      Pull vfs fixes from Christian Brauner:
      
       - Avoid calling back into LSMs from vfs_getattr_nosec() calls.
      
         IMA used to query inode properties accessing raw inode fields without
         dedicated helpers. That was finally fixed a few releases ago by
         forcing IMA to use vfs_getattr_nosec() helpers.
      
         The goal of the vfs_getattr_nosec() helper is to query for attributes
         without calling into the LSM layer which would be quite problematic
         because incredibly IMA is called from __fput()...
      
           __fput()
             -> ima_file_free()
      
         What it does is to call back into the filesystem to update the file's
         IMA xattr. Querying the inode without using vfs_getattr_nosec() meant
         that IMA didn't handle stacking filesystems such as overlayfs
         correctly. So the switch to vfs_getattr_nosec() is quite correct. But
         the switch to vfs_getattr_nosec() revealed another bug when used on
         stacking filesystems:
      
           __fput()
             -> ima_file_free()
                -> vfs_getattr_nosec()
                   -> i_op->getattr::ovl_getattr()
                      -> vfs_getattr()
                         -> i_op->getattr::$WHATEVER_UNDERLYING_FS_getattr()
                            -> security_inode_getattr() # calls back into LSMs
      
         Now, if that __fput() happens from task_work_run() of an exiting task
         current->fs and various other pointer could already be NULL. So
         anything in the LSM layer relying on that not being NULL would be
         quite surprised.
      
         Fix that by passing the information that this is a security request
         through to the stacking filesystem by adding a new internal
         ATT_GETATTR_NOSEC flag. Now the callchain becomes:
      
           __fput()
             -> ima_file_free()
                -> vfs_getattr_nosec()
                   -> i_op->getattr::ovl_getattr()
                      -> if (AT_GETATTR_NOSEC)
                                vfs_getattr_nosec()
                         else
                                vfs_getattr()
                         -> i_op->getattr::$WHATEVER_UNDERLYING_FS_getattr()
      
       - Fix a bug introduced with the iov_iter rework from last cycle.
      
         This broke /proc/kcore by copying too much and without the correct
         offset.
      
       - Add a missing NULL check when allocating the root inode in
         autofs_fill_super().
      
       - Fix stable writes for multi-device filesystems (xfs, btrfs etc) and
         the block device pseudo filesystem.
      
         Stable writes used to be a superblock flag only, making it a per
         filesystem property. Add an additional AS_STABLE_WRITES mapping flag
         to allow for fine-grained control.
      
       - Ensure that offset_iterate_dir() returns 0 after reaching the end of
         a directory so it adheres to getdents() convention.

      We don't support CRUD-inspired message types in YNL too well.
      One aspect that currently trips us up is the fact that single
      message ID can be used in multiple commands (as the response).
      This leads to duplicate entries in the id-to-string tables:

      syzkaller discovered that if tls_sw_splice_eof() is executed as part of
      sendfile() when the plaintext/ciphertext sk_msg are empty, the send path
      gets confused because the empty ciphertext buffer does not have enough
      space for the encryption overhead. This causes tls_push_record() to go on
      the `split = true` path (which is only supposed to be used when interacting
      with an attached BPF program), and then get further confused and hit the
      tls_merge_open_record() path, which then assumes that there must be at
      least one populated buffer element, leading to a NULL deref.
      
      It is possible to have empty plaintext/ciphertext buffers if we previously
      bailed from tls_sw_sendmsg_locked() via the tls_trim_both_msgs() path.
      tls_sw_push_pending_record() already handles this case correctly; let's do
      the same check in tls_sw_splice_eof().

      ====================
      ice: restore timestamp config after reset
      
      Jake Keller says:
      
      We recently discovered during internal validation that the ice driver has
      not been properly restoring Tx timestamp configuration after a device reset,
      which resulted in application failures after a device reset.
      
      After some digging, it turned out this problem is two-fold. Since the
      introduction of the PTP support the driver has been clobbering the storage
      of the current timestamp configuration during reset. Thus after a reset, the
      driver will no longer perform Tx or Rx timestamps, and will report
      timestamp configuration as disabled if SIOCGHWTSTAMP ioctl is issued.
      
