* Fix sigval namespace (bug 21944).Joseph Myers2017-08-162-8/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>.

* Remove __need macros from signal.h.Zack Weinberg2017-05-203-0/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Ports to other operating systems are strongly encouraged to generalize this scheme further. * bits/sigevent-consts.h * bits/siginfo-consts.h * bits/types/__sigset_t.h * bits/types/sigevent_t.h * bits/types/siginfo_t.h * sysdeps/unix/sysv/linux/bits/sigevent-consts.h * sysdeps/unix/sysv/linux/bits/siginfo-consts.h * sysdeps/unix/sysv/linux/bits/types/__sigset_t.h * sysdeps/unix/sysv/linux/bits/types/sigevent_t.h * sysdeps/unix/sysv/linux/bits/types/siginfo_t.h: New system-dependent bits headers. * sysdeps/unix/sysv/linux/bits/siginfo-arch.h * sysdeps/unix/sysv/linux/bits/siginfo-consts-arch.h * sysdeps/unix/sysv/linux/ia64/bits/siginfo-arch.h * sysdeps/unix/sysv/linux/ia64/bits/siginfo-consts-arch.h * sysdeps/unix/sysv/linux/mips/bits/siginfo-arch.h * sysdeps/unix/sysv/linux/sparc/bits/siginfo-arch.h * sysdeps/unix/sysv/linux/tile/bits/siginfo-arch.h * sysdeps/unix/sysv/linux/tile/bits/siginfo-consts-arch.h * sysdeps/unix/sysv/linux/x86/bits/siginfo-arch.h: New Linux-only system-dependent bits headers. * signal/bits/types/sig_atomic_t.h * signal/bits/types/sigset_t.h * signal/bits/types/sigval_t.h: New non-system-dependent bits headers. * sysdeps/generic/sigsetops.h * sysdeps/unix/sysv/linux/sigsetops.h: New internal headers. * include/bits/types/sig_atomic_t.h * include/bits/types/sigset_t.h * include/bits/types/sigval_t.h: New wrappers. * signal/sigsetops.h * bits/siginfo.h * bits/sigset.h * sysdeps/unix/sysv/linux/bits/siginfo.h * sysdeps/unix/sysv/linux/bits/sigset.h * sysdeps/unix/sysv/linux/ia64/bits/siginfo.h * sysdeps/unix/sysv/linux/mips/bits/siginfo.h * sysdeps/unix/sysv/linux/s390/bits/siginfo.h * sysdeps/unix/sysv/linux/sparc/bits/siginfo.h * sysdeps/unix/sysv/linux/tile/bits/siginfo.h * sysdeps/unix/sysv/linux/x86/bits/siginfo.h: Deleted. * signal/Makefile, sysdeps/unix/sysv/linux/Makefile: Update lists of installed headers. * posix/bits/types.h: Define __sig_atomic_t here. * signal/signal.h: Use the new bits headers; no need to handle __need_sig_atomic_t nor __need_sigset_t.

* Split up bits/sigstack.h.Joseph Myers2017-05-191-0/+29
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.
