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:

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:

The HWMP sequence number of received RANN element is compared to decide whether to be propagated. The sequence number is required to covert from 32bit little endian data into CPUs endianness for comparison. The same applies to the RANN metric. Signed-off-by:

When receiving DTIM we currently disable power save mode in the hardware unconditionally, i.e. also when the hardware was not sleeping. This causes trouble with at least one wireless chipset (Ralink RT3572). When the hardware is not sleeping and we send a wakeup command (e.g. this happens after a scan) then a significant decrease of the link quality or a disconnect may occur. Disabling power save mode only when it was enabled prevents this issue. Signed-off-by:

Calling mod_timer from the rx/tx hotpath is somewhat expensive, and the timeout doesn't need to be so precise. Switch to a different strategy: Schedule the timer initially, store jiffies of all last rx/tx activity which would previously modify the timer, and let the timer re-arm itself after checking the last rx/tx timestamp. Make the session timers deferrable to avoid causing extra wakeups on systems running on battery. This visibly reduces CPU load under high network load on small embedded systems. Signed-off-by:

Drivers that load firmware from their probe routine have problems with the latest versions of udev as they get timeouts while waiting for user space to start. The problem is fixed by using request_firmware_nowait() and delaying the start of mac80211 until the firmware is loaded. To prevent the possibility of the driver being unloaded while the firmware loading callback is still active, a completion queue entry is used. Also, to simplify the firmware loading procedure, this patch removes the old, unofficial and confusing fallback firmware names. However, they are still supported! So any user - who is still using them - is hereby advised to link/rename their old firmware filenames: isl3890usb to isl3886usb isl3887usb_bare to isl3887usb Signed-off-by:
