fd4cdc438b7740007b06ea97431cc724e9aae185 - rtld: fix dependencies for rtld-libc

Fri, 08 Aug 2025 11:30:16 +0200

rtld: fix dependencies for rtld-libcPreviously we (appropriately, but incorrectly) attempted to depend onLIBC_NOSSP_PIC and LIBSYS_PIC for rtld_libc.a. Unfortunately,variables in dependency lists are expanded at parse time and thosevariables are defined in bsd.libnames.mk which *must* be included bybsd.{lib,prog}.mk. As such, they were undefined and thus expanded tothe empty string resulting in no dependency with predictable and highlyconfusing results.Move the declaration of these dependencies to after the include ofbsd.prog.mk and add comments on both side in hopes of keeping any futuredependencies in sync.Reviewed by: kibDifferential Revision: https://reviews.freebsd.org/D51790 List of files: /freebsd/libexec/rtld-elf/Makefile

Mon, 13 May 2024 07:23:50 +0200

Add a build knob for _FORTIFY_SOURCEIn the future, we will Default to _FORTIFY_SOURCE=2 if SSP is enabled,otherwise default to _FORTIFY_SOURCE=0. For now we default it to 0unconditionally to ease bisect across older versions without the newsymbols, and we'll put out a call for testing.include/*.h include their ssp/*.h equivalents as needed based on theknob. Programs and users are allowed to override FORTIFY_SOURCE in theirMakefiles or src.conf/make.conf to force it off.Reviewed by: des, markjRelnotes: yesSponsored by: StormshieldSponsored by: Klara, Inc.Differential Revision: https://reviews.freebsd.org/D32308 List of files: /freebsd/libexec/rtld-elf/Makefile

Stop #defining FREEBSD_ELFThis was originally used (along with FREEBSD_AOUT) to prefer the useof ELF in various tools instead of a.out as part of the a.out to ELFtransition in the 3.x days. The last use of it was removed from in commit 66422f5b7a1a6055f0b2358268eb902aab6e2e3e back in2002, but various files still #define it.Reviewed by: kevans, imp, emasteSponsored by: DARPADifferential Revision: https://reviews.freebsd.org/D42964 List of files: /freebsd/libexec/rtld-elf/Makefile

rtld: don't add extraneous -L directory when MK_TOOLCHAIN == nortld's Makefile used to add -L${LIBDIR} to LDFLAGS when MK_TOOLCHAIN wasno. This was done as part of a change to fix building rtld withMK_TOOLCHAIN == no (although I'm not sure this part was necessary).In any case as of 5f2e84015da7 libc_pic.a is built independent of theMK_TOOLCHAIN setting and the main part of the workaround has alreadybeen removed. Remove the rest now.This reverts commit c0f5aeb0329d71e6b02379133c0c9c0145c9afea.Reviewed by: jrtc27Sponsored by: The FreeBSD FoundationDifferential Revision: https://reviews.freebsd.org/D39938 List of files: /freebsd/libexec/rtld-elf/Makefile

Mon, 28 Dec 2020 09:44:25 +0100

rtld-elf: link libcompiler_rt on all architecturesStatically link rtld-elf with libcompiler_rt on all architectures sothat we don't need to try to pick and choose the bits we need from itfor each architecture (we now leave that to the linker). 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/libexec/rtld-elf/Makefile

7cc42f6d25ef2e19059d088fa7d4853fe9afefb5 - Do a sweep and remove most WARNS=6 settings

Thu, 01 Oct 2020 03:10:51 +0200

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.

[PowerPC64LE] Use a shared LIBC_ARCH for powerpc64le.Given that we have converted to ELFv2 for BE already, endianness is the onlydifference between the two ARCHs.As such, there is no need to differentiate LIBC_ARCH between the two.Combining them like this lets us avoid needing to have two copies of severalbits for no good reason.Sponsored by: Tag1 Consulting, Inc.
