Vincenzo Frascino 520e3bd3de mips: Fix gettimeofday() in the vdso library ... [ Upstream commit 7d2aa4bb90 ] The libc provides a discovery mechanism for vDSO library and its symbols. When a symbol is not exposed by the vDSOs the libc falls back on the system calls. With the introduction of the unified vDSO library on mips this behavior is not honored anymore by the kernel in the case of gettimeofday(). The issue has been noticed and reported due to a dhclient failure on the CI20 board: root@letux:~# dhclient ../../../../lib/isc/unix/time.c:200: Operation not permitted root@letux:~# Restore the original behavior fixing gettimeofday() in the vDSO library.
