+ <p>The vacmViewTreeFamilyMask is defined as a bit string in the MIB
+ (OCTET STRING). Internally a bitlist (list of 1's and 0's,
+ see <seealso marker="snmp_agent_config_files#vacm">vacm config file</seealso>

+ However, the MIB implementation assumed the latter, effectively

+ <p>Since the mask is used in hot paths (e.g. access permission checks
+ for each SNMP operation, the bitlist representation of the mask has
+ benefits (e.g. faster processing). Reading/writing the view mask
+ objects is less time-critical. Therefore, to fix the issue, convert
+ between the bitlist (internal) representation and bitstring
+ (external) when the vacmViewTreeFamilyMask objects are accessed. </p>
+ <p>Also, the check of the vacm config file was invalid with
+ regard to the mask value. It was assumed to be a proper oid, which
+ is not strictly the case (see bitlist above). </p>
