Bug ID: 25225
Summary: ld.so fails to link on x86 if GCC defaults to
-fcf-protection
Product: glibc
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
If GCC defaults to -fcf-protection, we need to automatically assume
--enable-cet. Otherwise ld.so will use CET functionality (as __CET__ is
defined), but it has not been compiled and linked into ld.so due to the
--disable-cet default. Therefore linking ld.so fails.
