4863355ad5 Require GCC 4.6 or later to build glibc.
As discussed in the thread starting at
<https://sourceware.org/ml/libc-alpha/2014-10/msg00792.html>, and
continuing into November, this patch increases the minimum GCC version
for building glibc to 4.6 (there seemed to be no clear consensus for
4.7).  In particular, this allows us to use #pragma GCC diagnostic for
fine-grained warning control with -Werror (subject to establishing a
suitable policy for that use).  The documentation has a statement, as
requested, about the most recent GCC version tested for building
glibc, and I've updated <https://sourceware.org/glibc/wiki/Release> to
refer to updating that statement.  A NEWS entry is added for this
change, although previous such changes didn't get them.

Tested for x86_64 (testsuite, and that installed shared libraries are
unchanged by this patch).

	* configure.ac (libc_cv_compiler_ok): Require GCC 4.6 or later.
	* configure: Regenerated.
	* manual/install.texi (Tools for Compilation): Document a
	requirement of GCC 4.6 or later and that GCC 4.9 is the newest
	compiler verified to work.
	* INSTALL: Regenerated.

a2887bdb27 manual/llio.texi: Comment on write atomicity.
We add Linux-realted comments about the atomicity of
write with respect to file offsets. As of Linux 3.14
the file offset update is atomic. That means that
multiple threads calling the write syscall can not possibly
get the same file offset. Therefore the writes should
not overlap and data should not be lost as is required
by POSIX.

686554bff6 Remove redundant C locale settings.
Various glibc build / install / test code has C locale settings that
are redundant with LC_ALL=C.

LC_ALL takes precedence over LANG, so anywhere that sets LC_ALL=C
(explicitly, or through it being in the default environment for
running tests) does not need to set LANG=C.  LC_ALL=C also takes
precedence over LANGUAGE, since

2001-01-02  Ulrich Drepper  <drepper@redhat.com>

	* intl/dcigettext.c (guess_category_value): Rewrite so that LANGUAGE
	value is ignored if the selected locale is the C locale.
	* intl/tst-gettext.c: Set locale for above change.
	* intl/tst-translit.c: Likewise.

and so settings of LANGUAGE=C are also redundant when LC_ALL=C is
set.  One test also had LC_ALL=C in its -ENV setting, although it's
part of the default environment used for tests.

This patch removes the redundant settings.  It removes a suggestion in
install.texi of setting LANGUAGE=C LC_ALL=C for "make install"; the
Makefile.in target "install" already sets LC_ALL_C so there's no need
for the user to set it (and nor should there be any need for the user
to set it).

If some build machine tool used by "make install" uses a version of
libintl predating that 2001 change, and the user has LANGUAGE set, the
removal of LANGUAGE=C from the Makefile.in "install" rule could in
principle affect the user's installation.  However, I don't think we
need to be concerned about pre-2001 build tools.

Tested x86_64.

8540f6d2a7 Don't require test wrappers to preserve environment variables, use more consistent environment.
One wart in the original support for test wrappers for cross testing,
as noted in
<https://sourceware.org/ml/libc-alpha/2012-10/msg00722.html>, is the
requirement for test wrappers to pass a poorly-defined set of
environment variables from the build system to the system running the
glibc under test.  Although some variables are passed explicitly via
$(test-wrapper-env), including LD_* variables that simply can't be
passed implicitly because of the side effects they'd have on the build
system's dynamic linker, others are passed implicitly, including
variables such as GCONV_PATH and LOCPATH that could potentially affect
the build system's libc (so effectively relying on any such effects
not breaking the wrappers).  In addition, the code in
cross-test-ssh.sh for preserving environment variables is fragile (it
depends on how bash formats a list of exported variables, and could
well break for multi-line variable definitions where the contents
contain things looking like other variable definitions).

This patch moves to explicitly passing environment variables via
$(test-wrapper-env).  Makefile variables that previously used
$(test-wrapper) are split up into -before-env and -after-env parts
that can be passed separately to the various .sh files used in
testing, so those files can then insert environment settings between
the two parts.

