+Subject: block: fix kobject leak in blk_unregister_queue
+
+From: Ming Lei <ming.lei@redhat.com>
+
+[ Upstream commit 3051247e4faa32a3d90c762a243c2c62dde310db ]
+
+The kobject for the queue, `disk->queue_kobj`, is initialized with a
+reference count of 1 via `kobject_init()` in `blk_register_queue()`.
+While `kobject_del()` is called during the unregister path to remove
+the kobject from sysfs, the initial reference is never released.
+
+Add a call to `kobject_put()` in `blk_unregister_queue()` to properly
+decrement the reference count and fix the leak.

+Subject: Bluetooth: Fix null-ptr-deref in l2cap_sock_resume_cb()
+
+From: Kuniyuki Iwashima <kuniyu@google.com>
+
+[ Upstream commit a0075accbf0d76c2dad1ad3993d2e944505d99a0 ]
+
+syzbot reported null-ptr-deref in l2cap_sock_resume_cb(). [0]
+
+l2cap_sock_resume_cb() has a similar problem that was fixed by commit
+1bff51ea59a9 ("Bluetooth: fix use-after-free error in lock_sock_nested()").
+
+Since both l2cap_sock_kill() and l2cap_sock_resume_cb() are executed
+under l2cap_sock_resume_cb(), we can avoid the issue simply by checking
+if chan->data is NULL.
+
+Let's not access to the killed socket in l2cap_sock_resume_cb().

+Subject: Bluetooth: hci_sync: fix connectable extended advertising when using
+ static random address
+
+From: Alessandro Gasbarroni <alex.gasbarroni@gmail.com>
+
+[ Upstream commit d85edab911a4c1fcbe3f08336eff5c7feec567d0 ]
+
+Currently, the connectable flag used by the setup of an extended
+advertising instance drives whether we require privacy when trying to pass
+a random address to the advertising parameters (Own Address).
+If privacy is not required, then it automatically falls back to using the
+controller's public address. This can cause problems when using controllers
+that do not have a public address set, but instead use a static random
+address.
+
+e.g. Assume a BLE controller that does not have a public address set.
+The controller upon powering is set with a random static address by default
+by the kernel.
+
+       < HCI Command: LE Set Random Address (0x08|0x0005) plen 6
+               Address: E4:AF:26:D8:3E:3A (Static)
+       > HCI Event: Command Complete (0x0e) plen 4
+             LE Set Random Address (0x08|0x0005) ncmd 1
+               Status: Success (0x00)
+
+Setting non-connectable extended advertisement parameters in bluetoothctl
+mgmt
+
+       add-ext-adv-params -r 0x801 -x 0x802 -P 2M -g 1
+
+correctly sets Own address type as Random
+
+       < HCI Command: LE Set Extended Advertising Parameters (0x08|0x0036)
+       plen 25
+               ...
+           Own address type: Random (0x01)
+
+Setting connectable extended advertisement parameters in bluetoothctl mgmt
+
+       add-ext-adv-params -r 0x801 -x 0x802 -P 2M -g -c 1
+
+mistakenly sets Own address type to Public (which causes to use Public
+Address 00:00:00:00:00:00)
+
+       < HCI Command: LE Set Extended Advertising Parameters (0x08|0x0036)
+       plen 25
+               ...
+           Own address type: Public (0x00)
+
+This causes either the controller to emit an Invalid Parameters error or to
+mishandle the advertising.
+
+This patch makes sure that we use the already set static random address
+when requesting a connectable extended advertising when we don't require
+privacy and our public address is not set (00:00:00:00:00:00).

+
+From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
+
+[ Upstream commit 6ef99c917688a8510259e565bd1b168b7146295a ]
+
+This replaces the usage of HCI_ERROR_REMOTE_USER_TERM, which as the name
+suggest is to indicate a regular disconnection initiated by an user,
+with HCI_ERROR_AUTH_FAILURE to indicate the session has timeout thus any
+pairing shall be considered as failed.

+
+[ Upstream commit f8242745871f81a3ac37f9f51853d12854fd0b58 ]
+
+static const char fmt[] = "%p%";
+    bpf_trace_printk(fmt, sizeof(fmt));
+
+The above BPF program isn't rejected and causes a kernel warning at

+    WARNING: CPU: 1 PID: 7244 at lib/vsprintf.c:2680 format_decode+0x49c/0x5d0
+
+This happens because bpf_bprintf_prepare skips over the second %,
+detected as punctuation, while processing %p. This patch fixes it by
+not skipping over punctuation. %\x00 is then processed in the next
+iteration and rejected.

