[DCCP] minisock: Rename struct dccp_options to struct dccp_minisock 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]: Remove ambiguity in the way before48 is used This removes two ambiguities in employing the new definition of before48, following the analysis on http://www.mail-archive.com/dccp@vger.kernel.org/msg01295.html (1) Updating GSR when P.seqno >= S.SWL With the old definition we did not update when P.seqno and S.SWL are 2^47 apart. To ensure the same behaviour as with the old definition, this is replaced with the equivalent condition dccp_delta_seqno(S.SWL, P.seqno) >= 0 (2) Sending SYNC when P.seqno >= S.OSR Here it is debatable whether the new definition causes an ambiguity: the case is similar to (1); and to have consistency with the case (1), we use the equivalent condition dccp_delta_seqno(S.OSR, P.seqno) >= 0 Detailed Justification

[DCCP]: Simplified conditions due to use of enum:8 states 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.

[DCCP]: Do not process a packet twice when it's not in state DCCP_OPEN. When packets are received, the connection is either in DCCP_OPEN [fast-path] or it isn't. If it's not [e.g. DCCP_PARTOPEN] upper layers will perform sanity checks and parse options. If it is in DCCP_OPEN, dccp_rcv_established() will do it. It is important not to re-parse options in dccp_rcv_established() when it is not called from the fast-path. Else, fore example, the ack vector will be added twice and the CCID will see the packet twice. The solution is to always enfore sanity checks from the upper layers. When packets arrive in the fast-path, sanity checks will be performed before calling dccp_rcv_established(). Note(acme): I rewrote the patch to achieve the same result but keeping dccp_rcv_established with the previous semantics and having it split into __dccp_rcv_established, that doesn't does do any sanity check, code in state != DCCP_OPEN use this lighter version as they already do the sanity checks.

[DCCP] minisock: Rename struct dccp_options to struct dccp_minisock 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]: Revert patch which disables bidirectional mode This reverts an earlier patch which disabled bidirectional mode, meaning that a listening (passive) socket was not allowed to write to the other (active) end of the connection. This mode had been disabled when there were problems with CCID3, but it imposes a constraint on socket programming and thus hinders deployment. A change is included to ignore RX feedback received by the TX CCID3 module. Many thanks to Andre Noll for pointing out this issue.

[DCCP]: Notify CCID only after ACK vectors have been processed. The CCID should be notified of packet reception only when a packet is valid. Therefore, the ACK vector needs to be processed before notifying the CCID. Also, the CCID might need information provided by the ACK vector.

[DCCP]: Revert patch which disables bidirectional mode This reverts an earlier patch which disabled bidirectional mode, meaning that a listening (passive) socket was not allowed to write to the other (active) end of the connection. This mode had been disabled when there were problems with CCID3, but it imposes a constraint on socket programming and thus hinders deployment. A change is included to ignore RX feedback received by the TX CCID3 module. Many thanks to Andre Noll for pointing out this issue.

[DCCP]: Provide function for RTT sampling A recurring problem, in particular in the CCID code, is that RTT samples from packets with timestamp echo and elapsed time options need to be taken. This service is provided via a new function dccp_sample_rtt in this patch. Furthermore, to protect against `insane' RTT samples, the sampled value is bounded between 100 microseconds and 4 seconds - for which u32 is sufficient.
