2017-08-16Fix sigval namespace (bug 21944).Joseph Myers
XPG4.2 defines the siginfo_t type, but not union sigval or its contents (which were added in the 1993 edition of POSIX.1), resulting in namespace violations for sigval, sival_int and sival_ptr for signal.h and sys/wait.h for that standard because those headers incorrectly expose those names in that case. This patch fixes this problem. The public type in this case is union sigval, but various places in the headers use the sigval_t name for it; direct uses of union sigval are already properly guarded or in headers not in XPG4.2. Now, sigval_t, although not a standard name, does seem to be widely used outside glibc. The approach taken by this patch is to make installed headers use the name __sigval_t instead. __sigval_t is then defined to either union sigval or union __sigval (where union __sigval has __-prefixed member names as well), depending on whether there are any namespace issues with the union sigval name and its members. In the case where union __sigval is used, sigval_t is not defined at all, to avoid the problem of sigval_t having a C++ mangled name that depends on feature test macros. sigval_t is still defined by signal.h if __USE_MISC (reflecting the nonstandard nature of that name). Tested for x86_64. [BZ #21944] * signal/bits/types/__sigval_t.h: New file. * signal/Makefile (headers): Add bits/types/__sigval_t.h. * signal/bits/types/sigval_t.h: Include <bits/types/__sigval_t.h> and define sigval_t using __sigval_t. * include/bits/types/__sigval_t.h: New file. * bits/types/sigevent_t.h: Include <bits/types/__sigval_t.h> instead of <bits/types/__sigval_t.h>.

2017-06-20Factor out shared definitions from bits/signum.h.Zack Weinberg
Many of the things defined by bits/signum.h are invariant across all supported operating systems. This patch factors out all of them to a new header bits/signum-generic.h, which each bits/signum.h will include and then override whichever things need adjustment. Normally that will mean, at most, adding or changing a few signal numbers. A user-visible side effect is that the obsolete signal constant SIGUNUSED (which is an alias for SIGSYS on all platforms that define it) is no longer exposed by any version of bits/signum.h. A side effect only relevant to glibc hackers is that _NSIG is now defined in terms of __SIGRTMAX, instead of the other way around. This is because __SIGRTMAX varies from platform to platform, but _NSIG==__SIGRTMAX+1 is true universally. If your platform doesn't support realtime signals, leave __SIGRTMAX equal to __SIGRTMIN. I also added a Linux-specific test to make sure that our signal constants match the ones in <asm/signal.h>, since we can't use that header (it's not even vaguely namespace-clean). * bits/signum-generic.h: Renamed from bits/signum.h. Add proper multiple include guard and misuse check. Define __SIGRTMIN = __SIGRTMAX = 32, and define _NSIG = __SIGRTMAX+1. Move definition of SIGIO to "archaic names for compatibility" section. * bits/signum.h: New file which just includes bits/signum-generic.h. * sysdeps/unix/bsd/bits/signum.h * sysdeps/unix/sysv/linux/bits/signum.h * sysdeps/unix/sysv/linux/alpha/bits/signum.h * sysdeps/unix/sysv/linux/hppa/bits/signum.h * sysdeps/unix/sysv/linux/mips/bits/signum.h * sysdeps/unix/sysv/linux/sparc/bits/signum.h Just include <bits/signum-generic.h> and then add or adjust signal constants.

