The initialization and copying of the RSS secret key should not use ARRAY_SIZE as we need to initialize a dword array, and not a byte array. Fix also the hook maximum write size to allow writing a longer table - up to full indirection table size. Fixes: 43413a97("iwlwifi: mvm: support rss queues configuration command") Signed-off-by:

There is still quite a bit of code using this interface, so we can't just remove it. Hopefully it will be possible in the future, but since its scheduled removal date is past 2 years already, we are better having the documentation reflecting the current state of things. Signed-off-by:

Today, the supplicant will add the RRM capabilities Information Element in the association request only if Quiet period is supported (NL80211_FEATURE_QUIET). Quiet is one of many RRM features, and there are other RRM features that are not related to Quiet (e.g. neighbor report). Therefore, requiring Quiet to enable RRM is too restrictive. Some of the features, like neighbor report, can be supported by user space without any help from the kernel. Hence adding the RRM capabilities IE to association request should be the sole user space's decision. Removing the RRM dependency on Quiet in the driver solves this problem, but using an old driver with a user space tool that would not require Quiet feature would be problematic: the user space would add NL80211_ATTR_USE_RRM in the association request even if the kernel doesn't advertize NL80211_FEATURE_QUIET and the association would be denied by the kernel. This solution adds a global RRM capability, that tells user space that it can request RRM capabilities IE publishment without any specific feature support in the kernel. Signed-off-by:

Since the PNs of all the tx keys are now tracked in the public part of the key struct (with atomic counter), we no longer need these functions. dvm and vt665{5,6} are currently the only users of these functions, so update them accordingly.

If protocol offloading is configured, the fw might generate some frames (e.g. arp response) on its own during d3/d0i3. On d3/d0i3 exit the driver queries the updated PN (if relevant), and updates its keys (for the d0i3 case, this is done by iwl_mvm_d0i3_exit_work(), which is scheduled on d0i3 exit) While in d0i3, iwlmvm defers tx frames until d0i3 exit, and then continues their processing. This is problematic with TKIP, since the frame's PN has already been set at this stage (in contrast to CCMP, where the PN is being set only later on), so both the frame's PN and the upcoming PN update (from d0i3 exit work) might be wrong. Fix it by moving the TX PN assignment (for TKIP) to the driver, similarly to CCMP. Signed-off-by:

Some drivers/devices might want to set the IVs by themselves (and still let mac80211 generate MMIC). Specifically, this is needed when the device does offloading at certain times, and the driver has to make sure that the IVs of new tx frames (from the host) are synchronized with IVs that were potentially used during the offloading. Similarly to CCMP, move the TX IVs of TKIP keys to the public part of the key struct, and export a function to add the IV right into the crypto header. The public tx_pn field is defined as atomic64, so define TKIP_PN_TO_IV16/32 helper macros to convert it to iv16/32 when needed. Since the iv32 used for the p1k cache is taken directly from the frame, we can safely remove iv16/32 from being protected by tkip.txlock. Signed-off-by:

Fix wiphy supported_band access in tx radiotap parsing introduced in commit 5ec3aed9ba4c ("mac80211: Parse legacy and HT rate in injected frames"). In particular, info->band is always set to 0 (IEEE80211_BAND_2GHZ) since it has not assigned yet. This cause a kernel crash on 5GHz only devices.

PBSS (Personal Basic Service Set) is a new BSS type for DMG networks. It is similar to infrastructure BSS, having an AP-like entity called PCP (PBSS Control Point), but it has few differences. PBSS support is mandatory for 11ad devices. Add support for PBSS by introducing a new PBSS flag attribute. The PBSS flag is used in the START_AP command to request starting a PCP instead of an AP, and in the CONNECT command to request connecting to a PCP instead of an AP. Signed-off-by:

Number of deployed 80 MHz capable VHT stations that do not support 80+80 and 160 MHz bandwidths seem to misbehave when trying to connect to an AP that advertises 80+80 or 160 MHz channel bandwidth in the VHT Operation element. To avoid such issues with deployed devices, modify the design based on recently accepted IEEE 802.11 standard changes (*). This allows poorly implemented VHT 80 MHz stations to connect with the AP in 80 MHz mode. 80+80 and 160 MHz capable stations need to support the new workaround mechanism to allow full bandwidth to be used. However, there are more or less no impacted station with 80+80/160 capability deployed. The rebased version of this patch is based on the updated version from Johannes Berg to take the HT/VHT chandef refactoring into account. (*) Changes in https://mentor.ieee.org/802.11/dcn/15/11-15-1530-04-000m-vht160-operation-signaling-through-non-zero-ccfs1.docx were accepted during the IEEE 802.11 January 2016 meeting.

If any frames are dropped that are part of a BA session, the reorder buffer will "indefinitely" (until the timeout) wait for them to come in (or a BAR moving the window) and won't release frames after them. This means it isn't possible to filter frames within a BA session in firmware. Introduce an API function that allows such filtering. Calling this function will move the BA window forward to the new SSN, and allows marking frames after the SSN as having been filtered, so any future reordering activity will release frames while skipping the holes.

This will allow drivers to make more educated decisions whether to defer transmission or not. Relying on wake_tx_queue() call count implicitly was not possible because it could be called without queued frame count actually changing on software tx aggregation start/stop code paths. It was also not possible to know how long byte-wise queue was without dequeueing. Signed-off-by:

Drivers/devices without their own rate control algorithm can get the information what rates they should use from either the radiotap header of injected frames or from the rate control algorithm. But the parsing of the legacy rate information from the radiotap header was removed in commit e6a9854b ("mac80211/drivers: rewrite the rate control API"). The removal of this feature heavily reduced the usefulness of frame injection when wanting to simulate specific transmission behavior. Having rate parsing together with MCS rates and retry support allows a fine grained selection of the tx behavior of injected frames for these kind of tests. Signed-off-by:
