Johannes Berg  says:

"Two more fixes for mac80211 - one of them addresses a long-standing
issue that we only found when using vendor events more frequently;
the other addresses some bad information being reported in userspace
that people were starting to actually look at."

mac80211: use bss_conf->dtim_period instead of conf.ps_dtim_period

2014-09-05T11:41:08+00:00

sta_set_sinfo is obviously takes data for specific station.
This specific station is attached to a specific virtual
interface. Hence we should use the dtim_period from this
virtual interface rather than the system wide dtim_period.

Johannes Berg  says:

"Here are a few fixes for mac80211. One has been discussed for a while
and adds a terminating NUL-byte to the alpha2 sent to userspace, which
shouldn't be necessary but since many places treat it as a string we
couldn't move to just sending two bytes.

In addition to that, we have two VLAN fixes from Felix, a mesh fix, a
fix for the recently introduced RX aggregation offload, a revert for
a broken patch (that luckily didn't really cause any harm) and a small
fix for alignment in debugfs."

mac80211: fix agg_status debugfs file alignment

2014-08-26T09:13:37+00:00

The "RX active" string is too long, so the columns get
shifted. Change it to just "RX" to avoid this.

mac80211: fix start_seq_num in Rx reorder offload

2014-08-26T09:13:32+00:00

sta->last_seq_ctrl is the seq_ctrl field from the last header
seen, need to shift it 4 bits to extract the sequence number.
Otherwise the ieee80211_sn_less() check at the top of
ieee80211_sta_manage_reorder_buf drops frames until the sequence
number catches up.

mac80211: mesh_plink: handle confirm frames with new plid

2014-08-26T09:12:55+00:00

The 802.11 standard says when processing a plink confirm
frame:

"If the peerLinkID in the mesh peering instance has not been
set, the Local Link ID field of the Mesh Peering Confirm
request shall be copied into the peerLinkID in the mesh
peering instance."

We were only doing this when receiving an open peering frame,
but it could happen that the open frame gets lost and so we
should handle this case rather than rejecting the confirm and
failing the whole peering process.

mac80211: fix smps mode check for AP_VLAN

2014-08-26T09:12:44+00:00

In ieee80211_sta_ps_deliver_wakeup, sdata->smps_mode is checked. This is
initialized only for the base AP interface, not the individual VLANs.

mac80211: ignore AP_VLAN in ieee80211_recalc_chanctx_chantype

2014-08-26T09:12:37+00:00

When bringing down the AP, a WARN_ON is hit because the bss config chandef
is empty here.
Since AP_VLAN channel settings do not matter for anything chanctx related
(always inherits the settings from the AP interface), let's just ignore
it here.

Revert "mac80211: disable uAPSD if all ACs are under ACM"

2014-08-26T07:45:35+00:00

This reverts commit 24aa11ab8ae03292d38ec0dbd9bc2ac49fe8a6dd.

That commit was wrong since it uses data that hasn't even been set
up yet, but might be a hold-over from a previous connection.

Additionally, it seems like a driver-specific workaround that
shouldn't have been in mac80211 to start with.

mac80211: fix channel switch for chanctx-based drivers

2014-08-22T21:45:49+00:00

The new_ctx pointer is set only for non-chanctx drivers.  This yielded a
crash for chanctx-based drivers during channel switch finalization:

  BUG: unable to handle kernel NULL pointer dereference at 0000000000000020
  IP: ieee80211_vif_use_reserved_switch+0x71c/0xb00 [mac80211]

Use an adequate chanctx pointer to fix this.
