13d3be4ddf dsp: q6adm: Resolve mem corruption in adm cb
Conversion of negative "num_modules" var value
will result in max possible unsigned int value
and hence can cause mem corruption when accessed.

Resolve this by assigning the same data type
to "num_modules" var as used in the calling fn.

4d08c0d1d1 UPSTREAM: net/sched: sch_hfsc: Ensure inner classes have fsc curve
[ Upstream commit b3d26c5702c7d6c45456326e56d2ccf3f103e60f ]

HFSC assumes that inner classes have an fsc curve, but it is currently
possible for classes without an fsc curve to become parents. This leads
to bugs including a use-after-free.

Don't allow non-root classes without HFSC_FSC to become parents.

8daba3e055 UPSTREAM: net: sched: sch_qfq: Fix UAF in qfq_dequeue()
[ Upstream commit 8fc134fee27f2263988ae38920bc03da416b03d8 ]

When the plug qdisc is used as a class of the qfq qdisc it could trigger a
UAF. This issue can be reproduced with following commands:

  tc qdisc add dev lo root handle 1: qfq
  tc class add dev lo parent 1: classid 1:1 qfq weight 1 maxpkt 512
  tc qdisc add dev lo parent 1:1 handle 2: plug
  tc filter add dev lo parent 1: basic classid 1:1
  ping -c1 127.0.0.1

and boom:

4f38dc8496 net/sched: cls_fw: No longer copy tcf_result on update to avoid use-after-free
commit 76e42ae831991c828cffa8c37736ebfb831ad5ec upstream.

When fw_change() is called on an existing filter, the whole
tcf_result struct is always copied into the new instance of the filter.

This causes a problem when updating a filter bound to a class,
as tcf_unbind_filter() is always called on the old instance in the
success path, decreasing filter_cnt of the still referenced class
and allowing it to be deleted, leading to a use-after-free.

Fix this by no longer copying the tcf_result struct from the old filter.

126d5a99e5 btrfs: fix lockdep splat and potential deadlock after failure running delayed items
commit e110f8911ddb93e6f55da14ccbbe705397b30d0b upstream.

When running delayed items we are holding a delayed node's mutex and then
we will attempt to modify a subvolume btree to insert/update/delete the
delayed items. However if have an error during the insertions for example,
btrfs_insert_delayed_items() may return with a path that has locked extent
buffers (a leaf at the very least), and then we attempt to release the
delayed node at __btrfs_run_delayed_items(), which requires taking the
delayed node's mutex, causing an ABBA type of deadlock. This was reported
by syzbot and the lockdep splat is the following:

b94e604307 attr: block mode changes of symlinks
commit 5d1f903f75a80daa4dfb3d84e114ec8ecbf29956 upstream.

Changing the mode of symlinks is meaningless as the vfs doesn't take the
mode of a symlink into account during path lookup permission checking.

However, the vfs doesn't block mode changes on symlinks. This however,
has lead to an untenable mess roughly classifiable into the following
two categories:

(1) Filesystems that don't implement a i_op->setattr() for symlinks.

    Such filesystems may or may not know that without i_op->setattr()
    defined, notify_change() falls back to simple_setattr() causing the
    inode's mode in the inode cache to be changed.

    That's a generic issue as this will affect all non-size changing
    inode attributes including ownership changes.

    Example: afs

(2) Filesystems that fail with EOPNOTSUPP but change the mode of the
    symlink nonetheless.

    Some filesystems will happily update the mode of a symlink but still
    return EOPNOTSUPP. This is the biggest source of confusion for
    userspace.

    The EOPNOTSUPP in this case comes from POSIX ACLs. Specifically it
    comes from filesystems that call posix_acl_chmod(), e.g., btrfs via

        if (!err && attr->ia_valid & ATTR_MODE)
                err = posix_acl_chmod(idmap, dentry, inode->i_mode);

    Filesystems including btrfs don't implement i_op->set_acl() so
    posix_acl_chmod() will report EOPNOTSUPP.

    When posix_acl_chmod() is called, most filesystems will have
    finished updating the inode.

