Compilers mayemit calls to support functions in this library, but because of the useof the linker flag -nostdlib for rtld's special needs, the library isnot linked as normal.Previously we had two different solutions. On some architectures, wewere able to extract reimplementations of the necessary builtinfunctions from our special build of libc. On ARM, we just linkedlibcompiler_rt.This is motivated by the same issue as D26199 and D27665, but should bea simpler solution that will apply to all architectures.Reviewed by: arichardson, kibSponsored by: Dell EMC IsilonDifferential Revision: https://reviews.freebsd.org/D27736 List of files: /freebsd-13.1/libexec/rtld-elf/Makefile Mon, 28 Dec 2020 08:44:25 +0000 Ryan Libby <rlibby@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-13.1/libexec/rtld-elf/Makefile#7cc42f6d Do a sweep and remove most WARNS=6 settingsRepeating the default WARNS here makes it slightly more difficult toexperiment with default WARNS changes, e.g. if we did something absolutelybananas and introduced a WARNS=7 and wanted to try lifting the default tothat.Drop most of them; there is one in the blake2 kernel module, but I suspectit should be dropped -- the default WARNS in the rest of the build doesn'tcurrently apply to kernel modules, and I haven't put too much thought intowhether it makes sense to make it so.

This was causingsymbol such as __libc_interposing and all the pthread stubs to be includedin RTLD even though they are not required. It turns out most of thesedependencies can easily be avoided by providing overrides inside of rtld.This change is motivated by CHERI, where we have an experimental ABI thatrequires additional relocation processing to allow the use of functionpointers inside of rtld. Instead of adding this self-relocation code toRTLD I attempted to remove most function pointers from RTLD and discoveredthat most of them came from the libc dependencies instead of being actuallyused inside rtld.A nice side-effect of this change is that rtld is now 22% smaller on amd64. text data bss dec hex filename0x21eb6 0xce0 0xe60 145910 239f6 /home/alr48/ld-elf-x86.before.so.10x1a6ed 0x728 0xdd8 113645 1bbed /home/alr48/ld-elf-x86.after.so.1The number of R_X86_64_RELATIVE relocations that need to be processed onstartup has also gone down from 368 to 187 (almost 50% less).Reviewed By: kibDifferential Revision: https://reviews.freebsd.org/D20663 List of files: /freebsd-13.1/libexec/rtld-elf/Makefile Sun, 30 Jun 2019 11:49:58 +0000 Alex Richardson <arichardson@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-13.1/libexec/rtld-elf/Makefile#e3e21edb ld-elf.so: make LD_DEBUG always functional.This causes some increase of the dynamic linker size, but benefits ofavoiding compiling private copy or the linker when debugging isrequired. definitely worth it.The dbg() calls can be compiled out by defining LD_NO_DEBUG symbol.Sponsored by: The FreeBSD FoundationMFC after: 1 week List of files: /freebsd-13.1/libexec/rtld-elf/Makefile Sun, 14 Apr 2019 18:04:53 +0000 Konstantin Belousov <kib@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-13.1/libexec/rtld-elf/Makefile#09b47fc1 revert r341429 "disable BIND_NOW in libc, libthr, and rtld"r345620 by kib@ fixed the rtld issue that caused a crash at startupduring resolution of libc's ifuncs with BIND_NOW.PR: 233333Sponsored by: The FreeBSD Foundation List of files: /freebsd-13.1/libexec/rtld-elf/Makefile Thu, 28 Mar 2019 02:12:32 +0000 Ed Maste <emaste@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-13.1/libexec/rtld-elf/Makefile#bcf99d2d 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.
