2007-08-13[DCCP]: fix memory leak and clean up style - dccp_feat_empty_confirm()Jesper Juhl
There's a memory leak in net/dccp/feat.c::dccp_feat_empty_confirm(). If we hit the 'default:' case of the 'switch' statement, then we return without freeing 'opt', thus leaking 'struct dccp_opt_pend' bytes. The leak is fixed easily enough by adding a kfree(opt); before the return statement. The patch also changes the layout of the 'switch' to be more in line with CodingStyle.

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.

2006-03-20[DCCP] feat: Pass dccp_minisock ptr where only the minisock is usedArnaldo Carvalho de Melo
This is in preparation for having a dccp_minisock embedded into dccp_request_sock so that feature negotiation can be done prior to creating the full blown dccp_sock. Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S. Miller <davem@davemloft.net>
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.
