drm/amd: Disallow s0ix without BIOS support again

commit cf488dcd0ab7 ("drm/amd: Allow s0ix without BIOS support") showed
improvements to power consumption over suspend when s0ix wasn't enabled in
BIOS and the system didn't support S3.

This patch however was misguided because the reason the system didn't
support S3 was because SMT was disabled in OEM BIOS setup.
This prevented the BIOS from allowing S3.

Also allowing GPUs to use the s2idle path actually causes problems if
they're invoked on systems that may not support s2idle in the platform
firmware. `systemd` has a tendency to try to use `s2idle` if `deep` fails
for any reason, which could lead to unexpected flows.

The original commit also fixed a problem during resume from suspend to idle
without hardware support, but this is no longer necessary with commit
ca4751866397 ("drm/amd: Don't allow s0ix on APUs older than Raven")

Revert commit cf488dcd0ab7 ("drm/amd: Allow s0ix without BIOS support")
to make it match the expected behavior again.

KVM: x86: Bail from kvm_recalculate_phys_map() if x2APIC ID is out-of-bounds

Bail from kvm_recalculate_phys_map() and disable the optimized map if the
target vCPU's x2APIC ID is out-of-bounds, i.e. if the vCPU was added
and/or enabled its local APIC after the map was allocated.  This fixes an
out-of-bounds access bug in the !x2apic_format path where KVM would write
beyond the end of phys_map.

Check the x2APIC ID regardless of whether or not x2APIC is enabled,
as KVM's hardcodes x2APIC ID to be the vCPU ID, i.e. it can't change, and
the map allocation in kvm_recalculate_apic_map() doesn't check for x2APIC
being enabled, i.e. the check won't get false postivies.

Note, this also affects the x2apic_format path, which previously just
ignored the "x2apic_id > new->max_apic_id" case.  That too is arguably a
bug fix, as ignoring the vCPU meant that KVM would not send interrupts to
the vCPU until the next map recalculation.  In practice, that "bug" is
likely benign as a newly present vCPU/APIC would immediately trigger a
recalc.  But, there's no functional downside to disabling the map, and
a future patch will gracefully handle the -E2BIG case by retrying instead
of simply disabling the optimized map.

Opportunistically add a sanity check on the xAPIC ID size, along with a
comment explaining why the xAPIC ID is guaranteed to be "good".

17 months agoKVM: SVM: vNMI pending bit is V_NMI_PENDING_MASK not V_NMI_BLOCKING_MASK

KVM: SVM: vNMI pending bit is V_NMI_PENDING_MASK not V_NMI_BLOCKING_MASK

While testing Hyper-V enabled Windows Server 2019 guests on Zen4 hardware
I noticed that with vCPU count large enough (> 16) they sometimes froze at
boot.
With vCPU count of 64 they never booted successfully - suggesting some kind
of a race condition.

Since adding "vnmi=0" module parameter made these guests boot successfully
it was clear that the problem is most likely (v)NMI-related.

Running kvm-unit-tests quickly showed failing NMI-related tests cases, like
"multiple nmi" and "pending nmi" from apic-split, x2apic and xapic tests
and the NMI parts of eventinj test.

The issue was that once one NMI was being serviced no other NMI was allowed
to be set pending (NMI limit = 0), which was traced to
svm_is_vnmi_pending() wrongly testing for the "NMI blocked" flag rather
than for the "NMI pending" flag.

Fix this by testing for the right flag in svm_is_vnmi_pending().
Once this is done, the NMI-related kvm-unit-tests pass successfully and
the Windows guest no longer freezes at boot.

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).

Revert "ext4: remove ac->ac_found > sbi->s_mb_min_to_scan dead check in ext4_mb_check_limits"

This reverts commit 32c0869370194ae5ac9f9f501953ef693040f6a1.

The reverted commit was intended to remove a dead check however it was observed
that this check was actually being used to exit early instead of looping
sbi->s_mb_max_to_scan times when we are able to find a free extent bigger than
the goal extent. Due to this, a my performance tests (fsmark, parallel file
writes in a highly fragmented FS) were seeing a 2x-3x regression.

Example, the default value of the following variables is:

sbi->s_mb_max_to_scan = 200
sbi->s_mb_min_to_scan = 10

In ext4_mb_check_limits() if we find an extent smaller than goal, then we return
early and try again. This loop will go on until we have processed
sbi->s_mb_max_to_scan(=200) number of free extents at which point we exit and
just use whatever we have even if it is smaller than goal extent.

Now, the regression comes when we find an extent bigger than goal. Earlier, in
this case we would loop only sbi->s_mb_min_to_scan(=10) times and then just use
the bigger extent. However with commit 32c08693 that check was removed and hence
we would loop sbi->s_mb_max_to_scan(=200) times even though we have a big enough
free extent to satisfy the request. The only time we would exit early would be
when the free extent is *exactly* the size of our goal, which is pretty uncommon
occurrence and so we would almost always end up looping 200 times.

Hence, revert the commit by adding the check back to fix the regression. Also
add a comment to outline this policy.

media: uvcvideo: Don't expose unsupported formats to userspace

the fcc field set to 0. Since commit 50459f103edf ("media: uvcvideo:

provide the format description string, which the V4L2 core can't do
without a valid 4CC. This triggers a WARN_ON.

