sctp: fix error cause codes of ADD-IP extension

2009-06-03T13:14:45+00:00

RFC5061 had changed the error cause codes for Dynamic Address
Reconfiguration As the following:

       Cause Code
       Value          Cause Code
       ---------      ----------------
       0x00A0          Request to Delete Last Remaining IP Address
       0x00A1          Operation Refused Due to Resource Shortage
       0x00A2          Request to Delete Source IP Address
       0x00A3          Association Aborted Due to Illegal ASCONF-ACK
       0x00A4          Request Refused - No Authorization

This patch fix the error cause codes.

sctp: Clean up sctp checksumming code

2009-02-16T08:03:10+00:00

The sctp crc32c checksum is always generated in little endian.
So, we clean up the code to treat it as little endian and remove
all the __force casts.

Suggested by Herbert Xu.

net: replace __constant_{endian} uses in net headers

2009-02-15T06:58:35+00:00

Base versions handle constant folding now.  For headers exposed to
userspace, we must only expose the __ prefixed versions.

[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.

[SCTP]: Implement the Supported Extensions Parameter

2007-10-10T23:51:23+00:00

SCTP Supported Extenions parameter is specified in Section 4.2.7
of the ADD-IP draft (soon to be RFC).  The parameter is
encoded as:

      0                   1                   2                   3
      0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
     +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
     |     Parameter Type = 0x8008   |      Parameter Length         |
     +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
     | CHUNK TYPE 1  |  CHUNK TYPE 2 |  CHUNK TYPE 3 |  CHUNK TYPE 4 |
     +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
     |                             ....                              |
     +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
     | CHUNK TYPE N  |      PAD      |      PAD      |      PAD      |
     +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

It contains a list of chunks that a particular SCTP extension
uses.  Current extensions supported are Partial Reliability
(FWD-TSN) and ADD-IP (ASCONF and ASCONF-ACK).

When implementing new extensions (AUTH, PKT-DROP, etc..), new
chunks need to be added to this parameter.  Parameter processing
would be modified to negotiate support for these new features.

[SK_BUFF]: Introduce skb_transport_header(skb)

2007-04-26T05:25:31+00:00

For the places where we need a pointer to the transport header, it is
still legal to touch skb->h.raw directly if just adding to,
subtracting from or setting it to another layer header.
