Two special cases here - one is rxrpc - I put init_net there
explicitly, since we haven't touched this part yet. The second
place is in __udp4_lib_rcv - we already have a struct net there,
but I have to move its initialization above to make it ready
at the "drop" label.Signed-off-by: Pavel Emelyanov

This counter is about to become per-proto-and-per-net, so we'll need
two arguments to determine which cell in this "table" to work with.All the places, but proc already pass proper net to it - proc will be
tuned a bit later.Some indentation with spaces in proc files is done to keep the file
coding style consistent.Signed-off-by: Pavel Emelyanov

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.Signed-off-by: Pavel Emelyanov

1) Cleanups (all functions are prefixed by sock_prot_inuse)
sock_prot_inc_use(prot) -> sock_prot_inuse_add(prot,-1)
sock_prot_dec_use(prot) -> sock_prot_inuse_add(prot,-1)
sock_prot_inuse() -> sock_prot_inuse_get()New functions :
sock_prot_inuse_init() and sock_prot_inuse_free() to abstract pcounter use.
2) if CONFIG_PROC_FS=n, we can zap 'inuse' member from "struct proto",
since nobody wants to read the inuse value.This saves 1372 bytes on i386/SMP and some cpu cycles.

__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

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

This patch consolidates set/getsockopt code between UDP(-Lite) v4 and 6. The
justification is that UDP(-Lite) is a transport-layer protocol and therefore
the socket option code (at least in theory) should be AF-independent.Furthermore, there is the following code reduplication:
* do_udp{,v6}_getsockopt is 100% identical between v4 and v6
* do_udp{,v6}_setsockopt is identical up to the following differerence
--v4 in contrast to v4 additionally allows the experimental encapsulation
types UDP_ENCAP_ESPINUDP and UDP_ENCAP_ESPINUDP_NON_IKE
--the remainder is identical between v4 and v6
I believe that this difference is of little relevance.The advantages in not duplicating twice almost completely identical code.
The patch further simplifies the interface of udp{,v6}_push_pending_frames,
since for the second argument (struct udp_sock *up) it always holds that
up = udp_sk(sk); where sk is the first function argument.Signed-off-by: Gerrit 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

This also kills a warning while building ipv6:

This patch creates one common function which is called by
udp_v4_get_port() and udp_v6_get_port(). As a result,
* duplicated code is removed
* udp_port_rover and local port lookup can now be removed from udp.h
* further savings follow since the same function will be used by UDP-Litev4
and UDP-Litev6In contrast to the patch sent in response to Yoshifujis comments
(fixed by this variant), the code below also removes the
EXPORT_SYMBOL(udp_port_rover), since udp_port_rover can now remain
local to net/ipv4/udp.c.Signed-off-by: Gerrit Renker

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
