(bsc#1198458) * Updated vendor dbx binary and script (bsc#1198458) * Updated dbx-cert.tar.xz and vendor-dbx-sles.bin for adding SLES-UEFI-SIGN- Certificate-2021-05.crt to vendor dbx list. * Updated dbx-cert.tar.xz and vendor-dbx-opensuse.bin for adding openSUSE- UEFI-SIGN-Certificate-2021-05.crt to vendor dbx list. * Updated vendor-dbx.bin for adding SLES-UEFI-SIGN-Certificate-2021-05.crt and openSUSE-UEFI-SIGN-Certificate-2021-05.crt for testing environment. * Updated generate-vendor-dbx.sh script for generating a vendor-dbx.bin file which includes all .der for testing environment. * avoid buffer overflow when copying data to the MOK config table (bsc#1185232) * Disable exporting vendor-dbx to MokListXRT since writing a large RT variable could crash some machines (bsc#1185261) * ignore the odd LoadOptions length (bsc#1185232) * shim-install: reset def_shim_efi to "shim.efi" if the given file doesn't exist * relax the maximum variable size check for u-boot (bsc#1185621) * handle ignore_db and user_insecure_mode correctly (bsc#1185441, bsc#1187071) * Split the keys in vendor-dbx.bin to vendor-dbx-sles and vendor-dbx-opensuse for shim-sles and shim-opensuse to reduce the size of MokListXRT (bsc#1185261) * Also update generate-vendor-dbx.sh in dbx-cert.tar.xz ## Patch Instructions: To install this SUSE update use the SUSE recommended installation methods like YaST online_update or "zypper patch".
