sctp: Change sctp to implement csum_levels

2014-08-30T03:41:11+00:00

CHECKSUM_UNNECESSARY may be applied to the SCTP CRC so we need to
appropriate account for this by decrementing csum_level. This is
done by calling __skb_dec_checksum_unnecessary.

net: fix the counter ICMP_MIB_INERRORS/ICMP6_MIB_INERRORS

2014-08-01T05:04:18+00:00

When dealing with ICMPv[46] Error Message, function icmp_socket_deliver()
and icmpv6_notify() do some valid checks on packet's length, but then some
protocols check packet's length redaudantly. So remove those duplicated
statements, and increase counter ICMP_MIB_INERRORS/ICMP6_MIB_INERRORS in
function icmp_socket_deliver() and icmpv6_notify() respectively.

In addition, add missed counter in udp6/udplite6 when socket is NULL.

'break' after return or goto has no effect. Remove it.

v2: make it more readable as suggested by Neil.

ipv6: move ip6_sk_accept_pmtu from generic pmtu update path to ipv6 one

2013-12-22T03:00:59+00:00

In commit 93b36cf3425b9b ("ipv6: support IPV6_PMTU_INTERFACE on sockets")
I made a horrible mistake to add ip6_sk_accept_pmtu to the generic
sctp_icmp_frag_needed path. This results in build warnings if IPv6 is
disabled which were luckily caught by Fengguang's kbuild bot. But it
also leads to a kernel panic IPv4 frag-needed packet is received.
