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.

Somewhat taken from FreeBSD. Manual page from OpenBSD.

skrll 4931e61023 Mark each object as printed as visited and then print.
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.

skrll 77fd7698f3 Make _rtld_pagesz of type size_t.

he 3b9a95def3 Um, the test for mips should use MACHINE_CPU, not MACHINE_ARCH. 2009-08-20 21:07:47 +00:00
he c93d22967f Don't try to call the (no longer defined) aout_ldd() function
if we're building for mips.
2009-08-20 21:06:17 +00:00
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.

mrg 0d6aaaf295 pull across the struct netbsd32_exec definition and use that in all
cases, since we never did 64 bit a.out.  now ldd on 32 bit a.out
at least tries to work, but fails (on sparc or sparc64, no idea yet
for x86) the same way that all dynamic a.out binaries fail.
2009-01-11 00:06:55 +00:00
mrg 32ae7959e8 make sure we set LIBISPRIVATE.
fixes build issues reported by moof.

mrg 9b688fed42 - rework this a bunch to make it work inside /rescue/ldd.
- fix alpha build.
2009-01-07 00:39:23 +00:00
mrg 648c936726 - get rid of building an a.out-happy ldd (but keep supporting a.out
binaries for the ELF version.)

- convert a.out, elf32 and elf64 support into convience libraries and
  link them right ones in.  if elf_ldd() fails on 64 bit platforms,
  try elf32_ldd() before aout_ldd().


now ldd on 64 bit platforms works for 32 bit binaries, aka PR#40199,
and it seems that all the issues from README are gone too.
