8c6a035ead Fix a malloc overrun in 32-bit compat libmap lookup code. 2006-01-31 06:08:28 +00:00

5b08cb0449 Description from Dan:
Another handy libmap patch.  Lets you do stuff like this:

	LD_LIBMAP="libpthread.so.1=libthr.so.1" mythreadedapp

	If you already have a program-specific override in libmap.conf, note
	that you must use a program-specific override in LD_LIBMAP:

	LD_LIBMAP="[mythreadedapp],libpthread.so.1=libthr.so.1" mythreadedapp

966efcc767 Support basename and path based constrained matches.
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.

c905e45dc0 Add initial support for compiling a special 32 bit version of
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.

4402996dea Change libmap.c:lm_init() to return a status value; 0 for success
(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.

1340fc1015 Don't post-increment pointers inside a loop conditional.
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.

6d5d786f80 Allow threading libraries to register their own locking
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.

3467e8b8a0 - Use xmalloc() and xstrdup() instead of malloc() and strdup().
- Add a global mapping if we have a successful constrained match.

29ade36225 Dynamic object dependency mapping: libmap.
This is an optional feature, disabled by default.

This will be useful to people testing the various POSIX threading
libraries under -CURRENT but can easily serve other needs.
