* Fix libm feraiseexcept namespace (bug 17723).Joseph Myers2014-12-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various C90 and UNIX98 libm functions call feraiseexcept, which is not in those standards. This causes linknamespace test failures - except on x86 / x86_64, where feraiseexcept is inline (for the relevant constant arguments) in bits/fenv.h. This patch fixes this by making those functions call __feraiseexcept instead. All changes are applied to all architectures rather than considering the possibility that some might not be needed in some cases (e.g. x86) as it seems most maintainable to keep architectures consistent. Where __feraiseexcept does not exist, it is added, with feraiseexcept made a weak alias; where it is a strong alias, it is made weak. libm_hidden_def / libm_hidden_proto are used with __feraiseexcept (this might in some cases improve code generation for existing calls to __feraiseexcept in some code on some architectures). Where there are dummy feraiseexcept macros (on architectures without floating-point exceptions support, to avoid compile errors from references to undefined FE_* macros), corresponding dummy __feraiseexcept macros are added. And on x86, to ensure __feraiseexcept calls still get inlined, the inline function in bits/fenv.h is refactored so that most of it can be reused in an inline __feraiseexcept in a separate include/bits/fenv.h. Calls are changed in C90/UNIX98 functions, but generally not in functions missing from those standards. They are also changed in libc_fe* functions (on the basis that those might be used in any libm function), and in feupdateenv (on the same basis - may be used, via default libc_*, in any libm function - of course feupdateenv will need changing to __feupdateenv in a subsequent patch to make that fully namespace-clean). No __feraiseexcept is added corresponding to the feraiseexcept in powerpc bits/fenvinline.h, because that macro definition is conditional on !defined __NO_MATH_INLINES, and glibc libm is built with -D__NO_MATH_INLINES, so changing internal calls to use __feraiseexcept should make no difference. Tested for x86_64 (testsuite; the only change in disassembly of installed shared libraries is a slight code reordering in clog10, of no apparent significance). Also tested for MIPS, where (in the configuration tested) it eliminates math.h linknamespace failures for n32 and n64 (some for o32 remain because of other issues).

* linux/clock_settime: remove unnecessary vDSO definitionsChris Metcalf2014-12-261-9/+0
| | | | | | | | | | | | These definitions were added back before __ASSUME_POSIX_CPU_TIMERS was removed. There used to be a vsyscall to clock_getres() in maybe_syscall_settime_cpu(), but that function was removed in commit 26889eac. The presence of the vsyscall definitions means that platforms that don't provide clock_getres as a vsyscall hit a symbol redefinition warning in this file, becoming fatal with -Werror. Removing the vsyscall definitions is the obvious fix. No change to generated code on x86_64.
* tilegx: fix sysdep.h to avoid a redefinition warningChris Metcalf2014-12-261-3/+3
| | | | | | | | The symbol for HAVE_CLOCK_GETTIME_VSYSCALL was being only conditionally defined under [SHARED]. However, it turns out this causes a preprocessor symbol redefinition warning when building clock_gettime.o. Move the symbol definition down to make it unconditional, like other platforms do.
* Make __ASSUME_UTIMES hppa-specific.Joseph Myers2014-12-226-44/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes __ASSUME_UTIMES hppa-specific, removing mentions of the macro from architecture-independent code and code for other architectures. (All other architectures either have the utimes syscall in all relevant kernel versions, or use the asm-generic interface so only have utimensat and won't get the utimes syscall.) A similar approach is used to that used for futimesat for MicroBlaze: if the kernel is recent enough that the utimes syscall can be assumed to be present, use the implementation in terms of the utimes syscall, and otherwise use the linux/generic implementation in terms of utimensat. Tested x86_64 that the disassembly of installed shared libraries is unchanged by the patch. Not tested for hppa. * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_UTIMES): Do not define. * sysdeps/unix/sysv/linux/utimes.c: Do not include <kernel-features.h>.

* Fix resolver bind, getsockname namespace (bug 17733).Joseph Myers2014-12-222-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | On Linux architectures using socketcall, the resolver ends up bringing in strong symbols for bind and getsockname, which are not in POSIX.1-1996. This causes linknamespace test failures: FAIL: conform/POSIX/pthread.h/linknamespace FAIL: conform/POSIX/sched.h/linknamespace FAIL: conform/POSIX/time.h/linknamespace These functions are defined as strong symbols with __bind and __getsockname as weak aliases. This patch switches this to the other way round by removing the NO_WEAK_ALIAS definitions and so letting the default case in socket.S act; I see no reason for the existing arrangements. Tested for x86 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). [BZ #17733] * sysdeps/unix/sysv/linux/bind.S (NO_WEAK_ALIAS): Do not define. (__bind): Do not define as weak alias. * sysdeps/unix/sysv/linux/getsockname.S (NO_WEAK_ALIAS): Do not define. (__getsockname): Do not define as weak alias.

