* elf/rtld.c (dl_main): Take new option --verify when run directly.
In verify mode, exit with status zero iff the argument object's
PT_INTERP matches argv[0].
* elf/ldd.sh.in: Use ${RTLD} --verify and only run the program if it
exits with zero status. This makes `ldd' secure again.
Fri Jul 26 22:49:58 1996 Ulrich Drepper <drepper@cygnus.com>
* elf/rtld.c (dl_main): Implement LD_TRACE_LOADED_OBJECTS
environment variable handling. This makes the dynamic linker
only print loaded libraries and quit.
* elf/ldd.sh.in: Don't use `rtld --list' but instead
LD_TRACE_LOADED_OBJECTS environment variable to print needed
objects.
Sat Jul 27 02:03:26 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* db/makedb.c (main): Print version on stdout, not stderr. Don't exit
after printing version until after doing usage for --help.
(long_options, main, usage): Rename -l/--lowercase option to
-f/--fold-case (-f matches sort).
Sat Jul 27 04:32:31 1996 Ulrich Drepper <drepper@cygnus.com>
* db/makedb.c: New file. Implement program to create simple <db.h>
database from textual input. This will be used for nss_db.
Sat Jul 27 01:24:05 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* sunrpc/rpc/auth_unix.h: Fix misapplied patches in last changes.
* sunrpc/rpc/pmap_clnt.h: Likewise.
* sunrpc/rpc/auth.h: Likewise.
* sunrpc/rpc/pmap_rmt.h: Likewise.
* sunrpc/rpc/rpc_msg.h: Likewise.
Sat Jul 27 04:37:34 1996 Ulrich Drepper <drepper@cygnus.com>
* string/string.h (strndupa): Change to use return value of
`memcpy' for more performance.
* string/strndup.c: Likewise.
* string/string.h (strdupa): Don't call __builtin_alloca in argument.
This might lead to problems.
(strndupa): Likewise.
