The new KPTI rewrite code uses __create_pgd_mapping() to create a temporary pagetable. This happens in atomic context, after secondary CPUs are brought up and the kernel has left the SYSTEM_BOOTING state. Hence we try to acquire a mutex in atomic context, which is generally unsound (though benign in this case as the mutex should be free and all other CPUs are quiescent). This patch avoids the issue by pulling the mutex out of alloc_init_pud() and calling it at a higher level in the pagetable manipulation code. This allows it to be used without locking where one CPU is known to be in exclusive control of the machine, even after having left the SYSTEM_BOOTING state.

2022-09-22net/smc: Unbind r/w buffer size from clcsock and make them tunableTony Lu
Currently, SMC uses smc->sk.sk_{rcv|snd}buf to create buffers for send buffer and RMB. And the values of buffer size are from tcp_{w|r}mem in clcsock. The buffer size from TCP socket doesn't fit SMC well. Generally, buffers are usually larger than TCP for SMC-R/-D to get higher performance, for they are different underlay devices and paths. So this patch unbinds buffer size from TCP, and introduces two sysctl knobs to tune them independently. Also, these knobs are per net namespace and work for containers.

2022-09-22net/smc: Introduce a specific sysctl for TEST_LINK timeWen Gu
SMC-R tests the viability of link by sending out TEST_LINK LLC messages over RoCE fabric when connections on link have been idle for a time longer than keepalive interval (testlink time). But using tcp_keepalive_time as testlink time maybe not quite suitable because it is default no less than two hours[1], which is too long for single link to find peer dead. The active host will still use peer-dead link (QP) sending messages, and can't find out until get IB_WC_RETRY_EXC_ERR error CQEs, which takes more time than TEST_LINK timeout (SMC_LLC_WAIT_TIME) normally. So this patch introduces a independent sysctl for SMC-R to set link keepalive time, in order to detect link down in time. The default value is 30 seconds.

2022-09-22wifi: ath11k: fix number of VHT beamformee spatial streamsJesus Fernandez Manzano
The number of spatial streams used when acting as a beamformee in VHT mode are reported by the firmware as 7 (8 sts - 1) both in IPQ6018 and IPQ8074 which respectively have 2 and 4 sts each. So the firmware should report 1 (2 - 1) and 3 (4 - 1). Fix this by checking that the number of VHT beamformee sts reported by the firmware is not greater than the number of receiving antennas - 1. The fix is based on the same approach used in this same function for sanitizing the number of sounding dimensions reported by the firmware. Without this change, acting as a beamformee in VHT mode is not working properly.

2022-09-22efi: libstub: check Shim mode using MokSBStateRTArd Biesheuvel
We currently check the MokSBState variable to decide whether we should treat UEFI secure boot as being disabled, even if the firmware thinks otherwise. This is used by shim to indicate that it is not checking signatures on boot images. In the kernel, we use this to relax lockdown policies. However, in cases where shim is not even being used, we don't want this variable to interfere with lockdown, given that the variable may be non-volatile and therefore persist across a reboot. This means setting it once will persistently disable lockdown checks on a given system. So switch to the mirrored version of this variable, called MokSBStateRT, which is supposed to be volatile, and this is something we can check.

2022-09-22efi: x86: Wipe setup_data on pure EFI bootArd Biesheuvel
When booting the x86 kernel via EFI using the LoadImage/StartImage boot services [as opposed to the deprecated EFI handover protocol], the setup header is taken from the image directly, and given that EFI's LoadImage has no Linux/x86 specific knowledge regarding struct bootparams or struct setup_header, any absolute addresses in the setup header must originate from the file and not from a prior loading stage. Since we cannot generally predict where LoadImage() decides to load an image (*), such absolute addresses must be treated as suspect: even if a prior boot stage intended to make them point somewhere inside the [signed] image, there is no way to validate that, and if they point at an arbitrary location in memory, the setup_data nodes will not be covered by any signatures or TPM measurements either, and could be made to contain an arbitrary sequence of SETUP_xxx nodes, which could interfere quite badly with the early x86 boot sequence. (*) Note that, while LoadImage() does take a buffer/size tuple in addition to a device path, which can be used to provide the image contents directly, it will re-allocate such images, as the memory footprint of an image is generally larger than the PE/COFF file representation.

