Description Michael Kerrisk 2008-07-31 11:05:58 UTC

On overflow and underflow, scalb(), scalbln(), scalbn() correctly raises
exceptions.  But errno is not set.  For these errors errno should be set to ERANGE.

Background: 
On error, many glibc math functions both set errno and raise an exception
(fetestexcept(3)).  For example, the following  function all do this: acos(),
asin(), cosh(), sinh(), acosh(), asinh(), exp(), exp2(), ldexp(), log(),
log10(), log2().  However, there is much inconsistency.  Some functions raise an
exception, but don't set errno.  Some functions set errno for some errors, but
not others.  A few set errno, but don't raise an exception.  This series of bug
reports documents deviations from what I consider the ideal: all functions
should BOTH set errno AND raise an exception for all errors.

All of these reports relate to tests on glibc 2.8 (as provided by SUSE 11.0).

commit 8795b4a443a8f19d279e0c1bc99b73d1f5aec166
Author: Joseph Myers <joseph@codesourcery.com>
Date:   Mon Mar 31 14:57:53 2014 +0000

    Set errno for scalb errors (bug 6803, bug 6804).
    
    This patch fixes the default mode of scalb to set errno (bugs 6803 and
    6804).
    
    Previously, the _LIB_VERSION == _SVID_ mode would set errno but only
    in some relevant cases, and with various peculiarities (such as errno
    setting when an exact infinity or zero result arises with an argument
    to scalb being an infinity).  This patch leaves this mode
    bug-compatible, while making the default mode set errno in accordance
    with normal practice (so an exact infinity from an infinite argument
    is not an error, and nor is an exact zero result).  gen-libm-test.pl
    is taught new notation such as ERRNO_PLUS_OFLOW to facilitate writing
    the tests of errno setting for underflow / overflow in libm-test.inc.
    
    Note that bug 6803 also covers scalbn and scalbln, but this patch only
    addresses the scalb parts of that bug (along with the whole of bug
    6804).
    
    Tested x86_64 and x86.
    
    	[BZ #6803]
    	[BZ #6804]
    	* math/w_scalb.c (__scalb): For non-SVID mode, check result and
    	set errno as appropriate.
    	* math/w_scalbf.c (__scalbf): Likewise.
    	* math/w_scalbl.c (__scalbl): Likewise.
    	* math/gen-libm-test.pl (parse_args): Handle ERRNO_PLUS_OFLOW,
    	ERRNO_MINUS_OFLOW, ERRNO_PLUS_UFLOW and ERRNO_MINUS_UFLOW.
    	* math/libm-test.inc (scalb_test_data): Add errno expectations.
    	Add more NaN tests.

    [BZ #6803] Set errno for scalbln, scalbn
    
    Errno is not set and the testcases will fail.
    
    Now the scalbln-aliases are removed in i386/m68
    and the wrappers are used when calling the scalbln-functions.
    
    On ia64 only scalblnf has its own implementation.
    For scalbln and scalblnl the ieee754/dbl-64 and ieee754/ldbl-96 are used, thus
    the wrappers are needed, too.

    Generate en_GB.UTF-8 during testing
    
    This patch generates en_GB.UTF-8, which is used in
    tst-strcoll-overflow.  This solves the issue of failing xtests on
    s390/s390x.

17187, 17213, 17259, 17261, 17262, 17263, 17319, 17325, 17354.

* Reverted change of ABI data structures for s390 and s390x:
On s390 and s390x the size of struct ucontext and jmp_buf was increased in
2.19. This change is reverted in 2.20. The introduced 2.19 symbol versions
of getcontext, setjmp, _setjmp, __sigsetjmp, longjmp, _longjmp, siglongjmp
are preserved pointing straight to the same implementation as the old ones.
Given that, new callers will simply provide a too-big buffer to these
functions. Any applications/libraries out there that embed jmp_buf or
ucontext_t in an ABI-relevant data structure that have already been rebuilt
against 2.19 headers will have to rebuilt again. This is necessary in any
case to revert the breakage in their ABI caused by the glibc change.

