#ifndef _TIME_H
Installed-header hygiene (BZ#20366): time.h types. 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.

# include <struct___timespec64.h>
# include <struct___timeval64.h>
Rename xlocale.h to bits/types/__locale_t.h. xlocale.h is already a single-type micro-header, defining struct __locale_struct and the typedefs __locale_t and locale_t. This patch brings it into the bits/types/ scheme: there are now bits/types/__locale_t.h which defines only __locale_struct and __locale_t, and bits/types/locale_t.h which defines locale_t as well as the other two. None of *our* headers need __locale_t.h, but it appears to me that libstdc++ could make use of it. There are a lot of external uses of xlocale.h, but all the uses I checked had an autoconf test or equivalent for its existence. It has never been available from other C libraries, and it has always contained a comment reading "This file is not standardized, don't rely on it, it can go away without warning" so I think dropping it is pretty safe. I also took the opportunity to clean up comments in various public header files that still talk about the *_l interfaces as though they were completely nonstandard. There are a few of them, notably the strtoX_l and wcstoX_l families, that haven't been standardized, but the bulk are in POSIX.1-2008. * locale/xlocale.h: Rename to... * locale/bits/types/__locale_t.h: ...here. Adjust commentary. Only define struct __locale_struct and __locale_t, not locale_t. * locale/bits/types/locale_t.h: New file; define locale_t here. * locale/Makefile (headers): Update to match. * include/xlocale.h: Delete wrapper. * include/bits/types/__locale_t.h: New wrapper. * include/bits/types/locale_t.h: New wrapper. * ctype/ctype.h, include/printf.h, include/time.h * locale/langinfo.h, locale/locale.h, stdlib/monetary.h * stdlib/stdlib.h, string/string.h, string/strings.h, time/time.h * wcsmbs/wchar.h, wctype/wctype.h: Use bits/types/locale_t.h. Correct outdated comments regarding the standardization status of the functions that take locale_t arguments. * stdlib/strtod_l.c, stdlib/strtof_l.c, stdlib/strtol_l.c * stdlib/strtold_l.c, stdlib/strtoul_l.c, stdlib/strtoull_l.c * sysdeps/ieee754/ldbl-128ibm/strtold_l.c * sysdeps/ieee754/ldbl-64-128/strtold_l.c * wcsmbs/wcstod.c, wcsmbs/wcstod_l.c, wcsmbs/wcstof.c * wcsmbs/wcstof_l.c, wcsmbs/wcstold.c, wcsmbs/wcstold_l.c: Don't include xlocale.h. If necessary, include locale.h instead. * stdlib/strtold_l.c: Unconditionally include wchar.h.

Make mktime etc. compatible with __time64_t Keep these functions compatible with Gnulib while adding __time64_t support. The basic idea is to move private API declarations from include/time.h to time/mktime-internal.h, since the former file cannot easily be shared with Gnulib whereas the latter can. Also, do some other minor cleanup while in the neighborhood. * include/time.h: Include stdbool.h, time/mktime-internal.h.

(__localtime64_r, __gmtime64_r) [__TIMESIZE == 64]: Move these macros to time/mktime-internal.h, since Gnulib needs them. (__mktime64, __timegm64) [__TIMESIZE != 64]: New prototypes. (in_time_t_range): New static function. * posix/bits/types.h (__time64_t) [__TIMESIZE == 64 && !defined __LIBC]: Do not define as a macro in this case, so that portable code is less tempted to use __time64_t. * time/mktime-internal.h: Rewrite so that it does both glibc and Gnulib work. Include time.h if not _LIBC. (mktime_offset_t) [!_LIBC]: Define for gnulib. (__time64_t, __gmtime64_r, __localtime64_r, __mktime64, __timegm64) [!_LIBC || __TIMESIZE == 64]: New macros, mostly moved here from include/time.h. (__gmtime_r, __localtime_r, __mktime_internal) [!_LIBC]: New macros, taken from GNulib. (__mktime_internal): New prototype, moved here from include/time.h. * time/mktime.c (mktime_min, mktime_max, convert_time) (ranged_convert, __mktime_internal, __mktime64): * time/timegm.c (__timegm64): Use __time64_t, not time_t. * time/mktime.c: Stop worrying about whether time_t is floating-point. (__mktime64) [! (_LIBC && __TIMESIZE != 64)]: Rename from mktime. (mktime) [_LIBC && __TIMESIZE != 64]: New function. * time/timegm.c [!_LIBC]: Include libc-config.h, not config.h, for libc_hidden_def. Include errno.h. (__timegm64) [! (_LIBC && __TIMESIZE != 64)]: Rename from timegm. (timegm) [_LIBC && __TIMESIZE != 64]: New function. First cut at publicizing __time64_t

