      Pull drm fixes from Dave Airlie:
       "This is the weekly drm fixes. Non-drivers there is a fbdev/sparc fix,
        syncobj, ttm and buddy fixes.
      
        On the driver side, ivpu, meson, i915 have a small fix each. Then
        amdgpu and xe have a bunch. Nouveau has some minor uapi additions to
        give userspace some useful info along with a Kconfig change to allow
        the new GSP firmware paths to be used by default on the GPUs it
        supports.
      
        Seems about the usual amount for this time of release cycle.
      
        fbdev:
         - fix sparc undefined reference
      
        syncobj:
         - fix sync obj fence waiting
         - handle NULL fence in syncobj eventfd code

         - fix invalid free
      
        buddy:
         - fix list handling
         - fix 32-bit build
      
        meson:
         - don't remove bridges from other drivers
      
        nouveau:
         - fix build warnings
         - add two minor info parameters
         - add a Kconfig to allow GSP by default on some GPUs
      
        ivpu:
         - allow fw to do initial tile config
      
        i915:
         - fix TV mode
      
        amdgpu:
         - Suspend/resume fixes
         - Backlight error fix
         - DCN 3.5 fixes
         - Misc fixes
      
        xe:
         - Remove support for persistent exec_queues
         - Drop a reduntant sysfs newline printout
         - A three-patch fix for a VM_BIND rebind optimization path
         - Fix a modpost warning on an xe KUNIT module"

      Pull ata fixes from Niklas Cassel:
      
       - Do not try to set a sleeping device to standby. Sleep is a deeper
         sleep state than standby, and needs a reset to wake up the drive. A
         system resume will reset the port. Sending a command other than reset
         to a sleeping device is not wise, as the command will timeout (Damien
         Le Moal)
      
       - Do not try to put a device to standby twice during system shutdown.
         ata_dev_power_set_standby() is currently called twice during
         shutdown, once after the scsi device is removed, and another when
         ata_pci_shutdown_one() executes. Modify ata_dev_power_set_standby()
         to do nothing if the device is already in standby (Damien Le Moal)
      
       - Add a quirk for ASM1064 to fixup the number of implemented ports. We
         probe all ports that the hardware reports to be implemented. Probing
         ports that are not implemented causes significantly increased boot
         time (Andrey Jr. Melnikov)
      
       - Fix error handling for the ahci_ceva driver. Ensure that the
         ahci_ceva driver does a proper cleanup of its resources in the error
         path (Radhey Shyam Pandey)

      drm/amd/display: fix input states translation error for dcn35 & dcn351 · 27a6c493
      Swapnil Patel authored
      
      
      [Why]
      Currently there is an error while translating input clock sates into
      output clock states. The highest fclk setting from output sates is
      being dropped because of this error.
      
      [How]
      For dcn35 and dcn351, make output_states equal to input states.

      drm/amd/display: Fix potential null pointer dereference in dc_dmub_srv · d2b48f34
      Srinivasan Shanmugam authored
      Fixes potential null pointer dereference warnings in the
      dc_dmub_srv_cmd_list_queue_execute() and dc_dmub_srv_is_hw_pwr_up()
      functions.
      
      In both functions, the 'dc_dmub_srv' variable was being dereferenced
      before it was checked for null. This could lead to a null pointer
      dereference if 'dc_dmub_srv' is null. The fix is to check if
      'dc_dmub_srv' is null before dereferencing it.
      
      Thus moving the null checks for 'dc_dmub_srv' to the beginning of the
      functions to ensure that 'dc_dmub_srv' is not null when it is
      dereferenced.
      
      Found by smatch & thus fixing the below:
      drivers/gpu/drm/amd/amdgpu/../display/dc/dc_dmub_srv.c:133 dc_dmub_srv_cmd_list_queue_execute() warn: variable dereferenced before check 'dc_dmub_srv' (see line 128)

      Linus Torvalds authored
      Pull tracing fix from Steven Rostedt:
      
       - While working on the ring buffer I noticed that the counter used for
         knowing where the end of the data is on a sub-buffer was not a full
         "int" but just 20 bits. It was masked out to 0xfffff.
      
         With the new code that allows the user to change the size of the
         sub-buffer, it is theoretically possible to ask for a size bigger
         than 2^20. If that happens, unexpected results may occur as there's
         no code checking if the counter overflowed the 20 bits of the write
         mask. There are other checks to make sure events fit in the
         sub-buffer, but if the sub-buffer itself is too big, that is not
         checked.
      
         Add a check in the resize of the sub-buffer to make sure that it
         never goes beyond the size of the counter that holds how much data is
         on it.

      drm/amd/display: Only allow dig mapping to pwrseq in new asic · 4e738260
      Lewis Huang authored
      
      
      [Why]
      The old asic only have 1 pwrseq hw.
      We don't need to map the diginst to pwrseq inst in old asic.
      
      [How]
      1. Only mapping dig to pwrseq for new asic.
      2. Move mapping function into dcn specific panel control component

      drm/amd/display: adjust few initialization order in dm · 22e1dc4b
      Wayne Lin authored
      
      
      [Why]
      Observe error message "Can't retrieve aconnector in hpd_rx_irq_offload_work"
      when boot up with a mst tbt4 dock connected. After analyzing, there are few
      parts needed to be adjusted:
      
      1. hpd_rx_offload_wq[].aconnector is not initialzed before the dmub outbox
      hpd_irq handler get registered which causes the error message.
      
      2. registeration of hpd and hpd_rx_irq event for usb4 dp tunneling is not
      aligned with legacy interface sequence
      
      [How]
      Put DMUB_NOTIFICATION_HPD and DMUB_NOTIFICATION_HPD_IRQ handler
      registration into register_hpd_handlers() to align other interfaces and
      get hpd_rx_offload_wq[].aconnector initialized earlier than that.
      
      Leave DMUB_NOTIFICATION_AUX_REPLY registered as it was since we need that
      while calling dc_link_detect(). USB4 connection status will be proactively
      detected by dc_link_detect_connection_type() in amdgpu_dm_initialize_drm_device()

      drm/syncobj: handle NULL fence in syncobj_eventfd_entry_func · 2aa6f5b0
      Erik Kurzinger authored
      During syncobj_eventfd_entry_func, dma_fence_chain_find_seqno may set
      the fence to NULL if the given seqno is signaled and a later seqno has
      already been submitted. In that case, the eventfd should be signaled
      immediately which currently does not happen.
      
      This is a similar issue to the one addressed by commit b19926d4
      
      
      ("drm/syncobj: Deal with signalled fences in drm_syncobj_find_fence.").
      
      As a fix, if the return value of dma_fence_chain_find_seqno indicates
      success but it sets the fence to NULL, we will assign a stub fence to
      ensure the following code still signals the eventfd.

      drm/syncobj: call drm_syncobj_fence_add_wait when WAIT_AVAILABLE flag is set · 3c43177f
      Erik Kurzinger authored
      When waiting for a syncobj timeline point whose fence has not yet been
      submitted with the WAIT_FOR_SUBMIT flag, a callback is registered using
      drm_syncobj_fence_add_wait and the thread is put to sleep until the
      timeout expires. If the fence is submitted before then,
      drm_syncobj_add_point will wake up the sleeping thread immediately which
      will proceed to wait for the fence to be signaled.
      
      However, if the WAIT_AVAILABLE flag is used instead,
      drm_syncobj_fence_add_wait won't get called, meaning the waiting thread
      will always sleep for the full timeout duration, even if the fence gets
      submitted earlier. If it turns out that the fence *has* been submitted
      by the time it eventually wakes up, it will still indicate to userspace
      that the wait completed successfully (it won't return -ETIME), but it
      will have taken much longer than it should have.
      
      To fix this, we must call drm_syncobj_fence_add_wait if *either* the
      WAIT_FOR_SUBMIT flag or the WAIT_AVAILABLE flag is set. The only
      difference being that with WAIT_FOR_SUBMIT we will also wait for the
      fence to be signaled after it has been submitted while with
      WAIT_AVAILABLE we will return immediately.

      l2tp: pass correct message length to ip6_append_data · 359e54a9
      Tom Parkin authored
      l2tp_ip6_sendmsg needs to avoid accounting for the transport header
      twice when splicing more data into an already partially-occupied skbuff.
      
      To manage this, we check whether the skbuff contains data using
      skb_queue_empty when deciding how much data to append using
      ip6_append_data.
      
      However, the code which performed the calculation was incorrect:
      
           ulen = len + skb_queue_empty(&sk->sk_write_queue) ? transhdrlen : 0;
      
      ...due to C operator precedence, this ends up setting ulen to
      transhdrlen for messages with a non-zero length, which results in
      corrupted packets on the wire.
      
      Add parentheses to correct the calculation in line with the original
      intent.

      Netfilter fixes for net
      
      The following patchset contains Netfilter fixes for net:
      
      1) If user requests to wake up a table and hook fails, restore the
         dormant flag from the error path, from Florian Westphal.
      
      2) Reset dst after transferring it to the flow object, otherwise dst
         gets released twice from the error path.
      
      3) Release dst in case the flowtable selects a direct xmit path, eg.
         transmission to bridge port. Otherwise, dst is memleaked.
      
      4) Register basechain and flowtable hooks at the end of the command.
         Error path releases these datastructure without waiting for the
         rcu grace period.
      
      5) Use kzalloc() to initialize struct nft_hook to fix a KMSAN report
         on access to hook type, also from Florian Westphal.

      net: phy: realtek: Fix rtl8211f_config_init() for RTL8211F(D)(I)-VD-CG PHY · 3489182b
      Siddharth Vadapalli authored
      Commit bb726b75 ("net: phy: realtek: add support for
      RTL8211F(D)(I)-VD-CG") extended support of the driver from the existing
      support for RTL8211F(D)(I)-CG PHY to the newer RTL8211F(D)(I)-VD-CG PHY.
      
      While that commit indicated that the RTL8211F_PHYCR2 register is not
      supported by the "VD-CG" PHY model and therefore updated the corresponding
      section in rtl8211f_config_init() to be invoked conditionally, the call to
      "genphy_soft_reset()" was left as-is, when it should have also been invoked
      conditionally. This is because the call to "genphy_soft_reset()" was first
      introduced by the commit 0a4355c2 ("net: phy: realtek: add dt property
      to disable CLKOUT clock") since the RTL8211F guide indicates that a PHY
      reset should be issued after setting bits in the PHYCR2 register.
      
      As the PHYCR2 register is not applicable to the "VD-CG" PHY model, fix the
      rtl8211f_config_init() function by invoking "genphy_soft_reset()"
      conditionally based on the presence of the "PHYCR2" register.

      shared between all the net devices of the switch. It was noticed that
      when having two process which each of them trying to inject frames on
      different ethernet ports, that the HW started to behave strange, by
      sending out more frames then expected. When doing fdma injection it is
      required to set the frame in the DCB and then make sure that the next
      pointer of the last DCB is invalid. But because there is no locks for
      this, then easily this pointer between the DCB can be broken and then it
      would create a loop of DCBs. And that means that the HW will
      continuously transmit these frames in a loop. Until the SW will break
      this loop.
      Therefore to fix this issue, add a spin lock for when accessing the
      registers for manual or fdma injection.

      net/sched: flower: Add lock protection when remove filter handle · 1fde0ca3

      As IDR can't protect itself from the concurrent modification, place
      idr_remove() under the protection of tp->lock.
