* y2038: Add support for 64-bit time on legacy ABIsAdhemerval Zanella2021-06-151-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A new build flag, _TIME_BITS, enables the usage of the newer 64-bit time symbols for legacy ABI (where 32-bit time_t is default). The 64 bit time support is only enabled if LFS (_FILE_OFFSET_BITS=64) is also used. Different than LFS support, the y2038 symbols are added only for the required ABIs (armhf, csky, hppa, i386, m68k, microblaze, mips32, mips64-n32, nios2, powerpc32, sparc32, s390-32, and sh). The ABIs with 64-bit time support are unchanged, both for symbol and types redirection. On Linux the full 64-bit time support requires a minimum of kernel version v5.1. Otherwise, the 32-bit fallbacks are used and might results in error with overflow return code (EOVERFLOW). The i686-gnu does not yet support 64-bit time. This patch exports following rediretions to support 64-bit time: * libc: adjtime adjtimex clock_adjtime clock_getres clock_gettime clock_nanosleep clock_settime cnd_timedwait ctime ctime_r difftime fstat fstatat futimens futimes futimesat getitimer getrusage gettimeofday gmtime gmtime_r localtime localtime_r lstat_time lutimes mktime msgctl mtx_timedlock nanosleep nanosleep ntp_gettime ntp_gettimex ppoll pselec pselect pthread_clockjoin_np pthread_cond_clockwait pthread_cond_timedwait pthread_mutex_clocklock pthread_mutex_timedlock pthread_rwlock_clockrdlock pthread_rwlock_clockwrlock pthread_rwlock_timedrdlock pthread_rwlock_timedwrlock pthread_timedjoin_np recvmmsg sched_rr_get_interval select sem_clockwait semctl semtimedop sem_timedwait setitimer settimeofday shmctl sigtimedwait stat thrd_sleep time timegm timerfd_gettime timerfd_settime timespec_get utime utimensat utimes utimes wait3 wait4 * librt: aio_suspend mq_timedreceive mq_timedsend timer_gettime timer_settime * libanl: gai_suspend Reviewed-by: Lukasz Majewski <lukma@denx.de> Reviewed-by: Carlos O'Donell <carlos@redhat.com> Tested-by: Carlos O'Donell <carlos@redhat.com>

* sysconf: Add _SC_MINSIGSTKSZ/_SC_SIGSTKSZ [BZ #20305]H.J. Lu2021-02-013-2/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add _SC_MINSIGSTKSZ for the minimum signal stack size derived from AT_MINSIGSTKSZ, which is the minimum number of bytes of free stack space required in order to gurantee successful, non-nested handling of a single signal whose handler is an empty function, and _SC_SIGSTKSZ which is the suggested minimum number of bytes of stack space required for a signal stack. If AT_MINSIGSTKSZ isn't available, sysconf (_SC_MINSIGSTKSZ) returns MINSIGSTKSZ. On Linux/x86 with XSAVE, the signal frame used by kernel is composed of the following areas and laid out as: ------------------------------ | alignment padding | ------------------------------ | xsave buffer | ------------------------------ | fsave header (32-bit only) | ------------------------------ | siginfo + ucontext | ------------------------------ Compute AT_MINSIGSTKSZ value as size of xsave buffer + size of fsave header (32-bit only) + size of siginfo and ucontext + alignment padding. If _SC_SIGSTKSZ_SOURCE or _GNU_SOURCE are defined, MINSIGSTKSZ and SIGSTKSZ are redefined as /* Default stack size for a signal handler: sysconf (SC_SIGSTKSZ). */ # undef SIGSTKSZ # define SIGSTKSZ sysconf (_SC_SIGSTKSZ) /* Minimum stack size for a signal handler: SIGSTKSZ. */ # undef MINSIGSTKSZ # define MINSIGSTKSZ SIGSTKSZ Compilation will fail if the source assumes constant MINSIGSTKSZ or SIGSTKSZ. The reason for not simply increasing the kernel's MINSIGSTKSZ #define (apart from the fact that it is rarely used, due to glibc's shadowing definitions) was that userspace binaries will have baked in the old value of the constant and may be making assumptions about it. For example, the type (char [MINSIGSTKSZ]) changes if this #define changes. This could be a problem if an newly built library tries to memcpy() or dump such an object defined by and old binary. Bounds-checking and the stack sizes passed to things like sigaltstack() and makecontext() could similarly go wrong.

* Remove tls.h inclusion from internal errno.hAdhemerval Zanella2020-11-132-0/+2
| | | | | | | | | | | | The tls.h inclusion is not really required and limits possible definition on more arch specific headers.

* signal: Move sys_siglist to a compat symbolAdhemerval Zanella2020-07-071-6/+0
| | | | | | | | | | | | | | | | | | | The symbol was deprecated by strsignal and its usage imposes issues such as copy relocations. Its internal name is changed to __sys_siglist and __sys_sigabbrev to avoid static linking usage. The compat code is also refactored, since both Linux and Hurd usage the same strategy: export the same array with different object sizes. The libSegfault change avoids calling strsignal on the SIGFAULT signal handler (the current usage is already sketchy, adding a call that potentially issue locale internal function is even sketchier). Checked on x86_64-linux-gnu and i686-linux-gnu. I also run a check-abi on all affected platforms. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
* signal: Add signum-{generic,arch}.hAdhemerval Zanella2020-07-072-2/+2
| | | | | | | | | | | | | | | | | | | | It refactor how signals are defined by each architecture. Instead of include a generic header (bits/signum-generic.h) and undef non-default values in an arch specific header (bits/signum.h) the new scheme uses a common definition (bits/signum-generic.h) and each architectures add its specific definitions on a new header (bits/signum-arch.h). For Linux it requires copy some system default definitions to alpha, hppa, and sparc. They are historical values and newer ports uses the generic Linux signum-arch.h. For Hurd the BSD signum is removed and moved to a new header (it is used currently only on Hurd). Checked on a build against all affected ABIs.

