From 42893aa38fd6041d349ea0427c4d5ccbacd9a2be Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Thu, 24 Oct 2019 14:34:46 +0200 Subject: y2038: linux: Provide __futimens64 implementation This patch provides new __futimens64 explicit 64 bit function for setting access and modification time of file (by using its file descriptor). Moreover, a 32 bit version - __futimens has been refactored to internally use __futimens64. The __futimens 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 (by the kernel) and no conversions from struct timespec to __timespec64 are performed. The __futimens64 reuses __utimensat64_helper defined for __utimensat64. The test procedure for __futimens64 is the same as for __utimensat64 conversion patch. --- sysdeps/unix/sysv/linux/futimens.c | 22 +++++++++++++++++++--- 1 file changed, 19 insertions(+), 3 deletions(-) (limited to 'sysdeps/unix/sysv/linux/futimens.c') diff --git a/sysdeps/unix/sysv/linux/futimens.c b/sysdeps/unix/sysv/linux/futimens.c index 1f233d1246..15fc43b69c 100644 --- a/sysdeps/unix/sysv/linux/futimens.c +++ b/sysdeps/unix/sysv/linux/futimens.c @@ -29,10 +29,26 @@ Starting with 2.6.22 the Linux kernel has the utimensat syscall which can be used to implement futimens. */ int -futimens (int fd, const struct timespec tsp[2]) +__futimens64 (int fd, const struct __timespec64 tsp64[2]) { if (fd < 0) return INLINE_SYSCALL_ERROR_RETURN_VALUE (EBADF); - /* Avoid implicit array coercion in syscall macros. */ - return INLINE_SYSCALL (utimensat, 4, fd, NULL, &tsp[0], 0); + + return __utimensat64_helper (fd, NULL, &tsp64[0], 0); +} + +#if __TIMESIZE != 64 +int +__futimens (int fd, const struct timespec tsp[2]) +{ + struct __timespec64 tsp64[2]; + if (tsp) + { + tsp64[0] = valid_timespec_to_timespec64 (tsp[0]); + tsp64[1] = valid_timespec_to_timespec64 (tsp[1]); + } + + return __futimens64 (fd, tsp ? &tsp64[0] : NULL); } +#endif +weak_alias (__futimens, futimens) -- cgit v1.2.3-70-g09d2
