can: gw: Properly fill the netlink header when responding to RTM_GETROUTE

2012-07-10T20:36:01+00:00

 - set message type to RTM_NEWROUTE
 - relate to original request by inheriting the sequence and port number.
 - set NLM_F_MULTI because it's a dump and more messages will follow

can: gw: Use nla_policy to validate netlink attributes

2012-07-10T20:35:41+00:00

Also use nla_get_u32() instead of nla_memcpy() to access u32 attribtues.

can: fix sparse warning in af_can.c

2012-07-02T09:07:27+00:00

Put can_rx_alldev_list into the af_can header to fix the following
sparse warning: net/can/af_can.c:80:22: warning: symbol
'can_rx_alldev_list' was not declared. Should it be static?

Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

2012-06-15T22:51:55+00:00

Conflicts:
	net/ipv6/route.c

This deals with a merge conflict between the net-next addition of the
inetpeer network namespace ops, and Thomas Graf's bug fix in
2a0c451ade8e1783c5d453948289e4a978d417c9 which makes sure we don't
register /proc/net/ipv6_route before it is actually safe to do so.

net: remove skb_orphan_try()

2012-06-15T22:30:15+00:00

Orphaning skb in dev_hard_start_xmit() makes bonding behavior
unfriendly for applications sending big UDP bursts : Once packets
pass the bonding device and come to real device, they might hit a full
qdisc and be dropped. Without orphaning, the sender is automatically
throttled because sk->sk_wmemalloc reaches sk->sk_sndbuf (assuming
sk_sndbuf is not too big)

We could try to defer the orphaning adding another test in
dev_hard_start_xmit(), but all this seems of little gain,
now that BQL tends to make packets more likely to be parked
in Qdisc queues instead of NIC TX ring, in cases where performance
matters.

Reverts commits :
fc6055a5ba31 net: Introduce skb_orphan_try()
87fd308cfc6b net: skb_tx_hash() fix relative to skb_orphan_try()
and removes SKBTX_DRV_NEEDS_SK_REF flag