* signal: Deprecate additional legacy signal handling functionsFlorian Weimer2020-05-253-7/+23
| | | | | | | | | | This needs a few test adjustments: In some cases, sigignore was used for convenience (replaced with xsignal with SIG_IGN). Tests for the deprecated functions need to disable -Wdeprecated-declarations, and for the sigmask deprecation, -Wno-error. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

* signal: Only handle on NSIG signals on signal functions (BZ #25657)Adhemerval Zanella2020-04-213-6/+102
| | | | | | | | | | | | | | | The upper bits of the sigset_t s not fully initialized in the signal mask calls that return information from kernel (sigprocmask, sigpending, and pthread_sigmask), since the exported sigset_t size (1024 bits) is larger than Linux support one (64 or 128 bits). It might make sigisemptyset/sigorset/sigandset fail if the mask is filled prior the call. This patch changes the internal signal function to handle up to supported Linux signal number (_NSIG), the remaining bits are untouched. Checked on x86_64-linux-gnu and i686-linux-gnu.
* Build raise with -fasynchronous-unwind-tables.Joseph Myers2020-01-241-0/+1
| | | | | | | | | | | | | | | In testing glibc for Arm and MIPS, I see: FAIL: misc/tst-sigcontext-get_pc If this test - backtracing through a call to raise - is valid, then raise needs to be built with -fasynchronous-unwind-tables (as the test itself is) to have the required unwind information for that backtracing to work. Adding that option, which this patch does, causes the test for pass for Arm. For MIPS, the test still does not pass (the backtrace has an address that is 2 bytes after the "address in signal handler", for unknown reasons), although the patch allows a longer backtrace to be produced.

* Tests for minimal signal handler functionality in MINSIGSTKSZ space.Zack Weinberg2019-01-166-0/+397
| | | | | | | | | | | | | | | | | | | | | | | There is general agreement that the very short list of things that ISO C says you can do in an async signal handler should all work when the handler is running on an alternate signal stack with only MINSIGSTKSZ space.

* Filter out NPTL internal signals (BZ #22391)Adhemerval Zanella2018-04-035-38/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch filters out the internal NPTL signals (SIGCANCEL/SIGTIMER and SIGSETXID) from signal functions. GLIBC on Linux requires both signals to proper implement pthread cancellation, posix timers, and set*id posix thread synchronization. And not filtering out the internal signal is troublesome: - A conformant program on a architecture that does not filter out the signals might inadvertently disable pthread asynchronous cancellation, set*id synchronization or posix timers. - It might also to security issues if SIGSETXID is masked and set*id functions are called (some threads might have effective user or group id different from the rest). The changes are basically: - Change __is_internal_signal to bool and used on all signal function that has a signal number as input. Also for signal function which accepts signals sets (sigset_t) it assumes that canonical function were used to add/remove signals which lead to some input simplification. - Fix tst-sigset.c to avoid check for SIGCANCEL/SIGTIMER and SIGSETXID. It is rewritten to check each signal indidually and to check realtime signals using canonical macros. - Add generic __clear_internal_signals and __is_internal_signal version since both symbols are used on generic implementations. - Remove superflous sysdeps/nptl/sigfillset.c. - Remove superflous SIGTIMER handling on Linux __is_internal_signal since it is the same of SIGCANCEL. - Remove dangling define and obvious comment on nptl/sigaction.c.

* sigwait: Do not fail with EINTR and return error code [BZ #22478]Florian Weimer2017-11-232-2/+87

* Fix sigval namespace (bug 21944).Joseph Myers2017-08-164-9/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>.

* Factor out shared definitions from bits/signum.h.Zack Weinberg2017-06-202-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Fix struct sigaltstack namespace (bug 21517).Joseph Myers2017-06-052-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Fix sigevent namespace (bug 21543).Joseph Myers2017-06-021-1/+4
| | | | | | | | | | | | | | | | | | 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].
* Fix sigstack namespace (bug 21511).Joseph Myers2017-05-231-7/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | 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].

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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | These are called from the kernel with the stack at a carefully- chosen location so that the stack frame can be restored: they must not move the stack pointer lest garbage be restored into the registers. We explicitly inhibit protection for SPARC and for signal/sigreturn.c: other arches either define their sigreturn stubs in .S files, or (i386, x86_64, mips) use macros expanding to top-level asm blocks and explicit labels in the text section to mock up a "function" without telling the compiler that one is there at all.

This conversion is deliberately simplistic, excluding any tricky cases as even a patch covering only simple cases is still very large. Currently excluded are: sysdeps files (to improve test coverage for the initial patch); files containing assertions (to avoid line number changes so that generated libraries can be compared); any cases where the generated function declaration would involve lines over 79 characters and so need to be wrapped; any cases with array parameters or other cases where parameter declarators don't end with the parameter name; any other cases that my script didn't parse. I didn't try to make the ChangeLog generation indicate when function definitions are conditional; it just lists the functions changed without regard to that. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * crypt/cert.c (good_bye): Convert to prototype-style function definition.

* Fix psignal, psiginfo declaration conditions (bug 18483).Joseph Myers2015-06-051-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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]. Remove redundant #if. * conform/Makefile (test-xfail-XOPEN2K/signal.h/linknamespace): Remove variable. (test-xfail-XOPEN2K/sys/wait.h/linknamespace): Likewise. (test-xfail-XOPEN2K/ucontext.h/linknamespace): Likewise.
