media: atomisp: Remove isp_timeout flag

isp_timeout only ever gets set in __atomisp_css_recover() and then
immediately gets cleared again after calling atomisp_reset().

All this happens with isp->mutex held.

The only consumer of isp->isp_timeout is atomisp_stop_streaming(), which
also holds isp->mutex and which is *not* called by atomisp_reset().

Since both hold isp->mutex and since __atomisp_css_recover() clears
isp_timeout before releasing the mutex, atomisp_stop_streaming() can
never see isp_timeout being true, so just remove the flag.

media: atomisp: Replace source-pad checks with run-mode checks

Currently atomisp behavior is determined by a mix of which /dev/video# node
(which isp-subdev source-pad) is opened + which run-mode is set.
With various combinations not being allowed and likely leading to crashes
due to lack of error checking.

Now that we no longer support continuous mode and thus no longer support
streaming from 2 /dev/video# nodes at the same time, there is no need
to have a separate /dev/video# node for each run-mode. Instead the plan is
to support the 3 different run-modes on a single /dev/video# node.
Since we are moving to a single isp-subdev source-pad, the behavior should
then be solely and consistently be defined by the run-mode.

Replace various source-pad checks with run-mode checks in preparation for
moving to a single source-pad. In some places the new run-mode checks
overlap with existing run-mode checks and the checks are folded together
into a single check.

This removes handling of the ATOMISP_SUBDEV_PAD_SOURCE_VF source-pad,
this source-pad was only useful for continuous mode, for which support has
been removed.

Note that currently the only run-mode which we actually have been able to
get to work is the video-capture with scaler aka preview mode and as such
that is also the only run-mode tested. This patch is intended to preserve
the current (known to not work 100%) behavior of the other run-modes, so

media: venus: helpers: Fix ALIGN() of non power of two

ALIGN() expects its second argument to be a power of 2, otherwise
incorrect results are produced for some inputs. The output can be
both larger or smaller than what is expected.

For example, ALIGN(304, 192) equals 320 instead of 384, and
ALIGN(65, 192) equals 256 instead of 192.

However, nestling two ALIGN() as is done in this case seem to only
produce results equal to or bigger than the expected result if ALIGN()
had handled non powers of two, and that in turn results in framesizes
that are either the correct size or too large.

Fortunately, since 192 * 4 / 3 equals 256, it turns out that one ALIGN()
is sufficient.

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".

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).

However these functions expect bit numbers, while the flags are defined

Ojaswin Mujoo [Tue, 30 May 2023 12:33:39 +0000 (18:03 +0530)]
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.

13 months agomedia: uvcvideo: Don't expose unsupported formats to userspace

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

When the uvcvideo driver encounters a format descriptor with an unknown
format GUID, it creates a corresponding struct uvc_format instance with
the fcc field set to 0. Since commit 50459f103edf ("media: uvcvideo:
Remove format descriptions"), the driver relies on the V4L2 core to
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
applications. Ignore the format completely without creating a uvc_format
instance, which fixes the warning.

13 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.
