[PATCH v17 00/20] Automatic Disk Unlock with TPM2 |

GIT repo for v17: https://github.com/lcp/grub2/tree/tpm2-unlock-v17
This patch series is based on "Automatic TPM Disk Unlock"(*1) posted by
Hernan Gatta to introduce the key protector framework and TPM2 stack
to GRUB2, and this could be a useful feature for the systems to
implement full disk encryption.
To support TPM 2.0 Key File format(*2), patch 1~4,6,7 are grabbed from
Daniel Axtens's "appended signature secure boot support" (*3) to import
libtasn1 into grub2. Besides, the libtasn1 version is upgraded to
4.19.0 instead of 4.16.0 in the original patch.
Patch 5 fixes a potential buffer overrun in libtasn1.
(https://gitlab.com/gnutls/libtasn1/-/issues/49)
Patch 8 adds the document for libtasn1 and the steps to upgrade the
library.
Patch 9~13 are Hernan Gatta's patches with the follow-up fixes and
improvements:
- Converting 8 spaces into 1 tab
- Merging the minor build fix from Michael Chang
- Replacing "lu" with "PRIuGRUB_SIZE" for grub_dprintf
- Adding "enable = efi" to the tpm2 module in grub-core/Makefile.core.def
- Rebasing "cryptodisk: Support key protectors" to the git master
- Removing the measurement on the sealed key
- Based on the patch from Olaf Kirch <OKir@suse.com>
- Adjusting the input parameters of TPM2_EvictControl to match the order
in "TCG TPM2 Part3 Commands"
- Declaring the input arguments of TPM2 functions as const
- Resending TPM2 commands on TPM_RC_RETRY
- Adding checks for the parameters of TPM2 commands
- Packing the missing authorization command for TPM2_PCR_Read
- Tweaking the TPM2 command functions to allow some parameters to be
NULL so that we don't have to declare empty variables
- Only enabling grub-protect for "efi" since the TPM2 stack currently
relies on the EFI TCG2 protocol to send TPM2 commands
- Using grub_cpu_to_be*() in the TPM2 stack instead of grub_swap_bytes*()
which may cause problems in big-indian machines
- Changing the short name of "--protector" of "cryptomount" from "-k" to
"-P" to avoid the conflict with "--key-file"
- Supporting TPM 2.0 Key File Format besides the raw sealed key
- Adding the external libtasn1 dependency to grub-protect to write the
TPM 2.0 Key files
- Extending the TPM2 TSS stack to support authorized policy
Patch 14 implements the authorized policy support.
Patch 15 implements the missing NV index mode. (Thanks to Patrick Colp)
Patch 16 improves the 'cryptomount' command to fall back to the
passphrase mode when the key protector fails to unlock the encrypted
partition. (Another patch from Patrick Colp)
Patch 17 and 18 fix the potential security issues spotted by Fabian Vogt.
Patch 19 and 20 implement the TPM key unsealing testcases.
To utilize the TPM2 key protector to unlock the encrypted partition
(sdb1), here are the sample steps:
1. Add an extra random key for LUKS (luks-key)
$ dd if=/dev/urandom of=luks-key bs=1 count=32
$ sudo cryptsetup luksAddKey /dev/sdb1 luks-key --pbkdf=pbkdf2
2. Seal the key
$ sudo grub-protect --action=add \
--protector=tpm2 \
--tpm2key \
--tpm2-keyfile=luks-key \
--tpm2-outfile=/boot/efi/boot/grub2/sealed.tpm
3. Unseal the key with the proper commands in grub.cfg:
tpm2_key_protector_init --tpm2key=(hd0,gpt1)/boot/grub2/sealed.tpm
cryptomount -u <SDB1_UUID> -P tpm2

(*3) https://lists.gnu.org/archive/html/grub-devel/2021-06/msg00044.html
v17:
- Fixing the missing space in strncat()
- Updating the steps to import libtasn1
- Moving libtasn1.h to grub-core/lib/libtasn1/ and fixing the affected
patches
- libtasn1.h is included in tpm2key.h, so there is no need to include
the header again in module.c and tpm2key.c.
- Applying the libtasn1 patches in a different way
- Instead of applying the patches directly in the grub2 source code,
libtasn1 is copied to grub-core/lib/libtasn1-grub by autogen.sh and
then the script applies the libtasn1 patches to libtasn1-grub.
- The patch files in patch 3, 4, and 5 are created by the following
repo against the libtasn1-4.19.0-base tag.
https://github.com/lcp/grub2/tree/import-libtasn1-4.19.0

triggered later

- Stopping reading SRK from the well-known persistent handle (TPM2_SRK_HANDLE,

-+libtasn1 is a library providing Abstract Syntax Notation One (ASN.1, as
-+specified by the X.680 ITU-T recommendation) parsing and structures
management,
-+and Distinguished Encoding Rules (DER, as per X.690) encoding and decoding
-+functions.
-+
-+To upgrade to a new version of the libtasn1 library, download the release
-+tarball and copy the files into the target directory:
-+
-+@example
-+curl -L -O https://ftp.gnu.org/gnu/libtasn1/libtasn1-4.19.0.tar.gz

-+@end example
-+
-+After upgrading the library, it may be necessary to apply the patches in
-+@file{grub-core/lib/libtasn1-patches/} to adjust the code to be
compatible with
-+grub. These patches were needed to use the current version of libtasn1.
The
-+existing patches may not apply cleanly, apply at all, or even be needed
for a
-+newer version of the library, and other patches maybe needed due to
changes in
-+the newer version. If existing patches need to be refreshed to apply
cleanly,
-+please include updated patches as part of the a patch set sent to the
list.
-+If new patches are needed or existing patches are not needed, also please
send
-+additions or removals as part of any patch set upgrading libtasn1.
-+

- @chapter Debugging
-
+ Do that with #if 0/#endif, rather than deletion. This means
+ that the difference between upstream and grub is smaller,
+ which should make updating libtasn1 easier in the future.
+
+ With these exclusions we also avoid the need for minmax.h,
+ which is convenient because it means we don't have to
+ import it from gnulib.

-+
-+Do a few things to make libtasn1 compile as part of grub:
-+
-+ - remove _asn1_strcat and replace strcat with the bound-checked
-+ _asn1_str_cat except the one inside _asn1_str_cat. That strcat is
-+ replaced with strcpy.
-+
-+ - adjust header paths in libtasn1.h
-+
-+ - adjust header paths to "grub/libtasn1.h".
-+
-+ - replace a 64 bit division with a call to grub_divmod64, preventing
-+ creation of __udivdi3 calls on 32 bit platforms.

-+Subject: [PATCH 3/3] libtasn1: fix the potential buffer overrun
-+
-+In _asn1_tag_der(), the first while loop for the long form may end up
-+with a 'k' value with 'ASN1_MAX_TAG_SIZE' and cause the buffer overrun
-+in the second while loop. This commit tweaks the conditional check to

This test script firstly creates a simple LUKS image to be loaded as a
loopback device in grub-emu. Then an emulated TPM device is created by
- swtpm_cuse and PCR 0 and 1 are extended.
+ "swtpm chardev" and PCR 0 and 1 are extended.
There are several test cases in the script to test various settings.
Each
test case uses grub-protect or tpm2-tools to seal the LUKS password
