This patch changes the commands being used to configure encryption and authentication. These new methods are needed for when p2p and hostap support are added. Reviewed-by:

firmware control packets over usb are async acked. This is awaited for by using interruptible wait. This can be interrupted by signal which results in undesirable behavior. Instead wait_event_timeout is used. Reviewed-by:

The driver will send some commands to firmware during the initialization. Currently these commands are sent asynchronously, which means that we firstly insert all of them to a pre-allocated command queue, and then start to process them one by one. The command queue will soon be exhausted if we keep adding new initialization commands. This issue can be resolved by sending initialization commands synchronously because each command is consumed and the buffer is recycled before queuing next command. Signed-off-by:

We need to have the promiscuous mode enabled for older chipsets so that the olderchips hardware does not filters out some valid/necessary frames that need to be sent to mac80211. Fix this by enabling promiscus mode for all the chipsets whose macversion <= AR9160 chipsets. This should fix https://bugzilla.kernel.org/show_bug.cgi?id=45591 shafi: made the fix generic by having the frame filtering disabled for chipsets older than AR9280.

This is going to be used for NFC sniffing. - A build fix for llc_shdlc. It fixes a build error triggered by code that's living in wireless-next. Signed-off-by:

wlcore_op_set_key() calls wl18xx_set_key(), which in turn executes some of his function calls without acquiring wl->mutex and making sure the fw is awake. Adding mutex_lock()/ps_elp_wakeup() calls is not enough, as wl18xx_set_key() calls wl1271_tx_flush() which can't be called while the mutex is taken. Add the required calls to wlcore_op_set_key, but limit the queues_stop and flushing to the only encryption types in which a spare block might be needed (GEM and TKIP).

The current elp timeout (the same as the dynamic ps timeout - 1500ms) is too high. Usually, wl1271_ps_elp_sleep() get called right after tx/rx, which is fine, but some command might get sent even when there is no traffic (e.g. ht changes triggered by beacon frames), and leaving the device awake for 1500ms in this case is redundant. Use a timeout of 30ms. The fw won't enter elp anyway before the dynamic-ps timeout was expired as well (and it entered ps successfully). Signed-off-by:

The NVS file is loaded by the device's probe callback with the help of request_firmware(). Since request_firmware() relies on udevd, the modules cannot be loaded before hotplug events are handled.

When the no_recovery flag is used, the recovery work will not restart the FW and the state will not be set to 'on'. To enable post-mortem analysis, allow memory access in the 'restarting' state. Also, since the FW might not be operational, don't fail the read/write operations if elp_wakeup fails. Reported-by:

Currently, all the (station) roles use the same keep-alive template id (0). However, the klv template ids shouldn't be shared by different roles. Implement a simple klv_templates bitmap, and let each role allocate its own klv template id on role initialization. [Arik - remove invalidation of KLV template when getting into "idle". This is already handled in unjoin] Signed-off-by:
-
Eliad Peller authored
Previously, invalidation of the keep-alive template was done when going idle. However, while removing the idle-handling we didn't move the keep-alive template invalidation to another place. This finally resulted in fw error when trying to use the keep-alive template by another role. (Note that we still have an error here - each role should have its unique keep-alive template id, while currently they all use CMD_TEMPL_KLV_IDX_NULL_DATA (0). This only works now because we don't support concurrent connected stations yet) Signed-off-by:

While recursive recovery is avoided during shutdown, a new recovery may be queued when the FW boots. The recovery work will then try to stop an already stopped hardware, which will most likely result in a kernel panic. Fix this by verifying that wl->state is on before queueing a new recovery.

Use number_of_assembled_ant5 phy param to indicate if A band is enabled: if number_of_assembled_ant5 != 0 then it is enabled otherwise it is disabled. This aligns with phy implementation that uses this param both to indicate if band is active and the number of antennas. This parameter replaces enable_11a module param that was removed. User-Space applications can use wlconf and/or INI files to disable A band using this parameter. Signed-off-by:
