commit a6555cb1cb69db479d0760e392c175ba32426842 upstream.
JieLi tends to use SCSI via USB Mass Storage to implement their own
proprietary commands instead of implementing another USB interface.
Enumerating it as a generic mass storage device will lead to a Hardware
Error sense key get reported.
Ignore this bogus device to prevent appearing a unusable sdX device
file.

commit d44238d8254a36249d576c96473269dbe500f5e4 upstream.
I have a ASUS PN51 S mini pc that has two xhci devices. One from AMD,
and other from ASMEDIA. The one from ASMEDIA have problems when resume
from suspend, and keep broken until unplug the power cord. I use this
kernel parameter: xhci-hcd.quirks=128 and then it works ok. I make a
path to reset only the ASMEDIA xhci.

commit 0d410e8913f5cffebcca79ffdd596009d4a13a28 upstream.
This commit addresses an issue where events were being processed when
the controller was in a halted state. To fix this issue by stop
processing the events as the event count was considered stale or
invalid when the controller was halted.

commit 71c717cd8a2e180126932cc6851ff21c1d04d69a upstream.
This reverts commit 86b20af11e84c26ae3fde4dcc4f490948e3f8035.
This patch leads to passing 0 to simple_read_from_buffer()
as a fifth argument, turning the read method into a nop.
The change is fundamentally flawed, as it breaks the driver.

commit 87b696209007b7c4ef7bdfe39ea0253404a43770 upstream.
Some Plantronics headset as the below send an unexcept opposite
volume key's HID report for each volume key press after 200ms, like
unecepted Volume Up Key following Volume Down key pressed by user.
This patch adds a quirk to hid-plantronics for these devices, which
will ignore the second unexcepted opposite volume key if it happens
within 220ms from the last one that was handled.
Plantronics EncorePro 500 Series (047f:431e)
Plantronics Blackwire_3325 Series (047f:430c)
The patch was tested on the mentioned model, it shouldn't affect
other models, however, this quirk might be needed for them too.
Auto-repeat (when a key is held pressed) is not affected per test
result.

commit c56f9ecb7fb6a3a90079c19eb4c8daf3bbf514b3 upstream.
Using the device-managed version allows to simplify clean-up in probe()
error path.
Additionally, this device-managed ensures proper cleanup, which helps to
resolve memory errors, page faults, btrfs going read-only, and btrfs
disk corruption.

[ Upstream commit 26dd6a5667f500c5d991f90a9ac5998a71afaf5c ]
There's a Cirque touchpad that wakes system up without anything touched
the touchpad. The input report is empty when this happens.
The reason is stated in HID over I2C spec, 7.2.8.2:
"If the DEVICE wishes to wake the HOST from its low power state, it can
issue a wake by asserting the interrupt."
This is fine if OS can put system back to suspend by identifying input
wakeup count stays the same on resume, like Chrome OS Dark Resume [0].
But for regular distro such policy is lacking.
Though the change doesn't bring any impact on power consumption for
touchpad is minimal, other i2c-hid device may depends on SLEEP control
power. So use a quirk to limit the change scope.

[ Upstream commit 740329d7120f8608ead64b0f3417c02ca1d6b32f ]
Added a gpiochip compatible driver to control the 8 GPIOs of
the MCP2200 by using the HID interface.
Using GPIOs with alternative functions (GP0<->SSPND, GP1<->USBCFG,
GP6<->RXLED, GP7<->TXLED) will reset the functions, if set (unset by
default).
The driver was tested while also using the UART of the chip. Setting
and reading the GPIOs has no effect on the UART communication. However,
a reset is triggered after the CONFIGURE command. If the GPIO Direction
is constantly changed, this will affect the communication at low baud
rates. This is a hardware problem of the MCP2200 and is not caused by
the driver.

[ Upstream commit f7345ccc62a4b880cf76458db5f320725f28e400 ]
After a CPU has set itself offline and before it eventually calls
rcutree_report_cpu_dead(), there are still opportunities for callbacks
to be enqueued, for example from a softirq. When that happens on NOCB,
the rcuog wake-up is deferred through an IPI to an online CPU in order
not to call into the scheduler and risk arming the RT-bandwidth after
hrtimers have been migrated out and disabled.
But performing a synchronized IPI from a softirq is buggy as reported in
the following scenario:
WARNING: CPU: 1 PID: 26 at kernel/smp.c:633 smp_call_function_single
Modules linked in: rcutorture torture

Fix this with forcing deferred rcuog wake up through the NOCB timer when
the CPU is offline. The actual wake up will happen from
rcutree_report_cpu_dead().

