2023-10-17drm/i915: Retry gtt fault when out of fence registersVille Syrjälä
If we can't find a free fence register to handle a fault in the GMADR range just return VM_FAULT_NOPAGE without populating the PTE so that userspace will retry the access and trigger another fault. Eventually we should find a free fence and the fault will get properly handled. A further improvement idea might be to reserve a fence (or one per CPU?) for the express purpose of handling faults without having to retry. But that would require some additional work. Looks like this may have gotten broken originally by commit 39965b376601 ("drm/i915: don't trash the gtt when running out of fences") as that changed the errno to -EDEADLK which wasn't handle by the gtt fault code either. But later in commit 2feeb52859fc ("drm/i915/gt: Fix -EDEADLK handling regression") I changed it again to -ENOBUFS as -EDEADLK was now getting used for the ww mutex dance. So this fix only makes sense after that last commit.

2023-10-17drm/i915/cx0: Only clear/set the Pipe Reset bit of the PHY Lanes OwnedKhaled Almahallawy
Currently, with MFD/pin assignment D, the driver clears the pipe reset bit of lane 1 which is not owned by display. This causes the display to block S0iX. By not clearing this bit for lane 1 and keeping whatever default, S0ix started to work. This is already what the driver does at the end of the phy lane reset sequence (Step#8) Bspec: 65451 Fixes: 619a06dba6fa ("drm/i915/mtl: Reset only one lane in case of MFD") Cc: Mika Kahola <mika.kahola@intel.com> Cc: Gustavo Sousa <gustavo.sousa@intel.com> Signed-off-by: Khaled Almahallawy <khaled.almahallawy@intel.com> Reviewed-by: Gustavo Sousa <gustavo.sousa@intel.com> Signed-off-by: Radhakrishna Sripada <radhakrishna.sripada@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20231005001310.154396-1-khaled.almahallawy@intel.com (cherry picked from commit 4a07f063d20c46524f00976f4537de72d9f31c4e) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>

2023-10-16drm/mediatek: Correctly free sg_table in gem prime vmapChen-Yu Tsai
The MediaTek DRM driver implements GEM PRIME vmap by fetching the sg_table for the object, iterating through the pages, and then vmapping them. In essence, unlike the GEM DMA helpers which vmap when the object is first created or imported, the MediaTek version does it on request. Unfortunately, the code never correctly frees the sg_table contents. This results in a kernel memory leak. On a Hayato device with a text console on the internal display, this results in the system running out of memory in a few days from all the console screen cursor updates. Add sg_free_table() to correctly free the contents of the sg_table. This was missing despite explicitly required by mtk_gem_prime_get_sg_table(). Also move the "out" shortcut label to after the kfree() call for the sg_table. Having sg_free_table() together with kfree() makes more sense. The shortcut is only used when the object already has a kernel address, in which case the pointer is NULL and kfree() does nothing. Hence this change causes no functional change.

2023-10-16pinctrl: qcom: lpass-lpi: fix concurrent register updatesKrzysztof Kozlowski
The Qualcomm LPASS LPI pin controller driver uses one lock for guarding Read-Modify-Write code for slew rate registers. However the pin configuration and muxing registers have exactly the same RMW code but are not protected. Pin controller framework does not provide locking here, thus it is possible to trigger simultaneous change of pin configuration registers resulting in non-atomic changes. Protect from concurrent access by re-using the same lock used to cover the slew rate register. Using the same lock instead of adding second one will make more sense, once we add support for newer Qualcomm SoC, where slew rate is configured in the same register as pin configuration/muxing.

2023-10-16mtd: rawnand: Ensure the nand chip supports cached readsRouven Czerwinski
Both the JEDEC and ONFI specification say that read cache sequential support is an optional command. This means that we not only need to check whether the individual controller supports the command, we also need to check the parameter pages for both ONFI and JEDEC NAND flashes before enabling sequential cache reads. This fixes support for NAND flashes which don't support enabling cache reads, i.e. Samsung K9F4G08U0F or Toshiba TC58NVG0S3HTA00.

Commit 295525e29a5b ("virtio_net: merge dma operations when filling mergeable buffers") unmaps the buffer with DMA_ATTR_SKIP_CPU_SYNC when the dma->ref is zero. We do that with DMA_ATTR_SKIP_CPU_SYNC, because we do not want to do the sync for the entire page_frag. But that misses the sync for the current area.

2023-10-13Input: synaptics-rmi4 - handle reset delay when using SMBus trsnsportDmitry Torokhov
Touch controllers need some time after receiving reset command for the firmware to finish re-initializing and be ready to respond to commands from the host. The driver already had handling for the post-reset delay for I2C and SPI transports, this change adds the handling to SMBus-connected devices. SMBus devices are peculiar because they implement legacy PS/2 compatibility mode, so reset is actually issued by psmouse driver on the associated serio port, after which the control is passed to the RMI4 driver with SMBus companion device. Note that originally the delay was added to psmouse driver in 92e24e0e57f7 ("Input: psmouse - add delay when deactivating for SMBus mode"), but that resulted in an unwanted delay in "fast" reconnect handler for the serio port, so it was decided to revert the patch and have the delay being handled in the RMI4 driver, similar to the other transports.

