__counted_by Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions).

2023-10-02wifi: ath10k: indicate to mac80211 scan complete with aborted flag for ↵Wen Gong
ATH10K_SCAN_STARTING state Scan failure can not be recovered from when running a loop of the following steps: 1. run scan: "iw wlan scan". 2. run command: echo soft > /sys/kernel/debug/ieee80211/phy0/ath10k/simulate_fw_crash immediately after step 1. result: scan failed and can not recover even when wlan recovery succeeds: command failed: Device or resource busy (-16) reason: When scan arrives, WMI_START_SCAN_CMDID is sent to the firmware and function ath10k_hw_scan() returns, then simulate_fw_crash arrives and the scan started event does not arrive, and then it starts to do recovery of wlan. __ath10k_scan_finish() which is called from ath10k_halt() is one step of recovery, it will not call ieee80211_scan_completed() by logic currently because the scan state is ATH10K_SCAN_STARTING. Thus it leads the scan not being completed in mac80211, and leads all consecutive scans failing with -EBUSY in nl80211_trigger_scan even after wlan recovery success. Indicate scan complete with aborted flag to mac80211 for ATH10K_SCAN_STARTING to allow recovery from scan failed with "Device or resource busy (-16)" after wlan recovery.

2023-10-02wifi: ath: dfs_pattern_detector: Use flex array to simplify codeChristophe JAILLET
At the time of the writing, the value of 'num_radar_types' is 7 or 9. So on a 64 bits system, only 56 or 72 bytes are allocated for the 'detectors' array. Turn it into a flex array, in order to simplify memory management and save an indirection when the array is used. Doing so, cd->detectors can't be NULL, and channel_detector_exit() can be simplified as well.

2023-10-02wifi: ath10k: Don't touch the CE interrupt registers after power upDouglas Anderson
As talked about in commit d66d24ac300c ("ath10k: Keep track of which interrupts fired, don't poll them"), if we access the copy engine register at a bad time then ath10k can go boom. However, it's not necessarily easy to know when it's safe to access them. The ChromeOS test labs saw a crash that looked like this at shutdown/reboot time (on a chromeos-5.15 kernel, but likely the problem could also reproduce upstream): Internal error: synchronous external abort: 96000010 [#1] PREEMPT SMP ...

Let's fix this by changing how we "disable" the interrupts. Instead of tweaking the copy engine registers we'll just use disable_irq() and enable_irq(). Then we'll configure the interrupts once at power up time.

2023-10-02wifi: ath12k: add keep backward compatibility of PHY mode to avoid firmware ↵Wen Gong
crash In a special WCN7855 firmware release the EHT (IEEE 802.11be) support has been disabled for size reduction. Currently ath12k always enables EHT PHY mode during vdev start but with the special firmware that will cause a firmware crash during vdev start in firmware initialisation. This is because the firmware will use the EHT mode to allocate resources but as the EHT mode is not available in the firmware, there's an internal conflict and the firmware will crash. To fix the crash check the WMI_TLV_SERVICE_11BE flag to see if the firmware supports EHT. If EHT is not supported downgrade the PHY mode to HE (IEEE 802.11ax). This does not impact QCN9274, because WMI_SERVICE_11BE is always enabled for QCN9274, then eht_cap->has_eht will always set for it, and the logic of this patch will not take effect and the PHY mode will not down grade for it.

2023-10-02wifi: ath12k: do not drop data frames from unassociated stationsHari Chandrakanthan
>From 'IEEE Std 802.11-2020 section 11.3.4.1': If STA A in an infrastructure BSS receives a Class 2 or Class 3 frame from STA B that is not authenticated with STA A (i.e., the state for STA B is State 1), STA A shall discard the frame. If the frame has an individual address in the Address 1 field, the MLME of STA A shall send a Deauthentication frame to STA B. When data frames from unassociated stations are received by an AP, the AP is supposed to send a deauthentication/disassociation frame with reason code "Class 2 frame received from nonauthenticated STA" or "Class 3 frame received from nonassociated STA". But ath12k AP doesn't send deauthentication/disassociation frames, when it receives data frames from unassociated stations. The ath12k driver drops the data frames from unassociated station and the upper layer(mac80211/hostapd) is not aware of such event. Hence deauthentication/disassociation frame is not sent to that particular station by the AP. To address this issue, allow the data frames from the unassociated stations to reach mac80211 so that mac80211 can send NL80211_CMD_UNEXPECTED_FRAME event to userspace(hostapd) and hostapd upon receiving the event will send the deauthentication/disassociation frame with proper reason code. The data frame from unassociated stations gets dropped in mac80211.

