Revert "mac80211: Fix accounting of the tailroom-needed counter"

2015-01-05T09:33:46+00:00

This reverts commit ca34e3b5c808385b175650605faa29e71e91991b.

It turns out that the p54 and cw2100 drivers assume that there's
tailroom even when they don't say they really need it. However,
there's currently no way for them to explicitly say they do need
it, so for now revert this.

This fixes https://bugzilla.kernel.org/show_bug.cgi?id=90331.

mac80211: add ieee80211_tx_status_noskb

2014-11-28T14:01:51+00:00

This can be used by drivers that cannot reliably map tx status
information onto specific skbs.

mac80211: add tx_status_noskb to rate_control_ops

2014-11-28T14:01:50+00:00

This op works like .tx_status, except it does not need access to the
skb. This will be used by drivers that cannot match tx status
information to specific packets.

cfg80211: clean up beacon loss CQM event

2014-11-26T19:56:42+00:00

Having it as a sub-event for RSSI thresholds is very ugly,
but luckily no userspace actually uses the events yet.

Move the event to its own function call internally and to
its own event attribute in nl80211.

mac80211: notify drivers on sta rate table changes

2014-11-19T18:15:50+00:00

This allows drivers with a firmware or chip-based rate lookup table to
use the most recent default rate selection without having to get it from
per-packet data or explicit ieee80211_get_tx_rate calls

mac80211: allow drivers to support NL80211_SCAN_FLAG_RANDOM_ADDR

2014-11-19T17:46:09+00:00

Allow drivers to support NL80211_SCAN_FLAG_RANDOM_ADDR with software
based scanning and generate a random MAC address for them for every
scan request with the flag.

mac80211: synchronously reserve TID per station

2014-11-19T17:45:36+00:00

In TDLS (e.g., TDLS off-channel) there is a requirement for
some drivers to supply an unused TID between the AP and the
device to the FW, to allow sending PTI requests and to allow
the FW to aggregate on a specific TID for better throughput.

To ensure that the allocated TID is indeed unused, this patch
introduces an API for blocking the driver from TXing on that
TID.

mac80211: add TDLS channel-switch Rx flow

2014-11-19T17:45:26+00:00

When receiving a TDLS channel switch request or response, parse the frame
and call a new tdls_recv_channel_switch op in the low level driver with
the parsed data.

mac80211: introduce TDLS channel switch ops

2014-11-19T17:45:21+00:00

Implement the cfg80211 TDLS channel switch ops and introduce new mac80211
ones for low-level drivers.
Verify low-level driver support for the new ops when using the relevant
wiphy feature bit. Also verify the peer supports channel switching before
passing the command down.

Add a new STA flag to track the off-channel state with the TDLS peer and
make sure to cancel the channel-switch if the peer STA is unexpectedly
removed.

mac80211: add back support for radiotap vendor namespace data

2014-11-10T09:30:43+00:00

Radiotap vendor namespace data might still be useful, but we
reverted it because it used too much space in the RX status.
Put it back, but address the space problem by using a single
bit only and putting everything else into the skb->data.
