      libata: LITE-ON CX1-JB256-HP needs lower max_sectors · 1488a1e3
      Tejun Heo authored
      Since 34b48db6 ("block: remove artifical max_hw_sectors cap"),
      max_sectors is no longer limited to BLK_DEF_MAX_SECTORS and LITE-ON
      CX1-JB256-HP keeps timing out with higher max_sectors.  Revert it to
      the previous value.

      mmc: pxamci: fix potential oops · b3802db5
      Robert Jarzmik authored
      As reported by Dan in his report in [1], there is a potential NULL
      pointer derefence if these conditions are met :
       - there is no platform_data provided, ie. host->pdata = NULL
      
      Fix this by only using the platform data ro_invert when a gpio for
      read-only is provided by the platform data.
      
      This doesn't appear yet as every pxa board provides a platform_data, and
      calls pxa_set_mci_info() with a non NULL pointer.
      
      [1] [bug report] mmc: pxamci: fix card detect with slot-gpio API.
      The commit fd546ee6 ("mmc: pxamci: fix card detect with slot-gpio
      API") from Sep 26, 2015, leads to the following static checker warning:
      
      	drivers/mmc/host/pxamci.c:809 pxamci_probe()
      	warn: variable dereferenced before check 'host->pdata' (see line 798)

      mmc: block: fix packed command header endianness · f68381a7
      Taras Kondratiuk authored
      The code that fills packed command header assumes that CPU runs in
      little-endian mode. Hence the header is malformed in big-endian mode
      and causes MMC data transfer errors:

      KEYS: Fix for erroneous trust of incorrectly signed X.509 certs · acddc720
      Mat Martineau authored
      Arbitrary X.509 certificates without authority key identifiers (AKIs)
      can be added to "trusted" keyrings, including IMA or EVM certs loaded
      from the filesystem. Signature verification is currently bypassed for
      certs without AKIs.
      
      Trusted keys were recently refactored, and this bug is not present in
      4.6.
      
      restrict_link_by_signature should return -ENOKEY (no matching parent
      certificate found) if the certificate being evaluated has no AKIs,
      instead of bypassing signature checks and returning 0 (new certificate
      accepted).
