MFS r352754: Add WITH_PIE knob to build Position Independent ExecutablesMFC r344179: Add WITH_PIE knob to build Position Independent ExecutablesBuilding binaries as PIE allows the executable itself to be loaded at arandom address when ASLR is enabled (not just its shared libraries).With this change PIE objects have a .pieo extension and INTERNALLIBlibraries libXXX_pie.a.MK_PIE is disabled for some kerberos5 tools, Clang, and Subversion, asthey explicitly reference .a libraries in their Makefiles. These canbe addressed on an individual basis later. MK_PIE is also disabled forrtld-elf because it is already position-independent using bespokeMakefile rules.Currently only dynamically linked binaries will be built as PIE.MFC r344181: Fix Makefile conditional after r344179MFC r344182: Use make's :tl instead of checking "no" and "NO"MFC r344189: Fixup bsd.prog.mk after r344182MFC r344211: wlandebug: disable PIE to fix build failurelibifconfig is built as a static-only PRIVATELIB (and there is no _pie.aversion) so disable PIE in libifconfig's consumer.r345489: Fix GNU objdump build under WITH_PIEExplicitly specified bare .a libraries need ${PIE_SUFFIX}.r345490: Apply WITH_PIE changes to other binutils componentsFollowon to r345489, explicitly specified bare .a libraries need${PIE_SUFFIX} (although these still built).r345778: Fix gdb/kgdb build under WITH_PIEExplicitly specified bare .a libraries need ${PIE_SUFFIX}.Approved by: re (gjb)Sponsored by: The FreeBSD Foundation List of files: /freebsd-12.1/gnu/usr.bin/binutils/objcopy/Makefile

5608fd23 - Revert r267233 for now. PIE support needs to be reworked.

Tue, 19 Aug 2014 15:04:32 +0000

Revert r267233 for now. PIE support needs to be reworked.1. 50+% of NO_PIE use is fixed by adding -fPIC to INTERNALLIB and other build-only utility libraries.2. Another 40% is fixed by generating _pic.a variants of various libraries.3. Some of the NO_PIE use is a bit absurd as it is disabling PIE (and ASLR) where it never would work anyhow, such as csu or loader. This suggests there may be better ways of adding support to the tree. Many of these cases can be fixed such that -fPIE will work but there is really no reason to have it in those cases.4. Some of the uses are working around hacks done to some Makefiles that are really building libraries but have been using bsd.prog.mk because the code is cleaner. Had they been using bsd.lib.mk then NO_PIE would not have been needed.We likely do want to enable PIE by default (opt-out) for non-tree consumers(such as ports). For in-tree though we probably want to only enable PIE(opt-in) for common attack targets such as remote service daemons and setuidutilities. This is also a great performance compromise since ASLR is expectedto reduce performance. As such it does not make sense to enable it in allutilities such as ls(1) that have little benefit to having it enabled.Reported by: kib List of files: /freebsd-12.1/gnu/usr.bin/binutils/objcopy/Makefile

864c53ea - In preparation for ASLR [1] support add WITH_PIE to support building with -fPIE.

Sun, 08 Jun 2014 17:29:31 +0000

In preparation for ASLR [1] support add WITH_PIE to support building with -fPIE.This is currently an opt-in build flag. Once ASLR support is ready and stableit should changed to opt-out and be enabled by default along with ASLR.Each application Makefile uses opt-out to ensure that ASLR will be enabled bydefault in new directories when the system is compiled with PIE/ASLR. [2]Mark known build failures as NO_PIE for now.The only known runtime failure was rtld.[1] http://www.bsdcan.org/2014/schedule/events/452.en.htmlSubmitted by: Shawn Webb Discussed between: des@ and Shawn Webb [2] List of files: /freebsd-12.1/gnu/usr.bin/binutils/objcopy/Makefile

ab5ad3a4 - Restructure the binutils hierarchy somewhat in order to better

Thu, 12 Mar 1998 02:55:43 +0000

Restructure the binutils hierarchy somewhat in order to bettersupport building it for variant architectures. It was alreadybecoming clear that the former structure was too rigid and didn'tscale well.The usual sort of makefile magic arranges to .include an architecturespecific makefile "Makefile.${MACHINE_ARCH}" in each directorywhere it exists. Also, sources will be found in each subdirectory"${MACHINE_ARCH}" that exists. This is all taken care of automaticallyby the top level "Makefile.inc0".This all seems to work right for the i386 now. I have also convertedthose alpha pieces already present to the new schema as best Icould.Also: change the BINDIR on the i386 to /usr/libexec/elf for "ar"and "ranlib". They are not object format independent enough toput into /usr/bin. List of files: /freebsd-12.1/gnu/usr.bin/binutils/objcopy/Makefile

Add bmakefiles for building binutils from the contrib tree.This finishes up the binutils import. But I am leaving it disabledin "src/gnu/usr.bin/Makefile" for now. It is not used by anythingyet, so I'll take this opportunity to run one more round of testsbefore enabling it. List of files: /freebsd-12.1/gnu/usr.bin/binutils/objcopy/Makefile
