boot: Add fit_config_get_hash_list() to build signed node list 2026-03-09T15:49:50+00:00 Simon Glass simon.glass@canonical.com 2026-03-06T01:20:09+00:00 2092322b31cc8b1f8c9e2e238d1043ae0637b241 The hashed-nodes property in a FIT signature node lists which FDT paths are included in the signature hash. It is intended as a hint so should not be used for verification. Add a function to build the node list from scratch by iterating the configuration's image references. Skip properties known not to be image references. For each image, collect the path plus all hash and cipher subnodes. Use the new function in fit_config_check_sig() instead of reading 'hashed-nodes'. Update the test_vboot kernel@ test case: fit_check_sign now catches the attack at signature-verification time (the @-suffixed node is hashed instead of the real one, causing a mismatch) rather than at fit_check_format() time. Update the docs to cover this. The FIT spec can be updated separately.

The hashed-nodes property in a FIT signature node lists which FDT paths
are included in the signature hash. It is intended as a hint so should
not be used for verification.

Add a function to build the node list from scratch by iterating the
configuration's image references. Skip properties known not to be image
references. For each image, collect the path plus all hash and cipher
subnodes.

Use the new function in fit_config_check_sig() instead of reading
'hashed-nodes'.

Update the test_vboot kernel@ test case: fit_check_sign now catches the
attack at signature-verification time (the @-suffixed node is hashed
instead of the real one, causing a mismatch) rather than at
fit_check_format() time.

Update the docs to cover this. The FIT spec can be updated separately.

Since these properties are now available in the U-Boot device tree, it's now possible to use the same blob generated by U-Boot in place of the stub, when creating boot images. Update the build documentation to reflect the same. Signed-off-by: Kaustabh Chakraborty <kauschluss@disroot.org> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>
