------------------
From: Jann Horn <jannh@google.com>
commit 3c0da3d163eb32f1f91891efaade027fa9b245b9 upstream.
fuse_notify_store(), unlike fuse_do_readpage(), does not enable page
zeroing (because it can be used to change partial page contents).
So fuse_notify_store() must be more careful to fully initialize page
contents (including parts of the page that are beyond end-of-file)
before marking the page uptodate.
The current code can leave beyond-EOF page contents uninitialized, which
makes these uninitialized page contents visible to userspace via mmap().
This is an information leak, but only affects systems which do not
enable init-on-alloc (via CONFIG_INIT_ON_ALLOC_DEFAULT_ON=y or the
corresponding kernel command line parameter).

From: Mathias Nyman <mathias.nyman@linux.intel.com>
commit af8e119f52e9c13e556be9e03f27957554a84656 upstream.
re-enumerating full-speed devices after a failed address device command
can trigger a NULL pointer dereference.
Full-speed devices may need to reconfigure the endpoint 0 Max Packet Size
value during enumeration. Usb core calls usb_ep0_reinit() in this case,
which ends up calling xhci_configure_endpoint().
On Panther point xHC the xhci_configure_endpoint() function will
additionally check and reserve bandwidth in software. Other hosts do
this in hardware
If xHC address device command fails then a new xhci_virt_device structure
is allocated as part of re-enabling the slot, but the bandwidth table
pointers are not set up properly here.
This triggers the NULL pointer dereference the next time usb_ep0_reinit()
is called and xhci_configure_endpoint() tries to check and reserve
bandwidth

checking for bandwidth in cases like this where no actual endpoints are
added or removed, i.e. only context for default control endpoint 0 is
evaluated.

From: Haibo Xu <haibo1.xu@intel.com>
commit a21dcf0ea8566ebbe011c79d6ed08cdfea771de3 upstream.
Currently, only acpi_early_node_map[0] was initialized to NUMA_NO_NODE.
To ensure all the values were properly initialized, switch to initialize
all of them to NUMA_NO_NODE.

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Khazhismel Kumykov <khazhy@google.com>
commit 7a636b4f03af9d541205f69e373672e7b2b60a8a upstream.
If the dm_resume method is called on a device that is not suspended, the
method will suspend the device briefly, before resuming it (so that the
table will be swapped).
However, there was a bug that the return value of dm_suspended_md was not
checked. dm_suspended_md may return an error when it is interrupted by a
signal. In this case, do_resume would call dm_swap_table, which would
return -EINVAL.
This commit fixes the logic, so that error returned by dm_suspend is
checked and the resume operation is undone.

commit faada2174c08662ae98b439c69efe3e79382c538 upstream.
kmalloc is unreliable when allocating more than 8 pages of memory. It may
fail when there is plenty of free memory but the memory is fragmented.
Zdenek Kabelac observed such failure in his tests.
This commit changes kmalloc to kvmalloc - kvmalloc will fall back to
vmalloc if the large allocation fails.

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alexander Lobakin <aleksander.lobakin@intel.com>
commit a37fbe666c016fd89e4460d0ebfcea05baba46dc upstream.
The number of times yet another open coded
`BITS_TO_LONGS(nbits) * sizeof(long)` can be spotted is huge.
Some generic helper is long overdue.
Add one, bitmap_size(), but with one detail.
BITS_TO_LONGS() uses DIV_ROUND_UP(). The latter works well when both
divident and divisor are compile-time constants or when the divisor
is not a pow-of-2. When it is however, the compilers sometimes tend
to generate suboptimal code (GCC 13):
48 83 c0 3f add $0x3f,%rax
48 c1 e8 06 shr $0x6,%rax
48 8d 14 c5 00 00 00 00 lea 0x0(,%rax,8),%rdx
%BITS_PER_LONG is always a pow-2 (either 32 or 64), but GCC still does
full division of `nbits + 63` by it and then multiplication by 8.
Instead of BITS_TO_LONGS(), use ALIGN() and then divide by 8. GCC:
8d 50 3f lea 0x3f(%rax),%edx
c1 ea 03 shr $0x3,%edx
81 e2 f8 ff ff 1f and $0x1ffffff8,%edx
Now it shifts `nbits + 63` by 3 positions (IOW performs fast division
by 8) and then masks bits[2:0]. bloat-o-meter:
add/remove: 0/0 grow/shrink: 20/133 up/down: 156/-773 (-617)
Clang does it better and generates the same code before/after starting
from -O1, except that with the ALIGN() approach it uses %edx and thus
still saves some bytes:
add/remove: 0/0 grow/shrink: 9/133 up/down: 18/-538 (-520)
Note that we can't expand DIV_ROUND_UP() by adding a check and using
this approach there, as it's used in array declarations where
expressions are not allowed.
Add this helper to tools/ as well.