The common default environment settings in make-test-out are made into
a separate makefile variable that can also be passed to scripts,
rather than many scripts duplicating those settings (for testing an
installed glibc, it is desirable to have the GCONV_PATH setting on
just one place, so just that one place needs to support it pointing to
an installed sysroot instead of the build tree).  The default settings
are included in the variables such as $(test-program-prefix), so that
if tests do not need any non-default settings they can continue to use
single variables rather than the split-up variables.

Although this patch cleans up LC_ALL=C settings (that being part of
the common defaults), various LANG=C and LANGUAGE=C settings remain.
Those are generally unnecessary and I propose a subsequent cleanup to
remove them.  LC_ALL takes precedence over LANG, and while LANGUAGE
takes precedence over LC_ALL, it only does so for settings other than
LC_ALL=C.  So LC_ALL=C on its own is sufficient to ensure the C
locale, and anything that gets LC_ALL=C does not need the other
settings.

While preparing this patch I noticed some tests with .sh files that
appeared to do nothing beyond what the generic makefile support for
tests can do (localedata/tst-wctype.sh - the makefiles support -ENV
variables and .input files - and localedata/tst-mbswcs.sh - just runs
five tests that could be run individually from the makefile).  So I
propose another subsequent cleanup to move those to using the generic
support instead of special .sh files.

d0f5b3f851 Increase minimum Linux kernel version to 2.6.32.
This patch increases the minimum Linux kernel version for glibc to
2.6.32, as discussed in the thread starting at
<https://sourceware.org/ml/libc-alpha/2014-01/msg00511.html>.

This patch just does the minimal change to arch_minimum_kernel
settings (and LIBC_LINUX_VERSION, which determines the minimum kernel
headers version, as it doesn't make sense for that to be older than
the minimum kernel that can be used at runtime).  Followups would be
expected to do, roughly and not necessarily precisely in this order:

* Remove __LINUX_KERNEL_VERSION checks in kernel-features.h files
  where those checks are always true / always false for kernels 2.6.32
  and above.

* Otherwise simplify/improve conditionals in those files (for example,
  where defining once in the main file then undefining in
  architecture-specific files makes things clearer than having lots of
  separate definitions of the same macro), possibly fixing in the
  process cases where a macro should optimally have been defined for a
  given architecture but wasn't.  (In the review in preparation for
  this version increase I checked what the right conditions should be
  for all macros in the main kernel-features.h whose definitions there
  would have been affected by the increase - but I only fixed that
  subset of the issues found where --enable-kernel=2.6.32 would have
  caused a kernel feature to be wrongly assumed to be present, not any
  cases where a feature is not assumed but could be assumed.)

* Remove conditionals on __ASSUME_* where they can now be taken to be
  always-true, and the definitions when the macros are only used in
  Linux-specific files.

* Split more architectures out of the main kernel-features.h (like
  ex-ports architectures), once various of the architecture
  conditionals there have been eliminated so the new
  architecture-specific files are no larger than actually necessary.

Tested x86_64.

d6fe5e582d Do not terminate default test runs on test failure.
This patch is an updated version of
<https://sourceware.org/ml/libc-alpha/2014-01/msg00198.html> and
<https://sourceware.org/ml/libc-alpha/2014-03/msg00180.html>.

Normal practice for software testsuites is that rather than
terminating immediately when a test fails, they continue running and
report at the end on how many tests passed or failed.

The principle behind the glibc testsuite stopping on failure was
probably that the expected state is no failures and so any failure
indicates a problem such as miscompilation.  In practice, while this
is fairly close to true for native testing on x86_64 and x86 (kernel
bugs and race conditions can still cause intermittent failures), it's
less likely to be the case on other platforms, and so people testing
glibc run the testsuite with "make -k" and then examine the logs to
determine whether the failures are what they expect to fail on that
platform, possibly with some automation for the comparison.

