Subject: [PATCH] libebl: Allow SHT_NOTE as relocation target type.
Date: Wed, 21 Feb 2018 15:36:00 -0000	[thread overview]
Message-ID: <1519227364-17006-1-git-send-email-mark@klomp.org> (raw)

eu-elflint uses ebl_check_reloc_target_type to determine whether a section
is a valid relocation target. In Fedora rawhide there are new ELF notes
(annobin) which have relocations against them in ET_REL files. eu-elflint
currently flags these as invalid. It looks like that is not correct.
I cannot find any reason an SHT_NOTE section cannot have relocations
against it. So this patch allows them.
