Subject: [PATCH v2 0/7] y2038: Convert clock_adjtime related syscalls to support 64 bit time
Date: Fri, 8 May 2020 16:56:33 +0200 [thread overview]
Message-ID: <20200508145640.16336-1-lukma@denx.de> (raw)
This patch series converts clock_adjtime to support 64 bit time (by using
clock_adjtime64) when __ASSUME_TIME64_SYSCALLS is defined.
This change required introduction of new internal type - struct
__ntptimeval64 to accomodate 64 bit time on architectures
with __TIMESIZE != 64 and __WORDSIZE == 32.
In several places in the glibc the struct timeval has been replaced with struct
__timeval64.
As a result new, 64 bit supporting functions:
__adjtime64
__adjtimex64
__ntp_gettime64
__ntp_gettimex64
were introduced.
Moreover, the clock_adjtime64 syscall handling in Linux kernel has been broken
up till v5.4.