This patch switches the glibc testsuite to the normal convention of
not stopping on failure - unless you use stop-on-test-failure=y, in
which case it behaves essentially as it did before (and does not
generate overall test summaries on failure).  Instead, the summary
tests.sum may contain tests that FAILed.  At the end of the test run,
any FAIL or ERROR lines from tests.sum are printed, and then it exits
with error status if there were any such lines.  In addition, build
failures will also cause the test run to stop - this has the
justification that those *do* indicate serious problems that should be
promptly fixed and aren't generally hard to fix (but apart from that,
avoiding the build stopping on those failures seems harder).

Note that unlike the previous patches in this series, this *does*
require people with automation around testing glibc to change their
processes - either to start using tests.sum / xtests.sum to track
failures and compare them with expectations (with or without also
using "make -k" and examining "make" logs to identify build failures),
or else to use stop-on-test-failure=y and ignore the new tests.sum /
xtests.sum mechanism.  (If all you check is the exit status from "make
check", no changes are needed unless you want to avoid test runs

e6b6a85705 Don't include individual test ulps in libm-test-ulps.
As recently discussed
<https://sourceware.org/ml/libc-alpha/2014-02/msg00670.html>, it
doesn't seem particularly useful for libm-test-ulps files to contain
huge amounts of data on ulps for individual tests; just the global
maximum observed ulps for each function, together with the
verification of exceptions, errno and special results such as
infinities and NaNs for each test, suffices to verify that a
function's behavior on the given test inputs is within the expected
accuracy.  Removing this data reduces source tree churn caused by
updates to these files when libm tests are added, and reduces the
frequency with which testsuite additions actually need libm-test-ulps
changes at all.

Accordingly, this patch removes that data, so that individual tests
get checked against the global bounds for the given function and only
generate an error if those are exceeded.  Tested x86_64 (including
verifying that if an ulps value is artificially reduced, the tests do
indeed fail as they should and "make regen-ulps" generates the
expected changes).

f08e9a2629 Fix fallout from Joseph's untested Makeconfig change. 2014-02-28 13:00:27 -08:00
Joseph Myers
a5f891ac8d Consistently include Makeconfig after defining subdir.
In <https://sourceware.org/ml/libc-alpha/2014-01/msg00196.html> I
noted it was necessary to add includes of Makeconfig early in various
subdirectory makefiles for the tests-special variable settings added
by that patch to be conditional on configuration information.  No-one
commented on the general question there of whether Makeconfig should
always be included immediately after the definition of subdir.

This patch implements that early inclusion of Makeconfig in each
directory (which is a lot easier than consistent placement of includes
of Rules).  Includes are added if needed, or moved up if already
present.  Subdirectory "all:" targets are removed, since Makeconfig
provides one.

There is potential for further cleanups I haven't done.  Rules and
Makerules have code such as

ifneq   "$(findstring env,$(origin headers))" ""
headers :=
endif

to override to empty any value of various variables that came from the
environment.  I think there is a case for Makeconfig setting all the
subdirectory variables (other than subdir) to empty to ensure no
outside value is going to take effect if a subdirectory fails to
define a variable.  (A list of such variables, possibly out of date
and incomplete, is in manual/maint.texi.)  Rules and Makerules would
give errors if Makeconfig hadn't already been included, instead of
including it themselves.  The special code to override values coming
from the environment would then be obsolete and could be removed.

Tested x86_64, including that installed binaries are identical before
and after the patch.

c688b41960 Add _DEFAULT_SOURCE feature test macro.
This patch adds a feature test macro _DEFAULT_SOURCE to enable the
default set of header declarations.

