This patch only affects 32bit systems. There are several integer
overflows bugs here but only the "sizeof(u32) * num_syncobj"
multiplication is a problem at runtime. (The last lines of this patch).
These variables are u32 variables that come from the user. The issue
is the multiplications can overflow leading to us allocating a smaller
buffer than intended. For the first couple integer overflows, the
syncobj_handles = memdup_user() allocation is immediately followed by
a kmalloc_array():
syncobj = kmalloc_array(num_syncobj_handles, sizeof(*syncobj), GFP_KERNEL);
In that situation the kmalloc_array() works as a bounds check and we
haven't accessed the syncobj_handlesp[] array yet so the integer overflow
is harmless.
But the "num_syncobj" multiplication doesn't have that and the integer
overflow could lead to an out of bounds access.

This patch updates the cleaner shader, which is responsible for
initializing GPU resources such as Local Data Share (LDS), Vector
General Purpose Registers (VGPRs), and Scalar General Purpose Registers
(SGPRs). Changes include adjustments to register clearing and shader
configuration.
- Updated GPU resource initialization addresses in the cleaner shader
from `be803080` to `be803000`.
- Simplified the logic in the SGPR clearing section, ensuring all SGPRs
are set to zero.

This commit doesn't fix any bug, it is just code cleanup. Use the
function format_dev_t instead of sprintf, because format_dev_t does the
same thing.
Remove the useless memset call.
An unsigned integer can take at most 10 digits, so extend the array size
to 22. (note that because the range of minor and major numbers is limited,
the size 16 could not be exceeded, thus this function couldn't write
beyond string end)

If some of the arguments "check_at_most_once", "ignore_zero_blocks",
"use_fec_from_device", "root_hash_sig_key_desc" were specified more than
once on the target line, a memory leak would happen.
This commit fixes the memory leak. It also fixes error handling in
verity_verify_sig_parse_opt_args.

There's a tiny race condition in dm-mirror. The functions queue_bio and
write_callback grab a spinlock, add a bio to the list, drop the spinlock
and wake up the mirrord thread that processes bios in the list.
It may be possible that the mirrord thread processes the bio just after
spin_unlock_irqrestore is called, before wakeup_mirrord. This spurious
wake-up is normally harmless, however if the device mapper device is
unloaded just after the bio was processed, it may be possible that
wakeup_mirrord(ms) uses invalid "ms" pointer.
Fix this bug by moving wakeup_mirrord inside the spinlock.

Get rid of the crit lock.
That frees us from the error prone logic of try_locks.
Thanks to netdev_lock() by Jakub it is now easy, and in most cases we were
protected by it already - replace crit lock by netdev lock when it was not
the case.
Lockdep reports that we should cancel the work under crit_lock [splat1],
and that was the scheme we have mostly followed since [1] by Slawomir.
But when that is done we still got into deadlocks [splat2]. So instead
we should look at the bigger problem, namely "weird locking/scheduling"
of the iavf. The first step to fix that is to remove the crit lock.
I will followup with a -next series that simplifies scheduling/tasks.
Cancel the work without netdev lock (weird unlock+lock scheme),
to fix the [splat2] (which would be totally ugly if we would kept
the crit lock).
Extend protected part of iavf_watchdog_task() to include scheduling
more work.
Note that the removed comment in iavf_reset_task() was misplaced,
it belonged to inside of the removed if condition, so it's gone now.
[splat1] - w/o this patch - The deadlock during VF removal:
WARNING: possible circular locking dependency detected
sh/3825 is trying to acquire lock:

Fix an obvious violation of lock ordering.
Jakub's [1] added netdev_lock() call that is wrong ordered wrt RTNL,
but the Fixes tag points to crit_lock being wrongly placed (by lockdep
standards).
Actual reason we got it wrong is dated back to critical section managed by
pure flag checks, which is with us since the very beginning.

