commit c3f3ce049f7d97cc7ec9c01cb51d9ec74e0f37c2 upstream.

The task structure is freed while get_mem_cgroup_from_mm() holds
rcu_read_lock() and dereferences mm->owner.

  get_mem_cgroup_from_mm()                failing fork()
  ----                                    ---
  task = mm->owner
                                          mm->owner = NULL;
                                          free(task)
  if (task) *task; /* use after free */

The fix consists in freeing the task with RCU also in the fork failure
case, exactly like it always happens for the regular exit(2) path.  That
is enough to make the rcu_read_lock hold in get_mem_cgroup_from_mm()
(left side above) effective to avoid a use after free when dereferencing
the task structure.

An alternate possible fix would be to defer the delivery of the
userfaultfd contexts to the monitor until after fork() is guaranteed to
succeed.  Such a change would require more changes because it would
create a strict ordering dependency where the uffd methods would need to
be called beyond the last potentially failing branch in order to be
safe.  This solution as opposed only adds the dependency to common code
to set mm->owner to NULL and to free the task struct that was pointed by
mm->owner with RCU, if fork ends up failing.  The userfaultfd methods
can still be called anywhere during the fork runtime and the monitor
will keep discarding orphaned "mm" coming from failed forks in userland.

This race condition couldn't trigger if CONFIG_MEMCG was set =n at build
time.

commit e091eab028f9253eac5c04f9141bbc9d170acab3 upstream.

In some cases, ocfs2_iget() reads the data of inode, which has been
deleted for some reason.  That will make the system panic.  So We should
judge whether this inode has been deleted, and tell the caller that the
inode is a bad inode.

For example, the ocfs2 is used as the backed of nfs, and the client is
nfsv3.  This issue can be reproduced by the following steps.

on the nfs server side,
..../patha/pathb

Step 1: The process A was scheduled before calling the function fh_verify.

Step 2: The process B is removing the 'pathb', and just completed the call
to function dput.  Then the dentry of 'pathb' has been deleted from the
dcache, and all ancestors have been deleted also.  The relationship of
dentry and inode was deleted through the function hlist_del_init.  The
following is the call stack.
dentry_iput->hlist_del_init(&dentry->d_u.d_alias)

At this time, the inode is still in the dcache.

Step 3: The process A call the function ocfs2_get_dentry, which get the
inode from dcache.  Then the refcount of inode is 1.  The following is the
call stack.
nfsd3_proc_getacl->fh_verify->exportfs_decode_fh->fh_to_dentry(ocfs2_get_dentry)

Step 4: Dirty pages are flushed by bdi threads.  So the inode of 'patha'
is evicted, and this directory was deleted.  But the inode of 'pathb'
can't be evicted, because the refcount of the inode was 1.

Step 5: The process A keep running, and call the function
reconnect_path(in exportfs_decode_fh), which call function
ocfs2_get_parent of ocfs2.  Get the block number of parent
directory(patha) by the name of ...  Then read the data from disk by the
block number.  But this inode has been deleted, so the system panic.

Process A                                             Process B

commit 1b426bac66e6cc83c9f2d92b96e4e72acf43419a upstream.

hugetlb uses a fault mutex hash table to prevent page faults of the
same pages concurrently.  The key for shared and private mappings is
different.  Shared keys off address_space and file index.  Private keys
off mm and virtual address.  Consider a private mappings of a populated
hugetlbfs file.  A fault will map the page from the file and if needed
do a COW to map a writable page.

Hugetlbfs hole punch uses the fault mutex to prevent mappings of file
pages.  It uses the address_space file index key.  However, private
mappings will use a different key and could race with this code to map
the file page.  This causes problems (BUG) for the page cache remove
code as it expects the page to be unmapped.  A sample stack is:

page dumped because: VM_BUG_ON_PAGE(page_mapped(page))
kernel BUG at mm/filemap.c:169!
...
RIP: 0010:unaccount_page_cache_page+0x1b8/0x200

There seems to be another potential COW issue/race with this approach
of different private and shared keys as noted in commit 8382d914
("mm, hugetlb: improve page-fault scalability").

Since every hugetlb mapping (even anon and private) is actually a file
mapping, just use the address_space index key for all mappings.  This
results in potentially more hash collisions.  However, this should not
be the common case.