2017-06-19Fix siginterrupt namespace (bug 21597).Joseph Myers
The siginterrupt function is XSI-shaded in POSIX. glibc wrongly declares it in <signal.h> for non-XSI POSIX.1:2008. This patch fixes the conditionals (moving it into the __USE_XOPEN_EXTENDED || __USE_MISC block as the minimum conservative change, although it's not clear this obsolescent function should be declared by default). Tested for x86_64. [BZ #21597] * signal/signal.h (siginterrupt): Make declaration conditional on [__USE_XOPEN_EXTENDED || __USE_MISC].
2017-06-19Fix signal stack namespace (bug 21584).Joseph Myers
In POSIX.1:2008, various signal stack symbols - sigaltstack, SS_*, SIGSTKSZ, MINSIGSTKSZ - are all XSI-shaded. glibc wrongly makes them visible for non-XSI POSIX. This patch fixes the conditionals, leaving the symbols available for __USE_MISC as it seems likely some of them are widely used and should be visible by default. (Note that stack_t is *not* XSI-shaded and so the conditionals on that are correctly unchanged.) Tested for x86_64. [BZ #21584] * signal/signal.h: Make includes of <bits/sigstack.h> and <bits/ss_flags.h> conditional on [__USE_XOPEN_EXTENDED || __USE_MISC]. (sigaltstack): Make declaration conditional on [__USE_XOPEN_EXTENDED || __USE_MISC].
2017-06-12Fix XPG4 bsd_signal namespace (bug 21552).Joseph Myers
bsd_signal was added in XPG4.2, so should be declared for __USE_XOPEN_EXTENDED, instead of the present __USE_XOPEN condition. This patch fixes the condition accordingly. Tested for x86_64. [BZ #21552] * signal/signal.h (bsd_signal): Declare if [__USE_XOPEN_EXTENDED], not [__USE_XOPEN]. * conform/Makefile (test-xfail-XPG4/signal.h/conform): Remove.
2017-06-12Fix sigwait namespace (bug 21550).Joseph Myers
sigwait was added to POSIX in 1995; it is not in older POSIX versions or XPG4 / XPG4.2. Thus it should be declared only if __USE_POSIX199506; signal.h wrongly declares it for __USE_POSIX. (sigwaitinfo is correctly conditioned on __USE_POSIX199309.) This patch fixes the condition on the declaration of sigwait. Tested for x86_64. Because of other namespace problems this does not allow any conform/ XFAILs to be removed. [BZ #21550] * signal/signal.h (sigwait): Only declare if [__USE_POSIX199506].
2017-06-09Fix sigpause namespace (bug 21554).Joseph Myers
The sigpause function is declared for __USE_XOPEN. As it's new in XPG4.2 it should be declared only for __USE_XOPEN_EXTENDED. This patch fixes the declaration accordingly. Tested for x86_64. [BZ #21554] * signal/signal.h (sigpause):: Declare if [__USE_XOPEN_EXTENDED], not [__USE_XOPEN].
2017-06-05Fix struct sigaltstack namespace (bug 21517).Joseph Myers
glibc defines the stack_t type with the tag struct sigaltstack. This is not permitted by POSIX; sigaltstack is only reserved with file scope in the namespace of ordinary identifiers, not the tag namespace, and in the case where stack_t is obtained from ucontext.h rather than signal.h, it's not reserved with file scope at all. This patch removes the tag accordingly and updates uses in glibc of struct sigaltstack. This is similar to the removal of the "struct siginfo" tag a few years ago: C++ name mangling changes are an unavoidable consequence. A NEWS item is added to note the changed mangling. There is inevitably some risk of breaking builds of anything that relies on the struct sigaltstack name (though the first few hits I looked at from codesearch.debian.net generally seemed to involve code that could use the stack_t name conditionally, so depending on how they determine the conditionals they may work with glibc not defining the struct tag anyway). Tested for x86_64 and x86, and with build-many-glibcs.py. [BZ #21517] * bits/types/stack_t.h (stack_t): Remove struct tag. * sysdeps/unix/sysv/linux/bits/types/stack_t.h (stack_t): Likewise. * sysdeps/unix/sysv/linux/mips/bits/types/stack_t.h (stack_t): Likewise. * debug/segfault.c (install_handler): Use stack_t instead of struct sigaltstack. * hurd/hurd/signal.h (struct hurd_sigstate): Likewise. * hurd/trampoline.c (_hurd_setup_sighandler): Likewise. * include/signal.h (__sigaltstack): Likwise. * signal/sigaltstack.c (__sigaltstack): Likewise. * signal/signal.h (sigaltstack): Likewise. * sysdeps/mach/hurd/i386/signal-defines.sym (SIGALTSTACK__SS_SP__OFFSET): Likewise.

2017-06-02Fix sigevent namespace (bug 21543).Joseph Myers
signal.h defines the sigevent structure and constants if defined __USE_POSIX199309 || defined __USE_XOPEN_EXTENDED. The __USE_XOPEN_EXTENDED condition is incorrect; this structure does not appear in XSI standards before Unix98 (which implies __USE_POSIX199309). This patch fixes the conditionals accordingly (the existing conditional is correct for siginfo_t, just not for sigevent). Tested for x86_64. This does not allow any conform/ XFAILs to be removed because of other signal.h namespace bugs. [BZ #21543] * signal/signal.h: Only include <bits/types/sigevent_t.h> and <bits/sigevent-consts.h> if [__USE_POSIX199309], not if [__USE_XOPEN_EXTENDED].
2017-05-23Fix sigstack namespace (bug 21511).Joseph Myers
The sigstack function was removed in the 2001 edition of POSIX, and the sigstack structure in the 2008 edition. signal.h wrongly includes those declarations even for newer POSIX versions. This patch fixes the conditions, and conform/ expectations, accordingly. This patch makes the minimum change to when these declarations are present, leaving them visible for __USE_MISC as they would previously have been visible by default. Arguably these legacy declarations should only be visible when an old standard is specifically requested, but implementing that would require arranging for the various sigstack implementations to be able to see the struct sigstack type despite it not being in _GNU_SOURCE in that case. Tested for x86_64. [BZ #21511] * signal/signal.h: Include <bits/types/struct_sigstack.h> only if [(__USE_XOPEN_EXTENDED && !__USE_XOPEN2K8) || __USE_MISC]. (sigstack): Declare only if [(__USE_XOPEN_EXTENDED && !__USE_XOPEN2K) || __USE_MISC]. * conform/data/signal.h-data (struct sigstack): Expect type only if [!XOPEN2K8 && !POSIX2008]. (sigstack): Expect function only if [XPG42 || UNIX98].
2017-05-20Remove __need macros from signal.h.Zack Weinberg
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 declares any of those functions. The obsolete sigmask() macro no 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.

2017-05-19Split up bits/sigstack.h.Joseph Myers
bits/sigstack.h contains four things: the legacy struct sigstack type, the preferred stack_t type, the SS_* enum values and macros for signal stack sizes. These vary in different ways between glibc configurations; in particular, the stack sizes vary much more than any of the other pieces. Furthermore, these pieces have different standard namespace rules for when they should be visible (not currently visible in conform/ results both because the relevant tests are XFAILed for sys/ucontext.h namespace issues, and because some of the expectations are incorrect in the same way as the headers, e.g. neither expectations nor headers reflect that current POSIX no longer has either the sigstack function or the sigstack structure). To reduce duplication of identical definitions, and facilitate namespace fixes without requiring the same feature test macro conditions to be repeated in many versions of the same header, this patch splits bits/sigstack.h up into four headers. It keeps the stack size macros, while new bits/types/struct_sigstack.h, bits/types/stack_t.h and bits/ss_flags.h are added for the other pieces. bits/types/struct_sigstack.h is the same everywhere, bits/types/stack_t.h has three variants different in the order of the structure elements (generic = MIPS Linux, and other Linux), and bits/ss_flags.h has generic and Linux variants. This patch includes the new headers everywhere that included <bits/sigstack.h>, so should cause no difference to what any public header defines. Subsequent namespace fixes would then remove or condition some of those includes. There should be no conflicts with Zack's changes to signal.h types, beyond the trivial conflict of both making additions to signal/Makefile's headers list; the two patches affect disjoint sets of types and other definitions.

2017-05-04Fix signal.h bsd_signal namespace (bug 21445).Joseph Myers
signal.h declares bsd_signal for __USE_XOPEN. But this function was obsoleted in the 2001 edition of POSIX and removed in the 2008 edition, so it should not be declared when the 2008 edition is in use. This patch fixes the conditionals accordingly. (This does not fix any conform/ test failures because of other namespace issues in signal.h.) Tested for x86_64. [BZ #21445] * signal/signal.h [__USE_XOPEN2K8] (bsd_signal): Do not declare.
2017-03-16Remove C++ namespace handling from glibc headers.Joseph Myers
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.

