[HURD PATCH 0/7] $ORIGIN substitution in RPATH

[Jeremie Koenig <jk at jk dot fr dot eu dot org>]

Hi,

The ELF RPATH header (an executable-specific search path for shared libraries)
can include the special string $ORIGIN, which should be substituted with the
directory in which the binary resides. On Hurd this is not implemented yet;
the filename used is not available to a newly executed binary.

This series builds on Emilio's file_exec_file_name patches from last year and
is the libc counterpart to the Hurd patches posted here:

    http://lists.gnu.org/archive/html/bug-hurd/2011-08/msg00047.html

Emilio Pozuelo Monfort (2):
  Use the new file_exec_file_name RPC
  Add check for file_exec_file_name

Jeremie Koenig (5):
  Hurd startup: fetch the exec filename using exec_startup_get_info_2
  Hurd dl-origin.c: start with a copy of elf/dl-origin.c
  Hurd dl-origin.c: Use _hurd_init_filename if available
  Propagate _hurd_init_filename beyond dynamic loading
  _hurd_exec_file_name: canonicalize filename
