2017-08-30Fix mcontext_t sigcontext namespace (bug 21457).Joseph Myers
This patch completes the ucontext.h namespace fixes by fixing issues related to the use of struct sigcontext as mcontext_t, and inclusion of <bits/sigcontext.h> even when struct sigcontext is not so used. Inclusion of <bits/sigcontext.h> by <sys/ucontext.h> is removed; the way to get the sigcontext structure is by including <signal.h> (in a context where __USE_MISC is defined); the sysdeps/generic version of sys/ucontext.h keeps the inclusion by necessity, with a comment about how this is not namespace-clean, but the only configuration that used it, MicroBlaze, gets its own version of the header in this patch. Where mcontext_t was typedefed to struct sigcontext, the contents of struct sigcontext are inserted (with appropriate namespace handling to prefix fields with __ when __USE_MISC is not defined); review should check that this has been done correctly in each case, whether the definition of struct sigcontext comes from glibc headers or from the Linux kernel. This changes C++ name mangling on affected architectures (which do not include x86_64/x86). Tested for x86_64, and with build-many-glibcs.py. 2017-08-14 Joseph Myers <joseph@codesourcery.com> [BZ #21457] * sysdeps/arm/sys/ucontext.h: Do not include <bits/sigcontext.h>. * sysdeps/generic/sys/ucontext.h: Add comment about use of struct sigcontext and namespace requirements. * sysdeps/i386/sys/ucontext.h: Do not include <bits/sigcontext.h>. * sysdeps/m68k/sys/ucontext.h: Likewise. * sysdeps/mips/sys/ucontext.h: Likewise.

2017-08-09Fix uc_* namespace (bug 21457).Joseph Myers
The standard members of ucontext_t, in all standard versions with that type, are uc_link, uc_sigmask, uc_stack and uc_mcontext. The uc_* namespace is mostly reserved for additions to the structure. However, in XPG4.2, it's only reserved when <ucontext.h> is included, not when <signal.h> is included, while <signal.h> is required to define ucontext_t (but not allowed to make visible other symbols from <ucontext.h>). Thus, nonstandard members should avoid uc_* names. Some already do use __uc_*, but others don't; most architectures (all except ia64, I think) have a member uc_flags and some have additional members beyond that. This patch makes nonstandard members have an __ prefix unless __USE_MISC is defined. Members whose names indicate they are solely padding / reserved for future use are renamed unconditionally to use the __glibc_reserved1 naming convention. This is part of the preparation for a revised version of the mcontext_t / sigcontext patch to be able to eliminate all 13 of the miscellaneous XFAILs in conform/Makefile, rather than only 11 of them as at present (at least one further fix on top of this one will be needed for that as well).

2017-06-26Rename struct ucontext tag (bug 21457).Joseph Myers
The ucontext_t type has a tag struct ucontext. As with previous such issues for siginfo_t and stack_t, this tag is not permitted by POSIX (is not in a reserved namespace), and so namespace conformance means breaking C++ name mangling for this type. In this case, the type does need to have some tag rather than just a typedef name, because it includes a pointer to itself. This patch uses struct ucontext_t as the new tag, so the type is mangled as ucontext_t (the POSIX *_t reservation applies in all namespaces, not just the namespace of ordinary identifiers). Another reserved name such as struct __ucontext could of course be used. Because of other namespace issues, this patch does not by itself fix bug 21457 or allow any XFAILs to be removed.

2017-06-01Fix more namespace issues in sys/ucontext.h (bug 21457).Joseph Myers
Continuing the fixes for namespace issues in sys/ucontext.h, this patch moves various symbols into the implementation namespace in the absence of __USE_MISC. As with previous changes, it is nonexhaustive, just covering more straightforward cases. Structure fields are generally changed to have a prefix __ in the absence of __USE_MISC, via a macro __ctx (used without a space before the open parenthesis, since the result is a single identifier). Various macros such as NGREG also have leading __ added. No changes are made to structure tags (and thus to C++ name mangling), except that in the (unused) file sysdeps/i386/sys/ucontext.h, structures defined inside other structures as the type for a field have their tags removed in the non-__USE_MISC case (those structure tags would not in any case have been visible in C++, because in C++ the scope of such a tag is limited to the containing structure). No changes are made to the contents of bits/sigcontext.h, or to whether it is included. Because of remaining namespace issues, this patch does not yet fix the bug or allow any XFAILs to be removed.

