It will be used by vxlan, and may not be inlined. Cc: Eric Dumazet Signed-off-by: Cong Wang Signed-off-by: David S. Miller

ipv6: Convert use of typedef ctl_table to struct ctl_table

2013-06-20T06:18:07Z

This typedef is unnecessary and should just be removed. Signed-off-by: Joe Perches Signed-off-by: David S. Miller

net: ipv6: Add IPv6 support to the ping socket.

2013-05-26T04:07:49Z

This adds the ability to send ICMPv6 echo requests without a raw socket. The equivalent ability for ICMPv4 was added in 2011. Instead of having separate code paths for IPv4 and IPv6, make most of the code in net/ipv4/ping.c dual-stack and only add a few IPv6-specific bits (like the protocol definition) to a new net/ipv6/ping.c. Hopefully this will reduce divergence and/or duplication of bugs in the future. Caveats: - Setting options via ancillary data (e.g., using IPV6_PKTINFO to specify the outgoing interface) is not yet supported. - There are no separate security settings for IPv4 and IPv6; everything is controlled by /proc/net/ipv4/ping_group_range. - The proc interface does not yet display IPv6 ping sockets properly. Tested with a patched copy of ping6 and using raw socket calls. Compiles and works with all of CONFIG_IPV6={n,m,y}. Signed-off-by: Lorenzo Colitti Signed-off-by: David S. Miller

ipv6: implement RFC3168 5.3 (ecn protection) for ipv6 fragmentation handling

2013-03-24T21:16:30Z

Hello! After patch 1 got accepted to net-next I will also send a patch to netfilter-devel to make the corresponding changes to the netfilter reassembly logic. Thanks, Hannes -- >8 -- [PATCH 2/2] ipv6: implement RFC3168 5.3 (ecn protection) for ipv6 fragmentation handling This patch also ensures that INET_ECN_CE is propagated if one fragment had the codepoint set.

ipv6: introdcue __ipv6_addr_needs_scope_id and ipv6_iface_scope_id helper functions

2013-03-08T17:29:22Z

__ipv6_addr_needs_scope_id checks if an ipv6 address needs to supply a 'sin6_scope_id != 0'. 'sin6_scope_id != 0' was enforced in case of link-local addresses. To support interface-local multicast these checks had to be enhanced and are now consolidated into these new helper functions. v2: a) migrated to struct ipv6_addr_props v3: a) reverted changes for ipv6_addr_props b) test for address type instead of comparing scope v4: a) unchanged Suggested-by: YOSHIFUJI Hideaki Cc: YOSHIFUJI Hideaki Acked-by: YOSHIFUJI Hideaki Signed-off-by: Hannes Frederic Sowa Acked-by: YOSHIFUJI Hideaki Signed-off-by: David S.

ipv6: use a stronger hash for tcp

2013-02-21T23:15:58Z

It looks like its possible to open thousands of TCP IPv6 sessions on a server, all landing in a single slot of TCP hash table. Incoming packets have to lookup sockets in a very long list. We should hash all bits from foreign IPv6 addresses, using a salt and hash mix, not a simple XOR. inet6_ehashfn() can also separately use the ports, instead of xoring them.
