* crunchgen: remove -dc from linker invocationFangrui Song2022-02-091-4/+2
| | | | | | | | | | | | | | | | | | | | | In GNU ld and ld.lld, -dc is used with -r to allocate space to COMMON symbols. It is presumably to work around legacy code which cannot handle COMMON symbols in relocatable output. ld.lld may remove -dc or make it a no-op for the 15.0.0 release. As of 7420b323a014 crunch/crunchide does not require -dc, as the symbol hiding technique no longer relied on making symbols local. In addition -fno-common is now the default in Clang and GCC, so -dc serves no purpose as the compiler does not generate COMMON symbols anyway. See https://maskray.me/blog/2022-02-06-all-about-common-symbols for more detail on common symbols. Reviewed by: emaste MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D34215

* various: general adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-273-3/+10
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

* crunchide: report explicit error for combined string tableEd Maste2016-11-171-0/+4
| | | | | | | | | | | | | | | | | Some tools produce objects with a combined strtab and shstrtab. These objects are not supported by crunchide since it rewrites the symtab and strtab to "hide" symbols. This invalidates section header offsets into a combined strtab/shstrtab. In the future we could support these objects (by ensuring that we retain unmodified section name strings in the output .strtab, and then rewriting each section header's sh_name).

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 Notes: svn path=/head/; revision=270168

However, this is not specified in the ELF standards, and linkers may generate different layouts when doing partial linking (-r). This change is required to build FreeBSD with mclinker or the gold linker.
