2022-10-24wifi: mac80211: allow bw change during channel switch in meshHari Chandrakanthan
[ Upstream commit 6b75f133fe05c36c52d691ff21545d5757fff721 ] From 'IEEE Std 802.11-2020 section 11.8.8.4.1': The mesh channel switch may be triggered by the need to avoid interference to a detected radar signal, or to reassign mesh STA channels to ensure the MBSS connectivity. A 20/40 MHz MBSS may be changed to a 20 MHz MBSS and a 20 MHz MBSS may be changed to a 20/40 MHz MBSS. Since the standard allows the change of bandwidth during the channel switch in mesh, remove the bandwidth check present in ieee80211_set_csa_beacon.

2022-10-15wifi: mac80211: fix crash in beacon protection for P2P-deviceJohannes Berg
commit b2d03cabe2b2e150ff5a381731ea0355459be09f upstream. If beacon protection is active but the beacon cannot be decrypted or is otherwise malformed, we call the cfg80211 API to report this to userspace, but that uses a netdev pointer, which isn't present for P2P-Device. Fix this to call it only conditionally to ensure cfg80211 won't crash in the case of P2P-Device. This fixes CVE-2022-42722.

2022-10-15wifi: mac80211: fix MBSSID parsing use-after-freeJohannes Berg
commit ff05d4b45dd89b922578dac497dcabf57cf771c6 upstream. When we parse a multi-BSSID element, we might point some element pointers into the allocated nontransmitted_profile. However, we free this before returning, causing UAF when the relevant pointers in the parsed elements are accessed. Fix this by not allocating the scratch buffer separately but as part of the returned structure instead, that way, there are no lifetime issues with it. The scratch buffer introduction as part of the returned data here is taken from MLO feature work done by Ilan. This fixes CVE-2022-42719.

2022-10-15wifi: cfg80211/mac80211: reject bad MBSSID elementsJohannes Berg
commit 8f033d2becc24aa6bfd2a5c104407963560caabc upstream. Per spec, the maximum value for the MaxBSSID ('n') indicator is 8, and the minimum is 1 since a multiple BSSID set with just one BSSID doesn't make sense (the # of BSSIDs is limited by 2^n). Limit this in the parsing in both cfg80211 and mac80211, rejecting any elements with an invalid value. This fixes potentially bad shifts in the processing of these inside the cfg80211_gen_new_bssid() function later. I found this during the investigation of CVE-2022-41674 fixed by the previous patch.

2022-10-05wifi: mac80211: fix memory corruption in minstrel_ht_update_rates()Paweł Lenkow
[ Upstream commit be92292b90bfdc31f332c962882b6d3ea0285fdf ] During our testing of WFM200 module over SDIO on i.MX6Q-based platform, we discovered a memory corruption on the system, tracing back to the wfx driver. Using kfence, it was possible to trace it back to the root cause, which is hw->max_rates set to 8 in wfx_init_common, while the maximum defined by IEEE80211_TX_TABLE_SIZE is 4.

2022-10-05wifi: mac80211: fix regression with non-QoS driversHans de Goede
[ Upstream commit d873697ef2b7e1b6fdd8e9d449d9354bd5d29a4a ] Commit 10cb8e617560 ("mac80211: enable QoS support for nl80211 ctrl port") changed ieee80211_tx_control_port() to aways call __ieee80211_select_queue() without checking local->hw.queues. __ieee80211_select_queue() returns a queue-id between 0 and 3, which means that now ieee80211_tx_control_port() may end up setting the queue-mapping for a skb to a value higher then local->hw.queues if local->hw.queues is less then 4. Specifically this is a problem for ralink rt2500-pci cards where local->hw.queues is 2. There this causes rt2x00queue_get_tx_queue() to return NULL and the following error to be logged: "ieee80211 phy0: rt2x00mac_tx: Error - Attempt to send packet over invalid queue 2", after which association with the AP fails. Other callers of __ieee80211_select_queue() skip calling it when local->hw.queues < IEEE80211_NUM_ACS, add the same check to ieee80211_tx_control_port(). This fixes ralink rt2500-pci and similar cards when less then 4 tx-queues no longer working.

2022-10-05wifi: mac80211: ensure vif queues are operational after startAlexander Wetzel
commit 527008e5e87600a389feb8a57042c928ecca195d upstream. Make sure local->queue_stop_reasons and vif.txqs_stopped stay in sync. When a new vif is created the queues may end up in an inconsistent state and be inoperable: Communication not using iTXQ will work, allowing to e.g. complete the association. But the 4-way handshake will time out. The sta will not send out any skbs queued in iTXQs. All normal attempts to start the queues will fail when reaching this state. local->queue_stop_reasons will have marked all queues as operational but vif.txqs_stopped will still be set, creating an inconsistent internal state. In reality this seems to be race between the mac80211 function ieee80211_do_open() setting SDATA_STATE_RUNNING and the wake_txqs_tasklet: Depending on the driver and the timing the queues may end up to be operational or not.