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Al Viro <viro@zeniv.linux.org.uk>
commit 9a2fa1472083580b6c66bdaf291f591e1170123a upstream.
copy_fd_bitmaps(new, old, count) is expected to copy the first
count/BITS_PER_LONG bits from old->full_fds_bits[] and fill
the rest with zeroes. What it does is copying enough words
(BITS_TO_LONGS(count/BITS_PER_LONG)), then memsets the rest.
That works fine, *if* all bits past the cutoff point are
clear. Otherwise we are risking garbage from the last word
we'd copied.
For most of the callers that is true - expand_fdtable() has
count equal to old->max_fds, so there's no open descriptors
past count, let alone fully occupied words in ->open_fds[],
which is what bits in ->full_fds_bits[] correspond to.
The other caller (dup_fd()) passes sane_fdtable_size(old_fdt, max_fds),
which is the smallest multiple of BITS_PER_LONG that covers all
opened descriptors below max_fds. In the common case (copying on
fork()) max_fds is ~0U, so all opened descriptors will be below
it and we are fine, by the same reasons why the call in expand_fdtable()
is safe.
Unfortunately, there is a case where max_fds is less than that
and where we might, indeed, end up with junk in ->full_fds_bits[] -
close_range(from, to, CLOSE_RANGE_UNSHARE) with
* descriptor table being currently shared
* 'to' being above the current capacity of descriptor table
* 'from' being just under some chunk of opened descriptors.
In that case we end up with observably wrong behaviour - e.g. spawn
a child with CLONE_FILES, get all descriptors in range 0..127 open,
then close_range(64, ~0U, CLOSE_RANGE_UNSHARE) and watch dup(0) ending
up with descriptor #128, despite #64 being observably not open.
The minimally invasive fix would be to deal with that in dup_fd().
If this proves to add measurable overhead, we can go that way, but
let's try to fix copy_fd_bitmaps() first.
* new helper: bitmap_copy_and_expand(to, from, bits_to_copy, size).
* make copy_fd_bitmaps() take the bitmap size in words, rather than
bits; it's 'count' argument is always a multiple of BITS_PER_LONG,
so we are not losing any information, and that way we can use the
same helper for all three bitmaps - compiler will see that count
is a multiple of BITS_PER_LONG for the large ones, so it'll generate
plain memcpy()+memset().

commit c1023f5634b9bfcbfff0dc200245309e3cde9b54 upstream.
bitmap_size() is a pretty generic name and one may want to use it for
a generic bitmap API function. At the same time, its logic is not
"generic", i.e. it's not just `nbits -> size of bitmap in bytes`
converter as it would be expected from its name.
Add the prefix 'idset_' used throughout the file where the function
resides.

bitmap_set_bits() does not start with the FS' prefix and may collide
with a new generic helper one day. It operates with the FS-specific
types, so there's no change those two could do the same thing.
Just add the prefix to exclude such possible conflict.

------------------
From: Cosmin Ratiu <cratiu@nvidia.com>
[ Upstream commit cbc796be1779c4dbc9a482c7233995e2a8b6bfb3 ]
Previously, an ethtool rx flow with no attrs would not be added to the
NIC as it has no rules to configure the hw with, but it would be
reported as successful to the caller (return code 0). This is confusing
for the user as ethtool then reports "Added rule $num", but no rule was
actually added.
This change corrects that by instead reporting these wrong rules as
-EINVAL.

[ Upstream commit e0b5127fa134fe0284d58877b6b3133939c8b3ce ]
In ssb_calc_clock_rate(), there is a potential issue where the value of
m1 could be zero due to initialization using clkfactor_f6_resolv(). This
situation raised concerns about the possibility of a division by zero
error.
We fixed it by following the suggestions provided by Larry Finger
<Larry.Finger@lwfinger.net> and Michael Büsch <m@bues.ch>. The fix
involves returning a value of 1 instead of 0 in clkfactor_f6_resolv().
This modification ensures the proper functioning of the code and
eliminates the risk of division by zero errors.

