2023-04-17arm64/cpufeature: Pull out helper for CPUID register definitionsMark Brown
We use the same structure to match hwcaps and CPU features so we can use the same helper to generate the fields required. Pull the portion of the current hwcaps helper that initialises the fields out into a separate define placed earlier in the file so we can use it for cpufeatures. No functional change.

2023-04-17ACPI: AGDI: Improve error reporting for problems during .remove()Uwe Kleine-König
Returning an error value in a platform driver's remove callback results in a generic error message being emitted by the driver core, but otherwise it doesn't make a difference. The device goes away anyhow. So instead of triggering the generic platform error message, emit a more helpful message if a problem occurs and return 0 to suppress the generic message. This patch is a preparation for making platform remove callbacks return void.

2023-04-17wifi: ath9k: fix per-packet TX-power cap for TPCJonas Jelonek
Fix incorrect usage of plain rate_idx as index into the max (power) per rate lookup table. For transmit power control (TPC), the ath9k driver maintains internal tables (in struct ath_hw) to store the max allowed power level per rate. They are used to limit a given TX-power according to regulatory and user limits in the TX-path per packet. The tables are filled in a predefined order, starting with values for CCK + OFDM rates and followed by the values for MCS rates. Thus, the maximum power levels for MCS do not start at index 0 in the table but are shifted by a fixed value. The TX-power limiting in ath_get_rate_txpower currently does not apply this shift, thus retrieves the incorrect maximum power level for a given rate. In particular for MCS rates, the maximum power levels for CCK/OFDM rates were used, e.g. maximum power for OFDM 0 was used for MCS 0. If STBC is used, the power is mostly limited to 0 because the STBC table is zeroed for legacy CCK/OFDM rates. Encountered this during testing of our work-in-progress TPC per packet for ath9k. This only has an effect when TPC is enabled in ath9k (tpc_enabled in struct ath_hw) which defaults to false. In this case it has a significant impact on the used TX-power, throughput + RSSI. Otherwise the affected code is just skipped and TX-power is limited with the hardware registers only. This patch fixes this table lookup. Tested on OpenWrt (kernel 5.15.98, but backported ath9k driver) with small desk setup using ath9k chips AR9280 and AR9580. Cap of TX-power is working properly for all rates now, throughput and RSSI as expected, equal to as if TPC was disabled. Compile-tested with latest 6.3 kernel + allyesconfig.

2023-04-17wifi: ath11k: Ignore frags from uninitialized peer in dp.Harshitha Prem
When max virtual ap interfaces are configured in all the bands with ACS and hostapd restart is done every 60s, a crash is observed at random times. In this certain scenario, a fragmented packet is received for self peer, for which rx_tid and rx_frags are not initialized in datapath. While handling this fragment, crash is observed as the rx_frag list is uninitialised and when we walk in ath11k_dp_rx_h_sort_frags, skb null leads to exception. To address this, before processing received fragments we check dp_setup_done flag is set to ensure that peer has completed its dp peer setup for fragment queue, else ignore processing the fragments.

On the X380 Yoga, the `ECRD` and `ECWR` ACPI objects cannot be used for accessing the Embedded Controller: instead of a method that reads from the EC's memory, `ECRD` is the name of a location in high memory. This meant that trying to call them would fail with the following message: ACPI: \_SB.PCI0.LPCB.EC.ECRD: 1 arguments were passed to a non-method ACPI object (RegionField) With this commit, it is now possible to access the EC and read temperature and fan speed information. Note that while writes to the HFSP register do go through (as indicated by subsequent reads showing the new value), the fan does not actually change its speed.

2023-04-17net/sched: clear actions pointer in miss cookie init failPedro Tammela
Palash reports a UAF when using a modified version of syzkaller[1]. When 'tcf_exts_miss_cookie_base_alloc()' fails in 'tcf_exts_init_ex()' a call to 'tcf_exts_destroy()' is made to free up the tcf_exts resources. In flower, a call to '__fl_put()' when 'tcf_exts_init_ex()' fails is made; Then calling 'tcf_exts_destroy()', which triggers an UAF since the already freed tcf_exts action pointer is lingering in the struct. Before the offending patch, this was not an issue since there was no case where the tcf_exts action pointer could linger. Therefore, restore the old semantic by clearing the action pointer in case of a failure to initialize the miss_cookie.

2023-04-17net: lan966x: Fix lan966x_ifh_getHoratiu Vultur
From time to time, it was observed that the nanosecond part of the received timestamp, which is extracted from the IFH, it was actually bigger than 1 second. So then when actually calculating the full received timestamp, based on the nanosecond part from IFH and the second part which is read from HW, it was actually wrong. The issue seems to be inside the function lan966x_ifh_get, which extracts information from an IFH(which is an byte array) and returns the value in a u64. When extracting the timestamp value from the IFH, which starts at bit 192 and have the size of 32 bits, then if the most significant bit was set in the timestamp, then this bit was extended then the return value became 0xffffffff... . And the reason of this is because constants without any postfix are treated as signed longs and that is the reason why '1 << 31' becomes 0xffffffff80000000. This is fixed by adding the postfix 'ULL' to 1. Fixes: fd7627833ddf ("net: lan966x: Stop using packing library") Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: David S.
