ima,evm: Add two variables to write filenames and signatures into

2023-11-08T12:09:28+00:00

Add two variables IMA_FILE_SIGNATURES_FILE and EVM_FILE_SIGNATURES_FILE for filenames where the ima_evm_sign_rootfs script can write the names of files and their IMA or EVM signatures into. Both variables are optional. The content of the file with IMA signatures may look like this: /usr/bin/gpiodetect ima:0x0302046730eefd... /usr/bin/pwscore ima:0x0302046730eefd004... Having the filenames along with their signatures is useful for signing files in the initrd when the initrd is running out of a tmpfs filesystem that has support for xattrs. This allows to enable an IMA appraisal policy already in the initrd where files must be signed as soon as the policy becomes active. Signed-off-by: Stefan Berger Signed-off-by: Armin Kuster

ima: Rename IMA_EVM_POLICY_SYSTEMD to IMA_EVM_POLICY

2023-05-06T11:54:09+00:00

The IMA policy will be specified using the IMA_EVM_POLICY variable since systemd will not be involved in loading the policy but the init script will load it. Signed-off-by: Stefan Berger Signed-off-by: Armin Kuster

meta-integrity: kernel-modsign: prevents splitting out debug symbols

2022-07-05T23:26:50+00:00

Starting with [1] kernel modules symbols is being slipped in OE-core and this breaks the kernel modules sign, so disable it. [1] https://git.openembedded.org/openembedded-core/commit/?id=e09a8fa931fe617afc05bd5e00dca5dd3fe386e8 Signed-off-by: Jose Quaresma Signed-off-by: Armin Kuster