2022-09-08net: Use u64_stats_fetch_begin_irq() for stats fetch.Sebastian Andrzej Siewior
commit 278d3ba61563ceed3cb248383ced19e14ec7bc1f upstream. On 32bit-UP u64_stats_fetch_begin() disables only preemption. If the reader is in preemptible context and the writer side (u64_stats_update_begin*()) runs in an interrupt context (IRQ or softirq) then the writer can update the stats during the read operation. This update remains undetected. Use u64_stats_fetch_begin_irq() to ensure the stats fetch on 32bit-UP are not interrupted by a writer. 32bit-SMP remains unaffected by this change. Cc: "David S.

2022-09-08wifi: mac80211: Fix UAF in ieee80211_scan_rx()Siddh Raman Pant
commit 60deb9f10eec5c6a20252ed36238b55d8b614a2c upstream. ieee80211_scan_rx() tries to access scan_req->flags after a null check, but a UAF is observed when the scan is completed and __ieee80211_scan_completed() executes, which then calls cfg80211_scan_done() leading to the freeing of scan_req. Since scan_req is rcu_dereference()'d, prevent the racing in __ieee80211_scan_completed() by ensuring that from mac80211's POV it is no longer accessed from an RCU read critical section before we call cfg80211_scan_done().

2022-09-08wifi: mac80211: Don't finalize CSA in IBSS mode if state is disconnectedSiddh Raman Pant
commit 15bc8966b6d3a5b9bfe4c9facfa02f2b69b1e5f0 upstream. When we are not connected to a channel, sending channel "switch" announcement doesn't make any sense. The BSS list is empty in that case. This causes the for loop in cfg80211_get_bss() to be bypassed, so the function returns NULL (check line 1424 of net/wireless/scan.c), causing the WARN_ON() in ieee80211_ibss_csa_beacon() to get triggered (check line 500 of net/mac80211/ibss.c), which was consequently reported on the syzkaller dashboard. Thus, check if we have an existing connection before generating the CSA beacon in ieee80211_ibss_finish_csa().

2022-08-17wifi: cfg80211: do some rework towards MLO link APIsJohannes Berg
[ Upstream commit 7b0a0e3c3a88260b6fcb017e49f198463aa62ed1 ] In order to support multi-link operation with multiple links, start adding some APIs. The notable addition here is to have the link ID in a new nl80211 attribute, that will be used to differentiate the links in many nl80211 operations. So far, this patch adds the netlink NL80211_ATTR_MLO_LINK_ID attribute (as well as the NL80211_ATTR_MLO_LINKS attribute) and plugs it through the system in some places, checking the validity etc. along with other infrastructure needed for it. For now, I've decided to include only the over-the-air link ID in the API. I know we discussed that we eventually need to have to have other ways of identifying a link, but for local AP mode and auth/assoc commands as well as set_key etc. we'll use the OTA ID. Also included in this patch is some refactoring of the data structures in struct wireless_dev, splitting for the first time the data into type dependent pieces, to make reasoning about these things easier.

2022-05-16mac80211: minstrel_ht: support ieee80211_rate_statusJonas Jelonek
This patch adds support for the new struct ieee80211_rate_status and its annotation in struct ieee80211_tx_status in minstrel_ht. In minstrel_ht_tx_status, a check for the presence of instances of the new struct in ieee80211_tx_status is added. Based on this, minstrel_ht then gets and updates internal rate stats with either struct ieee80211_rate_status or ieee80211_tx_info->status.rates. Adjusted variants of minstrel_ht_txstat_valid, minstrel_ht_get_stats, minstrel_{ht/vht}_get_group_idx are added which use struct ieee80211_rate_status and struct rate_info instead of the legacy structs. struct rate_info from cfg80211.h does not provide whether short preamble was used for the transmission. So we retrieve this information from VIF and STA configuration and cache it in a new flag in struct minstrel_ht_sta per rate control instance.

