#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 <bits/types/struct_timeval.h>
# 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.

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.

(__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_settime64 implementation This patch provides new __clock_settime64 explicit 64 bit function for setting the time. Moreover, a 32 bit version - __clock_settime - has been refactored to internally use __clock_settime64. The __clock_settime is now supposed to be used on systems still supporting 32 bit time (__TIMESIZE != 64) - hence the necessary conversion to 64 bit struct timespec. The new clock_settime64 syscall available from Linux 5.1+ has been used, when applicable. In this patch the internal padding (tv_pad) of struct __timespec64 is left untouched (on systems with __WORDSIZE == 32) as Linux kernel ignores upper 32 bits of tv_nsec. 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 clock_settime64) 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 __clock_settime64 syscalls. - Linux v4.19 (no clock_settime64 support) with default minimal kernel version for contemporary glibc This kernel doesn't support __clock_settime64 syscalls, so the fallback to clock_settime 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).

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.

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.

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.

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.

Make mktime etc. compatible with __time64_t Keep these functions compatible with Gnulib while adding __time64_t support.

Also, do some other minor cleanup while in the neighborhood. * include/time.h: Include stdbool.h, time/mktime-internal.h.

(__mktime64) [! (_LIBC && __TIMESIZE != 64)]: Rename from mktime.