* Support for file description locks is added to systems running the
Linux kernel. The standard file locking interfaces are extended to
operate on file descriptions, not file descriptors, via the use of
F_OFD_GETLK, F_OFD_SETLK, and F_OFD_SETLKW. File description locks
are associated with an open file instead of a process.

* Optimized strchr implementation for AArch64. Contributed by ARM Ltd.

* The minimum Linux kernel version that this version of the GNU C Library
can be used with is 2.6.32.

* Running the testsuite no longer terminates as soon as a test fails.
Instead, a file tests.sum (xtests.sum from "make xcheck") is generated,
with PASS or FAIL lines for individual tests. A summary of the results is
printed, including a list of failing lists, and "make check" exits with
error status if there were any unexpected failures. "make check
stop-on-test-failure=y" may be used to keep the old behavior.

* The am33 port, which had not worked for several years, has been removed
from ports.

* The _BSD_SOURCE and _SVID_SOURCE feature test macros are no longer
supported; they now act the same as _DEFAULT_SOURCE (but generate a
warning). Except for cases where _BSD_SOURCE enabled BSD interfaces that
conflicted with POSIX (support for which was removed in 2.19), the
interfaces those macros enabled remain available when compiling with
_GNU_SOURCE defined, with _DEFAULT_SOURCE defined, or without any feature
test macros defined.

* Optimized strcmp implementation for ARMv7. Contributed by ARM Ltd.

* Added support for TX lock elision of pthread mutexes on s390 and s390x.
This may improve lock scaling of existing programs on TX capable systems.
The lock elision code is only built with --enable-lock-elision=yes and
then requires a GCC version supporting the TX builtins. With lock elision
default mutexes are elided via __builtin_tbegin, if the cpu supports
transactions. By default lock elision is not enabled and the elision code
is not built.

* CVE-2014-4043 The posix_spawn_file_actions_addopen implementation did not
copy the path argument. This allowed programs to cause posix_spawn to
deference a dangling pointer, or use an unexpected pathname argument if
the string was modified after the posix_spawn_file_actions_addopen
invocation.

* All supported architectures now use the main glibc sysdeps directory
instead of some being in a separate "ports" directory (which was
distributed separately before glibc 2.17).

* The NPTL implementation of POSIX pthreads is no longer an "add-on".
On configurations that support it (all Linux configurations), it's now
used regardless of the --enable-add-ons switch to configure. It is no
longer possible to build such configurations without pthreads support.

* Locale names, including those obtained from environment variables (LANG
and the LC_* variables), are more tightly checked for proper syntax.
setlocale will now fail (with EINVAL) for locale names that are overly
long, contain slashes without starting with a slash, or contain ".." path
components. (CVE-2014-0475) Previously, some valid locale names were
silently replaced with the "C" locale when running in AT_SECURE mode
(e.g., in a SUID program). This is no longer necessary because of the
additional checks.

* On x86-64, the dynamic linker's lazy-binding support is now compatible
with application code using Intel MPX instructions. (With all previous
versions, the MPX register state could be clobbered when making calls
into or out of a shared library.) Note that while the new dynamic
linker is compatible with all known x86 hardware whether or not it
supports Intel MPX, some x86 instruction-set emulators might fail to
handle the new instruction encodings. This is known to affect Valgrind
versions up through 3.9 (but will be fixed in the forthcoming 3.10
release), and might affect other tools that do instruction emulation.

