This new patch series is a rebase on David Howells's keys-misc branch. This mainly fixes UEFI DBX and the new Eric Snowberg's feature to import asymmetric keys to the blacklist keyring. I successfully tested this patch series with the 186 entries from https://uefi.org/sites/default/files/resources/dbxupdate_x64.bin (184 binary hashes and 2 certificates). The goal of these patches is to add a new configuration option to enable the root user to load signed keys in the blacklist keyring. This keyring is useful to "untrust" certificates or files. Enabling to safely update this keyring without recompiling the kernel makes it more usable. This can be applied on top of David Howells's keys-next branch: https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git/log/?h=keys-next Git commits can be found in https://github.com/l0kod/linux branch dyn-auth-blacklist-v6 commit fcf976b74ffcd4551683e6b70dbf5fb102cf9906 .
