*	ld.so: Do not export free/calloc/malloc/realloc functions [BZ #25486]	Florian Weimer	2020-02-15	1	-6/+0
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Exporting functions and relying on symbol interposition from libc.so makes the choice of implementation dependent on DT_NEEDED order, which is not what some compiler drivers expect. This commit replaces one magic mechanism (symbol interposition) with another one (preprocessor-/compiler-based redirection). This makes the hand-over from the minimal malloc to the full malloc more explicit. Removing the ABI symbols is backwards-compatible because libc.so is always in scope, and the dynamic loader will find the malloc-related symbols there since commit f0b2132b35248c1f4a80f62a2c38cddcc802aa8c ("ld.so: Support moving versioned symbols between sonames [BZ #24741]").

*	ld.so: Introduce struct dl_exception	Florian Weimer	2017-08-10	1	-0/+2
\| \| \| \| \| \|	This commit separates allocating and raising exceptions. This simplifies catching and re-raising them because it is no longer necessary to make a temporary, on-stack copy of the exception message.

*	ld.so: Remove __libc_memalign	Florian Weimer	2016-11-30	1	-4/+2
\| \| \| \| \| \| \|	It is no longer needed since commit 6c444ad6e953dbdf9c7be065308a0a777 (elf: Do not use memalign for TCB/TLS blocks allocation [BZ #17730]). Applications do not link against ld.so and will use the definition in libc.so, so there is no ABI impact.
*	Implement _dl_catch_error, _dl_signal_error in libc.so [BZ #16628]	Florian Weimer	2016-11-30	1	-0/+3
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This change moves the main implementation of _dl_catch_error, _dl_signal_error to libc.so, where TLS variables can be used directly. This removes a writable function pointer from the rtld_global variable. For use during initial relocation, minimal implementations of these functions are provided in ld.so. These are eventually interposed by the libc.so implementations. This is implemented by compiling elf/dl-error-skeleton.c twice, via elf/dl-error.c and elf/dl-error-minimal.c. As a side effect of this change, the static version of dl-error.c no longer includes support for the _dl_signal_cerror/_dl_receive_error mechanism because it is only used in ld.so.
*	Support PLT and GOT references in local PIC check	H.J. Lu	2015-10-14	1	-7/+7
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	Linker in binutils 2.26 and newer generate GOT references instead PLT references when -z now is passed to linker. We need to extend scripts/localplt.awk to allow PLT or GOT references. [BZ #19007] * scripts/localplt.awk: Also allow GOT references. * sysdeps/unix/sysv/linux/i386/localplt.data: Mark _Unwind_Find_FDE, calloc, memalign, realloc and __libc_memalign with "+ REL R_386_GLOB_DAT". * sysdeps/x86_64/localplt.data: Mark calloc, memalign, realloc and __libc_memalign with "+ RELA R_X86_64_GLOB_DAT".
*	Extend local PLT reference check	H.J. Lu	2015-07-29	1	-0/+19
	On x86, linker in binutils 2.26 and newer consolidates R__JUMP_SLOT with R__GLOB_DAT relocation against the same symbol. This patch extends local PLT reference check to support alternate relocations. [BZ #18078] * scripts/check-localplt.awk: Support alternate relocations. * scripts/localplt.awk: Also check relocations in DT_RELA/DT_REL sections. * sysdeps/unix/sysv/linux/i386/localplt.data: Mark free and malloc entries with + REL R_386_GLOB_DAT. * sysdeps/x86_64/localplt.data: New file.
