mac80211: protect non-HT BSS when HT TDLS traffic exists

2015-09-04T12:25:46+00:00

HT TDLS traffic should be protected in a non-HT BSS to avoid collisions. Therefore, when TDLS peers join/leave, check if protection is (now) needed and set the ht_operation_mode of the virtual interface according to the HT capabilities of the TDLS peer(s). This works because a non-HT BSS connection never sets (or otherwise uses) the ht_operation_mode; it just means that drivers must be aware that this field applies to all HT traffic for this virtual interface, not just the traffic within the BSS. Document that. Signed-off-by: Avri Altman Signed-off-by: Johannes Berg

mac80211: remove ieee80211_aes_cmac_calculate_k1_k2()

2015-08-13T09:31:45+00:00

The iwlwifi driver was the only driver that used this, but as it turns out it never needed it, so we can remove it. Signed-off-by: Johannes Berg

mac80211: add pointer for driver use to key

2015-07-17T13:38:22+00:00

Some drivers may need to store data per key, for example for PN validation. Allow this by adding a pointer to the struct that the driver can assign. Signed-off-by: Johannes Berg

mac80211: define TDLS wider BW support bits

2015-07-17T13:38:11+00:00

Allow a device to specify support for the TDLS wider-bandwidth feature. Indicate this support during TDLS setup in the ext-capab IE and set an appropriate station flag when our TDLS peer supports it. This feature gives TDLS peers the ability to use a wider channel than the base width of the BSS. For instance VHT capable TDLS peers connected on a 20MHz channel can extend the channel to 80MHz, if regulatory considerations allow it. Do not cap the bandwidth of such stations by the current BSS channel width in mac80211. Signed-off-by: Arik Nemtsov Signed-off-by: Emmanuel Grumbach Signed-off-by: Johannes Berg

mac80211: support device/driver PN check for CCMP/GCMP

2015-07-17T13:38:02+00:00

When there are multiple RX queues, the PN checks in mac80211 cannot be used since packets might be processed out of order on different CPUs. Allow the driver to report that the PN has been checked, drivers that will use multi-queue RX will have to set this flag. For now, the flag is only valid when the frame has been decrypted, in theory that restriction doesn't have to be there, but in practice the hardware will have decrypted the frame already.

mac80211: remove zero-length A-MPDU subframe reporting

2015-07-17T13:38:00+00:00

As there's no driver using this capability and reporting zero-length A-MPDU subframes for radiotap monitoring, remove the capability to free up two RX flags. Signed-off-by: Johannes Berg

mac80211: don't store napi struct

2015-07-17T13:37:59+00:00

When introducing multiple RX queues, a single NAPI struct will not be sufficient. Instead of trying to store multiple, simply change the API to have the NAPI struct passed to the RX function. This of course means that drivers using rx_irqsafe() cannot use NAPI, but that seems a reasonable trade-off, particularly since only two of all drivers are currently using it at all. While at it, we can now remove the IEEE80211_RX_REORDER_TIMER flag again since this code path cannot have a napi struct anyway. Signed-off-by: Johannes Berg

mac80211: remove exposing 'mfp' to drivers

2015-07-17T13:37:52+00:00

There's no driver using this, so remove it. Signed-off-by: Johannes Berg

mac80211: convert HW flags to unsigned long bitmap

2015-06-10T14:05:36+00:00

As we're running out of hardware capability flags pretty quickly, convert them to use the regular test_bit() style unsigned long bitmaps. This introduces a number of helper functions/macros to set and to test the bits, along with new debugfs code. The occurrences of an explicit __clear_bit() are intentional, the drivers were never supposed to change their supported bits on the fly. We should investigate changing this to be a per-frame flag.
