Right now, any time we set a primary transport we set
the changeover_active flag. As a result, we invoke SFR-CACC
even when there has been no changeover events.
Only set changeover_active, when there is a true changeover
event, i.e. we had a primary path and we are changing to
another transport.

Commit e9df2e8fd8fbc95c57dbd1d33dada66c4627b44c ("[IPV6]: Use
appropriate sock tclass setting for routing lookup.") also changed the
way that ECN capable transports mark this capability in IPv6. As a
result, SCTP was not marking ECN capablity because the traffic class
was never set. This patch brings back the markings for IPv6 traffic.

When fast retransmit is triggered by a sack, we should flush the queue
only once so that only 1 retransmit happens. Also, since we could
potentially have non-fast-rtx chunks on the retransmit queue, we need
make sure any chunks eligable for fast retransmit are sent first
during fast retransmission.

Recently I posted a patch to add some informational items to
/proc/net/sctp/assocs. All the information is correct, but because
of how the seqfile show operation is laid out, some of the formatting
is backwards. This patch corrects that formatting, so that the new
information appears at the end of each line, rather than in the middle.

All IP addresses that are present in a system are duplicated on
struct sctp_sockaddr_entry. They are linked in the global list
called sctp_local_addr_list. And this struct unions IPv4 and IPv6
addresses.
So, there can be rare case, when a sockaddr_in.sin_addr coincides
with the corresponding part of the sockaddr_in6 and the notifier
for IPv4 will carry away an IPv6 entry.
The fix is to check the family before comparing the addresses.

When receiving an error length INIT-ACK during COOKIE-WAIT,
a 0-vtag ABORT will be responsed. This action violates the
protocol apparently. This patch achieves the following things.
1 If the INIT-ACK contains all the fixed parameters, use init-tag
recorded from INIT-ACK as vtag.
2 If the INIT-ACK doesn't contain all the fixed parameters,
just reflect its vtag.

RFC 4890 has the following text:
The HMAC algorithm based on SHA-1 MUST be supported and
included in the HMAC-ALGO parameter.
As a result, we need to check in sctp_verify_param() that HMAC_SHA1 is
present in the list. If not, we should probably treat this as a
protocol violation.
It should also be a protocol violation if the HMAC parameter is empty.

With a was number of callsites sctp_add_cmd_sf wrapper bloats
kernel by some amount. Due to unlikely tracking allyesconfig,
with the initial result were around ~7kB (thus caught my
attention) while a non-debug config produced only ~2.3kB effect.
I (ij) proposed first a patch to uninline it but Vlad responded
with a patch that removed the only sctp_add_cmd call which is
wrapped by sctp_add_cmd_sf (I wasn't sure if I could do that).
I did minor cleanup to Vlad's patch.

There is a race is SCTP between the loading of the module
and the access by the socket layer to the protocol functions.
In particular, a list of addresss that SCTP maintains is
not initialized prior to the registration with the protosw.
Thus it is possible for a user application to gain access
to SCTP functions before everything has been initialized.
The problem shows up as odd crashes during connection
initializtion when we try to access the SCTP address list.
The solution is to refactor how we do registration and
initialize the lists prior to registering with the protosw.
Care must be taken since the address list initialization
depends on some other pieces of SCTP initialization. Also
the clean-up in case of failure now also needs to be refactored.