Update the implementation to take a 'struct vm_fault' argument directly

commit 134fca9063ad4851de767d1768180e5dede9a881 upstream.

The semantics of what mincore() considers to be resident is not
completely clear, but Linux has always (since 2.3.52, which is when
mincore() was initially done) treated it as "page is available in page
cache".

That's potentially a problem, as that [in]directly exposes
meta-information about pagecache / memory mapping state even about
memory not strictly belonging to the process executing the syscall,
opening possibilities for sidechannel attacks.

Change the semantics of mincore() so that it only reveals pagecache
information for non-anonymous mappings that belog to files that the
calling process could (if it tried to) successfully open for writing;
otherwise we'd be including shared non-exclusive mappings, which

 - is the sidechannel

 - is not the usecase for mincore(), as that's primarily used for data,
   not (shared) text

commit a46eb523220e242affb9a6bc9bb8efc05f4f7459 upstream.

The current algorithm allows 3 types of transfers, 16bit, 32bit and
burst. According to Realtek, 16bit transfers have a special restriction
in that it is restricted to the memory region of
0x18020000 ~ 0x18021000. This region is the memory location of the I2C
registers. The current algorithm does not uphold this restriction and
therefore fails to complete writes.

Since this has been broken for some time it likely no one is using it.
Better to simply disable the 16 bit writes. This will allow users to
properly load firmware over SPI without data corruption.

commit ecb2795c08bc825ebd604997e5be440b060c5b18 upstream.

The max98090 driver defines 3 DAPM muxes; one for the right line output
(LINMOD Mux), one for the left headphone mixer source (MIXHPLSEL Mux)
and one for the right headphone mixer source (MIXHPRSEL Mux). The same
bit is used for the mux as well as the DAPM enable, and although the mux
can be correctly configured, after playback has completed, the mux will
be reset during the disable phase. This is preventing the state of these
muxes from being saved and restored correctly on system reboot. Fix this
by marking these muxes as SND_SOC_NOPM.

commit 7f641e26a6df9269cb25dd7a4b0a91d6586ed441 upstream.

On the machines with AMD GPU or Nvidia GPU, we often meet this issue:
after s3, there are 4 HDMI/DP audio devices in the gnome-sound-setting
even there is no any monitors plugged.

When this problem happens, we check the /proc/asound/cardX/eld#N.M, we
will find the monitor_present=1, eld_valid=0.

The root cause is BIOS or GPU driver makes the PRESENCE valid even no
monitor plugged, and of course the driver will not get the valid
eld_data subsequently.

In this situation, we should not report the jack_plugged event, to do
so, let us change the function hdmi_present_sense_via_verbs(). In this
function, it reads the pin_sense via snd_hda_pin_sense(), after
calling this function, the jack_dirty is 0, and before exiting
via_verbs(), we change the shadow pin_sense according to both
monitor_present and eld_valid, then in the snd_hda_jack_report_sync(),
since the jack_dirty is still 0, it will report jack event according
to this modified shadow pin_sense.

After this change, the driver will not report Jack_is_plugged event
through hdmi_present_sense_via_verbs() if monitor_present is 1 and
eld_valid is 0.

commit 8c2e6728c2bf95765b724e07d0278ae97cd1ee0d upstream.

The driver will check the monitor presence when resuming from suspend,
starting poll or interrupt triggers. In these 3 situations, the
jack_dirty will be set to 1 first, then the hda_jack.c reads the
pin_sense from register, after reading the register, the jack_dirty
will be set to 0. But hdmi_repoll_work() is enabled in these 3
situations, It will read the pin_sense a couple of times subsequently,
since the jack_dirty is 0 now, It does not read the register anymore,
instead it uses the shadow pin_sense which is read at the first time.

It is meaningless to check the shadow pin_sense a couple of times,
we need to read the register to check the real plugging state, so
we set the jack_dirty to 1 in the hdmi_repoll_work().

commit f699594d436960160f6d5ba84ed4a222f20d11cd upstream.

GCM instances can be created by either the "gcm" template, which only
allows choosing the block cipher, e.g. "gcm(aes)"; or by "gcm_base",
which allows choosing the ctr and ghash implementations, e.g.
"gcm_base(ctr(aes-generic),ghash-generic)".

