Hi, I am trying to run v5.4-rc6 on the CI20 board (jz4780) and it is almost ok. Except one strange thing.
If I install a v4.19.81 kernel I can initialize the ethernet interface and dhclient works.
If I install a v5.4-rc6 kernel on exactly the same rootfs dhclient fails with
root@letux:~# dhclient ../../../../lib/isc/unix/time.c:200: Operation not permitted root@letux:~#
I have done some strace and the first significant difference is that with v5.4-rc6 there is no gettimeofday syscall.
Another symptom pointing in the same direction is that after manually assigning an IP address I can run ping but get strange time values.
So it may be that
24640f233b46 mips: Add support for generic vDSO
did break gettimeofday when used with latest Debian Stretch libraries. I tried to git revert but there are conflicts.
Just a side-note: both kernels work with Debian Jessie, which likely has an older gettimeofday wrapper that is not influenced by some subtle change.
BR and thanks, Nikolaus Schaller