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christian Brauner <christian.brauner@ubuntu.com>
[ Upstream commit 1c5976ef0f7ad76319df748ccb99a4c7ba2ba464 ]
Currently, registering a new binary type pins the binfmt_misc
filesystem. Specifically, this means that as long as there is at least
one binary type registered the binfmt_misc filesystem survives all
umounts, i.e. the superblock is not destroyed. Meaning that a umount
followed by another mount will end up with the same superblock and the
same binary type handlers. This is a behavior we tend to discourage for
any new filesystems (apart from a few special filesystems such as e.g.
configfs or debugfs). A umount operation without the filesystem being
pinned - by e.g. someone holding a file descriptor to an open file -
should usually result in the destruction of the superblock and all
associated resources. This makes introspection easier and leads to
clearly defined, simple and clean semantics. An administrator can rely
on the fact that a umount will guarantee a clean slate making it
possible to reinitialize a filesystem. Right now all binary types would
need to be explicitly deleted before that can happen.
This allows us to remove the heavy-handed calls to simple_pin_fs() and
simple_release_fs() when creating and deleting binary types. This in
turn allows us to replace the current brittle pinning mechanism abusing
dget() which has caused a range of bugs judging from prior fixes in [2]
and [3]. The additional dget() in load_misc_binary() pins the dentry but
only does so for the sake to prevent ->evict_inode() from freeing the
node when a user removes the binary type and kill_node() is run. Which
would mean ->interpreter and ->interp_file would be freed causing a UAF.
This isn't really nicely documented nor is it very clean because it
relies on simple_pin_fs() pinning the filesystem as long as at least one
binary type exists. Otherwise it would cause load_misc_binary() to hold
on to a dentry belonging to a superblock that has been shutdown.
Replace that implicit pinning with a clean and simple per-node refcount
and get rid of the ugly dget() pinning. A similar mechanism exists for
e.g. binderfs (cf. [4]). All the cleanup work can now be done in
->evict_inode().
In a follow-up patch we will make it possible to use binfmt_misc in
sandboxes. We will use the cleaner semantics where a umount for the
filesystem will cause the superblock and all resources to be
deallocated. In preparation for this apply the same semantics to the
initial binfmt_misc mount. Note, that this is a user-visible change and
as such a uapi change but one that we can reasonably risk. We've
discussed this in earlier versions of this patchset (cf. [1]).
The main user and provider of binfmt_misc is systemd. Systemd provides
binfmt_misc via autofs since it is configurable as a kernel module and
is used by a few exotic packages and users. As such a binfmt_misc mount
is triggered when /proc/sys/fs/binfmt_misc is accessed and is only
provided on demand. Other autofs on demand filesystems include EFI ESP
which systemd umounts if the mountpoint stays idle for a certain amount
of time. This doesn't apply to the binfmt_misc autofs mount which isn't
touched once it is mounted meaning this change can't accidently wipe
binary type handlers without someone having explicitly unmounted
binfmt_misc. After speaking to systemd folks they don't expect this
change to affect them.
In line with our general policy, if we see a regression for systemd or
other users with this change we will switch back to the old behavior for
the initial binfmt_misc mount and have binary types pin the filesystem
again. But while we touch this code let's take the chance and let's
improve on the status quo.

From: Mike Christie <michael.christie@oracle.com>
[ Upstream commit 0b149cee836aa53989ea089af1cb9d90d7c6ac9e ]
If scsi_execute_cmd returns < 0, it doesn't initialize the sshdr, so we
shouldn't access the sshdr. If it returns 0, then the cmd executed
successfully, so there is no need to check the sshdr. This has us access
the sshdr when we get a return value > 0.

From: Miri Korenblit <miriam.rachel.korenblit@intel.com>
[ Upstream commit 3c6a0b1f0add72e7f522bc9145222b86d0a7712a ]
In RFKILL we first set the RFKILL bit, then we abort scan
(if one exists) by waiting for the notification from FW
and notifying mac80211. And then we stop the device.
But in case we have a scan ongoing in the period of time between
rfkill on and before the device is stopped - we will not wait for the
FW notification because of the iwl_mvm_is_radio_killed() condition,
and then the scan_status and uid_status are misconfigured,
(scan_status is cleared but uid_status not)
and when the notification suddenly arrives (before stopping the device)
we will get into the assert about scan_status and uid_status mismatch.
Fix this by waiting for FW notif when rfkill is on but the device isn't
disabled yet.

From: Jan Kara <jack@suse.cz>
[ Upstream commit 249f374eb9b6b969c64212dd860cc1439674c4a8 ]
dqget() checks whether dquot->dq_sb is set when returning it using
BUG_ON. Firstly this doesn't work as an invalidation check for quite
some time (we release dquot with dq_sb set these days), secondly using
BUG_ON is quite harsh. Use WARN_ON_ONCE and check whether dquot is still
hashed instead.

From: Max Filippov <jcmvbkbc@gmail.com>
[ Upstream commit 15fd1dc3dadb4268207fa6797e753541aca09a2a ]
Static FDPIC executable may get an executable stack even when it has
non-executable GNU_STACK segment. This happens when STACK segment has rw
permissions, but does not specify stack size. In that case FDPIC loader
uses permissions of the interpreter's stack, and for static executables
with no interpreter it results in choosing the arch-default permissions
for the stack.
Fix that by using the interpreter's properties only when the interpreter
is actually used.

'disk->private_data' is set to mddev in md_alloc() and never set to NULL,
and users need to open mddev before submitting ioctl. So mddev must not
have been freed during ioctl, and there is no need to check mddev here.

[ Upstream commit 69b0194ccec033c208b071e019032c1919c2822d ]
simple_malloc() will return NULL when there is not enough memory left.
Check pointer 'new' before using it to copy the old data.