+Subject: cachefiles: Fix the incorrect return value in __cachefiles_write()
+
+From: Zizhi Wo <wozizhi@huawei.com>
+
+[ Upstream commit 6b89819b06d8d339da414f06ef3242f79508be5e ]
+
+In __cachefiles_write(), if the return value of the write operation > 0, it
+is set to 0. This makes it impossible to distinguish scenarios where a
+partial write has occurred, and will affect the outer calling functions:
+
+ 1) cachefiles_write_complete() will call "term_func" such as
+netfs_write_subrequest_terminated(). When "ret" in __cachefiles_write()
+is used as the "transferred_or_error" of this function, it can not
+distinguish the amount of data written, makes the WARN meaningless.
+
+ 2) cachefiles_ondemand_fd_write_iter() can only assume all writes were
+successful by default when "ret" is 0, and unconditionally return the full
+length specified by user space.
+
+Fix it by modifying "ret" to reflect the actual number of bytes written.
+Furthermore, returning a value greater than 0 from __cachefiles_write()
+does not affect other call paths, such as cachefiles_issue_write() and
+fscache_write().

+Subject: can: tcan4x5x: fix reset gpio usage during probe
+
+From: Brett Werling <brett.werling@garmin.com>
+
+[ Upstream commit 0f97a7588db7a545ea07ee0d512789bfad4931d8 ]
+
+Fixes reset GPIO usage during probe by ensuring we retrieve the GPIO and
+take the device out of reset (if it defaults to being in reset) before
+we attempt to communicate with the device. This is achieved by moving
+the call to tcan4x5x_get_gpios() before tcan4x5x_find_version() and
+avoiding any device communication while getting the GPIOs. Once we
+determine the version, we can then take the knowledge of which GPIOs we
+obtained and use it to decide whether we need to disable the wake or
+state pin functions within the device.
+
+This change is necessary in a situation where the reset GPIO is pulled
+high externally before the CPU takes control of it, meaning we need to
+explicitly bring the device out of reset before we can start
+communicating with it at all.
+
+This also has the effect of fixing an issue where a reset of the device
+would occur after having called tcan4x5x_disable_wake(), making the
+original behavior not actually disable the wake. This patch should now
+disable wake or state pin functions well after the reset occurs.

+Subject: drm/mediatek: Add wait_event_timeout when disabling plane
+
+From: Jason-JH Lin <jason-jh.lin@mediatek.com>
+
+[ Upstream commit d208261e9f7c66960587b10473081dc1cecbe50b ]
+
+Our hardware registers are set through GCE, not by the CPU.
+DRM might assume the hardware is disabled immediately after calling
+atomic_disable() of drm_plane, but it is only truly disabled after the
+GCE IRQ is triggered.
+
+Additionally, the cursor plane in DRM uses async_commit, so DRM will
+not wait for vblank and will free the buffer immediately after calling
+atomic_disable().
+
+To prevent the framebuffer from being freed before the layer disable
+settings are configured into the hardware, which can cause an IOMMU
+fault error, a wait_event_timeout has been added to wait for the
+ddp_cmdq_cb() callback,indicating that the GCE IRQ has been triggered.

+
+[ Upstream commit e5478166dffb51fa64e76cdbb5c24421f22f2d43 ]
+
+nouveau_drm_ioctl() only checks the _IOC_NR() bits in the
+DRM_NOUVEAU_NVIF command, but ignores the type and direction bits, so any
+command with '7' in the low eight bits gets passed into
+nouveau_abi16_ioctl() instead of drm_ioctl().
+
+Check for all the bits except the size that is handled inside of the
+handler.

+[ Upstream commit a4d1c5d0b99b75263a5626d2e52d569db3844b33 ]
+
+Since the GuC is reset during GT reset, we need to re-send the
+entire SR-IOV provisioning configuration to the GuC. But since
+this whole configuration is protected by the PF master mutex and
+we can't avoid making allocations under this mutex (like during
+LMEM provisioning), we can't do this reprovisioning from gt-reset
+path if we want to be reclaim-safe. Move VFs reprovisioning to a
+async worker that we will start from the gt-reset path.

+
+As part of the resume or GT reset, the PF driver schedules work
+which is then used to complete restarting of the SR-IOV support,
+including resending to the GuC configurations of provisioned VFs.
+
+However, in case of short delay between those two actions, which
+could be seen by triggering a GT reset on the suspened device:
+
+ $ echo 1 > /sys/kernel/debug/dri/0000:00:02.0/gt0/force_reset
+
+this PF worker might be still busy, which lead to errors due to
+just stopped or disabled GuC CTB communication:

+MIME-Version: 1.0

+[ Upstream commit 13a48a0fa52352f9fe58e2e1927670dcfea64c3a ]
+
+Some VF accessible registers (like GuC scratch registers) must be
+explicitly reset during the FLR. While this is today done by the GuC
+firmware, according to the design, this should be responsibility of
+the PF driver, as future platforms may require more registers to be
+reset. Likewise GuC, the PF can access VFs registers by adding some
+platform specific offset to the original register address.

