2008-04-13T01:40:06+00:00

Fix 3 warnings about discarding const qualifiers:

net/sctp/ulpevent.c:862: warning: passing argument 1 of 'sctp_event2skb' discards qualifiers from pointer target type
net/sctp/sm_statefuns.c:4393: warning: passing argument 1 of 'SCTP_ASOC' discards qualifiers from pointer target type
net/sctp/socket.c:5874: warning: passing argument 1 of 'cmsg_nxthdr' discards qualifiers from pointer target type

[SCTP]: Update AUTH structures to match declarations in draft-16.

2008-02-28T21:45:04+00:00

The new SCTP socket api (draft 16) updates the AUTH API structures.
We never exported these since we knew they would change.
Update the rest to match the draft.

[SCTP]: Incorrect length was used in SCTP_*_AUTH_CHUNKS socket option

2008-02-28T21:45:01+00:00

The chunks are stored inside a parameter structure in the kernel
and when we copy them to the user, we need to account for
the parameter header.

[SCTP]: Pick up an orphaned sctp_sockets_allocated counter.

2008-02-20T08:23:01+00:00

This counter is currently write-only.

Drawing an analogy with the similar tcp counter, I think
that this one should be pointed by the sockets_allocated
members of sctp_prot and sctpv6_prot.

[SCTP]: Set ports in every address returned by sctp_getladdrs()

2008-02-07T02:27:39+00:00

Thomas Dreibholz has reported that port numbers are not filled
in the results of sctp_getladdrs() when the socket was bound
to an ephemeral port.  This is only true, if the address was
not specified either.  So, fill in the port number correctly.

[SCTP]: Do not increase rwnd when reading partial notification.

2008-02-05T15:59:30+00:00

When a user reads a partial notification message, do not
update rwnd since notifications must not be counted towards
receive window.

[SCTP]: Stop claiming that this is a "reference implementation"

2008-02-05T15:59:07+00:00

I was notified by Randy Stewart that lksctp claims to be
"the reference implementation".  First of all, "the
refrence implementation" was the original implementation
of SCTP in usersapce written ty Randy and a few others.
Second, after looking at the definiton of 'reference implementation',
we don't really meet the requirements.

[NET] CORE: Introducing new memory accounting interface.

2008-01-28T23:00:18+00:00

This patch introduces new memory accounting functions for each network
protocol. Most of them are renamed from memory accounting functions
for stream protocols. At the same time, some stream memory accounting
functions are removed since other functions do same thing.

Renaming:
	sk_stream_free_skb()		->	sk_wmem_free_skb()
	__sk_stream_mem_reclaim()	->	__sk_mem_reclaim()
	sk_stream_mem_reclaim()		->	sk_mem_reclaim()
	sk_stream_mem_schedule 		->    	__sk_mem_schedule()
	sk_stream_pages()      		->	sk_mem_pages()
	sk_stream_rmem_schedule()	->	sk_rmem_schedule()
	sk_stream_wmem_schedule()	->	sk_wmem_schedule()
	sk_charge_skb()			->	sk_mem_charge()

Removeing
	sk_stream_rfree():	consolidates into sock_rfree()
	sk_stream_set_owner_r(): consolidates into skb_set_owner_r()
	sk_stream_mem_schedule()

The following functions are added.
    	sk_has_account(): check if the protocol supports accounting
	sk_mem_uncharge(): do the opposite of sk_mem_charge()

In addition, to achieve consolidation, updating sk_wmem_queued is
removed from sk_mem_charge().

Next, to consolidate memory accounting functions, this patch adds
memory accounting calls to network core functions. Moreover, present
memory accounting call is renamed to new accounting call.

Finally we replace present memory accounting calls with new interface
in TCP and SCTP.
