wifi: mac80211: process and save negotiated TID to Link mapping request An MLD may send TID-to-Link mapping request frame to negotiate TID to link mapping with a peer MLD. Support handling negotiated TID-to-Link mapping request frame by parsing the frame, asking the driver whether it supports the received mapping or not, and sending a TID-to-Link mapping response to the AP MLD. Theoretically, links that became inactive due to the received TID-to-Link mapping request, can be selected to be activated but this would require tearing down the negotiated TID-to-Link mapping, which is still not supported.

wifi: mac80211: add a driver callback to check active_links During ieee80211_set_active_links() we do (among the others): 1. Call drv_change_vif_links() with both old_active and new_active 2. Unassign the chanctx for the removed link(s) (if any) 3. Assign chanctx to the added link(s) (if any) 4. Call drv_change_vif_links() with the new_active links bitmap The problem here is that during step #1 the driver doesn't know whether we will activate multiple links simultaneously or are just doing a link switch, so it can't check there if multiple links are supported/enabled. (Some of the drivers might enable/disable this option dynamically) And during step #3, in which the driver already knows that, returning an error code (for example when multiple links are not supported or disabled), will cause a warning, and we will still complete the transition to the new_active links. (It is hard to undo things in that stage, since we released channels etc.) Therefore add a driver callback to check if the desired new_active links will be supported by the driver or not. This callback will be called in the beginning of ieee80211_set_active_links() so we won't do anything before we are sure it is supported.

We used to have this back until commit d260ff12e776 ("mac80211: remove vif debugfs driver callbacks") where we thought that it will be easier to just add them during interface add/remove. However, now with multi-link, we want to have proper debugfs for drivers for multi-link where some files might be in the netdev for non-MLO connections, and in the links for MLO ones, so we need to do some reconstruction when switching the mode. Moving to this new call enables that and MLO drivers will have to use it for proper debugfs operation.

mac80211: introduce individual TWT support in AP mode Introduce TWT action frames parsing support to mac80211. Currently just individual TWT agreement are support in AP mode. Whenever the AP receives a TWT action frame from an associated client, after performing sanity checks, it will notify the underlay driver with requested parameters in order to check if they are supported and if there is enough room for a new agreement. The driver is expected to set the agreement result and report it to mac80211. Drivers supporting this have two new callbacks: - add_twt_setup (mandatory) - twt_teardown_request (optional) mac80211 will send an action frame reply according to the result reported by the driver.

In order to implement support, a driver must: - call ieee80211_hw_set(hw, SUPPORTS_RX_DECAP_OFFLOAD) - implement ops->sta_set_decap_offload - mark 802.3 frames with RX_FLAG_8023 If it doesn't want to enable offload for some vif types, it can mask out IEEE80211_OFFLOAD_DECAP_ENABLED in vif->offload_flags from within the .add_interface or .update_vif_offload driver ops Signed-off-by: Felix Fietkau <nbd@nbd.name> Link: https://lore.kernel.org/r/20201218184718.93650-6-nbd@nbd.name Signed-off-by: Johannes Berg <johannes.berg@intel.com>

mac80211: rework tx encapsulation offload API The current API (which lets the driver turn on/off per vif directly) has a number of limitations: - it does not deal with AP_VLAN - conditions for enabling (no tkip, no monitor) are only checked at add_interface time - no way to indicate 4-addr support In order to address this, store offload flags in struct ieee80211_vif (easy to extend for decap offload later). mac80211 initially sets the enable flag, but gives the driver a chance to modify it before its settings are applied. In addition to the .add_interface op, a .update_vif_offload op is introduced, which can be used for runtime changes. If a driver can't disable encap offload at runtime, or if it has some extra limitations, it can simply override the flags within those ops. Support for encap offload with 4-address mode interfaces can be enabled by setting a flag from .add_interface or .update_vif_offload.

mac80211: do not call driver wake_tx_queue op during reconfig There are several scenarios in which mac80211 can call drv_wake_tx_queue after ieee80211_restart_hw has been called and has not yet completed. Driver private structs are considered uninitialized until mac80211 has uploaded the vifs, stations and keys again, so using private tx queue data during that time is not safe. The driver can also not rely on drv_reconfig_complete to figure out when it is safe to accept drv_wake_tx_queue calls again, because it is only called after all tx queues are woken again. To fix this, bail out early in drv_wake_tx_queue if local->in_reconfig is set.

mac80211: Add TXQ scheduling API This adds an API to mac80211 to handle scheduling of TXQs. The interface between driver and mac80211 for TXQ handling is changed by adding two new functions: ieee80211_next_txq(), which will return the next TXQ to schedule in the current round-robin rotation, and ieee80211_return_txq(), which the driver uses to indicate that it has finished scheduling a TXQ (which will then be put back in the scheduling rotation if it isn't empty). The driver must call ieee80211_txq_schedule_start() at the start of each scheduling session, and ieee80211_txq_schedule_end() at the end. The API then guarantees that the same TXQ is not returned twice in the same session (so a driver can loop on ieee80211_next_txq() without worrying about breaking the loop. Usage of the new API is optional, so drivers can be ported one at a time. In this patch, the actual scheduling performed by mac80211 is simple round-robin, but a subsequent commit adds airtime fairness awareness to the scheduler.

