      Pull SCSI fixes from James Bottomley:
       "This is quite a big update because it includes a rework of the lpfc
        driver to separate the NVMe part from the FC part.
      
        The reason for doing this is because two separate trees (the nvme and
        scsi trees respectively) want to update the individual components and
        this separation will prevent a really nasty cross tree entanglement by
        the time we reach the next merge window.
      
        The rest of the fixes are the usual minor sort with no significant
        security implications"

      ptrace: Properly initialize ptracer_cred on fork · c70d9d80
      Eric W. Biederman 提交于
      When I introduced ptracer_cred I failed to consider the weirdness of
      fork where the task_struct copies the old value by default.  This
      winds up leaving ptracer_cred set even when a process forks and
      the child process does not wind up being ptraced.
      
      Because ptracer_cred is not set on non-ptraced processes whose
      parents were ptraced this has broken the ability of the enlightenment
      window manager to start setuid children.
      
      Fix this by properly initializing ptracer_cred in ptrace_init_task
      
      This must be done with a little bit of care to preserve the current value
      of ptracer_cred when ptrace carries through fork.  Re-reading the
      ptracer_cred from the ptracing process at this point is inconsistent
      with how PT_PTRACE_CAP has been maintained all of these years.

      efi-pstore: Fix write/erase id tracking · c10e8031
      Kees Cook 提交于
      Prior to the pstore interface refactoring, the "id" generated during
      a backend pstore_write() was only retained by the internal pstore
      inode tracking list. Additionally the "part" was ignored, so EFI
      would encode this in the id. This corrects the misunderstandings
      and correctly sets "id" during pstore_write(), and uses "part"
      directly during pstore_erase().

      In commit dc9c4d0f, the arp_target array moved from a static global
      to a local variable. By the nature of static globals, the array used to
      be initialized to all 0. At present, it's full of random data, which
      that gets interpreted as arp_target values, when none have actually been

      None of these were actually specified as ARP targets, and the driver does
      seem to clean up the mess okay, but it's rather noisy and confusing, leaks
      values to userspace, and the 255.255.255.255 spew shows up even when debug
      prints are disabled.
      
      The fix: just zero out arp_target at init time.
      
      While we're in here, init arp_all_targets_value in the right place.

      If ACMD12 in SDHCI is disabled, spurious tx done interrupts are seen
      on multi block read command with below error message:
      
      Got data interrupt 0x00000002 even though no data
      operation was in progress.
      
      This patch uses SDHCI_QUIRK_MULTIBLOCK_READ_ACMD12 to enable
      ACM12 support in SDHCI hardware and suppress spurious interrupt.

      bonding: fix accounting of active ports in 3ad · 751da2a6
      Jarod Wilson 提交于
      As of 7bb11dc9 and 0622cab0, bond slaves in a 3ad bond are not
      removed from the aggregator when they are down, and the active slave count
      is NOT equal to number of ports in the aggregator, but rather the number
      of ports in the aggregator that are still enabled. The sysfs spew for
      bonding_show_ad_num_ports() has a comment that says "Show number of active
      802.3ad ports.", but it's currently showing total number of ports, both
      active and inactive. Remedy it by using the same logic introduced in
      0622cab0 in __bond_3ad_get_active_agg_info(), so sysfs, procfs and
      netlink all report the number of active ports. Note that this means that
      IFLA_BOND_AD_INFO_NUM_PORTS really means NUM_ACTIVE_PORTS instead of
      NUM_PORTS, and thus perhaps should be renamed for clarity.
      
      Lightly tested on a dual i40e lacp bond, simulating link downs with an ip
      link set dev <slave2> down, was able to produce the state where I could
      see both in the same aggregator, but a number of ports count of 1.

      net: atheros: atl2: don't return zero on failure path in atl2_probe() · bd703a15
      Alexey Khoroshilov 提交于
      If dma mask checks fail in atl2_probe(), it breaks off initialization,
      deallocates all resources, but returns zero.
      
      The patch adds proper error code return value and
      make error code setup unified.

      mmc: cavium: Fix probing race with regulator · 8fb83b14
      Jan Glauber 提交于
      If the regulator probing is not yet finished this driver
      might catch a -EPROBE_DEFER. Returning after this condition
      did not remove the created platform device. On a repeated
      call to the probe function the of_platform_device_create
      fails.
      
      Calling of_platform_device_destroy after EPROBE_DEFER resolves
      this bug.

      of/platform: Make of_platform_device_destroy globally visible · c2372c20
      Jan Glauber 提交于
      of_platform_device_destroy is the counterpart to
      of_platform_device_create which is a non-static function.
      
      After creating a platform device it might be neccessary
      to destroy it to deal with -EPROBE_DEFER where a
      repeated of_platform_device_create call would fail otherwise.
      
      Therefore also make of_platform_device_destroy globally visible.

      Jan Glauber 提交于
      In case the DT specifies neither a regulator nor a gpio
      for the shared power the driver will crash accessing the regulator.
      Prevent the crash by checking the regulator before use.
      
      Use mmc_regulator_get_supply() instead of open coding the same
      logic.
