commit 9b55d3f0a69af649c62cbc2633e6d695bb3cc583 upstream.
When converting net_device_stats to rtnl_link_stats64 sign extension
is triggered on ILP32 machines as 6c1c509778 changed the previous
"ulong -> u64" conversion to "long -> u64" by accessing the
net_device_stats fields through a (signed) atomic_long_t.
This causes for example the received bytes counter to jump to 16EiB after
having received 2^31 bytes. Casting the atomic value to "unsigned long"
beforehand converting it into u64 avoids this.
Fixes: 6c1c5097781f ("net: add atomic_long_t to net_device_stats fields")

commit 647037adcad00f2bab8828d3d41cd0553d41f3bd upstream.
This reverts commit 115d9d77bb0f9152c60b6e8646369fa7f6167593.
The pages being freed by memblock_free_late() have already been
initialized, but if they are in the deferred init range,
__free_one_page() might access nearby uninitialized pages when trying to
coalesce buddies. This can, for example, trigger this BUG:

Specifically it was missed that the second, unconditional,
wait_for_completion() was not optional and ensures the on-stack

commit 96a9c287e25d690fd9623b5133703b8e310fbed1 upstream.
Nick Bowler reported another sparc64 breakage after the young/dirty
persistent work for page migration (per "Link:" below). That's after a
similar report [2].
It turns out page migration was overlooked, and it wasn't failing before
because page migration was not enabled in the initial report test
environment.
David proposed another way [2] to fix this from sparc64 side, but that
patch didn't land somehow. Neither did I check whether there's any other
arch that has similar issues.
Let's fix it for now as simple as moving the write bit handling to be
after dirty, like what we did before.
Note: this is based on mm-unstable, because the breakage was since 6.1 and
we're at a very late stage of 6.2 (-rc8), so I assume for this specific
case we should target this at 6.3.

commit 5956592ce337330cdff0399a6f8b6a5aea397a8e upstream.
I was running traces of the read code against an RAID storage system to
understand why read requests were being misaligned against the underlying
RAID strips. I found that the page end offset calculation in
filemap_get_read_batch() was off by one.
When a read is submitted with end offset 1048575, then it calculates the
end page for read of 256 when it should be 255. "last_index" is the index
of the page beyond the end of the read and it should be skipped when get a
batch of pages for read in @filemap_get_read_batch().
The below simple patch fixes the problem. This code was introduced in
kernel 5.12.

commit ae63c898f4004bbc7d212f4adcb3bb14852c30d6 upstream.
During collapse, in a few places we check to see if a given small page has
any unaccounted references. If the refcount on the page doesn't match our
expectations, it must be there is an unknown user concurrently interested
in the page, and so it's not safe to move the contents elsewhere.
However, the unaccounted pins are likely an ephemeral state.
In this situation, MADV_COLLAPSE returns -EINVAL when it should return
-EAGAIN. This could cause userspace to conclude that the syscall
failed, when it in fact could succeed by retrying.

commit 99b9402a36f0799f25feee4465bfa4b8dfa74b4d upstream.
Macro NILFS_SB2_OFFSET_BYTES, which computes the position of the second
superblock, underflows when the argument device size is less than 4096
bytes. Therefore, when using this macro, it is necessary to check in
advance that the device size is not less than a lower limit, or at least
that underflow does not occur.
The current nilfs2 implementation lacks this check, causing out-of-bound
block access when mounting devices smaller than 4096 bytes:
I/O error, dev loop0, sector 36028797018963960 op 0x0:(READ) flags 0x0
phys_seg 1 prio class 2
NILFS (loop0): unable to read secondary superblock (blocksize = 1024)
In addition, when trying to resize the filesystem to a size below 4096
bytes, this underflow occurs in nilfs_resize_fs(), passing a huge number
of segments to nilfs_sufile_resize(), corrupting parameters such as the
number of segments in superblocks. This causes excessive loop iterations
in nilfs_sufile_resize() during a subsequent resize ioctl, causing
semaphore ns_segctor_sem to block for a long time and hang the writer
thread:

commit ec4288fe63966b26d53907212ecd05dfa81dd2cc upstream.
Users can specify the hugetlb page size in the mmap, shmget and
memfd_create system calls. This is done by using 6 bits within the flags
argument to encode the base-2 logarithm of the desired page size. The
routine hstate_sizelog() uses the log2 value to find the corresponding
hugetlb hstate structure. Converting the log2 value (page_size_log) to
potential hugetlb page size is the simple statement:
1UL << page_size_log
Because only 6 bits are used for page_size_log, the left shift can not be
greater than 63. This is fine on 64 bit architectures where a long is 64
bits. However, if a value greater than 31 is passed on a 32 bit
architecture (where long is 32 bits) the shift will result in undefined
behavior. This was generally not an issue as the result of the undefined
shift had to exactly match hugetlb page size to proceed.
Recent improvements in runtime checking have resulted in this undefined
behavior throwing errors such as reported below.
Fix by comparing page_size_log to BITS_PER_LONG before doing shift.

