4a39c34c4f Change most internal uses of __gettimeofday to __clock_gettime.
Since gettimeofday will shortly be implemented in terms of
clock_gettime on all platforms, internal code should use clock_gettime
directly; in addition to removing a layer of indirection, this will
allow us to remove the PLT-bypass gunk for gettimeofday.  (We can't
quite do that yet, but it'll be coming later in this patch series.)
In many cases, the changed code does fewer conversions.

The changed code always assumes __clock_gettime (CLOCK_REALTIME)
cannot fail.  Most of the call sites were assuming gettimeofday could
not fail, but a few places were checking for errors.  POSIX says
clock_gettime can only fail if the clock constant is invalid or
unsupported, and CLOCK_REALTIME is the one and only clock constant
that's required to be supported.  For consistency I grepped the entire
source tree for any other places that checked for errors from
__clock_gettime (CLOCK_REALTIME), found one, and changed it too.

(For the record, POSIX also says gettimeofday can never fail.)

(It would be nice if we could declare that GNU systems will always
support CLOCK_MONOTONIC as well as CLOCK_REALTIME; there are several
places where we are using CLOCK_REALTIME where _MONOTONIC would be
more appropriate, and/or trying to use _MONOTONIC and then falling
back to _REALTIME.  But the Hurd doesn't support CLOCK_MONOTONIC yet,
and it looks like adding it would involve substantial changes to
gnumach's internals and API.  Oh well.)

A few Hurd-specific files were changed to use __host_get_time instead
of __clock_gettime, as this seemed tidier.  We also assume this cannot
fail.  Skimming the code in gnumach leads me to believe the only way
it could fail is if __mach_host_self also failed, and our
Hurd-specific code consistently assumes that can't happen, so I'm
going with that.

With the exception of support/support_test_main.c, test cases are not
modified, mainly because I didn't want to have to figure out which
test cases were testing gettimeofday specifically.

The definition of GETTIME in sysdeps/generic/memusage.h had a typo and
was not reading tv_sec at all.  I fixed this.  It appears nobody has been
generating malloc traces on a machine that doesn't have a superseding
definition.

There are a whole bunch of places where the code could be simplified
by factoring out timespec subtraction and/or comparison logic, but I
want to keep this patch as mechanical as possible.

Checked on x86_64-linux-gnu, i686-linux-gnu, powerpc64le-linux-gnu,
powerpc64-linux-gnu, powerpc-linux-gnu, and aarch64-linux-gnu.

5d245b5f8d inet/net-internal.h: Fix uninitalised clntudp_call() variable
The total_deadline variable inside the clntudp_call() function inside
sunrpc/clnt_udp.c can cause uninitalised variable warnings when building
with GCC 8.3 or 9.2 on a platform with a 64-bit tv_nsec on a 32-bit
architecture.  To fix the warning let's use the DIAG_* macros to hide the
warning.

A GCC bug case has also been submitted:

899478c2bf inet/tst-if_index-long: New test case for CVE-2018-19591 [BZ #23927] 2018-12-06 15:39:50 +01:00

841785bad1 manual: Revise crypt.texi.
This is a major rewrite of the description of 'crypt', 'getentropy',
and 'getrandom'.

A few highlights of the content changes:

 - Throughout the manual, public headers, and user-visible messages,
   I replaced the term "password" with "passphrase", the term
   "password database" with "user database", and the term
   "encrypt(ion)" with "(one-way) hashing" whenever it was applied to
   passphrases.  I didn't bother making this change in internal code
   or tests.  The use of the term "password" in ruserpass.c survives,
   because that refers to a keyword in netrc files, but it is adjusted
   to make this clearer.

   There is a note in crypt.texi explaining that they were
   traditionally called passwords but single words are not good enough
   anymore, and a note in users.texi explaining that actual passphrase
   hashes are found in a "shadow" database nowadays.

