2022-09-12wifi: rtw89: 8852c: enlarge polling timeout of RX DCKPing-Ke Shih
The range of calibration time of RX DCK is quite wide from ~40us to ~1300us by experiments, and probability is about 0.1% for the cases larger than 1000us. Though it can retry calibration and get positive result, it will spend more time. Therefore, enlarge it to avoid warning and duplicate calibration.

2022-09-07wifi: brcmfmac: Add DMI nvram filename quirk for Chuwi Hi8 Pro tabletHans de Goede
The Chuwi Hi8 Pro tablet contains quite generic names in the sys_vendor and product_name DMI strings, without this patch brcmfmac will try to load: "brcmfmac43430a0-sdio.Default string-Default string.txt" as nvram file which is way too generic. The Chuwi Hi8 Pro uses the same Ampak AP6212 module as the Chuwi Vi8 Plus and the nvram for the Vi8 Plus is already in linux-firmware, so point the new DMI nvram filename quirk to the Vi8 Plus nvram file.

2022-09-07wifi: brcmfmac: Use ISO3166 country code and rev 0 as fallback on 43430Hans de Goede
Many devices ship with a nvram ccode value of X2/XT/XU/XV/ALL which are all special world-wide compatibility ccode-s. Most of these world-wide ccode-s allow passive scan mode only for 2.4GHz channels 12-14, only enabling them when an AP is seen on them. Since linux-firmware has moved to the new cyfmac43430-sdio.bin + cyfmac43430-sdio.clm_blob firmware files this no longer works and 43430 devices using e.g. an X2 ccode fail to connect to an AP on channel 13. Add the 43430 chip-id to the list of chips for which to use the ISO3166 country code + rev 0 as fallback in brcmf_translate_country_code() to fix this.

2022-09-07wifi: iwlwifi: calib: Refactor iwl_calib_result usage for clarityKees Cook
In preparation for FORTIFY_SOURCE performing run-time destination buffer bounds checking for memcpy(), refactor the use of struct iwl_calib_result: - Have struct iwl_calib_result contain struct iwl_calib_cmd since functions expect to operate on the "data" flex array in "cmd", which follows the "hdr" member. - Switch argument passing around to use struct iwl_calib_cmd instead of struct iwl_calib_hdr to prepare functions to see the "data" member. - Change iwl_calib_set()'s "len" argument to a size_t since it is always unsigned and is normally receiving the output of sizeof(). - Add an explicit length sanity check in iwl_calib_set(). - Adjust the memcpy() to avoid copying across the now visible composite flex array structure.

2022-09-06wifi: rsi: fix kernel-doc warningJohannes Berg
One of my previous patches here changed the function prototype, but since it was (half?) automated, I didn't update the docs. Fix that now. Fixes: b3e2130bf5f6 ("wifi: mac80211: change QoS settings API to take link into account") Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-09-06wifi: mac80211_hwsim: always activate all linksJohannes Berg
By default, even in client mode, hwsim always had all links active, where it then uses them in a round-robin fashion. Re-enable that by activating all valid links work right after the connection is authorized. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-09-06wifi: mac80211: implement link switchingJohannes Berg
Implement an API function and debugfs file to switch active links. Also provide an async version of the API so drivers can call it in arbitrary contexts, e.g. while in the authorized callback. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-09-06wifi: mac80211: keep A-MSDU data in sta and per-linkBenjamin Berg
The A-MSDU data needs to be stored per-link and aggregated into a single value for the station. Add a new struct ieee_80211_sta_aggregates in order to store this data and a new function ieee80211_sta_recalc_aggregates to update the current data for the STA. Note that in the non MLO case the pointer in ieee80211_sta will directly reference the data in deflink.agg, which means that recalculation may be skipped in that case.

2022-09-06wifi: mac80211: add vif/sta link RCU dereference macrosJohannes Berg
Add macros (and an exported function) to allow checking some link RCU protected accesses that are happening in callbacks from mac80211 and are thus under the correct lock. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-09-06wifi: mac80211_hwsim: send NDP for link (de)activationJohannes Berg
In hwsim we now track when we receive NDP (or other frames carrying a PM bit) to see if a link should be active, but then of course we also need to transmit NDPs to at least set a link to inactive when we deacivate it. Implement that as well as sending an NDP when we activate a link, which allows receiving frames before transmitting any. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-09-06wifi: mac80211: extend ieee80211_nullfunc_get() for MLOJohannes Berg
Add a link_id parameter to ieee80211_nullfunc_get() to be able to obtain a correctly addressed frame. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-09-06wifi: mac80211_hwsim: track active STA linksJohannes Berg
Track the powersave bit on frames where we can look up the STA by link addresses and set the links active or inactive accordingly, and use this information to TX only on links that are actually active in the peer. Note that this doesn't implement powersave fully so if no link is active things will not work right. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-09-06wifi: mac80211_hwsim: skip inactive links on TXJohannes Berg
With the link activation handling in mac80211, skip any inactive links on TX. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-09-06wifi: mac80211: add ieee80211_find_sta_by_link_addrs APIJohannes Berg
Add a new API function ieee80211_find_sta_by_link_addrs() that looks up the STA and link ID based on interface and station link addresses. We're going to use it for mac80211-hwsim to track on the AP side which links are active. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-09-06wifi: mac80211: isolate driver from inactive linksJohannes Berg
In order to let the driver select active links and properly make multi-link connections, as a first step isolate the driver from inactive links, and set the active links to be only the association link for client-side interfaces. For AP side nothing changes since APs always have to have all their links active. To simplify things, update the for_each_sta_active_link() API to include the appropriate vif pointer. This also implies not allocating a chanctx for an inactive link, which requires a few more changes. Since we now no longer try to program multiple links to the driver, remove the check in the MLME code. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-09-06wifi: mac80211: make smps_mode per-linkBenjamin Berg
The SMPS power save mode needs to be per-link rather than being shared for all links. As such, move it into struct ieee80211_link_sta. Signed-off-by: Benjamin Berg <benjamin.berg@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2022-09-06wifi: mac80211: set link_sta in reorder timeoutJohannes Berg
Now that we have a link_sta pointer in the rx struct we also need to fill it in all the cases. It didn't matter so much until now as we weren't using it, but the code should really be able to assume that if the rx.sta is set, so is rx.link_sta.

2022-09-03wifi: mac80211_hwsim: fix multi-channel handling in netlink RXJohannes Berg
In netlink RX, now that we can actually have multiple channel contexts for MLO, things don't work well as we only keep a single pointer, and then on link switching we might NULL it, and hit the return if the channel is NULL. However, we already use mac80211_hwsim_tx_iter() which deals with all this, so remove the test and adjust the remaining code a bit. This then means we no longer use the chanctx pointer, so remove it as well. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-09-03wifi: mac80211: call drv_sta_state() under sdata_lock() in reconfigJohannes Berg
Currently, other paths calling drv_sta_state() hold the mutex and therefore drivers can assume that, and look at links with that protection. Fix that for the reconfig path as well; to do it more easily use ieee80211_reconfig_stations() for the AP/AP_VLAN station reconfig as well. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
