When allocating TLS and DTV, make sure that any unused slots in the DTV

2005-03-30T08:28:26Z

are initialised to zero. When freeing TLS, don't attempt to free DTV slots which were not used. Pointed out by: Joerg Sonnenberger X-MFC-After: After the branch, probably

If "dangerous" environment variables (LD_PRELOAD, LD_LIBMAP,

2005-03-24T10:12:29Z

LD_LIBMAP_DISABLE, LD_LIBRARY_PATH) are used, then make sure the libraries being loaded aren't on a noexec-mounted filesystem. This is a compromise position: I'm assuming that nobody will be silly enough to set the noexec mount flag on part of the default library path, in order to avoid adding extra overhead into the common case (where those environment variables aren't used).

Add locking code for tls routines.

2005-03-20T23:28:25Z

Attempt to free any static TLS space used by a shared library when it

2005-02-27T12:55:40Z

is unloaded. This allows applications which load and unload libraries like libGL.so.1 several times to work properly. MFC after: 2 days

Description from Dan:

2005-02-04T02:46:41Z

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 PR: bin/74471 Submitted by: Dan Nelson MFC after: 2 weeks

Do the TLS offset allocations before relocations, as otherwise there

2004-11-02T09:42:21Z

can be overlap in the TLS offsets, if the relocations are done in a certain order. Approved by: dfr, grehan (mentor)
