations when peering.

mac80211: implement cfg80211_ops to query mesh proxy path table

2014-10-09T09:19:07+00:00

Implement get_mpp and dump_mpp cfg80211_ops to export the content of the
802.11s mesh proxy path table to userspace.

mac80211: use put_unaligned_le in mesh when necessary

2013-11-25T19:51:55+00:00

Use put_unaligned_le16 and put_unaligned_le32 for
mesh_path_error_tx and mesh_path_sel_frame_tx.

mac80211: update mesh beacon on workqueue

2013-06-18T13:57:27+00:00

Instead of updating the mesh beacon immediately when
requested (which would require the sdata_lock()), defer it
to the mac80211 workqueue.

Fixes yet another deadlock on calling sta_info_flush()
with the sdata_lock() held from ieee80211_stop_mesh(). We
could just drop the sdata_lock() around the
mesh_sta_cleanup() call, but this path is also taken from
several non-locked error paths.

mac80211: expire mesh peers based on mesh configuration

2013-06-11T12:16:29+00:00

The time it takes to see the peer link expire may differ
by a minute since sta_expire() is run once a minute as a
mesh housekeeping task.

mac80211: set mesh formation field properly

2013-06-03T15:03:18+00:00

Cap max peerings at 63 in accordance with IEEE-2012 8.4.2.100.7.
Triggers a beacon regeneration every time the number of peerings changes.
Previously this would only happen if the "accepting peerings" bit changed.

mac80211: return new mpath from mesh_path_add()

2013-04-08T07:16:59+00:00

Most times that mesh_path_add() is called, it is followed by
a lookup to get the just-added mpath.  We can instead just
return the new mpath in the case that we allocated one (or the
existing one if already there), so do that.  Also, reorder the
code in mesh_path_add a bit so that we don't need to allocate
in the pre-existing case.
