| | | | | | | | | | | | | | | | During software installation, use veriexec -S to strictly enforce certificate validity checks (notBefore, notAfter). Otherwise ignore certificate validity period. It is generally unacceptible for the Internet to stop working just because someone did not upgrade their infrastructure for a decade. Sponsored by: Juniper Networks, Inc.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need a valid st_dev, st_ino and st_mtime to correctly track which files have been verified and to update our notion of time. ve_utc_set(): ignore utc if it would jump our current time by more than VE_UTC_MAX_JUMP (20 years). Allow testing of install command via userboot. Need to fix its stat implementation too. bhyveload also needs stat fixed - due to change to userboot.h Call ve_error_get() from vectx_close() when hash is wrong. Track the names of files we have hashed into pcr For the purposes of measured boot, it is important to be able to reproduce the hash reflected in loader.ve.pcr so loader.ve.hashed provides a list of names in the order they were added.

* veloader use vectx API for kernel and modulesSimon J. Gerraty2020-03-085-74/+197
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The vectx API, computes the hash for verifying a file as it is read. This avoids the overhead of reading files twice - once to verify, then again to load. For doing an install via loader, avoiding the need to rewind large files is critical. This API is only used for modules, kernel and mdimage as these are the biggest files read by the loader. The reduction in boot time depends on how expensive the I/O is on any given platform. On a fast VM we see 6% improvement. For install via loader the first file to be verified is likely to be the kernel, so some of the prep work (finding manifest etc) done by verify_file() needs to be factored so it can be reused for vectx_open(). For missing or unrecognized fingerprint entries, we fail in vectx_open() unless verifying is disabled. Otherwise fingerprint check happens in vectx_close() and since this API is only used for files which must be verified (VE_MUST) we panic if we get an incorrect hash.

* Create kernel module to parse Veriexec manifest based on envsMarcin Wojtas2019-04-035-4/+167
| | | | | | | | | | | | | | | | | | | | | | | | | The current approach of injecting manifest into mac_veriexec is to verify the integrity of it in userspace (veriexec (8)) and pass its entries 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.

A new build option "MK_LOADER_EFI_SECUREBOOT" was added to allow loading 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 a certificate in chain is found.
