SCTP does not check whether the source address of COOKIE-ECHO
chunk is the original address of INIT chunk or part of the any
address parameters saved in COOKIE in CLOSED state. So even if
the COOKIE-ECHO chunk is from any address but with correct COOKIE,
the COOKIE-ECHO chunk still be accepted. If the COOKIE is not from
a valid address, the assoc should not be established.

The sctp_endpoint_lookup_assoc() function uses a port hash
to lookup the association and then checks to see if any of
them are on the current endpoint.  However, if the current
endpoint is not bound, there can't be any associations on
it, thus we can bail early.

When  pos.v <= (void *)chunk + end - ntohs(pos.p->length) and
ntohs(pos.p->length) >= sizeof(sctp_paramhdr_t) these two expressions are all true,
pos.v <= (void *)chunk + end - sizeof(sctp_paramhdr_t) *must* be true.

This changes offload setting behaviour to what I think is correct:
 - offloads set via ethtool mean what admin wants to use (by default
   he wants 'em all)
 - offloads set via ioctl() mean what userspace is expecting to get
   (this limits which admin wishes are granted)
 - TUN_NOCHECKSUM is ignored, as it might cause broken packets when
   forwarded (ip_summed == CHECKSUM_UNNECESSARY means that checksum
   was verified, not that it can be ignored)

If TUN_NOCHECKSUM is implemented, it should set skb->csum_* and
skb->ip_summed (= CHECKSUM_PARTIAL) for known protocols and let others
be verified by kernel when necessary.

TUN_NOCHECKSUM handling was introduced by commit
f43798c2:

When processing an ACK for ADD_IP parameter, we only release
the routes on non-active transports.  This can cause a wrong
source address to be used.  We can release the routes and
cause new route lookups and source address selection so that
new addresses can be used as source.  Additionally, we don't need
to lookup routes for all transports at the same time.  We can let
the transmit code path update the cached route when the transport
actually sends something.

When we have have to remove a transport due to ASCONF, we move
the data to a new active path.  This can trigger CACC algorithm
to not mark that data as missing when SACKs arrive.  This is
because the transport passed to the CACC algorithm is the one
this data is sitting on, not the one it was sent on (that one
may be gone).  So, by sending the original transport (even if
it's NULL), we may start marking data as missing.