 - There is a new short introduction to the "Cryptographic Functions"
   section, explaining how we do not intend to be a general-purpose
   cryptography library, and cautioning that there _are_, or have
   been, legal restrictions on the use of cryptography in many
   countries, without getting into any kind of detail that we can't
   promise to keep up to date.

 - I added more detail about what a "one-way function" is, and why
   they are used to obscure passphrases for storage.  I removed the
   paragraph saying that systems not connected to a network need no
   user authentication, because that's a pretty rare situation
   nowadays.  (It still says "sometimes it is necessary" to
   authenticate the user, though.)

 - I added documentation for all of the hash functions that glibc
   actually supports, but not for the additional hash functions
   supported by libxcrypt.  If we're going to keep this manual section
   around after the transition is more advanced, it would probably
   make sense to add them then.

 - There is much more detailed discussion of how to generate a salt,
   and the failure behavior for crypt is documented.  (Returning an
   invalid hash on failure is what libxcrypt does; Solar Designer's
   notes say that this was done "for compatibility with old programs
   that assume crypt can never fail".)

 - As far as I can tell, the header 'crypt.h' is entirely a GNU
   invention, and never existed on any other Unix lineage.  The
   function 'crypt', however, was in Issue 1 of the SVID and is now
   in the XSI component of POSIX.  I tried to make all of the
   @standards annotations consistent with this, but I'm not sure I got
   them perfectly right.

 - The genpass.c example has been improved to use getentropy instead
   of the current time to generate the salt, and to use a SHA-256 hash
   instead of MD5. It uses more random bytes than is strictly
   necessary because I didn't want to complicate the code with proper
   base64 encoding.

 - The testpass.c example has three hardwired hashes now, to
   demonstrate that different one-way functions produce different
   hashes for the same input.  It also demonstrates how DES hashing
   only pays attention to the first eight characters of the input.

 - There is new text explaining in more detail how a CSPRNG differs
   from a regular random number generator, and how
   getentropy/getrandom are not exactly a CSPRNG.  I tried not to make
   specific falsifiable claims here.  I also tried to make the
   blocking/cancellation/error behavior of both getentropy and
   getrandom clearer.

c88ffc239e NSS: Replace exported NSS lookup functions with stubs [BZ #21962]
Commit 384ca55174 from 2007 added this to
nss/XXX-lookup.c:

+#ifndef NO_COMPAT
+int
+internal_function attribute_compat_text_section
+DB_COMPAT_FCT (service_user **ni, const char *fct_name, void **fctp)
+{
+  return DB_LOOKUP_FCT (ni, fct_name, NULL, fctp);
+}
+#endif

That is, it adds a pseudo-compat function with an internal_function
attribute.  The function it was supposed to replace did not have the
attribute:

 extern int DB_LOOKUP_FCT (service_user **ni, const char *fct_name,
-			  void **fctp) internal_function;
+			  const char *fct2_name, void **fctp)
+  internal_function;

This changed the calling convention on i386 for the following
functions in the public ABI:

  __nss_passwd_lookup
  __nss_group_lookup
  __nss_hosts_lookup

This commit replaces the functions with always-failing stubs,
with true compat symbols.  Due to a happy accident, the calling
convention of the stub is identical for the internal_function
and non-internal_function case on i386.

In addition, this commit auto-generates the __nss_*_lookup2
function declarations as part of <nsswitch.h>.

f87cc2bfba __inet6_scopeid_pton: Remove attribute_hidden, internal_function
The hidden attribute was overridden by libc_hidden_proto on GNU/Linux.
It is incorrect because the function is used from nscd.

internal_function is not supposed to be used across DSO boundaries,
so this commit removes it (again, due to the use in nscd).

d9fee042e2 Consistently use uintN_t not u_intN_t everywhere.
This patch changes the remaining uses of the old nonstandard u_intN_t
types in glibc to use the C99 uintN_t instead, except for the
definitions of those typedefs and the tests of them in the c++-types
test.  This follows the previous such fix for libm, and being
consistent in using uintN_t makes sense as a global cleanup.

