* Fix sys/time.h timespec namespace (bug 20041).Joseph Myers2016-05-031-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | For UNIX98 and older standards, sys/time.h should not define struct timespec, but does so via the inclusion of sys/select.h (which is a new header in the 2001 edition of POSIX, and defines struct timespec because of the declaration of pselect, a new function in the 2001 edition of POSIX). In turn, this affects some other headers that themselves include sys/time.h. This patch fixes this by conditioning the __need_timespec definition in sys/select.h on __USE_XOPEN2K, the same condition used there for the declaration of pselect (this has no effect on direct uses of sys/select.h with feature test macros for any standard that includes that header, since such standards result in __USE_XOPEN2K being defined). Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). [BZ #20041] * misc/sys/select.h (__need_timespec): Only define if [__USE_XOPEN2K]. * conform/Makefile (test-xfail-XPG4/sys/time.h/conform): Remove variable. (test-xfail-XPG4/utmpx.h/conform): Likewise. (test-xfail-UNIX98/sys/time.h/conform): Likewise. (test-xfail-UNIX98/utmpx.h/conform): Likewise.

* Make __extern_always_inline usable on clang++ againSiddhesh Poyarekar2014-09-161-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fix for BZ #17266 (884ddc5081278f488ef8cd49951f41cfdbb480ce) removed changes that had gone into cdefs.h to make __extern_always_inline usable with clang++. This patch adds back support for clang to detect if GNU inlining semantics are available, this time without breaking the gcc use case. The check put here is based on the earlier patch and assertion[1] that checking if __GNUC_STDC_INLINE__ or __GNUC_GNU_INLINE__ is defined is sufficient to determine that clang++ suports GNU inlining semantics. Tested with a simple program that builds with __extern_always_inline with the patch and fails compilation without it. #include <stdio.h> #include <sys/cdefs.h> extern void foo_alias (void) __asm ("foo"); __extern_always_inline void foo (void) { puts ("hi oh world!"); return foo_alias (); } void foo_alias (void) { puts ("hell oh world"); } int main () { foo (); } [1] https://sourceware.org/ml/libc-alpha/2012-12/msg00306.html [BZ #17266] * misc/sys/cdefs.h: Define __extern_always_inline for clang 4.2 and newer.
* Revert to defining __extern_inline only for gcc-4.3+ (BZ #17266)Siddhesh Poyarekar2014-09-161-10/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The check for only __GNUC_STDC_INLINE__ and __GNUC_GNU_INLINE__ may not be sufficient since those flags were added during initial support for C99 inlining semantics. There is also a problem with always defining __extern_inline and __extern_always_inline, since it enables inline wrapper functions even when GNU inlining semantics are not guaranteed. This, along with the possibility of such wrappers using redirection (btowc for example) could result in compiler generating an infinitely recusrive call to the function. In fact it was such a recursion that led to this code being written the way it was; see: https://bugzilla.redhat.com/show_bug.cgi?id=186410 The initial change was to fix bugs 14530 and 13741, but they can be resolved by checking if __fortify_function and/or __extern_always_inline are defined, as it has been done in this patch. In addition, I have audited uses of __extern_always_inline to make sure that none of the uses result in compilation errors. There is however a regression in this patch for llvm, since it reverts the llvm expectation that __GNUC_STDC_INLINE__ or __GNUC_GNU_INLINE__ definition imply proper extern inline semantics. 2014-09-16 Siddhesh Poyarekar <siddhesh@redhat.com> Jakub Jelinek <jakub@redhat.com> [BZ #17266] * libio/stdio.h: Check definition of __fortify_function instead of __extern_always_inline to include bits/stdio2.h. * math/bits/math-finite.h [__USE_XOPEN || __USE_ISOC99]: Also check if __extern_always_inline is defined. [__USE_MISC || __USE_XOPEN]: Likewise. [__USE_ISOC99] Likewise. * misc/sys/cdefs.h (__fortify_function): Define only if __extern_always_inline is defined. [!__cplusplus || __GNUC_PREREQ (4,3)]: Revert to defining __extern_always_inline and __extern_inline only for g++-4.3 and newer or a compatible gcc.
* Fix Wundef warning for __STDC_VERSION__Siddhesh Poyarekar2014-07-031-1/+3
| | | | | | | | c4c4124473c187b5c4642611390897666c3d3970 added the _Noreturn macro for pre-C11 compilers, but it now throws a new Wundef warning during `make check` for __STDC_VERSION__ which gcc does not define by default. The following patch fixes this in line with other uses of __STDC_VERSION__ in the file.
* misc/sys/cdefs.h: Add _Noreturn macro for pre-C11 compilersPaul Eggert2014-07-021-0/+8