2022-09-22wifi: ath11k: add get_txpower mac opsAditya Kumar Singh
Driver does not support get_txpower mac ops because of which cfg80211 returns vif->bss_conf.txpower to user space. bss_conf.txpower gets its value from ieee80211_channel->max_reg_power. However, the final txpower is dependent on few other parameters apart from max regulatory supported power. It is the firmware which knows about all these parameters and considers the minimum for each packet transmission. All ath11k firmware reports the final tx power in firmware pdev stats which falls under fw_stats. Add get_txpower mac ops to get the tx power from firmware leveraging fw_stats and return it accordingly.

2022-09-22ARM: 9224/1: Dump the stack traces based on the parameter 'regs' of show_regs()Zhen Lei
Function show_regs() is usually called in interrupt handler or exception handler, it prints the registers specified by the parameter 'regs', then dump the stack traces. Although not explicitly documented, dump the stack traces based on'regs' seems to make the most sense. Although dump_stack() can finally dump the desired content, because 'regs' are saved by the entry of current interrupt or exception. In the following example we can see: 1) The backtrace of interrupt or exception handler is not expected, it causes confusion. 2) Something is printed repeatedly. The line with the kernel version "CPU: 0 PID: 70 Comm: test0 Not tainted 5.19.0+ #8", the registers saved in "Exception stack" which 'regs' actually point to.

2022-09-22wifi: ath10k: reset pointer after memory free to avoid potential use-after-freeWen Gong
When running suspend test, kernel crash happened in ath10k, and it is fixed by commit b72a4aff947b ("ath10k: skip ath10k_halt during suspend for driver state RESTARTING"). Currently the crash is fixed, but as a common code style, it is better to set the pointer to NULL after memory is free. This is to address the code style and it will avoid potential bug of use-after-free.

It has a fail log which is ath11k_dbg in ath11k_dp_rx_process_mon_status(), as below, it will not print when debug_mask is not set ATH11K_DBG_DATA. ath11k_dbg(ab, ATH11K_DBG_DATA, "failed to find the peer with peer_id %d\n", ppdu_info.peer_id); When run scan with station disconnected, the peer_id is 0 for case HAL_RX_MPDU_START in ath11k_hal_rx_parse_mon_status_tlv() which called from ath11k_dp_rx_process_mon_status(), and the peer_id of ppdu_info is reset to 0 in the while loop, so it does not match condition of the check "if (ppdu_info->peer_id == HAL_INVALID_PEERID" in the loop, and then the log "failed to find the peer with peer_id 0" print after the check in the loop, it is below call stack when debug_mask is set ATH11K_DBG_DATA. The reason is this commit 01d2f285e3e5 ("ath11k: decode HE status tlv") add "memset(ppdu_info, 0, sizeof(struct hal_rx_mon_ppdu_info))" in ath11k_dp_rx_process_mon_status(), but the commit does not initialize the peer_id to HAL_INVALID_PEERID, then lead the check mis-match.

Currently commit 1f682dc9fb37 ("ath11k: reduce the wait time of 11d scan and hw scan while add interface") introduced a wait_for_completion_timeout operation for ar->scan.completed, another one is existed in ath11k_scan_stop(), then ath11k has two places to wait for the ar->scan.completed and they run in different thread, thus it is possible to happend that the two thread both enter wait status. To handle this scenario, ath11k should change the complete() to complete_all() for the ar->scan.completed. This also work well when it is only one thread wait for ar->scan.completed.

[ 135.389205] usb 1-1: == mwifiex dump information to /sys/class/devcoredump end This patch uses delayed work to replace timer and moves the operations that may sleep into a delayed work in order to mitigate bugs, it was tested on Marvell 88W8801 chip whose port is usb and the firmware is usb8801_uapsta.bin. The following is the result after using delayed work to replace timer.
