New Revision: 337963
URL: https://svnweb.freebsd.org/changeset/base/337963
Log:
MFC r337569: readelf: display NT_GNU_PROPERTY_TYPE_0 note name
NT_GNU_PROPERTY_TYPE_0 in a .note.gnu.property section "contains a
program property note which describes special handling requirements
for linker and run-time loader." (from the System V Application Binary
Interface - Linux Extensions")
Intel CET uses two processor-specific program properties in
NT_GNU_PROPERTY_TYPE_0: GNU_PROPERTY_X86_FEATURE_1_IBT to indicate that
all executable sections are compatible with Indirect Branch Tracking,
and GNU_PROPERTY_X86_FEATURE_1_SHSTK to indicate that sections are
compatible with shadow stack.
A later change should add decoding of the individual properties.
