43800cdc6e Initial implementation of keyring
Keyring is an encrypted file to store secrets. The encryption key is
derived from the disk decryption passphrase so that the file can be
automatically decrypted and processed during boot.

The keys contained in the keyring file are loaded into the kernel key
store so that they can later be retrieved by other components.

Currenly during installation a signing key is generated and stored in
the keyring so that the system can transparently sign RealmFS images
when the user modifies or updates them.

2dc32d1f20 Refactor multiple tools into a single binary.
citadel-tool now installed with a hardlink for each binary tool and
dispatches on the exe path to the tool implementation. This makes
the build faster, uses less disk space, and makes it easier to
create new small tools.

0b2480f849 Refactor to chain realm specific config to global config
Now if a variable is not set in a realm config file (or the file does
not exist), the 'global' config file will also be searched in the
parent directory (ie: /storage/realms/config). If the variable is
still not found, the value from the default instance is returned.

6215b58167 realmfs-owner is name of realm that can write to unsealed realm 2019-01-30 14:06:18 -05:00
191b580440 refactor verity module to work on images without removing header first 2019-01-30 14:05:11 -05:00
e7e75061a1 Everything optional except 'image-type' now. Also removed a couple fields.
When a RealmFS image is not sealed it has a very simple header and
doesn't use most of the metainfo fields.

3782668514 Refactor how images are built to support realmfs images
Main change in building images is that an empty 4096 byte block is
prepended to raw image before compression so that upon decompression
the header can be written without having to shuffle around decompressed
image.

f5bf92f488 function for piping section of a file to a command
This makes it possible to calculate sha256sum in place on an image file
which has both a header and an appended dm-verity tree. Before this
required a message process of extracting the body into a temporary file.

4f603cf4d4 add two flags to install-rootfs, --just-choose and --skip-sha
--just-choose will print information about which partition would be
chosen to install a rootfs image.

--skip-sha will avoid checking the sha256 sum of the image file. This
is mainly meant for use by the installer since the sum has already
been confirmed