[ Upstream commit b913c3fe685e0aec80130975b0f330fd709ff324 ]
Currently IRQs are disabled on call_rcu() and then depending on the
context:
* If the CPU is in nocb mode:
- If the callback is enqueued in the bypass list, IRQs are re-enabled
implictly by rcu_nocb_try_bypass()
- If the callback is enqueued in the normal list, IRQs are re-enabled
implicitly by __call_rcu_nocb_wake()
* If the CPU is NOT in nocb mode, IRQs are reenabled explicitly from call_rcu()
This makes the code a bit hard to follow, especially as it interleaves
with nocb locking.
To make the IRQ flags coverage clearer and also in order to prepare for
moving all the nocb enqueue code to its own function, always re-enable
the IRQ flags explicitly from call_rcu().

[ Upstream commit 40dddd4b8bd08a69471efd96107a4e1c73fabefc ]
syzbot reported an issue in ppp_async_encode() [1]
In this case, pppoe_sendmsg() is called with a zero size.
Then ppp_async_encode() is called with an empty skb.

[ Upstream commit b5e837c86041bef60f36cf9f20a641a30764379a ]
Before commit addf9b90de22 ("net: rtnetlink: use rcu to free rtnl
message handlers"), once the first rtnl_register_module() allocated
rtnl_msg_handlers[PF_PHONET], the following calls never failed.
However, after the commit, rtnl_register_module() could fail silently
to allocate rtnl_msg_handlers[PF_PHONET][msgtype] and requires error
handling for each call.
Handling the error allows users to view a module as an all-or-nothing
thing in terms of the rtnetlink functionality. This prevents syzkaller
from reporting spurious errors from its tests, where OOM often occurs
and module is automatically loaded.
Let's use rtnl_register_many() to handle the errors easily.

route_dumpit() already relies on RCU, RTNL is not needed.
Also change return value at the end of a dump.
This allows NLMSG_DONE to be appended to the current

[ Upstream commit e39951d965bf58b5aba7f61dc1140dcb8271af22 ]
In commit af65bdfce98d ("[NETLINK]: Switch cb_lock spinlock
to mutex and allow to override it"), Patrick McHardy used
a common mutex to protect both nlk->cb and the dump() operations.
The override is used for rtnl dumps, registered with
rntl_register() and rntl_register_module().
We want to be able to opt-out some dump() operations
to not acquire RTNL, so we need to protect nlk->cb
with a per socket mutex.
This patch renames nlk->cb_def_mutex to nlk->nl_cb_mutex
The optional pointer to the mutex used to protect dump()
call is stored in nlk->dump_cb_mutex

However, after the commit, rtnl_msg_handler[protocol][msgtype] needs to
be allocated in each rtnl_register_module(), so each call could fail.
Many callers of rtnl_register_module() do not handle the returned error,
and we need to add many error handlings.
To handle that easily, let's add wrapper functions for bulk registration

[ Upstream commit ac888d58869bb99753e7652be19a151df9ecb35d ]
dst_entries_add() uses per-cpu data that might be freed at netns
dismantle from ip6_route_net_exit() calling dst_entries_destroy()
Before ip6_route_net_exit() can be called, we release all
the dsts associated with this netns, via calls to dst_release(),
which waits an rcu grace period before calling dst_destroy()
dst_entries_add() use in dst_destroy() is racy, because
dst_entries_destroy() could have been called already.
Decrementing the number of dsts must happen sooner.
Notes:
1) in CONFIG_XFRM case, dst_destroy() can call
dst_release_immediate(child), this might also cause UAF
if the child does not have DST_NOCOUNT set.
IPSEC maintainers might take a look and see how to address this.
2) There is also discussion about removing this count of dst,
which might happen in future kernels.

[ Upstream commit 0bfcb7b71e735560077a42847f69597ec7dcc326 ]
syzbot managed to call xt_cluster match via ebtables:
WARNING: CPU: 0 PID: 11 at net/netfilter/xt_cluster.c:72 xt_cluster_mt+0x196/0x780
[..]
ebt_do_table+0x174b/0x2a40
Module registers to NFPROTO_UNSPEC, but it assumes ipv4/ipv6 packet
processing. As this is only useful to restrict locally terminating
TCP/UDP traffic, register this for ipv4 and ipv6 family only.
Pablo points out that this is a general issue, direct users of the
set/getsockopt interface can call into targets/matches that were only
intended for use with ip(6)tables.
Check all UNSPEC matches and targets for similar issues:
- matches and targets are fine except if they assume skb_network_header()
is valid -- this is only true when called from inet layer: ip(6) stack
pulls the ip/ipv6 header into linear data area.
- targets that return XT_CONTINUE or other xtables verdicts must be
restricted too, they are incompatbile with the ebtables traverser, e.g.
EBT_CONTINUE is a completely different value than XT_CONTINUE.
Most matches/targets are changed to register for NFPROTO_IPV4/IPV6, as
they are provided for use by ip(6)tables.
The MARK target is also used by arptables, so register for NFPROTO_ARP too.
While at it, bail out if connbytes fails to enable the corresponding
conntrack family.
This change passes the selftests in iptables.git.

