udp: Generalize skb_udp_segment skb_udp_segment is the function called from udp4_ufo_fragment to segment a UDP tunnel packet. This function currently assumes segmentation is transparent Ethernet bridging (i.e. VXLAN encapsulation). This patch generalizes the function to operate on either Ethertype or IP protocol. The inner_protocol field must be set to the protocol of the inner header. This can now be either an Ethertype or an IP protocol (in a union). A new flag in the skbuff indicates which type is effective. skb_set_inner_protocol and skb_set_inner_ipproto helper functions were added to set the inner_protocol. These functions are called from the point where the tunnel encapsulation is occuring. When skb_udp_tunnel_segment is called, the function to segment the inner packet is selected based on the inner IP or Ethertype. In the case of an IP protocol encapsulation, the function is derived from inet[6]_offloads. In the case of Ethertype, skb->protocol is set to the inner_protocol and skb_mac_gso_segment is called. (GRE currently does this, but it might be possible to lookup the protocol in offload_base and call the appropriate segmenation function directly).

udp: Add function to make source port for UDP tunnels This patch adds udp_flow_src_port function which is intended to be a common function that UDP tunnel implementations call to set the source port. The source port is chosen so that a hash over the outer headers (IP addresses and UDP ports) acts as suitable hash for the flow of the encapsulated packet. In this manner, UDP encapsulation works with RSS and ECMP based wrt the inner flow. Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

udp: ipv4: Add udp early demux The removal of the routing cache introduced a performance regression for some UDP workloads since a dst lookup must be done for each packet. This change caches the dst per socket in a similar manner to what we do for TCP by implementing early_demux. For UDP multicast we can only cache the dst if there is only one receiving socket on the host. Since caching only works when there is one receiving socket we do the multicast socket lookup using RCU. For UDP unicast we only demux sockets with an exact match in order to not break forwarding setups. Additionally since the hash chains may be long we only check the first socket to see if it is a match and not waste extra time searching the whole chain when we might not find an exact match.

Idea of this patch came after Simon Horman proposal to add a hook on TCP as well. If static_key is not yet enabled, the fast path does a single JMP . When static_key is enabled, JMP destination is patched to reach the real encap_type/encap_rcv logic, possibly adding cache misses.

udp: add rehash on connect() commit 30fff923 introduced in linux-2.6.33 (udp: bind() optimisation) added a secondary hash on UDP, hashed on (local addr, local port). Problem is that following sequence : fd = socket(...) connect(fd, &remote, ...) not only selects remote end point (address and port), but also sets local address, while UDP stack stored in secondary hash table the socket while its local address was INADDR_ANY (or ipv6 equivalent) Sequence is : - autobind() : choose a random local port, insert socket in hash tables [while local address is INADDR_ANY] - connect() : set remote address and port, change local address to IP given by a route lookup. When an incoming UDP frame comes, if more than 10 sockets are found in primary hash table, we switch to secondary table, and fail to find socket because its local address changed. One solution to this problem is to rehash datagram socket if needed. We add a new rehash(struct socket *) method in "struct proto", and implement this method for UDP v4 & v6, using a common helper. This rehashing only takes care of secondary hash table, since primary hash (based on local port only) is not changed.

udp: dynamically size hash tables at boot time UDP_HTABLE_SIZE was initialy defined to 128, which is a bit small for several setups. 4000 active UDP sockets -> 32 sockets per chain in average. An incoming frame has to lookup all sockets to find best match, so long chains hurt latency. Instead of a fixed size hash table that cant be perfect for every needs, let UDP stack choose its table size at boot time like tcp/ip route, using alloc_large_system_hash() helper Add an optional boot parameter, uhash_entries=x so that an admin can force a size between 256 and 65536 if needed, like thash_entries and rhash_entries. dmesg logs two new lines : [ 0.647039] UDP hash table entries: 512 (order: 0, 4096 bytes) [ 0.647099] UDP Lite hash table entries: 512 (order: 0, 4096 bytes) Maximal size on 64bit arches would be 65536 slots, ie 1 MBytes for non debugging spinlocks.

udp: introduce struct udp_table and multiple spinlocks UDP sockets are hashed in a 128 slots hash table. This hash table is protected by *one* rwlock. This rwlock is readlocked each time an incoming UDP message is handled. This rwlock is writelocked each time a socket must be inserted in hash table (bind time), or deleted from this table (close time) This is not scalable on SMP machines : 1) Even in read mode, lock() and unlock() are atomic operations and must dirty a contended cache line, shared by all cpus. 2) A writer might be starved if many readers are 'in flight'. This can happen on a machine with some NIC receiving many UDP messages. User process can be delayed a long time at socket creation/dismantle time. This patch prepares RCU migration, by introducing 'struct udp_table and struct udp_hslot', and using one spinlock per chain, to reduce contention on central rwlock. Introducing one spinlock per chain reduces latencies, for port randomization on heavily loaded UDP servers. This also speedup bindings to specific ports. udp_lib_unhash() was uninlined, becoming to big. Some cleanups were done to ease review of following patch (RCUification of UDP Unicast lookups) Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S. Miller <davem@davemloft.net>

[UDP]: Clean up UDP-Lite receive checksum 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.

[UDP(-Lite)]: consolidate v4 and v6 get|setsockopt code 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.

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.

[UDP]: saddr_cmp function should take const socket pointers This also kills a warning while building ipv6: net/ipv6/udp.c: In function ‘udp_v6_get_port’: net/ipv6/udp.c:66: warning: passing argument 3 of ‘udp_get_port’ from incompatible pointer type Signed-off-by: David S.

[UDP]: Unify UDPv4 and UDPv6 ->get_port() 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-Litev6 In 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.

[INET_SOCK]: Move struct inet_sock & helper functions to net/inet_sock.h To help in reducing the number of include dependencies, several files were touched as they were getting needed headers indirectly for stuff they use. Thanks also to Alan Menegotto for pointing out that net/dccp/proto.c had linux/dccp.h include twice. Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S.

Linux-2.6.12-rc2 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!