2023-10-02sky2: Make sure there is at least one frag_addr availableKees Cook
In the pathological case of building sky2 with 16k PAGE_SIZE, the frag_addr[] array would never be used, so the original code was correct that size should be 0. But the compiler now gets upset with 0 size arrays in places where it hasn't eliminated the code that might access such an array (it can't figure out that in this case an rx skb with fragments would never be created). To keep the compiler happy, make sure there is at least 1 frag_addr in struct rx_ring_info: In file included from include/linux/skbuff.h:28, from include/net/net_namespace.h:43, from include/linux/netdevice.h:38, from drivers/net/ethernet/marvell/sky2.c:18: drivers/net/ethernet/marvell/sky2.c: In function 'sky2_rx_unmap_skb': include/linux/dma-mapping.h:416:36: warning: array subscript i is outside array bounds of 'dma_addr_t[0]' {aka 'long long unsigned int[]'} [-Warray-bounds=] 416 | #define dma_unmap_page(d, a, s, r) dma_unmap_page_attrs(d, a, s, r, 0) | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/net/ethernet/marvell/sky2.c:1257:17: note: in expansion of macro 'dma_unmap_page' 1257 | dma_unmap_page(&pdev->dev, re->frag_addr[i], | ^~~~~~~~~~~~~~ In file included from drivers/net/ethernet/marvell/sky2.c:41: drivers/net/ethernet/marvell/sky2.h:2198:25: note: while referencing 'frag_addr' 2198 | dma_addr_t frag_addr[ETH_JUMBO_MTU >> PAGE_SHIFT]; | ^~~~~~~~~ With CONFIG_PAGE_SIZE_16KB=y, PAGE_SHIFT == 14, so: #define ETH_JUMBO_MTU 9000 causes "ETH_JUMBO_MTU >> PAGE_SHIFT" to be 0.

2023-10-02net: dsa: mv88e6xxx: Avoid EEPROM timeout when EEPROM is absentFabio Estevam
Since commit 23d775f12dcd ("net: dsa: mv88e6xxx: Wait for EEPROM done before HW reset") the following error is seen on a imx8mn board with a 88E6320 switch: mv88e6085 30be0000.ethernet-1:00: Timeout waiting for EEPROM done This board does not have an EEPROM attached to the switch though. This problem is well explained by Andrew Lunn: "If there is an EEPROM, and the EEPROM contains a lot of data, it could be that when we perform a hardware reset towards the end of probe, it interrupts an I2C bus transaction, leaving the I2C bus in a bad state, and future reads of the EEPROM do not work. The work around for this was to poll the EEInt status and wait for it to go true before performing the hardware reset. However, we have discovered that for some boards which do not have an EEPROM, EEInt never indicates complete. As a result, mv88e6xxx_g1_wait_eeprom_done() spins for a second and then prints a warning. We probably need a different solution than calling mv88e6xxx_g1_wait_eeprom_done(). The datasheet for 6352 documents the EEPROM Command register: bit 15 is: EEPROM Unit Busy. This bit must be set to a one to start an EEPROM operation (see EEOp below). Only one EEPROM operation can be executing at one time so this bit must be zero before setting it to a one. When the requested EEPROM operation completes this bit will automatically be cleared to a zero. The transition of this bit from a one to a zero can be used to generate an interrupt (the EEInt in Global 1, offset 0x00). and more interesting is bit 11: Register Loader Running. This bit is set to one whenever the register loader is busy executing instructions contained in the EEPROM." Change to using mv88e6xxx_g2_eeprom_wait() to fix the timeout error when the EEPROM chip is not present.