[ Upstream commit 4d5c70e6155d5eae198bade4afeab3c1b15073b6 ]
If hashing fails in sctp_listen_start(), the socket remains in the
LISTENING state, even though it was not added to the hash table.
This can lead to a scenario where a socket appears to be listening
without actually being accessible.
This patch ensures that if the hashing operation fails, the sk_state
is set back to CLOSED before returning an error.
Note that there is no need to undo the autobind operation if hashing
fails, as the bind port can still be used for next listen() call on
the same socket.

At btrfs_load_zone_info() we have an error path that is dereferencing

The problem is there since commit 08e11a3db098 ("btrfs: zoned: load zone's

then later on that code was factored out into the helper

Most qdiscs maintain their backlog using qdisc_pkt_len(skb)
on the assumption it is invariant between the enqueue()
and dequeue() handlers.
Unfortunately syzbot can crash a host rather easily using
a TBF + SFQ combination, with an STAB on SFQ [1]
We can't support TCA_STAB on arbitrary level, this would
require to maintain per-qdisc storage.

[ Upstream commit 9d9e5347b035412daa844f884b94a05bac94f864 ]
Sporadic issues, such as PHY access loss, have been observed on I219 (19)
devices. It was found that these devices have hardware more closely
related to ADP than MTP and the issues were caused by taking MTP-specific
flows.
Change the MAC and board types of these devices from MTP to ADP to
correctly reflect the LAN hardware, and flows, of these devices.

Commit 004d25060c78 ("igb: Fix igb_down hung on surprise removal")
changed igb_io_error_detected() to ignore non-fatal pcie errors in order
to avoid hung task that can happen when igb_down() is called multiple
times. This caused an issue when processing transient non-fatal errors.
igb_io_resume(), which is called after igb_io_error_detected(), assumes
that device is brought down by igb_io_error_detected() if the interface
is up. This resulted in panic with stacktrace below.

[ Upstream commit dac6c7b3d33756d6ce09f00a96ea2ecd79fae9fb ]
This patch addresses a macvlan leak issue in the i40e driver caused by
concurrent access to vsi->mac_filter_hash. The leak occurs when multiple
threads attempt to modify the mac_filter_hash simultaneously, leading to
inconsistent state and potential memory leaks.
To fix this, we now wrap the calls to i40e_del_mac_filter() and zeroing
vf->default_lan_addr.addr with spin_lock/unlock_bh(&vsi->mac_filter_hash_lock),
ensuring atomic operations and preventing concurrent access.
Additionally, we add lockdep_assert_held(&vsi->mac_filter_hash_lock) in
i40e_add_mac_filter() to help catch similar issues in the future.
Reproduction steps:
1. Spawn VFs and configure port vlan on them.
2. Trigger concurrent macvlan operations (e.g., adding and deleting
portvlan and/or mac filters).
3. Observe the potential memory leak and inconsistent state in the
mac_filter_hash.
This synchronization ensures the integrity of the mac_filter_hash and prevents
the described leak.

[ Upstream commit fbcb968a98ac0b71f5a2bda2751d7a32d201f90d ]
Triggering the reset while in switchdev mode causes
errors[1]. Rules are already removed by this time
because switch content is flushed in case of the reset.
This means that rules were deleted from HW but SW
still thinks they exist so when we get
SWITCHDEV_FDB_DEL_TO_DEVICE notification we try to
delete not existing rule.
We can avoid these errors by clearing the rules
early in the reset flow before they are removed from HW.
Switchdev API will get notified that the rule was removed
so we won't get SWITCHDEV_FDB_DEL_TO_DEVICE notification.
Remove unnecessary ice_clear_sw_switch_recipes.

Eswitch is used as a prefix for related functions. Main structure
storing all data related to eswitch should also be named as eswitch
instead of ice_switchdev_info. Rename it.
Also rename switchdev to eswitch where the context is not about eswitch
mode.
::uplink_netdev was changed to netdev for simplicity. There is no other

netif_is_ice() works by checking the pointer to netdev ops. However, it
only checks for the default ice_netdev_ops, not ice_netdev_safe_mode_ops,
so in Safe Mode it always returns false, which is unintuitive. While it
doesn't look like netif_is_ice() is currently being called anywhere in Safe
Mode, this could change and potentially lead to unexpected behaviour.

[ Upstream commit 1d390923974cc233245649cf23833e06b15a9ef7 ]
The hardware definition of every TPMI feature contains a major and minor
version. When there is a change in the MMIO offset or change in the
definition of a field, hardware will change major version. For addition
of new fields without modifying existing MMIO offsets or fields, only
the minor version is changed.
If the driver has not been updated to recognize a new hardware major
version, it cannot provide the RAPL interface to users due to possible
register layout incompatibilities. However, the driver does not need to
be updated every time the hardware minor version changes because in that
case it will just miss some new functionality exposed by the hardware.
The current implementation causes the driver to refuse to work for any
hardware version change which is unnecessarily restrictive.
If there is a minor version mismatch, log an information message and
continue, but if there is a major version mismatch, log a warning and
exit (as before).
