/* opendir() must not accidentally open something other than a directory.

Some OS's have kernel support for that, some don't. In the worst

case we have to stat() before the open() AND fstat() after.
|
|
|
|
|

We have to test at runtime for kernel support since libc may have

been compiled with different headers to the kernel it's running on.

This test can't be done reliably in the general case. We'll use

/dev/null, which if it's not a device lots of stuff will break, as

a guinea pig. It may be missing in chroot environments, so we

make sure to fail safe. */

Update.
Thu Aug 8 01:41:43 1996 Ulrich Drepper <drepper@cygnus.com>
* elf/Makefile: Undo change of Tue Aug 6 14:27:11 1996.
* elf/dl-support: Add definition of `_dl_sysdep_read_whole_file'.
Thu Aug 8 01:15:59 1996 Ulrich Drepper <drepper@cygnus.com>
* sysdeps/i386/fpu_control.h (_FPU_DEFAULT, _FPU_IEEE): Set
to 0x137f to allow long double operations.
Sun Aug 4 13:12:05 1996 Richard Henderson <rth@tamu.edu>
Bug Fixes:
* nss/nsswitch.c (_res): Remove redundant variable definition.
The real one is in resolve/res_init.c, and having both prevents
using -fno-common when building the shared library.
* sunrpc/rpc_prot.c (_null_auth): Same. Original is in rpc_common.c.
* sysdeps/unix/sysv/linux/alpha/brk.S: When PIC, define __curbrk as
a .bss object not a COMMON symbol.
* sysdeps/alpha/bsd-_setjmp.S, sysdeps/alpha/bsd-setjmp.S: Must load
$gp before referencing __sigsetjmp symbol. Retain LITUSE for same.
Optimizations:
* sysdeps/alpha/strlen.S: Rearrange first-word setup and thense the
main loop for better dual-issue on EV5. Rearrange binary search to
pipeline better and trim one instruction.
Cosmetic Changes:
* time/localtime.c (localtime_r): Move lock declaration back next to
the comment where it was before the 960724 change.
* INSTALL, manual/maint.texi: alpha-gnu-linux -> alpha-ANYTHING-linux.
The second word is supposed to be the hardware manufacturer.
* sysdeps/alpha/_mcount.S: Retain LITUSE for __mcount.
* sysdeps/alpha/setjmp.S: Retain LITUSE for __sigsetjmp_aux.
* sysdeps/alpha/divrem.h: More local labels, retain LITUSE for _mcount.
* sysdeps/alpha/alphaev5/add_n.S, sysdeps/alpha/alphaev5/lshift.S,
sysdeps/alpha/alphaev5/rshift.S, sysdeps/alpha/alphaev5/sub_n.S:
Same cleanups as with EV4 GMP stuff.
Tue Jul 25 03:30:56 1996 Richard Henderson <rth@tamu.edu>
* sysdeps/unix/sysv/linux/Makefile [misc] (sysdep_routines): Add clone.
* sysdeps/unix/sysv/linux/alpha/clone.S: New file.
* sysdeps/unix/sysv/linux/i386/clone.S: New file.
Sun Aug 4 00:12:41 1996 David Mosberger-Tang <davidm@azstarnet.com>
* sysdeps/unix/sysv/linux/gnu/types.h: Declare __fd_mask as
`unsigned long'.
* misc/sys/select.h: Declare fd_mask as alias of __fd_mask.
Sat Aug 3 16:20:02 1996 David Mosberger-Tang <davidm@azstarnet.com>
* sysdeps/unix/sysv/linux/alpha/ioperm.c (platform): Add entry for
Mikasa.
* socket/sys/socket.h (send, __send, sendto): Declare buffer
pointer as __const.
* string/tester.c (main): Test stpncpy.
* sysdeps/generic/stpncpy.c (__stpncpy): Fix so it works without
segfault when called with an N that is not a multiple of four and
src[N-1]=='\0'.
* misc/syslog.c (LogType): New variable.
(openlog): If connect() with SOCK_DGRAM fails with EPROTOTYPE,
try again with SOCK_STREAM (the Linux syslogd uses a socket of the
latter type).
(vsyslog): When LogType==SOCK_STREAM, also send ASCII NUL
terminator as a record-delimiter. If __send(LogFile) fails,
call closelog() so logfile gets re-opened next time.
Wed Aug 7 15:15:14 1996 Ulrich Drepper <drepper@cygnus.com>
* elf/dl-open (_dl_open): Add cast to avoid warning.
* manual/memory.texi: Improve some examples to give readers better
advice: Use `stpcpy' instead of `strcat' if possible.
* manual/string.texi: Document `strtok_r' and `strtok'.
* sunrpc/Makefile: Move `+gccwarn' definition before inclusion
of Makeconfig.
[$(cross-compiling)=no]: Change test before making librpcsvc
to this from $(cross-compile).
Reported by Andreas Schwab.
Tue Aug 6 14:27:11 1996 Ulrich Drepper <drepper@cygnus.com>
* elf/Makefile (routines): Move dl-sysdep to here...
(rtld-routines): ...from here. This should make static linking
work again.
* locale/setlocale.c: Add local variable `lock' and add code to
`setlocale' to avoid simultaneous changing of global data.
* catgets/catgets.c (catopen): Use `__strdup' instead of `strdup'.
* catgets/open_catalog (__open_catalog): Use `__stpcpy', `__open',
`__fstat', `__read', `__mmap', `__munmap' and `__close' instead
of unprotected names.

Mon Sep 23 15:31:04 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu>

variable `top_srcdir' in libc; use $(..) instead.
