Normal LPS is decomposed into pre- and post- parts, so we can issue H2C with TDMA parameters in the "critical section" that dirver can't change LPS state at the moment. Signed-off-by:

btcoex uses dm's counters to check the environment is noisy or not. If it is clean, btcoex set more time slots to WiFi so that it can transmit as soon as possible. That will save time, and BT will have more time slots after WiFi traffic is complete. Signed-off-by:

The use of stack Variable Length Arrays needs to be avoided, as they can be a vector for stack exhaustion, which can be both a runtime bug (kernel Oops) or a security flaw (overwriting memory beyond the stack). Also, in general, as code evolves it is easy to lose track of how big a VLA can get. Thus, we can end up having runtime failures that are hard to debug. As part of the directive[1] to remove all VLAs from the kernel, and build with -Wvla. Currently rsi code uses a VLA based on a function argument to `rsi_sdio_load_data_master_write()`. The function call chain is Both these functions rsi_sdio_reinit_device() rsi_probe() start the call chain: rsi_hal_device_init() rsi_load_fw() auto_fw_upgrade() ping_pong_write() rsi_sdio_load_data_master_write() [Without familiarity with the code] it appears that none of the 4 locks mutex rx_mutex tx_mutex tx_bus_mutex are held when `rsi_sdio_load_data_master_write()` is called. It is therefore safe to use kmalloc with GFP_KERNEL. We can avoid using the VLA by using `kmalloc()` and free'ing the memory on all exit paths. Change buffer from 'u8 array' to 'u8 *'. Call `kmalloc()` to allocate memory for the buffer. Using goto statement to call `kfree()` on all return paths. It can be expected that this patch will result in a small increase in overhead due to the use of `kmalloc()` however this code is only called on initialization (and re-initialization) so this overhead should not degrade performance.

The linkage between the bluetooth driver and the wireless driver is not defined properly, leading to build problems such as: warning: (BT_HCIRSI) selects RSI_COEX which has unmet direct dependencies (NETDEVICES && WLAN && WLAN_VENDOR_RSI && BT_HCIRSI && RSI_91X) drivers/net/wireless/rsi/rsi_91x_main.o: In function `rsi_read_pkt': (.text+0x205): undefined reference to `rsi_bt_ops' As the dependency is actually the reverse (RSI_91X uses the BT_RSI driver, not the other way round), this changes the dependency to match, and enables the bluetooth driver from the RSI_COEX symbol.

When attempt to run worker (ath10k_sta_rc_update_wk) after the station object (ieee80211_sta) delete will trigger the kernel panic. This problem arise in AP + Mesh configuration, Where the current node AP VAP and neighbor node mesh VAP MAC address are same. When the current mesh node try to establish the mesh link with neighbor node, driver peer creation for the neighbor mesh node fails due to duplication MAC address. Already the AP VAP created with same MAC address. It is caused by the following scenario steps. Steps: 1. In above condition, ath10k driver sta_state callback (ath10k_sta_state) fails to do the state change for a station from IEEE80211_STA_NOTEXIST to IEEE80211_STA_NONE due to peer creation fails. Sta_state callback is called from ieee80211_add_station() to handle the new station (neighbor mesh node) request from the wpa_supplicant. 2. Concurrently ath10k receive the sta_rc_update callback notification from the mesh_neighbour_update() to handle the beacon frames of the above neighbor mesh node. since its atomic callback, ath10k driver queue the work (ath10k_sta_rc_update_wk) to handle rc update. 3. Due to driver sta_state callback fails (step 1), mac80211 free the station object. 4. When the worker (ath10k_sta_rc_update_wk) scheduled to run, it will access the station object which is already deleted. so it will trigger kernel panic. Added the peer exist check in sta_rc_update callback before queue the work.

