* [NET]: Supporting UDP-Lite (RFC 3828) in LinuxGerrit Renker2006-12-0228-403/+1442
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a revision of the previously submitted patch, which alters the way files are organized and compiled in the following manner: * UDP and UDP-Lite now use separate object files * source file dependencies resolved via header files net/ipv{4,6}/udp_impl.h * order of inclusion files in udp.c/udplite.c adapted accordingly [NET/IPv4]: Support for the UDP-Lite protocol (RFC 3828) This patch adds support for UDP-Lite to the IPv4 stack, provided as an extension to the existing UDPv4 code: * generic routines are all located in net/ipv4/udp.c * UDP-Lite specific routines are in net/ipv4/udplite.c * MIB/statistics support in /proc/net/snmp and /proc/net/udplite * shared API with extensions for partial checksum coverage [NET/IPv6]: Extension for UDP-Lite over IPv6 It extends the existing UDPv6 code base with support for UDP-Lite in the same manner as per UDPv4. In particular, * UDPv6 generic and shared code is in net/ipv6/udp.c * UDP-Litev6 specific extensions are in net/ipv6/udplite.c * MIB/statistics support in /proc/net/snmp6 and /proc/net/udplite6 * support for IPV6_ADDRFORM * aligned the coding style of protocol initialisation with af_inet6.c * made the error handling in udpv6_queue_rcv_skb consistent; to return `-1' on error on all error cases * consolidation of shared code [NET]: UDP-Lite Documentation and basic XFRM/Netfilter support The UDP-Lite patch further provides * API documentation for UDP-Lite * basic xfrm support * basic netfilter support for IPv4 and IPv6 (LOG target) Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: David S.

| | | | | | | | | | | By replacing the current method of exporting the device configuration which included allocating a temporary buffer, copying ipv6_devconf into it and copying that buffer into the message with a method that uses nla_reserve() allowing to copy the device configuration directly into the skb data buffer, a GFP_ATOMIC allocation could be removed.

* netpoll header cleanupStephen Hemminger2006-12-021-4/+3
| | | | | | | | As Steve left netpoll beast, hopefully not to return soon. He noticed that the header was messy. He straightened it up and polished it a little, then waved goodbye. Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
* netpoll queue cleanupStephen Hemminger2006-12-023-23/+5
| | | | | | | | | | | | The beast had a long and not very happy history. At one point, a friend (netdump) had asked that he open up a little. Well, the friend was long gone now, and the beast had this dangling piece hanging (netpoll_queue). It wasn't hard to stitch the netpoll_queue back in where it belonged and make everything tidy. Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
* netpoll retry cleanupStephen Hemminger2006-12-022-39/+33
| | | | | | | | | | | | The netpoll beast was still not happy. If the beast got clogged pipes, it tended to stare blankly off in space for a long time. The problem couldn't be completely fixed because the beast talked with irq's disabled. But it could be made less painful and shorter. Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
* netpoll deferred transmit pathStephen Hemminger2006-12-021-2/+19
| | | | | | | | | | | | | When the netpoll beast got busy, he tended to babble. Instead of talking out of his large mouth as normal, he tended to try to snort out other orifices. This lead to words (skbs) ending up in odd places (like NIT) that he did not intend. The normal way of talking wouldn't work, but he could at least change to using the same tone all the time. Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
* netpoll setup error handlingStephen Hemminger2006-12-022-9/+18
| | | | | | | | | The beast was not always healthy. When it was sick, it tended to be laconic and not tell anyone the real problem. A few small changes had it telling the world about its problems, if they really wanted to hear. Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
* netpoll per device txqStephen Hemminger2006-12-022-35/+17
| | | | | | | | | When the netpoll beast got really busy, it tended to clog things, so it stored them for later. But the beast was putting all it's skb's in one basket. This was bad because maybe some pipes were clogged and others were not. Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
* netpoll info leakStephen Hemminger2006-12-022-6/+20
| | | | | | | | | | | | | After looking harder, Steve noticed that the netpoll beast leaked a little every time it shutdown for a nap. Not a big leak, but a nuisance kind of thing. He took out his refcount duct tape and patched the leak. It was overkill since there was already other locking in that area, but it looked clean and wouldn't attract fleas. Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
* netpoll: private skb pool (rev3)Stephen Hemminger2006-12-021-32/+21
| | | | | | | | | | | | | | | | It was a dark and stormy night when Steve first saw the netpoll beast. The beast was odd, and misshapen but not extremely ugly. "Let me take off one of your warts" he said. This wart is where you tried to make an skb list yourself. If the beast had ever run out of memory, he would have stupefied himself unnecessarily. The first try was painful, so he tried again till the bleeding stopped. And again, and again... Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
* [DCCP] ACKVEC: Optimization - Do not traverse records if none will be foundAndrea Bittau2006-12-021-1/+2
| | | | | | | | | | | | | | | | 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.

* [DCCP]: Miscellaneous code tidy-upsGerrit Renker2006-12-027-63/+54
| | | | | | | | | | | | | | | | | | | This patch does not change code; it performs some trivial clean/tidy-ups: * removal of a `debug_prefix' string in favour of the already existing dccp_role(sk) * add documentation of structures and constants * separated out the cases for invalid packets (step 1 of the packet validation) * removing duplicate statements * combining declaration & initialisation Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com>

* [DCCPv6]: Resolve conditional build problemGerrit Renker2006-12-021-4/+4
| | | | | | | | | | 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'.

* [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.
