Tested on alpha, amd64, i386, macppc, and sparc64 (thanks naddy, mpi, and okan!). Idea discussed for some time; committing now for further testing. ok deraadt Don't munge PID and TID together, since the way GDB displays them isn't very 2012-04-12T12:37:40Z kettenis kettenis@openbsd.org 2012-04-12T12:37:40Z urn:sha1:0bb3a4c4c61989e86201e5a693c30094618e4966 helpful. Just provide the TID instead. Properly recognize threads in OpenBSD core dumps. 2011-12-31T22:44:50Z kettenis kettenis@openbsd.org 2011-12-31T22:44:50Z urn:sha1:5b35567920fb4e4a8ca34bc4eace4a677de8bbff Teach bfd and gdb about the upcoming ELF core dumps. 2009-03-05T19:41:32Z kettenis kettenis@openbsd.org 2009-03-05T19:41:32Z urn:sha1:598a9ff7577b2e3bf65aff41dd6a6d52092e1d3b Merge conflicts, bringing our changes back in: 2004-11-02T20:44:57Z miod miod@openbsd.org 2004-11-02T20:44:57Z urn:sha1:007c2a4539b8b8aaa95c5e73e77620090abe113b - extra $(SHELL) and sugar for make (so that files not mode +x still work) - safer temp file handling - our W^X binary layout changes in ld - OpenBSD policy for library file selection in ld - arm and m88k changes which were not merged in time for official 2.15 - bfd core file handling - a couple typos New for 2.15: - ld(1) and as(1) manpages now generated at build time - binutils/stabs.c reverted to use our in-tree libiberty for now - we still use our VIA C3 crypto code over stock binutils, as it recognizes more instructions - new emulations for OpenBSD on mips64 machines, to help OpenBSD/sgi - relaxed %f# handling in gas on OpenBSD/sparc64 (same as was in 2.14) Tested on all platforms by various people; special thanks to sturm@ and otto@.

This removes the execute permission from readonly data. This constrains the executable region to portions of the executable which need to be executable. Note: not all processors or mmus are capable of -X protection at the page level, but should handle ELF images which specify specific RWX protections on each section.