commit c2dbe32d5db5c4ead121cf86dabd5ab691fb47fe upstream.
If a non-root cgroup gets removed when there is a thread that registered
trigger and is polling on a pressure file within the cgroup, the polling
waitqueue gets freed in the following path:
do_rmdir
cgroup_rmdir
kernfs_drain_open_files
cgroup_file_release
cgroup_pressure_release
psi_trigger_destroy
However, the polling thread still has a reference to the pressure file and
will access the freed waitqueue when the file is closed or upon exit:
fput
ep_eventpoll_release
ep_free
ep_remove_wait_queue
remove_wait_queue
This results in use-after-free as pasted below.
The fundamental problem here is that cgroup_file_release() (and
consequently waitqueue's lifetime) is not tied to the file's real lifetime.
Using wake_up_pollfree() here might be less than ideal, but it is in line
with the comment at commit 42288cb44c4b ("wait: add wake_up_pollfree()")
since the waitqueue's lifetime is not tied to file's one and can be
considered as another special case. While this would be fixable by somehow
making cgroup_file_release() be tied to the fput(), it would require
sizable refactoring at cgroups or higher layer which might be more
justifiable if we identify more cases like this.

commit 3af4a4f7a20c94009adba65764fa5a0269d70a82 upstream.
Commit f2bd1c5ae2cb ("ALSA: hda: Fix page fault in
snd_hda_codec_shutdown()") relocated initialization of several codec
device fields. Due to differences between codec_exec_verb() and
snd_hdac_bus_exec_bus() in how they handle VERB execution - the latter
does not touch PM - assigning ->exec_verb to codec_exec_verb() causes PM
to be engaged before it is configured for the device. Configuration of
PM for the ASoC HDAudio sound card is done with snd_hda_set_power_save()
during skl_hda_audio_probe() whereas the assignment happens early, in
snd_hda_codec_device_init().
Revert to previous behavior to avoid problems caused by too early PM
manipulation.

commit 605d9fb9556f8f5fb4566f4df1480f280f308ded upstream.
If sdio_add_func() or sdio_init_func() fails, sdio_remove_func() can
not release the resources, because the sdio function is not presented
in these two cases, it won't call of_node_put() or put_device().
To fix these leaks, make sdio_func_present() only control whether
device_del() needs to be called or not, then always call of_node_put()
and put_device().
In error case in sdio_init_func(), the reference of 'card->dev' is
not get, to avoid redundant put in sdio_free_func_cis(), move the
get_device() to sdio_alloc_func() and put_device() to sdio_release_func(),
it can keep the get/put function be balanced.
Without this patch, while doing fault inject test, it can get the
following leak reports, after this fix, the leak is gone.

v3: Fix vmw_user_bo_lookup which was also dropping the gem reference
before the kernel was done with buffer depending on userspace doing
the right thing. Same bug, different spot.
It is possible for userspace to predict the next buffer handle and
to destroy the buffer while it's still used by the kernel. Delay
dropping the internal reference on the buffers until kernel is done
with them.
Instead of immediately dropping the gem reference in vmw_user_bo_lookup
and vmw_gem_object_create_with_handle let the callers decide when they're
ready give the control back to userspace.
Also fixes the second usage of vmw_gem_object_create_with_handle in
vmwgfx_surface.c which wasn't grabbing an explicit reference
to the gem object which could have been destroyed by the userspace
on the owning surface at any point.

ttm_bo_init_reserved on failure puts the buffer object back which

After the double free the vmw_gem_object_create_with_handle was

Fix the entire path by relaying on ttm_bo_init_reserved to delete the

drivers totally undebuggable.
There's a more complete fix in progress [1], with further details, but
we need this fixed in stable kernels. Mark the feature as broken and
disable it by default, with hopes distros follow suit and disable it as
well.

commit badc28d4924bfed73efc93f716a0c3aa3afbdf6f upstream.
The debugfs_remove_recursive() is invoked by unregister_shrinker(), which
is holding the write lock of shrinker_rwsem. It will waits for the
handler of debugfs file complete. The handler also needs to hold the read
lock of shrinker_rwsem to do something. So it may cause the following
deadlock:
CPU0 CPU1
debugfs_file_get()
shrinker_debugfs_count_show()/shrinker_debugfs_scan_write()
unregister_shrinker()
--> down_write(&shrinker_rwsem);
debugfs_remove_recursive()
// wait for (A)
--> wait_for_completion();
// wait for (B)
--> down_read_killable(&shrinker_rwsem)
debugfs_file_put() -- (A)
up_write() -- (B)
The down_read_killable() can be killed, so that the above deadlock can be
recovered. But it still requires an extra kill action, otherwise it will
block all subsequent shrinker-related operations, so it's better to fix
it.

