Commit 91419ae042 ("arm64: dts: rockchip: use BCLK to GPIO switch on
rk3399") modified i2s0 to switch the corresponding pins off when idle.
For the ROCK Pi 4 boards, this means that i2s0 has the following pinctrl
setting:
pinctrl-names = "bclk_on", "bclk_off";
pinctrl-0 = <&i2s0_2ch_bus>;
pinctrl-1 = <&i2s0_8ch_bus_bclk_off>;
Due to this change, i2s0 fails to probe on my Radxa ROCK 4SE and ROCK Pi
4B boards:
rockchip-pinctrl pinctrl: pin gpio3-29 already requested by leds; cannot claim for ff880000.i2s
rockchip-pinctrl pinctrl: pin-125 (ff880000.i2s) status -22
rockchip-pinctrl pinctrl: could not request pin 125 (gpio3-29) from group i2s0-8ch-bus-bclk-off on device rockchip-pinctrl
rockchip-i2s ff880000.i2s: Error applying setting, reverse things back
rockchip-i2s ff880000.i2s: bclk disable failed -22
A pin requested for i2s0_8ch_bus_bclk_off has already been requested by
user_led2, so whichever driver probes first will have the pin allocated.
The hardware uses 2-channel i2s so fix this error by setting pinctl-1 to
i2s0_2ch_bus_bclk_off which doesn't contain the pin allocated to user_led2.
I checked the schematics for all Radxa boards based on ROCK Pi 4 and this
change is compatible with all boards.

For unmapping any buffer from kernel, it should first be unmapped
from DSP. In case unmap from DSP request fails, the map should not
be removed from kernel as it might lead to SMMU faults and other

The FDs for DMA handles to be freed is updated in fdlist by DSP over
a remote call. This holds true even for remote calls with no

be called for remote calls with no arguments also as fdlist
is allocated in get_args and FDs updated in fdlist is freed

Metadata buffer is allocated during get_args for any remote call.
This buffer carries buffers, fdlists and other payload information
for the call. If the buffer is not reset, put_args might find some
garbage FDs in the fdlist which might have an existing mapping in
the list. This could result in improper freeing of FD map when DSP
might still be using the buffer. Added change to reset the metadata
buffer after allocation.

The MediaTek DRM driver implements GEM PRIME vmap by fetching the
sg_table for the object, iterating through the pages, and then
vmapping them. In essence, unlike the GEM DMA helpers which vmap
when the object is first created or imported, the MediaTek version
does it on request.
Unfortunately, the code never correctly frees the sg_table contents.
This results in a kernel memory leak. On a Hayato device with a text
console on the internal display, this results in the system running
out of memory in a few days from all the console screen cursor updates.
Add sg_free_table() to correctly free the contents of the sg_table. This
was missing despite explicitly required by mtk_gem_prime_get_sg_table().
Also move the "out" shortcut label to after the kfree() call for the
sg_table. Having sg_free_table() together with kfree() makes more sense.
The shortcut is only used when the object already has a kernel address,
in which case the pointer is NULL and kfree() does nothing. Hence this
change causes no functional change.

The Qualcomm LPASS LPI pin controller driver uses one lock for guarding
Read-Modify-Write code for slew rate registers. However the pin
configuration and muxing registers have exactly the same RMW code but
are not protected.
Pin controller framework does not provide locking here, thus it is
possible to trigger simultaneous change of pin configuration registers
resulting in non-atomic changes.
Protect from concurrent access by re-using the same lock used to cover
the slew rate register. Using the same lock instead of adding second
one will make more sense, once we add support for newer Qualcomm SoC,
where slew rate is configured in the same register as pin
configuration/muxing.

When physical memory is defined under z/VM using DEF STOR CONFIG, there
may be memory holes that are not hotpluggable memory. In such cases,
DCSS mapping could be placed in one of these memory holes. Subsequently,
attempting memory access to such DCSS mapping would result in a kasan
failure because there is no shadow memory mapping for it.
To maintain consistency with cases where DCSS mapping is positioned after
the kernel identity mapping, which is then covered by kasan zero shadow
mapping, handle the scenario above by populating zero shadow mapping
for memory holes where DCSS mapping could potentially be placed.

