Subject: IPv6 addresses stay tentative (Linux 5.4.6, 5.4.7)


https://roy.marples.name/archives/dhcpcd-discuss/0002774.html

p.s.: I am using accept_ra = 2, because forwarding is also enabled.

Hello,

it seems something in the kernel code changed in regard to setting IPv6
addresses usable (i.e. dad done). Since 5.4.6 IPv6 addresses setup
statically or via autoconf (router advertisements) seem so stay in
"tentative" state forever.

I did not experience this behaviour in 5.3.13 (*) and it seems I am not
the only one affected:

I turned dhcpcd off to test whether it happens without it and indeed the
problem seems to be unrelated to dhcpcd.

Does anyone know about a recent change that may cause this behaviour?

Best regards,

Nico

(*) I cannot boot kernels 5.4.x < 5.4.6, as the wifi card does not show
up with them.
