[PATCH 1/1] PCI/bwctrl: Disable PCIe BW controller during reset

by Ilpo Järvinen

PCIe BW controller enables BW notifications for Downstream Ports by setting Link Bandwidth Management Interrupt Enable (LBMIE) and Link Autonomous Bandwidth Interrupt Enable (LABIE) (PCIe Spec. r6.2 sec. 7.5.3.7). It was discovered that performing a reset can lead to the device underneath the Downstream Port becoming unavailable if BW notifications are left enabled throughout the reset sequence (at least LBMIE was found to cause an issue). While the PCIe Specifications do not indicate BW notifications could not be kept enabled during resets, the PCIe Link state during an intentional reset is not of large interest. Thus, disable BW controller for the bridge while reset is performed and re-enable it after the reset has completed to workaround the problems some devices encounter if BW notifications are left on throughout the reset sequence. Keep a counter for the disable/enable because MFD will execute pci_dev_save_and_disable() and pci_dev_restore() back to back for sibling devices: [ 50.139010] vfio-pci 0000:01:00.0: resetting [ 50.139053] vfio-pci 0000:01:00.1: resetting [ 50.141126] pcieport 0000:00:01.1: PME: Spurious native interrupt!

Resets shouldn't cause devices to become unavailable just because BW notifications have been enabled. Before somebody comments on those dual rwsems, I do have yet to be submitted patch to simplify the locking as per Lukas Wunner's earlier suggestion.

[PATCH] drm/ttm/tests: fix potential null pointer dereference in ttm_bo_unreserve_bulk()

by Qasim Ijaz

In the ttm_bo_unreserve_bulk() test function, resv is allocated using kunit_kzalloc(), but the subsequent assertion mistakenly verifies the ttm_dev pointer instead of checking the resv pointer. This mistake means that if allocation for resv fails, the error will go undetected, resv will be NULL and a call to dma_resv_init(resv) will dereference a NULL pointer. Fix the assertion to properly verify the resv pointer.

[PATCH net 13/13] net: dsa: mv88e6xxx: workaround RGMII transmit delay erratum for 6320 family

by Marek Behún

Implement the workaround for erratum 3.3 RGMII timing may be out of spec when transmit delay is enabled for the 6320 family, which says: When transmit delay is enabled via Port register 1 bit 14 = 1, duty cycle may be out of spec. Under very rare conditions this may cause the attached device receive CRC errors.

[PATCH v4 0/3] leds: rgb: leds-qcom-lpg: PWM fixes

by Abel Vesa

The PWM allow configuring the PWM resolution from 8 bits PWM values up to 15 bits values, for the Hi-Res PWMs, and then either 6-bit or 9-bit for the normal PWMs. The current implementation loops through all possible resolutions (PWM sizes), for the PWM subtype, on top of the already existing process of determining the prediv, exponent and refclk. The first and second issues are related to capping the computed PWM value. The third issue is that it uses the wrong maximum possible PWM value for determining the best matched period. Fix all of them. Signed-off-by: Abel Vesa <abel.vesa(a)linaro.org> --- Changes in v4: - Rebased on next-20250305 - Re-worded the commit messages for the first two patches to include an example that should better explain what the issue that is being fixed is.

If not enough pages provided, the HV can report to the VM how much is needed so the VM can reallocate and repeat. Commit ae596615d93d ("virt: sev-guest: Reduce the scope of SNP command mutex") moved handling of the allocated/desired pages number out of scope of said mutex and create a possibility for a race (multiple instances trying to trigger Extended request in a VM) as there is just one instance of snp_msg_desc per /dev/sev-guest and no locking other than snp_cmd_mutex. Fix the issue by moving the data blob/size and the GHCB input struct (snp_req_data) into snp_guest_req which is allocated on stack now and accessed by the GHCB caller under that mutex. Stop allocating SEV_FW_BLOB_MAX_SIZE in snp_msg_alloc() as only one of four callers needs it. Free the received blob in get_ext_report() right after it is copied to the userspace. Possible future users of snp_send_guest_request() are likely to have different ideas about the buffer size anyways.

[PATCH 5.10.y] KVM: x86: Reject Hyper-V's SEND_IPI hypercalls if local APIC isn't in-kernel

by Abdelkareem Abdelsaamad

From: Sean Christopherson <seanjc(a)google.com> commit a8de7f100bb5989d9c3627d3a223ee1c863f3b69 upstream. Advertise support for Hyper-V's SEND_IPI and SEND_IPI_EX hypercalls if and only if the local API is emulated/virtualized by KVM, and explicitly reject said hypercalls if the local APIC is emulated in userspace, i.e. don't rely on userspace to opt-in to KVM_CAP_HYPERV_ENFORCE_CPUID. Rejecting SEND_IPI and SEND_IPI_EX fixes a NULL-pointer dereference if Hyper-V enlightenments are exposed to the guest without an in-kernel local APIC: dump_stack+0xbe/0xfd __kasan_report.cold+0x34/0x84 kasan_report+0x3a/0x50 __apic_accept_irq+0x3a/0x5c0 kvm_hv_send_ipi.isra.0+0x34e/0x820 kvm_hv_hypercall+0x8d9/0x9d0 kvm_emulate_hypercall+0x506/0x7e0 __vmx_handle_exit+0x283/0xb60 vmx_handle_exit+0x1d/0xd0 vcpu_enter_guest+0x16b0/0x24c0 vcpu_run+0xc0/0x550 kvm_arch_vcpu_ioctl_run+0x170/0x6d0 kvm_vcpu_ioctl+0x413/0xb20 __se_sys_ioctl+0x111/0x160 do_syscal1_64+0x30/0x40 entry_SYSCALL_64_after_hwframe+0x67/0xd1 Note, checking the sending vCPU is sufficient, as the per-VM irqchip_mode can't be modified after vCPUs are created, i.e. if one vCPU has an in-kernel local APIC, then all vCPUs have an in-kernel local APIC.

While it's not freed back to system correctly when kdump kernel is reloaded or unloaded. Then memory leak is caused. Fix it by introducing x86 specific function arch_kimage_file_post_load_cleanup(), and freeing the buffer there. And also remove the incorrect elf header buffer freeing code. Before calling arch specific kexec_file loading function, the image instance has been initialized. So 'image->elf_headers' must be NULL. It doesn't make sense to free the elf header buffer in the place. Three different people have reported three bugs about the memory leak on x86_64 inside Redhat.

[PATCH 6.1.y] fs/ntfs3: Fix shift-out-of-bounds in ntfs_fill_super

by Miguel García

From: Konstantin Komarov <almaz.alexandrovich(a)paragon-software.com> commit 91a4b1ee78cb100b19b70f077c247f211110348f upstream. This patch is a backport and fixes an UBSAN warning about shift-out-of-bounds in ntfs_fill_super() function of the NTFS3 driver. The original code incorrectly calculated MFT record size, causing undefined behavior when performing bit shifts with values that exceed type limits. The fix has been verified by executing the syzkaller reproducer test case. After applying this patch, the system successfully handles the test case without kernel panic or UBSAN warnings.
