* [TCP/DCCP]: Introduce net_xmit_evalGerrit Renker2006-12-029-30/+14
| | | | | | | | | | | | 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.

* [SELinux]: Add support for DCCPJames Morris2006-12-026-8/+103
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements SELinux kernel support for DCCP (http://linux-net.osdl.org/index.php/DCCP), which is similar in operation to TCP in terms of connected state between peers. The SELinux support for DCCP is thus modeled on existing handling of TCP. A new DCCP socket class is introduced, to allow protocol differentation. The permissions for this class inherit all of the socket permissions, as well as the current TCP permissions (node_bind, name_bind etc). IPv4 and IPv6 are supported, although labeled networking is not, at this stage. Patches for SELinux userspace are at: http://people.redhat.com/jmorris/selinux/dccp/user/ I've performed some basic testing, and it seems to be working as expected. Adding policy support is similar to TCP, the only real difference being that it's a different protocol.

* [DCCP]: Remove redundant statements in init_sequence (ISS)Gerrit Renker2006-12-022-17/+8
| | | | | | | | | | | | | | | | | | | | | | | 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?

* [DCCP]: Introduce a consistent naming scheme for sysctlsGerrit Renker2006-12-025-33/+32
| | | | | | | | | | | | | | 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>
* [DCCP]: Add sysctls to control retransmission behaviourGerrit Renker2006-12-027-13/+91
| | | | | | | | | | | | | | | | | | | | 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>

* [DCCP]: Update comments on precisely which packets can be retransmittedGerrit Renker2006-12-021-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [DCCP]: Support for partial checksums (RFC 4340, sec. 9.2)Gerrit Renker2006-12-027-97/+173
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [NET]: Size listen hash tables using backlog hintEric Dumazet2006-12-029-25/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | We currently allocate a fixed size (TCP_SYNQ_HSIZE=512) slots hash table for each LISTEN socket, regardless of various parameters (listen backlog for example) On x86_64, this means order-1 allocations (might fail), even for 'small' sockets, expecting few connections. On the contrary, a huge server wanting a backlog of 50000 is slowed down a bit because of this fixed limit. This patch makes the sizing of listen hash table a dynamic parameter, depending of : - net.core.somaxconn tunable (default is 128) - net.ipv4.tcp_max_syn_backlog tunable (default : 256, 1024 or 128) - backlog value given by user application (2nd parameter of listen()) For large allocations (bigger than PAGE_SIZE), we use vmalloc() instead of kmalloc(). We still limit memory allocation with the two existing tunables (somaxconn & tcp_max_syn_backlog). So for standard setups, this patch actually reduce RAM usage.

The config options in the IPv4/IPv6/DECnet subsystems to enable respectively disable mark based routing only obfuscate the code with ifdefs, the cost for the additional comparison in the flow key is insignificant, and most distributions have all these options enabled by default anyway. Therefore it makes sense to remove the config options and enable mark based routing by default. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