The intention is: if _DEFAULT_SOURCE is not used there is no change to
the set of __USE_* macros glibc defines; if it's used on its own, and
without compiler options such as -std=c99 that define __STRICT_ANSI__,
again, there is no change; if it's used together with the macros it
approximately (i.e., apart from __USE_POSIX_IMPLICITLY) implies
(-D_BSD_SOURCE -D_SVID_SOURCE -D_POSIX_C_SOURCE=200809L), again, there
is no change.  Otherwise, it causes the relevant features to be
enabled, even if __STRICT_ANSI__, or another feature test macro, would
cause them to be disabled.

This macro deliberately bundles the POSIX.1-2008 (non-X/Open)
functionality with the BSD/SVID/"misc" functionality, rather than
defining a macro that gives just the latter, as many of the header
cleanups resulting from removing _BSD_SOURCE and _SVID_SOURCE support
are only possible when BSD/SVID/"misc" is always bundled with
POSIX.1-2008.

Tested x86_64.

ee0a148a56 Stop partial menu generation in INSTALL file
The commit d136c6dc resulted in menu text for the "Top" node being added
to the INSTALL file on regeneration.  As the full menu is not displayed
in the plain text file anyway, suppress the menu section completely to
avoid the additional text.

Also regenerate the INSTALL file to commit a small formatting change
introduced in the same commit.

b9ab448f98 Add error reporting (via errno) to getauxval().
[BZ 15846] As discussed in the recent thread on my $EXEC_ORIGIN patch
and in BZ 15846, getauxval() presently has no unambiguous way of
reporting an error condition.  It currently returns zero on error, but
this may also be a valid result for some auxv entries.  As there is no
clear invalid result for all current and future auxv entries, this patch
sets errno (following a suggestion in the BZ entry).

This version of the patch also adds documentation and tests for the
value-not-found conditions in getauxval().

3d7dc513b7 Mention FIPS 140-2 compliance and Sun RPC.
The Secure RPC implementation in glibc uses DES encryption
during authentication of the user. This use of DES means
that anyone using Sun RPC will likely not be compliant
with FIPS 140-2 which forbids the use of DES.

One solution to the compliance issue is to disable AUTH_DES
and AUTH_KERB, both use DES, when in FIPS compliance mode.
This is not a good idea because it disables all of the even
mildly secure methods of authentication allowing only plain
text methods.

Instead we leave AUTH_DES and AUTH_KERB enabled in FIPS
compliance mode and document the compliance issue in the
manual. FIPS allows this, that is to say that if you can't
fix it you must document the non-compliance.

This commit adds documentation to that effect in the
"DES encryption and password handling" section of the
manual.

e4608715e6 CVE-2013-2207, BZ #15755: Disable pt_chown.
The helper binary pt_chown tricked into granting access to another
user's pseudo-terminal.

Pre-conditions for the attack:

 * Attacker with local user account
 * Kernel with FUSE support
 * "user_allow_other" in /etc/fuse.conf
 * Victim with allocated slave in /dev/pts

Using the setuid installed pt_chown and a weak check on whether a file
descriptor is a tty, an attacker could fake a pty check using FUSE and
trick pt_chown to grant ownership of a pty descriptor that the current
user does not own.  It cannot access /dev/pts/ptmx however.

In most modern distributions pt_chown is not needed because devpts
is enabled by default. The fix for this CVE is to disable building
and using pt_chown by default. We still provide a configure option
to enable hte use of pt_chown but distributions do so at their own
risk.

60457d8a25 manual: delete nested @cartouche
Putting @cartouche inside of @smallexample does not work with HTML output
as the former produces a <table> while the latter produces a <pre>.  You
cannot nest a <table> in a <pre> as the contents are no longer formatted.

Since it's entirely unnecessary, and none of the other examples do this,
just drop the cartouche.

d9dc34cd56 Manual for platform-specific features and new __ppc_get_timebase inline.
[BZ #13743]
A new class of installed headers has been documented for low-level
platform-specific functionality.  PowerPC added the first instance with a
function to provide time base register access (__ppc_get_timebase).  This
is required for applications that measure time at high frequencies with
high precision that can't afford a syscall.
