commit 15e4c1f upstream. The driver's fsync() is supposed to flush any pending operation to hardware. It is implemented in this driver by cancelling the queued deferred IO first, then schedule it for "immediate execution" by calling schedule_delayed_work() again with delay=0. However, setting delay=0 only means the work is scheduled immediately, it does not mean the work is executed immediately. There is no guarantee that the work is finished after schedule_delayed_work() returns. After this driver's fsync() returns, there can still be pending work. Furthermore, if close() is called by users immediately after fsync(), the pending work gets cancelled and fsync() may do nothing. To ensure that the deferred IO completes, use flush_delayed_work() instead. Write operations to this driver either write to the device directly, or invoke schedule_delayed_work(); so by flushing the workqueue, it can be guaranteed that all previous writes make it to the device.

… size commit 6f64f86 upstream. Before calling add partition or resize partition, there is no check on whether the length is aligned with the logical block size. If the logical block size of the disk is larger than 512 bytes, then the partition size maybe not the multiple of the logical block size, and when the last sector is read, bio_truncate() will adjust the bio size, resulting in an IO error if the size of the read command is smaller than the logical block size.If integrity data is supported, this will also result in a null pointer dereference when calling bio_integrity_free.

commit 21528c6 upstream. Documentation/filesystems/ramfs-rootfs-initramfs.rst states: If CONFIG_TMPFS is enabled, rootfs will use tmpfs instead of ramfs by default. To force ramfs, add "rootfstype=ramfs" to the kernel command line. This currently does not work when root= is provided since then saved_root_name contains a string and rootfstype= is ignored. Therefore, ramfs is currently always chosen when root= is provided. The current behavior for rootfs's filesystem is: root= | rootfstype= | chosen rootfs filesystem ------------+-------------+-------------------------- unspecified | unspecified | tmpfs unspecified | tmpfs | tmpfs unspecified | ramfs | ramfs provided | ignored | ramfs rootfstype= should be respected regardless whether root= is given, as shown below: root= | rootfstype= | chosen rootfs filesystem ------------+-------------+-------------------------- unspecified | unspecified | tmpfs (as before) unspecified | tmpfs | tmpfs (as before) unspecified | ramfs | ramfs (as before) provided | unspecified | ramfs (compatibility with before) provided | tmpfs | tmpfs (new) provided | ramfs | ramfs (new) This table represents the new behavior.

commit da9065c upstream. In min_key_size_set(): if (val > hdev->le_max_key_size || val < SMP_MIN_ENC_KEY_SIZE) return -EINVAL; hci_dev_lock(hdev); hdev->le_min_key_size = val; hci_dev_unlock(hdev); In max_key_size_set(): if (val > SMP_MAX_ENC_KEY_SIZE || val < hdev->le_min_key_size) return -EINVAL; hci_dev_lock(hdev); hdev->le_max_key_size = val; hci_dev_unlock(hdev); The atomicity violation occurs due to concurrent execution of set_min and set_max funcs.Consider a scenario where setmin writes a new, valid 'min' value, and concurrently, setmax writes a value that is greater than the old 'min' but smaller than the new 'min'. In this case, setmax might check against the old 'min' value (before acquiring the lock) but write its value after the 'min' has been updated by setmin. This leads to a situation where the 'max' value ends up being smaller than the 'min' value, which is an inconsistency. This possible bug is found by an experimental static analysis tool developed by our team, BassCheck[1]. This tool analyzes the locking APIs to extract function pairs that can be concurrently executed, and then analyzes the instructions in the paired functions to identify possible concurrency bugs including data races and atomicity violations. The above possible bug is reported when our tool analyzes the source code of Linux 5.17. To resolve this issue, it is suggested to encompass the validity checks within the locked sections in both set_min and set_max funcs. The modification ensures that the validation of 'val' against the current min/max values is atomic, thus maintaining the integrity of the settings. With this patch applied, our tool no longer reports the bug, with the kernel configuration allyesconfig for x86_64. Due to the lack of associated hardware, we cannot test the patch in runtime testing, and just verify it according to the code logic.

commit afc9568 upstream. In some cases the firmware expects cbndx 1 to be assigned to the GMU, so we also want the default domain for the GMU to be an identy domain. This way it does not get a context bank assigned. Without this, both of_dma_configure() and drm/msm's iommu_domain_attach() will trigger allocating and configuring a context bank. So GMU ends up attached to both cbndx 1 and later cbndx 2. This arrangement seemingly confounds and surprises the firmware if the GPU later triggers a translation fault, resulting (on sc8280xp / lenovo x13s, at least) in the SMMU getting wedged and the GPU stuck without memory access.

commit e874a79 upstream. Commit 495184a ("mt76: mt7915: add support for applying pre-calibration data") was fundamentally broken and never worked. The idea (before NVMEM support) was to expand the MTD function and pass an additional offset. For normal EEPROM load the offset would always be 0. For the purpose of precal loading, an offset was passed that was internally the size of EEPROM, since precal data is right after the EEPROM. Problem is that the offset value passed is never handled and is actually overwrite by offset = be32_to_cpup(list); ret = mtd_read(mtd, offset, len, &retlen, eep); resulting in the passed offset value always ingnored. (and even passing garbage data as precal as the start of the EEPROM is getting read) Fix this by adding to the current offset value, the offset from DT to correctly read the piece of data at the requested location.

