- Subject: [PATCH v8 0/3] y2038: Linux: Introduce __clock_settime64 function
This patch set introduces the conversion of clock_settime to explicit
64 bit struct __timespec64 arguments. As a result this function is now
Y2038 safe.
This work is (loosely) based on a previous development/patches:
https://libc-alpha.sourceware.narkive.com/zniMOWui/rfc-patch-00-52-make-glibc-y2038-proof#post68
Github branch (including the y2038 conversion example):
https://github.com/lmajewski/y2038_glibc/commits/glibc__clock_settime-conversion-v8
Those patches have been applied on top of master branch:
SHA1: 87accae3978c77c1a50d19ea8e3da3f0248d2612
Shall be used with provided meta-y2038 for development and testing:
https://github.com/lmajewski/meta-y2038
I've used guidelines from:
https://www.gnu.org/software/libc/manual/html_mono/libc.html
"D.2.1 64-bit time symbol handling in the GNU C Library"
to convert *clock_settime*.
and most notably from:
https://sourceware.org/glibc/wiki/Y2038ProofnessDesign#clock_gettime.28.29
Lukasz Majewski (3):
y2038: Introduce internal for glibc struct __timespec64
y2038: Provide conversion helpers for struct __timespec64
y2038: linux: Provide __clock_settime64 implementation
