2024-08-05can: flexcan: add wakeup support for imx95Haibo Chen
iMX95 defines a bit in GPR that sets/unsets the IPG_STOP signal to the FlexCAN module, controlling its entry into STOP mode. Wakeup should work even if FlexCAN is in STOP mode. Due to iMX95 architecture design, the A-Core cannot access GPR; only the system manager (SM) can configure GPR. To support the wakeup feature, follow these steps: - For suspend: 1) During Linux suspend, when CAN suspends, do nothing for GPR and keep CAN-related clocks on. 2) In ATF, check whether CAN needs to support wakeup; if yes, send a request to SM through the SCMI protocol. 3) In SM, configure the GPR and unset IPG_STOP. 4) A-Core suspends. - For wakeup and resume: 1) A-Core wakeup event arrives. 2) In SM, deassert IPG_STOP. 3) Linux resumes. Add a new fsl_imx95_devtype_data and FLEXCAN_QUIRK_SETUP_STOP_MODE_SCMI to reflect this.

2024-08-05drm/mediatek: Set sensible cursor width/height values to fix crashAngeloGioacchino Del Regno
Hardware-speaking, there is no feature-reduced cursor specific plane, so this driver reserves the last all Overlay plane as a Cursor plane, but sets the maximum cursor width/height to the maximum value that the full overlay plane can use. While this could be ok, it raises issues with common userspace using libdrm (especially Mutter, but other compositors too) which will crash upon performing allocations and/or using said cursor plane. Reduce the maximum width/height for the cursor to 512x512 pixels, value taken from IGT's maximum cursor size test, which succeeds.

2024-08-05wifi: ath12k: use 128 bytes aligned iova in transmit path for WCN7850Baochen Qiang
In transmit path, it is likely that the iova is not aligned to PCIe TLP max payload size, which is 128 for WCN7850. Normally in such cases hardware is expected to split the packet into several parts in a manner such that they, other than the first one, have aligned iova. However due to hardware limitations, WCN7850 does not behave like that properly with some specific unaligned iova in transmit path. This easily results in target hang in a KPI transmit test: packet send/receive failure, WMI command send timeout etc. Also fatal error seen in PCIe level: ... Capabilities: ... ... DevSta: ... FatalErr+ ... ... ... Work around this by manually moving/reallocating payload buffer such that we can map it to a 128 bytes aligned iova. The moving requires sufficient head room or tail room in skb: for the former we can do ourselves a favor by asking some extra bytes when registering with mac80211, while for the latter we can do nothing. Moving/reallocating buffer consumes additional CPU cycles, but the good news is that an aligned iova increases PCIe efficiency. In my tests on some X86 platforms the KPI results are almost consistent. Since this is seen only with WCN7850, add a new hardware parameter to differentiate from others.

2024-08-04Input: uinput - reject requests with unreasonable number of slotsDmitry Torokhov
From: Dmitry Torokhov <dmitry.torokhov@gmail.com> When exercising uinput interface syzkaller may try setting up device with a really large number of slots, which causes memory allocation failure in input_mt_init_slots(). While this allocation failure is handled properly and request is rejected, it results in syzkaller reports. Additionally, such request may put undue burden on the system which will try to free a lot of memory for a bogus request. Fix it by limiting allowed number of slots to 100. This can easily be extended if we see devices that can track more than 100 contacts.

2024-08-04i2c: smbus: Send alert notifications to all devices if source not foundGuenter Roeck
If a SMBus alert is received and the originating device is not found, the reason may be that the address reported on the SMBus alert address is corrupted, for example because multiple devices asserted alert and do not correctly implement SMBus arbitration. If this happens, call alert handlers on all devices connected to the given I2C bus, in the hope that this cleans up the situation. This change reliably fixed the problem on a system with multiple devices on a single bus. Example log where the device on address 0x18 (ADM1021) and on address 0x4c (ADT7461A) both had the alert line asserted: smbus_alert 3-000c: SMBALERT# from dev 0x0c, flag 0 smbus_alert 3-000c: no driver alert()! smbus_alert 3-000c: SMBALERT# from dev 0x0c, flag 0 smbus_alert 3-000c: no driver alert()! lm90 3-0018: temp1 out of range, please check! lm90 3-0018: Disabling ALERT# lm90 3-0029: Everything OK lm90 3-002a: Everything OK lm90 3-004c: temp1 out of range, please check! lm90 3-004c: temp2 out of range, please check! lm90 3-004c: Disabling ALERT# Fixes: b5527a7766f0 ("i2c: Add SMBus alert support") Signed-off-by: Guenter Roeck <linux@roeck-us.net> [wsa: fixed a typo in the commit message] Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com>