commit b3943b3 upstream. Ever since introduction in the commit 0c81733 ("rtl8192ce: Add new driver") the rtlwifi code has, according to comments, attempted to disable/enable ASPM of the upstream bridge by writing into its LNKCTL register. However, the code has never been correct because it performs the writes to the device instead of the upstream bridge. Worse yet, the offset where the PCIe capabilities reside is derived from the offset of the upstream bridge. As a result, the write will use an offset on the device that does not relate to the LNKCTL register making the ASPM disable/enable code outright dangerous. Because of those problems, there is no indication that the driver needs disable/enable ASPM on the upstream bridge. As the Capabilities offset is not correctly calculated for the write to target device's LNKCTL register, the code is not disabling/enabling device's ASPM either. Therefore, just remove the upstream bridge related ASPM disable/enable code entirely. The upstream bridge related ASPM code was the only user of the struct mp_adapter members num4bytes, pcibridge_pciehdr_offset, and pcibridge_linkctrlreg so those are removed as well. Note: This change does not remove the code related to changing the device's ASPM on purpose (which is independent of this flawed code related to upstream bridge's ASPM).

commit 5894d00 upstream. The rtlwifi driver comes with custom code to write into PCIe Link Control register. RMW access for the Link Control register requires locking that is already provided by the standard PCIe capability accessors. Convert the custom RMW code writing into LNKCTL register to standard RMW capability accessors. The accesses are changed to cover the full LNKCTL register instead of touching just a single byte of the register.

commit f0dd488 upstream. AP BSSID configuration is missing at AP start. Without this fix, FW returns STA interface MAC address after first init. When hostapd restarts, it gets MAC address from netdev before driver sets STA MAC to netdev again. Now MAC address between hostapd and net interface are different causes STA cannot connect to AP. After that MAC address of uap0 mlan0 become the same. And issue disappears after following hostapd restart (another issue is AP/STA MAC address become the same). This patch fixes the issue cleanly.

commit 2217fff upstream. Commit 6f5e193 ("PCI: dwc: Fix dw_pcie_ep_raise_msix_irq() to get correct MSI-X table address") modified dw_pcie_ep_raise_msix_irq() to support iATUs which require a specific alignment. However, this support cannot have been properly tested. The whole point is for the iATU to map an address that is aligned, using dw_pcie_ep_map_addr(), and then let the writel() write to ep->msi_mem + aligned_offset. Thus, modify the address that is mapped such that it is aligned. With this change, dw_pcie_ep_raise_msix_irq() matches the logic in dw_pcie_ep_raise_msi_irq().

… touches commit 5022960 upstream. There appear to be a few different ways that Wacom devices can deal with confidence: 1. If the device looses confidence in a touch, it will first clear the tipswitch flag in one report, and then clear the confidence flag in a second report. This behavior is used by e.g. DTH-2452. 2. If the device looses confidence in a touch, it will clear both the tipswitch and confidence flags within the same report. This behavior is used by some AES devices. 3. If the device looses confidence in a touch, it will clear *only* the confidence bit. The tipswitch bit will remain set so long as the touch is tracked. This behavior may be used in future devices. The driver does not currently handle situation 3 properly. Touches that loose confidence will remain "in prox" and essentially frozen in place until the tipswitch bit is finally cleared. Not only does this result in userspace seeing a stuck touch, but it also prevents pen arbitration from working properly (the pen won't send events until all touches are up, but we don't currently process events from non-confident touches). This commit centralizes the checking of the confidence bit in the wacom_wac_finger_slot() function and has 'prox' depend on it. In the case where situation 3 is encountered, the treat the touch as though it was removed, allowing both userspace and the pen arbitration to act normally.

However this cannot be later used with an AF_XDP socket for the umem buffer, because it creates a mapping with VM_IO that is not backed by an instance of struct page. This replaces the driver with one that uses a cooperating reserved memory node to register SRAM as part of system memory and reserve it so that it can later be mapped into userspace, used with AF_XDP, etc. but will not be unexpectedly assigned to userspace otherwise. The memory is also suitably mapped for use with POSIX IPC or any other use which requires mapping it back into kernel space via get_user_pages, and caching is enabled as usual for regular memory mapped into userspace.

Updating flash partitions in accordance with uboot
…ers terminated while a callback is pending
Split the memory and peripheral burst size configuration to improve interconnect usage by not forcing the two to match. Each peripheral will need to correctly configure some combination of burst settings in the driver in order to achieve better performance

When configured to operate in non-dma mode, recent adi_uart4 driver changes require the interrupts to be named. Copy all these missing names from the sc598 to all the other platforms.
dma_request_chan() returns an ERRPTR on failure, not a null pointer. This will result in a crash when the driver operates without DMA.

[ Upstream commit e3e82fc ] When creating ceq_0 during probing irdma, cqp.sc_cqp will be sent as a cqp_request to cqp->sc_cqp.sq_ring. If the request is pending when removing the irdma driver or unplugging its aux device, cqp.sc_cqp will be dereferenced as wrong struct in irdma_free_pending_cqp_request().
