2020-08-04Add support for vendor_db built-in shim whitelistAlexander Burmashev
Potential new signing strategies ( for example signing grub, fwupdate and vmlinuz with separate certificates ) require shim to support a vendor provided bundle of trusted certificates and hashes, which allows shim to "whitelist" EFI binaries matching either certificate by signature, or hash in the vendor_db.. Functionality is similar to vendor_dbx ( vendor blacklist ). Patch is a polished version of code, authored by P. Jones. Signed-off-by: Alex Burmashev <alexander.burmashev@oracle.com>

2018-03-06Log measurements in PCR4 for applications being verified through shim_lockTamas K Lengyel
Currently the only measurement the shim logs in the TPM is that of the EFI application it directly loads. However, there are no measurements being taken of application that are being verified through the shim_lock protocol. In this patch we extend PCR4 for any binary for which Verify is being called through the shim_lock protocol. Signed-off-by: Tamas K Lengyel <lengyelt@ainfosec.com>
