ipv6: unify logic evaluating inet6_dev's accept_ra property

2012-12-01T16:36:37Z

As of 026359b [ipv6: Send ICMPv6 RSes only when RAs are accepted], the logic determining whether to send Router Solicitations is identical to the logic determining whether kernel accepts Router Advertisements. However the condition itself is repeated in several code locations. Unify it by introducing 'ipv6_accept_ra()' accessor. Also, simplify the condition expression, making it more readable. No semantic change. Signed-off-by: Shmulik Ladkani Signed-off-by: David S. Miller

ipv6: improve ipv6_find_hdr() to skip empty routing headers

2012-11-12T20:31:37Z

This patch prepares ipv6_find_hdr() function so that it could be able to skip routing headers, where segements_left is 0. This is required to handle multiple routing header case correctly when changing IPv6 addresses. Signed-off-by: Ansis Atteka Signed-off-by: Jesse Gross

ipv6: Move ipv6_find_hdr() out of Netfilter code.

2012-11-10T01:05:07Z

Open vSwitch will soon also use ipv6_find_hdr() so this moves it out of Netfilter-specific code into a more common location. Signed-off-by: Jesse Gross

ipv6: unify conntrack reassembly expire code with standard one

2012-09-19T21:23:28Z

Two years ago, Shan Wei tried to fix this: http://patchwork.ozlabs.org/patch/43905/ The problem is that RFC2460 requires an ICMP Time Exceeded -- Fragment Reassembly Time Exceeded message should be sent to the source of that fragment, if the defragmentation times out. " If insufficient fragments are received to complete reassembly of a packet within 60 seconds of the reception of the first-arriving fragment of that packet, reassembly of that packet must be abandoned and all the fragments that have been received for that packet must be discarded. If the first fragment (i.e., the one with a Fragment Offset of zero) has been received, an ICMP Time Exceeded -- Fragment Reassembly Time Exceeded message should be sent to the source of that fragment. " As Herbert suggested, we could actually use the standard IPv6 reassembly code which follows RFC2460. With this patch applied, I can see ICMP Time Exceeded sent from the receiver when the sender sent out 3/4 fragmented IPv6 UDP packet.

net ip6 flowlabel: Make owner a union of struct pid * and kuid_t

2012-08-15T04:49:25Z

Correct a long standing omission and use struct pid in the owner field of struct ip6_flowlabel when the share type is IPV6_FL_S_PROCESS. This guarantees we don't have issues when pid wraparound occurs. Use a kuid_t in the owner field of struct ip6_flowlabel when the share type is IPV6_FL_S_USER to add user namespace support. In /proc/net/ip6_flowlabel capture the current pid namespace when opening the file and release the pid namespace when the file is closed ensuring we print the pid owner value that is meaning to the reader of the file. Similarly use from_kuid_munged to print uid values that are meaningful to the reader of the file. This requires exporting pid_nr_ns so that ipv6 can continue to built as a module.

ipv6: add ipv6_addr_hash() helper

2012-07-18T18:28:46Z

Introduce ipv6_addr_hash() helper doing a XOR on all bits of an IPv6 address, with an optimized x86_64 version. Use it in flow dissector, as suggested by Andrew McGregor, to reduce hash collision probabilities in fq_codel (and other users of flow dissector) Use it in ip6_tunnel.c and use more bit shuffling, as suggested by David Laight, as existing hash was ignoring most of them. Use it in sunrpc and use more bit shuffling, using hash_32(). Use it in net/ipv6/addrconf.c, using hash_32() as well. As a cleanup, use it in net/ipv4/tcp_metrics.c Signed-off-by: Eric Dumazet Reported-by: Andrew McGregor Cc: Dave Taht Cc: Tom Herbert Cc: David Laight Cc: Joe Perches Signed-off-by: David S. Miller
