* [DCCP]: Transition from PARTOPEN to OPEN when receiving DATA packetsArnaldo Carvalho de Melo2005-10-101-1/+5
| | | | | | | | Noticed by Andrea Bittau, that provided a patch that was modified to not transition from RESPOND to OPEN when receiving DATA packets. Signed-off-by: Arnaldo Carvalho de Melo <acme@ghostprotocols.net> Signed-off-by: David S. Miller <davem@davemloft.net>
* [DCCP]: Move the ack vector code to net/dccp/ackvec.[ch]Arnaldo Carvalho de Melo2005-09-181-56/+13
| | | | | | | | 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]: More precisely set reset_code when sending RESET packetsArnaldo Carvalho de Melo2005-09-161-11/+11
| | | | | | | | Moving the setting of DCCP_SKB_CB(skb)->dccpd_reset_code to the places where events happen that trigger sending a RESET packet. Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [DCCP]: Handle SYNC packets in dccp_rcv_state_processArnaldo Carvalho de Melo2005-09-131-0/+6
| | | | | | | Eliciting a SYNCACK in response, we were handling SYNC packets only in the DCCP_OPEN state, in dccp_rcv_established. Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com>
* [DCCP]: Check if already in the CLOSING state in dccp_rcv_closereqArnaldo Carvalho de Melo2005-09-131-1/+2
| | | | | | | | It is possible to receive more than one CLOSEREQ packet if the CLOSE packet sent in response is somehow lost, change the state to DCCP_CLOSING only on the first CLOSEREQ packet received. Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com>
* [DCCP] Introduce dccp_timestampArnaldo Carvalho de Melo2005-09-091-2/+2
| | | | | | | | 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]: Initial dccp_poll implementationArnaldo Carvalho de Melo2005-08-291-0/+1
| | | | | | | Tested with a patched netcat, no horror stories so far 8) Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [DCCP]: Implement the CLOSING timerArnaldo Carvalho de Melo2005-08-291-15/+11
| | | | | | | | | | | So that we retransmit CLOSE/CLOSEREQ packets till they elicit an answer or we hit a timeout. Most of the machinery uses TCP approaches, this code has to be polished & audited, but this is better than we had before.

* [DCCP]: Send SYNCACK packets in response to SYNC packetsArnaldo Carvalho de Melo2005-08-291-8/+25
| | | | | | | | Also fix step 6 when receiving SYNC or SYNCACK packets, i.e. we were not using the updated swl. Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [DCCP]: Fix RESET handling in dccp_rcv_state_processArnaldo Carvalho de Melo2005-08-291-18/+42

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.