Currently, indicate the duration only for SAE authentication exchange, as SAE authentication can take up to 2000 msec (as defined in IEEE P802.11-REVmd D1.0 p. 3504).

mac80211: Add TXQ scheduling API This adds an API to mac80211 to handle scheduling of TXQs and changes the interface between driver and mac80211 for TXQ handling as follows: - The wake_tx_queue callback interface no longer includes the TXQ. Instead, the driver is expected to retrieve that from ieee80211_next_txq() - Two new mac80211 functions are added: ieee80211_next_txq() and ieee80211_schedule_txq(). The former returns the next TXQ that should be scheduled, and is how the driver gets a queue to pull packets from. The latter is called internally by mac80211 to start scheduling a queue, and the driver is supposed to call it to re-schedule the TXQ after it is finished pulling packets from it (unless the queue emptied). The ath9k and ath10k drivers are changed to use the new API. Signed-off-by: Toke Høiland-Jørgensen <toke@toke.dk> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

License cleanup: add SPDX GPL-2.0 license identifier to files with no license Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

mac80211: Add ieee80211_hw pointer to get_expected_throughput The variable is added to allow the driver an easy access to it's own hw->priv when the op is invoked. This fixes a crash in wlcore because it was relying on a station pointer that wasn't initialized yet. It's the wrong way to fix the crash, but it solves the problem for now and it does make sense to have the hw pointer here.

mac80211: synchronize driver rx queues before removing a station Some devices, like iwlwifi, have RSS queues. This may cause a situation where a disassociation is handled in control path and results in station removal while there are prior RX frames that were still not processed in other queues. When they will be processed the station will be gone, and the frames will be dropped. Add a synchronization interface to avoid that. When driver returns from the synchronization mac80211 may remove the station.

mac80211: call drv_stop only if driver is started If drv_start() fails during hw_restart, all the running interfaces are being closed/stopped, which results in drv_stop() being called, although the driver was never started successfully. This might cause drivers to perform operations on uninitialized memory (as they assume it was initialized on drv_start) Consider the local->started flag, and call the driver's stop() op only if drv_start() succeeded before. Move drv_start() and drv_stop() to driver-ops.c, as they are no longer simple wrappers.

This makes it easier to keep the hardware queues short, and to improve fairness between clients and vifs. The task of scheduling packet transmission is left up to the driver - queueing is controlled by mac80211. Drivers can only dequeue packets by calling ieee80211_tx_dequeue. This makes it possible to add active queue management later without changing drivers using this code. This can also be used as a starting point to implement A-MSDU aggregation in a way that does not add artificially induced latency.

mac80211: allow drivers to provide most station statistics In many cases, drivers can filter things like beacons that will skew statistics reported by mac80211. To get correct statistics in these cases, call drivers to obtain statistics and let them override all values, filling values from mac80211 if the driver didn't provide them. Not all of them make sense for the driver to fill, so some are still always done by mac80211. Note that this doesn't currently allow a driver to say "I know this value is wrong, don't report it at all", or to sum it up with a mac80211 value (as could be useful for "dropped misc"), that can be added if it turns out to be needed. This also gets rid of the get_rssi() method as is can now be implemented using sta_statistics(). Signed-off-by: Johannes Berg <johannes.berg@intel.com>

mac80211: add pre-RCU-sync sta removal driver operation Currently, mac80211 allows drivers to keep RCU-protected station references that are cleared when the station is removed from the driver and consequently needs to synchronize twice, once before removing the station from the driver (so it can guarantee that the station is no longer used in TX towards the driver) and once after the station is removed from the driver. Add a new pre-RCU-synchronisation station removal operation to the API to allow drivers to clear/invalidate their RCU-protected station pointers before the RCU synchronisation. This will allow removing the second synchronisation by changing the driver API so that the driver may no longer assume a valid RCU-protected pointer after sta_remove/sta_state returns. The alternative to this would be to synchronize_rcu() in all the drivers that currently rely on this behaviour (only iwlmvm) but that would defeat the purpose.

