Johannes Berg reported that occaisionally, bringing an interface down or unregistering it would hang for up to 30 seconds. Using debugging output he provided it became clear that ICMP6 routes were the culprit. The problem is that ICMP6 routes live in their own world totally separate from normal ipv6 routes. So there are all kinds of special cases throughout the ipv6 code to handle this. While we should really try to unify all of this stuff somehow, for the time being let's fix this by purging the ICMP6 routes that match the device in question during rt6_ifdown().

由 Herbert Xu 提交于
Because the IPsec output function xfrm_output_resume does its own dst_output call it should always call __ip_local_output instead of ip_local_output as the latter may invoke dst_output directly. Otherwise the return values from nf_hook and dst_output may clash as they both use the value 1 but for different purposes. When that clash occurs this can cause a packet to be used after it has been freed which usually leads to a crash. Because the offending value is only returned from dst_output with qdiscs such as HTB, this bug is normally not visible. Thanks to Marco Berizzi for his perseverance in tracking this down.
