2023-01-18drm/amd/display: Fix COLOR_SPACE_YCBCR2020_TYPE matrixJoshua Ashton
The YCC conversion matrix for RGB -> COLOR_SPACE_YCBCR2020_TYPE is missing the values for the fourth column of the matrix. The fourth column of the matrix is essentially just a value that is added given that the color is 3 components in size. These values are needed to bias the chroma from the [-1, 1] -> [0, 1] range. This fixes color being very green when using Gamescope HDR on HDMI output which prefers YCC 4:4:4.

Hao Sun reported in [1] that the current task at the entry of the helper might be gone during irq_work callback processing.

2023-01-18mm: fix a few rare cases of using swapin error pte markerPeter Xu
This patch should harden commit 15520a3f0469 ("mm: use pte markers for swap errors") on using pte markers for swapin errors on a few corner cases. 1. Propagate swapin errors across fork()s: if there're swapin errors in the parent mm, after fork()s the child should sigbus too when an error page is accessed. 2. Fix a rare condition race in pte_marker_clear() where a uffd-wp pte marker can be quickly switched to a swapin error. 3. Explicitly ignore swapin error pte markers in change_protection(). I mostly don't worry on (2) or (3) at all, but we should still have them. Case (1) is special because it can potentially cause silent data corrupt on child when parent has swapin error triggered with swapoff, but since swapin error is rare itself already it's probably not easy to trigger either. Currently there is a priority difference between the uffd-wp bit and the swapin error entry, in which the swapin error always has higher priority (e.g. we don't need to wr-protect a swapin error pte marker). If there will be a 3rd bit introduced, we'll probably need to consider a more involved approach so we may need to start operate on the bits. Let's leave that for later. This patch is tested with case (1) explicitly where we'll get corrupted data before in the child if there's existing swapin error pte markers, and after patch applied the child can be rightfully killed. We don't need to copy stable for this one since 15520a3f0469 just landed as part of v6.2-rc1, only "Fixes" applied.

2023-01-18mm/uffd: fix pte marker when fork() without fork eventPeter Xu
Patch series "mm: Fixes on pte markers". Patch 1 resolves the syzkiller report from Pengfei. Patch 2 further harden pte markers when used with the recent swapin error markers. The major case is we should persist a swapin error marker after fork(), so child shouldn't read a corrupted page. This patch (of 2): When fork(), dst_vma is not guaranteed to have VM_UFFD_WP even if src may have it and has pte marker installed. The warning is improper along with the comment. The right thing is to inherit the pte marker when needed, or keep the dst pte empty. A vague guess is this happened by an accident when there's the prior patch to introduce src/dst vma into this helper during the uffd-wp feature got developed and I probably messed up in the rebase, since if we replace dst_vma with src_vma the warning & comment it all makes sense too. Hugetlb did exactly the right here (copy_hugetlb_page_range()). Fix the general path.

If during iscsi_sw_tcp_session_create() iscsi_tcp_r2tpool_alloc() fails, userspace could be accessing the host's ipaddress attr. If we then free the session via iscsi_session_teardown() while userspace is still accessing the session we will hit a use after free bug. Set the tcp_sw_host->session after we have completed session creation and can no longer fail.

2023-01-18scsi: ufs: core: Fix devfreq deadlocksJohan Hovold
There is a lock inversion and rwsem read-lock recursion in the devfreq target callback which can lead to deadlocks. Specifically, ufshcd_devfreq_scale() already holds a clk_scaling_lock read lock when toggling the write booster, which involves taking the dev_cmd mutex before taking another clk_scaling_lock read lock. This can lead to a deadlock if another thread: 1) tries to acquire the dev_cmd and clk_scaling locks in the correct order, or 2) takes a clk_scaling write lock before the attempt to take the clk_scaling read lock a second time. Fix this by dropping the clk_scaling_lock before toggling the write booster as was done before commit 0e9d4ca43ba8 ("scsi: ufs: Protect some contexts from unexpected clock scaling"). While the devfreq callbacks are already serialised, add a second serialising mutex to handle the unlikely case where a callback triggered through the devfreq sysfs interface is racing with a request to disable clock scaling through the UFS controller 'clkscale_enable' sysfs attribute. This could otherwise lead to the write booster being left disabled after having disabled clock scaling. Also take the new mutex in ufshcd_clk_scaling_allow() to make sure that any pending write booster update has completed on return.

2023-01-18cifs: do not include page data when checking signatureEnzo Matsumiya
On async reads, page data is allocated before sending. When the response is received but it has no data to fill (e.g. STATUS_END_OF_FILE), __calc_signature() will still include the pages in its computation, leading to an invalid signature check. This patch fixes this by not setting the async read smb_rqst page data (zeroed by default) if its got_bytes is 0. This can be reproduced/verified with xfstests generic/465.

The ACPI PRM address space handler calls efi_call_virt_pointer() to execute PRM firmware code, but doing so is only permitted when the EFI runtime environment is available. Otherwise, such calls are guaranteed to result in a crash, and must therefore be avoided. Given that the EFI runtime services may become unavailable after a crash occurring in the firmware, we need to check this each time the PRM address space handler is invoked. If the EFI runtime services were not available at registration time to being with, don't install the address space handler at all.

Always allow switching away via vga-switcheroo if the display is uninitalized. Instead prevent switching to i915 if the device has not been initialized.

In the case of vga-switcheroo, we want to allow a switch away from i915's device. So run vga_switcheroo_process_delayed_switch() and test in the switcheroo callbacks if the i915 device is available.

betopff_init() only checks the total sum of the report counts for each report field to be at least 4, but hid_betopff_play() expects 4 report fields. A device advertising an output report with one field and 4 report counts would pass the check but crash the kernel with a NULL pointer dereference in hid_betopff_play().

2023-01-18counter: fix dependency references for config MICROCHIP_TCB_CAPTURELukas Bulwahn
Commit dfeef15e73ca ("counter: microchip-tcp-capture: Add appropriate arch deps for TCP driver") intends to add appropriate dependencies for the config MICROCHIP_TCB_CAPTURE. It however prefixes the intended configs with CONFIG, but in Kconfig files in contrast to source files, the configs are referenced to without prefixing them with CONFIG. Fix the dependency references due to this minor misconception.

lockdep complains with the following lock/unlock sequence: lock_sock(sk); write_lock_bh(&sk->sk_callback_lock); [1] release_sock(sk); [2] write_unlock_bh(&sk->sk_callback_lock); We need to swap [1] and [2] to fix this issue.

2023-01-18gpiolib: acpi: Add a ignore wakeup quirk for Clevo NL5xRUMario Limonciello
commit 1796f808e4bb ("HID: i2c-hid: acpi: Stop setting wakeup_capable") changed the policy such that I2C touchpads may be able to wake up the system by default if the system is configured as such. However on Clevo NL5xRU there is a mistake in the ACPI tables that the TP_ATTN# signal connected to GPIO 9 is configured as ActiveLow and level triggered but connected to a pull up. As soon as the system suspends the touchpad loses power and then the system wakes up. To avoid this problem, introduce a quirk for this model that will prevent the wakeup capability for being set for GPIO 9.

2023-01-18gpiolib: acpi: Allow ignoring wake capability on pins that aren't in _AEIMario Limonciello
Using the `ignore_wake` quirk or module parameter doesn't work for any pin that has been specified in the _CRS instead of _AEI. Extend the `acpi_gpio_irq_is_wake` check to cover both places.
