Re: [PATCH] IMA: Handle early boot data measurement

quoted

quoted

Please limit the changes in this patch to renaming the functions and/or
files.  For example, adding "measure_payload_hash" should be a separate
patch, not hidden here.

Thanks for the feedback Mimi.

I'll split this into 2 patches:

PATCH 1: Rename files + rename CONFIG
PATCH 2: Update IMA hook to utilize early boot data measurement.

I'm referring to introducing the "measure_payload_hash" flag.  I assume
this is to indicate whether the buffer should be hashed or not.

Example 1: ima_alloc_key_entry() and ima_alloc_data_entry(0 comparison

-static struct ima_key_entry *ima_alloc_key_entry(struct key *keyring,
-                                                const void *payload,
-                                                size_t payload_len)
-{

But in general, as much as possible function and file name changes
should be done independently of other changes.

thanks,
