Add a check for the given tv_usec, so that the value stays below one
second.
Additionally limit the tv_sec value to a reasonable value for CAN related
use-cases of 400 days and ensure all values to be positive.
This patch is the pre-4.8 version of upstream commit 93171ba6f1deffd8
I can't find this commit id upstream, there's nothing with the same
subject name, nor does this code exist upstream. What's going on?
Here we are (pulled by Linus some minutes ago):
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=93171ba6f1deffd82f381d36cb13177872d023f6
Can you go with this pre-4.8 version now?
Many thanks,
Oliver
