2023-11-22nvme: target: fix Kconfig select statementsArnd Bergmann
When the NVME target code is built-in but its TCP frontend is a loadable module, enabling keyring support causes a link failure: x86_64-linux-ld: vmlinux.o: in function `nvmet_ports_make': configfs.c:(.text+0x100a211): undefined reference to `nvme_keyring_id' The problem is that CONFIG_NVME_TARGET_TCP_TLS is a 'bool' symbol that depends on the tristate CONFIG_NVME_TARGET_TCP, so any 'select' from it inherits the state of the tristate symbol rather than the intended CONFIG_NVME_TARGET one that contains the actual call. The same thing is true for CONFIG_KEYS, which itself is required for NVME_KEYRING.

2023-11-22nvme: target: fix nvme_keyring_id() referencesArnd Bergmann
In configurations without CONFIG_NVME_TARGET_TCP_TLS, the keyring code might not be available, or using it will result in a runtime failure: x86_64-linux-ld: vmlinux.o: in function `nvmet_ports_make': configfs.c:(.text+0x100a211): undefined reference to `nvme_keyring_id' Add a check to ensure we only check the keyring if there is a chance of it being used, which avoids both the runtime and link-time problems.

2023-11-22cxl/hdm: Fix a benign lockdep splatDave Jiang
The new helper "cxl_num_decoders_committed()" added a lockdep assertion to validate that port->commit_end is protected against modification. That assertion fires in init_hdm_decoder() where it is initializing port->commit_end. Given that it is both accessing and writing that property it obstensibly needs the lock. In practice, CXL decoder commit rules (must commit in order) and the in-order discovery of device decoders makes the manipulation of ->commit_end in init_hdm_decoder() safe. However, rather than rely on the subtle rules of CXL hardware, just make the implementation obviously correct from a software perspective. The Fixes: tag is only for cleaning up a lockdep splat, there is no functional issue addressed by this fix.

Stopping keep-alive not only stops the keep-alive workqueue, but also needs to be synchronized with I/O termination as we must not send a keep-alive command after all I/O had been terminated.

2023-11-22Revert "net: r8169: Disable multicast filter for RTL8168H and RTL8107E"Heiner Kallweit
This reverts commit efa5f1311c4998e9e6317c52bc5ee93b3a0f36df. I couldn't reproduce the reported issue. What I did, based on a pcap packet log provided by the reporter: - Used same chip version (RTL8168h) - Set MAC address to the one used on the reporters system - Replayed the EAPOL unicast packet that, according to the reporter, was filtered out by the mc filter. The packet was properly received. Therefore the root cause of the reported issue seems to be somewhere else. Disabling mc filtering completely for the most common chip version is a quite big hammer. Therefore revert the change and wait for further analysis results from the reporter. Cc: stable@vger.kernel.org Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S.

2023-11-22leds: class: Don't expose color sysfs entryTakashi Iwai
The commit c7d80059b086 ("leds: class: Store the color index in struct led_classdev") introduced a new sysfs entry "color" that is commonly created for the led classdev. Unfortunately, this conflicts with the "color" sysfs entry of already existing drivers such as Logitech HID or System76 ACPI drivers. The driver probe fails due to the conflict, hence it leads to a severe regression with the missing keyboard, for example. This patch reverts partially the change in the commit above for removing the led class color sysfs entries again for addressing the regressions. The newly introduced led_classdev.color field is kept as it's already used by other driver.

2023-11-22RDMA/rtrs-srv: Destroy path files after making sure no IOs in-flightMd Haris Iqbal
Destroying path files may lead to the freeing of rdma_stats. This creates the following race. An IO is in-flight, or has just passed the session state check in process_read/process_write. The close_work gets triggered and the function rtrs_srv_close_work() starts and does destroy path which frees the rdma_stats. After this the function process_read/process_write resumes and tries to update the stats through the function rtrs_srv_update_rdma_stats This commit solves the problem by moving the destroy path function to a later point. This point makes sure any inflights are completed. This is done by qp drain, and waiting for all in-flights through ops_id.

2023-11-21net: usb: ax88179_178a: fix failed operations during ax88179_resetJose Ignacio Tornos Martinez
Using generic ASIX Electronics Corp. AX88179 Gigabit Ethernet device, the following test cycle has been implemented: - power on - check logs - shutdown - after detecting the system shutdown, disconnect power - after approximately 60 seconds of sleep, power is restored Running some cycles, sometimes error logs like this appear: kernel: ax88179_178a 2-9:1.0 (unnamed net_device) (uninitialized): Failed to write reg index 0x0001: -19 kernel: ax88179_178a 2-9:1.0 (unnamed net_device) (uninitialized): Failed to read reg index 0x0001: -19 ... These failed operation are happening during ax88179_reset execution, so the initialization could not be correct. In order to avoid this, we need to increase the delay after reset and clock initial operations. By using these larger values, many cycles have been run and no failed operations appear. It would be better to check some status register to verify when the operation has finished, but I do not have found any available information (neither in the public datasheets nor in the manufacturer's driver). The only available information for the necessary delays is the maufacturer's driver (original values) but the proposed values are not enough for the tested devices.

