2006-12-02[DCCP] ccid3: Avoid congestion control on zero-sized data packetsGerrit Renker
This resolves an `XXX' in ccid3_hc_tx_send_packet(). The function is only called on Data and DataAck packets and returns a negative result on zero-sized messages. This is a reasonable policy since CCID 3 is a congestion-control module and congestion control on zero-sized Data(Ack) packets is in a way pathological. The patch uses a more suitable error code for this case, it returns the Posix.1 code `EBADMSG' ("Not a data message") instead of `ENOTCONN'. As a result of ignoring zero-sized packets, a the condition for a warning "First packet is data" in ccid3_hc_tx_packet_sent is always satisfied; this message has been removed since it will always be printed.

2006-12-02[DCCP] ccid3: Simplify control flow in the calculation of t_ipiGerrit Renker
This patch performs a simplifying (performance) optimisation: In each call of the inline function ccid3_calc_new_t_ipi(), the state is tested against TFRC_SSTATE_NO_FBACK. This is expensive when the function is called very often. A simpler solution, implemented by this patch, is to adapt the control flow. Background:

2006-12-02[DCCP] ackvec: infrastructure for sending more than one ackvec per packetAndrea Bittau
Commiter note: This was split from Andrea's original patch, in the process I changed the type of the ackvec index fields to u16 instead of to int and haven't folded dccp_ackvec_parse with dccp_ackvec_check_rcv_ackno. Next patch will actually do the insertion of more than one ackvec per packet, using, initially, up to a max of 2 ackvecs as per Andrea's original patch, then I'll work on support for larger ackvecs, be it using a sysctl or using setsockopt.

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]: Add CCID3 debug support to KconfigGerrit Renker
This adds a CCID3 debug option to the configuration menu which is missing in Kconfig, but already used by the code. CCID 2 already provides such an entry. To enable debugging, set CONFIG_IP_DCCP_CCID3_DEBUG=y NOTE: The use of ccid3_{t,r}x_state_name is safe, since now only enum values can appear.

2006-12-02[DCCP] ACKVEC: Optimization - Do not traverse records if none will be foundAndrea Bittau
Do not traverse the list of ack vector records [proportional to window size] when we know we will not find what we are looking for. This is especially useful because ack vectors are checked twice: 1) Upon parsing of options. 2) Upon notification of a new ack. All of the work will occur during check #1. Therefore, when check #2 is performed, no new work will be done. This is now "detected" and there is no performance hit when doing #2.

2006-12-02[DCCPv6]: Resolve conditional build problemGerrit Renker
Resolves the problem that if IPv6 was configured `y' and DCCP `m' then dccp_ipv6 was not built as a module. With this change, dccp_ipv6 is built as a module whenever DCCP *OR* IPv6 are configured as modules; it will be built-in only if both DCCP = `y' and IPV6 = `y'.

2006-12-02[TCP/DCCP]: Introduce net_xmit_evalGerrit Renker
Throughout the TCP/DCCP (and tunnelling) code, it often happens that the return code of a transmit function needs to be tested against NET_XMIT_CN which is a value that does not indicate a strict error condition. This patch uses a macro for these recurring situations which is consistent with the already existing macro net_xmit_errno, saving on duplicated code.

2006-12-02[DCCP]: Remove redundant statements in init_sequence (ISS)Gerrit Renker
This patch removes the following redundancies: 1) The test skb->protocol == htons(ETH_P_IPV6) in dccp_v6_init_sequence is always true since * dccp_v6_conn_request() is the only calling function * dccp_v6_conn_request() redirects all skb's with ETH_P_IP to dccp_v4_conn_request() 2) The first argument, `struct sock *sk', of dccp_v{4,6}_init_sequence() is never used. (This is similar for tcp_v{4,6}_init_sequence, an analogous patch has been submitted to netdev and merged.) By the way - are the `sport' / `dport' arguments in the right order? I have made them consistent among calls but they seem to be in the reverse order. Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com>

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]: Add sysctls to control retransmission behaviourGerrit Renker
This adds 3 sysctls which govern the retransmission behaviour of DCCP control packets (3way handshake, feature negotiation). It removes 4 FIXMEs from the code. The close resemblance of sysctl variables to their TCP analogues is emphasised not only by their name, but also by giving them the same initial values. This is useful since there is not much practical experience with DCCP yet. Furthermore, with regard to the previous patch, it is now possible to limit the number of keepalive-Responses by setting net.dccp.default.request_retries (also a bit like in TCP). Lastly, added documentation of all existing DCCP sysctls. Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com>

2006-12-02[DCCP]: Update comments on precisely which packets can be retransmittedGerrit Renker
This updates program documentation: spell out precise conditions about which packets are eligible for retransmission (which is actually quite hard to extract from RFC 4340). It is based on the following table derived from RFC 4340: +-----------+---------------------------------+---------------------+ | Type | Retransmit? | Remark | +-----------+---------------------------------+---------------------+ | Request | in client-REQUEST state | sec. 8.1.1 | | Response | NEVER | SHOULD NOT, 8.1.3 | | Data | NEVER | unreliable protocol | | Ack | possible in client-PARTOPEN | sec. 8.1.5 | | DataAck | NEVER | unreliable protocol | | CloseReq | only in server-CLOSEREQ state | MUST, sec. 8.3 | | Close | in node-CLOSING state | MUST, sec. 8.3 | +-----------+-------------------------------------------------------+ | Reset | only in response to other packets | | Sync | only in response to sequence-invalid packets (7.5.4) | | SyncAck | only in response to Sync packets | +-----------+-------------------------------------------------------+ Hence the only packets eligible for retransmission are: * Requests in client-REQUEST state (sec. 8.1.1) * Acks in client-PARTOPEN state (sec. 8.1.5) * CloseReq in server-CLOSEREQ state (sec. 8.3) * Close in node-CLOSING state (sec. 8.3) I had meant to put in a check for these types too, but have left that for later.

2006-12-02[DCCP]: Support for partial checksums (RFC 4340, sec. 9.2)Gerrit Renker
This patch does the following: a) introduces variable-length checksums as specified in [RFC 4340, sec. 9.2] b) provides necessary socket options and documentation as to how to use them c) basic support and infrastructure for the Minimum Checksum Coverage feature [RFC 4340, sec. 9.2.1]: acceptability tests, user notification and user interface In addition, it (1) fixes two bugs in the DCCPv4 checksum computation: * pseudo-header used checksum_len instead of skb->len * incorrect checksum coverage calculation based on dccph_x (2) removes dccp_v4_verify_checksum() since it reduplicates code of the checksum computation; code calling this function is updated accordingly. (3) now uses skb_checksum(), which is safer than checksum_partial() if the sk_buff has is a non-linear buffer (has pages attached to it). (4) fixes an outstanding TODO item: * If P.CsCov is too large for the packet size, drop packet and return. The code has been tested with applications, the latest version of tcpdump now comes with support for partial DCCP checksums.
