Patch\n4/4, which add libcrypto support, has been modified to not use APIs that\nare deprecated in OpenSSL 3.0, to support Fedora 36.\n\nThe dependency on crypto libraries was optional, before we realized that\nmissing IPA protocol serialization made it effectively required in\npractice. Serialization is now there, so module signature support can be\nmade optional again. This could possibly cause issues for some users who\nmay not notice the missing dependency and wonder why IPA modules run\nisolated (although that should be a fully supported configuration).\n\nTo address this, I've documented module signing as recommended in\nREADME.md (patch 4/4), and emit a warning at meson setup time when the\ndependencies are not found. We however all know how often both\ndocumentation and warnings are overlooked. If anyone thinks this is a\nbad idea, I can drop (or modify) patch 4/4.\n\nFor the rest of the series, please see individual patches.\n\nEric, would you be able to test this on Fedora 36 to check if it fixes\nthe compilation issues you've reported ?\n\nLaurent Pinchart (4):\n libcamera: meson: Use dependency() to find gnutls\n libcamera: pub_key: Gracefully handle failures to load public key\n libcamera: pub_key: Support openssl as an alternative to gnutls\n libcamera: Make IPA module signing recommended instead of mandatory\n\n README.rst | 7 ++--\n include/libcamera/internal/pub_key.h | 8 +++--\n src/libcamera/ipa_manager.cpp | 3 ++\n src/libcamera/meson.build | 16 +++++++--\n src/libcamera/pub_key.cpp | 50 +++++++++++++++++++++++++---\n src/meson.build | 3 +-\n 6 files changed, 75 insertions(+), 12 deletions(-)\n\n\nbase-commit: fe8941d7d61bd22ed66e5b5615e931c68fdf9bfa" }
