+Subject: [PATCH] KVM: x86/mmu: Fix an sign-extension bug with mmu_seq that
+ hangs vCPUs
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Upstream commit ba6e3fe25543 ("KVM: x86/mmu: Grab mmu_invalidate_seq in
+kvm_faultin_pfn()") unknowingly fixed the bug in v6.3 when refactoring
+how KVM tracks the sequence counter snapshot.
+
+Take the vCPU's mmu_seq snapshot as an "unsigned long" instead of an "int"
+when checking to see if a page fault is stale, as the sequence count is
+stored as an "unsigned long" everywhere else in KVM. This fixes a bug
+where KVM will effectively hang vCPUs due to always thinking page faults
+are stale, which results in KVM refusing to "fix" faults.
+
+mmu_invalidate_seq (née mmu_notifier_seq) is a sequence counter used when
+KVM is handling page faults to detect if userspace mappings relevant to
+the guest were invalidated between snapshotting the counter and acquiring
+mmu_lock, i.e. to ensure that the userspace mapping KVM is using to
+resolve the page fault is fresh. If KVM sees that the counter has
+changed, KVM simply resumes the guest without fixing the fault.
+
+What _should_ happen is that the source of the mmu_notifier invalidations
+eventually goes away, mmu_invalidate_seq becomes stable, and KVM can once
+again fix guest page fault(s).
+
+But for a long-lived VM and/or a VM that the host just doesn't particularly
+like, it's possible for a VM to be on the receiving end of 2 billion (with
+a B) mmu_notifier invalidations. When that happens, bit 31 will be set in
+mmu_invalidate_seq. This causes the value to be turned into a 32-bit
+negative value when implicitly cast to an "int" by is_page_fault_stale(),
+and then sign-extended into a 64-bit unsigned when the signed "int" is
+implicitly cast back to an "unsigned long" on the call to
+mmu_invalidate_retry_hva().
+
+As a result of the casting and sign-extension, given a sequence counter of
+e.g. 0x8002dc25, mmu_invalidate_retry_hva() ends up doing
+
+ if (0x8002dc25 != 0xffffffff8002dc25)
+
+and signals that the page fault is stale and needs to be retried even
+though the sequence counter is stable, and KVM effectively hangs any vCPU
+that takes a page fault (EPT violation or #NPF when TDP is enabled).

- single-ported PCIe devices
-
-While duplicate IDs are still very harmful, including the potential to easily
-see changing devices in /dev/disk/by-id, it turn out they are extremely
-common for cheap end user NVMe devices.
-
-Relax our check for them for so that it doesn't reject the probe on
-single-ported PCIe devices, but prints a big warning instead. In doubt
-we'd still like to see quirk entries to disable the potential for
-changing supposed stable device identifier links, but this will at least
-allow users how have two (or more) of these devices to use them without
-having to manually add a new PCI ID entry with the quirk through sysfs or
-by patching the kernel.

-Subject: [PATCH] igc: Fix Kernel Panic during ndo_tx_timeout callback
-
-The Xeon validation group has been carrying out some loaded tests
-with various HW configurations, and they have seen some transmit
-queue time out happening during the test. This will cause the
-reset adapter function to be called by igc_tx_timeout().
-Similar race conditions may arise when the interface is being brought
-down and up in igc_reinit_locked(), an interrupt being generated, and
-igc_clean_tx_irq() being called to complete the TX.
-
-When the igc_tx_timeout() function is invoked, this patch will turn
-off all TX ring HW queues during igc_down() process. TX ring HW queues
-will be activated again during the igc_configure_tx_ring() process
-when performing the igc_up() procedure later.
-
-This patch also moved existing igc_disable_tx_ring_hw() to avoid using
-forward declaration.

-Subject: [PATCH] mm: suppress mm fault logging if fatal signal already pending
-
-Commit eda0047296a1 ("mm: make the page fault mmap locking killable")
-intentionally made it much easier to trigger the "page fault fails
-because a fatal signal is pending" situation, by having the mmap locking
-fail early in that case.
-
-We have long aborted page faults in other fatal cases when the actual IO
-for a page is interrupted by SIGKILL - which is particularly useful for
-the traditional case of NFS hanging due to network issues, but local
-filesystems could cause it too if you happened to get the SIGKILL while
-waiting for a page to be faulted in (eg lock_folio_maybe_drop_mmap()).
-
-So aborting the page fault wasn't a new condition - but it now triggers
-earlier, before we even get to 'handle_mm_fault()'. And as a result the
-error doesn't go through our 'fault_signal_pending()' logic, and doesn't
-get filtered away there.
-
-Normally you'd never even notice, because if a fatal signal is pending,
-the new SIGSEGV we send ends up being ignored anyway.
-
-But it turns out that there is one very noticeable exception: if you
-enable 'show_unhandled_signals', the aborted page fault will be logged
-in the kernel messages, and you'll get a scary line looking something
-like this in your logs:
-
- pverados[2183248]: segfault at 55e5a00f9ae0 ip 000055e5a00f9ae0 sp 00007ffc0720bea8 error 14 in perl[55e5a00d4000+195000] likely on CPU 10 (core 4, socket 0)
-
-which is rather misleading. It's not really a segfault at all, it's
-just "the thread was killed before the page fault completed, so we
-aborted the page fault".
-
-Fix this by just making it clear that a pending fatal signal means that
-any new signal coming in after that is implicitly handled. This will
-avoid the misleading logging, since now the signal isn't 'unhandled' any
-more.

