f9510887 - libsecureboot: allow OpenPGP support to be dormant

Wed, 26 Jun 2019 23:33:32 +0000

libsecureboot: allow OpenPGP support to be dormantSince we can now add OpenPGP trust anchors at runtime,ensure the latent support is available.Ensure we do not add duplicate keys to trust store.Also allow reporting names of trust anchors added/revokedWe only do this for loader and only after initializing trust store.Thus only changes to initial trust store will be logged.Reviewed by: stevekMFC after: 1 weekDifferential Revision: https://reviews.freebsd.org/D20700 List of files: /freebsd-13.1/lib/libsecureboot/libsecureboot-priv.h

b0fefb25 - Create kernel module to parse Veriexec manifest based on envs

Wed, 03 Apr 2019 03:57:37 +0000

Create kernel module to parse Veriexec manifest based on envsThe current approach of injecting manifest into mac_veriexec is toverify the integrity of it in userspace (veriexec (8)) and pass itsentries into kernel using a char device (/dev/veriexec).This requires verifying root partition integrity in loader,for example by using memory disk and checking its hash.Otherwise if rootfs is compromised an attacker could inject their own data.This patch introduces an option to parse manifest in kernel based on envs.The loader sets manifest path and digest.EVENTHANDLER is used to launch the module right after the rootfs is mounted.It has to be done this way, since one might want to verify integrity of the init file.This means that manifest is required to be present on the root partition.Note that the envs have to be set right before boot to make sure that no one can spoof them.Submitted by: Kornel Duleba Reviewed by: sjgObtained from: SemihalfSponsored by: StormshieldDifferential Revision: https://reviews.freebsd.org/D19281 List of files: /freebsd-13.1/lib/libsecureboot/libsecureboot-priv.h

13ea0450 - Extend libsecureboot(old libve) to obtain trusted certificates from UEFI and implement revocation

Wed, 06 Mar 2019 06:39:42 +0000

Extend libsecureboot(old libve) to obtain trusted certificates from UEFI and implement revocationUEFI related headers were copied from edk2.A new build option "MK_LOADER_EFI_SECUREBOOT" was added to allowloading of trusted anchors from UEFI.Certificate revocation support is also introduced.The forbidden certificates are loaded from dbx variable.Verification fails in two cases:There is a direct match between cert in dbx and the one in the chain.The CA used to sign the chain is found in dbx.One can also insert a hash of TBS section of a certificate into dbx.In this case verifications fails only if a direct match with acertificate in chain is found.Submitted by: Kornel Duleba Reviewed by: sjgObtained from: SemihalfSponsored by: StormshieldDifferential Revision: https://reviews.freebsd.org/D19093 List of files: /freebsd-13.1/lib/libsecureboot/libsecureboot-priv.h
