lwn.git/net/mac80211, branch docs-5.2a

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

2019-02-24T20:06:19+00:00

Three conflicts, one of which, for marvell10g.c is non-trivial and requires some follow-up from Heiner or someone else. The issue is that Heiner converted the marvell10g driver over to use the generic c45 code as much as possible. However, in 'net' a bug fix appeared which makes sure that a new local mask (MDIO_AN_10GBT_CTRL_ADV_NBT_MASK) with value 0x01e0 is cleared. Signed-off-by: David S. Miller

mac80211: allocate tailroom for forwarded mesh packets

2019-02-22T13:00:40+00:00

Forwarded packets enter the tx path through ieee80211_add_pending_skb, which skips the ieee80211_skb_resize call. Fixes WARN_ON in ccmp_encrypt_skb and resulting packet loss. Cc: stable@vger.kernel.org Signed-off-by: Felix Fietkau Signed-off-by: Johannes Berg

mac80211: Use rhashtable_lookup_get_insert_fast instead of racy code

2019-02-22T12:48:48+00:00

The code in mesh_path_add tries to handle the case where a duplicate entry is added to the rhashtable by doing a lookup after a failed insertion. It also tries to handle races by repeating the insertion should the lookup fail. This is now unnecessary as we have rhashtable API functions that can directly return the mathcing object.

Merge remote-tracking branch 'net-next/master' into mac80211-next

2019-02-22T12:48:13+00:00

Merge net-next to resolve a conflict and to get the mac80211 rhashtable fixes so further patches can be applied on top. Signed-off-by: Johannes Berg

mac80211: update HE IEs to D3.3

2019-02-22T12:46:55+00:00

Update element names and new fields according to D3.3 of the HE spec. Signed-off-by: Liad Kaufman Signed-off-by: Luca Coelho Signed-off-by: Johannes Berg

mac80211: ignore quiet mode in probe

2019-02-22T12:46:25+00:00

Some buggy APs keep the CSA IE in probes after the channel switch was completed and can silence us for no good reason. Apply quiet mode only from beacons. If there is real channel switch going on, we will see the beacon anyway. Signed-off-by: Sara Sharon Signed-off-by: Luca Coelho Signed-off-by: Johannes Berg

mac80211: allow CSA to self with immediate quiet

2019-02-22T12:46:04+00:00

Currently, due to some buggy APs that continue to include CSA IEs after the switch, we ignore CSA to same channel. However, some other APs may do CSA to self in order to have immediate quiet. Allow it. Do it only for beacons. Signed-off-by: Sara Sharon Signed-off-by: Luca Coelho Signed-off-by: Johannes Berg

mac80211: notify driver on subsequent CSA beacons

2019-02-22T12:45:51+00:00

Some drivers may want to track further the CSA beacons, for example to compensate for buggy APs that change the beacon count or quiet mode during CSA flow. Signed-off-by: Sara Sharon Signed-off-by: Luca Coelho Signed-off-by: Johannes Berg

mac80211: fix position of vendor_data read

2019-02-22T12:45:38+00:00

The ieee80211_vendor_radiotap was read from the beginning of the skb->data regardless of the existence of other elements in radiotap that would cause it to move to another position. Fix this by taking into account where it really should be. Signed-off-by: Liad Kaufman Signed-off-by: Luca Coelho Signed-off-by: Johannes Berg

mac80211: abort CSA if beacon does not include CSA IEs

2019-02-22T12:43:53+00:00

In case we receive a beacon without CSA IE while we are in the middle of channel switch - abort the operation. Signed-off-by: Sara Sharon Signed-off-by: Luca Coelho Signed-off-by: Johannes Berg