    Perversely, this has the consequences that this behavior may depend
    on two kconfig options and mount options:

    * CONFIG_POSIX_ACL={y,n}
    * CONFIG_${FSTYPE}_POSIX_ACL={y,n}
    * Opt_acl, Opt_noacl

    Example: btrfs, ext4, xfs

The only way to change the mode on a symlink currently involves abusing
an O_PATH file descriptor in the following manner:

        fd = openat(-1, "/path/to/link", O_CLOEXEC | O_PATH | O_NOFOLLOW);

        char path[PATH_MAX];
        snprintf(path, sizeof(path), "/proc/self/fd/%d", fd);
        chmod(path, 0000);

But for most major filesystems with POSIX ACL support such as btrfs,
ext4, ceph, tmpfs, xfs and others this will fail with EOPNOTSUPP with
the mode still updated due to the aforementioned posix_acl_chmod()
nonsense.

So, given that for all major filesystems this would fail with EOPNOTSUPP
and that both glibc (cf. [1]) and musl (cf. [2]) outright block mode
changes on symlinks we should just try and block mode changes on
symlinks directly in the vfs and have a clean break with this nonsense.

If this causes any regressions, we do the next best thing and fix up all
filesystems that do return EOPNOTSUPP with the mode updated to not call
posix_acl_chmod() on symlinks.

But as usual, let's try the clean cut solution first. It's a simple
patch that can be easily reverted. Not marking this for backport as I'll
do that manually if we're reasonably sure that this works and there are
no strong objections.

We could block this in chmod_common() but it's more appropriate to do it
notify_change() as it will also mean that we catch filesystems that
change symlink permissions explicitly or accidently.

Similar proposals were floated in the past as in [3] and [4] and again
recently in [5]. There's also a couple of bugs about this inconsistency
as in [6] and [7].

[ Upstream commit 4d0fe8c52bb3029d83e323c961221156ab98680b ]

When I register a kset in the following way:
	static struct kset my_kset;
	kobject_set_name(&my_kset.kobj, "my_kset");
        ret = kset_register(&my_kset);

A null pointer dereference exception is occurred:

Because I didn't initialize my_kset.kobj.ktype.

According to the description in Documentation/core-api/kobject.rst:
 - A ktype is the type of object that embeds a kobject.  Every structure
   that embeds a kobject needs a corresponding ktype.

So add sanity check to make sure kset->kobj.ktype is not NULL.

[ Upstream commit 801f287c93ff95582b0a2d2163f12870a2f076d4 ]

The function lio_target_nacl_info_show() uses sprintf() in a loop to print
details for every iSCSI connection in a session without checking for the
buffer length. With enough iSCSI connections it's possible to overflow the
buffer provided by configfs and corrupt the memory.

This patch replaces sprintf() with sysfs_emit_at() that checks for buffer
boundries.

JFS_SBI(ipbmap->i_sb)->bmap wasn't set to NULL after kfree() in
dbUnmount().

Syzkaller uses faultinject to reproduce this KASAN double-free
warning. The issue is triggered if either diMount() or dbMount() fail
in jfs_remount(), since diUnmount() or dbUnmount() already happened in
such a case - they will do double-free on next execution: jfs_umount
or jfs_remount.

Tested on both upstream and jfs-next by syzkaller.

2e060f5f26 ext2: fix datatype of block number in ext2_xattr_set2()
[ Upstream commit e88076348425b7d0491c8c98d8732a7df8de7aa3 ]

I run a small server that uses external hard drives for backups. The
backup software I use uses ext2 filesystems with 4KiB block size and
the server is running SELinux and therefore relies on xattr. I recently
upgraded the hard drives from 4TB to 12TB models. I noticed that after
transferring some TBs I got a filesystem error "Freeing blocks not in
datazone - block = 18446744071529317386, count = 1" and the backup
process stopped. Trying to fix the fs with e2fsck resulted in a
completely corrupted fs. The error probably came from ext2_free_blocks(),
and because of the large number 18e19 this problem immediately looked
like some kind of integer overflow. Whereas the 4TB fs was about 1e9
blocks, the new 12TB is about 3e9 blocks. So, searching the ext2 code,
I came across the line in fs/ext2/xattr.c:745 where ext2_new_block()
is called and the resulting block number is stored in the variable block
as an int datatype. If a block with a block number greater than
INT32_MAX is returned, this variable overflows and the call to
sb_getblk() at line fs/ext2/xattr.c:750 fails, then the call to
ext2_free_blocks() produces the error.