Both the JEDEC and ONFI specification say that read cache sequential
support is an optional command. This means that we not only need to
check whether the individual controller supports the command, we also
need to check the parameter pages for both ONFI and JEDEC NAND flashes
before enabling sequential cache reads.
This fixes support for NAND flashes which don't support enabling cache
reads, i.e. Samsung K9F4G08U0F or Toshiba TC58NVG0S3HTA00.
Sequential cache reads are now only available for ONFI and JEDEC
devices, if individual vendors implement this, it needs to be enabled
per vendor.
Tested on i.MX6Q with a Samsung NAND flash chip that doesn't support
sequential reads.

Paolo Abeni reports that on some systems the pyroute2 version isn't
new enough to run the test suite. Ensure that we support a minimum
version of 0.6 for all cases (which does include the existing ones).
The 0.6.1 version was released in May of 2021, so should be
propagated to most installations at this point.
The alternative that Paolo proposed was to only skip when the
add-flow is being run. This would be okay for most cases, except
if a future test case is added that needs to do flow dump without
an associated add (just guessing). In that case, it could also be
broken and we would need additional skip logic anyway. Just draw
a line in the sand now.

Ashok Raj chimes in:
"There was a report (probably this same one), and it turns out it was a
bug in the BIOS SMI handler.
The client BIOS's were waiting for the lowest APICID to be the SMI
rendevous master. If this is MeteorLake, the BSP wasn't the one with
the lowest APIC and it triped here.
The BIOS change is also being pushed to others for assimilation :)
Server BIOS's had this correctly for a while now"
and it does look likely to be some bad interaction between SMI and the
non-BSP cores having put into INIT (and thus unresponsive until reset).