Tested for x86_64, and with build-many-glibcs.py.

e6b4e2de6d resolv: Call _res_hconf_init from __res_vinit
Many callers of __res_maybe_init also call _res_hconf_init.
Additional calls to the latter do not hurt because the function
does its work only once.  (/etc/hosts.conf is not reloaded or
even checked for changes.)  This means that we can simplify the
code by calling _res_hconf_init directly from __res_vinit.

a992f506ff Remove __need macros from signal.h.
The types affected are __sig_atomic_t, sig_atomic_t, __sigset_t,
sigset_t, sigval_t, sigevent_t, and siginfo_t. __sig_atomic_t is a
scalar, so it's now directly available from bits/types.h.  The others
get bits/types/ headers.

Side effects include: There have been small changes to which
non-signal headers expose which subset of the signal-related types.
A couple of architectures' nested siginfo_t fields had to be renamed
to prevent undesired macro expansion.  Internal code that wants to
manipulate signal masks must now include <sigsetops.h> (which is not
installed) and should be aware that __sigaddset, __sigandset,
__sigdelset, __sigemptyset, and __sigorset no longer return a value
(unlike the public API).  Relatedly, the public signal.h no longer

longer has a system-specific definition -- in the cases where it
matters, it didn't work anyway.

New Linux architectures should create bits/siginfo-arch.h and/or
bits/siginfo-consts-arch.h to customize their siginfo_t, rather than
duplicating everything in bits/siginfo.h (which no longer exists).
Add new __SI_* macros if necessary.  Ports to other operating systems
are strongly encouraged to generalize this scheme further.

7c3018f9e4 Suppress internal declarations for most of the testsuite.
This patch adds a new build module called 'testsuite'.
IS_IN (testsuite) implies _ISOMAC, as do IS_IN_build and __cplusplus
(which means several ad-hoc tests for __cplusplus can go away).
libc-symbols.h now suppresses almost all of *itself* when _ISOMAC is
defined; in particular, _ISOMAC mode does not get config.h
automatically anymore.

There are still quite a few tests that need to see internal gunk of
one variety or another.  For them, we now have 'tests-internal' and
'test-internal-extras'; files in this category will still be compiled
with MODULE_NAME=nonlib, and everything proceeds as it always has.
The bulk of this patch is moving tests from 'tests' to
'tests-internal'.  There is also 'tests-static-internal', which has
the same effect on files in 'tests-static', and 'modules-names-tests',
which has the *inverse* effect on files in 'modules-names' (it's
inverted because most of the things in modules-names are *not* tests).
For both of these, the file must appear in *both* the new variable and
the old one.

There is also now a special case for when libc-symbols.h is included
without MODULE_NAME being defined at all.  (This happens during the
creation of libc-modules.h, and also when preprocessing Versions
files.)  When this happens, IS_IN is set to be always false and
_ISOMAC is *not* defined, which was the status quo, but now it's
explicit.

The remaining changes to C source files in this patch seemed likely to
cause problems in the absence of the main change.  They should be
relatively self-explanatory.  In a few cases I duplicated a definition
from an internal header rather than move the test to tests-internal;
this was a judgement call each time and I'm happy to change those
however reviewers feel is more appropriate.

	* Makerules: New subdir configuration variables 'tests-internal'
	and 'test-internal-extras'.  Test files in these categories will
	still be compiled with MODULE_NAME=nonlib.  Test files in the
	existing categories (tests, xtests, test-srcs, test-extras) are
	now compiled with MODULE_NAME=testsuite.
	New subdir configuration variable 'modules-names-tests'.  Files
	which are in both 'modules-names' and 'modules-names-tests' will
	be compiled with MODULE_NAME=testsuite instead of
	MODULE_NAME=extramodules.
	(gen-as-const-headers): Move to tests-internal.
	(do-tests-clean, common-mostlyclean): Support tests-internal.
	* Makeconfig (built-modules): Add testsuite.
	* Makefile: Change libof-check-installed-headers-c and
	libof-check-installed-headers-cxx to 'testsuite'.
	* Rules: Likewise.  Support tests-internal.
	* benchtests/strcoll-inputs/filelist#en_US.UTF-8:
	Remove extra-modules.mk.

