2023-07-23platform/x86: wmi: Break possible infinite loop when parsing GUIDAndy Shevchenko1-10/+12
[ Upstream commit 028e6e204ace1f080cfeacd72c50397eb8ae8883 ] The while-loop may break on one of the two conditions, either ID string is empty or GUID matches. The second one, may never be reached if the parsed string is not correct GUID. In such a case the loop will never advance to check the next ID. Break possible infinite loop by factoring out guid_parse_and_compare() helper which may be moved to the generic header for everyone later on and preventing from similar mistake in the future. Interestingly that firstly it appeared when WMI was turned into a bus driver, but later when duplicated GUIDs were checked, the while-loop has been replaced by for-loop and hence no mistake made again.

2023-07-23net: bgmac: postpone turning IRQs off to avoid SoC hangsRafał Miłecki1-2/+2
[ Upstream commit e7731194fdf085f46d58b1adccfddbd0dfee4873 ] Turning IRQs off is done by accessing Ethernet controller registers. That can't be done until device's clock is enabled. It results in a SoC hang otherwise. This bug remained unnoticed for years as most bootloaders keep all Ethernet interfaces turned on. It seems to only affect a niche SoC family BCM47189. It has two Ethernet controllers but CFE bootloader uses only the first one.

2023-07-23igc: Handle PPS start time programming for past time valuesAravindhan Gunasekaran1-3/+22
[ Upstream commit 84a192e46106355de1a314d709e657231d4b1026 ] I225/6 hardware can be programmed to start PPS output once the time in Target Time registers is reached. The time programmed in these registers should always be into future. Only then PPS output is triggered when SYSTIM register reaches the programmed value. There are two modes in i225/6 hardware to program PPS, pulse and clock mode. There were issues reported where PPS is not generated when start time is in past. Example 1, "echo 0 0 0 2 0 > /sys/class/ptp/ptp0/period" In the current implementation, a value of '0' is programmed into Target time registers and PPS output is in pulse mode. Eventually an interrupt which is triggered upon SYSTIM register reaching Target time is not fired. Thus no PPS output is generated. Example 2, "echo 0 0 0 1 0 > /sys/class/ptp/ptp0/period" Above case, a value of '0' is programmed into Target time registers and PPS output is in clock mode. Here, HW tries to catch-up the current time by incrementing Target Time register. This catch-up time seem to vary according to programmed PPS period time as per the HW design. In my experiments, the delay ranged between few tens of seconds to few minutes. The PPS output is only generated after the Target time register reaches current time. In my experiments, I also observed PPS stopped working with below test and could not recover until module is removed and loaded again. 1) echo 0 <future time> 0 1 0 > /sys/class/ptp/ptp1/period 2) echo 0 0 0 1 0 > /sys/class/ptp/ptp1/period 3) echo 0 0 0 1 0 > /sys/class/ptp/ptp1/period After this PPS did not work even if i re-program with proper values. I could only get this back working by reloading the driver. This patch takes care of calculating and programming appropriate future time value into Target Time registers.

Furthermore, old SKUs like as I225 will call the reset_adapter to reset the controller during TSN mode Gate Control List (GCL) setting. This will add more time to the configuration of the real-time use case. It doesn't mentioned about this delay in the Software User Manual. It might have been ported from legacy code I210 in the past.

2023-07-23drm/bridge: ti-sn65dsi86: Fix auxiliary bus lifetimeDouglas Anderson1-13/+22
[ Upstream commit 7aa83fbd712a6f08ffa67890061f26d140c2a84f ] Memory for the "struct device" for any given device isn't supposed to be released until the device's release() is called. This is important because someone might be holding a kobject reference to the "struct device" and might try to access one of its members even after any other cleanup/uninitialization has happened. Code analysis of ti-sn65dsi86 shows that this isn't quite right. When the code was written, it was believed that we could rely on the fact that the child devices would all be freed before the parent devices and thus we didn't need to worry about a release() function. While I still believe that the parent's "struct device" is guaranteed to outlive the child's "struct device" (because the child holds a kobject reference to the parent), the parent's "devm" allocated memory is a different story. That appears to be freed much earlier. Let's make this better for ti-sn65dsi86 by allocating each auxiliary with kzalloc and then free that memory in the release().

2023-07-19wireguard: netlink: send staged packets when setting initial private keyJason A. Donenfeld1-5/+9
commit f58d0a9b4c6a7a5199c3af967e43cc8b654604d4 upstream. Packets bound for peers can queue up prior to the device private key being set. For example, if persistent keepalive is set, a packet is queued up to be sent as soon as the device comes up. However, if the private key hasn't been set yet, the handshake message never sends, and no timer is armed to retry, since that would be pointless. But, if a user later sets a private key, the expectation is that those queued packets, such as a persistent keepalive, are actually sent. So adjust the configuration logic to account for this edge case, and add a test case to make sure this works. Maxim noticed this with a wg-quick(8) config to the tune of: [Interface] PostUp = wg set %i private-key somefile [Peer] PublicKey = ... Endpoint = ... PersistentKeepalive = 25 Here, the private key gets set after the device comes up using a PostUp script, triggering the bug.

