[Rpm-maint] [RFC PATCH v3 0/4] Include and install file signatures

[fin at linux.vnet.ibm.com]

From: Fionnuala Gunter <fin at linux.vnet.ibm.com>

The Linux kernel's ima-appraisal module verifies file signatures. The problem 
with verifying digital signatures of files is how the files are signed in the 
first place. In our current prototype, we sign all files after system 
installation, but this doesn't handle ongoing updates. We propose that Linux 
distributors sign all files as part of the normal package signing. RPM already 
maintains hashes of all files in the rpm package, and this can be extended to 
add file signatures.

This patch set extends the rpm signing tool to include file signatures in 
packages, and extends the rpm install tool to install file signatures.

Changelog v2: 
-support for inline signing of files
-command line option for file signing key
-included missing file
-fixed type in rpmDigestAlgo

Changelog v3:
-split up patch

Fionnuala Gunter (4):
  Add file signature to fsm_file_post parameter list
  Sign package files and include signatures in package header
  Label ima xattr when signed files are installed
  Sign package files during installation