	* config.h.in: Don't check for __OPTIMIZE__ or __FAST_MATH__ here.
	* include/libc-symbols.h: Move definitions of _GNU_SOURCE,
	PASTE_NAME, PASTE_NAME1, IN_MODULE, IS_IN, and IS_IN_LIB to the
	very top of the file and rationalize their order.
	If MODULE_NAME is not defined at all, define IS_IN to always be
	false, and don't define _ISOMAC.
	If any of IS_IN (testsuite), IS_IN_build, or __cplusplus are
	true, define _ISOMAC and suppress everything else in this file,
	starting with the inclusion of config.h.
	Do check for inappropriate definitions of __OPTIMIZE__ and
	__FAST_MATH__ here, but only if _ISOMAC is not defined.
        Correct some out-of-date commentary.

	* include/math.h: If _ISOMAC is defined, undefine NO_LONG_DOUBLE
	and _Mlong_double_ before including math.h.
	* include/string.h: If _ISOMAC is defined, don't expose
	_STRING_ARCH_unaligned. Move a comment to a more appropriate
	location.

	* include/errno.h, include/stdio.h, include/stdlib.h, include/string.h
	* include/time.h, include/unistd.h, include/wchar.h: No need to
	check __cplusplus nor use __BEGIN_DECLS/__END_DECLS.

	(__m81_defun): Use __NTHNL to avoid errors with GCC 6.

176804300b Fix network headers stdint.h namespace (bug 21455).
conform/ namespace tests of arpa/inet.h, netdb.h and netinet/in.h fail
for UNIX98 and XPG42 because of inclusion of stdint.h, which defines
macros not permitted in those headers for those standards.  UNIX98
allows them to include inttypes.h, but (predating C99) has restricted
inttypes.h contents (not yet tested in the conform/ tests) not
including those macros; XPG4.2 has no such permission and no
inttypes.h / stdint.h at all.

This patch rearranges the headers to avoid this issue.  intN_t
definitions move to bits/stdint-intn.h, and uintN_t definitions to
bits/stdint-uintn.h.  (These are not bits/types/ headers because they
each define four types.  They are separate rather than just a single
header because sys/types.h defines intN_t but u_intN_t rather than
uintN_t - and while sys/types.h could define uintN_t because of the
POSIX reservation of *_t, existing practice there is largely to
condition types on appropriate feature test macros, and indeed there
is at least one open bug report (14553) about a type that's not
so-conditioned, so maybe types there should actually have conditions
added where appropriate.)  The affected network headers are then made
to include bits/stdint-uintn.h instead of stdint.h.  This allows six
XFAILs to be removed.

This doesn't do anything about inttypes.h defining more than it should
for UNIX98, but we don't have conformtest expectations for that case
at present (and my inclination is that a fix for that should be as
local as possible - affecting only inttypes.h, not stdint.h, only for
the case of __USE_UNIX98 && !__USE_ISOC99).

Tested for x86_64.

ae65d4f3c3 Remove the str(n)dup inlines from string/bits/string2.h. Although inlining
calls with constant strings shows a small (~10%) performance gain, strdup is
typically used in error reporting code, so not performance critical.
Remove the now unused __need_malloc_and_calloc related defines from stdlib.h.

Rename existing uses of str(n)dup to __str(n)dup so it no longer needs to be
redirected to a builtin.  Also building GLIBC with -Os now no longer shows
localplt or linkname space failures (partial fix for BZ #15105 and BZ #19463).

