| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The race condition around the ECCCLR register access happens in the IRQ disable method called in the device remove() procedure and in the ECC IRQ handler: 1. Enable IRQ: a. ECCCLR = EN_CE | EN_UE 2. Disable IRQ: a. ECCCLR = 0 3. IRQ handler: a. ECCCLR = CLR_CE | CLR_CE_CNT | CLR_CE | CLR_CE_CNT b. ECCCLR = 0 c. ECCCLR = EN_CE | EN_UE So if the IRQ disabling procedure is called concurrently with the IRQ handler method the IRQ might be actually left enabled due to the statement 3c. The root cause of the problem is that ECCCLR register (which since v3.10a has been called as ECCCTL) has intermixed ECC status data clear flags and the IRQ enable/disable flags. Thus the IRQ disabling (clear EN flags) and handling (write 1 to clear ECC status data) procedures must be serialised around the ECCCTL register modification to prevent the race. So fix the problem described above by adding the spin-lock around the ECCCLR modifications and preventing the IRQ-handler from modifying the IRQs enable flags (there is no point in disabling the IRQ and then re-enabling it again within a single IRQ handler call, see the statements 3a/3b and 3c above).

| * | | drm/i915/bios: Fix parsing backlight BDB dataKarthikeyan Ramasubramanian2024-05-072-20/+4

Commit 700034566d68 ("drm/i915/bios: Define more BDB contents") updated the backlight BDB data accordingly. This broke the parsing of backlight BDB data in VBT for versions 236 - 238 (both inclusive) and hence the backlight controls are not responding on units with the concerned BDB version. backlight_control information has been present in backlight BDB data from at least BDB version 191 onwards, if not before. Hence this patch extracts the backlight_control information for BDB version 191 or newer. Tested on Chromebooks using Jasperlake SoC (reports bdb->version = 236). Tested on Chromebooks using Raptorlake SoC (reports bdb->version = 251). v2: removed checking the block size of the backlight BDB data [vsyrjala: this is completely safe thanks to commit e163cfb4c96d ("drm/i915/bios: Make copies of VBT data blocks")] Fixes: 700034566d68 ("drm/i915/bios: Define more BDB contents") Cc: stable@vger.kernel.org Cc: Jani Nikula <jani.nikula@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Karthikeyan Ramasubramanian <kramasub@chromium.org> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240221180622.v2.1.I0690aa3e96a83a43b3fc33f50395d334b2981826@changeid Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> (cherry picked from commit c286f6a973c66c0d993ecab9f7162c790e7064c8) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>

Additionally, one of the GPIO chip's lines is also in the release process and holds the notifier chain's read rwsem. Consequently, a race condition leads to the use-after-free of watched_lines. Here is the typical stack when issue happened: [free] gpio_chrdev_release() --> bitmap_free(cdev->watched_lines) <-- freed --> blocking_notifier_chain_unregister() --> down_write(&nh->rwsem) <-- waiting rwsem --> __down_write_common() --> rwsem_down_write_slowpath() --> schedule_preempt_disabled() --> schedule() [use] st54spi_gpio_dev_release() --> gpio_free() --> gpiod_free() --> gpiod_free_commit() --> gpiod_line_state_notify() --> blocking_notifier_call_chain() --> down_read(&nh->rwsem); <-- held rwsem --> notifier_call_chain() --> lineinfo_changed_notify() --> test_bit(xxxx, cdev->watched_lines) <-- use after free The side effect of the use-after-free issue is that a GPIO line event is being generated for userspace where it shouldn't. However, since the chrdev is being closed, userspace won't have the chance to read that event anyway. To fix the issue, call the bitmap_free() function after the unregistration of lineinfo_changed_nb notifier chain.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We used a per-descriptor SRCU struct in order to not impose a wait with synchronize_srcu() for descriptor X on read-only operations of descriptor Y.

Rework the code to not wait until all read-only users are done with reading the label but instead atomically replace the label pointer and schedule its release after all read-only critical sections are done. To that end wrap the descriptor label in a struct that also contains the rcu_head struct required for deferring tasks using call_srcu() and stop using kstrdup_const() as we're required to allocate memory anyway. Just allocate enough for the label string and rcu_head in one go.

This is why the rsp_wait_list exists (for async handling of these cmds, we move them to a pending list). Furthermore, it is possible that the ctrl cm times out, resulting in a connect-error cm event. in this case we hit a bad deref [1] because in nvmet_rdma_free_rsps we assume that all the responses are in the free list. We are freeing the cmds array anyways, so don't even bother to remove the rsp from the free_list.

CS is a regular GPIO, and therefore always driven. Currently, the controller is enabled in the transfer_one() callback, which runs after CS is asserted. Therefore, there is a period where the SPI pins are floating while CS is asserted, making it possible for stray signals to disrupt communications. An analogous problem occurs at the end of the transfer when the controller is disabled before CS is released. This problem can be reliably observed by enabling the pull-up (if CPOL=0) or pull-down (if CPOL=1) on the clock pin. This will cause two extra unintended clock edges per transfer, when the controller is enabled and disabled. Note that this bug is likely not present on the STM32H7, because this driver sets the AFCNTR bit (not supported on F4/F7), which keeps the SPI pins driven even while the controller is disabled. Enabling/disabling the controller as part of runtime PM was suggested as an alternative approach, but this breaks the driver on the STM32MP1 (see [1]). The following quote from the manual may explain this: > To restart the internal state machine properly, SPI is strongly > suggested to be disabled and re-enabled before next transaction starts > despite its setting is not changed. This patch has been tested on an STM32F746 with a MAX14830 UART expander.

This always took precedence over driver's def_domain_type(). Commit 59ddce4418da ("iommu: Reorganize iommu_get_default_domain_type() to respect def_domain_type()") changed the behaviour. Current code calls def_domain_type() but if it doesn't return IOMMU_DOMAIN_DMA for untrusted device it throws error. This results in IOMMU group (and potentially IOMMU itself) in undetermined state. This patch adds untrusted check in AMD IOMMU driver code. So that it allows eGPUs behind Thunderbolt work again. Fine tuning amd_iommu_def_domain_type() will be done later.

Add a spinlock around the complete_all() in ccp_raw_event() and reinit_completion() in send_usb_cmd() to prevent race issues.
