2023-02-24wifi: wcn36xx: Slightly optimize PREPARE_HAL_BUF()Christophe JAILLET
In most (likely all) cases, INIT_HAL_MSG() is called before PREPARE_HAL_BUF(). In such cases calling memset() is useless because: msg_body.header.len = sizeof(msg_body) So, instead of writing twice the memory, we just have a sanity check to make sure that some potential trailing memory is zeroed. It even gives the opportunity to see that by itself and optimize it away.

2023-02-22wifi: ath11k: allow system suspend to survive ath11kLen Brown
When ath11k runs into internal errors upon suspend, it returns an error code to pci_pm_suspend, which aborts the entire system suspend. The driver should not abort system suspend, but should keep its internal errors to itself, and allow the system to suspend. Otherwise, a user can suspend a laptop by closing the lid and sealing it into a case, assuming that is will suspend, rather than heating up and draining the battery when in transit. In practice, the ath11k device seems to have plenty of transient errors, and subsequent suspend cycles after this failure often succeed. https://bugzilla.kernel.org/show_bug.cgi?id=216968 Fixes: d1b0c33850d29 ("ath11k: implement suspend for QCA6390 PCI devices") Signed-off-by: Len Brown <len.brown@intel.com> Cc: stable@vger.kernel.org Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20230201183201.14431-1-len.brown@intel.com

2023-02-22wifi: ath10k: snoc: enable threaded napi on WCN3990Abhishek Kumar
NAPI poll can be done in threaded context along with soft irq context. Threaded context can be scheduled efficiently, thus creating less of bottleneck during Rx processing. This patch is to enable threaded NAPI on ath10k driver. Based on testing, it was observed that on WCN3990, the CPU0 reaches 100% utilization when napi runs in softirq context. At the same time the other CPUs are at low consumption percentage. This does not allow device to reach its maximum throughput potential. After enabling threaded napi, CPU load is balanced across all CPUs and following improvments were observed: - UDP_RX increase by ~22-25% - TCP_RX increase by ~15% Here are some of the additional raw data with and without threaded napi: ================================================== udp_rx(Without threaded NAPI) 435.98+-5.16 : Channel 44 439.06+-0.66 : Channel 157 udp_rx(With threaded NAPI) 509.73+-41.03 : Channel 44 549.97+-7.62 : Channel 157 =================================================== udp_tx(Without threaded NAPI) 461.31+-0.69 : Channel 44 461.46+-0.78 : Channel 157 udp_tx(With threaded NAPI) 459.20+-0.77 : Channel 44 459.78+-1.08 : Channel 157 =================================================== tcp_rx(Without threaded NAPI) 472.63+-2.35 : Channel 44 469.29+-6.31 : Channel 157 tcp_rx(With threaded NAPI) 498.49+-2.44 : Channel 44 541.14+-40.65 : Channel 157 =================================================== tcp_tx(Without threaded NAPI) 317.34+-2.37 : Channel 44 317.01+-2.56 : Channel 157 tcp_tx(With threaded NAPI) 371.34+-2.36 : Channel 44 376.95+-9.40 : Channel 157 =================================================== Tested-on: WCN3990 hw1.0 SNOC WLAN.HL.3.2.2-00696-QCAHLSWMTPL-1 Signed-off-by: Abhishek Kumar <kuabhs@chromium.org> Signed-off-by: Kalle Valo <quic_kvalo@quicinc.com> Link: https://lore.kernel.org/r/20230203000116.v2.1.I5bb9c164a2d2025655dee810b983e01ecd81c14e@changeid

2023-02-20wifi: ath9k: hif_usb: fix memory leak of remain_skbsFedor Pchelkin
hif_dev->remain_skb is allocated and used exclusively in ath9k_hif_usb_rx_stream(). It is implied that an allocated remain_skb is processed and subsequently freed (in error paths) only during the next call of ath9k_hif_usb_rx_stream(). So, if the urbs are deallocated between those two calls due to the device deinitialization or suspend, it is possible that ath9k_hif_usb_rx_stream() is not called next time and the allocated remain_skb is leaked. Our local Syzkaller instance was able to trigger that. remain_skb makes sense when receiving two consecutive urbs which are logically linked together, i.e. a specific data field from the first skb indicates a cached skb to be allocated, memcpy'd with some data and subsequently processed in the next call to ath9k_hif_usb_rx_stream(). Urbs deallocation supposedly makes that link irrelevant so we need to free the cached skb in those cases. Fix the leak by introducing a function to explicitly free remain_skb (if it is not NULL) when the rx urbs have been deallocated. remain_skb is NULL when it has not been allocated at all (hif_dev struct is kzalloced) or when it has been processed in next call to ath9k_hif_usb_rx_stream().

2023-01-18wifi: ath12k: hal_rx: Use memset_startat() for clearing queue descriptorsThiraviyam Mariyappan
In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memset(), avoid intentionally writing across neighboring fields. Use memset_startat() so memset() doesn't get confused about writing beyond the destination member that is intended to be the starting point of zeroing through the end of the struct and fixes the below clang warning. Warning: include/linux/fortify-string.h:314:4: warning: call to '__write_overflow_field' declared with 'warning' attribute: detected write beyond size of field (1st parameter); maybe use struct_group()?

2023-01-18wifi: ath12k: wmi: delete PSOC_HOST_MAX_NUM_SSKalle Valo
Both PSOC_HOST_MAX_NUM_SS and WMI_MAX_NUM_SS are set to 8. The host assumes that the values are the same but there's no check for that, so things will break if either of the values change. It's simpler and safer to have just one define so delete PSOC_HOST_MAX_NUM_SS and use WMI_MAX_NUM_SS everywhere. No functional changes.

2023-01-18wifi: ath12k: hal: convert offset macros to functionsKalle Valo
After previous patch checkpatch was giving warnings: drivers/net/wireless/ath/ath12k/hal.h:158: Macro argument reuse 'ab' - possible side-effects? drivers/net/wireless/ath/ath12k/hal.h:160: Macro argument reuse 'ab' - possible side-effects? drivers/net/wireless/ath/ath12k/hal.h:162: Macro argument reuse 'ab' - possible side-effects? drivers/net/wireless/ath/ath12k/hal.h:164: Macro argument reuse 'ab' - possible side-effects? drivers/net/wireless/ath/ath12k/hal.h:173: Macro argument reuse 'ab' - possible side-effects? drivers/net/wireless/ath/ath12k/hal.h:175: Macro argument reuse 'ab' - possible side-effects? drivers/net/wireless/ath/ath12k/hal.h:177: Macro argument reuse 'ab' - possible side-effects? drivers/net/wireless/ath/ath12k/hal.h:179: Macro argument reuse 'ab' - possible side-effects? To fix those convert the macros into functions. As it was difficult to use struct ath12k_base within hal.h, core.h was already including hal.h so including back core.h would not work, move the functions also to hal.c. No functional changes.

2023-01-18wifi: ath12k: hal: add ab parameter to macros using itKalle Valo
It's considered evil if a macro is using a variable but not having the variable as a parameter. So add the ab parameter to macros using that. No functional changes.

crypto_alloc_shash() allocates resources, which should be released by crypto_free_shash(). When ath11k_peer_find() fails, there has memory leak. Add missing crypto_free_shash() to fix this.
