Description H.J. Lu 2010-01-23 16:39:09 UTC
On Intel Core i7, I saw

/var/log/messages-20100110:Jan  8 14:39:35 gnu-6 klogd: gdbserver[20988] trap
invalid opcode ip:3df7414959 sp:7fffc77d9808 error:0 in
ld-2.11.1.so[3df7400000+1e000]

when I did "make check" in gdb. The corresponding code is

_dl_x86_64_restore_sse:
# ifdef HAVE_AVX_SUPPORT
        cmpl    $0, L(have_avx)(%rip)
        js      L(no_avx6)

        vmovdqa %fs:RTLD_SAVESPACE_SSE+0*YMM_SIZE, %ymm0

        vmovdqa %fs:RTLD_SAVESPACE_SSE+7*YMM_SIZE, %ymm7
        ret

in sysdeps/x86_64/dl-trampoline.S. It seems like L(have_avx)
is 0, instead of -1, I don't see how it can happen. Maybe
gdbserver is a special case.
Comment 1 H.J. Lu 2010-01-25 14:06:35 UTC
To reproduce on Fedora 12/x86-64:

1. Get the current gdb.
2. Build gdb.
3. Run "make check RUNTESTFLAGS=server-run.exp".  It will
fail at random:

Comment 2 H.J. Lu 2010-01-26 23:40:57 UTC
_dl_x86_64_save_sse was never called. However, sometimes
_dl_x86_64_restore_sse is called via

gdb) bt

gdb uses

  child_pid = clone (linux_tracefork_child, stack + STACK_SIZE,
                     CLONE_VM | SIGCHLD, stack + STACK_SIZE * 2);


static int
linux_tracefork_child (void *arg)
{
  ptrace (PTRACE_TRACEME, 0, 0, 0);
  kill (getpid (), SIGSTOP);
  clone (linux_tracefork_grandchild, arg + STACK_SIZE,
         CLONE_VM | SIGCHLD, NULL);
  exit (0);
}

Since 2 processes share the TLS and memory space, there is
a race condition. Maybe gdb shouldn't use CLONE_VM for x86-64
or use "-z now" for linking.
Comment 3 H.J. Lu 2010-01-27 00:04:17 UTC
With CLONE_VM, THREAD_GETMEM (THREAD_SELF, header.rtld_must_xmm_save)
may be updated by 2 processes at the same time since parent and
child share the same TLS.
Comment 4 H.J. Lu 2010-01-27 04:09:01 UTC
We can put wrapper of clone in nptl. If clone is
called with CLONE_VM, we mark ld.so TLS is shared.
Comment 5 Jakub Jelinek 2010-01-27 06:50:02 UTC
IMNSHO this is a gdb bug, there is no point hacking up something in this ld.so
case when many other things break equally horribly when using CLONE_VM without
cloning TLS - everything that uses __thread or other thread local area fields is
broken in that case.  While the kernel supports all flags for clone, glibc
supports only a limited subset of the combinations.
Comment 6 H.J. Lu 2010-01-27 13:02:43 UTC
CLONE_VM is used by many applications. What do they have to do
to clone TLS?
Comment 7 H.J. Lu 2010-01-27 13:55:20 UTC

Those applications don't use TLS and ld.so uses TLS behind their
back. Shouldn't ld.so use TLS only if libpthread is used?

Comment 10 Ulrich Drepper 2010-04-04 09:16:09 UTC
Not a glibc problem.
Comment 11 H.J. Lu 2012-01-25 22:42:24 UTC
nptl/tst-getpid2.c has

---
#define TEST_CLONE_FLAGS CLONE_VM
#include "tst-getpid1.c"
---

which calls clone with CLONE_VM and leads to nptl/tst-getpid2.c fails at
random with "illegal hardware instruction".

The GNU C Library
=================

The GNU C Library version 2.19 is now available.

The GNU C Library is used as *the* C library in the GNU systems
and most systems with the Linux kernel.

The GNU C Library is primarily designed to be a portable
and high performance C library.  It follows all relevant
standards including ISO C11 and POSIX.1-2008.  It is also
internationalized and has one of the most complete
internationalization interfaces known.