9ac69bda79 drm/exynos: fix a possible null-pointer dereference due to data race in exynos_drm_crtc_atomic_disable()
[ Upstream commit 2e63972a2de14482d0eae1a03a73e379f1c3f44c ]

The variable crtc->state->event is often protected by the lock
crtc->dev->event_lock when is accessed. However, it is accessed as a
condition of an if statement in exynos_drm_crtc_atomic_disable() without
holding the lock:

  if (crtc->state->event && !crtc->state->active)

However, if crtc->state->event is changed to NULL by another thread right
after the conditions of the if statement is checked to be true, a
null-pointer dereference can occur in drm_crtc_send_vblank_event():

  e->pipe = pipe;

To fix this possible null-pointer dereference caused by data race, the
spin lock coverage is extended to protect the if statement as well as the
function call to drm_crtc_send_vblank_event().

During NVMeTCP Authentication a controller can trigger a kernel

a correctly sized, but zeroed Diffie Hellamn value.
mpi_cmp_ui() was detecting this if the second parameter was 0,
but 1 is passed from dh_is_pubkey_valid(). This causes the null
pointer u->d to be dereferenced towards the end of mpi_cmp_ui()

4dc0d161ce wifi: mwifiex: fix fortify warning
[ Upstream commit dcce94b80a954a8968ff29fafcfb066d6197fa9a ]

When compiling with gcc 13.1 and CONFIG_FORTIFY_SOURCE=y,
I've noticed the following:

In function ‘fortify_memcpy_chk’,
    inlined from ‘mwifiex_construct_tdls_action_frame’ at drivers/net/wireless/marvell/mwifiex/tdls.c:765:3,
    inlined from ‘mwifiex_send_tdls_action_frame’ at drivers/net/wireless/marvell/mwifiex/tdls.c:856:6:

  529 |                         __read_overflow2_field(q_size_field, size);
      |                         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The compiler actually complains on:

memmove(pos + ETH_ALEN, &mgmt->u.action.category,
	sizeof(mgmt->u.action.u.tdls_discover_resp));

and it happens because the fortification logic interprets this
as an attempt to overread 1-byte 'u.action.category' member of
'struct ieee80211_mgmt'. To silence this warning, it's enough
to pass an address of 'u.action' itself instead of an address
of its first member.

This also fixes an improper usage of 'sizeof()'. Since 'skb' is
extended with 'sizeof(mgmt->u.action.u.tdls_discover_resp) + 1'
bytes (where 1 is actually 'sizeof(mgmt->u.action.category)'),
I assume that the same number of bytes should be copied.

17059ddb17 wifi: ath9k: fix printk specifier
[ Upstream commit 061115fbfb2ce5870c9a004d68dc63138c07c782 ]

Smatch reports:

ath_pci_probe() warn: argument 4 to %lx specifier is cast from pointer
ath_ahb_probe() warn: argument 4 to %lx specifier is cast from pointer

Fix it by modifying %lx to %p in the printk format string.

Note that with this change, the pointer address will be printed as a
hashed value by default. This is appropriate because the kernel
should not leak kernel pointers to user space in an informational
message. If someone wants to see the real address for debugging
purposes, this can be achieved with the no_hash_pointers kernel option.

d228251563 hw_breakpoint: fix single-stepping when using bpf_overflow_handler
[ Upstream commit d11a69873d9a7435fe6a48531e165ab80a8b1221 ]

Arm platforms use is_default_overflow_handler() to determine if the
hw_breakpoint code should single-step over the breakpoint trigger or
let the custom handler deal with it.

Since bpf_overflow_handler() currently isn't recognized as a default
handler, attaching a BPF program to a PERF_TYPE_BREAKPOINT event causes
it to keep firing (the instruction triggering the data abort exception
is never skipped). For example:

  # bpftrace -e 'watchpoint:0x10000:4:w { print("hit") }' -c ./test
  Attaching 1 probe...
  hit
  hit
  [...]
  ^C

(./test performs a single 4-byte store to 0x10000)

This patch replaces the check with uses_default_overflow_handler(),
which accounts for the bpf_overflow_handler() case by also testing
if one of the perf_event_output functions gets invoked indirectly,
via orig_default_handler.

