19fe57fd - libssp: don't compile with -fstack-protector*

Sat, 14 Mar 2020 15:15:27 +0000

libssp: don't compile with -fstack-protector*This similarly matches what we do in libc; compiling libssp with-fstack-protector* is actively harmful. For instance, if the canary ctorends up with a stack protector then it will trivially trigger a falsepositive as the canary's being initialized.This was noted by the reporter as irc/ircd-hybrid started crashing at startafter our libssp was MFC'd to stable/11, as its build will explicitly linkin libssp. On FreeBSD, this isn't necessary as SSP bits are included inlibc, but it should absolutely not trigger runtime breakage -- it does meanthat the canary will get initialized twice, but as this is happening earlyon in application startup it should just be redundant work.Reported by: Tod McQuillin MFC after: 3 days List of files: /freebsd-14.2/lib/libssp/Makefile

cd0d51ba - Provide libssp based on libc

Sat, 04 Jan 2020 20:19:25 +0000

Provide libssp based on libcFor libssp.so, rebuild stack_protector.c with FORTIFY_SOURCE stubs that justabort built into it.For libssp_nonshared.a, steal stack_protector_compat.c from^/lib/libc/secure and massage it to maintain that __stack_chk_fail_localis a hidden symbol.libssp is now built unconditionally regardless of {WITH,WITHOUT}_SSP in thebuild environment, and the gcclibs version has been disconnected from thebuild in favor of this one.PR: 242950 (exp-run)Reviewed by: kib, emaste, pfg, Oliver Pinter (earlier version)Also discussed with: kanMFC after: 2 weeksDifferential Revision: https://reviews.freebsd.org/D22943 List of files: /freebsd-14.2/lib/libssp/Makefile
