2016-04-25wcn36xx: Use correct command struct for EXIT_BMPS_REQPontus Fuchs

2016-04-25wcn36xx: Pad TIM PVM if neededPontus Fuchs
The wcn36xx FW expects a fixed size TIM PVM in the beacon template. If supplied with a shorter than expected PVM it will overwrite the IE following the TIM. Squashed with fix from Jason Mobarak <jam@cozybit.com>: Patch "wcn36xx: Pad TIM PVM if needed" has caused a regression in mesh beaconing. The field tim_off is always 0 for mesh mode, and thus pvm_len (referring to the TIM length field) and pad are both incorrectly calculated. Thus, msg_body.beacon_length is incorrectly calculated for mesh mode. Fix this.

2016-04-12cfg80211: remove enum ieee80211_bandJohannes Berg
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. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2016-04-05mac80211: allow not sending MIC up from driver for HW cryptoSara Sharon
When HW crypto is used, there's no need for the CCMP/GCMP MIC to be available to mac80211, and the hardware might have removed it already after checking. The MIC is also useless to have when the frame is already decrypted, so allow indicating that it's not present. Since we are running out of bits in mac80211_rx_flags, make the flags field a u64.

2016-01-07wcn36xx: handle rx skb allocation failure to avoid system crashFengwei Yin
Lawrence reported that git clone could make system crash on a Qualcomm ARM soc based device (DragonBoard, 1G memory without swap) running 64bit Debian. It's turned out the crash is related with rx skb allocation failure. git could consume more than 600MB anonymous memory. And system is in extremely memory shortage case. But driver didn't handle the rx allocation failure case. This patch doesn't submit skb to upper layer if rx skb allocation fails. Instead, it reuse the old skb for rx DMA again. It's more like drop the packets if system is in memory shortage case. With this change, git clone is OOMed instead of system crash.

2015-10-28wcn36xx: introduce per-channel ring buffer locksBob Copeland
wcn36xx implements a ring buffer for transmitted frames for each (high and low priority) DMA channel. The ring buffers are lockless: new frames are inserted at the head of the queue, while finished packets are reaped from the tail. Unfortunately, the list manipulations are missing any kind of barriers so are susceptible to various races: for example, a TX completion handler might read an updated desc->ctrl before the head has actually advanced, and then null out the ctl->skb pointer while it is still being used in the TX path. Simplify things here by adding a spin lock when traversing the ring. This change increased stability for me without adding any noticeable overhead on my platform (xperia z).

2015-06-10mac80211: convert HW flags to unsigned long bitmapJohannes Berg
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. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2015-06-02mac80211: remove short slot/short preamble incapable flagsJohannes Berg
There are no drivers setting IEEE80211_HW_2GHZ_SHORT_SLOT_INCAPABLE or IEEE80211_HW_2GHZ_SHORT_PREAMBLE_INCAPABLE, so any code using the two flags is dead; it's also exceedingly unlikely that any new driver could ever need to set these flags. The wcn36xx code is almost certainly broken, but this preserves the previous behaviour. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2015-01-23wcn36xx: initiate TX BA sessionsBob Copeland
Currently, wcn36xx only asks for a TX BA session if it has already established one for RX. Thus, two wcn36xx devices cannot do a-mpdu between themselves since they both wait for the other to go first. Fix this by starting a BA session after a few QoS data frames have been sent to a STA.

2015-01-23wcn36xx: move set_tx_pdu inside set_tx_data/mgmtBob Copeland
The pdu is part of the buffer descriptor, so it makes sense that one function would fill both.

2015-01-23wcn36xx: let device generate qos seq numbersBob Copeland
wcn36xx currently sends an incorrect sequence number into the BA session setup firmware command: it should be saving or updating the ssn in the TX_START ampdu_action callback instead of waiting until TX_OPERATIONAL. However, we can sidestep the issue by letting the hardware generate the sequence numbers for QoS frames, as is done in prima, so do that.

2015-01-23wcn36xx: use !! when assigning int as a booleanBob Copeland
bd->tx_comp is a single bit in a bitfield, so assigning "info->flags & IEEE80211_TX_CTL_REQ_TX_STATUS" only happens to work because TX_STATUS is defined to BIT(0); if it were any other bit this assignment would fail.