From: Michael Ellerman <mpe@ellerman.id.au>
[ Upstream commit f2d5bccaca3e8c09c9b9c8485375f7bdbb2631d2 ]
simple_realloc() frees the original buffer (ptr) even if the
reallocation failed.
Fix it to behave like standard realloc() and only free the original
buffer if the reallocation succeeded.

[ Upstream commit f40a3ea94881f668084f68f6b9931486b1606db0 ]
The BUG_ON is deep in the qgroup code where we can expect that it
exists. A NULL pointer would cause a crash.
It was added long ago in 550d7a2ed5db35 ("btrfs: qgroup: Add new qgroup
calculation function btrfs_qgroup_account_extents()."). It maybe made
sense back then as the quota enable/disable state machine was not that
robust as it is nowadays, so we can just delete it.

If pnfsd_update_layout() is called on a file for which recovery has
failed it will enter a tight infinite loop.
NFS_LAYOUT_INVALID_STID will be set, nfs4_select_rw_stateid() will
return -EIO, and nfs4_schedule_stateid_recovery() will do nothing, so
nfs4_client_recover_expired_lease() will not wait. So the code will
loop indefinitely.
Break the loop by testing the validity of the open stateid at the top of
the loop.

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Oreoluwa Babatunde <quic_obabatun@quicinc.com>
[ Upstream commit 7b432bf376c9c198a7ff48f1ed14a14c0ffbe1fe ]
The unflatten_and_copy_device_tree() function contains a call to
memblock_alloc(). This means that memblock is allocating memory before
any of the reserved memory regions are set aside in the setup_memory()
function which calls early_init_fdt_scan_reserved_mem(). Therefore,
there is a possibility for memblock to allocate from any of the
reserved memory regions.
Hence, move the call to setup_memory() to be earlier in the init
sequence so that the reserved memory regions are set aside before any
allocations are done using memblock.

From: Krishna Kurapati <quic_kriskura@quicinc.com>
[ Upstream commit 89d7f962994604a3e3d480832788d06179abefc5 ]
On some SoC's like SA8295P where the tertiary controller is host-only
capable, GEVTADDRHI/LO, GEVTSIZ, GEVTCOUNT registers are not accessible.
Trying to access them leads to a crash.
For DRD/Peripheral supported controllers, event buffer setup is done
again in gadget_pullup. Skip setup or cleanup of event buffers if
controller is host-only capable.

From: Sagi Grimberg <sagi@grimberg.me>
[ Upstream commit 73964c1d07c054376f1b32a62548571795159148 ]
It is possible that the host connected and saw a cm established
event and started sending nvme capsules on the qp, however the
ctrl did not yet see an established event. This is why the
rsp_wait_list exists (for async handling of these cmds, we move
them to a pending list).
Furthermore, it is possible that the ctrl cm times out, resulting
in a connect-error cm event. in this case we hit a bad deref [1]
because in nvmet_rdma_free_rsps we assume that all the responses
are in the free list.
We are freeing the cmds array anyways, so don't even bother to
remove the rsp from the free_list. It is also guaranteed that we
are not racing anything when we are releasing the queue so no
other context accessing this array should be running.

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Phil Chang <phil.chang@mediatek.com>
[ Upstream commit 5a830bbce3af16833fe0092dec47b6dd30279825 ]
The hrtimer function callback must not be NULL. It has to be specified by
the call side but it is not validated by the hrtimer code. When a hrtimer
is queued without a function callback, the kernel crashes with a null
pointer dereference when trying to execute the callback in __run_hrtimer().
Introduce a validation before queuing the hrtimer in
hrtimer_start_range_ns().

commit 3a3be7ff9224f424e485287b54be00d2c6bd9c40 upstream.
syzbot/KMSAN reported use of uninit-value in get_dev_xmit() [1]
We must make sure the IPv4 or Ipv6 header is pulled in skb->head
before accessing fields in them.
Use pskb_inet_may_pull() to fix this issue.

From: Tetsuo Handa <penguin-kernel@i-love.sakura.ne.jp>
commit 37ae5a0f5287a52cf51242e76ccf198d02ffe495 upstream.
Since lo_simple_ioctl(LOOP_SET_BLOCK_SIZE) and ioctl(NBD_SET_BLKSIZE) pass
user-controlled "unsigned long arg" to blk_validate_block_size(),
"unsigned long" should be used for validation.

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
[ Upstream commit 116523c8fac05d1d26f748fee7919a4ec5df67ea ]
Change that introduced the use of __check_timeout did not account for
link types properly, it always assumes ACL_LINK is used thus causing
hdev->acl_last_tx to be used even in case of LE_LINK and then again
uses ACL_LINK with hci_link_tx_to.
To fix this __check_timeout now takes the link type as parameter and
then procedure to use the right last_tx based on the link type and pass
it to hci_link_tx_to.

