META MODE: Don't create .meta files when symlinking sources into the obj directory.

2015-11-25T19:44:43Z

Tracking these leads to situations where meta mode will consider the file to be out of date if /bin/sh or /bin/ln are newer than the source file. There's no reason for meta mode to do this as make is already handling the rebuild dependency fine. Sponsored by: EMC / Isilon Storage Division

Reduce overlinking

Revert r267233 for now. PIE support needs to be reworked.

2014-08-19T15:04:32Z

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 setuid utilities. This is also a great performance compromise since ASLR is expected to reduce performance. As such it does not make sense to enable it in all utilities such as ls(1) that have little benefit to having it enabled. Reported by: kib

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

2014-06-08T17:29:31Z

This is currently an opt-in build flag. Once ASLR support is ready and stable it 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 by default 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.html Submitted by: Shawn Webb Discussed between: des@ and Shawn Webb [2]

get rid of testing explicitly for clang (using ${CC:T:Mclang}) in individual Makefiles. Instead, use the following extra macros, for use with clang: - NO_WERROR.clang (disables -Werror) - NO_WCAST_ALIGN.clang (disables -Wcast-align) - NO_WFORMAT.clang (disables -Wformat and friends) - CLANG_NO_IAS (disables integrated assembler) - CLANG_OPT_SMALL (adds flags for extra small size optimizations) As a side effect, this enables setting CC/CXX/CPP in src.conf instead of make.conf!