+ paths
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+
+[ Upstream commit 64e135f1eaba0bbb0cdee859af3328c68d5b9789 ]
+
+When processing mount options, efivarfs allocates efivarfs_fs_info (sfi)
+early in fs_context initialization. However, sfi is associated with the
+superblock and typically freed when the superblock is destroyed. If the
+fs_context is released (final put) before fill_super is called—such as
+on error paths or during reconfiguration—the sfi structure would leak,
+as ownership never transfers to the superblock.
+
+Implement the .free callback in efivarfs_context_ops to ensure any
+allocated sfi is properly freed if the fs_context is torn down before
+fill_super, preventing this memory leak.

+From: Dave Ertman <david.m.ertman@intel.com>
+
+[ Upstream commit 3ce58b01ada408b372f15b7c992ed0519840e3cf ]
+
+The function ice_lag_is_switchdev_running() is being called from outside of
+the LAG event handler code.  This results in the lag->upper_netdev being
+NULL sometimes.  To avoid a NULL-pointer dereference, there needs to be a
+check before it is dereferenced.

+Subject: libbpf: Fix handling of BPF arena relocations
+
+From: Andrii Nakryiko <andrii@kernel.org>
+
+[ Upstream commit 0238c45fbbf8228f52aa4642f0cdc21c570d1dfe ]
+
+Initial __arena global variable support implementation in libbpf
+contains a bug: it remembers struct bpf_map pointer for arena, which is
+used later on to process relocations. Recording this pointer is
+problematic because map pointers are not stable during ELF relocation
+collection phase, as an array of struct bpf_map's can be reallocated,
+invalidating all the pointers. Libbpf is dealing with similar issues by
+using a stable internal map index, though for BPF arena map specifically
+this approach wasn't used due to an oversight.
+
+The resulting behavior is non-deterministic issue which depends on exact
+layout of ELF object file, number of actual maps, etc. We didn't hit
+this until very recently, when this bug started triggering crash in BPF
+CI when validating one of sched-ext BPF programs.
+
+The fix is rather straightforward: we just follow an established pattern
+of remembering map index (just like obj->kconfig_map_idx, for example)
+instead of `struct bpf_map *`, and resolving index to a pointer at the
+point where map information is necessary.
+
+While at it also add debug-level message for arena-related relocation
+resolution information, which we already have for all other kinds of
+maps.

+
+The lockdep tool can report a circular lock dependency warning in the loop
+driver's AIO read/write path:
+
+```
+[ 6540.587728] kworker/u96:5/72779 is trying to acquire lock:

+[ 6540.620210]
+[ 6540.620210] other info that might help us debug this:
+[ 6540.627499]  Possible unsafe locking scenario:
+[ 6540.627499]

+[ 6540.646988]
+[ 6540.646988]  *** DEADLOCK ***
+```
+
+This patch fixes the issue by using the AIO-specific helpers
+`kiocb_start_write()` and `kiocb_end_write()`. These functions are
+designed to be used with a `kiocb` and manage write sequencing
+correctly for asynchronous I/O without introducing the problematic
+lock dependency.
+
+The `kiocb` is already part of the `loop_cmd` struct, so this change
+also simplifies the completion function `lo_rw_aio_do_completion()` by
+using the `iocb` from the `cmd` struct directly, instead of retrieving
+the loop device from the request queue.

+
+[ Upstream commit 683dc24da8bf199bb7446e445ad7f801c79a550e ]
+
+Do not offload IGMP/MLD messages as it could lead to IGMP/MLD Reports
+being unintentionally flooded to Hosts. Instead, let the bridge decide
+where to send these IGMP/MLD messages.

+Consider the case where the local host is sending out reports in response

+
+       mcast-listener-process (IP_ADD_MEMBERSHIP)

+         /   \
+      swp1   swp2
+        |     |
+  QUERIER     SOME-OTHER-HOST

+Since "net: gro: use cb instead of skb->network_header", the skb network

+Subject: net/mlx5: Correctly set gso_size when LRO is used
+
+From: Christoph Paasch <cpaasch@openai.com>
+
+[ Upstream commit 531d0d32de3e1b6b77a87bd37de0c2c6e17b496a ]
+
+gso_size is expected by the networking stack to be the size of the
+payload (thus, not including ethernet/IP/TCP-headers). However, cqe_bcnt
+is the full sized frame (including the headers). Dividing cqe_bcnt by
+lro_num_seg will then give incorrect results.
+
+For example, running a bpftrace higher up in the TCP-stack
+(tcp_event_data_recv), we commonly have gso_size set to 1450 or 1451 even
+though in reality the payload was only 1448 bytes.
+
+This can have unintended consequences:
+- In tcp_measure_rcv_mss() len will be for example 1450, but. rcv_mss
+will be 1448 (because tp->advmss is 1448). Thus, we will always
+recompute scaling_ratio each time an LRO-packet is received.
+- In tcp_gro_receive(), it will interfere with the decision whether or
+not to flush and thus potentially result in less gro'ed packets.
+
+So, we need to discount the protocol headers from cqe_bcnt so we can
+actually divide the payload by lro_num_seg to get the real gso_size.