1. Thread A builds a skb with MSG_MORE and sets kcm->seq_skb.
2. Thread A resumes building skb from kcm->seq_skb but is blocked
by sk_stream_wait_memory()
3. Thread B calls sendmsg() concurrently, finishes building kcm->seq_skb
and puts the skb to the write queue
4. Thread A faces an error and finally frees skb that is already in the
write queue
5. kcm_release() does double-free the skb in the write queue
When a thread is building a MSG_MORE skb, another thread must not touch it.
Let's add a per-sk mutex and serialise kcm_sendmsg().

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
[ Upstream commit a0b39e2dc7017ac667b70bdeee5293e410fab2fb ]
nft_counter_reset() resets the counter by subtracting the previously
retrieved value from the counter. This is a write operation on the
counter and as such it requires to be performed with a write sequence of
nft_counter_seq to serialize against its possible reader.
Update the packets/ bytes within write-sequence of nft_counter_seq.
Fixes: d84701ecbcd6a ("netfilter: nft_counter: rework atomic dump and reset")

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Dumazet <edumazet@google.com>
[ Upstream commit faa389b2fbaaec7fd27a390b4896139f9da662e3 ]
syzbot reported an UAF in ip6_send_skb() [1]
After ip6_local_out() has returned, we no longer can safely
dereference rt, unless we hold rcu_read_lock().
A similar issue has been fixed in commit
a688caa34beb ("ipv6: take rcu lock in rawv6_send_hdrinc()")
Another potential issue in ip6_finish_output2() is handled in a
separate patch.

[ Upstream commit 4ae738dfef2c0323752ab81786e2d298c9939321 ]
If promiscuous mode is disabled when there are fewer than four multicast
addresses, then it will not be reflected in the hardware. Fix this by
always clearing the promiscuous mode flag even when we program multicast
addresses.

------------------
From: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
[ Upstream commit df24373435f5899a2a98b7d377479c8d4376613b ]
DPU debugging macros need to be converted to a proper drm_debug_*
macros, however this is a going an intrusive patch, not suitable for a
fix. Wire DPU_DEBUG and DPU_DEBUG_DRIVER to always use DRM_DEBUG_DRIVER
to make sure that DPU debugging messages always end up in the drm debug
messages and are controlled via the usual drm.debug mask.
I don't think that it is a good idea for a generic DPU_DEBUG macro to be
tied to DRM_UT_KMS. It is used to report a debug message from driver, so by
default it should go to the DRM_UT_DRIVER channel. While refactoring
debug macros later on we might end up with particular messages going to
ATOMIC or KMS, but DRIVER should be the default.

------------------
From: Jason Gerecke <jason.gerecke@wacom.com>
commit 1b8f9c1fb464968a5b18d3acc1da8c00bad24fad upstream.
The Wacom driver maps the HID_DG_TWIST usage to ABS_Z (rather than ABS_RZ)
for historic reasons. When the code to support twist was introduced in
commit 50066a042da5 ("HID: wacom: generic: Add support for height, tilt,
and twist usages"), we were careful to write it in such a way that it had
HID calculate the resolution of the twist axis assuming ABS_RZ instead
(so that we would get correct angular behavior). This was broken with
the introduction of commit 08a46b4190d3 ("HID: wacom: Set a default
resolution for older tablets"), which moved the resolution calculation
to occur *before* the adjustment from ABS_Z to ABS_RZ occurred.
This commit moves the calculation of resolution after the point that
we are finished setting things up for its proper use.

It is done everywhere in cxgb4 code, e.g. in is_filter_exact_match()
There is no reason it should not be done here

From: Ben Whitten <ben.whitten@gmail.com>
commit 6275c7bc8dd07644ea8142a1773d826800f0f3f7 upstream.
Fix a race condition if the clock provider comes up after mmc is probed,
this causes mmc to fail without retrying.
When given the DEFER error from the clk source, pass it on up the chain.

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Iwai <tiwai@suse.de>
commit ccbfcac05866ebe6eb3bc6d07b51d4ed4fcde436 upstream.
The recent addition of a sanity check for a too low start tick time
seems breaking some applications that uses aloop with a certain slave
timer setup. They may have the initial resolution 0, hence it's
treated as if it were a too low value.
Relax and skip the check for the slave timer instance for addressing
the regression.

From: Lee, Chun-Yi <joeyli.kernel@gmail.com>
commit 9c33663af9ad115f90c076a1828129a3fbadea98 upstream.

accessing hci_uart->proto. It fixes the race condition in
hci_uart_tty_ioctl() between HCIUARTSETPROTO and HCIUARTGETPROTO.

