[PATCH 0/3] ima: only call integrity_kernel_read to calc file hash

[Mimi Zohar]

The integrity_kernel_read() function was originally introduced to
read a file and calculate the file hash by-passing any security
checks.  Support subsequently was added allowing the kernel to read
a file containing a signed x509 certificate and load it onto either
the IMA or EVM keyring.

This patch set replaces the call to integrity_kernel_read() with the
common kernel_read_file_from_path() function, for reading and
loading an x509 certificate onto either the IMA or EVM keyring.  The
remaining calls to integrity_kernel_read() calculate a file hash, by
calling the new integrity_read file operation method.
