Sili Luo reported a race in nfc_llcp_sock_get(), leading to UAF.
Getting a reference on the socket found in a lookup while
holding a lock should happen before releasing the lock.
nfc_llcp_sock_get_sn() has a similar problem.
Finally nfc_llcp_recv_snl() needs to make sure the socket
found by nfc_llcp_sock_from_sn() does not disappear.

Our current route lookups (mctp_route_lookup and mctp_route_lookup_null)
traverse the net's route list without the RCU read lock held. This means
the route lookup is subject to preemption, resulting in an potential
grace period expiry, and so an eventual kfree() while we still have the
route pointer.
Add the proper read-side critical section locks around the route
lookups, preventing premption and a possible parallel kfree.
The remaining net->mctp.routes accesses are already under a
rcu_read_lock, or protected by the RTNL for updates.
Based on an analysis from Sili Luo <rootlab@huawei.com>, where
introducing a delay in the route lookup could cause a UAF on
simultaneous sendmsg() and route deletion.

The problem is in ret_from_syscall where the check for
icache_44x_need_flush is done. When the flush is needed the code jumps
out-of-line to do the flush, and then intends to jump back to continue
the syscall return.
However the branch back to label 1b doesn't return to the correct
location, instead branching back just prior to the return to userspace,
causing bogus register values to be used by the rfi.
The breakage was introduced by commit 6f76a01173cc
("powerpc/syscall: implement system call entry/exit logic in C for PPC32") which
inadvertently removed the "1" label and reused it elsewhere.
Fix it by adding named local labels in the correct locations. Note that
the return label needs to be outside the ifdef so that CONFIG_PPC_47x=n
compiles.

When functions called by the trampoline panic, the backtrace that is
printed stops at the trampoline, because the trampoline does not store
its caller's frame address (backchain) on stack; it also stores the
return address at a wrong location.
Store both the same way as is already done for the regular eBPF programs.

One of the first things that s390x kernel functions do is storing the
the caller's frame address (backchain) on stack. This makes unwinding
possible. The backchain is always stored at frame offset 152, which is
inside the 160-byte stack area, that the functions allocate for their
callees. The callees must preserve the backchain; the remaining 152
bytes they may use as they please.
Currently the trampoline uses all 160 bytes, clobbering the backchain.
This causes kernel panics when using __builtin_return_address() in
functions called by the trampoline.
Fix by reducing the usage of the caller-reserved stack area by 8 bytes
in the trampoline.

Pull xen fix from Juergen Gross:
"A fix for the xen events driver:
Closing of an event channel in the Linux kernel can result in a
deadlock. This happens when the close is being performed in parallel
to an unrelated Xen console action and the handling of a Xen console
interrupt in an unprivileged guest.
The closing of an event channel is e.g. triggered by removal of a
paravirtual device on the other side. As this action will cause
console messages to be issued on the other side quite often, the
chance of triggering the deadlock is not negligible"

Static calls invocations aren't well supported from module __init and
__exit functions. Especially the static call from cleanup_trusted() led
to a crash on x86 kernel with CONFIG_DEBUG_VIRTUAL=y.
However, the usage of static call invocations for trusted_key_init()
and trusted_key_exit() don't add any value from either a performance or
security perspective. Hence switch to use indirect function calls instead.
Note here that although it will fix the current crash report, ultimately
the static call infrastructure should be fixed to either support its
future usage from module __init and __exit functions or not.

"A set of updates for interrupt chip drivers:
- Fix the fail of the Qualcomm PDC driver on v3.2 hardware which is
caused by a control bit being moved to a different location
- Update the SM8150 device tree PDC resource so the version register
can be read
- Make the Renesas RZG2L driver correct for interrupts which are
outside of the LSB in the TSSR register by using the proper macro
for calculating the mask
- Document the Renesas RZ2GL device tree binding correctly and update
them for a few devices which faul to boot otherwise
- Use the proper accessor in the RZ2GL driver instead of blindly
dereferencing an unchecked pointer
- Make GICv3 handle the dma-non-coherent attribute correctly
- Ensure that all interrupt controller nodes on RISCV are marked as
initialized correctly
Maintainer changes:
- Add a new entry for GIC interrupt controllers and assign Marc
Zyngier as the maintainer
- Remove Marc Zyngier from the core and driver maintainer entries as
he is burried in work and short of time to handle that.
Thanks to Marc for all the great work he has done in the past couple
of years!
Also note that commit 5873d380f4c0 ("irqchip/qcom-pdc: Add support for

The real author is Neil. His patch was posted by Dmitry once and Neil
picked it up from the list and reposted it with the bogus SOB chain.
Not a big deal, but worth to mention. I wanted to fix that up, but
then got distracted and Marc piled more changes on top. So I decided
to leave it as is instead of rebasing world"

