The first patch is new because it'a a cleanup that does not require any change to the module verification code. The second patch is the only one that is intended to change any functionality. The rest only deduplicates code but I did not receive any review on that part so I don't know if it's desirable as implemented. The first two patches can be applied separately without the rest. Thanks Michal Michal Suchanek (6): s390/kexec_file: Don't opencode appended signature check. powerpc/kexec_file: Add KEXEC_SIG support. kexec_file: Don't opencode appended signature verification. module: strip the signature marker in the verification function. module: Use key_being_used_for for log messages in verify_appended_signature module: Move duplicate mod_check_sig users code to mod_parse_sig arch/powerpc/Kconfig | 11 +++++ arch/powerpc/kexec/elf_64.c | 14 ++++++ arch/s390/kernel/machine_kexec_file.c | 42 ++---------------- crypto/asymmetric_keys/asymmetric_type.c | 1 + include/linux/module_signature.h | 1 + include/linux/verification.h | 4 ++ kernel/module-internal.h | 2 - kernel/module.c | 12 +++-- kernel/module_signature.c | 56 +++++++++++++++++++++++- kernel/module_signing.c | 33 +++++++------- security/integrity/ima/ima_modsig.c | 22 ++-------- 11 files changed, 113 insertions(+), 85 deletions(-) -- 2.31.1 _______________________________________________ kexec mailing list kexec@lists.infradead.org http://lists.infradead.org/mailman/listinfo/kexec
