* [NETNS][UDP-Lite]: Register /proc/net/udplite(6) in a namespace.Pavel Emelyanov2008-03-24
| | | | | | | | UDP-Lite sockets are displayed in another files, rather than UDP ones, so make the present in namespaces as well. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [UDP]: Make full use of proto.h.udp_hash innovation.Pavel Emelyanov2008-03-22
| | | | | | | | | | | | | | After this we have only udp_lib_get_port to get the port and two stubs for ipv4 and ipv6. No difference in udp and udplite except for initialized h.udp_hash member. I tried to find a graceful way to drop the only difference between udp_v4_get_port and udp_v6_get_port (i.e. the rcv_saddr comparison routine), but adding one more callback on the struct proto didn't appear such :( Maybe later.

* [UDP]: Revert udplite and code split.David S. Miller2008-03-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit db1ed684f6c430c4cdad67d058688b8a1b5e607c ("[IPV6] UDP: Rename IPv6 UDP files."), commit 8be8af8fa4405652e6c0797db5465a4be8afb998 ("[IPV4] UDP: Move IPv4-specific bits to other file.") and commit e898d4db2749c6052072e9bc4448e396cbdeb06a ("[UDP]: Allow users to configure UDP-Lite."). First, udplite is of such small cost, and it is a core protocol just like TCP and normal UDP are. We spent enormous amounts of effort to make udplite share as much code with core UDP as possible. All of that work is less valuable if we're just going to slap a config option on udplite support. It is also causing build failures, as reported on linux-next, showing that the changeset was not tested very well. In fact, this is the second build failure resulting from the udplite change. Finally, the config options provided was a bool, instead of a modular option. Meaning the udplite code does not even get build tested by allmodconfig builds, and furthermore the user is not presented with a reasonable modular build option which is particularly needed by distribution vendors.

* [IPV6]: fix section mismatch warningsDaniel Lezcano2008-01-28
| | | | | | | | | | Removed useless and buggy __exit section in the different ipv6 subsystems. Otherwise they will be called inside an init section during rollbacking in case of an error in the protocol initialization. Signed-off-by: Daniel Lezcano <dlezcano@fr.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPV6]: make the protocol initialization to return an error codeDaniel Lezcano2008-01-28
| | | | | | | | | | | | | This patchset makes the different protocols to return an error code, so the af_inet6 module can check the initialization was correct or not. The raw6 was taken into account to be consistent with the rest of the protocols, but the registration is at the same place. Because the raw6 has its own init function, the proto and the ops structure can be moved inside the raw6.c file. Signed-off-by: Daniel Lezcano <dlezcano@fr.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPV6]: Use the {DEFINE|REF}_PROTO_INUSE infrastructureEric Dumazet2007-11-07
| | | | | | | | | | | Trivial patch to make "tcpv6,udpv6,udplitev6,rawv6" protocols uses the fast "inuse sockets" infrastructure Each protocol use then a static percpu var, instead of a dynamic one. This saves some ram and some cpu cycles Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPV6]: Replace sk_buff ** with sk_buff * in input handlersHerbert Xu2007-10-15

So revert for now. Signed-off-by: David S. Miller <davem@davemloft.net>
* [UDP]: Fix AF-specific references in AF-agnostic code.David S. Miller2007-05-11
| | | | | | | | | | | __udp_lib_port_inuse() cannot make direct references to inet_sk(sk)->rcv_saddr as that is ipv4 specific state and this code is used by ipv6 too. Use an operations vector to solve this, and this also paves the way for ipv6 support for non-wild saddr hashing in UDP. Signed-off-by: David S. Miller <davem@davemloft.net>
* [UDP]: Clean up UDP-Lite receive checksumHerbert Xu2007-04-26
| | | | | | | | | | | | | | | | | | | | | | This patch eliminates some duplicate code for the verification of receive checksums between UDP-Lite and UDP. It does this by introducing __skb_checksum_complete_head which is identical to __skb_checksum_complete_head apart from the fact that it takes a length parameter rather than computing the first skb->len bytes. As a result UDP-Lite will be able to use hardware checksum offload for packets which do not use partial coverage checksums. It also means that UDP-Lite loopback no longer does unnecessary checksum verification. If any NICs start support UDP-Lite this would also start working automatically. This patch removes the assumption that msg_flags has MSG_TRUNC clear upon entry in recvmsg. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

* [NET]: Supporting UDP-Lite (RFC 3828) in LinuxGerrit Renker2006-12-03
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.
