Subject: [PATCH] kvm: xsave set: mask-out PKRU bit in xfeatures if vCPU has no
|
||||
support
|
||||
MIME-Version: 1.0
|
||||
Content-Type: text/plain; charset=UTF-8
|
||||
Content-Transfer-Encoding: 8bit
|
||||
|
||||
Fixes live-migrations & snapshot-rollback of VMs with a restricted
|
||||
CPU type (e.g., qemu64) from our 5.15 based kernel (default Proxmox
|
||||
VE 7.4) to the 6.2 (and future newer) of Proxmox VE 8.0.
|
||||
|
||||
Previous to ad856280ddea ("x86/kvm/fpu: Limit guest user_xfeatures to
|
||||
supported bits of XCR0") the PKRU bit of the host could leak into the
|
||||
state from the guest, which caused trouble when migrating between
|
||||
hosts with different CPUs, i.e., where the source supported it but
|
||||
the target did not, causing a general protection fault when the guest
|
||||
tried to use a pkru related instruction after the migration.
|
||||
|
||||
But the fix, while welcome, caused a temporary out-of-sync state when
|
||||
migrating such a VM from a kernel without the fix to a kernel with
|
||||
the fix, as it threw of KVM when the CPUID of the guest and most of
|
||||
the state doesn't report XSAVE and thus any xfeatures, but PKRU and
|
||||
the related state is set as enabled, causing the vCPU to spin at 100%
|
||||
without any progress forever.
|
||||
|
||||
The fix could be at two sites, either in QEMU or in the kernel, I
|
||||
choose the kernel as we have all the info there for a targeted
|
||||
heuristic so that we don't have to adapt QEMU and qemu-server, the
|
||||
latter even on both sides.
|
||||
|
||||
Still, a short summary of the possible fixes and short drawbacks:
|
||||
* on QEMU-side either
|
||||
- clear the PKRU state in the migration saved state would be rather
|
||||
complicated to implement as the vCPU is initialised way before we
|
||||
have the saved xfeature state available to check what we'd need
|
||||
to do, plus the user-space only gets a memory blob from ioctl
|
||||
KVM_GET_XSAVE2 that it passes to KVM_SET_XSAVE ioctl, there are
|
||||
no ABI guarantees, and while the struct seem stable for 5.15 to
|
||||
6.5-rc1, that doesn't has to be for future kernels, so off the
|
||||
table.
|
||||
- enforce that the CPUID reports PKU support even if it normally
|
||||
wouldn't. While this works (tested by hard-coding it as POC) it
|
||||
is a) not really nice and b) needs some interaction from
|
||||
qemu-server to enable this flag as otherwise we have no good info
|
||||
to decide when it's OK to do this, which means we need to adapt
|
||||
both PVE 7 and 8's qemu-server and also pve-qemu, workable but
|
||||
not optimal
|
||||
|
||||
* on Kernel/KVM-side we can hook into the set XSAVE ioctl specific to
|
||||
the KVM subsystem, which already reduces chance of regression for
|
||||
all other places. There we have access to the union/struct
|
||||
definitions of the saved state and thus can savely cast to that.
|
||||
We also got access to the vCPU's CPUID capabilities, meaning we can
|
||||
check if the XCR0 (first XSAVE Control Register) reports
|
||||
that it support the PKRU feature, and if it does *NOT* but the
|
||||
saved xfeatures register from XSAVE *DOES* report it, we can safely
|
||||
assume that this combination is due to an migration from an older,
|
||||
leaky kernel – and clear the bit in the xfeature register before
|
||||
restoring it to the guest vCPU KVM state, avoiding the confusing
|
||||
situation that made the vCPU spin at 100%.
|
||||
This should be safe to do, as the guest vCPU CPUID never reported
|
||||
support for the PKRU feature, and it's also a relatively niche and
|
||||
newish feature.
|
||||
|
||||
If it gains us something we can drop this patch a bit in the future
|
||||
Proxmox VE 9 major release, but we should ensure that VMs that where
|
||||
started before PVE 8 cannot be directly live-migrated to the release
|
||||
that includes that change; so we should rather only drop it if the
|
||||
maintenance burden is high.

Subject: [PATCH] KVM: x86/mmu: Grab memslot for correct address space in NX
|
||||
recovery worker
|
||||
|
||||
commit 817fa998362d6ea9fabd5e97af8e9e2eb5f0e6f2 upstream.
|
||||
|
||||
Factor in the address space (non-SMM vs. SMM) of the target shadow page
|
||||
when recovering potential NX huge pages, otherwise KVM will retrieve the
|
||||
wrong memslot when zapping shadow pages that were created for SMM. The
|
||||
bug most visibly manifests as a WARN on the memslot being non-NULL, but
|
||||
the worst case scenario is that KVM could unaccount the shadow page
|
||||
without ensuring KVM won't install a huge page, i.e. if the non-SMM slot
|
||||
is being dirty logged, but the SMM slot is not.

|

This bug was exposed by commit edbdb43fc96b ("KVM: x86: Preserve TDP MMU
|
||||
roots until they are explicitly invalidated"), which allowed KVM to retain
|
||||
SMM TDP MMU roots effectively indefinitely. Before commit edbdb43fc96b,
|
||||
KVM would zap all SMM TDP MMU roots and thus all SMM TDP MMU shadow pages
|
||||
once all vCPUs exited SMM, which made the window where this bug (recovering
|
||||
an SMM NX huge page) could be encountered quite tiny. To hit the bug, the
|
||||
NX recovery thread would have to run while at least one vCPU was in SMM.
|
||||
Most VMs typically only use SMM during boot, and so the problematic shadow
|
||||
pages were gone by the time the NX recovery thread ran.
|
||||
|
||||
Now that KVM preserves TDP MMU roots until they are explicitly invalidated
|
||||
(e.g. by a memslot deletion), the window to trigger the bug is effectively
|
||||
never closed because most VMMs don't delete memslots after boot (except
|
||||
for a handful of special scenarios).

Subject: [PATCH] nvme: don't reject probe due to duplicate IDs for
|
||||
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.
