This becomes problematic when\nthe referenced entry produces non-deterministic output, such as FIT\nencryption using random IVs or timestamps, since rebuilding the entry\nchanges the data.\n\nThis series ensures that referenced entries are built only once and that\npreload signing is performed after all data is collected. It also avoids\nunnecessary repacking or repeated signing operations by the preload.\n\nThe changes include:\n * generate preload header placeholders in ObtainContents() and sign\n data only once in ProcessContentsUpdate()\n * mark referenced entries as build_done in the collection etype to\n avoid rebuilding data\n * add a functional test for signing an encrypted FIT with a preload\n header\n\nChanges in v6:\n - set build_done only when required=True, so it happens during\n ProcessContents() rather than ObtainContents()\n\nPaul HENRYS (2):\n binman: Generate preload header and sign data only once\n tools: binman: Test signing an encrypted FIT with a preload header\n\nyan wang (1):\n binman: collection: Set build_done on referenced entries\n\n tools/binman/etype/collection.py | 9 ++-\n tools/binman/etype/pre_load.py | 9 +--\n tools/binman/etype/section.py | 5 +-\n tools/binman/ftest.py | 21 +++++++\n .../test/security/pre_load_fit_encrypted.dts | 63 +++++++++++++++++++\n 5 files changed, 97 insertions(+), 10 deletions(-)\n create mode 100644 tools/binman/test/security/pre_load_fit_encrypted.dts" }
