Linux kernel stable tree
6fce1f40e9
Add a new configuration CONFIG_DM_VERITY_VERIFY_ROOTHASH_SIG_PLATFORM_KEYRING that enables verifying dm-verity signatures using the platform keyring, which is populated using the UEFI DB certificates. This is useful for self-enrolled systems that do not use MOK, as the secondary keyring which is already used for verification, if the relevant kconfig is enabled, is linked to the machine keyring, which gets its certificates loaded from MOK. On datacenter/virtual/cloud deployments it is more common to deploy one's own certificate chain directly in DB on first boot in unattended mode, rather than relying on MOK, as the latter typically requires interactive authentication to enroll, and is more suited for personal machines. Default to the same value as DM_VERITY_VERIFY_ROOTHASH_SIG_SECONDARY_KEYRING if not otherwise specified, as it is likely that if one wants to use MOK certificates to verify dm-verity volumes, DB certificates are going to be used too. Keys in DB are allowed to load a full kernel already anyway, so they are already highly privileged.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