Upon error along the TCP data_ready event path, we have
the following chain of calls:
strp_data_ready()
ovpn_tcp_rcv()
ovpn_peer_del()
ovpn_socket_release()
Since strp_data_ready() may be invoked from softirq context, and
ovpn_socket_release() may sleep, the above sequence may cause a
sleep in atomic context like the following:

Modules linked in: ovpn(O)
This happens because the peer deletion operation reaches
ovpn_socket_release() while ovpn_sock->sock (struct socket *)
and its sk member (struct sock *) are still both valid.
Here synchronize_rcu() is invoked, after which ovpn_sock->sock->sk
becomes NULL, due to the concurrent socket closing triggered
from userspace.
After having invoked synchronize_rcu(), ovpn_socket_release() will
attempt dereferencing ovpn_sock->sock->sk, triggering the crash
reported above.
The reason for accessing sk is that we need to retrieve its
protocol and continue the cleanup routine accordingly.
This crash can be easily produced by running openvpn userspace in
client mode with `--keepalive 10 20`, while entirely omitting this
option on the server side.
After 20 seconds ovpn will assume the peer (server) to be dead,
will start removing it and will notify userspace. The latter will
receive the notification and close the transport socket, thus
triggering the crash.
To fix the race condition for good, we need to refactor struct ovpn_socket.
Since ovpn is always only interested in the sock->sk member (struct sock *)
we can directly hold a reference to it, raher than accessing it via
its struct socket container.
This means changing "struct socket *ovpn_socket->sock" to
"struct sock *ovpn_socket->sk".
While acquiring a reference to sk, we can increase its refcounter
without affecting the socket close()/destroy() notification
(which we rely on when userspace closes a socket we are using).
By increasing sk's refcounter we know we can dereference it
in ovpn_socket_release() without incurring in any race condition
anymore.
ovpn_socket_release() will ultimately decrease the reference
counter.

When deconfiguring a UDP-tunnel from a socket, we cannot
call setup_udp_tunnel_sock() with an empty config, because
this helper is expected to be invoked only during setup.
Get rid of the call to setup_udp_tunnel_sock() and just
revert what it did during socket initialization..
Note that the global udp_encap_needed_key and the GRO state
are left untouched: udp_destroy_socket() will eventually
take care of them.

Commit 3d010c8031e3 ("udp: do not accept non-tunnel GSO skbs landing
in a tunnel") added checks in linux stack to not accept non-tunnel
GRO packets landing in a tunnel. This exposed an issue in vmxnet3
which was not correctly reporting GRO packets for tunnel packets.
This patch fixes this issue by setting correct GSO type for the
tunnel packets.
Currently, vmxnet3 does not support reporting inner fields for LRO
tunnel packets. The issue is not seen for egress drivers that do not
use skb inner fields. The workaround is to enable tnl-segmentation
offload on the egress interfaces if the driver supports it. This
problem pre-exists this patch fix and can be addressed as a separate
future patch.

The j721e driver has a single platform driver that can be built-in or a
loadable module, but it calls two separate backend drivers depending on
whether it is a host or endpoint.
If the two modes are not the same, we can end up with a situation where the
built-in pci-j721e driver tries to call the modular host or endpoint
driver, which causes a link failure:
ld.lld-21: error: undefined symbol: cdns_pcie_ep_setup
>>> referenced by pci-j721e.c
>>> drivers/pci/controller/cadence/pci-j721e.o:(j721e_pcie_probe) in archive vmlinux.a
ld.lld-21: error: undefined symbol: cdns_pcie_host_setup
>>> referenced by pci-j721e.c
>>> drivers/pci/controller/cadence/pci-j721e.o:(j721e_pcie_probe) in archive vmlinux.a
Rework the dependencies so that the 'select' is done by the common Kconfig
symbol, based on which of the two are enabled. Effectively this means that
having one built-in makes the other either built-in or disabled, but all
configurations will now build.

No need to split the line in __pci_setup_bridge() as it is way shorter
than the limit.

Pull MTD updates from Miquel Raynal:
"A big core MTD change is the introduction of a new class to always
register a master device. This is a problem that has been there
forever: the "master" device was not always present depending on a
number of heuristics such as the presence of fixed partitions and the
absence of a Kconfig symbol to force its presence. This was a problem
for runtime PM operations which might not have the "master" device
available in all situation.
The SPI NAND subsystem has seen the introduction of DTR operations
(the equivalent of DDR transfers), which involved quite a few
preparation patches for clarifying macro names.
In the raw NAND subsystem, the brcmnand driver has been "fixed" for
old legacy SoCs with an update of the ->exec_op() hook, there has been
the introduction of a new controller driver named Loongson-1, and the
Qualcomm driver has received quite a few misc fixes as well as a new
compatible.
Finally, Macornix SPI NOR entries have been cleaned-up and some SFDP
table fixups for Macronix MX25L3255E have been merged.
Aside from this, there is the usual load of misc improvement, fixes,
and yaml conversion"
