[dm-devel] [PATCH 0/6] updates to device mapper target measurement using ima

[Tushar Sugandhi <tusharsu@linux.microsoft.com>]

There were several improvements suggested for the original device mapper
target measurement patch series [1].

Those improvement suggestions include: 
 - Prefixing hashes for the DM tables being measured in ima log with the
   hash algorithm.
 - Adding version information for DM related events being measured in the
   ima log.
 - Prefixing DM related event names with "dm_".
 - Including the verity target attribute - "root_hash_sig_key_desc"
   in the ima measurement log.

This series incorporates the above suggestions.

This series also has the following fixes:
 - Adding a one-time warning to dmesg during dm_init if
   CONFIG_IMA_DISABLE_HTABLE is set to 'n'.
 - Updating 'integrity' target to remove the duplicate measurement of
   the attribute "mode=%c".
 - Indexing various attributes in 'multipath' target, and adding
   "nr_priority_groups=%u" attribute to the measurements.
 - Fixing 'make htmldocs' warnings in dm-ima.rst.
 - Adding missing documentation for the targets - 'cache', 'integrity',
   'multipath', and 'snapshot' in dm-ima.rst.
 - Updating dm-ima.rst documentation with the grammar for various DM
   events and targets in Backus Naur form.
 - Updating dm-ima.rst documentation to be consistent with the code
   changes described above.

This series is based on top of the following git repo/branch/commit:
