[PATCH 0/2] netns: fix for NULL-dereference in ipv6 code

[Brian Haley]

Hi,

When fixing the NULL-dereference of the idev in rt6_fill_node(), I
noticed that dev_net() doesn't handle a NULL argument either.  These two
patches fix that, as well as add a network namespace argument to
rt6_fill_node() and ipv6_dev_get_saddr().

What is the reason that dev_net() would need to handle a NULL arg?

I think a NULL pointer in dev_net is a bug if Network Namespaces are used.