6a1cefac19 Make endian-conversion macros always return correct types (bug 16458).
Bug 16458 reports that the endian-conversion macros in <endian.h> and
<netinet/in.h>, in the case where no endian conversion is needed, just
return their arguments without converting to the expected return type,
so failing to act as expected for a macro version of a function.  (The
<netinet/in.h> macros, in particular, are described with prototypes in
POSIX so should act like correspondingly prototyped functions.)

Where previously this was a fairly obscure issue, it now results in
glibc build with GCC mainline breaking for big-endian systems:

nss_hesiod/hesiod-service.c: In function '_nss_hesiod_getservbyport_r':
nss_hesiod/hesiod-service.c:142:39: error: '%d' directive output may be truncated writing between 1 and 11 bytes into a region of size 6 [-Werror=format-truncation=]
   snprintf (portstr, sizeof portstr, "%d", ntohs (port));
                                       ^~
nss_hesiod/hesiod-service.c:142:38: note: using the range [1, -2147483648] for directive argument
   snprintf (portstr, sizeof portstr, "%d", ntohs (port));
                                      ^~~~
nss_hesiod/hesiod-service.c:142:3: note: format output between 2 and 12 bytes into a destination of size 6
   snprintf (portstr, sizeof portstr, "%d", ntohs (port));
   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The port argument is passed as int to this function, so when ntohs
does not convert the compiler cannot tell that the result is within
the range of uint16_t.  (I don't know if in fact it's possible for
out-of-range values to reach this function and so get truncated as
strings without this patch or as integers with it.)

This patch arranges for these macros to use identity functions to
ensure appropriate conversions while having warnings for implicit
conversions of function arguments that might not occur with a cast.

Tested for x86_64 and x86; with build-many-glibcs.py with GCC 6; and
with build-many-glibcs.py with GCC mainline for powerpc to test the
build fix.

f2bea4da2e Installed-header hygiene (BZ#20366): conditionally defined structures.
Several network-related structures are defined conditionally under
__USE_MISC, but unconditionally used by other headers.  The path of
least resistance is usually to condition the uses on __USE_MISC as
well.

	* sysdeps/mach/hurd/net/if_ppp.h
	* sysdeps/unix/sysv/linux/net/if_ppp.h:
        Only define struct ifpppstatsreq and struct ifpppcstatsreq
        if __USE_MISC is defined, to ensure struct ifreq is declared.

	* inet/netinet/ether.h: Condition all function prototypes
        on __USE_MISC, to ensure struct ether_addr is declared.

sys/socket.h defines struct osockaddr only under __USE_MISC, whereas
protocols/talkd.h requires it unconditionally.  Here it doesn't make
sense to condition the entire body of protocols/talkd.h on __USE_MISC.
Rather than complicate sys/socket.h with a __need macro or duplicate
the definition, I am introducing a new concept: tiny headers named
bits/types/TYPE.h that define TYPE and nothing else.  This can, I hope,
ultimately replace *all* the __need macros.  The guard macro for such
headers will be __TYPE_defined, just in case application or third-party
library code is looking at them.

	* socket/bits/types/struct_osockaddr.h: New header.
	* include/bits/types/struct_osockaddr.h: New wrapper.
	* socket/Makefile: Install the new header.
	* socket/sys/socket.h,  inet/protocols/talkd.h:
	Refer to bits/types/struct_osockaddr.h for the definition of
	struct osockaddr.

11160cb76f Installed-header hygiene (BZ#20366): obsolete BSD u_* types.
The types u_char, u_short, u_int, u_long, ushort, uint, ulong, u_int8_t,
u_int16_t, u_int32_t, u_int64_t, quad_t, and u_quad_t are BSDisms that
have never been standardized.  While glibc should continue to *provide*
these types for compatibility's sake, its public headers should not
use them.

