2008-03-04[UDP]: Allow users to configure UDP-Lite.YOSHIFUJI Hideaki
Let's give users an option for disabling UDP-Lite (~4K). old: | text data bss dec hex filename | 286498 12432 6072 305002 4a76a net/ipv4/built-in.o | 193830 8192 3204 205226 321aa net/ipv6/ipv6.o new (without UDP-Lite): | text data bss dec hex filename | 284086 12136 5432 301654 49a56 net/ipv4/built-in.o | 191835 7832 3076 202743 317f7 net/ipv6/ipv6.o Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org>
2008-01-28[UDP]: Restore missing inDatagrams incrementsHerbert Xu
The previous move of the the UDP inDatagrams counter caused the counting of encapsulated packets, SUNRPC data (as opposed to call) packets and RXRPC packets to go missing. This patch restores all of these. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-06-07[UDP]: Revert 2-pass hashing changes.David S. Miller
This reverts changesets: 6aaf47fa48d3c44280810b1b470261d340e4ed87 b7b5f487ab39bc10ed0694af35651a03d9cb97ff de34ed91c4ffa4727964a832c46e624dd1495cf5 fc038410b4b1643766f8033f4940bcdb1dace633 There are still some correctness issues recently discovered which do not have a known fix that doesn't involve doing a full hash table scan on port bind. So revert for now. Signed-off-by: David S. Miller <davem@davemloft.net>
2007-05-10[UDP]: Fix AF-specific references in AF-agnostic code.David S. Miller
__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>

2007-04-25[UDP]: Clean up UDP-Lite receive checksumHerbert Xu
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.

2006-12-02[NET]: Supporting UDP-Lite (RFC 3828) in LinuxGerrit Renker
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.
