2007-03-06[DCCP]: Set RTO for newly created child socketGerrit Renker
This mirrors a recent change in tcp_open_req_child, whereby the icsk_rto of the newly created child socket was not set (but rather on the parent socket). Same fix for DCCP.

2006-12-02[DCCP]: Simplified conditions due to use of enum:8 statesGerrit Renker
This reaps the benefit of the earlier patch, which changed the type of CCID 3 states to use enums, in that many conditions are now simplified and the number of possible (unexpected) values is greatly reduced. In a few instances, this also allowed to simplify pre-conditions; where care has been taken to retain logical equivalence. [DCCP]: Introduce a consistent BUG/WARN message scheme This refines the existing set of DCCP messages so that * BUG(), BUG_ON(), WARN_ON() have meaningful DCCP-specific counterparts * DCCP_CRIT (for severe warnings) is not rate-limited * DCCP_WARN() is introduced as rate-limited wrapper Using these allows a faster and cleaner transition to their original counterparts once the code has matured into a full DCCP implementation.

2006-12-02[DCCP]: Introduce a consistent naming scheme for sysctlsGerrit Renker
In order to make their function clearer and obtain a consistent naming scheme to identify sysctls, all existing DCCP sysctls have been prefixed with `sysctl_dccp', following the same convention as used by TCP. Feature-specific sysctls retain the `feat' in the middle, although the `default' has been dropped, since it is obvious from use. Also removed a duplicate `dccp_feat_default_sequence_window' in ipv4.c. Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com>

2006-12-02[DCCP]: calling dccp_v{4,6}_reqsk_send_ack is a BUGGerrit Renker
This patch removes two functions, the send_ack functions of request_sock, which are not called/used by the DCCP code. It is correct that these functions are not called, below is a justification why calling these functions (on a passive socket in the LISTEN/RESPOND state) would mean a DCCP protocol violation. A) Background: using request_sock in TCP:

2006-03-20[DCCP] minisock: Rename struct dccp_options to struct dccp_minisockArnaldo Carvalho de Melo
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.

2006-03-20[DCCP] CCID: Improve CCID infrastructureArnaldo Carvalho de Melo
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.

2006-01-03[DCCP]: Prepare the AF agnostic core for the introduction of DCCPv6Arnaldo Carvalho de Melo
Basically exports a similar set of functions as the one exported by the non-AF specific TCP code. In the process moved some non-AF specific code from dccp_v4_connect to dccp_connect_init and moved the checksum verification from dccp_invalid_packet to dccp_v4_rcv, so as to use it in dccp_v6_rcv too.

2005-09-16[DCCP]: Introduce DCCP_SOCKOPT_SERVICEArnaldo Carvalho de Melo
As discussed in the dccp@vger mailing list: Now applications have to use setsockopt(DCCP_SOCKOPT_SERVICE, service[s]), prior to calling listen() and connect(). An array of unsigned ints can be passed meaning that the listening sock accepts connection requests for several services. With this we can ditch struct sockaddr_dccp and use only sockaddr_in (and sockaddr_in6 in the future). Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S.
