[BZ #12393]
* elf/dl-load.c (is_trusted_path): Remove unnecessary test.
(is_trusted_path_normalize): Skip initial colon. Append slash
to empty buffer. Duplicate is_trusted_path code but allow
constructed patch to be prefix.
(is_dst): Allow $ORIGIN followed by /.
(_dl_dst_substitute): Correct clearing of check_for_trusted.
Correct testing of result of is_trusted_path_normalize
(decompose_rpath): Fix warning.

[BZ #12393]
* elf/dl-load.c (fillin_rpath): Move trusted path check...
(is_trusted_path): ...to here.
(is_trusted_path_normalize): Wrapper for /../ and /./ normalization.
(_dl_dst_substitute): Verify expanded $ORIGIN path elements
using is_trusted_path_normalize() in setuid scripts.
2011-03-14 Andreas Schwab <schwab@redhat.com>
* elf/dl-load.c (_dl_dst_substitute): When skipping the first
rpath element also skip the following colon.
(expand_dynamic_string_token): Add is_path parameter and pass
down to DL_DST_REQUIRED and _dl_dst_substitute.
(decompose_rpath): Call expand_dynamic_string_token with
non-zero is_path. Ignore empty rpaths.
(_dl_map_object_from_fd): Call expand_dynamic_string_token
with zero is_path.
2011-03-06 Ulrich Drepper <drepper@gmail.com>
* elf/dl-load.c (_dl_map_object): If we are looking for the first
to-be-loaded object along a path to loader is ld.so.
