Create a new small wl12xx module that only contains the probe functions and depends entirely on wlcore otherwise. Signed-off-by:Luciano Coelho <coelho@ti.com>

Rename the wl12xx driver directory to wlcore as an initial step towards the split of the driver into wlcore and wl12xx. We just rename the directory first to keep git blame happy. Signed-off-by: -

In certain scenarios involving sched scan + normal scan + COEX scan could take longer than 10s and this triggers a recovery where it shouldn't. Increase the timeout to avoid that. Signed-off-by:

Set the dwell times for sched scan according to the number of probe requests which are going to be transmitted. This should fix the too short dwell time problem which prevented some of the probe requests from being transmitted in cases of high number of SSIDs (10+) to be actively sched scanned. However, in the common case of having up to 1-2 SSIDs that require active scan, the dwell time would be kept to a minimum which should conserve power. This is important as sched scan also runs periodically while the host is suspended and there's great importance to keep power consumption as low as possible. Signed-off-by:

wlvif->probereq is zeroed when adding an interface but the skb pointed to isn't freed when the interface is removed. This would lead to a mem leak on every recovery. Fix it by freeing the skb when removing the interface. Signed-off-by:

The iteration on the wlvif list in wl1271_op_resume/suspend was perfomed before locking wl->mutex which would lead to a kernel panic in case a recovery was queued at the same time and would delete the wlvifs from the list. Signed-off-by:

wl12xx sets the do_join flag (which later starts the sta role) when the bssid was changed and the sta is associated. However, this no longer happens after the "mac80211: remove spurious BSSID change flag" patch. Fix it by setting the do_join flag on BSS_CHANGED_ASSOC (for IBSS, do_join is already set on BSS_CHANGED_IBSS) Signed-off-by:

Move the POWER_PMI to the op_mode where it is changed. The trans needs to check it frequently, so shadow the status in the trans and update it in trans when it infrequently changes. Signed-off-by:

This variable holds the ucode currently running on the device; which is determined by op_mode, so move this parameter there. Also, the name of the variable is a bit misleading, so rename it to cur_ucode. Signed-off-by:

Error log reporting does not belong to the transport layer, but to the op_mode loading the ucode, as it is the entity which knows about the ucode loaded, and what the error information means. Move device logging pointers from the transport layer to op_mode. With this change, transport layer only reports an error to the op_mode, which will figure out what to do with the error. This causes the driver to now dump out error logs when the command queue is stuck as well. Also, move the debugfs entry for event logs out of the transport layer and into op_mode. Signed-off-by:

The queue mapping is not only dynamic, it is also dependent on the uCode, as we can already see today with the dual-mode and non-dual-mode being different. Move the queue mapping out of the transport layer and let the higher layer manage it. Part of the transport configuration is how to set up the queues. Signed-off-by:

As idle is just a deep powersave mode for the device, it will easily scan while idle since that turns off powersave. This reduces the number of commands sent to the device when scanning. Signed-off-by:

The calibration results all come in while we're waiting for the calibration complete notification. As a consequence, there's no need to install a global RX handler for them, we can use the newly extended notification wait framework for this and make the code easier to follow. It is now quite explicit that we are processing the calibration results while waiting for the complete notification, before this was implicit and developers had to know this to understand why we wait for the calibration complete notification and what happens while we wait. Signed-off-by:

Johannes Berg authored
Sometimes, for example when we ask the uCode for calibration, we wait for the "complete" response while we also need the results that are sent in other, interim, notifications. Currently we handle this by installing an RX handler globally, but that isn't needed as this is the only time we want to use these notifications. So in order to be able to simplify at least future code that does the same, extend the notification wait framework to allow you to wait for multiple commands and decide based on the command whether the wait finished. While at it, also fix a race that can then become relevant -- if the wait function has returned true once it shouldn't be called again, today this can happen due to races between the triggering and the wakeup.

The flow handler (hardware) can put multiple frames into a single RX buffer. To handle this, walk the RX buffer and check if there are multiple valid packets in it. To let the upper layer handle this correctly introduce rxb_offset() which is needed when we pass pages to mac80211 -- we need to know the offset into the page there. Also change the page handling scheme to use refcounting. Anyone who needs a page will "steal" it, which marks it as having been used & refcounts it. The RX handler then has to free its own reference and must not reuse the page. Finally, do not set the bit asking the FH to give us each packet in a single buffer. This really enables the feature.

It has happened twice now where elaborate troubleshooting has undergone on systems where CONFIG_CFG80211_INTERNAL_REGDB [0] has been set but yet net/wireless/db.txt was not updated. Despite the documentation on this it seems system integrators could use some more help with this, so throw out a kernel warning at boot time when their database is empty. This does mean that the error-prone system integrator won't likely realize the issue until they boot the machine but -- it does not seem to make sense to enable a build bug breaking random build testing.

This patch is intended to solve the follwing issues in RANN propagation: [1] The interval in propagated RANN should be based on the interval of received RANN. [2] The aggregated path metric for propagated RANN is as received plus own link metric towards the transmitting mesh STA (not root mesh STA). [3] The comparison of path metric for RANN with same sequence number should be done before deciding whether to propagate or not. Signed-off-by:Chun-Yeow Yeoh <yeohchunyeow@gmail.com> Signed-off-by:

The current version of rtlwifi for USB operations uses kmalloc to acquire a 32-bit buffer for each read of the device. When _usb_read_sync() is called with the rcu_lock held, the result is a "sleeping function called from invalid context" BUG. This is reported for two cases in https://bugzilla.kernel.org/show_bug.cgi?id=42775. The first case has the lock originating from within rtlwifi and could be fixed by rearranging the locking; however, the second originates from within mac80211. The kmalloc() call is removed from _usb_read_sync() by creating a ring buffer pointer in the private area and allocating the buffer data in the probe routine. Signed-off-by:
