The prior commits create the separate hash so now it is time to update the initramfs framework so that veritysetup, which is responsible for binding the data and hash, is aware of when separate hash is in use, and can react accordingly. The added code follows the existing appended hash code style, but is considerably smaller because it doesn't have the large case statement that supports all possible identification schemes (label, UUID, ...). With the root hash split in two to create the respective partition UUIDs, we know exactly how to identify it, and the UUIDs used.

Meta-security
=============
The bbappend files for some recipes (e.g. linux-yocto) in this layer need
to have 'security' in DISTRO_FEATURES to have effect.
To enable them, add in configuration file the following line.
DISTRO_FEATURES:append = " security"
If meta-security is included, but security is not enabled as a
distro feature a warning is printed at parse time:
You have included the meta-security layer, but
'security' has not been enabled in your DISTRO_FEATURES. Some bbappend files
and preferred version setting may not take effect.
If you know what you are doing, this warning can be disabled by setting the following
variable in your configuration:
SKIP_META_SECURITY_SANITY_CHECK = 1
This layer provides security tools, hardening tools for Linux kernels
and libraries for implementing security mechanisms.
Dependencies
============
This layer depends on:
URI: git://git.openembedded.org/openembedded-core
branch: [same one as checked out for this layer]
URI: git://git.openembedded.org/meta-openembedded/meta-oe
branch: [same one as checked out for this layer]
Adding the security layer to your build
========================================
In order to use this layer, you need to make the build system aware of
it.
Assuming the security layer exists at the top-level of your
yocto build tree, you can add it to the build system by adding the
location of the security layer to bblayers.conf, along with any
other layers needed. e.g.:
BBLAYERS ?= " \
/path/to/oe-core/meta \
/path/to/meta-openembedded/meta-oe \
/path/to/layer/meta-security "
Optional Dynamic layer dependancy
======================================
URI: git://git.openembedded.org/meta-openembedded/meta-oe
URI: git://git.openembedded.org/meta-openembedded/meta-perl
URI: git://git.openembedded.org/meta-openembedded/meta-python
BBLAYERS += "/path/to/layer/meta-openembedded/meta-oe"
BBLAYERS += "/path/to/layer/meta-openembedded/meta-perl"
BBLAYERS += "/path/to/layer/meta-openembedded/meta-python"
This will activate the dynamic-layer mechanism.
Maintenance
======================================
Send pull requests, patches, comments or questions to yocto@lists.yoctoproject.org
When sending single patches, please using something like:
'git send-email -1 --to yocto@lists.yoctoproject.org --subject-prefix=meta-security][PATCH'
These values can be set as defaults for this repository:
$ git config sendemail.to yocto@lists.yoctoproject.org
$ git config format.subjectPrefix meta-security][PATCH
Now you can just do 'git send-email origin/master' to send all local patches.
For pull requests, please use create-pull-request and send-pull-request.