2022-05-16mac80211: extend current rate control tx status APIJonas Jelonek
This patch adds the new struct ieee80211_rate_status and replaces 'struct rate_info *rate' in ieee80211_tx_status with pointer and length annotation. The struct ieee80211_rate_status allows to: (1) receive tx power status feedback for transmit power control (TPC) per packet or packet retry (2) dynamic mapping of wifi chip specific multi-rate retry (mrr) chains with different lengths (3) increase the limit of annotatable rate indices to support IEEE802.11ac rate sets and beyond ieee80211_tx_info, control and status buffer, and ieee80211_tx_rate cannot be used to achieve these goals due to fixed size limitations. Our new struct contains a struct rate_info to annotate the rate that was used, retry count of the rate and tx power. It is intended for all information related to RC and TPC that needs to be passed from driver to mac80211 and its RC/TPC algorithms like Minstrel_HT. It corresponds to one stage in an mrr. Multiple subsequent instances of this struct can be included in struct ieee80211_tx_status via a pointer and a length variable. Those instances can be allocated on-stack. The former reference to a single instance of struct rate_info is replaced with our new annotation. An extension is introduced to struct ieee80211_hw. There are two new members called 'tx_power_levels' and 'max_txpwr_levels_idx' acting as a tx power level table. When a wifi device is registered, the driver shall supply all supported power levels in this list. This allows to support several quirks like differing power steps in power level ranges or alike. TPC can use this for algorithm and thus be designed more abstract instead of handling all possible step widths individually. Further mandatory changes in status.c, mt76 and ath11k drivers due to the removal of 'struct rate_info *rate' are also included. status.c already uses the information in ieee80211_tx_status->rate in radiotap, this is now changed to use ieee80211_rate_status->rate_idx. mt76 driver already uses struct rate_info to pass the tx rate to status path. The new members of the ieee80211_tx_status are set to NULL and 0 because the previously passed rate is not relevant to rate control and accurate information is passed via tx_info->status.rates. For ath11k, the txrate can be passed via this struct because ath11k uses firmware RC and thus the information does not interfere with software RC.

We currently track whether we're associated and which the BSS is in the same variable (ifmgd->associated), but for MLD we'll need to move the BSS pointer to be per link, while the question whether we're associated or not is for the whole interface. Add ifmgd->assoc_bss that stores the pointer and change ifmgd->associated to be just a bool, so the question of whether we're associated can continue working after MLD rework, without requiring changes, while the BSS pointer will have to be changed/used checked per link.

2022-05-04mac80211: Reset MBSSID parameters upon connectionManikanta Pubbisetty
Currently MBSSID parameters in struct ieee80211_bss_conf are not reset upon connection. This could be problematic with some drivers in a scenario where the device first connects to a non-transmit BSS and then connects to a transmit BSS of a Multi BSS AP. The MBSSID parameters which are set after connecting to a non-transmit BSS will not be reset and the same parameters will be passed on to the driver during the subsequent connection to a transmit BSS of a Multi BSS AP. For example, firmware running on the ath11k device uses the Multi BSS data for tracking the beacon of a non-transmit BSS and reports the driver when there is a beacon miss. If we do not reset the MBSSID parameters during the subsequent connection to a transmit BSS, then the driver would have wrong MBSSID data and FW would be looking for an incorrect BSSID in the MBSSID beacon of a Multi BSS AP and reports beacon loss leading to an unstable connection. Reset the MBSSID parameters upon every connection to solve this problem.

2022-04-11mac80211: prepare sta handling for MLO supportSriram R
Currently in mac80211 each STA object is represented using sta_info datastructure with the associated STA specific information and drivers access ieee80211_sta part of it. With MLO (Multi Link Operation) support being added in 802.11be standard, though the association is logically with a single Multi Link capable STA, at the physical level communication can happen via different advertised links (uniquely identified by Channel, operating class, BSSID) and hence the need to handle multiple link STA parameters within a composite sta_info object called the MLD STA. The different link STA part of MLD STA are identified using the link address which can be same or different as the MLD STA address and unique link id based on the link vif. To support extension of such a model, the sta_info datastructure is modified to hold multiple link STA objects with link specific params currently within sta_info moved to this new structure. Similarly this is done for ieee80211_sta as well which will be accessed within mac80211 as well as by drivers, hence trivial driver changes are expected to support this. For current non MLO supported drivers, only one link STA is present and link information is accessed via 'deflink' member. For MLO drivers, we still need to define the APIs etc. to get the correct link ID and access the correct part of the station info. Currently in mac80211, all link STA info are accessed directly via deflink. These will be updated to access via link pointers indexed by link id with MLO support patches, with link id being 0 for non MLO supported cases. Except for couple of macro related changes, below spatch takes care of updating mac80211 and driver code to access to the link STA info via deflink. @ieee80211_sta@ struct ieee80211_sta *s; struct sta_info *si; identifier var = {supp_rates, ht_cap, vht_cap, he_cap, he_6ghz_capa, eht_cap, rx_nss, bandwidth, txpwr}; @@ ( s-> - var + deflink.var | si->sta. - var + deflink.var ) @sta_info@ struct sta_info *si; identifier var = {gtk, pcpu_rx_stats, rx_stats, rx_stats_avg, status_stats, tx_stats, cur_max_bandwidth}; @@ ( si-> - var + deflink.var ) Signed-off-by: Sriram R <quic_srirrama@quicinc.com> Link: https://lore.kernel.org/r/1649086883-13246-1-git-send-email-quic_srirrama@quicinc.com [remove MLO-drivers notes from commit message, not clear yet; run spatch] Signed-off-by: Johannes Berg <johannes.berg@intel.com>