However, a "gcm_base" instance prevents a "gcm" instance from being
registered using the same implementations.  Nor will the instance be
found by lookups of "gcm".  This can be used as a denial of service.
Moreover, "gcm_base" instances are never tested by the crypto
self-tests, even if there are compatible "gcm" tests.

The root cause of these problems is that instances of the two templates
use different cra_names.  Therefore, fix these problems by making
"gcm_base" instances set the same cra_name as "gcm" instances, e.g.
"gcm(aes)" instead of "gcm_base(ctr(aes-generic),ghash-generic)".

This requires extracting the block cipher name from the name of the ctr
algorithm.  It also requires starting to verify that the algorithms are
really ctr and ghash, not something else entirely.  But it would be
bizarre if anyone were actually using non-gcm-compatible algorithms with
gcm_base, so this shouldn't break anyone in practice.

The arm64 gcm-aes-ce algorithm is failing the extra crypto self-tests
following my patches to test the !may_use_simd() code paths, which
previously were untested.  The problem is that in the !may_use_simd()
case, an odd number of AES blocks can be processed within each step of
the skcipher_walk.  However, the skcipher_walk is being done with a
"stride" of 2 blocks and is advanced by an even number of blocks after
each step.  This causes the encryption to produce the wrong ciphertext
and authentication tag, and causes the decryption to incorrectly fail.

Fix it by only processing an even number of blocks per step.

commit dcaca01a42cc2c425154a13412b4124293a6e11e upstream.

skcipher_walk_done() assumes it's a bug if, after the "slow" path is
executed where the next chunk of data is processed via a bounce buffer,
the algorithm says it didn't process all bytes.  Thus it WARNs on this.

However, this can happen legitimately when the message needs to be
evenly divisible into "blocks" but isn't, and the algorithm has a
'walksize' greater than the block size.  For example, ecb-aes-neonbs
sets 'walksize' to 128 bytes and only supports messages evenly divisible
into 16-byte blocks.  If, say, 17 message bytes remain but they straddle
scatterlist elements, the skcipher_walk code will take the "slow" path
and pass the algorithm all 17 bytes in the bounce buffer.  But the
algorithm will only be able to process 16 bytes, triggering the WARN.

Fix this by just removing the WARN_ON().  Returning -EINVAL, as the code
already does, is the right behavior.

This bug was detected by my patches that improve testmgr to fuzz
algorithms against their generic implementation.

commit edaf28e996af69222b2cb40455dbb5459c2b875a upstream.

If the user-provided IV needs to be aligned to the algorithm's
alignmask, then skcipher_walk_virt() copies the IV into a new aligned
buffer walk.iv.  But skcipher_walk_virt() can fail afterwards, and then
if the caller unconditionally accesses walk.iv, it's a use-after-free.

salsa20-generic doesn't set an alignmask, so currently it isn't affected
by this despite unconditionally accessing walk.iv.  However this is more
subtle than desired, and it was actually broken prior to the alignmask
being removed by commit b62b3db7 ("crypto: salsa20-generic - cleanup
and convert to skcipher API").

Since salsa20-generic does not update the IV and does not need any IV
alignment, update it to use req->iv instead of walk.iv.

commit 7e92e1717e3eaf6b322c252947c696b3059f05be upstream.

Currently, crypto4xx CFB and OFB AES ciphers are
failing testmgr's test vectors.

|cfb-aes-ppc4xx encryption overran dst buffer on test vector 3, cfg="in-place"
|ofb-aes-ppc4xx encryption overran dst buffer on test vector 1, cfg="in-place"

This is because of a very subtile "bug" in the hardware that
gets indirectly mentioned in 18.1.3.5 Encryption/Decryption
of the hardware spec:

the OFB and CFB modes for AES are listed there as operation
modes for >>> "Block ciphers" <<<. Which kind of makes sense,
but we would like them to be considered as stream ciphers just
like the CTR mode.

To workaround this issue and stop the hardware from causing
"overran dst buffer" on crypttexts that are not a multiple
of 16 (AES_BLOCK_SIZE), we force the driver to use the scatter
buffers as the go-between.

As a bonus this patch also kills redundant pd_uinfo->num_gd
and pd_uinfo->num_sd setters since the value has already been
set before.
