* [DCCP]: Don't use necessarily the same CCID for tx and rxArnaldo Carvalho de Melo2005-09-181-1/+2

* [DCCP]: Move the ack vector code to net/dccp/ackvec.[ch]Arnaldo Carvalho de Melo2005-09-181-433/+7
| | | | | | | | Isolating it, that will be used when we introduce a CCID2 (TCP-Like) implementation. Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [DCCP] Introduce dccp_timestampArnaldo Carvalho de Melo2005-09-091-10/+35
| | | | | | | | To start the timestamps with 0.0ms, easing the integer maths in the CCIDs, this probably will be reworked to use the to be introduced struct timeval_offset infrastructure out of skb_get_timestamp, etc. Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com>
* [DCCP] Give precedence to the biggest ELAPSED_TIMEArnaldo Carvalho de Melo2005-09-091-16/+18
| | | | | | | | | | | We can get this value in an TIMESTAMP_ECHO and/or in an ELAPSED_TIME option, if receiving both give precendence to the biggest one. In my tests they are very close if not equal at all times, so we may well think about removing the code in CCID3 that inserts this option and leaving this to the core, and perhaps even use just TIMESTAMP_ECHO including the elapsed time.

* [CCID] Only call the HC insert_options methods when requestedArnaldo Carvalho de Melo2005-09-091-3/+8

* [CCID3]: Reorganise timeval handlingArnaldo Carvalho de Melo2005-08-291-2/+3
| | | | | | | | | | | | | | | | | Introducing functions to add to or subtract from a timeval variable and renaming now_delta to timeval_new_delta that calls do_gettimeofday and then timeval_delta, that should be used when there are several deltas made relative to the current time or setting variables to it, so as to avoid calling do_gettimeofday excessively. I'm leaving these "timeval_" prefixed funcions internal to DCCP for a while till we're sure there are no subtle bugs in it. It also is more correct as it checks if the number of usecs added to or subtracted from a tv_usec field is more than 2 seconds.

* [DCCP]: Export dccp_insert_option_timestamp to CCIDsArnaldo Carvalho de Melo2005-08-291-4/+4
| | | | | | | | And don't insert a TIMESTAMP option in all packets, leave the decision to the CCIDs. Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [DCCP]: Fix the timestamp optionsIan McDonald2005-08-291-28/+59
| | | | | | | | | | | | | | | | This changes timestamp, timestamp echo, and elapsed time to use units of 10 usecs as per DCCP spec. This has been tested to verify that times are correct. Also fixed up length and used hton/ntoh more. Still to add in later patches: - actually use elapsed time to adjust RTT (commented out as was prior to this patch) - send options at times more closely following the spec (content is now correct) Signed-off-by: Ian McDonald <iam4@cs.waikato.ac.nz> Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S.

Development to this point was done on a subversion repository at: http://oops.ghostprotocols.net:81/cgi-bin/viewcvs.cgi/dccp-2.6/ This repository will be kept at this site for the foreseable future, so that interested parties can see the history of this code, attributions, etc. If I ever decide to take this offline I'll provide the full history at some other suitable place.
