      [IPV6] addrconf: Fix IPv6 on tuntap tunnels · 74235a25
      由 Herbert Xu 提交于 
      The recent patch that added ipv6_hwtype is broken on tuntap tunnels.
Indeed, it's broken on any device that does not pass the ipv6_hwtype
test.

The reason is that the original test only applies to autoconfiguration,
not IPv6 support.  IPv6 support is allowed on any device.  In fact,
even with the ipv6_hwtype patch applied you can still add IPv6 addresses
to any interface that doesn't pass thw ipv6_hwtype test provided that
they have a sufficiently large MTU.  This is a serious problem because
come deregistration time these devices won't be cleaned up properly.

I've gone back and looked at the rationale for the patch.  It appears
that the real problem is that we were creating IPv6 devices even if the
MTU was too small.  So here's a patch which fixes that and reverts the
ipv6_hwtype stuff.

Thanks to Kanru Chen for reporting this issue.

      [XFRM]: Allow packet drops during larval state resolution. · 14e50e57
      由 David S. Miller 提交于 
      The current IPSEC rule resolution behavior we have does not work for a
lot of people, even though technically it's an improvement from the
-EAGAIN buisness we had before.

Right now we'll block until the key manager resolves the route.  That
works for simple cases, but many folks would rather packets get
silently dropped until the key manager resolves the IPSEC rules.

We can't tell these folks to "set the socket non-blocking" because
they don't have control over the non-block setting of things like the
sockets used to resolve DNS deep inside of the resolver libraries in
libc.

With that in mind I coded up the patch below with some help from
Herbert Xu which provides packet-drop behavior during larval state
resolution, controllable via sysctl and off by default.

This lays the framework to either:

1) Make this default at some point or...

2) Move this logic into xfrm{4,6}_policy.c and implement the
   ARP-like resolution queue we've all been dreaming of.
   The idea would be to queue packets to the policy, then
   once the larval state is resolved by the key manager we
   re-resolve the route and push the packets out.  The
   packets would timeout if the rule didn't get resolved
   in a certain amount of time.
