2022-08-09wifi: ath10k: add peer map clean up for peer delete in ath10k_sta_state()Wen Gong1-25/+29
When peer delete failed in a disconnect operation, use-after-free detected by KFENCE in below log. It is because for each vdev_id and address, it has only one struct ath10k_peer, it is allocated in ath10k_peer_map_event(). When connected to an AP, it has more than one HTT_T2H_MSG_TYPE_PEER_MAP reported from firmware, then the array peer_map of struct ath10k will be set muti-elements to the same ath10k_peer in ath10k_peer_map_event(). When peer delete failed in ath10k_sta_state(), the ath10k_peer will be free for the 1st peer id in array peer_map of struct ath10k, and then use-after-free happened for the 2nd peer id because they map to the same ath10k_peer. And clean up all peers in array peer_map for the ath10k_peer, then user-after-free disappeared peer map event log: [ 306.911021] wlan0: authenticate with b0:2a:43:e6:75:0e [ 306.957187] ath10k_pci 0000:01:00.0: mac vdev 0 peer create b0:2a:43:e6:75:0e (new sta) sta 1 / 32 peer 1 / 33 [ 306.957395] ath10k_pci 0000:01:00.0: htt peer map vdev 0 peer b0:2a:43:e6:75:0e id 246 [ 306.957404] ath10k_pci 0000:01:00.0: htt peer map vdev 0 peer b0:2a:43:e6:75:0e id 198 [ 306.986924] ath10k_pci 0000:01:00.0: htt peer map vdev 0 peer b0:2a:43:e6:75:0e id 166 peer unmap event log: [ 435.715691] wlan0: deauthenticating from b0:2a:43:e6:75:0e by local choice (Reason: 3=DEAUTH_LEAVING) [ 435.716802] ath10k_pci 0000:01:00.0: mac vdev 0 peer delete b0:2a:43:e6:75:0e sta ffff990e0e9c2b50 (sta gone) [ 435.717177] ath10k_pci 0000:01:00.0: htt peer unmap vdev 0 peer b0:2a:43:e6:75:0e id 246 [ 435.717186] ath10k_pci 0000:01:00.0: htt peer unmap vdev 0 peer b0:2a:43:e6:75:0e id 198 [ 435.717193] ath10k_pci 0000:01:00.0: htt peer unmap vdev 0 peer b0:2a:43:e6:75:0e id 166 use-after-free log: [21705.888627] wlan0: deauthenticating from d0:76:8f:82:be:75 by local choice (Reason: 3=DEAUTH_LEAVING) [21713.799910] ath10k_pci 0000:01:00.0: failed to delete peer d0:76:8f:82:be:75 for vdev 0: -110 [21713.799925] ath10k_pci 0000:01:00.0: found sta peer d0:76:8f:82:be:75 (ptr 0000000000000000 id 102) entry on vdev 0 after it was supposedly removed [21713.799968] ================================================================== [21713.799991] BUG: KFENCE: use-after-free read in ath10k_sta_state+0x265/0xb8a [ath10k_core] [21713.799991] [21713.799997] Use-after-free read at 0x00000000abe1c75e (in kfence-#69): [21713.800010] ath10k_sta_state+0x265/0xb8a [ath10k_core] [21713.800041] drv_sta_state+0x115/0x677 [mac80211] [21713.800059] __sta_info_destroy_part2+0xb1/0x133 [mac80211] [21713.800076] __sta_info_flush+0x11d/0x162 [mac80211] [21713.800093] ieee80211_set_disassoc+0x12d/0x2f4 [mac80211] [21713.800110] ieee80211_mgd_deauth+0x26c/0x29b [mac80211] [21713.800137] cfg80211_mlme_deauth+0x13f/0x1bb [cfg80211] [21713.800153] nl80211_deauthenticate+0xf8/0x121 [cfg80211] [21713.800161] genl_rcv_msg+0x38e/0x3be [21713.800166] netlink_rcv_skb+0x89/0xf7 [21713.800171] genl_rcv+0x28/0x36 [21713.800176] netlink_unicast+0x179/0x24b [21713.800181] netlink_sendmsg+0x3a0/0x40e [21713.800187] sock_sendmsg+0x72/0x76 [21713.800192] ____sys_sendmsg+0x16d/0x1e3 [21713.800196] ___sys_sendmsg+0x95/0xd1 [21713.800200] __sys_sendmsg+0x85/0xbf [21713.800205] do_syscall_64+0x43/0x55 [21713.800210] entry_SYSCALL_64_after_hwframe+0x44/0xa9 [21713.800213] [21713.800219] kfence-#69: 0x000000009149b0d5-0x000000004c0697fb, size=1064, cache=kmalloc-2k [21713.800219] [21713.800224] allocated by task 13 on cpu 0 at 21705.501373s: [21713.800241] ath10k_peer_map_event+0x7e/0x154 [ath10k_core] [21713.800254] ath10k_htt_t2h_msg_handler+0x586/0x1039 [ath10k_core] [21713.800265] ath10k_htt_htc_t2h_msg_handler+0x12/0x28 [ath10k_core] [21713.800277] ath10k_htc_rx_completion_handler+0x14c/0x1b5 [ath10k_core] [21713.800283] ath10k_pci_process_rx_cb+0x195/0x1df [ath10k_pci] [21713.800294] ath10k_ce_per_engine_service+0x55/0x74 [ath10k_core] [21713.800305] ath10k_ce_per_engine_service_any+0x76/0x84 [ath10k_core] [21713.800310] ath10k_pci_napi_poll+0x49/0x144 [ath10k_pci] [21713.800316] net_rx_action+0xdc/0x361 [21713.800320] __do_softirq+0x163/0x29a [21713.800325] asm_call_irq_on_stack+0x12/0x20 [21713.800331] do_softirq_own_stack+0x3c/0x48 [21713.800337] __irq_exit_rcu+0x9b/0x9d [21713.800342] common_interrupt+0xc9/0x14d [21713.800346] asm_common_interrupt+0x1e/0x40 [21713.800351] ksoftirqd_should_run+0x5/0x16 [21713.800357] smpboot_thread_fn+0x148/0x211 [21713.800362] kthread+0x150/0x15f [21713.800367] ret_from_fork+0x22/0x30 [21713.800370] [21713.800374] freed by task 708 on cpu 1 at 21713.799953s: [21713.800498] ath10k_sta_state+0x2c6/0xb8a [ath10k_core] [21713.800515] drv_sta_state+0x115/0x677 [mac80211] [21713.800532] __sta_info_destroy_part2+0xb1/0x133 [mac80211] [21713.800548] __sta_info_flush+0x11d/0x162 [mac80211] [21713.800565] ieee80211_set_disassoc+0x12d/0x2f4 [mac80211] [21713.800581] ieee80211_mgd_deauth+0x26c/0x29b [mac80211] [21713.800598] cfg80211_mlme_deauth+0x13f/0x1bb [cfg80211] [21713.800614] nl80211_deauthenticate+0xf8/0x121 [cfg80211] [21713.800619] genl_rcv_msg+0x38e/0x3be [21713.800623] netlink_rcv_skb+0x89/0xf7 [21713.800628] genl_rcv+0x28/0x36 [21713.800632] netlink_unicast+0x179/0x24b [21713.800637] netlink_sendmsg+0x3a0/0x40e [21713.800642] sock_sendmsg+0x72/0x76 [21713.800646] ____sys_sendmsg+0x16d/0x1e3 [21713.800651] ___sys_sendmsg+0x95/0xd1 [21713.800655] __sys_sendmsg+0x85/0xbf [21713.800659] do_syscall_64+0x43/0x55 [21713.800663] entry_SYSCALL_64_after_hwframe+0x44/0xa9 Tested-on: QCA6174 hw3.2 PCI WLAN.RM.4.4.1-00288-QCARMSWPZ-1 Fixes: d0eeafad1189 ("ath10k: Clean up peer when sta goes away.")