+Subject: net: phy: Don't register LEDs for genphy
+
+From: Sean Anderson <sean.anderson@linux.dev>
+
+[ Upstream commit f0f2b992d8185a0366be951685e08643aae17d6d ]
+
+If a PHY has no driver, the genphy driver is probed/removed directly in
+phy_attach/detach. If the PHY's ofnode has an "leds" subnode, then the
+LEDs will be (un)registered when probing/removing the genphy driver.
+This could occur if the leds are for a non-generic driver that isn't
+loaded for whatever reason. Synchronously removing the PHY device in
+phy_detach leads to the following deadlock:
+
+rtnl_lock()
+ndo_close()
+    ...
+    phy_detach()
+        phy_remove()
+            phy_leds_unregister()
+                led_classdev_unregister()
+                    led_trigger_set()
+                        netdev_trigger_deactivate()
+                            unregister_netdevice_notifier()
+                                rtnl_lock()
+
+There is a corresponding deadlock on the open/register side of things
+(and that one is reported by lockdep), but it requires a race while this
+one is deterministic.
+
+Generic PHYs do not support LEDs anyway, so don't bother registering
+them.

+Subject: net/sched: Return NULL when htb_lookup_leaf encounters an empty
+ rbtree
+
+From: William Liu <will@willsroot.io>
+
+[ Upstream commit 0e1d5d9b5c5966e2e42e298670808590db5ed628 ]
+
+htb_lookup_leaf has a BUG_ON that can trigger with the following:
+
+tc qdisc del dev lo root
+tc qdisc add dev lo root handle 1: htb default 1
+tc class add dev lo parent 1: classid 1:1 htb rate 64bit
+tc qdisc add dev lo parent 1:1 handle 2: netem
+tc qdisc add dev lo parent 2:1 handle 3: blackhole
+ping -I lo -c1 -W0.001 127.0.0.1
+
+The root cause is the following:
+
+1. htb_dequeue calls htb_dequeue_tree which calls the dequeue handler on
+   the selected leaf qdisc
+2. netem_dequeue calls enqueue on the child qdisc
+3. blackhole_enqueue drops the packet and returns a value that is not
+   just NET_XMIT_SUCCESS
+4. Because of this, netem_dequeue calls qdisc_tree_reduce_backlog, and
+   since qlen is now 0, it calls htb_qlen_notify -> htb_deactivate ->
+   htb_deactiviate_prios -> htb_remove_class_from_row -> htb_safe_rb_erase
+5. As this is the only class in the selected hprio rbtree,
+   __rb_change_child in __rb_erase_augmented sets the rb_root pointer to
+   NULL
+6. Because blackhole_dequeue returns NULL, netem_dequeue returns NULL,
+   which causes htb_dequeue_tree to call htb_lookup_leaf with the same
+   hprio rbtree, and fail the BUG_ON
+
+The function graph for this scenario is shown here:
+ 0)               |  htb_enqueue() {
+ 0) + 13.635 us   |    netem_enqueue();
+ 0)   4.719 us    |    htb_activate_prios();
+ 0) # 2249.199 us |  }
+ 0)               |  htb_dequeue() {
+ 0)   2.355 us    |    htb_lookup_leaf();
+ 0)               |    netem_dequeue() {
+ 0) + 11.061 us   |      blackhole_enqueue();
+ 0)               |      qdisc_tree_reduce_backlog() {

+ 0)   1.873 us    |          qdisc_match_from_root();
+ 0)   6.292 us    |        }
+ 0)   1.894 us    |        htb_search();

+ 0)               |    htb_lookup_leaf() {
+ 0)               |      BUG_ON();
+ ------------------------------------------
+
+The full original bug report can be seen here [1].
+
+We can fix this just by returning NULL instead of the BUG_ON,
+as htb_dequeue_tree returns NULL when htb_lookup_leaf returns

+Subject: net/sched: sch_qfq: Fix race condition on qfq_aggregate
+
+From: Xiang Mei <xmei5@asu.edu>
+
+[ Upstream commit 5e28d5a3f774f118896aec17a3a20a9c5c9dfc64 ]
+
+A race condition can occur when 'agg' is modified in qfq_change_agg
+(called during qfq_enqueue) while other threads access it
+concurrently. For example, qfq_dump_class may trigger a NULL
+dereference, and qfq_delete_class may cause a use-after-free.
+
+This patch addresses the issue by:
+
+1. Moved qfq_destroy_class into the critical section.
+
+2. Added sch_tree_lock protection to qfq_dump_class and
+qfq_dump_class_stats.