commit ce4d9a1ea35ac5429e822c4106cb2859d5c71f3e upstream.
Patch series "Fix kmemleak crashes when scanning CMA regions", v2.
When trying to boot a device with an ARM64 kernel with the following
config options enabled:
CONFIG_DEBUG_PAGEALLOC=y
CONFIG_DEBUG_PAGEALLOC_ENABLE_DEFAULT=y
CONFIG_DEBUG_KMEMLEAK=y
a crash is encountered when kmemleak starts to scan the list of gray
or allocated objects that it maintains. Upon closer inspection, it was
observed that these page-faults always occurred when kmemleak attempted
to scan a CMA region.
At the moment, kmemleak is made aware of CMA regions that are specified
through the devicetree to be dynamically allocated within a range of
addresses. However, kmemleak should not need to scan CMA regions or any
reserved memory region, as those regions can be used for DMA transfers
between drivers and peripherals, and thus wouldn't contain anything
useful for kmemleak.
Additionally, since CMA regions are unmapped from the kernel's address
space when they are freed to the buddy allocator at boot when
CONFIG_DEBUG_PAGEALLOC is enabled, kmemleak shouldn't attempt to access
those memory regions, as that will trigger a crash. Thus, kmemleak
should ignore all dynamically allocated reserved memory regions.
This patch (of 1):
Currently, kmemleak ignores dynamically allocated reserved memory regions
that don't have a kernel mapping. However, regions that do retain a
kernel mapping (e.g. CMA regions) do get scanned by kmemleak.
This is not ideal for two reasons:
1 kmemleak works by scanning memory regions for pointers to allocated
objects to determine if those objects have been leaked or not.
However, reserved memory regions can be used between drivers and
peripherals for DMA transfers, and thus, would not contain pointers to
allocated objects, making it unnecessary for kmemleak to scan these
reserved memory regions.
2 When CONFIG_DEBUG_PAGEALLOC is enabled, along with kmemleak, the
CMA reserved memory regions are unmapped from the kernel's address
space when they are freed to buddy at boot. These CMA reserved regions
are still tracked by kmemleak, however, and when kmemleak attempts to
scan them, a crash will happen, as accessing the CMA region will result
in a page-fault, since the regions are unmapped.
Thus, use kmemleak_ignore_phys() for all dynamically allocated reserved
memory regions, instead of those that do not have a kernel mapping
associated with them.

The commit 4656d72c1efa ("selftests: mptcp: userspace: validate v4-v6 subflows mix")
has been backported to v6.1.8 without any conflicts. But it looks like
it was depending on a previous one:
commit 1cc94ac1af4b ("selftests: mptcp: make evts global in userspace_pm")
Without it, the test fails with:
./userspace_pm.sh: line 788: : No such file or directory
# ADD_ADDR4 id:14 10.0.2.1 (ns1) => ns2, reuse port [FAIL]
sed: can't read : No such file or directory
This dependence refactors the way the monitoring files are being
created: only once for all the different sub-tests instead of per
sub-test.
It is probably better to avoid backporting the refactoring. That is why
the new sub-test has been adapted to work using the previous way that is
still in place here in v6.1: the monitoring is started at the beginning
of each sub-test and the created file is removed at the end.

This patch will just block all the further IO/MDS requests

The reason why we still need to evict the kclient just after

[ Upstream commit 275d8a1db261a1272a818d40ebc61b3b865b60e5 ]
[Why]
The hwss function does_plane_fit_in_mall not applicable to dcn3.2 asics.
Using it with dcn3.2 can result in undefined behaviour.
[How]
Assign the function pointer to NULL.

In nvme_alloc_io_tag_set(), the connect_q pointer should be set to NULL
in case of error to avoid potential invalid pointer dereferences.

[ Upstream commit fd62678ab55cb01e11a404d302cdade222bf4022 ]
If nvme_alloc_admin_tag_set() fails, the admin_q and fabrics_q pointers
are left with an invalid, non-NULL value. Other functions may then check
the pointers and dereference them, e.g. in
nvme_probe() -> out_disable: -> nvme_dev_remove_admin().
Fix the bug by setting admin_q and fabrics_q to NULL in case of error.
Also use the set variable to free the tag_set as ctrl->admin_tagset isn't
initialized yet.

As part of nvmet_fc_ls_create_association there is a case where
nvmet_fc_alloc_target_queue fails right after a new association with an
admin queue is created. In this case, no one releases the get taken in
nvmet_fc_alloc_target_assoc. This fix is adding the missing put.

[ Upstream commit 7ab41c2c08a32132ba8c14624910e2fe8ce4ba4b ]
Historically calls to __decompress() didn't specify "out_len" parameter
on many architectures including s390, expecting that no writes beyond
uncompressed kernel image are performed. This has changed since commit
2aa14b1ab2c4 ("zstd: import usptream v1.5.2") which includes zstd library
commit 6a7ede3dfccb ("Reduce size of dctx by reutilizing dst buffer
(#2751)"). Now zstd decompression code might store literal buffer in
the unwritten portion of the destination buffer. Since "out_len" is
not set, it is considered to be unlimited and hence free to use for
optimization needs. On s390 this might corrupt initrd or ipl report
which are often placed right after the decompressor buffer. Luckily the
size of uncompressed kernel image is already known to the decompressor,
so to avoid the problem simply specify it in the "out_len" parameter.
