This command uses the old ioctl(SIOCADDRT) API which in turn generates
none 2001:db8:1:15::/64 via 2001:db8:1:1::15 dev ve0 metric 1 pref medium
with rtm_type == RTN_UNKNOWN (0), which is obviously wrong.
Looks like the kernel ioctl handler will copy the type if userspace sets it:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/net/...
but 'route' doesn't set it:
https://sourceforge.net/p/net-tools/code/ci/master/tree/lib/inet6_sr.c
Hi
Thanks, i am wondering if that is a change in kernel, route command, or just nobody noticed it before.
A bit of git archaeology points suggestively at this commit: https://git.kernel.org/torvalds/c/e8478e80e5a
From April 2018; so looks like it might actually be a regression in the kernel. I'll send a bug report to netdev...