      In addition, the recently merged auxiliary bus support code missed that
      PFINT_TSYN_MSK must be reprogrammed on the clock owner for E822 devices.
      Failure to restore this register configuration results in the driver no
      longer responding to interrupts from other ports. Depending on the traffic
      pattern, this can either result in increased latency responding to
      timestamps on the non-owner ports, or it can result in the driver never
      reporting any timestamps. The configuration of PFINT_TSYN_MSK was only done
      during initialization. Due to this, the Tx timestamp issue persists even if
      userspace reconfigures timestamping.
      
      This series fixes both issues, as well as removes a redundant Tx ring field
      since we can rely on the skb flag as the primary detector for a Tx timestamp
      request.
      
      Note that I don't think this series will directly apply to older stable
      releases (even v6.6) as we recently refactored a lot of the PTP code to
      support auxiliary bus. Patch 2/3 only matters for the post-auxiliary bus
      implementation. The principle of patch 1/3 and 3/3 could apply as far back
      as the initial PTP support, but I don't think it will apply cleanly as-is.

      ice: restore timestamp configuration after device reset · 77580179
      Jacob Keller authored
      The driver calls ice_ptp_cfg_timestamp() during ice_ptp_prepare_for_reset()
      to disable timestamping while the device is resetting. This operation
      destroys the user requested configuration. While the driver does call
      ice_ptp_cfg_timestamp in ice_rebuild() to restore some hardware settings
      after a reset, it unconditionally passes true or false, resulting in
      failure to restore previous user space configuration.
      
      This results in a device reset forcibly disabling timestamp configuration
      regardless of current user settings.
      
      This was not detected previously due to a quirk of the LinuxPTP ptp4l
      application. If ptp4l detects a missing timestamp, it enters a fault state
      and performs recovery logic which includes executing SIOCSHWTSTAMP again,
      restoring the now accidentally cleared configuration.
      
      Not every application does this, and for these applications, timestamps
      will mysteriously stop after a PF reset, without being restored until an
      application restart.
      
      Fix this by replacing ice_ptp_cfg_timestamp() with two new functions:
      
      1) ice_ptp_disable_timestamp_mode() which unconditionally disables the
         timestamping logic in ice_ptp_prepare_for_reset() and ice_ptp_release()
      
      2) ice_ptp_restore_timestamp_mode() which calls
         ice_ptp_restore_tx_interrupt() to restore Tx timestamping configuration,
         calls ice_set_rx_tstamp() to restore Rx timestamping configuration, and
         issues an immediate TSYN_TX interrupt to ensure that timestamps which
         may have occurred during the device reset get processed.
      
      Modify the ice_ptp_set_timestamp_mode to directly save the user
      configuration and then call ice_ptp_restore_timestamp_mode. This way, reset
      no longer destroys the saved user configuration.
      
      This obsoletes the ice_set_tx_tstamp() function which can now be safely
      removed.
      
      With this change, all devices should now restore Tx and Rx timestamping
      functionality correctly after a PF reset without application intervention.

      ice: unify logic for programming PFINT_TSYN_MSK · 7d606a1e
      Jacob Keller authored
      Commit d938a8cc ("ice: Auxbus devices & driver for E822 TS") modified
      how Tx timestamps are handled for E822 devices. On these devices, only the
      clock owner handles reading the Tx timestamp data from firmware. To do
      this, the PFINT_TSYN_MSK register is modified from the default value to one
      which enables reacting to a Tx timestamp on all PHY ports.
      
      The driver currently programs PFINT_TSYN_MSK in different places depending
      on whether the port is the clock owner or not. For the clock owner, the
      PFINT_TSYN_MSK value is programmed during ice_ptp_init_owner just before
      calling ice_ptp_tx_ena_intr to program the PHY ports.
      
      For the non-clock owner ports, the PFINT_TSYN_MSK is programmed during
      ice_ptp_init_port.
      
      If a large enough device reset occurs, the PFINT_TSYN_MSK register will be
      reset to the default value in which only the PHY associated directly with
      the PF will cause the Tx timestamp interrupt to trigger.
      
      The driver lacks logic to reprogram the PFINT_TSYN_MSK register after a
      device reset. For the E822 device, this results in the PF no longer
      responding to interrupts for other ports. This results in failure to
      deliver Tx timestamps to user space applications.
      
      Rename ice_ptp_configure_tx_tstamp to ice_ptp_cfg_tx_interrupt, and unify
      the logic for programming PFINT_TSYN_MSK and PFINT_OICR_ENA into one place.
      This function will program both registers according to the combination of
      user configuration and device requirements.
      