2023-07-19mtd: parsers: refer to ARCH_BCMBCA instead of ARCH_BCM4908Lukas Bulwahn1-1/+1
commit 085679b15b5af65f9610f619afde41da0f966194 upstream. Commit dd5c672d7ca9 ("arm64: bcmbca: Merge ARCH_BCM4908 to ARCH_BCMBCA") removes config ARCH_BCM4908 as config ARCH_BCMBCA has the same intent. Probably due to concurrent development, commit 002181f5b150 ("mtd: parsers: add Broadcom's U-Boot parser") introduces 'Broadcom's U-Boot partition parser' that depends on ARCH_BCM4908, but this use was not visible during the config refactoring from the commit above.

2023-07-19drm/i915/tc: Fix system resume MST mode restore for DP-alt sinksImre Deak2-3/+47
commit 06f66261a1567d66b9d35c87393b6edfbea4c8f8 upstream. At least restoring the MST topology during system resume needs to use AUX before the display HW readout->sanitization sequence is complete, but on TC ports the PHY may be in the wrong mode for this, resulting in the AUX transfers to fail. The initial TC port mode is kept fixed as BIOS left it for the above HW readout sequence (to prevent changing the mode on an enabled port). If the port is disabled this initial mode is TBT - as in any case the PHY ownership is not held - even if a DP-alt sink is connected. Thus, the AUX transfers during this time will use TBT mode instead of the expected DP-alt mode and so time out. Fix the above by connecting the PHY during port initialization if the port is disabled, which will switch to the expected mode (DP-alt in the above case). As the encoder/pipe HW state isn't read-out yet at this point, check if the port is enabled based on the DDI_BUF enabled flag. Save the read-out initial mode, so intel_tc_port_sanitize_mode() can check this wrt. the read-out encoder HW state.

2023-07-19drm/i915/tc: Fix TC port link ref init for DP MST during HW readoutImre Deak1-9/+11
commit 67165722c27cc46de112a4e10b450170c8980a6f upstream. An enabled TC MST port holds one TC port link reference, regardless of the number of enabled streams on it, but the TC port HW readout takes one reference for each active MST stream. Fix the HW readout, taking only one reference for MST ports. This didn't cause an actual problem, since the encoder HW readout doesn't yet support reading out the MST HW state.

2023-07-19drm/i915: Fix TypeC mode initialization during system resumeImre Deak3-17/+60
commit a82796a2e332d108b2d3aff38509caad370f69b5 upstream. During system resume DP MST requires AUX to be working already before the HW state readout of the given encoder. Since AUX requires the encoder/PHY TypeC mode to be initialized, which atm only happens during HW state readout, these AUX transfers can change the TypeC mode incorrectly (disconnecting the PHY for an enabled encoder) and trigger the state check WARNs in intel_tc_port_sanitize(). Fix this by initializing the TypeC mode earlier both during driver loading and system resume and making sure that the mode can't change until the encoder's state is read out. While at it add the missing DocBook comments and rename intel_tc_port_sanitize()->intel_tc_port_sanitize_mode() for consistency.

commit f050e56de80591fee55bedbdf5b6b998c740cd0c upstream. The driver's probe() first registers regulators in a loop and then in a second loop passes them as irq data to the interrupt handlers. However the function to get the regulator for given name tps65219_get_rdev_by_name() was a no-op due to argument passed by value, not pointer, thus the second loop assigned always same value - from previous loop.

commit a7fbfd44c0204f0629288edfd0d77829edb4a2f8 upstream. power_supply_is_system_supplied() checks whether any power supplies are present that aren't batteries to decide whether the system is running on DC or AC. Downstream drivers use this to make performance decisions. Navi dGPUs include an UCSI function that has been exported since commit 17631e8ca2d3 ("i2c: designware: Add driver support for AMD NAVI GPU"). This UCSI function registers a power supply since commit 992a60ed0d5e ("usb: typec: ucsi: register with power_supply class") but this is not a system power supply. As the power supply for a dGPU is only for powering devices connected to dGPU, create a device property to indicate that the UCSI endpoint is only for the scope of `POWER_SUPPLY_SCOPE_DEVICE`.

commit 20dbd07ef0a8bc29eb03d6a95258ac8934cbe52d upstream. Bayhub SD host has hardware limitation: 1.The upper 32bit address is inhibited to be written at SD Host Register [03E][13]=0 (32bits addressing) mode, is admitted to be written only at SD Host Register [03E][13]=1 (64bits addressing) mode. 2.Because of above item#1, need to configure SD Host Register [03E][13] to 1(64bits addressing mode) before set 64bit ADMA system address's higher 32bits SD Host Register [05F~05C] if 64 bits addressing mode is used. The hardware limitation is reasonable for below reasons: 1.Normal flow should set DMA working mode first, then do DMA-transfer-related configuration, such as system address. 2.The hardware limitation may avoid the software to configure wrong higher 32bit address at 32bits addressing mode although it is redundant. The change that set 32bits/64bits addressing mode before set ADMA address, has no side-effect to other host IPs for below reason: The setting order is reasonable and standard: DMA Mode setting first and then DMA address setting. It meets all DMA setting sequence.
