[ Upstream commit cf968937 ] We can't use kfree_skb in irq disable context, because spin_lock_irqsave make sure we are always in irq disable context, use dev_kfree_skb_irq instead of kfree_skb is better than dev_kfree_skb_any.

[ Upstream commit c18d8f50 ] A number of new laptops have been delivered with only a single antenna. In principle, this is OK; however, a problem arises when the on-board EEPROM is programmed to use the other antenna connection. The option of opening the computer and moving the connector is not always possible as it will void the warranty in some cases. In addition, this solution breaks the Windows driver when the box dual boots Linux and Windows. A fix involving a new module parameter has been developed. This commit adds the new parameter and implements the changes needed for the driver. Signed-off-by:

[ Upstream commit fb896c44 ] Until this patch, when TXing non-sta the pending_frames counter wasn't increased, but it WAS decreased in iwl_mvm_rx_tx_cmd_single(), what makes it negative in certain conditions. This in turn caused much trouble when we need to remove the station since we won't be waiting forever until pending_frames gets 0. In certain cases, we were exhausting the station table even in BSS mode, because we had a lot of stale stations. Increase the counter also in iwl_mvm_tx_skb_non_sta() after a successful TX to avoid this outcome. CC: <stable@vger.kernel.org> [3.18+] Signed-off-by:

The debug engine's DMA works in chunks of memory and the size of the buffer really means the start of the last chunk. Since one chunk is 256-byte long, we should configure the device to write to buffer_size - 256. This fixes a situation were the device would write to memory it is not allowed to access.

commit f680f70a upstream. The number of spatial streams that are derived from chain mask for 4x4 devices is using wrong bitmask and conditional check. This is affecting downlink throughput for QCA99x0 devices. Earlier cfg_tx_chainmask is not filled by default until user configured it and so get_nss_from_chainmask never be called. This issue is exposed by recent commit 166de3f1 ("ath10k: remove supported chain mask"). By default maximum supported chain mask is filled in cfg_tx_chainmask.

commit 1f9c6e1b upstream. There were several bugs here. 1) The done label was in the wrong place so we didn't copy any information out when there was no command given. 2) We were using PAGE_SIZE as the size of the buffer instead of "PAGE_SIZE - pos". 3) snprintf() returns the number of characters that would have been printed if there were enough space. If there was not enough space (and we had fixed the memory corruption bug #2) then it would result in an information leak when we do simple_read_from_buffer(). I've changed it to use scnprintf() instead. I also removed the initialization at the start of the function, because I thought it made the code a little more clear.

commit 1a3fe0b2 upstream. During the CT-kill exit flow, the card is powered up and partially initialized to check if the temperature is already low enough. Unfortunately the init bails early because the CT-kill flag is set. Make the code bail early only for HW RF-kill, as was intended by the author. CT-kill is self-imposed and is not really RF-kill.

commit 2cf5eb3a upstream. The code to send the RX PN data (for each TID) to the firmware has a devastating bug: it overwrites the data for TID 0 with all the TID data, leaving the remaining TIDs zeroed. This will allow replays to actually be accepted by the firmware, which could allow waking up the system. Signed-off-by:

commit 54328e64 upstream. In commit 1277fa2a ("rtlwifi: Remove the clear interrupt routine from all drivers"), the code that cleared all interrupt enable bits before setting them was removed for all PCI drivers. This fixed an issue that caused TX to be blocked for 3-5 seconds. On some RTL8821AE units, this change causes soft lockups to occur on boot. For that reason, the portion of the earlier commit that applied to rtl8821ae is reverted. Kernels 4.1 and newer are affected. See http://marc.info/?l=linux-wireless&m=144373370103285&w=2 and https://bugzilla.opensuse.org/show_bug.cgi?id=944978 for two cases where this regression affected user systems. Note that this bug does not appear on any of the developer's setups. For those users whose systems are affected by the TX blockage, but do not lock up on boot, a module parameter is added to disable the interrupt clear Fixes: 1277fa2a ("rtlwifi: Remove the clear interrupt routine from all drivers") Signed-off-by:
