      ocfs2: fix crash when initialize filecheck kobj fails · 7b0b1332
      Joseph Qi authored
      Once s_root is set, genric_shutdown_super() will be called if
      fill_super() fails.  That means, we will call ocfs2_dismount_volume()
      twice in such case, which can lead to kernel crash.
      
      Fix this issue by initializing filecheck kobj before setting s_root.

      configs/debug: restore DEBUG_INFO=y for overriding · 8208257d
      Qian Cai authored
      Previously, I failed to realize that Kees' patch [1] has not been merged
      into the mainline yet, and dropped DEBUG_INFO=y too eagerly from the
      mainline.  As the results, "make debug.config" won't be able to flip
      DEBUG_INFO=n from the existing .config.  This should close the gaps of a
      few weeks before Kees' patch is there, and work regardless of their
      merging status anyway.

      mm: swap: get rid of livelock in swapin readahead · 029c4628
      Guo Ziliang authored
      In our testing, a livelock task was found.  Through sysrq printing, same
      stack was found every time, as follows:
      
        __swap_duplicate+0x58/0x1a0
        swapcache_prepare+0x24/0x30
        __read_swap_cache_async+0xac/0x220
        read_swap_cache_async+0x58/0xa0
        swapin_readahead+0x24c/0x628
        do_swap_page+0x374/0x8a0
        __handle_mm_fault+0x598/0xd60
        handle_mm_fault+0x114/0x200
        do_page_fault+0x148/0x4d0
        do_translation_fault+0xb0/0xd4
        do_mem_abort+0x50/0xb0
      
      The reason for the livelock is that swapcache_prepare() always returns
      EEXIST, indicating that SWAP_HAS_CACHE has not been cleared, so that it
      cannot jump out of the loop.  We suspect that the task that clears the
      SWAP_HAS_CACHE flag never gets a chance to run.  We try to lower the
      priority of the task stuck in a livelock so that the task that clears
      the SWAP_HAS_CACHE flag will run.  The results show that the system
      returns to normal after the priority is lowered.
      
      In our testing, multiple real-time tasks are bound to the same core, and
      the task in the livelock is the highest priority task of the core, so
      the livelocked task cannot be preempted.
      
      Although cond_resched() is used by __read_swap_cache_async, it is an
      empty function in the preemptive system and cannot achieve the purpose
      of releasing the CPU.  A high-priority task cannot release the CPU
      unless preempted by a higher-priority task.  But when this task is
      already the highest priority task on this core, other tasks will not be
      able to be scheduled.  So we think we should replace cond_resched() with
      schedule_timeout_uninterruptible(1), schedule_timeout_interruptible will
      call set_current_state first to set the task state, so the task will be
      removed from the running queue, so as to achieve the purpose of giving
      up the CPU and prevent it from running in kernel mode for too long.
      
      (akpm: ugly hack becomes uglier.  But it fixes the issue in a
      backportable-to-stable fashion while we hopefully work on something
      better)

      iavf: Fix hang during reboot/shutdown · b04683ff
      Ivan Vecera authored
      Recent commit 97457801 ("iavf: Add waiting so the port is
      initialized in remove") adds a wait-loop at the beginning of
      iavf_remove() to ensure that port initialization is finished
      prior unregistering net device. This causes a regression
      in reboot/shutdown scenario because in this case callback
      iavf_shutdown() is called and this callback detaches the device,
      makes it down if it is running and sets its state to __IAVF_REMOVE.
      Later shutdown callback of associated PF driver (e.g. ice_shutdown)
      is called. That callback calls among other things sriov_disable()
      that calls indirectly iavf_remove() (see stack trace below).
      As the adapter state is already __IAVF_REMOVE then the mentioned
      loop is end-less and shutdown process hangs.
      
      The patch fixes this by checking adapter's state at the beginning
      of iavf_remove() and skips the rest of the function if the adapter
      is already in remove state (shutdown is in progress).
      
      Reproducer:
      1. Create VF on PF driven by ice or i40e driver
      2. Ensure that the VF is bound to iavf driver
      3. Reboot

      net: mscc: ocelot: fix backwards compatibility with single-chain tc-flower offload · 8e0341ae
      Vladimir Oltean authored
      ACL rules can be offloaded to VCAP IS2 either through chain 0, or, since
      the blamed commit, through a chain index whose number encodes a specific
      PAG (Policy Action Group) and lookup number.
      
      The chain number is translated through ocelot_chain_to_pag() into a PAG,
      and through ocelot_chain_to_lookup() into a lookup number.
      
      The problem with the blamed commit is that the above 2 functions don't
      have special treatment for chain 0. So ocelot_chain_to_pag(0) returns
      filter->pag = 224, which is in fact -32, but the "pag" field is an u8.
      