The meat of this change was mechanically generated by the following
shell command:

    perl -pi~ -e '
        s/\b(__)?u_char\b/unsigned char/g;
        s/\b(__)?u_?short\b/unsigned short/g;
        s/\b(__)?u_?int\b/unsigned int/g;
        s/\b(__)?u_?long\b/unsigned long/g;
        s/\b(__)?u_int8_t\b/uint8_t/g;
        s/\b(__)?u_int16_t\b/uint16_t/g;
        s/\b(__)?u_int32_t\b/uint32_t/g;
        s/\b(__)?u_int64_t\b/uint64_t/g;
        s/\b(__)?u_quad_t\b/uint64_t/g;
        s/\b(__)?quad_t\b/uint64_t/g;
    ' $(grep -lE -e '\<((__)?(quad_t|u(short|int|long|_(char|short|int([0-9]+_t)?|long|quad_t))))\>' \
        $(grep -LE '\<(_(SYS|BITS)_TYPES_H|rpc/(rpc|rpc_msg|types|xdr)\.h)\>' \
          $(find . \( -false $(sed 's/^/-o -name /' all-installed-headers) \
                   \) -printf '%P\n' | sort -u)))

where 'all-installed-headers' was a list of the basenames of all installed
header files, manually extracted from the Makefiles.  Non-installed
wrapper headers in include/ are also adjusted, for consistency.
I then manually fixed up indentation and line-wrapping.

sys/types.h and bits/types.h are excluded because they must continue
to define the u_* types (under __USE_MISC) for compatibility with
applications.  They do not use these types themselves.

All headers that (transitively) include rpc/types.h are also excluded,
for three reasons.  First, the u_* types are defined by rpc/types.h,
unconditionally (not just under __USE_MISC) so they are logically part
of the SunRPC API.  Second, many of those headers appear to be
machine-generated.  Third, it's my understanding that we are getting
rid of as much of SunRPC as possible in the near future.

(The one file under sunrpc/ that's touched, sunrpc/rpc/rpc_des.h, does
*not* include rpc/types.h.  This may itself be a bug.)

After changing from u_intNN_t to uintNN_t, a number of headers now
need to include stdint.h to pick up those types.  It might be more
hygenic, namespace-wise, to use __uintNN_t instead, but none of these
headers are bound by ISO or POSIX to do so, and it's unlikely that
anyone using them will be bothered.  (The two files that were using
__-prefixed versions of the u_types, sysdeps/mach/hurd/net/route.h and
sysdeps/unix/sysv/linux/net/route.h, both already also contained uses of
the unprefixed versions.)

Some of these files directly included features.h and/or sys/cdefs.h,
which I removed, as the style generally seems to be to let sys/types.h
do that for us.  (This does not change the set of definitions exposed
by any header; sys/types.h unconditionally includes both features.h
and sys/cdefs.h.)

One file included asm/types.h unnecessarily.

cb765808fb Installed-header hygiene (BZ#20366): Simple self-contained fixes.
Some headers did not include all of their prerequisite headers.

	* rpcsvc/nislib.h: Include rpcsvc/nis.h.
	* sysdeps/unix/sysv/linux/netrose/rose.h:
	Include sys/socket.h and netax25/ax25.h.

<endian.h> only defines BYTE_ORDER, BIG_ENDIAN, LITTLE_ENDIAN,
etc. under __USE_MISC; glibc's headers should use __BYTE_ORDER,
__BIG_ENDIAN, __LITTLE_ENDIAN, etc. instead.

	* inet/netinet/icmp6.h, inet/netinet/ip6.h
	* resolv/arpa/nameser_compat.h:
	Use __BYTE_ORDER etc. instead of BYTE_ORDER etc.

sys/types.h only conditionally defines caddr_t and clockid_t.

	* sysdeps/unix/sysv/linux/sys/quota.h:
	Use __caddr_t instead of caddr_t.
	* sysdeps/unix/sysv/linux/sys/timerfd.h:
	Use __clockid_t instead of clockid_t.