+Subject: net: vlan: fix VLAN 0 refcount imbalance of toggling filtering during
+ runtime
+
+From: Dong Chenchen <dongchenchen2@huawei.com>
+
+[ Upstream commit 579d4f9ca9a9a605184a9b162355f6ba131f678d ]
+
+Assuming the "rx-vlan-filter" feature is enabled on a net device, the
+8021q module will automatically add or remove VLAN 0 when the net device
+is put administratively up or down, respectively. There are a couple of
+problems with the above scheme.
+
+The first problem is a memory leak that can happen if the "rx-vlan-filter"
+feature is disabled while the device is running:
+
+ # ip link add bond1 up type bond mode 0
+ # ethtool -K bond1 rx-vlan-filter off
+ # ip link del dev bond1
+
+When the device is put administratively down the "rx-vlan-filter"
+feature is disabled, so the 8021q module will not remove VLAN 0 and the
+memory will be leaked [1].
+
+Another problem that can happen is that the kernel can automatically
+delete VLAN 0 when the device is put administratively down despite not
+adding it when the device was put administratively up since during that
+time the "rx-vlan-filter" feature was disabled. null-ptr-unref or
+bug_on[2] will be triggered by unregister_vlan_dev() for refcount
+imbalance if toggling filtering during runtime:
+
+$ ip link add bond0 type bond mode 0
+$ ip link add link bond0 name vlan0 type vlan id 0 protocol 802.1q
+$ ethtool -K bond0 rx-vlan-filter off
+$ ifconfig bond0 up
+$ ethtool -K bond0 rx-vlan-filter on
+$ ifconfig bond0 down
+$ ip link del vlan0
+
+Root cause is as below:
+step1: add vlan0 for real_dev, such as bond, team.
+register_vlan_dev
+    vlan_vid_add(real_dev,htons(ETH_P_8021Q),0) //refcnt=1
+step2: disable vlan filter feature and enable real_dev
+step3: change filter from 0 to 1
+vlan_device_event
+    vlan_filter_push_vids
+        ndo_vlan_rx_add_vid //No refcnt added to real_dev vlan0
+step4: real_dev down
+vlan_device_event
+    vlan_vid_del(dev, htons(ETH_P_8021Q), 0); //refcnt=0
+        vlan_info_rcu_free //free vlan0
+step5: delete vlan0
+unregister_vlan_dev
+    BUG_ON(!vlan_info); //vlan_info is null
+
+Fix both problems by noting in the VLAN info whether VLAN 0 was
+automatically added upon NETDEV_UP and based on that decide whether it
+should be deleted upon NETDEV_DOWN, regardless of the state of the
+"rx-vlan-filter" feature.