Commit 546dea18c999 ("nvme-auth: check chap ctrl_key once constructed")
replaced the condition "if (ctrl->ctrl_key)" (indicating bidirectional
auth) by "if (chap->ctrl_key)", because ctrl->ctrl_key is a resource shared
with sysfs. But chap->ctrl_key is set in
nvme_auth_process_dhchap_challenge() depending on the DHVLEN in the
DH-HMAC-CHAP Challenge message received from the controller, and will thus
be non-NULL for every DH-HMAC-CHAP exchange, even if unidirectional auth
was requested. This will lead to a protocol violation by sending a Success2
message in the unidirectional case (per NVMe base spec 2.0, the
authentication transaction ends after the Success1 message for
unidirectional auth). Use chap->s2 instead, which is non-zero if and only
if the host requested bi-directional authentication from the controller.

From Alon:
"Due to a logical bug in the NVMe-oF/TCP subsystem in the Linux kernel,
a malicious user can cause a UAF and a double free, which may lead to
RCE (may also lead to an LPE in case the attacker already has local
privileges)."
Hence, when a queue initialization fails after the ahash requests are
allocated, it is guaranteed that the queue removal async work will be
called, hence leave the deallocation to the queue removal.
Also, be extra careful not to continue processing the socket, so set
queue rcv_state to NVMET_TCP_RECV_ERR upon a socket error.

This reverts commit 5f521494cc73520ffac18ede0758883b9aedd018.
The patch breaks mounts with security mount options like
$ mount -o context=system_u:object_r:root_t:s0 /dev/sdX /mn
mount: /mnt: wrong fs type, bad option, bad superblock on /dev/sdX, missing codepage or helper program, ...
We cannot reject all unknown options in btrfs_parse_subvol_options() as
intended, the security options can be present at this point and it's not
possible to enumerate them in a future proof way. This means unknown
mount options are silently accepted like before when the filesystem is
mounted with either -o subvol=/path or as followup mounts of the same
device.

Commit 1e66220948df8 ("net/mlx5e: Update rx ring hw mtu upon each rx-fcs

commit 0bc73ad46a76 ("net/mlx5e: Mutually exclude RX-FCS and

The impact of this is a little unclear since it seems the FCS scattered
with RX-FCS is (usually?) correct regardless.

The driver might pull connectors which weren't submitted by
user-space into the atomic state. For instance,
intel_dp_mst_atomic_master_trans_check() pulls in connectors
sharing the same DP-MST stream. However, if the connector is
unregistered, this later fails with:
[ 559.425658] i915 0000:00:02.0: [drm:drm_atomic_helper_check_modeset] [CONNECTOR:378:DP-7] is not registered
Skip the unregistered connector check to allow user-space to turn
off connectors one-by-one.

When the SMC protocol is built into the kernel proper while ISM is
configured to be built as module, linking the kernel fails due to
unresolved dependencies out of net/smc/smc_ism.o to
ism_get_smcd_ops, ism_register_client, and ism_unregister_client
as reported via the linux-next test automation (see link).
This however is a bug introduced a while ago.
Correct the dependency list in ISM's and SMC's Kconfig to reflect the
dependencies that are actually inverted. With this you cannot build a
kernel with CONFIG_SMC=y and CONFIG_ISM=m. Either ISM needs to be 'y',
too - or a 'n'. That way, SMC can still be configured on non-s390
architectures that do not have (nor need) an ISM driver.

The sta_himax83102 panel sometimes shows abnormally flickering
horizontal lines. The front gate output will precharge the X point of
the next pole circuit before TP(TouchPanel Enable) term starts, and wait
until the end of the TP term to resume the CLK. For this reason, the X
point must be maintained during the TP term. In abnormal case, we
measured a slight leakage at point X. This because during the TP term,
the GPW does not fully pull the VGL low, causing the TFT to not be
closed tightly.
To fix this, we completely pull GPW to VGL before entering the TP term.
This will ensure that the TFT is closed tightly and prevent the abnormal
display.

When updating the SA, use the new update_pn flags instead of comparing the
new PN with the initial one.
Comparing the initial PN value with the new value will allow the user
to update the SA using the initial PN value as a parameter like this:
$ ip macsec add macsec0 tx sa 0 pn 1 on key 00 \
ead3664f508eb06c40ac7104cdae4ce5
$ ip macsec set macsec0 tx sa 0 pn 1 off

When updating SA, update the PN only when the update_pn flag is true.
Otherwise, the PN will be reset to its previous value using the

