[DCCP]: Allow default/fallback service code.

2006-09-24T20:49:26+00:00

This has been discussed on dccp@vger and removes the necessity for applications
to supply service codes in each and every case.

If an application does not want to provide a service code, that's fine, it will
be given 0. Otherwise, service codes can be set via socket options as before.

This patch has been tested using various client/server configurations
(including listening on multiple service codes).

[DCCP]: Introduce tx buffering

2006-09-22T22:18:17+00:00

This adds transmit buffering to DCCP.

I have tested with CCID2/3 and with loss and rate limiting.

[DCCP] minisock: Rename struct dccp_options to struct dccp_minisock

2006-03-21T06:50:58+00:00

This will later be included in struct dccp_request_sock so that we can
have per connection feature negotiation state while in the 3way
handshake, when we clone the DCCP_ROLE_LISTEN socket (in
dccp_create_openreq_child) we'll just copy this state from
dreq_minisock to dccps_minisock.

Also the feature negotiation and option parsing code will mostly touch
dccps_minisock, which will simplify some stuff.

[DCCP]: Make CCID2 be the default

2006-03-21T03:23:58+00:00

As per the draft. This fixes the build when netfilter dccp components
are built and dccp isn't. Thanks to Reuben Farrelly for reporting
this.

The following changesets will introduce /proc/sys/net/dccp/defaults/
to give more flexibility to DCCP developers and testers while apps
doesn't use setsockopt to specify the desired CCID, etc.

[DCCP]: sparse endianness annotations

2006-03-21T03:23:32+00:00

This also fixes the layout of dccp_hdr short sequence numbers, problem
was not fatal now as we only support long (48 bits) sequence numbers.

[DCCP] CCID: Improve CCID infrastructure

2006-03-21T03:21:44+00:00

1. No need for ->ccid_init nor ->ccid_exit, this is what module_{init,exit}
   does and anynways neither ccid2 nor ccid3 were using it.

2. Rename struct ccid to struct ccid_operations and introduce struct ccid
   with a pointer to ccid_operations and rigth after it the rx or tx
   private state.

3. Remove the pointer to the state of the half connections from struct
   dccp_sock, now its derived thru ccid_priv() from the ccid pointer.

Now we also can implement the setsockopt for changing the CCID easily as
no ccid init routines can affect struct dccp_sock in any way that prevents
other CCIDs from working if a CCID switch operation is asked by apps.

[DCCP]: Set the default CCID according to kernel config selection

2006-03-21T01:56:56+00:00

Now CCID2 is the default, as stated in the RFC drafts, but we allow
a config where just CCID3 is built, where CCID3 becomes the default.

[DCCP]: Initial feature negotiation implementation

2006-03-21T01:43:56+00:00

Still needs more work, but boots and doesn't crashes, even
does some negotiation!