      So we end up programming the hardware with VCAP IS2 entries having a PAG
      of 224. But the way in which the PAG works is that it defines a subset
      of VCAP IS2 filters which should match on a packet. The default PAG is
      0, and previous VCAP IS1 rules (which we offload using 'goto') can
      modify it. So basically, we are installing filters with a PAG on which
      no packet will ever match. This is the hardware equivalent of adding
      filters to a chain which has no 'goto' to it.
      
      Restore the previous functionality by making ACL filters offloaded to
      chain 0 go to PAG 0 and lookup number 0. The choice of PAG is clearly
      correct, but the choice of lookup number isn't "as before" (which was to
      leave the lookup a "don't care"). However, lookup 0 should be fine,
      since even though there are ACL actions (policers) which have a
      requirement to be used in a specific lookup, that lookup is 0.
      
      Fixes: 226e9cd8 ("net: mscc: ocelot: only install TCAM entries into a specific lookup and PAG")

      bnx2x: fix built-in kernel driver load failure · 424e7834
      Manish Chopra authored
      Commit b7a49f73 ("bnx2x: Utilize firmware 7.13.21.0")
      added request_firmware() logic in probe() which caused
      load failure when firmware file is not present in initrd (below),
      as access to firmware file is not feasible during probe.
      
        Direct firmware load for bnx2x/bnx2x-e2-7.13.15.0.fw failed with error -2
        Direct firmware load for bnx2x/bnx2x-e2-7.13.21.0.fw failed with error -2
      
      This patch fixes this issue by -
      
      1. Removing request_firmware() logic from the probe()
         such that .ndo_open() handle it as it used to handle
         it earlier
      
      2. Given request_firmware() is removed from probe(), so
         driver has to relax FW version comparisons a bit against
         the already loaded FW version (by some other PFs of same
         adapter) to allow different compatible/close enough FWs with which
         multiple PFs may run with (in different environments), as the
         given PF who is in probe flow has no idea now with which firmware
         file version it is going to initialize the device in ndo_open()

      net: dsa: Add missing of_node_put() in dsa_port_parse_of · cb0b430b
      Miaoqian Lin authored
      The device_node pointer is returned by of_parse_phandle()  with refcount
      incremented. We should use of_node_put() on it when done.

      drm: Don't make DRM_PANEL_BRIDGE dependent on DRM_KMS_HELPERS · 3c338405
      Thomas Zimmermann authored
      Fix a number of undefined references to drm_kms_helper.ko in
      drm_dp_helper.ko:
      
        arm-suse-linux-gnueabi-ld: drivers/gpu/drm/dp/drm_dp_mst_topology.o: in function `drm_dp_mst_duplicate_state':
        drm_dp_mst_topology.c:(.text+0x2df0): undefined reference to `__drm_atomic_helper_private_obj_duplicate_state'
        arm-suse-linux-gnueabi-ld: drivers/gpu/drm/dp/drm_dp_mst_topology.o: in function `drm_dp_delayed_destroy_work':
        drm_dp_mst_topology.c:(.text+0x370c): undefined reference to `drm_kms_helper_hotplug_event'
        arm-suse-linux-gnueabi-ld: drivers/gpu/drm/dp/drm_dp_mst_topology.o: in function `drm_dp_mst_up_req_work':
        drm_dp_mst_topology.c:(.text+0x7938): undefined reference to `drm_kms_helper_hotplug_event'
        arm-suse-linux-gnueabi-ld: drivers/gpu/drm/dp/drm_dp_mst_topology.o: in function `drm_dp_mst_link_probe_work':
        drm_dp_mst_topology.c:(.text+0x82e0): undefined reference to `drm_kms_helper_hotplug_event'
      
      This happens if panel-edp.ko has been configured with
      
        DRM_PANEL_EDP=y
        DRM_DP_HELPER=y
        DRM_KMS_HELPER=m
      
      which builds DP helpers into the kernel and KMS helpers sa a module.
      Making DRM_PANEL_EDP select DRM_KMS_HELPER resolves this problem.
      
      To avoid a resulting cyclic dependency with DRM_PANEL_BRIDGE, don't
      make the latter depend on DRM_KMS_HELPER and fix the one DRM bridge
      drivers that doesn't already select DRM_KMS_HELPER. As KMS helpers
      cannot be selected directly by the user, config symbols should avoid
      depending on it anyway.

      smb3: fix incorrect session setup check for multiuser mounts · e3ee9fb2
      Steve French authored
      A recent change to how the SMB3 server (socket) and session status
      is managed regressed multiuser mounts by changing the check
      for whether session setup is needed to the socket (TCP_Server_info)
      structure instead of the session struct (cifs_ses). Add additional
      check in cifs_setup_sesion to fix this.
