2022-10-22usb: gadget: uvc: fix sg handling in error caseDan Vacura
If there is a transmission error the buffer will be returned too early, causing a memory fault as subsequent requests for that buffer are still queued up to be sent. Refactor the error handling to wait for the final request to come in before reporting back the buffer to userspace for all transfer types (bulk/isoc/isoc_sg). This ensures userspace knows if the frame was successfully sent.

2022-10-22usb: gadget: uvc: fix dropped frame after missed isocDan Vacura
With the re-use of the previous completion status in 0d1c407b1a749 ("usb: dwc3: gadget: Return proper request status") it could be possible that the next frame would also get dropped if the current frame has a missed isoc error. Ensure that an interrupt is requested for the start of a new frame.

2022-10-22usb: dwc3: gadget: Don't delay End Transfer on delayed_statusThinh Nguyen
The gadget driver may wait on the request completion when it sets the USB_GADGET_DELAYED_STATUS. Make sure that the End Transfer command can go through if the dwc->delayed_status is set so that the request can complete. When the delayed_status is set, the Setup packet is already processed, and the next phase should be either Data or Status. It's unlikely that the host would cancel the control transfer and send a new Setup packet during End Transfer command. But if that's the case, we can try again when ep0state returns to EP0_SETUP_PHASE.

Currently `sp_indiff` is cleaned when driver is removed. This will cause problem in multi-PF/multi-host case, considering one PF is removed while another is still in use. Since `sp_indiff` is the application firmware property, it should only be cleaned when the firmware is unloaded. Now let management firmware to clean it when necessary, driver only set it.

The offset 12 (bit-rate) of EEPROM SFP DAC (passive) cables is expected to be in the range 0x64 to 0x68. However, the 5 meter and 7 meter Molex passive cables have the rate ceiling 0x78 at offset 12.

The current XGBE code assumes that offset 6 of EEPROM SFP DAC (passive) cables is NULL. However, some cables (the 5 meter and 7 meter Molex passive cables) have non-zero data at offset 6. Fix the logic by moving the passive cable check above the active checks, so as not to be improperly identified as an active cable.

PLL control setting(RRC) is needed only in fixed PHY configuration to fix the peer-peer issues. Without the PLL control setting, the link up takes longer time in a fixed phy configuration. Driver implements SW RRC for Autoneg On configuration, hence PLL control setting (RRC) is not needed for AN On configuration, and can be skipped. Also, PLL re-initialization is not needed for PHY Power Off and RRC commands. Otherwise, they lead to mailbox errors. Added the changes accordingly.

2022-10-21drm/bridge: ps8640: Add back the 50 ms mystery delay after HPDDouglas Anderson
Back in commit 826cff3f7ebb ("drm/bridge: parade-ps8640: Enable runtime power management") we removed a mysterious 50 ms delay because "Parade's support [couldn't] explain what the delay [was] for". While I'm always a fan of removing mysterious delays, I suspect that we need this mysterious delay to avoid some problems. Specifically, what I found recently is that on sc7180-trogdor-homestar sometimes the AUX backlight wasn't initializing properly. Some debugging showed that the drm_dp_dpcd_read() function that the AUX backlight driver was calling was returning bogus data about 1% of the time when I booted up. This confused drm_panel_dp_aux_backlight(). From continued debugging: - If I retried the read then the read worked just fine. - If I added a loop to perform the same read that drm_panel_dp_aux_backlight() was doing 30 times at bootup I could see that some percentage of the time the first read would give bogus data but all 29 additional reads would always be fine. - If I added a large delay _after_ powering on the panel but before powering on PS8640 I could still reproduce the problem. - If I added a delay after PS8640 powered on then I couldn't reproduce the problem. - I couldn't reproduce the problem on a board with the same panel but the ti-sn65dsi86 bridge chip. To me, the above indicated that there was a problem with PS8640 and not the panel. I don't really have any insight into what's going on in the MCU, but my best guess is that when the MCU itself sees the HPD go high that it does some AUX transfers itself and this is confusing things. Let's go back and add back in the mysterious 50 ms delay. We only want to do this the first time we see HPD go high after booting the MCU, not every time we double-check HPD. With this, the backlight initializes reliably on homestar.