2023-10-13Input: psmouse - fix fast_reconnect function for PS/2 modeJeffery Miller
When the SMBus connection is attempted psmouse_smbus_init() sets the fast_reconnect pointer to psmouse_smbus_reconnecti(). If SMBus initialization fails, elantech_setup_ps2() and synaptics_init_ps2() will fallback to PS/2 mode, replacing the psmouse private data. This can cause issues on resume, since psmouse_smbus_reconnect() expects to find an instance of struct psmouse_smbus_dev in psmouse->private. The issue was uncovered when in 92e24e0e57f7 ("Input: psmouse - add delay when deactivating for SMBus mode") psmouse_smbus_reconnect() started attempting to use more of the data structure. The commit was since reverted, not because it was at fault, but because there was found a better way of doing what it was attempting to do. Fix the problem by resetting the fast_reconnect pointer in psmouse structure in elantech_setup_ps2() and synaptics_init_ps2() when the PS/2 mode is used.

2023-10-13ice: reset first in crash dump kernelsJesse Brandeburg
When the system boots into the crash dump kernel after a panic, the ice networking device may still have pending transactions that can cause errors or machine checks when the device is re-enabled. This can prevent the crash dump kernel from loading the driver or collecting the crash data. To avoid this issue, perform a function level reset (FLR) on the ice device via PCIe config space before enabling it on the crash kernel. This will clear any outstanding transactions and stop all queues and interrupts. Restore the config space after the FLR, otherwise it was found in testing that the driver wouldn't load successfully. The following sequence causes the original issue: - Load the ice driver with modprobe ice - Enable SR-IOV with 2 VFs: echo 2 > /sys/class/net/eth0/device/sriov_num_vfs - Trigger a crash with echo c > /proc/sysrq-trigger - Load the ice driver again (or let it load automatically) with modprobe ice - The system crashes again during pcim_enable_device() Fixes: 837f08fdecbe ("ice: Add basic driver framework for Intel(R) E800 Series") Reported-by: Vishal Agrawal <vagrawal@redhat.com> Reviewed-by: Jay Vosburgh <jay.vosburgh@canonical.com> Reviewed-by: Przemek Kitszel <przemyslaw.kitszel@intel.com> Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Tested-by: Pucha Himasekhar Reddy <himasekharx.reddy.pucha@intel.com> (A Contingent worker at Intel) Link: https://lore.kernel.org/r/20231011233334.336092-3-jacob.e.keller@intel.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-10-13i40e: prevent crash on probe if hw registers have invalid valuesMichal Schmidt
The hardware provides the indexes of the first and the last available queue and VF. From the indexes, the driver calculates the numbers of queues and VFs. In theory, a faulty device might say the last index is smaller than the first index. In that case, the driver's calculation would underflow, it would attempt to write to non-existent registers outside of the ioremapped range and crash. I ran into this not by having a faulty device, but by an operator error. I accidentally ran a QE test meant for i40e devices on an ice device. The test used 'echo i40e > /sys/...ice PCI device.../driver_override', bound the driver to the device and crashed in one of the wr32 calls in i40e_clear_hw. Add checks to prevent underflows in the calculations of num_queues and num_vfs. With this fix, the wrong device probing reports errors and returns a failure without crashing.

2023-10-13tcp: allow again tcp_disconnect() when threads are waitingPaolo Abeni
As reported by Tom, .NET and applications build on top of it rely on connect(AF_UNSPEC) to async cancel pending I/O operations on TCP socket. The blamed commit below caused a regression, as such cancellation can now fail. As suggested by Eric, this change addresses the problem explicitly causing blocking I/O operation to terminate immediately (with an error) when a concurrent disconnect() is executed. Instead of tracking the number of threads blocked on a given socket, track the number of disconnect() issued on such socket. If such counter changes after a blocking operation releasing and re-acquiring the socket lock, error out the current operation.

2023-10-13net: dsa: bcm_sf2: Fix possible memory leak in bcm_sf2_mdio_register()Jinjie Ruan
In bcm_sf2_mdio_register(), the class_find_device() will call get_device() to increment reference count for priv->master_mii_bus->dev if of_mdio_find_bus() succeeds. If mdiobus_alloc() or mdiobus_register() fails, it will call get_device() twice without decrement reference count for the device. And it is the same if bcm_sf2_mdio_register() succeeds but fails in bcm_sf2_sw_probe(), or if bcm_sf2_sw_probe() succeeds. If the reference count has not decremented to zero, the dev related resource will not be freed. So remove the get_device() in bcm_sf2_mdio_register(), and call put_device() if mdiobus_alloc() or mdiobus_register() fails and in bcm_sf2_mdio_unregister() to solve the issue. And as Simon suggested, unwind from errors for bcm_sf2_mdio_register() and just return 0 if it succeeds to make it cleaner.
