2019-02-26ath10k: fix descriptor size in ce tx completion for WCN3990Rakesh Pillai2-2/+66
When the driver receives the tx completion of the descriptor over ce, it clears the nbytes configured for that particular descriptor. WCN3990 uses ce descriptors with 64-bit address. Currently during handling the tx completion of the descriptors, the nbytes are accessed from the descriptors using ce_desc for 32-bit targets. This will lead to clearing of memory at incorrect offset if DMA MASK is set to greater than 32 bits. Attach different ce tx copy completed handler for targets using address above 32-bit address.

2019-02-26mt76: mt76x02: fix beacon timer issueFelix Fietkau1-3/+3
When mt76x0 and mt76x2 beacon code was unified, it changed the order in which beacon enable and beacon interval are configured. Configuring beacon enable before beacon interval can in some cases cause problems with the beacon timer, leading to clients not waking up properly from powersave mode. Fix this by changing the order back to interval first, then enable.

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.

2019-02-20iwlwifi: remove redundant condition from prior alive dump flowShahar S Matityahu1-16/+0
After the FW image was loaded for the first time, fwrt->smem_cfg.num_lmacs value will no longer be zero since we don't clean it when we stop the device. So if we load the image once and then we fail on a consecutive attempt, the driver will abort any dumping. Solve this by removing the condition. It is safe to remove since when we do the actual dumping in iwl_fw_dbg_collect_sync we check that STATUS_DEVICE_ENABLED bit is still active.

2019-02-20iwlwifi: mvm: implement VHT extended NSS support in rs.cJohannes Berg1-2/+21
For non-offloaded rate control, implement VHT extended NSS support by just ignoring 160 MHz on transmit if the peer doesn't support the full NSS (2). This is pretty unlikely and gets us 160 MHz RX as well as TX in most cases, since the typical case for this workaround is 4x4 AP only doing 2x2 on 160 MHz.

2019-02-20iwlwifi: mvm: Allow retries for probe responsesIlan Peer1-1/+3
When hostapd sends a probe response, it does not request an acknowledgment on the probe response. This setting is propagated to the driver and FW from mac80211, and as a result probe responses are transmitted only once without retries. In congested environments, this reduces the likelihood for finding the AP. To overcome this, enable acknowledgment and retries for probe responses, even in case no acknowledgment is requested. In such a case the retry limit is set to 3. Signed-off-by: Ilan Peer <[email protected]> Signed-off-by: Luca Coelho <[email protected]>

One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; void *entry[]; }; instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.
