+Subject: IB/mlx5: Set and get correct qp_num for a DCT QP
+
+From: Mark Zhang <markzhang@nvidia.com>
+
+[ Upstream commit 12d044770e12c4205fa69535b4fa8a9981fea98f ]
+
+When a DCT QP is created on an active lag, it's dctc.port is assigned
+in a round-robin way, which is from 1 to dev->lag_port. In this case
+when querying this QP, we may get qp_attr.port_num > 2.
+Fix this by setting qp->port when modifying a DCT QP, and read port_num
+from qp->port instead of dctc.port when querying it.

+Subject: landlock: Fix non-TCP sockets restriction
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Mikhail Ivanov <ivanov.mikhail1@huawei-partners.com>
+
+[ Upstream commit 854277e2cc8c75dc3c216c82e72523258fcf65b9 ]
+
+Use sk_is_tcp() to check if socket is TCP in bind(2) and connect(2)
+hooks.
+
+SMC, MPTCP, SCTP protocols are currently restricted by TCP access
+rights. The purpose of TCP access rights is to provide control over
+ports that can be used by userland to establish a TCP connection.
+Therefore, it is incorrect to deny bind(2) and connect(2) requests for a
+socket of another protocol.
+
+However, SMC, MPTCP and RDS implementations use TCP internal sockets to
+establish communication or even to exchange packets over a TCP
+connection [1]. Landlock rules that configure bind(2) and connect(2)
+usage for TCP sockets should not cover requests for sockets of such
+protocols. These protocols have different set of security issues and
+security properties, therefore, it is necessary to provide the userland
+with the ability to distinguish between them (eg. [2]).
+
+Control over TCP connection used by other protocols can be achieved with
+upcoming support of socket creation control [3].

+While it is uncommon for delegations to be held while O_DIRECT writes

+Subject: NFSv4: Fix a deadlock when recovering state on a sillyrenamed file
+
+From: Trond Myklebust <trond.myklebust@hammerspace.com>
+
+[ Upstream commit 8f8df955f078e1a023ee55161935000a67651f38 ]
+
+If the file is sillyrenamed, and slated for delete on close, it is
+possible for a server reboot to triggeer an open reclaim, with can again
+race with the application call to close(). When that happens, the call
+to put_nfs_open_context() can trigger a synchronous delegreturn call
+which deadlocks because it is not marked as privileged.
+
+Instead, ensure that the call to nfs4_inode_return_delegation_on_close()
+catches the delegreturn, and schedules it asynchronously.

+Subject: RDMA/bnxt_re: Allocate dev_attr information dynamically
+
+From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>
+
+[ Upstream commit 9264cd6aa8f194753507cb6e1f444141e7c79f48 ]
+
+In order to optimize the size of driver private structure,
+the memory for dev_attr is allocated dynamically during the
+chip context initialization. In order to make certain runtime
+decisions, store dev_attr in the qplib_res structure.

+Subject: RDMA/hns: Fix mbox timing out by adding retry mechanism
+
+From: Junxian Huang <huangjunxian6@hisilicon.com>
+
+[ Upstream commit 9747c0c7791d4a5a62018a0c9c563dd2e6f6c1c0 ]
+
+If a QP is modified to error state and a flush CQE process is triggered,
+the subsequent QP destruction mbox can still be successfully posted but
+will be blocked in HW until the flush CQE process finishes. This causes
+further mbox posting timeouts in driver. The blocking time is related
+to QP depth. Considering an extreme case where SQ depth and RQ depth
+are both 32K, the blocking time can reach about 135ms.
+
+This patch adds a retry mechanism for mbox posting. For each try, FW
+waits 15ms for HW to complete the previous mbox, otherwise return a
+timeout error code to driver. Counting other time consumption in FW,
+set 8 tries for mbox posting and a 5ms time gap before each retry to
+increase to a sufficient timeout limit.

+Subject: RDMA/mlx5: Fix a race for DMABUF MR which can lead to CQE with error
+
+From: Yishai Hadas <yishaih@nvidia.com>
+
+[ Upstream commit cc668a11e6ac8adb0e016711080d3f314722cc91 ]
+
+This patch addresses a potential race condition for a DMABUF MR that can
+result in a CQE with an error on the UMR QP.
+
+During the __mlx5_ib_dereg_mr() flow, the following sequence of calls
+occurs:
+mlx5_revoke_mr()
+mlx5r_umr_revoke_mr()
+mlx5r_umr_post_send_wait()
+At this point, the lkey is freed from the hardware's perspective.
+
+However, concurrently, mlx5_ib_dmabuf_invalidate_cb() might be triggered
+by another task attempting to invalidate the MR having that freed lkey.
+
+Since the lkey has already been freed, this can lead to a CQE error,
+causing the UMR QP to enter an error state.
+
+To resolve this race condition, the dma_resv_lock() which was hold as
+part of the mlx5_ib_dmabuf_invalidate_cb() is now also acquired as part
+of the mlx5_revoke_mr() scope.
+
+Upon a successful revoke, we set umem_dmabuf->private which points to
+that MR to NULL, preventing any further invalidation attempts on its
+lkey.

+
+Memory regions (MR) of type DM (device memory) do not have an associated
+umem.
+
+In the __mlx5_ib_dereg_mr() -> mlx5_free_priv_descs() flow, the code
+incorrectly takes the wrong branch, attempting to call

+The issue is resolved by properly accounting for the DM type and
+ensuring the correct branch is selected in mlx5_free_priv_descs().

+Fix the destroy_unused_implicit_child_mr() to prevent hanging during
+parent deregistration as of below [1].
+
+Upon entering destroy_unused_implicit_child_mr(), the reference count
+for the implicit MR parent is incremented using:
+refcount_inc_not_zero().
+
+A corresponding decrement must be performed if
+free_implicit_child_mr_work() is not called.