2022-08-09wifi: ath10k: Set tx credit to one for WCN3990 snoc based devicesYoughandhar Chintala3-3/+26
Currently host can send two WMI commands at once. There is possibility to cause SMMU issues or corruption, if host wants to initiate 2 DMA transfers, it is possible when copy complete interrupt for first DMA reaches host, CE has already updated SRRI (Source ring read index) for both DMA transfers and is in the middle of 2nd DMA. Host uses SRRI (Source ring read index) to interpret how many DMA’s have been completed and tries to unmap/free both the DMA entries. Hence now it is limiting to one.Because CE is still in the middle of 2nd DMA which can cause these issues when handling two DMA transfers. This change will not impact other targets, as it is only for WCN3990.

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: - Runtime verification infrastructure This is the biggest change here. It introduces the runtime verification that is necessary for running Linux on safety critical systems. It allows for deterministic automata models to be inserted into the kernel that will attach to tracepoints, where the information on these tracepoints will move the model from state to state. If a state is encountered that does not belong to the model, it will then activate a given reactor, that could just inform the user or even panic the kernel (for which safety critical systems will detect and can recover from). - Two monitor models are also added: Wakeup In Preemptive (WIP - not to be confused with "work in progress"), and Wakeup While Not Running (WWNR). - Added __vstring() helper to the TRACE_EVENT() macro to replace several vsnprintf() usages that were all doing it wrong. - eprobes now can have their event autogenerated when the event name is left off. - The rest is various cleanups and fixes. * tag 'trace-v6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (50 commits) rv: Unlock on error path in rv_unregister_reactor() tracing: Use alignof__(struct {type b;}) instead of offsetof() tracing/eprobe: Show syntax error logs in error_log file scripts/tracing: Fix typo 'the the' in comment tracepoints: It is CONFIG_TRACEPOINTS not CONFIG_TRACEPOINT tracing: Use free_trace_buffer() in allocate_trace_buffers() tracing: Use a struct alignof to determine trace event field alignment rv/reactor: Add the panic reactor rv/reactor: Add the printk reactor rv/monitor: Add the wwnr monitor rv/monitor: Add the wip monitor rv/monitor: Add the wip monitor skeleton created by dot2k Documentation/rv: Add deterministic automata instrumentation documentation Documentation/rv: Add deterministic automata monitor synthesis documentation tools/rv: Add dot2k Documentation/rv: Add deterministic automaton documentation tools/rv: Add dot2c Documentation/rv: Add a basic documentation rv/include: Add instrumentation helper functions rv/include: Add deterministic automata monitor definition via C macros ...

The naming of the get/set/clear firmware feature capability bits doesn't really follow the established namespace pattern of wcn36xx_logicalblock_do_something(); The feature bits are accessed by smd.c and main.c. It would be nice to display the found feature bits in debugfs. To do so though we should tidy up the namespace a bit.

2022-07-27wifi: ath11k: Fix register write failure on QCN9074Manikanta Pubbisetty6-69/+128
Commit 56c8ccf331bd ("ath11k: Add register access logic for WCN6750") regressed QCN9074. With the above mentioned commit, writes are failing for some registers on QCN9074 although the device seems to work normally. ath11k_pci 0000:03:00.0: failed to set pcie link register0x01e0e0a8: 0xffffffff != 0x00000010 ath11k_pci 0000:03:00.0: failed to set sysclk: -110 PCIe devices in ath11k (QCA6390, WCN6855, QCN9074, WCN6750) use window concept for register accesses. There are two schemes, dynamic & static window. In dynamic window scheme, a single window(region in the BAR) is mapped either to CE or DP register windows at any give time. QCA6390 & WCN6855 follow this scheme for register accesses. In static window scheme, CE & DP register windows are statically mapped to separate regions with in the BAR so that there is no switching of register windows between CE & DP register accesses. QCN9074 & WCN6750 follow this scheme although the window start offsets are different for QCN9074 & WCN6750. QCN9074 uses 3rd & 2nd window for DP & CE register accesses respectively whereas WCN6750 uses 1st & 2nd window for DP & CE. In QCN9074, along with 2nd & 3rd windows, 1st window is also used for certain configurations which commit 56c8ccf331bd ("ath11k: Add register access logic for WCN6750") did not account for and hence the regression. Fix this by going back to the original way of accessing the registers on QCN9074. Since this diverges from WCN6750 way of accessing registers, it is required to register window_read32/window_write32() pci_ops for WCN6750. We can also get rid of dp_window_idx & ce_window_idx members in hw_params, so remove them. Also add a new API ath11k_pcic_register_pci_ops() for registering pci_ops to the ath11k core. This API checks for mandatory pci_ops() and reports error if those are missing. Also initialize unused pci_ops to NULL.

The MLO links used for connection with an MLD AP are decided by the driver in case of SME offloaded to driver. Add support for the drivers to indicate the information of links used for MLO connection in connect and roam callbacks, update the connected links information in wdev from connect/roam result sent by driver. Also, send the connected links information to userspace. Add a netlink flag attribute to indicate that userspace supports handling of MLO connection. Drivers must not do MLO connection when this flag is not set. This is to maintain backwards compatibility with older supplicant versions which doesn't have support for MLO connection.