      This ensures that PFINT_TSYN_MSK is always restored when we configure the
      Tx timestamp interrupt.

      ice: remove ptp_tx ring parameter flag · 0ffb08b1
      Jacob Keller authored
      Before performing a Tx timestamp in ice_stamp(), the driver checks a ptp_tx
      ring variable to see if timestamping is enabled on that ring. This value is
      set for all rings whenever userspace configures Tx timestamping.
      
      Ostensibly this was done to avoid wasting cycles checking other fields when
      timestamping has not been enabled. However, for Tx timestamps we already
      get an individual per-SKB flag indicating whether userspace wants to
      request a timestamp on that packet. We do not gain much by also having
      a separate flag to check for whether timestamping was enabled.
      
      In fact, the driver currently fails to restore the field after a PF reset.
      Because of this, if a PF reset occurs, timestamps will be disabled.
      
      Since this flag doesn't add value in the hotpath, remove it and always
      provide a timestamp if the SKB flag has been set.
      
      A following change will fix the reset path to properly restore user
      timestamping configuration completely.
      
      This went unnoticed for some time because one of the most common
      applications using Tx timestamps, ptp4l, will reconfigure the socket as
      part of its fault recovery logic.

      octeontx2-pf: Fix ntuple rule creation to direct packet to VF with higher Rx queue than its PF · 4aa1d8f8
      Suman Ghosh authored
      It is possible to add a ntuple rule which would like to direct packet to
      a VF whose number of queues are greater/less than its PF's queue numbers.
      For example a PF can have 2 Rx queues but a VF created on that PF can have
      8 Rx queues. As of today, ntuple rule will reject rule because it is
      checking the requested queue number against PF's number of Rx queues.
      As a part of this fix if the action of a ntuple rule is to move a packet
      to a VF's queue then the check is removed. Also, a debug information is
      printed to aware user that it is user's responsibility to cross check if
      the requested queue number on that VF is a valid one.

      nvme: tcp: fix compile-time checks for TLS mode · 0e6c4fe7
      Arnd Bergmann authored
      
      
      When CONFIG_NVME_KEYRING is enabled as a loadable module, but the TCP
      host code is built-in, it fails to link:
      
      arm-linux-gnueabi-ld: drivers/nvme/host/tcp.o: in function `nvme_tcp_setup_ctrl':
      tcp.c:(.text+0x1940): undefined reference to `nvme_tls_psk_default'
      
      The problem is that the compile-time conditionals are inconsistent here,
      using a mix of #ifdef CONFIG_NVME_TCP_TLS, IS_ENABLED(CONFIG_NVME_TCP_TLS)
      and IS_ENABLED(CONFIG_NVME_KEYRING) checks, with CONFIG_NVME_KEYRING
      controlling whether the implementation is actually built.
      
      Change it to use IS_ENABLED(CONFIG_NVME_KEYRING) checks consistently,
      which should help readability and make it less error-prone. Combining
      it with the check for the ctrl->opts->tls flag lets the compiler drop
      all the TLS code in configurations without this feature, which also
      helps runtime behavior in addition to avoiding the link failure.
      
      To make it possible for the compiler to build the dead code, both
      the tls_handshake_timeout variable and the TLS specific members
      of nvme_tcp_queue need to be moved out of the #ifdef block as well,
      but at least the former of these gets optimized out again.

      Arnd Bergmann authored
      
      
      When the NVME target code is built-in but its TCP frontend is a loadable
      module, enabling keyring support causes a link failure:
      
      x86_64-linux-ld: vmlinux.o: in function `nvmet_ports_make':
      configfs.c:(.text+0x100a211): undefined reference to `nvme_keyring_id'
      
      The problem is that CONFIG_NVME_TARGET_TCP_TLS is a 'bool' symbol that
      depends on the tristate CONFIG_NVME_TARGET_TCP, so any 'select' from
      it inherits the state of the tristate symbol rather than the intended
      CONFIG_NVME_TARGET one that contains the actual call.
      
      The same thing is true for CONFIG_KEYS, which itself is required for
      NVME_KEYRING.

