Subject: [PATCH net 0/2] fix two kernel panics when disabled IPv6 on boot up
Date: Wed, 6 Feb 2019 20:51:09 +0800 [thread overview]
Message-ID: <20190206125111.5286-1-liuhangbin@gmail.com> (raw)
When disabled IPv6 on boot up, since there is no ipv6 route tables, we should
not call rt6_lookup. Fix them by checking if we have inet6_dev pointer on
netdevice.
Hangbin Liu (2):
geneve: should not call rt6_lookup() when ipv6 was disabled
sit: check if IPv6 enabled before call ip6_err_gen_icmpv6_unreach()