+a partially initialised state:
+
+ ct hlist pointer is garbage; looks like the ct hash value
+ (hence crash).
+ ct->status is equal to IPS_CONFIRMED|IPS_DYING, which is expected
+ ct->timeout is 30000 (=30s), which is unexpected.
+
+Everything else looks like normal udp conntrack entry.  If we ignore
+ct->status and pretend its 0, the entry matches those that are newly
+allocated but not yet inserted into the hash:
+  - ct hlist pointers are overloaded and store/cache the raw tuple hash
+  - ct->timeout matches the relative time expected for a new udp flow
+    rather than the absolute 'jiffies' value.
+
+If it were not for the presence of IPS_CONFIRMED,
+__nf_conntrack_find_get() would have skipped the entry.
+
+Theory is that we did hit following race:
+
+cpu x                  cpu y                   cpu z
+ found entry E         found entry E
+ E is expired          <preemption>
+ nf_ct_delete()
+ return E to rcu slab
+                                       init_conntrack
+                                       E is re-inited,
+                                       ct->status set to 0
+                                       reply tuplehash hnnode.pprev
+                                       stores hash value.
+
+cpu y found E right before it was deleted on cpu x.
+E is now re-inited on cpu z.  cpu y was preempted before
+checking for expiry and/or confirm bit.
+
+                                       ->refcnt set to 1
+                                       E now owned by skb
+                                       ->timeout set to 30000
+
+If cpu y were to resume now, it would observe E as
+expired but would skip E due to missing CONFIRMED bit.
+
+                                       nf_conntrack_confirm gets called
+                                       sets: ct->status |= CONFIRMED
+                                       This is wrong: E is not yet added
+                                       to hashtable.
+
+cpu y resumes, it observes E as expired but CONFIRMED:
+                       <resumes>
+                       nf_ct_expired()
+                        -> yes (ct->timeout is 30s)
+                       confirmed bit set.
+
+cpu y will try to delete E from the hashtable:
+                       nf_ct_delete() -> set DYING bit
+                       __nf_ct_delete_from_lists
+
+Even this scenario doesn't guarantee a crash:
+cpu z still holds the table bucket lock(s) so y blocks:
+
+                       wait for spinlock held by z
+
+                                       CONFIRMED is set but there is no
+                                       guarantee ct will be added to hash:
+                                       "chaintoolong" or "clash resolution"
+                                       logic both skip the insert step.
+                                       reply hnnode.pprev still stores the
+                                       hash value.
+
+                                       unlocks spinlock
+                                       return NF_DROP
+                       <unblocks, then
+                        crashes on hlist_nulls_del_rcu pprev>
+
+In case CPU z does insert the entry into the hashtable, cpu y will unlink
+E again right away but no crash occurs.
+
+Without 'cpu y' race, 'garbage' hlist is of no consequence:
+ct refcnt remains at 1, eventually skb will be free'd and E gets
+destroyed via: nf_conntrack_put -> nf_conntrack_destroy -> nf_ct_destroy.
+
+To resolve this, move the IPS_CONFIRMED assignment after the table
+insertion but before the unlock.
+
+Pablo points out that the confirm-bit-store could be reordered to happen
+before hlist add resp. the timeout fixup, so switch to set_bit and
+before_atomic memory barrier to prevent this.
+
+It doesn't matter if other CPUs can observe a newly inserted entry right
+before the CONFIRMED bit was set:
+
+Such event cannot be distinguished from above "E is the old incarnation"
+case: the entry will be skipped.
+
+Also change nf_ct_should_gc() to first check the confirmed bit.
+
+The gc sequence is:
+ 1. Check if entry has expired, if not skip to next entry
+ 2. Obtain a reference to the expired entry.
+ 3. Call nf_ct_should_gc() to double-check step 1.
+
+nf_ct_should_gc() is thus called only for entries that already failed an
+expiry check. After this patch, once the confirmed bit check passes
+ct->timeout has been altered to reflect the absolute 'best before' date
+instead of a relative time.  Step 3 will therefore not remove the entry.
+
+Without this change to nf_ct_should_gc() we could still get this sequence:
+
+ 1. Check if entry has expired.
+ 2. Obtain a reference.
+ 3. Call nf_ct_should_gc() to double-check step 1:
+    4 - entry is still observed as expired
+    5 - meanwhile, ct->timeout is corrected to absolute value on other CPU
+      and confirm bit gets set
+    6 - confirm bit is seen
+    7 - valid entry is removed again
+
+First do check 6), then 4) so the gc expiry check always picks up either
+confirmed bit unset (entry gets skipped) or expiry re-check failure for
+re-inited conntrack objects.
+
+This change cannot be backported to releases before 5.19. Without
+commit 8a75a2c17410 ("netfilter: conntrack: remove unconfirmed list")
+|= IPS_CONFIRMED line cannot be moved without further changes.

+From: Zheng Qixing <zhengqixing@huawei.com>
+
+[ Upstream commit 80d7762e0a42307ee31b21f090e21349b98c14f6 ]
+
+When inserting a namespace into the controller's namespace list, the
+function uses list_add_rcu() when the namespace is inserted in the middle
+of the list, but falls back to a regular list_add() when adding at the
+head of the list.
+
+This inconsistency could lead to race conditions during concurrent
+access, as users might observe a partially updated list. Fix this by
+consistently using list_add_rcu() in both code paths to ensure proper
+RCU protection throughout the entire function.

+
+[ Upstream commit 71257925e83eae1cb6913d65ca71927d2220e6d1 ]
+
+Procedures for nvme-mpath IO accounting:
+
+ 1) initialize nvme_request and clear flags;
+ 2) set NVME_MPATH_IO_STATS and increase inflight counter when IO
+    started;
+ 3) check NVME_MPATH_IO_STATS and decrease inflight counter when IO is
+    done;
+
+However, for the case nvme_fail_nonready_command(), both step 1) and 2)
+are skipped, and if old nvme_request set NVME_MPATH_IO_STATS and then
+request is reused, step 3) will still be executed, causing inflight I/O
+counter to be negative.
+
+Fix the problem by clearing nvme_request in nvme_fail_nonready_command().

+need to acquire a write lock on sk_callback_lock.  Previously, a read
+lock was used, which is insufficient for modifying sk_user_data and
+sk_data_ready.

+Subject: Revert "cgroup_freezer: cgroup_freezing: Check if not frozen"
+
+From: Chen Ridong <chenridong@huawei.com>
+
+[ Upstream commit 14a67b42cb6f3ab66f41603c062c5056d32ea7dd ]
+
+This reverts commit cff5f49d433fcd0063c8be7dd08fa5bf190c6c37.
+
+Commit cff5f49d433f ("cgroup_freezer: cgroup_freezing: Check if not
+frozen") modified the cgroup_freezing() logic to verify that the FROZEN
+flag is not set, affecting the return value of the freezing() function,
+in order to address a warning in __thaw_task.
+
+A race condition exists that may allow tasks to escape being frozen. The
+following scenario demonstrates this issue:
+
+CPU 0 (get_signal path)                CPU 1 (freezer.state reader)
+try_to_freeze                  read freezer.state
+__refrigerator                 freezer_read
+                               update_if_frozen
+WRITE_ONCE(current->__state, TASK_FROZEN);
+                               ...
+                               /* Task is now marked frozen */
+                               /* frozen(task) == true */
+                               /* Assuming other tasks are frozen */
+                               freezer->state |= CGROUP_FROZEN;
+/* freezing(current) returns false */
+/* because cgroup is frozen (not freezing) */
+break out
+__set_current_state(TASK_RUNNING);
+/* Bug: Task resumes running when it should remain frozen */
+
+The existing !frozen(p) check in __thaw_task makes the
+WARN_ON_ONCE(freezing(p)) warning redundant. Removing this warning enables
+reverting the commit cff5f49d433f ("cgroup_freezer: cgroup_freezing: Check
+if not frozen") to resolve the issue.
+
+The warning has been removed in the previous patch. This patch revert the
+commit cff5f49d433f ("cgroup_freezer: cgroup_freezing: Check if not
+frozen") to complete the fix.

