* futility: Make --debug a global optionBill Richardson2015-03-111-12/+12
| | | | | | | | | | | | | | | Some commands look for a --debug option, others don't. The feature is implemented globally, so let's parse it as a global option.

* futility: Don't copy the entire kernel partition just to sign a blobBill Richardson2014-12-041-0/+23
| | | | | | | | | | | | | | | | | | When re-signing a kernel partition and writing the result into a new file, make sure we only emit the vblock and kernel blob instead of creating a new file that's the size of the entire partition. Also add a test for that.

* futility: return the correct size of kernel blob within partitionBill Richardson2014-12-041-41/+158
| | | | | | | | | | | | | | | | | When modifying a kernel partition in-place, make sure we only sign enough bytes to cover the kernel blob, not the entire partition. Also added a test for that case.

* futility: rolled back vbutil_kernel changeBill Richardson2014-10-021-70/+33
| | | | | | | | | | | | | | | | | | | | | When disabling verity with make_dev_ssh.sh, a bug in vbutil_kernel caused the re-signed kernel size to be the entire kernel partition instead of just the necessary bits. Until we can improve the test coverage, I'm rolling back the changes that introduced this bug. BUG=chromium:418647 BRANCH=ToT TEST=manual Created a new test image with these changes. You can install it and disable dm-verity and it works (although there seems to be an unrelated browser startup issue on ToT).

* futility: show vs verifyBill Richardson2014-09-271-0/+15
| | | | | | | | | | | | | | | | This adds a --strict mode to the show command, which requires that all signatures be valid in order to exit cleanly. It also creates a "verify" command, which is really just an alias for "show --strict".

* futility: implement vbutil_kernel using buffers, not filesBill Richardson2014-09-251-0/+168
The original vbutil_kernel command used file read and write to make changes. Futility prefers to use memory-mapped files. This rewrites cmd_vbutil_kernel.c to use that scheme. BUG=none BRANCH=ToT TEST=make runtests The original cmd_vbutil_kernel.c is renamed, and a test written to ensure that the refactored version produces identical results.