+The code has been updated to properly manage the reference count that
+was incremented.

+Subject: RDMA/mlx5: Fix the recovery flow of the UMR QP
+
+From: Yishai Hadas <yishaih@nvidia.com>
+
+[ Upstream commit d97505baea64d93538b16baf14ce7b8c1fbad746 ]
+
+This patch addresses an issue in the recovery flow of the UMR QP,
+ensuring tasks do not get stuck, as highlighted by the call trace [1].
+
+During recovery, before transitioning the QP to the RESET state, the
+software must wait for all outstanding WRs to complete.
+
+Failing to do so can cause the firmware to skip sending some flushed
+CQEs with errors and simply discard them upon the RESET, as per the IB
+specification.
+
+This race condition can result in lost CQEs and tasks becoming stuck.
+
+To resolve this, the patch sends a final WR which serves only as a
+barrier before moving the QP state to RESET.
+
+Once a CQE is received for that final WR, it guarantees that no
+outstanding WRs remain, making it safe to transition the QP to RESET and
+subsequently back to RTS, restoring proper functionality.
+
+Note:
+For the barrier WR, we simply reuse the failed and ready WR.
+Since the QP is in an error state, it will only receive
+IB_WC_WR_FLUSH_ERR. However, as it serves only as a barrier we don't
+care about its status.

+Subject: scsi: core: Clear driver private data when retrying request
+
+From: Ye Bin <yebin10@huawei.com>
+
+[ Upstream commit dce5c4afd035e8090a26e5d776b1682c0e649683 ]
+
+After commit 1bad6c4a57ef ("scsi: zero per-cmd private driver data for each
+MQ I/O"), the xen-scsifront/virtio_scsi/snic drivers all removed code that
+explicitly zeroed driver-private command data.
+
+In combination with commit 464a00c9e0ad ("scsi: core: Kill DRIVER_SENSE"),
+after virtio_scsi performs a capacity expansion, the first request will
+return a unit attention to indicate that the capacity has changed. And then
+the original command is retried. As driver-private command data was not
+cleared, the request would return UA again and eventually time out and fail.
+
+Zero driver-private command data when a request is retried.
+
+Fixes: f7de50da1479 ("scsi: xen-scsifront: Remove code that zeroes driver-private command data")
+Fixes: c2bb87318baa ("scsi: virtio_scsi: Remove code that zeroes driver-private command data")

+
+From: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org>
+
+[ Upstream commit fe06b7c07f3fbcce2a2ca6f7b0d543b5699ea00f ]
+
+Commit bb9850704c04 ("scsi: ufs: core: Honor runtime/system PM levels if
+set by host controller drivers") introduced the check for setting default
+PM levels only if the levels are uninitialized by the host controller
+drivers. But it missed the fact that the levels could be initialized to 0
+(UFS_PM_LVL_0) on purpose by the controller drivers. Even though none of
+the drivers are doing so now, the logic should be fixed irrespectively.
+
+So set the default levels unconditionally before calling ufshcd_hba_init()
+API which initializes the controller drivers. It ensures that the
+controller drivers could override the default levels if required.

+From: Benjamin Coddington <bcodding@redhat.com>
+
+[ Upstream commit 7a2f6f7687c5f7083a35317cddec5ad9fa491443 ]
+
+If the TLS handshake attempt returns -ETIMEDOUT, we currently translate
+that error into -EACCES. This becomes problematic for cases where the RPC
+layer is attempting to re-connect in paths that don't resonably handle
+-EACCES, for example: writeback. The RPC layer can handle -ETIMEDOUT quite
+well, however - so if the handshake returns this error let's just pass it
+along.

+Subject: SUNRPC: Prevent looping due to rpc_signal_task() races
+
+From: Trond Myklebust <trond.myklebust@hammerspace.com>
+
+[ Upstream commit 5bbd6e863b15a85221e49b9bdb2d5d8f0bb91f3d ]
+
+If rpc_signal_task() is called while a task is in an rpc_call_done()
+callback function, and the latter calls rpc_restart_call(), the task can
+end up looping due to the RPC_TASK_SIGNALLED flag being set without the
+tk_rpc_status being set.
+Removing the redundant mechanism for signalling the task fixes the
+looping behaviour.

+Subject: sunrpc: suppress warnings for unused procfs functions
+
+From: Arnd Bergmann <arnd@arndb.de>
+
+[ Upstream commit 1f7a4f98c11fbeb18ed21f3b3a497e90a50ad2e0 ]
+
+There is a warning about unused variables when building with W=1 and no procfs:
+
+net/sunrpc/cache.c:1660:30: error: 'cache_flush_proc_ops' defined but not used [-Werror=unused-const-variable=]
+ 1660 | static const struct proc_ops cache_flush_proc_ops = {
+ | ^~~~~~~~~~~~~~~~~~~~
+net/sunrpc/cache.c:1622:30: error: 'content_proc_ops' defined but not used [-Werror=unused-const-variable=]
+ 1622 | static const struct proc_ops content_proc_ops = {
+ | ^~~~~~~~~~~~~~~~
+net/sunrpc/cache.c:1598:30: error: 'cache_channel_proc_ops' defined but not used [-Werror=unused-const-variable=]
+ 1598 | static const struct proc_ops cache_channel_proc_ops = {
+ | ^~~~~~~~~~~~~~~~~~~~~~
+
+These are used inside of an #ifdef, so replacing that with an
+IS_ENABLED() check lets the compiler see how they are used while
+still dropping them during dead code elimination.