+Subject: riscv: Enable interrupt during exception handling
+
+From: Nam Cao <namcao@linutronix.de>
+
+[ Upstream commit 969f028bf2c40573ef18061f702ede3ebfe12b42 ]
+
+force_sig_fault() takes a spinlock, which is a sleeping lock with
+CONFIG_PREEMPT_RT=y. However, exception handling calls force_sig_fault()
+with interrupt disabled, causing a sleeping in atomic context warning.
+
+This can be reproduced using userspace programs such as:
+    int main() { asm ("ebreak"); }
+or
+    int main() { asm ("unimp"); }
+
+There is no reason that interrupt must be disabled while handling
+exceptions from userspace.
+
+Enable interrupt while handling user exceptions. This also has the added
+benefit of avoiding unnecessary delays in interrupt handling.

+Running lwt_dst_cache_ref_loop.sh in selftest with KASAN triggers

+
+rpl_do_srh_inline() fetches ipv6_hdr(skb) and accesses it after
+skb_cow_head(), which is illegal as the header could be freed then.

+Subject: rxrpc: Fix recv-recv race of completed call
+
+From: David Howells <dhowells@redhat.com>
+
+[ Upstream commit 962fb1f651c2cf2083e0c3ef53ba69e3b96d3fbc ]
+
+If a call receives an event (such as incoming data), the call gets placed
+on the socket's queue and a thread in recvmsg can be awakened to go and
+process it.  Once the thread has picked up the call off of the queue,
+further events will cause it to be requeued, and once the socket lock is
+dropped (recvmsg uses call->user_mutex to allow the socket to be used in
+parallel), a second thread can come in and its recvmsg can pop the call off
+the socket queue again.
+
+In such a case, the first thread will be receiving stuff from the call and
+the second thread will be blocked on call->user_mutex.  The first thread
+can, at this point, process both the event that it picked call for and the
+event that the second thread picked the call for and may see the call
+terminate - in which case the call will be "released", decoupling the call
+from the user call ID assigned to it (RXRPC_USER_CALL_ID in the control
+message).
+
+The first thread will return okay, but then the second thread will wake up
+holding the user_mutex and, if it sees that the call has been released by
+the first thread, it will BUG thusly:
+
+       kernel BUG at net/rxrpc/recvmsg.c:474!
+
+Fix this by just dequeuing the call and ignoring it if it is seen to be
+already released.  We can't tell userspace about it anyway as the user call
+ID has become stale.

+
+[ Upstream commit e9c0b96ec0a34fcacdf9365713578d83cecac34c ]
+
+Under some circumstances, such as when a server socket is closing, ABORT
+packets will be generated in response to incoming packets.  Unfortunately,
+this also may include generating aborts in response to incoming aborts -
+which may cause a cycle.  It appears this may be made possible by giving
+the client a multicast address.
+
+Fix this such that rxrpc_reject_packet() will refuse to generate aborts in
+response to aborts.

+Subject: smb: client: fix use-after-free in cifs_oplock_break
+
+From: Wang Zhaolong <wangzhaolong@huaweicloud.com>
+
+[ Upstream commit 705c79101ccf9edea5a00d761491a03ced314210 ]
+
+A race condition can occur in cifs_oplock_break() leading to a
+use-after-free of the cinode structure when unmounting:
+
+  cifs_oplock_break()
+    _cifsFileInfo_put(cfile)
+      cifsFileInfo_put_final()
+        cifs_sb_deactive()
+          [last ref, start releasing sb]
+            kill_sb()
+              kill_anon_super()
+                generic_shutdown_super()
+                  evict_inodes()
+                    dispose_list()
+                      evict()
+                        destroy_inode()
+                          call_rcu(&inode->i_rcu, i_callback)
+    spin_lock(&cinode->open_file_lock)  <- OK
+                            [later] i_callback()
+                              cifs_free_inode()
+                                kmem_cache_free(cinode)
+    spin_unlock(&cinode->open_file_lock)  <- UAF
+    cifs_done_oplock_break(cinode)       <- UAF
+
+The issue occurs when umount has already released its reference to the
+superblock. When _cifsFileInfo_put() calls cifs_sb_deactive(), this
+releases the last reference, triggering the immediate cleanup of all
+inodes under RCU. However, cifs_oplock_break() continues to access the
+cinode after this point, resulting in use-after-free.
+
+Fix this by holding an extra reference to the superblock during the
+entire oplock break operation. This ensures that the superblock and
+its inodes remain valid until the oplock break completes.