The refresh reported by modetest is 60.46Hz, and the actual measurement is 60.01Hz, which is outside the expected tolerance. Adjust hporch and pixel clock to fix it. After repair, modetest and actual measurement were all 60.01Hz. Modetest refresh = Pixel CLK/ htotal* vtotal, but measurement frame rate is HS->LP cycle time(Vblanking). Measured frame rate is not only affecte by Htotal/Vtotal/pixel clock, also affected by Lane-num/PixelBit/LineTime /DSI CLK. Assume that the DSI controller could not make the mode that we requested(presumably it's PLL couldn't generate the exact pixel clock?). If you use a different DSI controller, you may need to readjust these parameters. Now this panel looks like it's only used by me on the MTK platform, so let's change this set of parameters.

2023-11-21USB: xhci-plat: fix legacy PHY double initJohan Hovold
Commits 7b8ef22ea547 ("usb: xhci: plat: Add USB phy support") and 9134c1fd0503 ("usb: xhci: plat: Add USB 3.0 phy support") added support for looking up legacy PHYs from the sysdev devicetree node and initialising them. This broke drivers such as dwc3 which manages PHYs themself as the PHYs would now be initialised twice, something which specifically can lead to resources being left enabled during suspend (e.g. with the usb_phy_generic PHY driver). As the dwc3 driver uses driver-name matching for the xhci platform device, fix this by only looking up and initialising PHYs for devices that have been matched using OF. Note that checking that the platform device has a devicetree node would currently be sufficient, but that could lead to subtle breakages in case anyone ever tries to reuse an ancestor's node.

2023-11-21usb: config: fix iteration issue in 'usb_get_bos_descriptor()'Niklas Neronin
The BOS descriptor defines a root descriptor and is the base descriptor for accessing a family of related descriptors. Function 'usb_get_bos_descriptor()' encounters an iteration issue when skipping the 'USB_DT_DEVICE_CAPABILITY' descriptor type. This results in the same descriptor being read repeatedly. To address this issue, a 'goto' statement is introduced to ensure that the pointer and the amount read is updated correctly. This ensures that the function iterates to the next descriptor instead of reading the same descriptor repeatedly.

2023-11-21usb: cdnsp: Fix deadlock issue during using NCM gadgetPawel Laszczak
The interrupt service routine registered for the gadget is a primary handler which mask the interrupt source and a threaded handler which handles the source of the interrupt. Since the threaded handler is voluntary threaded, the IRQ-core does not disable bottom halves before invoke the handler like it does for the forced-threaded handler. Due to changes in networking it became visible that a network gadget's completions handler may schedule a softirq which remains unprocessed. The gadget's completion handler is usually invoked either in hard-IRQ or soft-IRQ context. In this context it is enough to just raise the softirq because the softirq itself will be handled once that context is left. In the case of the voluntary threaded handler, there is nothing that will process pending softirqs. Which means it remain queued until another random interrupt (on this CPU) fires and handles it on its exit path or another thread locks and unlocks a lock with the bh suffix. Worst case is that the CPU goes idle and the NOHZ complains about unhandled softirqs. Disable bottom halves before acquiring the lock (and disabling interrupts) and enable them after dropping the lock. This ensures that any pending softirqs will handled right away. cc: stable@vger.kernel.org Fixes: 3d82904559f4 ("usb: cdnsp: cdns3 Add main part of Cadence USBSSP DRD Driver") Signed-off-by: Pawel Laszczak <pawell@cadence.com> Acked-by: Peter Chen <peter.chen@kernel.org> Link: https://lore.kernel.org/r/20231108093125.224963-1-pawell@cadence.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2023-11-21Revert "HID: logitech-dj: Add support for a new lightspeed receiver iteration"Jiri Kosina
This reverts commit 9d1bd9346241cd6963b58da7ffb7ed303285f684. Multiple people reported misbehaving devices and reverting this commit fixes the problem for them. As soon as the original commit author starts reacting again, we can try to figure out why he hasn't seen the issues (mismatching report descriptors?), but for the time being, fix for 6.7 by reverting.
