[ptxdist] [PATCH v2 00/15] Fix/extend code signing infrastructure/consumers

[ptxdist] [PATCH v2 00/15] Fix/extend code signing infrastructure/consumers

[Bastian Krause]

This series includes various bug fixes and extensions of ptxdist's code
signing infrastructure and its consumers. This includes HAB barebox
images, signed FIT images and RAUC bundles. Real HSMs can now be used
for signing. Newly introduced helpers simplify CA handling.

Changes since implicit v1 (20200514134300.16105-1-bst@pengutronix.de and
following, without cover letter):
  - add new line when appending to a CA
  - select necessary host tools directly in code signing provier, not in
    CODE_SIGNING
  - add code signing env to image rauc env
  - re-add accidentally dropped rules/code-signing.in introducing
    CODE_SIGNING for ptxconfig
  - move "code-signing: introduce for ptxconfig, add sanity check"
    before "rauc/image-rauc: use code signing infrastructure for key
    retrieval"
  - clarify required versions of genimage/ptx-code-signing-dev in commit
    messages
  - add rauc version bump
  - sign ramdisk in FIT images (if enabled)

Regards,
Bastian

[ptxdist] [PATCH v2 03/15] ptxd_lib_imx_hab: fix srk fuse file and table generation

[Bastian Krause]

srktool's help text states "certificate filenames must be separated by
a ',' with no spaces". Line continuating using "\" with the next line
being indented leads to a space being inserted between the SRK2
certificate and the SRK3 certificate.
srktool does not fail, but ignores everything after the space silently.
Thus only the first two certicates end up in the fuse file and table.

Fix this by specifying all certs on a single line.

[ptxdist] [PATCH v2 04/15] ptxd_lib_code_signing: introduce CA helper

[Bastian Krause]

These helpers allow key providers to append certificates to their CA.
'cs_get_ca <role>' then returns the path to the keyring allowing rules
and other helpers to retrieve it easily.

[ptxdist] [PATCH v2 05/15] host-ptx-code-signing-dev: version bump 0.2 -> 0.4

[Bastian Krause]

This includes a fix of a copy/paste error in import_rauc_keys's role.
Additionally the new helper cs_append_ca_from_uri is now used for RAUC
and HAB SRK roles. The helper function requires HOST_EXTRACT_CERT,
HOST_OPENSSL and HOST_LIBP11.

Signed-off-by: Bastian Krause <bst@pengutronix.de>
---
Changes since (implicit) v1:
  - select necessary host tools directly in code signing provier, not in
    CODE_SIGNING
  - select required HOST_LIBP11

[ptxdist] [PATCH v2 06/15] ptxd_lib_imx_hab/template-barebox-imx-habv4: use cs_get_ca helper

[Bastian Krause]

Key providers now take care of calling the CA helpers. This makes sure
the CA is already present in pem format. Use that instead of extracting
and converting the certs here again. Thus HOST_EXTRACT_CERT is no longer
a dependency of template-barebox-imx-habv4.

Note: requires ptx-code-signing-dev 0.4 or later

Changes since (implicit) v1:
  - clarify required version of ptx-code-signing-dev in commit message

[ptxdist] [PATCH v2 09/15] u-boot/ptxd_make_fit_image: avoid overriding object name

[Bastian Krause]

Having multiple "object=" occurrences in a single PKCS#11 URI does not
work for all cases, at least not for opensc-pkcs11. Thus u-boot's
PKCS#11 handling was patched to avoid overriding the object name when
it is already specified. The patch was sent upstream.

[ptxdist] [PATCH v2 10/15] ptxd_make_fit_image: sign ramdisk if enabled

[Bastian Krause]

Until now only kernel and fdt are signed by mkimage. If a ramdisk is
used sign it also.

Unfortunately quotes are not usable in the alternative value of
variable paramater substitution ${parameter:+alt_value}:

  https://stackoverflow.com/questions/40995523/bash-variable-expansion-var-in-here-document-removing-double-quotes

Thus use printf as a workaround.

[ptxdist] [PATCH v2 13/15] rauc/image-rauc: use code signing infrastructure for key retrieval

[Bastian Krause]

Use the keys provided by the currently active key provider via PKCS#11
instead of key files placed in the platform config directory. In order
to make sure the new mechanics are used after a BSP update the rauc.key
file is no longer allowed to exist in the platformconfig directory.

Note: requires genimage v13 or later and ptx-code-signing-dev 0.4 or
later

Signed-off-by: Bastian Krause <bst@pengutronix.de>

  - add code signing env to image rauc env
  - clarify required versions of genimage/ptx-code-signing-dev in commit
