msm: kgsl: Prevent wrap around during user address mapping
When setting svm region during the gpuobj import ioctl call for a usermem address, there is a possibility of a very large input size causing the region's 64-bit end address to wrap around. This can cause the region to incorrectly be considered valid, ultimately allowing a use after free scenario. To prevent this, detect the occurrence of a wrap and reject the import.

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

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.

drm/amdgpu: fix amdgpu_cs_p1_user_fence
commit 35588314e963938dfdcdb792c9170108399377d6 upstream. The offset is just 32bits here so this can potentially overflow if somebody specifies a large value. Instead reduce the size to calculate the last possible offset. The error handling path incorrectly drops the reference to the user fence BO resulting in potential reference count underflow.

ext4: fix rec_len verify error
commit 7fda67e8c3ab6069f75888f67958a6d30454a9f6 upstream.
With the configuration PAGE_SIZE 64k and filesystem blocksize 64k,
a problem occurred when more than 13 million files were directly created
under a directory:
EXT4-fs error (device xx): ext4_dx_csum_set:492: inode #xxxx: comm xxxxx: dir seems corrupt? Run e2fsck -D.
EXT4-fs error (device xx): ext4_dx_csum_verify:463: inode #xxxx: comm xxxxx: dir seems corrupt? Run e2fsck -D.
EXT4-fs error (device xx): dx_probe:856: inode #xxxx: block 8188: comm xxxxx: Directory index failed checksum
When enough files are created, the fake_dirent->reclen will be 0xffff.
it doesn't equal to the blocksize 65536, i.e. 0x10000.
But it is not the same condition when blocksize equals to 4k.
when enough files are created, the fake_dirent->reclen will be 0x1000.
it equals to the blocksize 4k, i.e. 0x1000.
The problem seems to be related to the limitation of the 16-bit field
when the blocksize is set to 64k.
To address this, helpers like ext4_rec_len_{from,to}_disk has already
been introduced to complete the conversion between the encoded and the
plain form of rec_len.
So fix this one by using the helper, and all the other in this file too.

tracefs: Add missing lockdown check to tracefs_create_dir()
commit 51aab5ffceb43e05119eb059048fd75765d2bc21 upstream.
The function tracefs_create_dir() was missing a lockdown check and was
called by the RV code. This gave an inconsistent behavior of this function
returning success while other tracefs functions failed. This caused the
inode being freed by the wrong kmem_cache.

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: WARNING: possible circular locking dependency detected 6.5.0-rc7-syzkaller-00024-g93f5de5f648d #0 Not tainted ------------------------------------------------------ syz-executor.2/13257 is trying to acquire lock: ffff88801835c0c0 (&delayed_node->mutex){+.+.}-{3:3}, at: __btrfs_release_delayed_node+0x9a/0xaa0 fs/btrfs/delayed-inode.c:256 but task is already holding lock: ffff88802a5ab8e8 (btrfs-tree-00){++++}-{3:3}, at: __btrfs_tree_lock+0x3c/0x2a0 fs/btrfs/locking.c:198 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #1 (btrfs-tree-00){++++}-{3:3}: __lock_release kernel/locking/lockdep.c:5475 [inline] lock_release+0x36f/0x9d0 kernel/locking/lockdep.c:5781 up_write+0x79/0x580 kernel/locking/rwsem.c:1625 btrfs_tree_unlock_rw fs/btrfs/locking.h:189 [inline] btrfs_unlock_up_safe+0x179/0x3b0 fs/btrfs/locking.c:239 search_leaf fs/btrfs/ctree.c:1986 [inline] btrfs_search_slot+0x2511/0x2f80 fs/btrfs/ctree.c:2230 btrfs_insert_empty_items+0x9c/0x180 fs/btrfs/ctree.c:4376 btrfs_insert_delayed_item fs/btrfs/delayed-inode.c:746 [inline] btrfs_insert_delayed_items fs/btrfs/delayed-inode.c:824 [inline] __btrfs_commit_inode_delayed_items+0xd24/0x2410 fs/btrfs/delayed-inode.c:1111 __btrfs_run_delayed_items+0x1db/0x430 fs/btrfs/delayed-inode.c:1153 flush_space+0x269/0xe70 fs/btrfs/space-info.c:723 btrfs_async_reclaim_metadata_space+0x106/0x350 fs/btrfs/space-info.c:1078 process_one_work+0x92c/0x12c0 kernel/workqueue.c:2600 worker_thread+0xa63/0x1210 kernel/workqueue.c:2751 kthread+0x2b8/0x350 kernel/kthread.c:389 ret_from_fork+0x2e/0x60 arch/x86/kernel/process.c:145 ret_from_fork_asm+0x11/0x20 arch/x86/entry/entry_64.S:304 -> #0 (&delayed_node->mutex){+.+.}-{3:3}: check_prev_add kernel/locking/lockdep.c:3142 [inline] check_prevs_add kernel/locking/lockdep.c:3261 [inline] validate_chain kernel/locking/lockdep.c:3876 [inline] __lock_acquire+0x39ff/0x7f70 kernel/locking/lockdep.c:5144 lock_acquire+0x1e3/0x520 kernel/locking/lockdep.c:5761 __mutex_lock_common+0x1d8/0x2530 kernel/locking/mutex.c:603 __mutex_lock kernel/locking/mutex.c:747 [inline] mutex_lock_nested+0x1b/0x20 kernel/locking/mutex.c:799 __btrfs_release_delayed_node+0x9a/0xaa0 fs/btrfs/delayed-inode.c:256 btrfs_release_delayed_node fs/btrfs/delayed-inode.c:281 [inline] __btrfs_run_delayed_items+0x2b5/0x430 fs/btrfs/delayed-inode.c:1156 btrfs_commit_transaction+0x859/0x2ff0 fs/btrfs/transaction.c:2276 btrfs_sync_file+0xf56/0x1330 fs/btrfs/file.c:1988 vfs_fsync_range fs/sync.c:188 [inline] vfs_fsync fs/sync.c:202 [inline] do_fsync fs/sync.c:212 [inline] __do_sys_fsync fs/sync.c:220 [inline] __se_sys_fsync fs/sync.c:218 [inline] __x64_sys_fsync+0x196/0x1e0 fs/sync.c:218 do_syscall_x64 arch/x86/entry/common.c:50 [inline] do_syscall_64+0x41/0xc0 arch/x86/entry/common.c:80 entry_SYSCALL_64_after_hwframe+0x63/0xcd other info that might help us debug this: Possible unsafe locking scenario: CPU0 CPU1 ---- ---- lock(btrfs-tree-00);

