This commit was manufactured by cvs2svn to create tag

'RELENG_5_3_0_RELEASE'.

This commit was manufactured to restore the state of the 5.3-RELEASE image.

Support basename and path based constrained matches.

2004-05-24T01:24:13+00:00

eg:
	[foo]
	...

	matches any executable 'foo'

	[/usr/bin/foo/]
	...

	matches any executable under the directory /usr/bin/foo/

Exact matches continue to function as before.

Add initial support for compiling a special 32 bit version of

2004-03-21T01:21:26+00:00

ld-elf.so.1 on 64 bit systems.  Most of this involves using alternate
paths, environment variables and diagnostic messages.

The build glue is seperate.

Fix "warning: value computed is not used".

Change libmap.c:lm_init() to return a status value; 0 for success

2003-09-13T21:43:08+00:00

(libmap available) and 1 for failure.  Assign this return to the
global 'libmap_disable' variable in rtld.c.

This totally prevents any libmap functions from being called after
lm_init() if no config file is present.

Include libmap.h for prototypes.

2003-06-18T05:31:08+00:00

Provide function entry debugging messages.

Don't post-increment pointers inside a loop conditional.

2003-05-30T00:49:16+00:00

While I'm here:
- Let lm_add() call strdup() on its own behalf.
- Use a temporary pointer when parsing constraints; only set the
  constraint pointer on a totally successful match.

Allow threading libraries to register their own locking

2003-05-29T22:58:26+00:00

implementation in case default one provided by rtld is
not suitable.

Consolidate various identical MD lock implementation into
a single file using appropriate machine/atomic.h.

- Use xmalloc() and xstrdup() instead of malloc() and strdup().

2003-05-19T07:10:12+00:00

- Add a global mapping if we have a successful constrained match.