* Support for loadable gconv transliteration modules has been removed.
The support for transliteration modules has been non-functional for
over a decade, and the removal is prompted by security defects. The
normal gconv conversion modules are still supported. Transliteration
with //TRANSLIT is still possible, and the //IGNORE specifier
continues to be supported. (CVE-2014-5119)

* Decoding a crafted input sequence in the character sets IBM933, IBM935,
IBM937, IBM939, IBM1364 could result in an out-of-bounds array read,
resulting a denial-of-service security vulnerability in applications which
use functions related to iconv. (CVE-2014-6040)

commit da2f4f2dd5c07e1949f81a5ee23f880e891e3a82
Author: Joseph Myers <joseph@codesourcery.com>
Date:   Wed Sep 16 21:11:00 2015 +0000

    Make scalbn set errno (bug 6803).
    
    As noted in bug 6803, scalbn fails to set errno on overflow and
    underflow.  This patch fixes this by making scalbn an alias of ldexp,
    which has exactly the same semantics (for floating-point types with
    radix 2) and already has wrappers that deal with setting errno,
    instead of an alias of the internal __scalbn (which ldexp calls).
    
    Notes:
    
    * Where compat symbols were defined for scalbn functions, I didn't
      change what they point to (to keep the patch minimal), so such
      compat symbols continue to go directly to the non-errno-setting
      functions.
    
    * Mike, I didn't do anything with the IA64 versions of these
      functions, where I think both the ldexp and scalbn functions already
      deal with setting errno.  As a cleanup (not needed to fix this bug)
      however you might want to make those functions into aliases for
      IA64; there is no need for them to be separate function
      implementations at all.
    
    * This concludes the fix for bug 6803 since the scalb and scalbln
      cases of that bug were fixed some time ago.
    
    Tested for x86_64, x86, mips64 and powerpc.
    
    	[BZ #6803]

commit 8fed86556b7e162d2926f0ba6a573ed193ff882f
Author: Joseph Myers <joseph@codesourcery.com>
Date:   Thu Nov 5 17:00:31 2015 +0000

    Don't redirect ldexp to scalbn in bits/math-finite.h (bug 19209).
    
    bits/math-finite.h maps ldexp functions to corresponding scalbn
    functions.  This is (a) a namespace bug for C90, which has ldexp but
    not scalbn, and (b) in any case useless, since the ldexp and scalbn
    functions have identical semantics (for floating-point types with
    radix 2), and since the fix for bug 6803 are actually aliases
    (presumably the mapping was based around the old bug of scalbn not
    setting errno).  This patch removes the bogus redirections.
    
    Tested for x86_64 and x86.
    
    	[BZ #19209]
    	* math/bits/math-finite.h (ldexp): Remove declaration.
    	(ldexpf): Likewise.
    	(ldexpl): Likewise.

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

The GNU C Library version 2.23 is now available.

The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the 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 2.23 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

NEWS for version 2.23
=====================

* Unicode 8.0.0 Support: Character encoding, character type info, and
  transliteration tables are all updated to Unicode 8.0.0, using new
  and/or improved generator scripts contributed by Mike FABIAN (Red Hat).
  These updates cause user visible changes, such as the fixes for bugs
  89, 16061, and 18568.

* sched_setaffinity, pthread_setaffinity_np no longer attempt to guess the
  kernel-internal CPU set size.  This means that requests that change the
  CPU affinity which failed before (for example, an all-ones CPU mask) will
  now succeed.  Applications that need to determine the effective CPU
  affinities need to call sched_getaffinity or pthread_getaffinity_np after
  setting it because the kernel can adjust it (and the previous size check
  would not detect this in the majority of cases).

* The fts.h header can now be used with -D_FILE_OFFSET_BITS=64.  With LFS
  the following new symbols are used: fts64_children, fts64_close,
  fts64_open, fts64_read and fts64_set.

* getaddrinfo now detects certain invalid responses on an internal netlink
  socket.  If such responses are received, an affected process will
  terminate with an error message of "Unexpected error <number> on netlink
  descriptor <number>" or "Unexpected netlink response of size <number> on
  descriptor <number>".  The most likely cause for these errors is a
  multi-threaded application which erroneously closes and reuses the netlink
  file descriptor while it is used by getaddrinfo.