From: Alexander Lobakin <aleksander.lobakin@intel.com>
commit 10a04ff09bcc39e0044190ffe9f00f998f13647c upstream.
Currently, tools have *ALIGN*() macros scattered across the unrelated
headers, as there are only 3 of them and they were added separately
each time on an as-needed basis.
Anyway, let's make it more consistent with the kernel headers and allow
using those macros outside of the mentioned headers. Create
<linux/align.h> inside the tools/ folder and include it where needed.

commit 27ec3c57fcadb43c79ed05b2ea31bc18c72d798a upstream.
mwifiex_band_2ghz and mwifiex_band_5ghz are statically allocated, but
used and modified in driver instances. Duplicate them before using
them in driver instances so that different driver instances do not
influence each other.
This was observed on a board which has one PCIe and one SDIO mwifiex
adapter. It blew up in mwifiex_setup_ht_caps(). This was called with
the statically allocated struct which is modified in this function.

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mikulas Patocka <mpatocka@redhat.com>
commit 1e1fd567d32fcf7544c6e09e0e5bc6c650da6e23 upstream.
This commit changes device mapper, so that it returns -ERESTARTSYS
instead of -EINTR when it is interrupted by a signal (so that the ioctl
can be restarted).
The manpage signal(7) says that the ioctl function should be restarted if
the signal was handled with SA_RESTART.

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Damien Le Moal <dlemoal@kernel.org>
commit 82dbb57ac8d06dfe8227ba9ab11a49de2b475ae5 upstream.
Some firmware versions of the 9600 series SAS HBA byte-swap the REPORT
ZONES command reply buffer from ATA-ZAC devices by directly accessing the
buffer in the host memory. This does not respect the default command DMA
direction and causes IOMMU page faults on architectures with an IOMMU
enforcing write-only mappings for DMA_FROM_DEVICE DMA driection (e.g. AMD
hosts).

Avoid such issue by always mapping the buffer of REPORT ZONES commands
using DMA_BIDIRECTIONAL (read+write IOMMU mapping). This is done by
introducing the helper function _base_scsi_dma_map() and using this helper
in _base_build_sg_scmd() and _base_build_sg_scmd_ieee() instead of calling
directly scsi_dma_map().

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Long Li <leo.lilong@huawei.com>
The locks_remove_posix() function in fcntl_setlk/fcntl_setlk64 is designed
to reliably remove locks when an fcntl/close race is detected. However, it
was passing in the wrong filelock owner, it looks like a mistake and
resulting in a failure to remove locks. More critically, if the lock
removal fails, it could lead to a uaf issue while traversing the locks.
This problem occurs only in the 4.19/5.4 stable version.
Fixes: a561145f3ae9 ("filelock: Fix fcntl/close race recovery compat path")

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ricardo Ribalda <ribalda@chromium.org>
commit 8676a5e796fa18f55897ca36a94b2adf7f73ebd1 upstream.
The function uvc_video_clock_update() supports a single SOF overflow. Or
in other words, the maximum difference between the first ant the last
timestamp can be 4096 ticks or 4.096 seconds.
This results in a maximum value for y2 of: 0x12FBECA00, that overflows
32bits.
y2 = (u32)ktime_to_ns(ktime_sub(last->host_time, first->host_time)) + y1;
Extend the size of y2 to u64 to support all its values.

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Niklas Cassel <cassel@kernel.org>
commit 5d92c7c566dc76d96e0e19e481d926bbe6631c1e upstream.
If the ata_port_alloc() call in ata_host_alloc() fails,
ata_host_release() will get called.
However, the code in ata_host_release() tries to free ata_port struct
members unconditionally, which can lead to the following:

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chen Ridong <chenridong@huawei.com>
commit 1be59c97c83ccd67a519d8a49486b3a8a73ca28a upstream.
An UAF can happen when /proc/cpuset is read as reported in [1].
This can be reproduced by the following methods:
1.add an mdelay(1000) before acquiring the cgroup_lock In the
cgroup_path_ns function.
2.$cat /proc/<pid>/cpuset repeatly.
3.$mount -t cgroup -o cpuset cpuset /sys/fs/cgroup/cpuset/
$umount /sys/fs/cgroup/cpuset/ repeatly.
The race that cause this bug can be shown as below:
(umount) | (cat /proc/<pid>/cpuset)
css_release | proc_cpuset_show
css_release_work_fn | css = task_get_css(tsk, cpuset_cgrp_id);
css_free_rwork_fn | cgroup_path_ns(css->cgroup, ...);
cgroup_destroy_root | mutex_lock(&cgroup_mutex);
rebind_subsystems |
cgroup_free_root |
| // cgrp was freed, UAF
| cgroup_path_ns_locked(cgrp,..);
When the cpuset is initialized, the root node top_cpuset.css.cgrp
will point to &cgrp_dfl_root.cgrp. In cgroup v1, the mount operation will
allocate cgroup_root, and top_cpuset.css.cgrp will point to the allocated
&cgroup_root.cgrp. When the umount operation is executed,
top_cpuset.css.cgrp will be rebound to &cgrp_dfl_root.cgrp.
The problem is that when rebinding to cgrp_dfl_root, there are cases
where the cgroup_root allocated by setting up the root for cgroup v1
is cached. This could lead to a Use-After-Free (UAF) if it is
subsequently freed. The descendant cgroups of cgroup v1 can only be
freed after the css is released. However, the css of the root will never
be released, yet the cgroup_root should be freed when it is unmounted.
This means that obtaining a reference to the css of the root does
not guarantee that css.cgrp->root will not be freed.
Fix this problem by using rcu_read_lock in proc_cpuset_show().
As cgroup_root is kfree_rcu after commit d23b5c577715
("cgroup: Make operations on the cgroup root_list RCU safe"),
css->cgroup won't be freed during the critical section.
To call cgroup_path_ns_locked, css_set_lock is needed, so it is safe to
replace task_get_css with task_css.

