[PATCH v4 0/4] Add whitelisting support for load_env


From: Jon McCune
Subject: [PATCH v4 0/4] Add whitelisting support for load_env
Date: Tue, 24 Sep 2013 19:00:28 -0700

These patches add support to load_env and save_env to work nicely
in concert with check_signatures=enforce.  This represents an
evolution from the design in my email to grub-devel entitled
"Proposal to enable savedefault, one-shot reboot, etc with
check_signatures=enforce".  In particular, no new commands are added.
Instead, the behavior of load_env is modified based on the presence
of a whitelist of environment variables to be updated from an
untrusted grubenv-style file.

Some additional work is done to make this support usable:
A {-k, --pubkey} option is added to:
grub-install, grub-mkrescue, grub-mkstandalone, grub-mknetdir.
See the individual patch descriptions for more specifics.

Jon McCune (4):
  style: indent --no-tabs --gnu-style grub-core/commands/loadenv.c
  load_env support for whitelisting which variables are read from an env
    file, even if check_signatures=enforce
  save_env should work, even if check_signatures=enforce
  Add (multiple) -k, --pubkey=FILE support to installation commands.