2022-06-20wifi: cfg80211: do some rework towards MLO link APIsJohannes Berg2-6/+9
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.

2022-06-06ath11k: Fix LDPC config in set_bitrate_mask hookManikanta Pubbisetty2-3/+3
Currently ar->ht_cap_info is not set anywhere in the code, this could result in LDPC config computed wrongly in the set_bitrate_mask() hook and eventually sending wrong config to the target. Fix this by checking the LDPC support from the band HT capabilities of the radio instead. Furthermore, it looks like firmwares running on the ath11k hardware do not set WMI_HT_CAP_LDPC for advertising the TX LDPC capability, WMI_HT_CAP_TX_LDPC is set instead and this should be checked for getting hardware's TX LDPC support. This is true for QCA6390, WCN6855 & WCN6750 hardware. Also, remove unused variables ht_cap_info & vht_cap_info from struct ath11k{}. Found this during code review.

2022-06-06ath11k: Avoid REO CMD failed prints during firmware recoveryManikanta Pubbisetty1-2/+3
Currently when firmware recovery is in progress, we do not queue REO commands to the firmware, instead -ESHUTDOWN will be returned to the caller leading to a failure print on the console. The REO command in the problem scenario is sent for all tids of a peer in which case we will have 16 failure prints on the console for a single peer. For an AP usecase, this count would be even higher in a worst case scenario. Since these commands are bound to fail during firmware recovery, it is better to avoid printing these failures and thereby avoid message flooding on the console.

It leads inconsistent values between global and phy#0 as below. global country KR: DFS-JP (2402 - 2482 @ 40), (N/A, 13), (N/A) (5170 - 5250 @ 80), (N/A, 20), (N/A), AUTO-BW (5250 - 5330 @ 80), (N/A, 20), (0 ms), DFS, AUTO-BW (5490 - 5710 @ 160), (N/A, 30), (0 ms), DFS (5735 - 5835 @ 80), (N/A, 30), (N/A) (57000 - 66000 @ 2160), (N/A, 43), (N/A) phy#0 country US: DFS-FCC (2400 - 2472 @ 40), (N/A, 30), (N/A) (5150 - 5250 @ 80), (N/A, 23), (N/A), AUTO-BW (5250 - 5350 @ 80), (N/A, 23), (0 ms), DFS, AUTO-BW (5470 - 5730 @ 160), (N/A, 23), (0 ms), DFS (5730 - 5850 @ 80), (N/A, 30), (N/A) (57240 - 71000 @ 2160), (N/A, 40), (N/A) The initial reg code is 0x6C which saved in reg_world_copy of ath_common, and the code US is updated from cfg80211 later, so ath10k should also check the initial reg code before regulatory_hint(). After this fix, regdomain info is same between "iw reg get" and "iw reg set xx", it does not have the regdomain info of phy#0 again. global country KR: DFS-JP (2402 - 2482 @ 40), (N/A, 13), (N/A) (5170 - 5250 @ 80), (N/A, 20), (N/A), AUTO-BW (5250 - 5330 @ 80), (N/A, 20), (0 ms), DFS, AUTO-BW (5490 - 5710 @ 160), (N/A, 30), (0 ms), DFS (5735 - 5835 @ 80), (N/A, 30), (N/A) (57000 - 66000 @ 2160), (N/A, 43), (N/A) This does not effect the channel list and power which ath10k used. When the country code for regulatory_hint() in ath10k_mac_register() is same with the global country code, then reg_set_rd_driver() of cfg80211 called from crda which return -EALREADY to set_regdom() and then update_all_wiphy_regulatory() will not be called while wlan load. When run "iw reg set xx", reg_get_regdomain() which used by function handle_channel() in net/wirelss/reg.c always use the regdomain returned by get_cfg80211_regdom() because the initiator of last regulatory_request is NL80211_REGDOM_SET_BY_USER, get_cfg80211_regdom() is the global regdomain, then all the ieee80211_channel info is updated in handle_channel() with the global regdomain.

2022-05-30ath11k: support avg signal in station dumpThiraviyam Mariyappan3-0/+12
Currently mac80211 doesn't calculate average signal when RSS(Receive side scaling) is enabled from the driver, so average signal isn't printed in the station dump. To address this issue, calculate the average signal from RSSI within driver and display in the station dump.