y2038: linux: Provide __clock_getres64 implementation This patch provides new __clock_getres64 explicit 64 bit function for getting the resolution (precision) of specified clock ID. Moreover, a 32 bit version - __clock_getres has been refactored to internally use __clock_getres64. The __clock_getres is now supposed to be used on systems still supporting 32 bit time (__TIMESIZE != 64) - hence the necessary conversion from 64 bit struct __timespec64 to struct timespec. The new clock_getres_time64 syscall available from Linux 5.1+ has been used, when applicable. On systems which are not supporting clock_getres_time64 (as their clock_getres supports 64 bit time ABI) the vDSO syscall is attempted. On the contrary the non-vDSO syscall is used for clock_getres_time64 as up till now the kernel is not providing such interface. No additional checks (i.e. if tv_nsec value overflow) are performed on values returned via clock_getres{_time64} syscall, as it is assumed that the Linux kernel will either return 0 and provide correct value or error. The check for tv_sec being out of range on systems still supporting 32 bit time (__TIMESIZE != 64) without Y2038 time support is also omitted as it is _very_ unlikely that we would have a timer with resolution which exceeds 32 bit time_t range.

y2038: linux: Provide __utimensat64 implementation This patch provides new __utimensat64 explicit 64 bit function for setting access and modification time of a file. Moreover, a 32 bit version - __utimensat has been refactored to internally use __utimensat64. The __utimensat is now supposed to be used on systems still supporting 32 bit time (__TIMESIZE != 64) - hence the necessary conversions to 64 bit struct __timespec64. When pointer to struct __timespec64 is NULL - the file access and modification time is set to the current one and no conversions from struct timespec to __timespec64 are performed. The new utimensat_time64 syscall available from Linux 5.1+ has been used, when applicable. The new helper function - __utimensat64_helper - has been introduced to facilitate code re-usage on function providing futimens syscall handling. The Linux kernel checks if passed tv_nsec value overflows, so there is no need to repeat it in glibc. When utimensat syscall on systems supporting 32 bit time ABI is used, the check is performed if passed data (which may have 64 bit tv_sec) fits into 32 bit range. Build tests: - The code has been tested on x86_64/x86 (native compilation): make PARALLELMFLAGS="-j8" && make xcheck PARALLELMFLAGS="-j8" - The glibc has been build tested (make PARALLELMFLAGS="-j8") for x86 (i386), x86_64-x32, and armv7 Run-time tests: - Run specific tests on ARM/x86 32bit systems (qemu): https://github.com/lmajewski/meta-y2038 and run tests: https://github.com/lmajewski/y2038-tests/commits/master - Use of cross-test-ssh.sh for ARM (armv7): make PARALLELMFLAGS="-j8" test-wrapper='./cross-test-ssh.sh root@192.168.7.2' xcheck Linux kernel, headers and minimal kernel version for glibc build test matrix: - Linux v5.1 (with utimensat_time64) and glibc build with v5.1 as minimal kernel version (--enable-kernel="5.1.0") The __ASSUME_TIME64_SYSCALLS flag defined. - Linux v5.1 and default minimal kernel version The __ASSUME_TIME64_SYSCALLS not defined, but kernel supports utimensat_time64 syscall. - Linux v4.19 (no utimensat_time64 support) with default minimal kernel version for contemporary glibc This kernel doesn't support utimensat_time64 syscall, so the fallback to utimensat is tested. The above tests were performed with Y2038 redirection applied as well as without (so the __TIMESIZE != 64 execution path is checked as well). No regressions were observed.

y2038: linux: Provide __time64 implementation In the glibc the time function can use vDSO (on power and x86 the USE_IFUNC_TIME is defined), time syscall or 'default' time() from ./time/time.c (as a fallback). In this patch the last function (time) has been refactored and moved to ./sysdeps/unix/sysv/linux/time.c to be Linux specific. The new __time64 explicit 64 bit function for providing 64 bit value of seconds after epoch (by internally calling __clock_gettime64) has been introduced. Moreover, a 32 bit version - __time has been refactored to internally use __time64. The __time is now supposed to be used on systems still supporting 32 bit time (__TIMESIZE != 64) - hence the necessary check for time_t potential overflow. The iFUNC vDSO direct call optimization has been removed from both i686 and powerpc32 (USE_IFUNC_TIME is not defined for those architectures anymore). The Linux kernel does not provide a y2038 safe implementation of time neither it plans to provide it in the future, __clock_gettime64 should be used instead. Keeping support for this optimization would require to handle another build permutation (!__ASSUME_TIME64_SYSCALLS && USE_IFUNC_TIME which adds more complexity and has limited use (since the idea is to eventually have a y2038 safe glibc build). Build tests: ./src/scripts/build-many-glibcs.py glibcs Run-time tests: - Run specific tests on ARM/x86 32bit systems (qemu): https://github.com/lmajewski/meta-y2038 and run tests: https://github.com/lmajewski/y2038-tests/commits/master Above tests were performed with Y2038 redirection applied as well as without to test proper usage of both __time64 and __time.
