[PATCH] x86/fpu: Ensure XFD state on signal delivery

by Chang S. Bae

Sean reported [1] the following splat when running KVM tests: WARNING: CPU: 232 PID: 15391 at xfd_validate_state+0x65/0x70 Call Trace: <TASK> fpu__clear_user_states+0x9c/0x100 arch_do_signal_or_restart+0x142/0x210 exit_to_user_mode_loop+0x55/0x100 do_syscall_64+0x205/0x2c0 entry_SYSCALL_64_after_hwframe+0x4b/0x53 Chao further identified [2] a reproducible scenarios involving signal delivery: a non-AMX task is preempted by an AMX-enabled task which modifies the XFD MSR. When the non-AMX task resumes and reloads XSTATE with init values, a warning is triggered due to a mismatch between fpstate::xfd and the CPU's current XFD state. fpu__clear_user_states() does not currently re-synchronize the XFD state after such preemption. Invoke xfd_update_state() which detects and corrects the mismatch if the dynamic feature is enabled. This also benefits the sigreturn path, as fpu__restore_sig() may call fpu__clear_user_states() when the sigframe is inaccessible.

[PATCH v2] PCI: xilinx-xdma: Enable INTx interrupts

by Ravi Kumar Bandi

The pcie-xilinx-dma-pl driver does not enable INTx interrupts after initializing the port, preventing INTx interrupts from PCIe endpoints from flowing through the Xilinx XDMA root port bridge. This issue affects kernel 6.6.0 and later versions. This patch allows INTx interrupts generated by PCIe endpoints to flow through the root port. Tested the fix on a board with two endpoints generating INTx interrupts. Interrupts are properly detected and serviced. The /proc/interrupts output shows: [...] 32: 320 0 pl_dma:RC-Event 16 Level 400000000.axi-pcie, azdrv 52: 470 0 pl_dma:RC-Event 16 Level 500000000.axi-pcie, azdrv [...] Changes since v1:: - Fixed commit message per reviewer's comments Fixes: 8d786149d78c ("PCI: xilinx-xdma: Add Xilinx XDMA Root Port driver") Cc: stable(a)vger.kernel.org Signed-off-by: Ravi Kumar Bandi <ravib(a)amazon.com> --- drivers/pci/controller/pcie-xilinx-dma-pl.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/drivers/pci/controller/pcie-xilinx-dma-pl.c b/drivers/pci/controller/pcie-xilinx-dma-pl.c index b037c8f315e4..cc539292d10a 100644 --- a/drivers/pci/controller/pcie-xilinx-dma-pl.c +++ b/drivers/pci/controller/pcie-xilinx-dma-pl.c @@ -659,6 +659,12 @@ static int xilinx_pl_dma_pcie_setup_irq(struct pl_dma_pcie *port) return err; } + /* Enable interrupts */ + pcie_write(port, XILINX_PCIE_DMA_IMR_ALL_MASK, + XILINX_PCIE_DMA_REG_IMR); + pcie_write(port, XILINX_PCIE_DMA_IDRN_MASK, + XILINX_PCIE_DMA_REG_IDRN_MASK); + return 0; } -- 2.47.3

[PATCH 0/2] drm/xe: Fix some rebar issues

by Lucas De Marchi

Our implementation for BAR2 (lmembar) resize works at the xe_vram layer and only releases that BAR before resizing. That is not always sufficient. If the parent bridge needs to move, the BAR0 also needs to be released, otherwise the resize fails. This is the case of not having enough space allocated from the beginning. Also, there's a BAR0 in the upstream port of the pcie switch in BMG preventing the resize to propagate to the bridge as previously discussed in https://lore.kernel.org/intel-xe/20250721173057.867829-1-uwu@icenowy.me/ and https://lore.kernel.org/intel-xe/wqukxnxni2dbpdhri3cbvlrzsefgdanesgskzmxi5s… I'm bringing that commit from Ilpo here so this can be tested with the xe changes and propagate to stable. Note that the use of a pci fixup is not ideal, but without intrusive changes on resource fitting it's possibly the best alternative. I also have confirmation from HW folks that the BAR in the upstream port has no production use. I have more cleanups on top on the xe side, but those conflict with some refactors Ilpo is working on as prep for the resource fitting, so I will wait things settle to submit again. I propose to take this through the drm tree. With this I could resize the lmembar on some problematic hosts and after doing an SBR, with one caveat: the audio device also prevents the BAR from moving and it needs to be manually removed before resizing. With the PCI refactors and BAR fitting logic that Ilpo is working on, it's expected that it won't be needed for a long time.

[REGRESSION] 6.16 fae58d0155 prevents boot of google-tomato (mt8195)

by ninelore

Hi, starting with the bisected commit fae58d0155a979a8c414bbc12db09dd4b2f910d0 ("[v2] drm/mediatek: Fix device/node reference count leaks in mtk_drm_get_all_drm_priv") on 6.16.y my chromebook codenamed google-tomato with the SoC MT8195 seems to hang while initializing drm. Kernel messages over serial show CPU stalls some minutes later. I am attaching the full kernel logs below. This issue is present in 6.16.7, however not in v6.17-rc6 This is my first time reporting a bug here. Please let me know if you need additional information.

[PATCH v2 RESEND] net/dccp: validate Reset/Close/CloseReq in DCCP_REQUESTING

by Yizhou Zhao

DCCP sockets in DCCP_REQUESTING state do not check the sequence number or acknowledgment number for incoming Reset, CloseReq, and Close packets. As a result, an attacker can send a spoofed Reset packet while the client is in the requesting state. The client will accept the packet without verification and immediately close the connection, causing a denial of service (DoS) attack. This patch moves the processing of Reset, Close, and CloseReq packets into dccp_rcv_request_sent_state_process() and validates the ack number before accepting them. This fix should apply to stable versions *only* in Linux 5.x and 6.x. Note that DCCP was removed in Linux 6.16, so this patch is only relevant for older versions. We tested it on Ubuntu 24.04 LTS (Linux 6.8) and it worked as expected.

[PATCH V2] LoongArch: Align ACPI structures if ARCH_STRICT_ALIGN enabled

by Huacai Chen

ARCH_STRICT_ALIGN is used for hardware without UAL, now it only control the -mstrict-align flag. However, ACPI structures are packed by default so will cause unaligned accesses. To avoid this, define ACPI_MISALIGNMENT_NOT_SUPPORTED in asm/acenv.h to align ACPI structures if ARCH_STRICT_ALIGN enabled.