+Subject: smc: Fix various oops due to inet_sock type confusion.
+
+From: Kuniyuki Iwashima <kuniyu@google.com>
+
+[ Upstream commit 60ada4fe644edaa6c2da97364184b0425e8aeaf5 ]
+
+syzbot reported weird splats [0][1] in cipso_v4_sock_setattr() while
+freeing inet_sk(sk)->inet_opt.
+
+The address was freed multiple times even though it was read-only memory.
+
+cipso_v4_sock_setattr() did nothing wrong, and the root cause was type
+confusion.
+
+The cited commit made it possible to create smc_sock as an INET socket.
+
+The issue is that struct smc_sock does not have struct inet_sock as the
+first member but hijacks AF_INET and AF_INET6 sk_family, which confuses
+various places.
+
+In this case, inet_sock.inet_opt was actually smc_sock.clcsk_data_ready(),
+which is an address of a function in the text segment.
+
+  $ pahole -C inet_sock vmlinux
+  struct inet_sock {
+  ...
+          struct ip_options_rcu *    inet_opt;             /*   784     8 */
+
+  $ pahole -C smc_sock vmlinux
+  struct smc_sock {
+  ...
+          void                       (*clcsk_data_ready)(struct sock *); /*   784     8 */
+
+The same issue for another field was reported before. [2][3]
+
+At that time, an ugly hack was suggested [4], but it makes both INET
+and SMC code error-prone and hard to change.
+
+Also, yet another variant was fixed by a hacky commit 98d4435efcbf3
+("net/smc: prevent NULL pointer dereference in txopt_get").
+
+Instead of papering over the root cause by such hacks, we should not
+allow non-INET socket to reuse the INET infra.
+
+Let's add inet_sock as the first member of smc_sock.

+
+After recent changes in net-next TCP compacts skbs much more
+aggressively. This unearthed a bug in TLS where we may try
+to operate on an old skb when checking if all skbs in the
+queue have matching decrypt state and geometry.
+
+    BUG: KASAN: slab-use-after-free in tls_strp_check_rcv+0x898/0x9a0 [tls]
+    (net/tls/tls_strp.c:436 net/tls/tls_strp.c:530 net/tls/tls_strp.c:544)

+Subject: virtio-net: fix recursived rtnl_lock() during probe()
+
+From: Zigit Zo <zuozhijie@bytedance.com>
+
+[ Upstream commit be5dcaed694e4255dc02dd0acfe036708c535def ]
+
+The deadlock appears in a stack trace like:
+
+  virtnet_probe()
+    rtnl_lock()
+    virtio_config_changed_work()
+      netdev_notify_peers()
+        rtnl_lock()
+
+It happens if the VMM sends a VIRTIO_NET_S_ANNOUNCE request while the
+virtio-net driver is still probing.
+
+The config_work in probe() will get scheduled until virtnet_open() enables
+the config change notification via virtio_config_driver_enable().

+Subject: wifi: cfg80211: remove scan request n_channels counted_by
+
+From: Johannes Berg <johannes.berg@intel.com>
+
+[ Upstream commit 444020f4bf06fb86805ee7e7ceec0375485fd94d ]
+
+This reverts commit e3eac9f32ec0 ("wifi: cfg80211: Annotate struct
+cfg80211_scan_request with __counted_by").
+
+This really has been a completely failed experiment. There were
+no actual bugs found, and yet at this point we already have four
+"fixes" to it, with nothing to show for but code churn, and it
+never even made the code any safer.
+
+In all of the cases that ended up getting "fixed", the structure
+is also internally inconsistent after the n_channels setting as
+the channel list isn't actually filled yet. You cannot scan with
+such a structure, that's just wrong. In mac80211, the struct is
+also reused multiple times, so initializing it once is no good.
+
+Some previous "fixes" (e.g. one in brcm80211) are also just setting
+n_channels before accessing the array, under the assumption that the
+code is correct and the array can be accessed, further showing that
+the whole thing is just pointless when the allocation count and use
+count are not separate.
+
+If we really wanted to fix it, we'd need to separately track the
+number of channels allocated and the number of channels currently
+used, but given that no bugs were found despite the numerous syzbot
+reports, that'd just be a waste of time.
+
+Remove the __counted_by() annotation. We really should also remove
+a number of the n_channels settings that are setting up a structure
+that's inconsistent, but that can wait.
