    [NET]: Supporting UDP-Lite (RFC 3828) in Linux · ba4e58ec
    Gerrit Renker authored
    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)
