This patch implements functionality for following time64 syscalls:
*clock_getres_time64
This a year 2038 safe variant of syscall:
int clock_getres(clockid_t clockid, struct timespec *res)
--finding the resoultion of a specified clock--
man page: https://man7.org/linux/man-pages/man2/clock_getres.2.html
*timer_gettime64
*timer_settime64
These are year 2038 safe variants of syscalls:
int timer_settime(timer_t timerid, int flags,
const struct itimerspec *new_value,
struct itimerspec *old_value)
int timer_gettime(timer_t timerid, struct itimerspec *curr_value)
--arming/dissarming and fetching state of POSIX per-process timer--
man page: https://man7.org/linux/man-pages/man2/timer_settime.2.html
*timerfd_gettime64
*timerfd_settime64
These are year 2038 safe variants of syscalls:
int timerfd_settime(int fd, int flags,
const struct itimerspec *new_value,
struct itimerspec *old_value)
int timerfd_gettime(int fd, struct itimerspec *curr_value)
--timers that notify via file descriptor--
man page: https://man7.org/linux/man-pages/man2/timerfd_settime.2.html
Implementation notes:
Syscall 'clock_getres_time64' was implemented similarly to 'clock_getres()'.
The only difference was that for the conversion of 'struct timespec' from
host to target, function 'host_to_target_timespec64()' was used instead of
'host_to_target_timespec()'.
For other syscalls, new functions 'host_to_target_itimerspec64()' and
'target_to_host_itimerspec64()' were added to convert the value of the
'struct itimerspec' from host to target and vice versa. A new type
'struct target__kernel_itimerspec' was added in 'syscall_defs.h'. This
type was defined with fields which are of the already defined type
'struct target_timespec'. This new 'struct target__kernel_itimerspec'
type is used in these new converting functions. These new functions were
defined similarly to 'host_to_target_itimerspec()' and 'target_to_host_itimerspec()'
the only difference being that 'target_to_host_timespec64()' and
'host_to_target_timespec64()' were used.