2022-10-21efi: runtime: Don't assume virtual mappings are missing if VA == PA == 0Ard Biesheuvel
The generic EFI stub can be instructed to avoid SetVirtualAddressMap(), and simply run with the firmware's 1:1 mapping. In this case, it populates the virtual address fields of the runtime regions in the memory map with the physical address of each region, so that the mapping code has to be none the wiser. Only if SetVirtualAddressMap() fails, the virtual addresses are wiped and the kernel code knows that the regions cannot be mapped. However, wiping amounts to setting it to zero, and if a runtime region happens to live at physical address 0, its valid 1:1 mapped virtual address could be mistaken for a wiped field, resulting on loss of access to the EFI services at runtime.

The linker script symbol definition that captures the size of the compressed payload inside the zboot decompressor (which is exposed via the image header) refers to '.' for the end of the region, which does not give the correct result as the expression is not placed at the end of the payload. So use the symbol name explicitly. Signed-off-by: Ard Biesheuvel <ardb@kernel.org>

2022-10-21efi: efivars: Fix variable writes without query_variable_store()Ard Biesheuvel
Commit bbc6d2c6ef22 ("efi: vars: Switch to new wrapper layer") refactored the efivars layer so that the 'business logic' related to which UEFI variables affect the boot flow in which way could be moved out of it, and into the efivarfs driver. This inadvertently broke setting variables on firmware implementations that lack the QueryVariableInfo() boot service, because we no longer tolerate a EFI_UNSUPPORTED result from check_var_size() when calling efivar_entry_set_get_size(), which now ends up calling check_var_size() a second time inadvertently. If QueryVariableInfo() is missing, we support writes of up to 64k - let's move that logic into check_var_size(), and drop the redundant call.

2022-10-21efi: ssdt: Don't free memory if ACPI table was loaded successfullyArd Biesheuvel
Amadeusz reports KASAN use-after-free errors introduced by commit 3881ee0b1edc ("efi: avoid efivars layer when loading SSDTs from variables"). The problem appears to be that the memory that holds the new ACPI table is now freed unconditionally, instead of only when the ACPI core reported a failure to load the table. So let's fix this, by omitting the kfree() on success.

2022-10-21efi: libstub: Remove zboot signing from build optionsArd Biesheuvel
The zboot decompressor series introduced a feature to sign the PE/COFF kernel image for secure boot as part of the kernel build. This was necessary because there are actually two images that need to be signed: the kernel with the EFI stub attached, and the decompressor application. This is a bit of a burden, because it means that the images must be signed on the the same system that performs the build, and this is not realistic for distros. During the next cycle, we will introduce changes to the zboot code so that the inner image no longer needs to be signed. This means that the outer PE/COFF image can be handled as usual, and be signed later in the release process. Let's remove the associated Kconfig options now so that they don't end up in a LTS release while already being deprecated. Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
2022-10-21iommu/vt-d: Clean up si_domain in the init_dmars() error pathJerry Snitselaar
A splat from kmem_cache_destroy() was seen with a kernel prior to commit ee2653bbe89d ("iommu/vt-d: Remove domain and devinfo mempool") when there was a failure in init_dmars(), because the iommu_domain cache still had objects. While the mempool code is now gone, there still is a leak of the si_domain memory if init_dmars() fails. So clean up si_domain in the init_dmars() error path.

2022-10-21iommu/vt-d: Use rcu_lock in get_resv_regionsLu Baolu
Commit 5f64ce5411b46 ("iommu/vt-d: Duplicate iommu_resv_region objects per device list") converted rcu_lock in get_resv_regions to dmar_global_lock to allow sleeping in iommu_alloc_resv_region(). This introduced possible recursive locking if get_resv_regions is called from within a section where intel_iommu_init() already holds dmar_global_lock. Especially, after commit 57365a04c921 ("iommu: Move bus setup to IOMMU device registration"), below lockdep splats could always be seen. ============================================ WARNING: possible recursive locking detected 6.0.0-rc4+ #325 Tainted: G I -------------------------------------------- swapper/0/1 is trying to acquire lock: ffffffffa8a18c90 (dmar_global_lock){++++}-{3:3}, at: intel_iommu_get_resv_regions+0x25/0x270 but task is already holding lock: ffffffffa8a18c90 (dmar_global_lock){++++}-{3:3}, at: intel_iommu_init+0x36d/0x6ea ...
