* Remove C++ namespace handling from glibc headers.Joseph Myers2017-03-161-14/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glibc headers include some code (not particularly consistent or systematic) to put various declarations in C++ namespaces std and __c99, if _GLIBCPP_USE_NAMESPACES is defined. As noted in <https://gcc.gnu.org/ml/libstdc++/2017-03/msg00025.html>, this macro was removed from libstdc++ in 2000. I don't expect compilation with such old versions of libstdc++ to work with current glibc headers anyway (whereas old *binaries* are expected to stay working with current glibc); this patch (which should be a no-op with any libstdc++ version postdating that removal) removes all this code from the glibc headers. The begin-end-check.pl test, whose comments say it is about checking these namespace macro calls, is also removed. The code in that test would have covered __BEGIN_DECLS / __END_DECLS as well, but if those weren't properly matched it would show up with the check-installed-headers-cxx tests, so I don't think there is an actual use for keeping begin-end-check.pl with the namespace code removed. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * misc/sys/cdefs.h (__BEGIN_NAMESPACE_STD): Remove macro.

* New string function explicit_bzero (from OpenBSD).Zack Weinberg2016-12-161-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | explicit_bzero(s, n) is the same as memset(s, 0, n), except that the compiler is not allowed to delete a call to explicit_bzero even if the memory pointed to by 's' is dead after the call. Right now, this effect is achieved externally by having explicit_bzero be a function whose semantics are unknown to the compiler, and internally, with a no-op asm statement that clobbers memory. This does mean that small explicit_bzero operations cannot be expanded inline as small memset operations can, but on the other hand, small memset operations do get deleted by the compiler. Hopefully full compiler support for explicit_bzero will happen relatively soon. There are two new tests: test-explicit_bzero.c verifies the visible semantics in the same way as the existing test-bzero.c, and tst-xbzero-opt.c verifies the not-being-optimized-out property. The latter is conceptually based on a test written by Matthew Dempsky for the OpenBSD regression suite. The crypt() implementation has an immediate use for this new feature. We avoid having to add a GLIBC_PRIVATE alias for explicit_bzero by running all of libcrypt's calls through the fortified variant, __explicit_bzero_chk, which is in the impl namespace anyway. Currently I'm not aware of anything in libc proper that needs this, but the glue is all in place if it does become necessary. The legacy DES implementation wasn't bothering to clear its buffers, so I added that, mostly for consistency's sake. * string/explicit_bzero.c: New routine. * string/test-explicit_bzero.c, string/tst-xbzero-opt.c: New tests. * string/Makefile (routines, strop-tests, tests): Add them. * string/test-memset.c: Add ifdeffage for testing explicit_bzero. * string/string.h [__USE_MISC]: Declare explicit_bzero. * debug/explicit_bzero_chk.c: New routine. * debug/Makefile (routines): Add it. * debug/tst-chk1.c: Test fortification of explicit_bzero. * string/bits/string3.h: Fortify explicit_bzero. * manual/string.texi: Document explicit_bzero. * NEWS: Mention addition of explicit_bzero. * crypt/crypt-entry.c (__crypt_r): Clear key-dependent intermediate data before returning, using explicit_bzero. * crypt/md5-crypt.c (__md5_crypt_r): Likewise. * crypt/sha256-crypt.c (__sha256_crypt_r): Likewise. * crypt/sha512-crypt.c (__sha512_crypt_r): Likewise. * include/string.h: Redirect internal uses of explicit_bzero to __explicit_bzero_chk[_internal]. * string/Versions [GLIBC_2.25]: Add explicit_bzero. * debug/Versions [GLIBC_2.25]: Add __explicit_bzero_chk. * sysdeps/arm/nacl/libc.abilist * sysdeps/unix/sysv/linux/aarch64/libc.abilist * sysdeps/unix/sysv/linux/alpha/libc.abilist * sysdeps/unix/sysv/linux/arm/libc.abilist * sysdeps/unix/sysv/linux/hppa/libc.abilist * sysdeps/unix/sysv/linux/i386/libc.abilist * sysdeps/unix/sysv/linux/ia64/libc.abilist * sysdeps/unix/sysv/linux/m68k/coldfire/libc.abilist * sysdeps/unix/sysv/linux/m68k/m680x0/libc.abilist * sysdeps/unix/sysv/linux/microblaze/libc.abilist * sysdeps/unix/sysv/linux/mips/mips32/fpu/libc.abilist * sysdeps/unix/sysv/linux/mips/mips32/nofpu/libc.abilist * sysdeps/unix/sysv/linux/mips/mips64/n32/libc.abilist * sysdeps/unix/sysv/linux/mips/mips64/n64/libc.abilist * sysdeps/unix/sysv/linux/nios2/libc.abilist * sysdeps/unix/sysv/linux/powerpc/powerpc32/fpu/libc.abilist * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/libc.abilist * sysdeps/unix/sysv/linux/powerpc/powerpc64/libc-le.abilist * sysdeps/unix/sysv/linux/powerpc/powerpc64/libc.abilist * sysdeps/unix/sysv/linux/s390/s390-32/libc.abilist * sysdeps/unix/sysv/linux/s390/s390-64/libc.abilist * sysdeps/unix/sysv/linux/sh/libc.abilist * sysdeps/unix/sysv/linux/sparc/sparc32/libc.abilist * sysdeps/unix/sysv/linux/sparc/sparc64/libc.abilist * sysdeps/unix/sysv/linux/tile/tilegx/tilegx32/libc.abilist * sysdeps/unix/sysv/linux/tile/tilegx/tilegx64/libc.abilist * sysdeps/unix/sysv/linux/tile/tilepro/libc.abilist * sysdeps/unix/sysv/linux/x86_64/64/libc.abilist * sysdeps/unix/sysv/linux/x86_64/x32/libc.abilist: Add entries for explicit_bzero and __explicit_bzero_chk.

