ipv6: don't accept node local multicast traffic from the wire

2013-03-29T18:57:33+00:00

Erik Hugne's errata proposal (Errata ID: 3480) to RFC4291 has been
verified: http://www.rfc-editor.org/errata_search.php?eid=3480

We have to check for pkt_type and loopback flag because either the
packets are allowed to travel over the loopback interface (in which case
pkt_type is PACKET_HOST and IFF_LOOPBACK flag is set) or they travel
over a non-loopback interface back to us (in which case PACKET_TYPE is
PACKET_LOOPBACK and IFF_LOOPBACK flag is not set).

ipv[4|6]: correct dropwatch false positive in local_deliver_finish

2013-03-01T20:56:29+00:00

I had a report recently of a user trying to use dropwatch to localise some frame
loss, and they were getting false positives.  Turned out they were using a user
space SCTP stack that used raw sockets to grab frames.  When we don't have a
registered protocol for a given packet, we record it as a drop, even if a raw
socket receieves the frame.  We should only record the drop in the event a raw
socket doesnt exist to receive the frames

ipv6: Store Router Alert option in IP6CB directly.

2013-01-14T01:17:14+00:00

Router Alert option is very small and we can store the value
itself in the skb.

ipv6: Make ipv6_is_mld() inline and use it from ip6_mc_input().

Move generalized version of ipv6_is_mld() to header,
and use it from ip6_mc_input().

net: TCP early demux cleanup

2012-07-30T21:53:21+00:00

early_demux() handlers should be called in RCU context, and as we
use skb_dst_set_noref(skb, dst), caller must not exit from RCU context
before dst use (skb_dst(skb)) or release (skb_drop(dst))

Therefore, rcu_read_lock()/rcu_read_unlock() pairs around
->early_demux() are confusing and not needed :

Protocol handlers are already in an RCU read lock section.
(__netif_receive_skb() does the rcu_read_lock() )

inet: Sanitize inet{,6} protocol demux.

2012-06-20T01:56:21+00:00

Don't pretend that inet_protos[] and inet6_protos[] are hashes, thay
are just a straight arrays.  Remove all unnecessary hash masking.

Document MAX_INET_PROTOS.

Use RAW_HTABLE_SIZE when appropriate.