2017-05-23Fix sys/ucontext.h namespace from signal.h etc. inclusion (bug 21457).Joseph Myers
The various sys/ucontext.h headers include <signal.h> and all the headers split out of <bits/sigstack.h>. (Except that the powerpc version does not include <signal.h>.) None of the standard versions defining ucontext.h require or permit such inclusions; rather, they all say that the stack_t and sigset_t types from signal.h are defined. This patch fixes the headers to include just the bits/ headers for those types (and the existing includes of bits/sigcontext.h). Since bits/types/sigset_t.h is now being included instead of bits/types/__sigset_t.h, __sigset_t uses in the headers are replaced by direct use of the public sigset_t type. sysdeps/unix/sysv/linux/x86/bits/sigcontext.h was relying on the prior inclusion of <signal.h> to define types such as __uint32_t, so gets a bits/types.h include added to provide those types. Although one could keep some or all of the includes under a __USE_MISC conditional, that seems unnecessary to me, especially given the lack of a <signal.h> include in the powerpc version meaning that portable programs already cannot rely on such an include. Tested for x86_64 and x86, and with build-many-glibcs.py. As with other such fixes, more namespace issues remain so this does not permit any XFAILs to be removed or bugs to be closed.

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. 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.

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.

2017-05-11Condition some sys/ucontext.h contents on __USE_MISC (bug 21457).Joseph Myers
Continuing the fixes for namespace issues arising from sys/ucontext.h, this patch conditions various definitions, that are not needed for defining mcontext_t / ucontext_t, on __USE_MISC, so they do not appear in strict POSIX modes. This patch is non-exhaustive; that is, it only conditions straightforward cases and there may be more such definitions that can be conditioned for these and other architectures, to be dealt with later in separate patches. Also, using __USE_MISC is the minimum change for these definitions where they conflict with POSIX; some headers already have __USE_GNU conditionals on similar definitions of names for registers. The patch specifically does not do anything with definitions in bits/sigcontext.h, and nor does it condition any inclusions of bits/sigcontext.h even where in fact that is not needed on some architectures for the definitions of mcontext_t / ucontext_t. As other namespace issues in these headers remain, this patch does not fix bug 21457, nor allow any XFAILs to be removed. Tested with build-many-glibcs.py.

2016-09-23Installed-header hygiene (BZ#20366): stack_t.Zack Weinberg
sys/ucontext.h unconditionally uses stack_t, and it does not make sense to change that. But signal.h only declares stack_t under __USE_XOPEN_EXTENDED || __USE_XOPEN2K8. The actual definition is already in a bits header, bits/sigstack.h, but that header insists on only being included by signal.h, so we have to change that as well as all of the sys/ucontext.h variants. (Some but not all variants of bits/sigcontext.h, which sys/ucontext.h may also need, had already received this adjustment; for consistency, I made them all the same, even if that's not strictly necessary in some configurations.) bits/sigcontext.h and bits/sigstack.h also all need to receive multiple inclusion guards. * sysdeps/generic/sys/ucontext.h * sysdeps/arm/sys/ucontext.h * sysdeps/i386/sys/ucontext.h * sysdeps/m68k/sys/ucontext.h * sysdeps/mips/sys/ucontext.h * sysdeps/unix/sysv/linux/aarch64/sys/ucontext.h * sysdeps/unix/sysv/linux/alpha/sys/ucontext.h * sysdeps/unix/sysv/linux/arm/sys/ucontext.h * sysdeps/unix/sysv/linux/hppa/sys/ucontext.h * sysdeps/unix/sysv/linux/ia64/sys/ucontext.h * sysdeps/unix/sysv/linux/m68k/sys/ucontext.h * sysdeps/unix/sysv/linux/mips/sys/ucontext.h * sysdeps/unix/sysv/linux/nios2/sys/ucontext.h * sysdeps/unix/sysv/linux/powerpc/sys/ucontext.h * sysdeps/unix/sysv/linux/s390/sys/ucontext.h * sysdeps/unix/sysv/linux/sh/sys/ucontext.h * sysdeps/unix/sysv/linux/sparc/sys/ucontext.h * sysdeps/unix/sysv/linux/tile/sys/ucontext.h * sysdeps/unix/sysv/linux/x86/sys/ucontext.h: Include both bits/sigcontext.h and bits/sigstack.h.
