net: cleanup unsigned to unsigned int

2012-04-15T16:44:40Z

Use of "unsigned int" is preferred to bare "unsigned" in net tree. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

net: get rid of some pointless casts to sockaddr

2012-03-12T02:11:22Z

The following 4 functions: move_addr_to_kernel move_addr_to_user verify_iovec verify_compat_iovec are always effectively called with a sockaddr_storage. Make this explicit by changing their signature. This removes a large number of casts from sockaddr_storage to sockaddr. Signed-off-by: Maciej Żenczykowski Signed-off-by: David S. Miller

net: Add sendmmsg socket system call

2011-05-05T18:10:14Z

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.

net: fix compat_sys_recvmmsg parameter type

2009-12-11T23:07:56Z

compat_sys_recvmmsg has a compat_timespec parameter and not a timespec parameter. This way we also get rid of an odd cast. Cc: Arnaldo Carvalho de Melo Signed-off-by: Heiko Carstens Acked-by: Arnaldo Carvalho de Melo Signed-off-by: David S. Miller

net: Introduce recvmmsg socket syscall

2009-10-13T06:40:10Z

Meaning receive multiple messages, reducing the number of syscalls and net stack entry/exit operations. Next patches will introduce mechanisms where protocols that want to optimize this operation will provide an unlocked_recvmsg operation. This takes into account comments made by: . Paul Moore: sock_recvmsg is called only for the first datagram, sock_recvmsg_nosec is used for the rest. . Caitlin Bestler: recvmmsg now has a struct timespec timeout, that works in the same fashion as the ppoll one. If the underlying protocol returns a datagram with MSG_OOB set, this will make recvmmsg return right away with as many datagrams (+ the OOB one) it has received so far. . Rémi Denis-Courmont & Steven Whitehouse: If we receive N < vlen datagrams and then recvmsg returns an error, recvmmsg will return the successfully received datagrams, store the error and return it in the next call. This paves the way for a subsequent optimization, sk_prot->unlocked_recvmsg, where we will be able to acquire the lock only at batch start and end, not at every underlying recvmsg call.

net: Make setsockopt() optlen be unsigned.

2009-09-30T23:12:20Z

This provides safety against negative optlen at the type level instead of depending upon (sometimes non-trivial) checks against this sprinkled all over the the place, in each and every implementation. Based upon work done by Arjan van de Ven and feedback from Linus Torvalds. Signed-off-by: David S. Miller

net: Use standard structures for generic socket address structures.

2008-07-20T05:35:47Z

Use sockaddr_storage{} for generic socket address storage and ensures proper alignment. Use sockaddr{} for pointers to omit several casts. Signed-off-by: YOSHIFUJI Hideaki Signed-off-by: David S. Miller

net: Add compat support for getsockopt (MCAST_MSFILTER)

2008-04-29T10:23:22Z

This patch adds support for getsockopt for MCAST_MSFILTER for both IPv4 and IPv6. It depends on the previous setsockopt patch, and uses the same method. Signed-off-by: David L Stevens Signed-off-by: YOSHIFUJI Hideaki Signed-off-by: David S. Miller
