* ethtool: Add a common function for drivers with transmit time stamping.Richard Cochran2012-04-04
| | | | | | | | | | Currently, most drivers do not support transmit SO_TIMESTAMPING. For those that do support it, there is one appropriate response to the get_ts_info query. This patch adds a common function providing this response. Signed-off-by: Richard Cochran <richardcochran@gmail.com> Reviewed-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

* ethtool: Introduce a method for getting time stamping capabilities.Richard Cochran2012-04-04
| | | | | | | | | | | | | | | This commit adds a new ethtool ioctl that exposes the SO_TIMESTAMPING capabilities of a network interface. In addition, user space programs can use this ioctl to discover the PTP Hardware Clock (PHC) device associated with the interface. Since software receive time stamps are handled by the stack, the generic ethtool code can answer the query correctly in case the MAC or PHY drivers lack special time stamping features.

* ipv6: Fix 'inet6_rtm_getroute' to release 'rt->dst' in case of 'alloc_skb' ↵Shmulik Ladkani2012-04-04
| | | | | | | | | | | | | | | failure In 72331bc [ipv6: Fix RTM_GETROUTE's interpretation of RTA_IIF to be consistent with ipv4] the code of 'inet6_rtm_getroute()' was re-ordered such that the reference to 'rt->dst' is incremented prior skb allocation. Hence, if 'alloc_skb()' fails, must drop a reference from 'rt->dst'. Add the missing 'dst_release()' call. Signed-off-by: Shmulik Ladkani <shmulik.ladkani@gmail.com> Signed-off-by: David S.

* af_unix: reduce high order page allocationsEric Dumazet2012-04-03
| | | | | | | | | | | | | | | | | | | | | | | | | unix_dgram_sendmsg() currently builds linear skbs, and this can stress page allocator with high order page allocations. When memory gets fragmented, this can eventually fail. We can try to use order-2 allocations for skb head (SKB_MAX_ALLOC) plus up to 16 page fragments to lower pressure on buddy allocator. This patch has no effect on messages of less than 16064 bytes. (on 64bit arches with PAGE_SIZE=4096) For bigger messages (from 16065 to 81600 bytes), this patch brings reliability at the expense of performance penalty because of extra pages allocations. netperf -t DG_STREAM -T 0,2 -- -m 16064 -s 200000 ->4086040 Messages / 10s netperf -t DG_STREAM -T 0,2 -- -m 16068 -s 200000 ->3901747 Messages / 10s Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

* net: Report dev->promiscuity in netlink reports.Ben Greear2012-04-02
| | | | | | | | | | | The standard ways of probing a device's promiscuity (ifi_flags, for instance) does not report the actual state of the device. This patch adds dev->promiscuity to the netlink netdevice report so that users can know for certain if the device is acting PROMISC or not.
