cfg80211: remove enum ieee80211_band

2016-04-12T13:56:15+00:00

This enum is already perfectly aliased to enum nl80211_band, and
the only reason for it is that we get IEEE80211_NUM_BANDS out of
it. There's no really good reason to not declare the number of
bands in nl80211 though, so do that and remove the cfg80211 one.

mac80211: synchronize driver rx queues before removing a station

2016-04-05T08:56:34+00:00

Some devices, like iwlwifi, have RSS queues. This may cause a
situation where a disassociation is handled in control path and
results in station removal while there are prior RX frames
that were still not processed in other queues. When they will
be processed the station will be gone, and the frames will be
dropped.
Add a synchronization interface to avoid that. When driver returns
from the synchronization mac80211 may remove the station.

mac80211: pass block ack session timeout to to driver

2016-01-14T10:13:17+00:00

Currently mac80211 does not inform the driver of the session
block ack timeout when starting a rx aggregation session.
Drivers that manage the reorder buffer need to know this
parameter.
Seeing that there are now too many arguments for the
drv_ampdu_action() function, wrap them inside a structure.

mac80211: allow the driver to send EOSP when needed

2015-12-04T13:43:32+00:00

This can happen when the driver needs to send less frames
than expected and then needs to close the SP.
Mac80211 still needs to set the more_data properly based
on its buffer state (ps_tx_buffer and buffered frames on
other TIDs).
To that end, refactor the code that delivers frames upon
uAPSD trigger frames to be able to get only the more_data
bit without actually delivering those frames in case the
driver is just asking to set a NDP with EOSP and MORE_DATA
bit properly set.

mac80211: allow null chandef in tracing

2015-11-03T09:40:59+00:00

In TDLS channel-switch operations the chandef can sometimes be NULL.
Avoid an oops in the trace code for these cases and just print a
chandef full of zeros.

mac80211: remove PM-QoS listener

2015-10-14T16:04:08+00:00

As this API has never really seen any use and most drivers don't
ever use the value derived from it, remove it.

Change the only driver using it (rt2x00) to simply use the DTIM
period instead of the "max sleep" time.

mac80211: allow to transmit A-MSDU within A-MPDU

2015-09-22T13:21:23+00:00

Advertise the capability to send A-MSDU within A-MPDU
in the AddBA request sent by mac80211. Let the driver
know about the peer's capabilities.

mac80211: introduce per vif frame registration API

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

Currently the cfg80211's frame registration api receives wdev, however
mac80211 assumes per device filter configuration and ignores wdev.
Per device filtering is too wasteful, especially for multi-channel
devices.
Introduce new per vif frame registration API and use it for probe
request registrations in ieee80211_mgmt_frame_register()
Also call directly to ieee80211_configure_filter instead of using a work
since it is now allowed to sleep in ieee80211_mgmt_frame_register.

mac80211: extend get_tkip_seq to all keys

2015-05-06T11:29:59+00:00

Extend the function to read the TKIP IV32/IV16 to read the IV/PN for
all ciphers in order to allow drivers with full hardware crypto to
properly support this.

Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next

2015-04-15T16:00:47+00:00

Pull networking updates from David Miller:

 1) Add BQL support to via-rhine, from Tino Reichardt.

 2) Integrate SWITCHDEV layer support into the DSA layer, so DSA drivers
    can support hw switch offloading.  From Floria Fainelli.

 3) Allow 'ip address' commands to initiate multicast group join/leave,
    from Madhu Challa.

 4) Many ipv4 FIB lookup optimizations from Alexander Duyck.

 5) Support EBPF in cls_bpf classifier and act_bpf action, from Daniel
    Borkmann.

 6) Remove the ugly compat support in ARP for ugly layers like ax25,
    rose, etc.  And use this to clean up the neigh layer, then use it to
    implement MPLS support.  All from Eric Biederman.

 7) Support L3 forwarding offloading in switches, from Scott Feldman.

 8) Collapse the LOCAL and MAIN ipv4 FIB tables when possible, to speed
    up route lookups even further.  From Alexander Duyck.

 9) Many improvements and bug fixes to the rhashtable implementation,
    from Herbert Xu and Thomas Graf.  In particular, in the case where
    an rhashtable user bulk adds a large number of items into an empty
    table, we expand the table much more sanely.

10) Don't make the tcp_metrics hash table per-namespace, from Eric
    Biederman.

11) Extend EBPF to access SKB fields, from Alexei Starovoitov.

12) Split out new connection request sockets so that they can be
    established in the main hash table.  Much less false sharing since
    hash lookups go direct to the request sockets instead of having to
    go first to the listener then to the request socks hashed
    underneath.  From Eric Dumazet.

13) Add async I/O support for crytpo AF_ALG sockets, from Tadeusz Struk.

14) Support stable privacy address generation for RFC7217 in IPV6.  From
    Hannes Frederic Sowa.

15) Hash network namespace into IP frag IDs, also from Hannes Frederic
    Sowa.

16) Convert PTP get/set methods to use 64-bit time, from Richard
    Cochran.