400e08a166 btrfs: output extra debug info if we failed to find an inline backref
[ Upstream commit 7f72f50547b7af4ddf985b07fc56600a4deba281 ]

[BUG]
Syzbot reported several warning triggered inside
lookup_inline_extent_backref().

[CAUSE]
As usual, the reproducer doesn't reliably trigger locally here, but at
least we know the WARN_ON() is triggered when an inline backref can not
be found, and it can only be triggered when @insert is true. (I.e.
inserting a new inline backref, which means the backref should already
exist)

[ENHANCEMENT]
After the WARN_ON(), dump all the parameters and the extent tree
leaf to help debug.

autofs_wait_queue structs should be freed if their wait_ctr becomes zero.
Otherwise they will be lost.

In this case an AUTOFS_IOC_EXPIRE_MULTI ioctl is done, then a new
waitqueue struct is allocated in autofs_wait(), its initial wait_ctr
equals 2. After that wait_event_killable() is interrupted (it returns
-ERESTARTSYS), so that 'wq->name.name == NULL' condition may be not
satisfied. Actually, this condition can be satisfied when
autofs_wait_release() or autofs_catatonic_mode() is called and, what is
also important, wait_ctr is decremented in those places. Upon the exit of
autofs_wait(), wait_ctr is decremented to 1. Then the unmounting process
begins: kill_sb calls autofs_catatonic_mode(), which should have freed the
waitqueues, but it only decrements its usage counter to zero which is not
a correct behaviour.

edit:imk
This description is of course not correct. The umount performed as a result
of an expire is a umount of a mount that has been automounted, it's not the
autofs mount itself. They happen independently, usually after everything
mounted within the autofs file system has been expired away. If everything
hasn't been expired away the automount daemon can still exit leaving mounts
in place. But expires done in both cases will result in a notification that
calls autofs_wait_release() with a result status. The problem case is the
summary execution of of the automount daemon. In this case any waiting
processes won't be woken up until either they are terminated or the mount
is umounted.
end edit: imk

So in catatonic mode we should free waitqueues which counter becomes zero.

edit: imk
Initially I was concerned that the calling of autofs_wait_release() and
autofs_catatonic_mode() was not mutually exclusive but that can't be the
case (obviously) because the queue entry (or entries) is removed from the
list when either of these two functions are called. Consequently the wait
entry will be freed by only one of these functions or by the woken process
in autofs_wait() depending on the order of the calls.

3030536d29 drm/amd/display: Fix a bug when searching for insert_above_mpcc
commit 3d028d5d60d516c536de1ddd3ebf3d55f3f8983b upstream.

[WHY]
Currently, when insert_plane is called with insert_above_mpcc
parameter that is equal to tree->opp_list, the function returns NULL.

[HOW]
Instead, the function should insert the plane at the top of the tree.

d4b8f380b0 kcm: Fix error handling for SOCK_DGRAM in kcm_sendmsg().
[ Upstream commit a22730b1b4bf437c6bbfdeff5feddf54be4aeada ]

syzkaller found a memory leak in kcm_sendmsg(), and commit c821a88bd720
("kcm: Fix memory leak in error path of kcm_sendmsg()") suppressed it by
updating kcm_tx_msg(head)->last_skb if partial data is copied so that the
following sendmsg() will resume from the skb.

However, we cannot know how many bytes were copied when we get the error.
Thus, we could mess up the MSG_MORE queue.

When kcm_sendmsg() fails for SOCK_DGRAM, we should purge the queue as we
do so for UDP by udp_flush_pending_frames().

Even without this change, when the error occurred, the following sendmsg()
resumed from a wrong skb and the queue was messed up.  However, we have
yet to get such a report, and only syzkaller stumbled on it.  So, this
can be changed safely.

Note this does not change SOCK_SEQPACKET behaviour.

Fixes: c821a88bd720 ("kcm: Fix memory leak in error path of kcm_sendmsg()")
Fixes: ab7ac4eb98 ("kcm: Kernel Connection Multiplexor module")