New virtio types can have tighter validation. Limit UDP GSO packets

Commit f6fca3917b "btrfs: store chunk size in space-info struct"
broke data chunk allocations on non-zoned multi-device filesystems when
using default chunk_size. Commit 5da431b71d "btrfs: fix the max chunk
size and stripe length calculation" partially fixed that, and this patch
completes the fix for that case.
After commit f6fca3917b and 5da431b71d, the sequence of events for
a data chunk allocation on a non-zoned filesystem is:
1. btrfs_create_chunk calls init_alloc_chunk_ctl, which copies
space_info->chunk_size (default 10 GiB) to ctl->max_stripe_len
unmodified. Before f6fca3917b, ctl->max_stripe_len value was
1 GiB for non-zoned data chunks and not configurable.
2. btrfs_create_chunk calls gather_device_info which consumes
and produces more fields of chunk_ctl.
3. gather_device_info multiplies ctl->max_stripe_len by
ctl->dev_stripes (which is 1 in all cases except dup)
and calls find_free_dev_extent with that number as num_bytes.
4. find_free_dev_extent locates the first dev_extent hole on
a device which is at least as large as num_bytes. With default
max_chunk_size from f6fca3917b, it finds the first hole which is
longer than 10 GiB, or the largest hole if that hole is shorter
than 10 GiB. This is different from the pre-f6fca3917b4d
behavior, where num_bytes is 1 GiB, and find_free_dev_extent
may choose a different hole.
5. gather_device_info repeats step 4 with all devices to find
the first or largest dev_extent hole that can be allocated on
each device.
6. gather_device_info sorts the device list by the hole size
on each device, using total unallocated space on each device to
break ties, then returns to btrfs_create_chunk with the list.
7. btrfs_create_chunk calls decide_stripe_size_regular.
8. decide_stripe_size_regular finds the largest stripe_len that
fits across the first nr_devs device dev_extent holes that were
found by gather_device_info (and satisfies other constraints
on stripe_len that are not relevant here).
9. decide_stripe_size_regular caps the length of the stripe it
computed at 1 GiB. This cap appeared in 5da431b71d to correct
one of the other regressions introduced in f6fca3917b.
10. btrfs_create_chunk creates a new chunk with the above
computed size and number of devices.
At step 4, gather_device_info() has found a location where stripe up to
10 GiB in length could be allocated on several devices, and selected
which devices should have a dev_extent allocated on them, but at step
9, only 1 GiB of the space that was found on each device can be used.
This mismatch causes new suboptimal chunk allocation cases that did not
occur in pre-f6fca3917b4d kernels.
Consider a filesystem using raid1 profile with 3 devices. After some
balances, device 1 has 10x 1 GiB unallocated space, while devices 2
and 3 have 1x 10 GiB unallocated space, i.e. the same total amount of
space, but distributed across different numbers of dev_extent holes.
For visualization, let's ignore all the chunks that were allocated before
this point, and focus on the remaining holes:
Device 1: [_] [_] [_] [_] [_] [_] [_] [_] [_] [_] (10x 1 GiB unallocated)
Device 2: [__________] (10 GiB contig unallocated)
Device 3: [__________] (10 GiB contig unallocated)
Before f6fca3917b, the allocator would fill these optimally by
allocating chunks with dev_extents on devices 1 and 2 ([12]), 1 and 3
([13]), or 2 and 3 ([23]):
[after 0 chunk allocations]
Device 1: [_] [_] [_] [_] [_] [_] [_] [_] [_] [_] (10 GiB)
Device 2: [__________] (10 GiB)
Device 3: [__________] (10 GiB)
[after 1 chunk allocation]
Device 1: [12] [_] [_] [_] [_] [_] [_] [_] [_] [_]
Device 2: [12] [_________] (9 GiB)
Device 3: [__________] (10 GiB)
[after 2 chunk allocations]
Device 1: [12] [13] [_] [_] [_] [_] [_] [_] [_] [_] (8 GiB)
Device 2: [12] [_________] (9 GiB)
Device 3: [13] [_________] (9 GiB)
[after 3 chunk allocations]
Device 1: [12] [13] [12] [_] [_] [_] [_] [_] [_] [_] (7 GiB)
Device 2: [12] [12] [________] (8 GiB)
Device 3: [13] [_________] (9 GiB)
[...]
[after 12 chunk allocations]
Device 1: [12] [13] [12] [13] [12] [13] [12] [13] [_] [_] (2 GiB)
Device 2: [12] [12] [23] [23] [12] [12] [23] [23] [__] (2 GiB)
Device 3: [13] [13] [23] [23] [13] [23] [13] [23] [__] (2 GiB)
[after 13 chunk allocations]
Device 1: [12] [13] [12] [13] [12] [13] [12] [13] [12] [_] (1 GiB)
Device 2: [12] [12] [23] [23] [12] [12] [23] [23] [12] [_] (1 GiB)
Device 3: [13] [13] [23] [23] [13] [23] [13] [23] [__] (2 GiB)
[after 14 chunk allocations]
Device 1: [12] [13] [12] [13] [12] [13] [12] [13] [12] [13] (full)
Device 2: [12] [12] [23] [23] [12] [12] [23] [23] [12] [_] (1 GiB)
Device 3: [13] [13] [23] [23] [13] [23] [13] [23] [13] [_] (1 GiB)
[after 15 chunk allocations]
Device 1: [12] [13] [12] [13] [12] [13] [12] [13] [12] [13] (full)
Device 2: [12] [12] [23] [23] [12] [12] [23] [23] [12] [23] (full)
Device 3: [13] [13] [23] [23] [13] [23] [13] [23] [13] [23] (full)
This allocates all of the space with no waste. The sorting function used
by gather_device_info considers free space holes above 1 GiB in length
to be equal to 1 GiB, so once find_free_dev_extent locates a sufficiently
long hole on each device, all the holes appear equal in the sort, and the
comparison falls back to sorting devices by total free space. This keeps
usable space on each device equal so they can all be filled completely.
After f6fca3917b, the allocator prefers the devices with larger holes
over the devices with more free space, so it makes bad allocation choices:
[after 1 chunk allocation]
Device 1: [_] [_] [_] [_] [_] [_] [_] [_] [_] [_] (10 GiB)
Device 2: [23] [_________] (9 GiB)
Device 3: [23] [_________] (9 GiB)
[after 2 chunk allocations]
Device 1: [_] [_] [_] [_] [_] [_] [_] [_] [_] [_] (10 GiB)
Device 2: [23] [23] [________] (8 GiB)
Device 3: [23] [23] [________] (8 GiB)
[after 3 chunk allocations]
Device 1: [_] [_] [_] [_] [_] [_] [_] [_] [_] [_] (10 GiB)
Device 2: [23] [23] [23] [_______] (7 GiB)
Device 3: [23] [23] [23] [_______] (7 GiB)
[...]
[after 9 chunk allocations]
Device 1: [_] [_] [_] [_] [_] [_] [_] [_] [_] [_] (10 GiB)
Device 2: [23] [23] [23] [23] [23] [23] [23] [23] [23] [_] (1 GiB)
Device 3: [23] [23] [23] [23] [23] [23] [23] [23] [23] [_] (1 GiB)
[after 10 chunk allocations]
Device 1: [12] [_] [_] [_] [_] [_] [_] [_] [_] [_] (9 GiB)
Device 2: [23] [23] [23] [23] [23] [23] [23] [23] [12] (full)
Device 3: [23] [23] [23] [23] [23] [23] [23] [23] [_] (1 GiB)
[after 11 chunk allocations]
Device 1: [12] [13] [_] [_] [_] [_] [_] [_] [_] [_] (8 GiB)
Device 2: [23] [23] [23] [23] [23] [23] [23] [23] [12] (full)
Device 3: [23] [23] [23] [23] [23] [23] [23] [23] [13] (full)
No further allocations are possible, with 8 GiB wasted (4 GiB of data
space). The sort in gather_device_info now considers free space in
holes longer than 1 GiB to be distinct, so it will prefer devices 2 and
3 over device 1 until all but 1 GiB is allocated on devices 2 and 3.
At that point, with only 1 GiB unallocated on every device, the largest
hole length on each device is equal at 1 GiB, so the sort finally moves
to ordering the devices with the most free space, but by this time it
is too late to make use of the free space on device 1.
Note that it's possible to contrive a case where the pre-f6fca3917b4d
allocator fails the same way, but these cases generally have extensive
dev_extent fragmentation as a precondition (e.g. many holes of 768M
in length on one device, and few holes 1 GiB in length on the others).
With the regression in f6fca3917b, bad chunk allocation can occur even
under optimal conditions, when all dev_extent holes are exact multiples
of stripe_len in length, as in the example above.
Also note that post-f6fca3917b4d kernels do treat dev_extent holes
larger than 10 GiB as equal, so the bad behavior won't show up on a
freshly formatted filesystem; however, as the filesystem ages and fills
up, and holes ranging from 1 GiB to 10 GiB in size appear, the problem
can show up as a failure to balance after adding or removing devices,
or an unexpected shortfall in available space due to unequal allocation.
To fix the regression and make data chunk allocation work
again, set ctl->max_stripe_len back to the original SZ_1G, or
space_info->chunk_size if that's smaller (the latter can happen if the
user set space_info->chunk_size to less than 1 GiB via sysfs, or it's
a 32 MiB system chunk with a hardcoded chunk_size and stripe_len).
While researching the background of the earlier commits, I found that an
identical fix was already proposed at:
https://lore.kernel.org/linux-btrfs/de83ac46-a4a3-88d3-85ce-255b7abc5249@gmx.com/
The previous review missed one detail: ctl->max_stripe_len is used
before decide_stripe_size_regular() is called, when it is too late for
the changes in that function to have any effect. ctl->max_stripe_len is
not used directly by decide_stripe_size_regular(), but the parameter
does heavily influence the per-device free space data presented to
the function.