As a format with a zero 4CC can't be selected, it is unusable for

instance, which fixes the warning.

17 months agofork, vhost: Use CLONE_THREAD to fix freezer/ps regression
Mike Christie [Thu, 1 Jun 2023 18:32:32 +0000 (13:32 -0500)]
fork, vhost: Use CLONE_THREAD to fix freezer/ps regression

When switching from kthreads to vhost_tasks two bugs were added:
1. The vhost worker tasks's now show up as processes so scripts doing
ps or ps a would not incorrectly detect the vhost task as another
process.  2. kthreads disabled freeze by setting PF_NOFREEZE, but
vhost tasks's didn't disable or add support for them.

To fix both bugs, this switches the vhost task to be thread in the
process that does the VHOST_SET_OWNER ioctl, and has vhost_worker call
get_signal to support SIGKILL/SIGSTOP and freeze signals. Note that
SIGKILL/STOP support is required because CLONE_THREAD requires
CLONE_SIGHAND which requires those 2 signals to be supported.

This is a modified version of the patch written by Mike Christie
<michael.christie@oracle.com> which was a modified version of patch
originally written by Linus.

Much of what depended upon PF_IO_WORKER now depends on PF_USER_WORKER.
Including ignoring signals, setting up the register state, and having
get_signal return instead of calling do_group_exit.

Tidied up the vhost_task abstraction so that the definition of
vhost_task only needs to be visible inside of vhost_task.c.  Making
it easier to review the code and tell what needs to be done where.
As part of this the main loop has been moved from vhost_worker into
vhost_task_fn.  vhost_worker now returns true if work was done.

The main loop has been updated to call get_signal which handles
SIGSTOP, freezing, and collects the message that tells the thread to
exit as part of process exit.  This collection clears
__fatal_signal_pending.  This collection is not guaranteed to
clear signal_pending() so clear that explicitly so the schedule()
sleeps.

For now the vhost thread continues to exist and run work until the
last file descriptor is closed and the release function is called as
part of freeing struct file.  To avoid hangs in the coredump
rendezvous and when killing threads in a multi-threaded exec.  The
coredump code and de_thread have been modified to ignore vhost threads.

Remvoing the special case for exec appears to require teaching
vhost_dev_flush how to directly complete transactions in case
the vhost thread is no longer running.

Removing the special case for coredump rendezvous requires either the
above fix needed for exec or moving the coredump rendezvous into
get_signal.

selinux: don't use make's grouped targets feature yet

The Linux Kernel currently only requires make v3.82 while the grouped
target functionality requires make v4.3.  Removed the grouped target
introduced in 4ce1f694eb5d ("selinux: ensure av_permissions.h is
built when needed") as well as the multiple header file targets in

mptcp: fix connect timeout handling

Ondrej reported a functional issue WRT timeout handling on connect

The problem is that the current mptcp connect waits for both the
MPTCP socket level timeout, and the first subflow socket timeout.
The latter is not influenced/touched by the exposed setsockopt().

Overall the above makes the SO_SNDTIMEO a no-op on connect.

Since mptcp_connect is invoked via inet_stream_connect and the
latter properly handle the MPTCP level timeout, we can address the
issue making the nested subflow level connect always unblocking.

This also allow simplifying a bit the code, dropping an ugly hack
to handle the fastopen and custom proto_ops connect.

[CAUSE]
Dev-replace reuses scrub code to iterate all extents and write the
existing content back to the new device.

And for zoned devices, we call fill_writer_pointer_gap() to make sure
all the writes into the zoned device is sequential, even if there may be
some gaps between the writes.

However we have several different bugs all related to zoned dev-replace:

- We are using ZONE_APPEND operation for metadata style write back
  For zoned devices, btrfs has two ways to write data:

  * ZONE_APPEND for data
    This allows higher queue depth, but will not be able to know where
    the write would land.
    Thus needs to grab the real on-disk physical location in it's endio.

  * WRITE for metadata
    This requires single queue depth (new writes can only be submitted
    after previous one finished), and all writes must be sequential.

  For scrub, we go single queue depth, but still goes with ZONE_APPEND,
  which requires btrfs_bio::inode being populated.
  This is the cause of that crash.

- No correct tracing of write_pointer
  After a write finished, we should forward sctx->write_pointer, or
  fill_writer_pointer_gap() would not work properly and cause more
  than necessary zero out, and fill the whole zone prematurely.

- Incorrect physical bytenr passed to fill_writer_pointer_gap()
  In scrub_write_sectors(), one call site passes logical address, which
  is completely wrong.

  The other call site passes physical address of current sector, but
  we should pass the physical address of the btrfs_bio we're submitting.

  This is the cause of the -EIO errors.

[FIX]
- Do not use ZONE_APPEND for btrfs_submit_repair_write().

- Manually forward sctx->write_pointer after successful writeback

- Use the physical address of the to-be-submitted btrfs_bio for
  fill_writer_pointer_gap()

Now zoned device replace would work as expected.