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].

btrfs: compare the correct fsid/metadata_uuid in btrfs_validate_super
[ Upstream commit 6bfe3959b0e7a526f5c64747801a8613f002f05a ]
The function btrfs_validate_super() should verify the metadata_uuid in
the provided superblock argument. Because, all its callers expect it to
do that.
Such as in the following stacks:
write_all_supers()
sb = fs_info->super_for_commit;
btrfs_validate_write_super(.., sb)
btrfs_validate_super(.., sb, ..)
scrub_one_super()
btrfs_validate_super(.., sb, ..)
And
check_dev_super()
btrfs_validate_super(.., sb, ..)
However, it currently verifies the fs_info::super_copy::metadata_uuid
instead. Fix this using the correct metadata_uuid in the superblock
argument.

kobject: Add sanity check for kset->kobj.ktype in kset_register()
[ 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:
[ 4453.568337] Unable to handle kernel NULL pointer dereference at \
virtual address 0000000000000028
... ...
[ 4453.810361] Call trace:
[ 4453.813062] kobject_get_ownership+0xc/0x34
[ 4453.817493] kobject_add_internal+0x98/0x274
[ 4453.822005] kset_register+0x5c/0xb4
[ 4453.825820] my_kobj_init+0x44/0x1000 [my_kset]
... ...
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.

scsi: target: iscsi: Fix buffer overflow in lio_target_nacl_info_show()
[ 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.

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.

bus: ti-sysc: Configure uart quirks for k3 SoC
[ Upstream commit 03a711d3cb83692733f865312f49e665c49de6de ] Enable the uart quirks similar to the earlier SoCs. Let's assume we are likely going to need a k3 specific quirk mask separate from the earlier SoCs, so let's not start changing the revision register mask at this point. Note that SYSC_QUIRK_LEGACY_IDLE will be needed until we can remove the need for pm_runtime_irq_safe() from 8250_omap driver.

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().

wifi: mac80211_hwsim: drop short frames
[ Upstream commit fba360a047d5eeeb9d4b7c3a9b1c8308980ce9a6 ] While technically some control frames like ACK are shorter and end after Address 1, such frames shouldn't be forwarded through wmediumd or similar userspace, so require the full 3-address header to avoid accessing invalid memory if shorter frames are passed in.

alx: fix OOB-read compiler warning
[ Upstream commit 3a198c95c95da10ad844cbeade2fe40bdf14c411 ]
The following message shows up when compiling with W=1:
In function ‘fortify_memcpy_chk’,
inlined from ‘alx_get_ethtool_stats’ at drivers/net/ethernet/atheros/alx/ethtool.c:297:2:
./include/linux/fortify-string.h:592:4: error: call to ‘__read_overflow2_field’
declared with attribute warning: detected read beyond size of field (2nd parameter);
maybe use struct_group()? [-Werror=attribute-warning]
592 | __read_overflow2_field(q_size_field, size);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In order to get alx stats altogether, alx_get_ethtool_stats() reads
beyond hw->stats.rx_ok. Fix this warning by directly copying hw->stats,
and refactor the unnecessarily complicated BUILD_BUG_ON btw.

mmc: sdhci-esdhc-imx: improve ESDHC_FLAG_ERR010450
[ Upstream commit 5ae4b0d8875caa44946e579420c7fd5740d58653 ] Errata ERR010450 only shows up if voltage is 1.8V, but if the device is supplied by 3v3 the errata can be ignored. So let's check for if quirk SDHCI_QUIRK2_NO_1_8_V is defined or not before limiting the frequency.