Merge tag 'kvm-x86-selftests-6.6-fixes' of https://github.com/kvm-x86/linux into HEAD
KVM selftests fixes for 6.6:
- Play nice with %llx when formatting guest printf and assert statements.
- Clean up stale test metadata.
- Zero-initialize structures in memslot perf test to workaround a suspected
"may be used uninitialized" false positives from GCC.
- Truncate writes to PMU counters to the counter's width to avoid spurious
overflows when emulating counter events in software.
- Set the LVTPC entry mask bit when handling a PMI (to match Intel-defined
architectural behavior).
- Treat KVM_REQ_PMI as a wake event instead of queueing host IRQ work to
kick the guest out of emulated halt.

KVM/arm64 fixes for 6.6, take #2

Christophe reported that the change to ARCH_FORCE_MAX_ORDER to limit the
range to 10 had broken his ability to configure hugepages:
# echo 1 > /sys/kernel/mm/hugepages/hugepages-8192kB/nr_hugepages
sh: write error: Invalid argument
Several of the powerpc defconfigs previously set the
ARCH_FORCE_MAX_ORDER value to 12, via the definition in
arch/powerpc/configs/fsl-emb-nonhw.config, used by:
mpc85xx_defconfig
mpc85xx_smp_defconfig
corenet32_smp_defconfig
corenet64_smp_defconfig
mpc86xx_defconfig
mpc86xx_smp_defconfig
Fix it by increasing the allowed range to 12 to restore the previous
behaviour.

Kernel v6.5 converted overlayfs to new mount api.
As an added bonus, it also added a feature to allow appending lowerdirs
using lowerdir=:/lower2,lowerdir=::/data3 syntax.
This new syntax has raised some concerns regarding escaping of colons.
We decided to try and disable this syntax, which hasn't been in the wild
for so long and introduce it again in 6.7 using explicit mount options
lowerdir+=/lower2,datadir+=/data3.
