Kukuk: Y2038, glibc and utmp/utmpx on 64bit architectures
[Posted March 3, 2023 by corbet]
Thorsten Kukuk demonstrates
that we are not done with year-2038 problems yet.

The general statement so far has always been that on 64bit systems with a 64bit time_t you are safe with respect to the Y2038 problem. But glibc uses for compatibility with 32bit userland applications 32bit time_t in some places even on 64bit systems.
One of those places is the utmp file. The post includes a proposal for solving the problem by getting rid of utmp entirely.