2024-08-04wifi: brcmfmac: introducing fwil query functionsArend van Spriel
When the firmware interface layer was refactored it provided various "get" and "set" functions. For the "get" in some cases a parameter needed to be passed down to firmware as a key indicating what to "get" turning the output parameter of the "get" function into an input parameter as well. To accommodate this the "get" function blindly copies the parameter which in some places resulted in an uninitialized warnings from the compiler. These have been fixed by initializing the input parameter in the past. Recently another batch of similar fixes were submitted to address clang static checker warnings [1]. Proposing another solution by introducing a "query" variant which is used when the (input) parameter is needed by firmware. The "get" variant will only fill the (output) parameter with the result received from firmware taking care of proper endianess conversion.

2024-08-04wifi: brcmfmac: fwsignal: Use struct_size() to simplify brcmf_fws_rxreorder()Christophe JAILLET
In the "struct brcmf_ampdu_rx_reorder", change the 'pktslots' field into flexible array. It saves the size of a pointer when the memory is allocated and avoids an indirection when the array is used. It also removes the usage of a pointer arithmetic and saves a few lines of code. Finally, struct_size() can be used. It is not a must have here, because it is easy to see that buf_size can not overflow, but still, it is a good practice.

2024-08-03iio: adc: ad7124: fix config comparisonDumitru Ceclan
The ad7124_find_similar_live_cfg() computes the compare size by substracting the address of the cfg struct from the address of the live field. Because the live field is the first field in the struct, the result is 0. Also, the memcmp() call is made from the start of the cfg struct, which includes the live and cfg_slot fields, which are not relevant for the comparison. Fix by grouping the relevant fields with struct_group() and use the size of the group to compute the compare size; make the memcmp() call from the address of the group.

The ad7124_soft_reset() function has the assumption that the chip will assert the "power-on reset" bit in the STATUS register after a software reset without any delay. The POR bit =0 is used to check if the chip initialization is done. A chip ID mismatch probe error appears intermittently when the probe continues too soon and the ID register does not contain the expected value. Fix by adding a 200us delay after the software reset command is issued.

2024-08-02scsi: sd: Keep the discard mode stableLi Feng
There is a scenario where a large number of discard commands are issued when the iscsi initiator connects to the target and then performs a session rescan operation. There is a time window, most of the commands are in UNMAP mode, and some discard commands become WRITE SAME with UNMAP. The discard mode has been negotiated during the SCSI probe. If the mode is temporarily changed from UNMAP to WRITE SAME with UNMAP, an I/O ERROR may occur because the target may not implement WRITE SAME with UNMAP. Keep the discard mode stable to fix this issue.

According to the datasheet, the VSC73xx family's maximum internal MDIO bus speed is 20 MHz. It also allows disabling the preamble. This commit sets the MDIO clock prescaler to the minimum value and disables the preamble to speed up MDIO operations. It doesn't affect the external bus because it's configured in a different subblock.

2024-08-02gve: Fix use of netif_carrier_ok()Praveen Kaligineedi
GVE driver wrongly relies on netif_carrier_ok() to check the interface administrative state when resources are being allocated/deallocated for queue(s). netif_carrier_ok() needs to be replaced with netif_running() for all such cases. Administrative state is the result of "ip link set dev <dev> up/down". It reflects whether the administrator wants to use the device for traffic and the corresponding resources have been allocated.
