From long description I see zero motivation to ack this change, except
some heresay about IMA requiring it. Why does IMA need update_cnt and
why this is not documented to the long description?
The motivation is to detect whether the IMA measurement list has been
truncated, for whatever reason. A new IMA record should be defined
containing the "pcrCounter" value. (I have not had a chance to review
this patch set.)
This new record would be a pre-req for both Tushar's "ima: measure
events between kexec load and execute" patch set and Sush's proposal to
trim the measurement list. (I haven't looked at it yet either.)
Thanks Mimi. Take your time.