mac80211: add channel switch command and beacon callbacks The count field in CSA must be decremented with each beacon transmitted. This patch implements the functionality for drivers using ieee80211_beacon_get(). Other drivers must call back manually after reaching count == 0. This patch also contains the handling and finish worker for the channel switch command, and mac80211/chanctx code to allow to change a channel definition of an active channel context.

mac80211: move sdata debugfs dir to vif There is need create driver own per interface debugfs files. This is currently done by drv_{add,remove}_interface_debugfs() callbacks. But it is possible that after we remove interface from the driver (i.e. on suspend) we call drv_remove_interface_debugfs() function. Fixing this problem will require to add call drv_{add,remove}_interface_debugfs() anytime we create and remove interface in mac80211. So it's better to add debugfs dir dentry to vif structure to allow to create/remove custom debugfs driver files on drv_{add,remove}_interface().

mac80211: don't call bss_info_changed on p2p-device/monitor Since the idle decision rework, mac80211 started calling bss_info_changed() for the driver's monitor interface, which causes a crash for iwlwifi, but drivers generally don't expect this to happen. Therefore, avoid it. While at it, also prevent calling it in such cases and only print a warning. For the P2P Device interface the idle will no longer be called (no channel context), so also prevent that and warn on it.

Rather than adding a flag to tell userspace whether or not it can actually rely on it, simplify all the code by removing the ability to use different channel types.

One possible option would be to have the driver tell mac80211 about monitor mode queues etc., but that would duplicate the API since we already need to have queue assignments handled per virtual interface. So in order to solve this, have a virtual monitor interface that is added whenever all active vifs are monitors. We could also use the state of one of the monitor interfaces, but managing that would be complicated, so allocate separate state.

To allow the driver to replace sta_add/remove calls with this, call extra transitions with the NOTEXIST state.

Note that before this change drivers announcing driver-buffered frames in the TIM bit actually will respond to a PS-Poll with a potentially lower priority frame (if there are any frames buffered in mac80211), after this patch a driver that hasn't been changed will no longer respond at all. This only affects ath9k, which will need to be fixed to implement the new API. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

mac80211: Check for queued frames before entering power save. In a highly noisy environment, the tx rate of the driver drops and the application slows down since it has not yet received ACKs for the frames already queued in the hardware. Since this ACK may take more than 100ms, stopping the dev queues for entering PS at this stage breaks applications, WMM test cases in my testing. If there are frames already pending in the tx queue, postponing the PS logic helps to avoid redundant queue stops. When power save is enabled by default and in a noisy environment, this API certainly helps in improving the average throughput.

mac80211: track receiver's aggregation reorder buffer size The aggregation code currently doesn't implement the buffer size negotiation. It will always request a max buffer size (which is fine, if a little pointless, as the mac80211 code doesn't know and might just use 0 instead), but if the peer requests a smaller size it isn't possible to honour this request. In order to fix this, look at the buffer size in the addBA response frame, keep track of it and pass it to the driver in the ampdu_action callback when called with the IEEE80211_AMPDU_TX_OPERATIONAL action. That way the driver can limit the number of subframes in aggregates appropriately. Note that this doesn't fix any drivers apart from the addition of the new argument -- they all need to be updated separately to use this variable!

mac80211 default tx_last_beacon false (congestion) The 802.11 spec states that the STA that generated the last Beacon frame shall be the STA that response to a probe request. This is important for congestion reduction when a probe request is received - only 1 node in an adhoc BSS will transmit a response. While mac80211 drivers should provide the tx_last_beacon function to report if they transmitted the last beacon many do not. As an attempt to reduce probe response congestion default this to 0 such that a node not implementing this capability does not contribute to unnecessary congestion. In a modern medium sized office environment I see upwards of 100 probe requests per second received at a given node from various hardware/OS/drivers doing zeroconf 'active probing' as opposed to passively listening for beacons. With a modest 10-node adhoc network consisting of drivers that do not implement this tx_last_beacon feature, I have seen this result in the simultaneous xmit of probe responses accumulating to 500 probe responses per second because of collisions which brings the adhoc network to its knees as well as causes needless congestion.

mac80211: bracket driver tracing Currently, driver tracing is sometimes invoked after and sometimes before the actual driver callback. This is fine as long as the driver has no tracing itself, but as soon as it does it gets confusing. To make traces containing such information easier to read, introduce a return tracer in mac80211 that essentially brackets any driver tracing, and invoke the real trace before the driver's callback, only showing the return value, if any, afterwards. Since tracing records the process, there's no problem with overlapping calls if that should happen. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

mac80211: allow station add/remove to sleep Many drivers would like to sleep during station addition and removal, and currently have a high complexity there from not being able to. This introduces two new callbacks sta_add() and sta_remove() that drivers can implement instead of using sta_notify() and that can sleep, and the new sta_add() callback is also allowed to fail. The reason we didn't do this previously is that the IBSS code wants to insert stations from the RX path, which is a tasklet, so cannot sleep. This patch will keep the station allocation in that path, but moves adding the station to the driver out of line. Since the addition can now fail, we can have IBSS peer structs the driver rejected -- in that case we still talk to the station but never tell the driver about it in the control.sta pointer. If there will ever be a driver that has a low limit on the number of stations and that cannot talk to any stations that are not known to it, we need to do come up with a new strategy of handling larger IBSSs, maybe quicker expiry or rejecting peers.

It must be atomic because all RX code is run inside rcu critical section. Reported-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Kalle Valo <kalle.valo@iki.fi> Signed-off-by: John W.

mac80211: pass vif and station to update_tkip_key When a TKIP key is updated, we should pass the station pointer instead of just the address, since drivers can use that to store their own data. We also need to pass the virtual interface pointer. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

mac80211: annotate sleeping driver ops To make it easier to notice cases of calling sleeping ops in atomic context, annotate driver-ops.h with appropiate might_sleep() calls. At the same time, also document in mac80211.h the op functions with missing contexts. mac80211 doesn't seem to use get_tx_stats anywhere currently. Just to be on the safe side, I documented it to be atomic, but hopefully the op can be removed in the future. Compile-tested only.

mac80211: remove struct ieee80211_if_init_conf All its members (vif, mac_addr, type) are now available in the vif struct directly, so we can pass that instead of the conf struct. I generated this patch (except the mac80211 and header file changes) with this semantic patch: @@ identifier conf, fn, hw; type tp; @@ tp fn(struct ieee80211_hw *hw, -struct ieee80211_if_init_conf *conf) +struct ieee80211_vif *vif) { <...

mac80211: introduce flush operation We've long lacked a good confirmation that frames have really gone out, e.g. before going off-channel for a scan. Add a flush() operation that drivers can implement to provide that confirmation, and use it in a few places: * before scanning sends the nullfunc frames * after scanning sends the nullfunc frames, if any * when going idle, to send any pending frames Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

mac80211: reduce reliance on netdev For bluetooth 3, we will most likely not have a netdev for a virtual interface (sdata), so prepare for that by reducing the reliance on having a netdev. This patch moves the name and address fields into the sdata struct and uses them from there all over. Some work is needed to keep them sync'ed, but that's not a lot of work and in slow paths anyway. In doing so, this also reduces the number of pointer dereferences in many places, because of things like sdata->dev->dev_addr becoming sdata->vif.addr.

mac80211: convert aggregation to operate on vifs/stas The entire aggregation code currently operates on the hw pointer and station addresses, but that needs to change to make stations purely per-vif; As one step preparing for that make the aggregation code callable with the station, or by the combination of virtual interface and station address.

mac80211: remove tasklet enable/disable Due to the way the tasklets work in mac80211 there's no need to ever disable them. However, we need to clear the pending packets when taking down the last interface because otherwise the tx_pending_tasklet might be queued if the driver mucks with the queues (which it shouldn't). I've had a situation occasionally with ar9170 in which ksoftirq was using 100% CPU time because a disabled tasklet was scheduled, and I think that was due to ar9170 receiving a packet while the tasklet was disabled. That's strange and it really should not do that for other reasons, but there's no need to waste that much CPU time over it, it should just warn instead.

mac80211: allow configure_filter callback to sleep Over time, a whole bunch of drivers have come up with their own scheme to delay the configure_filter operation to a workqueue. To be able to simplify things, allow configure_filter to sleep, and add a new prepare_multicast callback that drivers that need the multicast address list implement. This new callback must be atomic, but most drivers either don't care or just calculate a hash which can be done atomically and then uploaded to the hardware non-atomically. A cursory look suggests that at76c50x-usb, ar9170, mwl8k (which is actually very broken now), rt2x00, wl1251, wl1271 and zd1211 should make use of this new capability.

cfg80211: add rfkill support To be easier on drivers and users, have cfg80211 register an rfkill structure that drivers can access. When soft-killed, simply take down all interfaces; when hard-killed the driver needs to notify us and we will take down the interfaces after the fact. While rfkilled, interfaces cannot be set UP.

mac80211: add driver ops wrappers In order to later add tracing or verifications to the driver calls mac80211 makes, this patch adds static inline wrappers for all operations. All calls are now written as drv_<op>(local, ...); instead of local->ops-><op>(&local->hw, ...); Where necessary, the wrappers also do existence checking and return default values as appropriate.
