Re: [PATCH net-next] sit: do not report an error from ipip6_fill_info()

在 2026/9/12 08:54, Eric Dumazet 写道:

ipip6_fill_info() returns -ENODEV if tunnel->sit_parms is NULL.

This can not happen yet: sit_parms is only cleared from
ipip6_dev_free(), the priv_destructor, which runs long after
RTM_DELLINK has been built.

Returning an error from a fill_info() handler is still a trap,
because rtnl_dump_ifinfo() stops at the first failure and propagates
it, letting one device hide all the remaining ones.

Return 0 instead, there is nothing to report for a device that is
going away.