------------------
From: Vasily Averin <vvs@virtuozzo.com>
commit 18319498fdd4cdf8c1c2c48cd432863b1f915d6f upstream.
When user creates IPC objects it forces kernel to allocate memory for
these long-living objects.
It makes sense to account them to restrict the host's memory consumption
from inside the memcg-limited container.
This patch enables accounting for IPC shared memory segments, messages
semaphores and semaphore's undo lists.

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Helge Deller <deller@gmx.de>
commit e64242caef18b4a5840b0e7a9bff37abd4f4f933 upstream.
We need to prevent that users configure a screen size which is smaller than the
currently selected font size. Otherwise rendering chars on the screen will
access memory outside the graphics memory region.
This patch adds a new function fbcon_modechange_possible() which
implements this check and which later may be extended with other checks
if necessary. The new function is called from the FBIOPUT_VSCREENINFO
ioctl handler in fbmem.c, which will return -EINVAL if userspace asked
for a too small screen size.

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Allison Henderson <allison.henderson@oracle.com>
commit f1acf1ac84d2ae97b7889b87223c1064df850069 upstream.
Functions rds_still_queued and rds_clear_recv_queue lock a given socket
in order to safely iterate over the incoming rds messages. However
calling rds_inc_put while under this lock creates a potential deadlock.
rds_inc_put may eventually call rds_message_purge, which will lock
m_rs_lock. This is the incorrect locking order since m_rs_lock is
meant to be locked before the socket. To fix this, we move the message
item to a local list or variable that wont need rs_recv_lock protection.
Then we can safely call rds_inc_put on any item stored locally after
rs_recv_lock is released.
Fixes: bdbe6fbc6a2f ("RDS: recv.c")

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Matthew Wilcox (Oracle) <willy@infradead.org>
commit af73483f4e8b6f5c68c9aa63257bdd929a9c194a upstream.
The IDA usually detects double-frees, but that detection failed to
consider the case when there are no nearby IDs allocated and so we have a
NULL bitmap rather than simply having a clear bit. Add some tests to the
test-suite to be sure we don't inadvertently reintroduce this problem.
Unfortunately they're quite noisy so include a message to disregard
the warnings.

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Dumazet <edumazet@google.com>
commit 23d05d563b7e7b0314e65c8e882bc27eac2da8e7 upstream.
Once again syzbot is able to crash the kernel in skb_segment() [1]
GSO_BY_FRAGS is a forbidden value, but unfortunately the following
computation in skb_segment() can reach it quite easily :
mss = mss * partial_segs;
65535 = 3 * 5 * 17 * 257, so many initial values of mss can lead to
a bad final result.
Make sure to limit segmentation so that the new mss value is smaller
than GSO_BY_FRAGS.

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
commit ab8d66d132bc8f1992d3eb6cab8d32dda6733c84 upstream.
Two bitmasks in 'struct sdw_slave_prop' - 'source_ports' and
'sink_ports' - define which ports to program in
sdw_program_slave_port_params(). The masks are used to get the
appropriate data port properties ('struct sdw_get_slave_dpn_prop') from
an array.
Bitmasks can be non-continuous or can start from index different than 0,
thus when looking for matching port property for given port, we must
iterate over mask bits, not from 0 up to number of ports.
This fixes allocation and programming slave ports, when a source or sink
masks start from further index.

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Cong Wang <cong.wang@bytedance.com>
[ Upstream commit defd8b3c37b0f9cb3e0f60f47d3d78d459d57fda ]
When sockfd_lookup() fails, gtp_encap_enable_socket() returns a
NULL pointer, but its callers only check for error pointers thus miss
the NULL pointer case.
Fix it by returning an error pointer with the error code carried from
sockfd_lookup().
(I found this bug during code inspection.)

From: Eric Dumazet <edumazet@google.com>
[ Upstream commit 0870b0d8b393dde53106678a1e2cec9dfa52f9b7 ]
Typically, busy-polling durations are below 100 usec.
When/if the busy-poller thread migrates to another cpu,
local_clock() can be off by +/-2msec or more for small
values of HZ, depending on the platform.
Use ktimer_get_ns() to ensure deterministic behavior,
which is the whole point of busy-polling.