Remove a #warning that was the sole actual problem with using sys/ipc.h
without _GNU_SOURCE/_XOPEN_SOURCE.

	* sysvipc/sys/ipc.h: Remove unnecessary #warning.

_LIBC, __USE_XOPEN2K8, and __STDC_VERSION__ are not always defined.

It seems to me that _LIBC should not appear in installed headers, but
avoiding that for argp specifically would require more surgery than
feels appropriate for this patch set.  It's possible that
"#ifdef _LIBC" would be sufficient, but I wanted to be conservative.

All three versions of bits/socket.h want to know whether __flexarr
will produce a real flexible array member -- specifically, one that
doesn't alter sizeof(the structure containing it).  They were testing
for this with a complicated #if condition that did not agree with
sys/cdefs.h and that tripped -Wundef warnings under -std=c90.
I added a new macro to sys/cdefs.h, __glibc_c99_flexarr_available,
which reveals exactly what these headers want to know.  I also took
the opportunity to flatten the rather messy conditional nest defining
__flexarr.

	* argp/argp.h: Check whether _LIBC is defined before expanding it.
	* posix/glob.h: Check whether __USE_XOPEN2K8 is defined instead
	of expanding it.

	* misc/sys/cdefs.h: Tidy up conditional nest defining __flexarr.
	Define __glibc_c99_flexarr_available to 1 when the compiler
	supports C99-compatible flexible array members, 0 otherwise.
	* sysdeps/unix/sysv/linux/bits/socket.h
	* sysdeps/mach/hurd/bits/socket.h
	* bits/socket.h: Use __glibc_c99_flexarr_available in
	definitions of struct cmsghdr and CMSG_DATA.

1c1e7fb658 Fix macro API for __USE_KERNEL_IPV6_DEFS.
The use of __USE_KERNEL_IPV6_DEFS with ifndef is bad
practice per: https://sourceware.org/glibc/wiki/Wundef.
This change moves it to use 'if' and always define the
macro.

Please note that this is not the only problem with this
code. I have a series of fixes after this one to resolve
breakage with this code and add regression tests for it
via compile-only source testing (to be discussed in another
thread).

Unfortunately __USE_KERNEL_XATTR_DEFS is set by the kernel
and not glibc, and uses 'define', so we can't fix that yet.

3375cfafa7 Make padding in struct sockaddr_storage explicit [BZ #20111]
This avoids aliasing issues with GCC 6 in -fno-strict-aliasing
mode.  (With implicit padding, not all data is copied.)

This change makes it explicit that struct sockaddr_storage is
only 126 bytes large on m68k (unlike elsewhere, where we end up
with the requested 128 bytes).  The new test case makes sure that
this does not happen on other architectures.

9dd346ff43 Convert 113 more function definitions to prototype style (files with assertions).
This mostly automatically-generated patch converts 113 function
definitions in glibc from old-style K&R to prototype-style.  Following
my other recent such patches, this one deals with the case of function
definitions in files that either contain assertions or where grep
suggested they might contain assertions - and thus where it isn't
possible to use a simple object code comparison as a sanity check on
the correctness of the patch, because line numbers are changed.

A few such automatically-generated changes needed to be supplemented
by manual changes for the result to compile.  openat64 had a prototype
declaration with "..." but an old-style definition in
sysdeps/unix/sysv/linux/dl-openat64.c, and "..." needed adding to the
generated prototype in the definition (I've filed
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68024> for diagnosing
such cases in GCC; the old state was undefined behavior not requiring
a diagnostic, but one seems a good idea).  In addition, as Florian has
noted regparm attribute mismatches between declaration and definition
are only diagnosed for prototype definitions, and five functions
needed internal_function added to their definitions (in the case of
__pthread_mutex_cond_lock, via the macro definition of
__pthread_mutex_lock) to compile on i386.

After this patch is in, remaining old-style definitions are probably
most readily fixed manually before we can turn on
-Wold-style-definition for all builds.