The GNU C Library webpage is at http://www.gnu.org/software/libc/

Packages for the 2.19 release may be downloaded from:
        http://ftpmirror.gnu.org/libc/
        http://ftp.gnu.org/gnu/libc/

The mirror list is at http://www.gnu.org/order/ftp.html

* Slovenian translations for glibc messages have been contributed by the
  Translation Project's Slovenian team of translators.

* The public headers no longer use __unused nor __block.  This change is to
  support compiling programs that are derived from BSD sources and use
  __unused internally, and to support compiling with Clang's -fblock
  extension which uses __block.

* CVE-2012-4412 The strcoll implementation caches indices and rules for
  large collation sequences to optimize multiple passes.  This cache
  computation may overflow for large collation sequences and may cause a
  stack or buffer overflow.  This is now fixed to use a slower algorithm
  which does not use a cache if there is an integer overflow.

* CVE-2012-4424 The strcoll implementation uses malloc to cache indices and
  rules for large collation sequences to optimize multiple passes and falls
  back to alloca if malloc fails, resulting in a possible stack overflow.
  The implementation now falls back to an uncached collation sequence lookup
  if malloc fails.

* CVE-2013-4788 The pointer guard used for pointer mangling was not
  initialized for static applications resulting in the security feature
  being disabled. The pointer guard is now correctly initialized to a
  random value for static applications. Existing static applications need
  to be recompiled to take advantage of the fix (bug 15754).

* CVE-2013-4237 The readdir_r function could write more than NAME_MAX bytes
  to the d_name member of struct dirent, or omit the terminating NUL
  character.  (Bugzilla #14699).

* CVE-2013-4332 The pvalloc, valloc, memalign, posix_memalign and
  aligned_alloc functions could allocate too few bytes or corrupt the
  heap when passed very large allocation size values (Bugzilla #15855,
  #15856, #15857).

* CVE-2013-4458 Stack overflow in getaddrinfo with large number of results
  for AF_INET6 has been fixed (Bugzilla #16072).

* New locales: ak_GH, anp_IN, ar_SS, cmn_TW, hak_TW, lzh_TW, nan_TW, pap_AW,
  pap_CW, quz_PE, the_NP.

* Substantially revised locales: gd_GB, ht_HT

* The LC_ADDRESS field was updated to support country_car for almost all
  supported locales.

* ISO 1427 definitions were updated.

* ISO 3166 definitions were updated.

* The localedef utility now supports --big-endian and --little-endian
  command-line options to generate locales for a different system from that
  for which the C library was built.

* Binary locale files now only depend on the endianness of the system for
  which they are generated and not on other properties of that system.  As a
  consequence, binary files generated with new localedef may be incompatible
  with old versions of the GNU C Library, and binary files generated with
  old localedef may be incompatible with this version of the GNU C Library,
  in the following circumstances:

  + Locale files may be incompatible on m68k systems.

  + Locale archive files (but not separate files for individual locales) may
    be incompatible on systems where plain "char" is signed.

* The configure option --disable-versioning has been removed.  Builds with
  --disable-versioning had not worked for several years.

* ISO 639 definitions were updated for Chiga (cgg) and Chinese (gan, hak, czh,
  cjy, lzh, cmn, mnp, cdo, czo, cpx, wuu, hsn, yue).

* SystemTap probes for malloc have been introduced.

* SystemTap probes for slow multiple precision fallback paths of
  transcendental functions have been introduced.

* Support for powerpc64le has been added.

* The soft-float powerpc port now supports e500 processors.

* Support for STT_GNU_IFUNC symbols added for ppc32/power4+ and ppc64.

* A new feature test macro _DEFAULT_SOURCE is available to enable the same
  set of header declarations that are enabled by default, even when other
  feature test macros or compiler options such as -std=c99 would otherwise
  disable some of those declarations.

* The _BSD_SOURCE feature test macro no longer enables BSD interfaces that
  conflict with POSIX.  The libbsd-compat library (which was a dummy library
  that did nothing) has also been removed.

* Preliminary documentation about Multi-Thread, Async-Signal and
  Async-Cancel Safety has been added.

    Don't run tst-getpid2 with LD_BIND_NOW=1
    
    Since _dl_x86_64_save_sse and _dl_x86_64_restore_sse are removed now,
    we don't need to run tst-getpid2 with LD_BIND_NOW=1.
    
    	[BZ #11214]
    	* sysdeps/unix/sysv/linux/Makefile (tst-getpid2-ENV): Removed.