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Selvarasu Ganesan <selvarasu.g@samsung.com>
commit 14e497183df28c006603cc67fd3797a537eef7b9 upstream.
This commit addresses an issue where the USB core could access an
invalid event buffer address during runtime suspend, potentially causing
SMMU faults and other memory issues in Exynos platforms. The problem
arises from the following sequence.
1. In dwc3_gadget_suspend, there is a chance of a timeout when
moving the USB core to the halt state after clearing the
run/stop bit by software.
2. In dwc3_core_exit, the event buffer is cleared regardless of
the USB core's status, which may lead to an SMMU faults and
other memory issues. if the USB core tries to access the event
buffer address.
To prevent this hardware quirk on Exynos platforms, this commit ensures
that the event buffer address is not cleared by software when the USB
core is active during runtime suspend by checking its status before
clearing the buffer address.

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
commit ddfcfeba891064b88bb844208b43bef2ef970f0c upstream.
The probe function never performs any paltform device allocation, thus
error path "undo_platform_dev_alloc" is entirely bogus. It drops the
reference count from the platform device being probed. If error path is
triggered, this will lead to unbalanced device reference counts and
premature release of device resources, thus possible use-after-free when
releasing remaining devm-managed resources.

------------------
From: Zijun Hu <quic_zijuhu@quicinc.com>
commit 3a8839bbb86da7968a792123ed2296d063871a52 upstream.
Device attribute group @usb3_hardware_lpm_attr_group is merged by
add_power_attributes(), but it is not unmerged explicitly, fixed by
unmerging it in remove_power_attributes().

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ben Hutchings <benh@debian.org>
[ Upstream commit 919ddf8336f0b84c0453bac583808c9f165a85c2 ]
aac_probe_one() calls hardware-specific init functions through the
aac_driver_ident::init pointer, all of which eventually call down to
aac_init_adapter().
If aac_init_adapter() fails after allocating memory for aac_dev::queues,
it frees the memory but does not clear that member.
After the hardware-specific init function returns an error,
aac_probe_one() goes down an error path that frees the memory pointed to
by aac_dev::queues, resulting.in a double-free.

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Vasily Averin <vvs@virtuozzo.com>
commit 6a4746ba06191e23d30230738e94334b26590a8a upstream.
Linus proposes to revert an accounting for sops objects in
do_semtimedop() because it's really just a temporary buffer
for a single semtimedop() system call.
This object can consume up to 2 pages, syscall is sleeping
one, size and duration can be controlled by user, and this
allocation can be repeated by many thread at the same time.
However Shakeel Butt pointed that there are much more popular
objects with the same life time and similar memory
consumption, the accounting of which was decided to be
rejected for performance reasons.
Considering at least 2 pages for task_struct and 2 pages for
the kernel stack, a back of the envelope calculation gives a
footprint amplification of <1.5 so this temporal buffer can be
safely ignored.
The factor would IMO be interesting if it was >> 2 (from the
PoV of excessive (ab)use, fine-grained accounting seems to be
currently unfeasible due to performance impact).

Apart from Powerpc build regressions we have noticed s390 build regression.
The S390 defconfig builds failed on Linux stable-rc 4.19.321-rc1 due to
following build warnings / errors with clang-18 and gcc-12.
This is a same problem on current stable-rc review on
- 4.19.321-rc1 review
In the case of stable-rc linux-4.19.y
Reported-by: Linux Kernel Functional Testing <lkft@linaro.org>
Following two commits have been added on 4.19.321-rc1.
-------
s390/cio: rename bitmap_size() -> idset_bitmap_size()
commit c1023f5634b9bfcbfff0dc200245309e3cde9b54 upstream.
bitmap: introduce generic optimized bitmap_size()
commit a37fbe666c016fd89e4460d0ebfcea05baba46dc upstream.

Odd, this should have also shown up in your 5.4.y builds too.
I'll go drop this from both trees now, thanks.

Nope, I need it there, I'll go add some helper functions to make this
work, thanks.

Build fails on our infrastructure.

Looked at the commits:
This commit 993a20bf6225c: ("tools: move alignment-related macros to new
<linux/align.h>") is causing that perf build to fail.
Solution is not to drop this patch as this is probably pulled in to
support bitmap_size() macros in these commits(which are also part of
this release):
6fbe5a3920f48 fix bitmap corruption on close_range() with
CLOSE_RANGE_UNSHARE
ef9ebc42c10f8 bitmap: introduce generic optimized bitmap_size()
Applying the below diff, helps the perf build to pass: I think we should
fold this into: commit 993a20bf6225c: ("tools: move alignment-related
macros to new <linux/align.h>")
diff --git a/tools/include/linux/align.h b/tools/include/linux/align.h

Change now made, thanks.

Are people building perf for arm on 4.19.y? If so, wow, this thing is
about to go end-of-life any week now, and I would be amazed if it built
at all anymore as I can't get perf to build on _ANY_ lts kernel these
days.
Anyway, I'll make this change and if any arm build fixes want to show
up, I'll be glad to take them.
thanks,