Indicate next PN update using update_pn flag in macsec_context.
Offloaded MACsec implementations does not know whether or not the
MACSEC_SA_ATTR_PN attribute was passed for an SA update and assume
that next PN should always updated, but this is not always true.
The PN can be reset to its initial value using the following command:
$ ip macsec set macsec0 tx sa 0 off #octeontx2-pf case
Or, the update PN command will succeed even if the driver does not support
PN updates.
$ ip macsec set macsec0 tx sa 0 pn 1 on #mscc phy driver case
Comparing the initial PN with the new PN value is not a solution. When
the user updates the PN using its initial value the command will
succeed, even if the driver does not support it. Like this:
$ ip macsec add macsec0 tx sa 0 pn 1 on key 00 \
ead3664f508eb06c40ac7104cdae4ce5
$ ip macsec set macsec0 tx sa 0 pn 1 on #mlx5 case

Commit ff48b37802e5 ("scsi: Do not attempt to rescan suspended devices")
modified scsi_rescan_device() to avoid attempting rescanning a suspended
device. However, the modification added a check to verify that a SCSI
device is in the running state without checking if the device request
queue (in the case of block device) is also running, thus allowing the
exectuion of internal requests. Without checking the device request
queue, commit ff48b37802e5 fix is incomplete and deadlocks on resume can
still happen. Use blk_queue_pm_only() to check if the device request
queue allows executing commands in addition to checking the SCSI device
state.

fit3 protocol driver does not support accessing IDE control registers
(device control/altstatus). The DOS driver does not use these registers
either (as observed from DOSEMU trace). But the HW seems to be capable
of accessing these registers - I simply tried bit 3 and it works!
The control register is required to properly reset ATAPI devices or
they will be detected only once (after a power cycle).

Some parallel adapters (e.g. EXP Computer MC-1285B EPP Cable) return
bogus values when there's no master device present. This can cause
reset to fail, preventing the lone slave device (such as EXP Computer
CD-865) from working.
Add custom version of wait_after_reset that ignores master failure when
a slave device is present. The custom version is also needed because
the generic ata_sff_wait_after_reset uses direct port I/O for slave
device detection.

Ifcfg config file support in NetworkManger is deprecated. This patch
provides support for the new keyfile config format for connection
profiles in NetworkManager. The patch modifies the hv_kvp_daemon code
to generate the new network configuration in keyfile
format(.ini-style format) along with a ifcfg format configuration.
The ifcfg format configuration is also retained to support easy
backward compatibility for distro vendors. These configurations are
stored in temp files which are further translated using the
hv_set_ifconfig.sh script. This script is implemented by individual
distros based on the network management commands supported.
For example, RHEL's implementation could be found here:
https://gitlab.com/redhat/centos-stream/src/hyperv-daemons/-/blob/c9s/hv_set_ifconfig.sh
Debian's implementation could be found here:
https://github.com/endlessm/linux/blob/master/debian/cloud-tools/hv_set_ifconfig
The next part of this support is to let the Distro vendors consume
these modified implementations to the new configuration format.

The verifier, as part of check_return_code(), verifies that async
callbacks such as from e.g. timers, will return 0. It does this by
correctly checking that R0->var_off is in tnum_const(0), which
effectively checks that it's in a range of 0. If this condition fails,
however, it prints an error message which says that the value should
have been in (0x0; 0x1). This results in possibly confusing output such
as the following in which an async callback returns 1:
At async callback the register R0 has value (0x1; 0x0) should have been in (0x0; 0x1)
The fix is easy -- we should just pass the tnum_const(0) as the correct
range to verbose_invalid_scalar(), which will then print the following:
At async callback the register R0 has value (0x1; 0x0) should have been in (0x0; 0x0)

Surfaces can be backed (i.e. stored in) memory objects (mob's) which
are created and managed by the userspace as GEM buffers. Surfaces
grab only a ttm reference which means that the gem object can
be deleted underneath us, especially in cases where prime buffer
export is used.
Make sure that all userspace surfaces which are backed by gem objects
hold a gem reference to make sure they're not deleted before vmw
surfaces are done with them, which fixes:

The ASP1 DOUT line must be defaulted to be high-impedance when
it is not actually transmitting data for an active channel.
In non-SoundWire modes ASP1 will usually be shared by multiple
amps so each amp must only drive the line during the slot for
an enabled TX channel.
In SoundWire mode a custom firmware can use ASP1 as a secondary
chip-to-chip audio link or as GPIO. It should be defaulted to
high-impedance since by default the purpose of this pin is not
known.

One PID may appear multiple times in a preloaded pidlist.
(Possibly due to PID recycling but we have reports of the same
task_struct appearing with different PIDs, thus possibly involving
transfer of PID via de_thread().)
Because v1 seq_file iterator uses PIDs as position, it leads to
a message:
> seq_file: buggy .next function kernfs_seq_next did not update position index
Conservative and quick fix consists of removing duplicates from `tasks`
file (as opposed to removing pidlists altogether). It doesn't affect
correctness (it's sufficient to show a PID once), performance impact
would be hidden by unconditional sorting of the pidlist already in place
(asymptotically).