* misc/sys/xattr.h: guard against linux uapi header inclusionSerge Hallyn2014-03-181-0/+2
| | | | | | | | | | | | | | | | If the glibc xattr.h header is included after the uapi header, compilation fails due to an enum re-using a #define from the uapi header. Protect against this by guarding the define and enum inclusions against each other. (A corresponding kernel patch has been sent here: http://lkml.org/lkml/2014/3/7/331 ) (See https://lists.debian.org/debian-glibc/2014/03/msg00029.html and https://sourceware.org/glibc/wiki/Synchronizing_Headers for more information.)

* Complete _BSD_SOURCE / _SVID_source followup cleanup.Joseph Myers2014-02-211-1/+1

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.

* Combine __USE_BSD and __USE_SVID into __USE_MISC.Joseph Myers2014-02-123-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch cleans up following the obsoletion of _BSD_SOURCE and _SVID_SOURCE by combining __USE_BSD and __USE_SVID into __USE_MISC. 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.)

* Add error reporting (via errno) to getauxval().Brooks Moses2013-12-181-2/+2
| | | | | | | | | | | | [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().

* Use __gnu_inline__ for __extern_always_inline in g++-4.2Richard Smith2013-05-011-8/+6
| | | | | | | | | | | | | Use the __gnu_inline__ attribute in _FORTIFY_SOURCE's __extern_always_inline macro whenever the compiler supports it. Previously this macro only included the __gnu_inline__ attribute in C++ mode for gcc >= 4.3. However, __gnu_inline__ semantics are always desired for the __extern_always_inline functions, and are available in g++ 4.2 (and some releases of g++ 4.1, and also in Clang, which claims to be g++ 4.2). This change stops g++-4.2 from emitting weak definitions for the fortify wrapper functions if they can't be inlined, and also improves Clang compatibility.

(__warnattr): Define. * stdlib/bits/stdlib.h (__realpath_chk_warn, __ptsname_r_chk_warn, __mbstowcs_chk_warn, __wcstombs_chk_warn): New aliases with __warnattr. (realpath, ptsname_r, mbstowcs, wcstombs): Call __*_chk_warn instead of __*_chk if compile time detectable overflow is found. * libio/bits/stdio2.h (__fgets_chk_warn, __fread_chk_warn, __fgets_unlocked_chk_warn, __fread_unlocked_chk_warn): New aliases with __warnattr. (fgets, fread, fgets_unlocked, fread_unlocked): Call __*_chk_warn instead of __*_chk if compile time detectable overflow is found. (__gets_alias): Rename to... (__gets_warn): ... this. Add __warnattr. (gets): Call __gets_warn instead of __gets_alias. * socket/bits/socket2.h (__recv_chk_warn, __recvfrom_chk_warn): New aliases with __warnattr. (recv, recvfrom): Call __*_chk_warn instead of __*_chk if compile time detectable overflow is found. * posix/bits/unistd.h (__read_chk_warn, __pread_chk_warn, __pread64_chk_warn, __readlink_chk_warn, __readlinkat_chk_warn, __getcwd_chk_warn, __confstr_chk_warn, __getgroups_chk_warn, __ttyname_r_chk_warn, __getlogin_r_chk_warn, __gethostname_chk_warn, __getdomainname_chk_warn): New aliases with __warnattr. (read, pread, pread64, readlink, readlinkat, getcwd, confstr, getgroups, ttyname_r, getlogin_r, gethostname, getdomainname): Call __*_chk_warn instead of __*_chk if compile time detectable overflow is found.
