2012-04-04filter: add XOR operationJiri Pirko1-0/+4
Add XOR instruction fo BPF machine. Needed for computing packet hashes. Signed-off-by: Jiri Pirko <jpirko@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-04-04filter: Allow to create sk-unattached filtersJiri Pirko1-4/+62
Today, BPF filters are bind to sockets. Since BPF machine becomes handy for other purposes, this patch allows to create unattached filter. Signed-off-by: Jiri Pirko <jpirko@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-04-04af_unix: reduce high order page allocationsEric Dumazet1-3/+12
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.

2012-04-02net: Report dev->promiscuity in netlink reports.Ben Greear1-0/+3
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.

2012-04-02ipv6: Fix RTM_GETROUTE's interpretation of RTA_IIF to be consistent with ipv4Shmulik Ladkani1-7/+27
In IPv4, if an RTA_IIF attribute is specified within an RTM_GETROUTE message, then a route is searched as if a packet was received on the specified 'iif' interface. However in IPv6, RTA_IIF is not interpreted in the same way: 'inet6_rtm_getroute()' always calls 'ip6_route_output()', regardless the RTA_IIF attribute. As a result, in IPv6 there's no way to use RTM_GETROUTE in order to look for a route as if a packet was received on a specific interface. Fix 'inet6_rtm_getroute()' so that RTA_IIF is interpreted as "lookup a route as if a packet was received on the specified interface", similar to IPv4's 'inet_rtm_getroute()' interpretation.