* Support __STDC_WANT_LIB_EXT2__ feature test macro.Joseph Myers2016-08-021-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements support for the __STDC_WANT_LIB_EXT2__ feature test macro from ISO/IEC TR 24731-2:2010, thereby implementing one possible approach for supporting ISO C feature test macros. Recall that, as described in <https://sourceware.org/ml/libc-alpha/2016-05/msg00486.html>, these macros work based on the definition when affected headers are included, so cannot be handled once when the first system header is included because that might not be one of the headers the particular macro in question affects. <https://sourceware.org/ml/libc-alpha/2016-05/msg00680.html> expresses views on possible approaches for implementation and <https://sourceware.org/ml/libc-alpha/2016-06/msg00039.html> follows up on that. This patch arranges things so that the relevant condition is __GLIBC_USE (LIB_EXT2), following one of the suggestions given. Headers using these macros include <bits/libc-header-start.h>, which in turn includes <features.h>. Headers must define __GLIBC_INTERNAL_STARTING_HEADER_IMPLEMENTATION before including <bits/libc-header-start.h>, to discourage inclusion outside glibc as requested. __USE_GNU conditions on affected functions are changed to __GLIBC_USE (LIB_EXT2), while it's added as an additional alternative on the conditions for functions already enabled for some POSIX versions. It would be possible to convert existing __USE_* conditionals to __GLIBC_USE (with the relevant __GLIBC_USE_* being defined in <features.h> where __USE_* are presently defined), and so make them typo-proof (given -Wundef -Werror in glibc builds) because __GLIBC_USE is used with #if not #ifdef / #if defined. No attempt is made to enforce the rule about diagnosing different definitions of __STDC_WANT_LIB_EXT2__ when affected headers are included; such a diagnostic is incompatible with multiple-include guards on the affected headers, unless compiler extensions are added to support it. As previously noted, glibc does not implement all features from TR 24731-2:2010: the functions aswprintf vaswprintf getwdelim getwline are not in glibc, although they would be appropriate to add if someone wished to do so. But I think it makes sense to support the feature test macro if *any* of the controlled features are present in glibc. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * bits/libc-header-start.h: New file. * Makefile (headers): Add bits/libc-header-start.h. * include/features.h (__STDC_WANT_LIB_EXT2__): Document.

This includes cases such as __USE_MISC || __USE_ISOC99, where __USE_MISC is redundant (because __USE_MISC is only ever defined in the default / _DEFAULT_SOURCE / _GNU_SOURCE case, when __USE_ISOC99 is also defined; the same applies to the non-XSI-extended POSIX versions), and cases involving __USE_GNU, where __USE_GNU is redundant (because if __USE_GNU is defined, so are the other __USE_* macros). There may well be other cases of __USE_FOO || __USE_BAR tests that could be simplified because one macro implies the other; this patch only addresses cases involving __USE_MISC.

* Clean up trivially redundant __USE_MISC conditionals.Joseph Myers2014-02-131-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch cleans up cases of __USE_MISC that are trivially redundant after the recent substitution of __USE_MISC for __USE_BSD and __USE_SVID: either in constructs such as "defined __USE_MISC || defined __USE_MISC", or else (in the bits/mman.h case) a conditional on __USE_MISC nested inside another __USE_MISC conditional. (The cleanups remaining after this patch are still quite large, but it seems a reasonable piece to separate out.)

The only non-mechanical part of this patch is the changes to features.h; everything else is simple substitution of __USE_MISC for the old macros. Thus, this patch leaves obviously redundant conditionals such as "defined __USE_MISC || defined __USE_MISC", and does not update #endif comments where they referred to BSD or SVID in words instead of the literal macro name. This is intended to facilitate patch review by separating the less mechanical changes from these purely mechanical changes into a separate patch. (I do intend to integrate all the changes from <https://sourceware.org/ml/libc-alpha/2013-12/msg00226.html>, which I believe includes all the trailing comment updates, in subsequent patches.)

* Define __CORRECT_ISO_CPP_STRING_H_PROTO correctly for Clang.Brooks Moses2013-12-231-2/+6
| | | | | | | | | | | | | | | | | | | | | In the string/string.h and string/strings.h headers, we have a couple of macros that "tell the caller that we provide correct C++ prototypes" according to the comment; they are used to determine whether to wrap some prototypes in "extern "C++"" (and provide multiple overloads of them, and some other magic) when __cplusplus is defined. The macros are set to check for sufficiently-recent GCC versions (4.4 and later), but this is not the right check for non-GCC compilers. In particular, these macros should also be set when using Clang -- if they are not set, then Clang will be unable to correctly diagnose a number of subtle bugs that will be errors in GCC compilations. As per discussion on earlier versions of this patch, rather than restrict the fix to Clang per se, we assume that all C++ compilers that claim to fully support C++98 are using a standard-conforming C++ standard library, which seems pretty reasonable. Clang has been providing an appropriate value of __cplusplus since May 2012.
* Remove __GNUC__ conditions for "long long" from string.h and wchar.h.Joseph Myers2013-01-101-2/+0

* Add __wur to GNU version of strerror_r.Cyril Hrubis2012-06-151-3/+2
| | | | | | | | Not using the result of the GNU strerror_r() is always a mistake. Moreover this would generate warning if XSI version was expected but GNU version was used instead (because some random used header defined _GNU_SOURCE which was Python.h in this case).
