christos c686ebaab6 rtld expects an absolute path in execname provided via AUXV in order to 
handle $ORIGIN properly and checks for that. Since we are calling its guts
directly, provide one.

kamil f4a6ea5271 Disable SANITIZER for ldd(1) 
These utilities (elf32, elf32_compat, elf64, liblldb) share code with the
ELF dynamic loader that is not being sanitized and its symbols are
installed into sanitized programs (in particular __tls_get_addr()).

Additionally libldd is used in rescue that is not expected to be sanitized
as of today.

macallan da8b2f53fd apply kludge to make this more or less work on mips64 with n32 userland 
with this ldd can handle both 64 and n32 binaries ( previously it would do 64
only ), o32 support is still broken
Someone more familiar with this code needs to fix this properly.

plunky d1fbb9e17f move the build of ldd binary to a subdir in order to allow 
explict ordering. This makes "make all" work the same as
"make dependall"

joerg 8fa6585514 Block signals when using the exclusive lock. 2011-03-29 20:56:35 +00:00
joerg cb1cd7e860 Add basic locking to ld.elf_so. 2011-03-25 18:07:04 +00:00
joerg aad599979d Add TLS support infrastructure. For dynamic binaries, ld.elf_so exports 
_rtld_tls_allocate and _rtld_tls_free. libpthread uses this functions to
setup the thread private area of all new threads. ld.elf_so is
responsible for setting up the private area for the initial thread.
Similar functions are called from _libc_init for static binaries, using
dl_iterate_phdr to access the ELF Program Header.

Add test cases to exercise the different TLS storage models. Test cases
are compiled and installed on all platforms, but are skipped on
platforms not marked for TLS support.

This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.

It is inspired by the TLS support in FreeBSD by Doug Rabson and the
clean ups of the DragonFly port of the original FreeBSD modifications.

Fixes PR/42811.

As a side effect the libraries are printed in, imo, a better order.

mrg f4f977dbc5 make this actually build on mips64. 2009-12-15 04:06:43 +00:00
mrg 118cb193d7 - adjust the logic for compat ldd: add an elf32_compat module and arrange 
for mips64 to build this with MLIBDIR set to o32
- make mips64 ldd call elf32_compat_ldd as well
- make mips64 elf64 set MLIBDIR to 64
- don't need ld.elf_so's Makefile.ld32 files anymore (they are going away
  soon anyway)

tested on amd64 and sparc64, and an earlier version tested on mips64.

if we're building for mips.

he b233b36efa Don't include <a.out.h> unless it's needed, and don't build 
the aout subdir if on mips.  Fixes build for mips ports.

mrg e53a76c628 rework the main loop and handlers: 
- open() and close() the file in the main loop
- pass the fd down into the handlers
- use _rtld_error() in ELFNAME(ldd)

this fixes PR#40543 and also makes error messages look better.
