* net: add gro_compute_pseudo functionsTom Herbert2014-08-241-0/+8
| | | | | | | | | Add inet_gro_compute_pseudo and ip6_gro_compute_pseudo. These are the logical equivalents of inet_compute_pseudo and ip6_compute_pseudo for GRO path. The IP header is taken from skb_gro_network_header. Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* udp: Generic functions to set checksumTom Herbert2014-06-041-0/+12
| | | | | | | | | Added udp_set_csum and udp6_set_csum functions to set UDP checksums in packets. These are for simple UDP packets such as those that might be created in UDP tunnels. Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* net: Call skb_checksum_init in IPv6Tom Herbert2014-05-051-0/+7
| | | | | | | Call skb_checksum_init instead of private functions. Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* net: fix build errors if ipv6 is disabledEric Dumazet2013-10-091-0/+2
| | | | | | | | | | CONFIG_IPV6=n is still a valid choice ;) It appears we can remove dead code. Reported-by: Wu Fengguang <fengguang.wu@intel.com> Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* ipv6: make lookups simpler and fasterEric Dumazet2013-10-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TCP listener refactoring, part 4 : To speed up inet lookups, we moved IPv4 addresses from inet to struct sock_common Now is time to do the same for IPv6, because it permits us to have fast lookups for all kind of sockets, including upcoming SYN_RECV. Getting IPv6 addresses in TCP lookups currently requires two extra cache lines, plus a dereference (and memory stall). inet6_sk(sk) does the dereference of inet_sk(__sk)->pinet6 This patch is way bigger than its IPv4 counter part, because for IPv4, we could add aliases (inet_daddr, inet_rcv_saddr), while on IPv6, it's not doable easily. inet6_sk(sk)->daddr becomes sk->sk_v6_daddr inet6_sk(sk)->rcv_saddr becomes sk->sk_v6_rcv_saddr And timewait socket also have tw->tw_v6_daddr & tw->tw_v6_rcv_saddr at the same offset. We get rid of INET6_TW_MATCH() as INET6_MATCH() is now the generic macro. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* ipv6: move csum_ipv6_magic() and udp6_csum_init() into static libraryCong Wang2013-01-081-57/+5
| | | | | | | | | | | As suggested by David, udp6_csum_init() is too big to be inlined, move it to ipv6 static library, net/ipv6/ip6_checksum.c. And the generic csum_ipv6_magic() too. Cc: David S.

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!