* A defect in the malloc implementation, present since glibc 2.15 (2012) or
  glibc 2.10 via --enable-experimental-malloc (2009), could result in the
  unnecessary serialization of memory allocation requests across threads.
  The defect is now corrected.  Users should see a substantial increase in
  the concurent throughput of allocation requests for applications which
  trigger this bug.  Affected applications typically create create and
  destroy threads frequently.  (Bug 19048 was reported and analyzed by
  Ericsson.)

* There is now a --disable-timezone-tools configure option for disabling the
  building and installing of the timezone related utilities (zic, zdump, and
  tzselect).  This is useful for people who build the timezone data and code
  independent of the GNU C Library.

* The obsolete header <regexp.h> has been removed.  Programs that require
  this header must be updated to use <regex.h> instead.

* The obsolete functions bdflush, create_module, get_kernel_syms,
  query_module and uselib are no longer available to newly linked binaries;
  the header <sys/kdaemon.h> has been removed.  These functions and header
  were specific to systems using the Linux kernel and could not usefully be
  used with the GNU C Library on systems with version 2.6 or later of the
  Linux kernel.

* Optimized string, wcsmbs and memory functions for IBM z13.
  Implemented by Stefan Liebler.

* Newly linked programs that define a variable called signgam will no longer
  have it set by the lgamma, lgammaf and lgammal functions.  Programs that
  require signgam to be set by those functions must ensure that they use the
  variable provided by the GNU C Library and declared in <math.h>, without
  defining their own copy.

* The minimum GCC version that can be used to build this version of the GNU
  C Library is GCC 4.7.  Older GCC versions, and non-GNU compilers, can
  still be used to compile programs using the GNU C Library.

Security related changes:

* An out-of-bounds value in a broken-out struct tm argument to strftime no
  longer causes a crash.  Reported by Adam Nielsen.  (CVE-2015-8776)

* The LD_POINTER_GUARD environment variable can no longer be used to disable
  the pointer guard feature.  It is always enabled.  Previously,
  LD_POINTER_GUARD could be used to disable security hardening in binaries
  running in privileged AT_SECURE mode.  Reported by Hector Marco-Gisbert.
  (CVE-2015-8777)

* An integer overflow in hcreate and hcreate_r could lead to an
  out-of-bounds memory access.  Reported by Szabolcs Nagy.  (CVE-2015-8778)

* The catopen function no longer has unbounded stack usage.  Reported by
  Max.  (CVE-2015-8779)

* The nan, nanf and nanl functions no longer have unbounded stack usage
  depending on the length of the string passed as an argument to the
  functions.  Reported by Joseph Myers.  (CVE-2014-9761)

* A stack-based buffer overflow was found in libresolv when invoked from
  libnss_dns, allowing specially crafted DNS responses to seize control
  of execution flow in the DNS client.  The buffer overflow occurs in
  the functions send_dg (send datagram) and send_vc (send TCP) for the
  NSS module libnss_dns.so.2 when calling getaddrinfo with AF_UNSPEC
  family.  The use of AF_UNSPEC triggers the low-level resolver code to
  send out two parallel queries for A and AAAA.  A mismanagement of the
  buffers used for those queries could result in the response of a query
  writing beyond the alloca allocated buffer created by
  _nss_dns_gethostbyname4_r.  Buffer management is simplified to remove
  the overflow.  Thanks to the Google Security Team and Red Hat for
  reporting the security impact of this issue, and Robert Holiday of
  Ciena for reporting the related bug 18665. (CVE-2015-7547)

      Add a new benchmark for isinf/isnan/isnormal/isfinite/fpclassify. The test uses 2 arrays with 1024 doubles, one with 99% finite FP numbers (10% zeroes, 10% negative) and 1% inf/NaN, the other with 50% inf, and 50% Nan.

      Use the GCC builtin functions for the non-inlined signbit implementations.
