[PATCH 1/2] PCI/MSI: Add MSIX option to write to ENTRY_DATA before any reads

by dullfire＠yahoo.com

From: Jonathan Currier <dullfire(a)yahoo.com> Commit 7d5ec3d36123 ("PCI/MSI: Mask all unused MSI-X entries") introduces a readl() from ENTRY_VECTOR_CTRL before the writel() to ENTRY_DATA. This is correct, however some hardware, like the Sun Neptune chips, the niu module, will cause an error and/or fatal trap if any MSIX table entry is read before the corresponding ENTRY_DATA field is written to. This patch adds an optional early writel() in msix_prepare_msi_desc().

[PATCH] usb: gadget: f_midi: Fixing wMaxPacketSize exceeded issue during MIDI bind retries

by Selvarasu Ganesan

The current implementation sets the wMaxPacketSize of bulk in/out endpoints to 1024 bytes at the end of the f_midi_bind function. However, in cases where there is a failure in the first midi bind attempt, consider rebinding. This scenario may encounter an f_midi_bind issue due to the previous bind setting the bulk endpoint's wMaxPacketSize to 1024 bytes, which exceeds the ep->maxpacket_limit where configured TX/RX FIFO's maxpacket size of 512 bytes for IN/OUT endpoints in support HS speed only. This commit addresses this issue by resetting the wMaxPacketSize before endpoint claim.

[PATCH 6.6] KVM: x86: Make x2APIC ID 100% readonly

by Gavin Guo

From: Sean Christopherson <seanjc(a)google.com> [ Upstream commit 4b7c3f6d04bd53f2e5b228b6821fb8f5d1ba3071 ] Ignore the userspace provided x2APIC ID when fixing up APIC state for KVM_SET_LAPIC, i.e. make the x2APIC fully readonly in KVM. Commit a92e2543d6a8 ("KVM: x86: use hardware-compatible format for APIC ID register"), which added the fixup, didn't intend to allow userspace to modify the x2APIC ID. In fact, that commit is when KVM first started treating the x2APIC ID as readonly, apparently to fix some race: static inline u32 kvm_apic_id(struct kvm_lapic *apic) { - return (kvm_lapic_get_reg(apic, APIC_ID) >> 24) & 0xff; + /* To avoid a race between apic_base and following APIC_ID update when + * switching to x2apic_mode, the x2apic mode returns initial x2apic id. + */ + if (apic_x2apic_mode(apic)) + return apic->vcpu->vcpu_id; + + return kvm_lapic_get_reg(apic, APIC_ID) >> 24; } Furthermore, KVM doesn't support delivering interrupts to vCPUs with a modified x2APIC ID, but KVM *does* return the modified value on a guest RDMSR and for KVM_GET_LAPIC. I.e. no remotely sane setup can actually work with a modified x2APIC ID. Making the x2APIC ID fully readonly fixes a WARN in KVM's optimized map calculation, which expects the LDR to align with the x2APIC ID.

[REGRESSION] Distorted sound on Acer Aspire A115-31 laptop

by Evgeny Kapun

I am using an Acer Aspire A115-31 laptop. When running newer kernel versions, sound played through headphones is distorted, but when running older versions, it is not. Kernel version: Linux version 6.12.5 (user@hostname) (gcc (Debian 14.2.0-8) 14.2.0, GNU ld (GNU Binutils for Debian) 2.43.50.20241210) #1 SMP PREEMPT_DYNAMIC Sun Dec 15 05:09:16 IST 2024 Operating System: Debian GNU/Linux trixie/sid No special actions are needed to reproduce the issue. The sound is distorted all the time, and it doesn't depend on anything besides using an affected kernel version. It seems to be caused by commit 34ab5bbc6e82214d7f7393eba26d164b303ebb4e (ALSA: hda/realtek - Add Headset Mic supported Acer NB platform). Indeed, if I remove the entry that this commit adds, the issue disappears. lspci output for the device in question: 00:0e.0 Multimedia audio controller [0401]: Intel Corporation Celeron/Pentium Silver Processor High Definition Audio [8086:3198] (rev 06) Subsystem: Acer Incorporated [ALI] Device [1025:1360] Flags: bus master, fast devsel, latency 0, IRQ 130 Memory at a1214000 (64-bit, non-prefetchable) [size=16K] Memory at a1000000 (64-bit, non-prefetchable) [size=1M] Capabilities: [50] Power Management version 3 Capabilities: [80] Vendor Specific Information: Len=14 <?> Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+ Capabilities: [70] Express Root Complex Integrated Endpoint, IntMsgNum 0 Kernel driver in use: snd_hda_intel Kernel modules: snd_hda_intel, snd_soc_avs, snd_sof_pci_intel_apl

[PATCH v2 7/7] ima: Reset IMA_NONACTION_RULE_FLAGS after post_setattr

by Roberto Sassu

From: Roberto Sassu <roberto.sassu(a)huawei.com> Commit 11c60f23ed13 ("integrity: Remove unused macro IMA_ACTION_RULE_FLAGS") removed the IMA_ACTION_RULE_FLAGS mask, due to it not being used after commit 0d73a55208e9 ("ima: re-introduce own integrity cache lock"). However, it seems that the latter commit mistakenly used the wrong mask when moving the code from ima_inode_post_setattr() to process_measurement(). There is no mention in the commit message about this change and it looks quite important, since changing from IMA_ACTIONS_FLAGS (later renamed to IMA_NONACTION_FLAGS) to IMA_ACTION_RULE_FLAGS was done by commit 42a4c603198f0 ("ima: fix ima_inode_post_setattr"). Restore the original change, but with new mask 0xfb000000 since the policy-specific flags changed meanwhile, and rename IMA_ACTION_RULE_FLAGS to IMA_NONACTION_RULE_FLAGS, to be consistent with IMA_NONACTION_FLAGS.

[PATCH v2 6/7] ima: Discard files opened with O_PATH

by Roberto Sassu

From: Roberto Sassu <roberto.sassu(a)huawei.com> According to man open.2, files opened with O_PATH are not really opened. The obtained file descriptor is used to indicate a location in the filesystem tree and to perform operations that act purely at the file descriptor level. Thus, ignore open() syscalls with O_PATH, since IMA cares about file data. Cc: stable(a)vger.kernel.org # v2.6.39.x Fixes: 1abf0c718f15a ("New kind of open files - "location only".")