2016-09-23Installed-header hygiene (BZ#20366): time.h types.Zack Weinberg
Many headers are expected to expose a subset of the type definitions in time.h. time.h has a whole bunch of messy logic for conditionally defining some its types and structs, but, as best I can tell, this has never worked 100%. In particular, __need_timespec is ineffective if _TIME_H has already been defined, which means that if you compile #include <time.h> #include <sched.h> with e.g. -fsyntax-only -std=c89 -Wall -Wsystem-headers, you will get In file included from test.c:2:0: /usr/include/sched.h:74:57: warning: "struct timespec" declared inside parameter list will not be visible outside of this definition or declaration extern int sched_rr_get_interval (__pid_t __pid, struct timespec *__t) __THROW; ^~~~~~~~ And if you want to _use_ sched_rr_get_interval in a TU compiled that way, you're hosed. This patch replaces all of that with small bits/types/TYPE.h headers as introduced earlier. time.h and bits/time.h are now *much* simpler, and a lot of other headers are slightly simpler. * time/time.h, bits/time.h, sysdeps/unix/sysv/linux/bits/time.h: Remove all logic conditional on __need macros. Move all the conditionally defined types to their own headers... * time/bits/types/clock_t.h: Define clock_t here. * time/bits/types/clockid_t.h: Define clockid_t here. * time/bits/types/struct_itimerspec.h: Define struct itimerspec here. * time/bits/types/struct_timespec.h: Define struct timespec here. * time/bits/types/struct_timeval.h: Define struct timeval here. * time/bits/types/struct_tm.h: Define struct tm here. * time/bits/types/time_t.h: Define time_t here. * time/bits/types/timer_t.h: Define timer_t here. * time/Makefile: Install the new headers. * bits/resource.h, io/fcntl.h, io/sys/poll.h, io/sys/stat.h * io/utime.h, misc/sys/select.h, posix/sched.h, posix/sys/times.h * posix/sys/types.h, resolv/netdb.h, rt/aio.h, rt/mqueue.h * signal/signal.h, pthread/semaphore.h, sysdeps/nptl/pthread.h * sysdeps/unix/sysv/linux/alpha/bits/resource.h * sysdeps/unix/sysv/linux/alpha/sys/acct.h * sysdeps/unix/sysv/linux/bits/resource.h * sysdeps/unix/sysv/linux/bits/timex.h * sysdeps/unix/sysv/linux/mips/bits/resource.h * sysdeps/unix/sysv/linux/net/ppp_defs.h * sysdeps/unix/sysv/linux/sparc/bits/resource.h * sysdeps/unix/sysv/linux/sys/acct.h * sysdeps/unix/sysv/linux/sys/timerfd.h * sysvipc/sys/msg.h, sysvipc/sys/sem.h, sysvipc/sys/shm.h * time/sys/time.h, time/sys/timeb.h Use the new bits/types headers. * include/time.h: Remove __need logic. * include/bits/time.h * include/bits/types/clock_t.h, include/bits/types/clockid_t.h * include/bits/types/time_t.h, include/bits/types/timer_t.h * include/bits/types/struct_itimerspec.h * include/bits/types/struct_timespec.h * include/bits/types/struct_timeval.h * include/bits/types/struct_tm.h: New wrapper headers.

2015-06-05Fix psignal, psiginfo declaration conditions (bug 18483).Joseph Myers
signal.h declares psignal and psiginfo if __USE_XOPEN2K - that is, for the 2001 edition of POSIX. These functions were actually added in the 2008 edition (as indicated in the header comments). This patch fixes the header conditionals. This fixes some linknamespace test failures because psiginfo uses fmemopen, which is also new in the 2008 edition, so before the header fix this appeared to the linknamespace tests as a 2001 function bringing in references to a 2008 function. The problem also appeared in conformtest header namespace test results (the conformtest data has correct conditionals for when these functions should be visible), but the affected headers still have other namespace problems so this doesn't fix any of those XFAILs. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). [BZ #18483] * signal/signal.h [__USE_XOPEN2K] (psignal): Change condition to [__USE_XOPEN2K8]. Remove redundant #endif. [__USE_XOPEN2K] (psiginfo): Change condition to [__USE_XOPEN2K8].

2014-11-14Remove sigvec.Roland McGrath
2014-11-14Only declare __sigpause in installed signal.h when necessary.Joseph Myers
This patch makes the installed signal.h declare __sigpause only when necessary (when a macro definition of sigpause makes use of __sigpause), rather than unconditionally. This fixes false positives in the linknamespace tests by making it visible to those tests that no use of ISO C functionality will actually bring in the definition of __sigpause and so bring in the other symbols defined in the same object. There is no bug filed in Bugzilla because this is fixing false positives rather than any user-visible bug. Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by this patch). * signal/signal.h (__sigpause): Only declare if [__USE_XOPEN && !__GNUC__]. * include/signal.h (__sigpause): Move declaration above call to libc_hidden_proto. * conform/Makefile (test-xfail-ISO/signal.h/linknamespace): Remove variable.

2014-02-21Complete _BSD_SOURCE / _SVID_source followup cleanup.Joseph Myers
This patch completes the headers cleanup consequent on removal of _BSD_SOURCE and _SVID_SOURCE (apart from any subsequent deprecations): * #endif conditionals that referred to BSD or SVID are updated. * Redundant __USE_* tests in cases involving __USE_MISC are removed. 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.

2014-02-12Combine __USE_BSD and __USE_SVID into __USE_MISC.Joseph Myers
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.)
