Introduce helper macro for_each_cmsghdr as a wrapper of the enumerating
cmsghdr from msghdr, just cleanup.

dccp: Convert DCCP_WARN to net_warn_ratelimited

2014-11-09T02:22:54+00:00

Remove the dependency on the "warning" sysctl (net_msg_warn)
which is only used by the LIMIT_NETDEBUG macro.

Convert the LIMIT_NETDEBUG use in DCCP_WARN to the more
common net_warn_ratelimited mechanism.

This still ratelimits based on the net_ratelimit()
function, but removes the check for the sysctl.

net: Add and use skb_copy_datagram_msg() helper.

2014-11-05T21:46:40+00:00

This encapsulates all of the skb_copy_datagram_iovec() callers
with call argument signature "skb, offset, msghdr->msg_iov, length".

When we move to iov_iters in the networking, the iov_iter object will
sit in the msghdr.

Having a helper like this means there will be less places to touch
during that transformation.

Based upon descriptions and patch from Al Viro.

11) Don't overwrite end of SKB when parsing malformed sctp ASCONF
    chunks, from Daniel Borkmann.

12) Don't call sock_kfree_s() with NULL pointers, this function also has
    the side effect of adjusting the socket memory usage.  From Cong Wang.

ipv6: introduce tcp_v6_iif()

2014-10-18T03:48:07+00:00

Commit 971f10eca186 ("tcp: better TCP_SKB_CB layout to reduce cache line
misses") added a regression for SO_BINDTODEVICE on IPv6.

This is because we still use inet6_iif() which expects that IP6 control
block is still at the beginning of skb->cb[]

This patch adds tcp_v6_iif() helper and uses it where necessary.

Because __inet6_lookup_skb() is used by TCP and DCCP, we add an iif
parameter to it.