      In configurations without CONFIG_NVME_TARGET_TCP_TLS, the keyring
      code might not be available, or using it will result in a runtime
      failure:
      
      x86_64-linux-ld: vmlinux.o: in function `nvmet_ports_make':
      configfs.c:(.text+0x100a211): undefined reference to `nvme_keyring_id'
      
      Add a check to ensure we only check the keyring if there is a chance
      of it being used, which avoids both the runtime and link-time
      problems.

      asm-generic: qspinlock: fix queued_spin_value_unlocked() implementation · 125b0bb9
      Linus Torvalds authored
      We really don't want to do atomic_read() or anything like that, since we
      already have the value, not the lock.  The whole point of this is that
      we've loaded the lock from memory, and we want to check whether the
      value we loaded was a locked one or not.
      
      The main use of this is the lockref code, which loads both the lock and
      the reference count in one atomic operation, and then works on that
      combined value.  With the atomic_read(), the compiler would pointlessly
      spill the value to the stack, in order to then be able to read it back
      "atomically".
      
      This is the qspinlock version of commit c6f4a900
      
       ("asm-generic:
      ticket-lock: Optimize arch_spin_value_unlocked()") which fixed this same
      bug for ticket locks.

      Hannes Reinecke authored
      Stopping keep-alive not only stops the keep-alive workqueue,
      but also needs to be synchronized with I/O termination as we
      must not send a keep-alive command after all I/O had been
      terminated.
      So to avoid any regressions move the call to stop_keep_alive()
      back to its original position and ensure that keep-alive is
      correctly stopped failing to setup the admin queue.

      Revert "net: r8169: Disable multicast filter for RTL8168H and RTL8107E" · 6a263102
      Heiner Kallweit authored
      This reverts commit efa5f131
      
      .
      
      I couldn't reproduce the reported issue. What I did, based on a pcap
      packet log provided by the reporter:
      - Used same chip version (RTL8168h)
      - Set MAC address to the one used on the reporters system
      - Replayed the EAPOL unicast packet that, according to the reporter,
        was filtered out by the mc filter.
      The packet was properly received.
      
      Therefore the root cause of the reported issue seems to be somewhere
      else. Disabling mc filtering completely for the most common chip
      version is a quite big hammer. Therefore revert the change and wait
      for further analysis results from the reporter.

      net/smc: avoid data corruption caused by decline · e6d71b43
      D. Wythe authored
      We found a data corruption issue during testing of SMC-R on Redis
      applications.
      
      The benchmark has a low probability of reporting a strange error as
      shown below.
      
      "Error: Protocol error, got "\xe2" as reply type byte"
      
      Finally, we found that the retrieved error data was as follows:
      
      0xE2 0xD4 0xC3 0xD9 0x04 0x00 0x2C 0x20 0xA6 0x56 0x00 0x16 0x3E 0x0C
      0xCB 0x04 0x02 0x01 0x00 0x00 0x20 0x00 0x00 0x00 0x00 0x00 0x00 0x00
      0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0xE2
      
      It is quite obvious that this is a SMC DECLINE message, which means that
      the applications received SMC protocol message.
      We found that this was caused by the following situations:
      
      client                  server
              ¦  clc proposal
              ------------->
              ¦  clc accept
              <-------------
              ¦  clc confirm
              ------------->
      wait llc confirm
      			send llc confirm
              ¦failed llc confirm
              ¦   x------
      (after 2s)timeout
                              wait llc confirm rsp
      
      wait decline
      
      (after 1s) timeout
                              (after 2s) timeout
              ¦   decline
              -------------->
              ¦   decline
              <--------------
      
      As a result, a decline message was sent in the implementation, and this
      message was read from TCP by the already-fallback connection.
      
      This patch double the client timeout as 2x of the server value,
      With this simple change, the Decline messages should never cross or
      collide (during Confirm link timeout).
      
      This issue requires an immediate solution, since the protocol updates
      involve a more long-term solution.

      HID: multitouch: Add quirk for HONOR GLO-GXXX touchpad · 9ffccb69
      Aoba K authored
      
      
      Honor MagicBook 13 2023 has a touchpad which do not switch to the multitouch
      mode until the input mode feature is written by the host.  The touchpad do
      report the input mode at touchpad(3), while itself working under mouse mode. As
      a workaround, it is possible to call MT_QUIRE_FORCE_GET_FEATURE to force set
      feature in mt_set_input_mode for such device.
      
      The touchpad reports as BLTP7853, which cannot retrive any useful manufacture
      information on the internel by this string at present.  As the serial number of
      the laptop is GLO-G52, while DMI info reports the laptop serial number as
      GLO-GXXX, this workaround should applied to all models which has the GLO-GXXX.