+Subject: [PATCH] net: thunderbolt: Fix TCPv6 GSO checksum calculation
+
+Alex reported that running ssh over IPv6 does not work with
+Thunderbolt/USB4 networking driver. The reason for that is that driver
+should call skb_is_gso() before calling skb_is_gso_v6(), and it should
+not return false after calculates the checksum successfully. This probably
+was a copy paste error from the original driver where it was done properly.

-Subject: [PATCH] KVM: x86/mmu: Fix an sign-extension bug with mmu_seq that
- hangs vCPUs
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Upstream commit ba6e3fe25543 ("KVM: x86/mmu: Grab mmu_invalidate_seq in
-kvm_faultin_pfn()") unknowingly fixed the bug in v6.3 when refactoring
-how KVM tracks the sequence counter snapshot.
-
-Take the vCPU's mmu_seq snapshot as an "unsigned long" instead of an "int"
-when checking to see if a page fault is stale, as the sequence count is
-stored as an "unsigned long" everywhere else in KVM. This fixes a bug
-where KVM will effectively hang vCPUs due to always thinking page faults
-are stale, which results in KVM refusing to "fix" faults.
-
-mmu_invalidate_seq (née mmu_notifier_seq) is a sequence counter used when
-KVM is handling page faults to detect if userspace mappings relevant to
-the guest were invalidated between snapshotting the counter and acquiring
-mmu_lock, i.e. to ensure that the userspace mapping KVM is using to
-resolve the page fault is fresh. If KVM sees that the counter has
-changed, KVM simply resumes the guest without fixing the fault.
-
-What _should_ happen is that the source of the mmu_notifier invalidations
-eventually goes away, mmu_invalidate_seq becomes stable, and KVM can once
-again fix guest page fault(s).
-
-But for a long-lived VM and/or a VM that the host just doesn't particularly
-like, it's possible for a VM to be on the receiving end of 2 billion (with
-a B) mmu_notifier invalidations. When that happens, bit 31 will be set in
-mmu_invalidate_seq. This causes the value to be turned into a 32-bit
-negative value when implicitly cast to an "int" by is_page_fault_stale(),
-and then sign-extended into a 64-bit unsigned when the signed "int" is
-implicitly cast back to an "unsigned long" on the call to
-mmu_invalidate_retry_hva().
-
-As a result of the casting and sign-extension, given a sequence counter of
-e.g. 0x8002dc25, mmu_invalidate_retry_hva() ends up doing
-
- if (0x8002dc25 != 0xffffffff8002dc25)
-
-and signals that the page fault is stale and needs to be retried even
-though the sequence counter is stable, and KVM effectively hangs any vCPU
-that takes a page fault (EPT violation or #NPF when TDP is enabled).

+Subject: [PATCH] thunderbolt: Restart XDomain discovery handshake after
+ failure
+
+Alex reported that after rebooting the other host the peer-to-peer link
+does not come up anymore. The reason for this is that the host that was
+not rebooted tries to send the UUID request only 10 times according to
+the USB4 Inter-Domain spec and gives up if it does not get reply. Then
+when the other side is actually ready it cannot get the link established
+anymore. The USB4 Inter-Domain spec requires that the discovery protocol
+is restarted in that case so implement this now.

-Subject: [PATCH] net: thunderbolt: Fix TCPv6 GSO checksum calculation
-
-Alex reported that running ssh over IPv6 does not work with
-Thunderbolt/USB4 networking driver. The reason for that is that driver
-should call skb_is_gso() before calling skb_is_gso_v6(), and it should
-not return false after calculates the checksum successfully. This probably
-was a copy paste error from the original driver where it was done properly.

-Subject: [PATCH] thunderbolt: Restart XDomain discovery handshake after
- failure
-
-Alex reported that after rebooting the other host the peer-to-peer link
-does not come up anymore. The reason for this is that the host that was
-not rebooted tries to send the UUID request only 10 times according to
-the USB4 Inter-Domain spec and gives up if it does not get reply. Then
-when the other side is actually ready it cannot get the link established
-anymore. The USB4 Inter-Domain spec requires that the discovery protocol
-is restarted in that case so implement this now.

-Subject: [PATCH] x86/fpu: Set X86_FEATURE_OSXSAVE feature after enabling
- OSXSAVE in CR4
-
-0-Day found a 34.6% regression in stress-ng's 'af-alg' test case, and
-bisected it to commit b81fac906a8f ("x86/fpu: Move FPU initialization into
-arch_cpu_finalize_init()"), which optimizes the FPU init order, and moves
-the CR4_OSXSAVE enabling into a later place:
-
- arch_cpu_finalize_init
- identify_boot_cpu
- identify_cpu
- generic_identify
- get_cpu_cap --> setup cpu capability
- ...
- fpu__init_cpu
- fpu__init_cpu_xstate
- cr4_set_bits(X86_CR4_OSXSAVE);
-
-As the FPU is not yet initialized the CPU capability setup fails to set
-X86_FEATURE_OSXSAVE. Many security module like 'camellia_aesni_avx_x86_64'
-depend on this feature and therefore fail to load, causing the regression.
-
-Cure this by setting X86_FEATURE_OSXSAVE feature right after OSXSAVE
-enabling.
-
-[ tglx: Moved it into the actual BSP FPU initialization code and added a comment ]
-
-Fixes: b81fac906a8f ("x86/fpu: Move FPU initialization into arch_cpu_finalize_init()")

-Subject: [PATCH] thunderbolt: Mask ring interrupt on Intel hardware as well
-
-When resuming from system sleep states the driver issues following
-warning on Intel hardware:
-
- thunderbolt 0000:07:00.0: interrupt for TX ring 0 is already enabled
-
-The reason for this is that the commit in question did not mask the ring
-interrupt on Intel hardware leaving the interrupt active. Fix this by
-masking it also in Intel hardware.
