2024-01-26platform/x86/amd/pmf: Fix memory leak in amd_pmf_get_pb_data()Cong Liu
amd_pmf_get_pb_data() will allocate memory for the policy buffer, but does not free it if copy_from_user() fails. This leads to a memory leak.

2024-01-26x86/efistub: Give up if memory attribute protocol returns an errorArd Biesheuvel
The recently introduced EFI memory attributes protocol should be used if it exists to ensure that the memory allocation created for the kernel permits execution. This is needed for compatibility with tightened requirements related to Windows logo certification for x86 PCs. Currently, we simply strip the execute protect (XP) attribute from the entire range, but this might be rejected under some firmware security policies, and so in a subsequent patch, this will be changed to only strip XP from the executable region that runs early, and make it read-only (RO) as well. In order to catch any issues early, ensure that the memory attribute protocol works as intended, and give up if it produces spurious errors. Note that the DXE services based fallback was always based on best effort, so don't propagate any errors returned by that API.

2024-01-26drm: bridge: samsung-dsim: Don't use FORCE_STOP_STATEMichael Walle
The FORCE_STOP_STATE bit is unsuitable to force the DSI link into LP-11 mode. It seems the bridge internally queues DSI packets and when the FORCE_STOP_STATE bit is cleared, they are sent in close succession without any useful timing (this also means that the DSI lanes won't go into LP-11 mode). The length of this gibberish varies between 1ms and 5ms. This sometimes breaks an attached bridge (TI SN65DSI84 in this case). In our case, the bridge will fail in about 1 per 500 reboots. The FORCE_STOP_STATE handling was introduced to have the DSI lanes in LP-11 state during the .pre_enable phase. But as it turns out, none of this is needed at all. Between samsung_dsim_init() and samsung_dsim_set_display_enable() the lanes are already in LP-11 mode. The code as it was before commit 20c827683de0 ("drm: bridge: samsung-dsim: Fix init during host transfer") and 0c14d3130654 ("drm: bridge: samsung-dsim: Fix i.MX8M enable flow to meet spec") was correct in this regard. This patch basically reverts both commits. It was tested on an i.MX8M SoC with an SN65DSI84 bridge. The signals were probed and the DSI packets were decoded during initialization and link start-up. After this patch the first DSI packet on the link is a VSYNC packet and the timing is correct. Command mode between .pre_enable and .enable was also briefly tested by a quick hack. There was no DSI link partner which would have responded, but it was made sure the DSI packet was send on the link. As a side note, the command mode seems to just work in HS mode. I couldn't find that the bridge will handle commands in LP mode.

2024-01-26wifi: iwlwifi: fix double-free bugJohannes Berg
The storage for the TLV PC register data wasn't done like all the other storage in the drv->fw area, which is cleared at the end of deallocation. Therefore, the freeing must also be done differently, explicitly NULL'ing it out after the free, since otherwise there's a nasty double-free bug here if a file fails to load after this has been parsed, and we get another free later (e.g. because no other file exists.) Fix that by adding the missing NULL assignment.

2024-01-25nfp: flower: fix hardware offload for the transfer layer portHui Zhou
The nfp driver will merge the tp source port and tp destination port into one dword which the offset must be zero to do hardware offload. However, the mangle action for the tp source port and tp destination port is separated for tc ct action. Modify the mangle action for the FLOW_ACT_MANGLE_HDR_TYPE_TCP and FLOW_ACT_MANGLE_HDR_TYPE_UDP to satisfy the nfp driver offload check for the tp port. The mangle action provides a 4B value for source, and a 4B value for the destination, but only 2B of each contains the useful information. For offload the 2B of each is combined into a single 4B word. Since the incoming mask for the source is '0xFFFF<mask>' the shift-left will throw away the 0xFFFF part. When this gets combined together in the offload it will clear the destination field. Fix this by setting the lower bits back to 0xFFFF, effectively doing a rotate-left operation on the mask.

When a tc rule which action contains ct and the post ct entry's out port is openvswitch internal port, the merge offload flow pay with the wrong mask id of 0 will be send to the firmware. Actually, the nfp can not support hardware offload for this situation, so return EOPNOTSUPP.

2024-01-25ahci: add 43-bit DMA address quirk for ASMedia ASM1061 controllersLennert Buytenhek
With one of the on-board ASM1061 AHCI controllers (1b21:0612) on an ASUSTeK Pro WS WRX80E-SAGE SE WIFI mainboard, a controller hang was observed that was immediately preceded by the following kernel messages: ahci 0000:28:00.0: Using 64-bit DMA addresses ahci 0000:28:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0035 address=0x7fffff00000 flags=0x0000] ahci 0000:28:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0035 address=0x7fffff00300 flags=0x0000] ahci 0000:28:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0035 address=0x7fffff00380 flags=0x0000] ahci 0000:28:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0035 address=0x7fffff00400 flags=0x0000] ahci 0000:28:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0035 address=0x7fffff00680 flags=0x0000] ahci 0000:28:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0035 address=0x7fffff00700 flags=0x0000] The first message is produced by code in drivers/iommu/dma-iommu.c which is accompanied by the following comment that seems to apply: /* * Try to use all the 32-bit PCI addresses first. The original SAC vs. * DAC reasoning loses relevance with PCIe, but enough hardware and * firmware bugs are still lurking out there that it's safest not to * venture into the 64-bit space until necessary. * * If your device goes wrong after seeing the notice then likely either * its driver is not setting DMA masks accurately, the hardware has * some inherent bug in handling >32-bit addresses, or not all the * expected address bits are wired up between the device and the IOMMU. */ Asking the ASM1061 on a discrete PCIe card to DMA from I/O virtual address 0xffffffff00000000 produces the following I/O page faults: vfio-pci 0000:07:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0021 address=0x7ff00000000 flags=0x0010] vfio-pci 0000:07:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0021 address=0x7ff00000500 flags=0x0010] Note that the upper 21 bits of the logged DMA address are zero. (When asking a different PCIe device in the same PCIe slot to DMA to the same I/O virtual address, we do see all the upper 32 bits of the DMA address as 1, so this is not an issue with the chipset or IOMMU configuration on the test system.) Also, hacking libahci to always set the upper 21 bits of all DMA addresses to 1 produces no discernible effect on the behavior of the ASM1061, and mkfs/mount/scrub/etc work as without this hack. This all strongly suggests that the ASM1061 has a 43 bit DMA address limit, and this commit therefore adds a quirk to deal with this limit. This issue probably applies to (some of) the other supported ASMedia parts as well, but we limit it to the PCI IDs known to refer to ASM1061 parts, as that's the only part we know for sure to be affected by this issue at this point.

2024-01-25tsnep: Fix XDP_RING_NEED_WAKEUP for empty fill ringGerhard Engleder
The fill ring of the XDP socket may contain not enough buffers to completey fill the RX queue during socket creation. In this case the flag XDP_RING_NEED_WAKEUP is not set as this flag is only set if the RX queue is not completely filled during polling. Set XDP_RING_NEED_WAKEUP flag also if RX queue is not completely filled during XDP socket creation.