* Fix profil_counter namespace (bug 17725).Joseph Myers2014-12-1711-11/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On ARM, where profil_counter is not static, it is brought in by references to various standard functions, as noted in <https://sourceware.org/ml/libc-alpha/2014-11/msg00890.html>, although it is not a standard function itself. I don't know if this also causes test failures on SPARC, although I see no reason for it not to do so. This patch fixes this namespace issue. profil_counter is renamed to __profil_counter and made a weak alias on ARM and SPARC. Because of the uses in profil.c / sprofil.c it seems simplest to make the rename globally, including on the other architectures for which profil_counter was static and so the change is of no substance. The variant names profil_counter_* used in sprofil.c are also renamed to start with __ so that undesired function names do not get exported in static libc. As I noted in bug 17726, profil_counter should probably be a compat symbol on ARM and SPARC, so it wouldn't exist at all in static libc even as a weak alias. Since defining a compat symbol still requires an internal name as a target of an alias, this patch still seems reasonable as an intermediate step towards that goal: it wouldn't be possible for the function simply to be static profil_counter on ARM and SPARC with profil_counter also being the exported compat symbol name, so profil.c / sprofil.c would still need to be prepared to call the function under another name (here, __profil_counter). Tested for x86_64 (testsuite, and that stripped installed shared libraries are unchanged by the patch) and ARM (ABI and linknamespace tests - this patch reduces the number of linknamespace failures I see on ARM from 227 to 5, the residue being math.h failures for fe* functions and for j0l/j1n/jnl/y0l/y1l/ynl aliases). 2014-12-17 Joseph Myers <joseph@codesourcery.com> [BZ #17725] * sysdeps/generic/profil-counter.h (profil_counter): Rename to __profil_counter. * sysdeps/unix/sysv/linux/hppa/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/i386/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/ia64/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/sh/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/tile/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/x86_64/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/arm/profil-counter.h (profil_counter): Likewise.

* Fix sysdeps/unix/sysv/linux/arm/libc-do-syscall.S warning.Joseph Myers2014-11-261-0/+3
| | | | | | | | | | | | | | | | | This patch fixes a warning ../include/features.h:328:4: warning: #warning _FORTIFY_SOURCE requires compiling with optimization (-O) [-Wcpp] seen when building for ARM. This warning comes from libc-do-syscall.S being built for nscd: the nscd build uses _FORTIFY_SOURCE, while .S files aren't built with -O, and the combination produces a warning. As _FORTIFY_SOURCE doesn't do anything for .S files, undefining it in libc-do-syscall.S seems the simplest solution. Tested for ARM. * sysdeps/unix/sysv/linux/arm/libc-do-syscall.S (_FORTIFY_SOURCE): Undefine.

* Add new macro IN_MODULE to identify module in which source is builtSiddhesh Poyarekar2014-11-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current scheme to identify which module a translation unit is built in depends on defining multiple macros IS_IN_* and also defining NOT_IN_libc if we're building a non-libc module. In addition, there is an IN_LIB macro that does effectively the same thing, but for different modules (notably the systemtap probes). This macro scheme unifies both ideas to use just one macro IN_MODULE and assign it a value depending on the module it is being built into. If the module is not defined, it defaults to MODULE_libc. Patches that follow will replace uses of IS_IN_* variables with the IS_IN() macro. libc-symbols.h has been converted already to give an example of how such a transition will look. Verified that there are no relevant binary changes. One source change that will crop up repeatedly is that of nscd_stat, since it uses the build timestamp as a constant in its logic. * Makeconfig (in-module): Get value of libof set for the translation unit.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | __get_nprocs is called from malloc code, but calls fgets_unlocked, which is not an ISO C or POSIX function. This patch fixes it to call a new __fgets_unlocked name instead. Note: there are various other uses of fgets_unlocked in glibc's libraries, and I haven't yet investigated which others might also be problematic (called directly or indirectly from standard functions) and so need to change to use __fgets_unlocked.

* Run check-localpltk/textrel/execstack over ld.so.Carlos O'Donell2014-11-0613-0/+115
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For maximum paranoia we run ld.so through the normal set of tests for all of the shared libraries. This includes running ld.so through check-localplt, check-textrel, and check-execstack. While none of these should trigger any failures given the way ld.so is built, it might possibly fail if a developer does something wrong. This paranoia was triggered by a discussion over the use of __strcpy vs. strcpy [1] and if the symbol could leak and use the libc.so version. The check-localplt test fails right away because localplt.data needs updating for all arches. By default we add 6 new symbols: __tls_get_addr, __libc_memalign, malloc, calloc, realloc and free. Other machines like i386, power, and s390 require some different symbol sets e.g. ___tls_get_addr vs. __tls_get_addr for i386.

| | | | | * sysdeps/unix/sysv/linux/sparc/sys/ucontext.h (struct fpu): fix the size of the fpu_fr.fpu_dregs[] array.
* Remove __libc_nanosleep function name.Joseph Myers2014-11-011-1/+1
| | | | | | | | | | | | | | | Continuing the removal of unused __libc_* function names, this patch removes the __libc_nanosleep name. Tested for x86_64 (testsuite, and that the disassembly of installed shared libraries is unchanged by the patch; __nanosleep changes from weak to strong, which is of no significance). * posix/nanosleep.c (__libc_nanosleep): Rename to __nanosleep. (__nanosleep): Do not define as alias. (nanosleep): Define as alias of __nanosleep. * sysdeps/unix/sysv/linux/syscalls.list (nanosleep): Remove __libc_nanosleep name.