The skb may be freed in tx completion context before trace_ath10k_wmi_cmd is called. This can be easily captured when KASAN(Kernel Address Sanitizer) is enabled. The fix is to move trace_ath10k_wmi_cmd before the send operation. As the ret has no meaning in trace_ath10k_wmi_cmd then, so remove this parameter too. Signed-off-by:

Added per tid sta counters for the following - Total number MSDUs received from firmware - Number of MSDUs received with errors like decryption, crc, mic ,etc. - Number of MSDUs dropped in the driver - A-MPDU/A-MSDU subframe stats - Number of MSDUS passed to mac80211 All stats other than A-MPDU stats are only for received data frames. A-MPDU stats might have stats for management frames when monitor interface is active where management frames are notified both in wmi and HTT interfaces. These per tid stats can be enabled with tid bitmask through a debugfs like below echo <tid_bitmask> > /sys/kernel/debug/ieee80211/phyX/ath10k/sta_tid_stats_mask tid 16 (tid_bitmask 0x10000) is used for non-qos data/management frames The stats are read from /sys/kernel/debug/ieee80211/phyX/netdev\:wlanX/stations/<sta_mac>/dump_tid_stats Sample output: To enable rx stats for tid 0, 5 and 6, echo 0x00000061 > /sys/kernel/debug/ieee80211/phy0/ath10k/sta_tid_stats_mask cat /sys/kernel/debug/ieee80211/phy0/netdev\:wlan15/stations/8c\:fd\:f0\:0a\:8e\:df/dump_tid_stats Driver Rx pkt stats per tid, ([tid] count) ------------------------------------------ MSDUs from FW [00] 2567 [05] 3178 [06] 1089 MSDUs unchained [00] 0 [05] 0 [06] 0 MSDUs locally dropped:chained [00] 0 [05] 0 [06] 0 MSDUs locally dropped:filtered [00] 0 [05] 0 [06] 0 MSDUs queued for mac80211 [00] 2567 [05] 3178 [06] 1089 MSDUs with error:fcs_err [00] 0 [05] 0 [06] 2 MSDUs with error:tkip_err [00] 0 [05] 0 [06] 0 MSDUs with error:crypt_err [00] 0 [05] 0 [06] 0 MSDUs with error:peer_idx_inval [00] 0 [05] 0 [06] 0 A-MPDU num subframes upto 10 [00] 2567 [05] 3178 [06] 1087 A-MPDU num subframes 11-20 [00] 0 [05] 0 [06] 0 A-MPDU num subframes 21-30 [00] 0 [05] 0 [06] 0 A-MPDU num subframes 31-40 [00] 0 [05] 0 [06] 0 A-MPDU num subframes 41-50 [00] 0 [05] 0 [06] 0 A-MPDU num subframes 51-60 [00] 0 [05] 0 [06] 0 A-MPDU num subframes >60 [00] 0 [05] 0 [06] 0 A-MSDU num subframes 1 [00] 2567 [05] 3178 [06] 1089 A-MSDU num subframes 2 [00] 0 [05] 0 [06] 0 A-MSDU num subframes 3 [00] 0 [05] 0 [06] 0 A-MSDU num subframes 4 [00] 0 [05] 0 [06] 0 A-MSDU num subframes >4 [00] 0 [05] 0 [06] 0 Signed-off-by:Vasanthakumar Thiagarajan <vthiagar@codeaurora.org> Signed-off-by:

When NetworkManager is enabled, there are chances that interface up is called even before probe completes.

Unlike the moder modern SYSTEMPORT hardware, we do not have a configurable TDMA timeout, which limits us to implement adaptive RX interrupt coalescing only. We have each of our RX rings implement a bcmgenet_net_dim structure which holds an interrupt counter, number of packets, bytes, and a container for a net_dim instance. Signed-off-by:

Andrew Lunn says: ==================== Fixes to allow mv88e6xxx module to be reloaded As reported by Uwe Kleine-König, the interrupt trigger is first configured by DT and then reconfigured to edge. This results in a failure on EPROBE_DEFER, or if the module is unloaded and reloaded. A second crash happens on module reload due to a missing call to the common IRQ free code when using polled interrupts. With these fixes in place, it becomes possible to load and unload the kernel modules a few times without it crashing. v2: Fix the ü in Künig a couple of times v3: But the ü should be an ö! ==================== Signed-off-by: -
