net: recvmmsg: Strip MSG_WAITFORONE when calling recvmsg

2011-05-17T19:38:57+00:00

recvmmsg fails on a raw socket with EINVAL. The reason for this is
packet_recvmsg checks the incoming flags:

        err = -EINVAL;
        if (flags & ~(MSG_PEEK|MSG_DONTWAIT|MSG_TRUNC|MSG_CMSG_COMPAT|MSG_ERRQUEUE))
                goto out;

This patch strips out MSG_WAITFORONE when calling recvmmsg which
fixes the issue.

net,rcu: convert call_rcu(wq_free_rcu) to kfree_rcu()

2011-05-08T05:51:10+00:00

The rcu callback wq_free_rcu() just calls a kfree(),
so we use kfree_rcu() instead of the call_rcu(wq_free_rcu).

net: Add sendmmsg socket system call

2011-05-05T18:10:14+00:00

This patch adds a multiple message send syscall and is the send
version of the existing recvmmsg syscall. This is heavily
based on the patch by Arnaldo that added recvmmsg.

I wrote a microbenchmark to test the performance gains of using
this new syscall:

http://ozlabs.org/~anton/junkcode/sendmmsg_test.c

The test was run on a ppc64 box with a 10 Gbit network card. The
benchmark can send both UDP and RAW ethernet packets.

64B UDP

batch   pkts/sec
1       804570
2       872800 (+ 8 %)
4       916556 (+14 %)
8       939712 (+17 %)
16      952688 (+18 %)
32      956448 (+19 %)
64      964800 (+20 %)

64B raw socket

batch   pkts/sec
1       1201449
2       1350028 (+12 %)
4       1461416 (+22 %)
8       1513080 (+26 %)
16      1541216 (+28 %)
32      1553440 (+29 %)
64      1557888 (+30 %)

We see a 20% improvement in throughput on UDP send and 30%
on raw socket send.

v3 ethtool: add ntuple flow specifier data to network flow classifier

2011-04-11T20:20:49+00:00

This change is meant to add an ntuple data extensions to the rx network flow
classification specifiers.  The idea is to allow ntuple to be displayed via
the network flow classification interface.

The first patch had some left over stuff from the original flow extension
flags I had added.  That bit is removed in this patch.

The second had some left over comments that stated we ignored bits in the
masks when we actually match them.

This work is based on input from Ben Hutchings.

ethtool: Compat handling for struct ethtool_rxnfc

2011-03-18T22:13:11+00:00

This structure was accidentally defined such that its layout can
differ between 32-bit and 64-bit processes.  Add compat structure
definitions and an ioctl wrapper function.

Use __force to quiet sparse warnings for cases where the code
is simulating user space pointers.
