net: build_ehash_secret() and rt_bind_peer() cleanups

2010-08-20T07:50:16Z

Now cmpxchg() is available on all arches, we can use it in build_ehash_secret() and rt_bind_peer() instead of using spinlocks. Signed-off-by: Eric Dumazet CC: Mathieu Desnoyers Signed-off-by: David S. Miller

inet, inet6: make tcp_sendmsg() and tcp_sendpage() through inet_sendmsg() and inet_sendpage()

2010-07-13T03:21:46Z

a new boolean flag no_autobind is added to structure proto to avoid the autobind calls when the protocol is TCP. Then sock_rps_record_flow() is called int the TCP's sendmsg() and sendpage() pathes.

snmp: 64bit ipstats_mib for all arches

2010-06-30T20:31:19Z

/proc/net/snmp and /proc/net/netstat expose SNMP counters. Width of these counters is either 32 or 64 bits, depending on the size of "unsigned long" in kernel. This means user program parsing these files must already be prepared to deal with 64bit values, regardless of user program being 32 or 64 bit. This patch introduces 64bit snmp values for IPSTAT mib, where some counters can wrap pretty fast if they are 32bit wide. # netstat -s|egrep "InOctets|OutOctets" InOctets: 244068329096 OutOctets: 244069348848 Signed-off-by: Eric Dumazet Signed-off-by: David S.

snmp: add align parameter to snmp_mib_init()

2010-06-26T04:33:17Z

In preparation for 64bit snmp counters for some mibs, add an 'align' parameter to snmp_mib_init(), instead of assuming mibs only contain 'unsigned long' fields. Callers can use __alignof__(type) to provide correct alignment. Signed-off-by: Eric Dumazet CC: Herbert Xu CC: Arnaldo Carvalho de Melo CC: Hideaki YOSHIFUJI CC: Vlad Yasevich Signed-off-by: David S.

net - IP_NODEFRAG option for IPv4 socket

2010-06-23T20:16:38Z

this patch is implementing IP_NODEFRAG option for IPv4 socket. The reason is, there's no other way to send out the packet with user customized header of the reassembly part. Signed-off-by: Jiri Olsa Signed-off-by: David S. Miller

net-next: remove useless union keyword

2010-06-11T06:31:35Z

remove useless union keyword in rtable, rt6_info and dn_route. Since there is only one member in a union, the union keyword isn't useful. Signed-off-by: Changli Gao Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

net: reserve ports for applications using fixed port numbers

2010-05-16T06:28:40Z

(Dropped the infiniband part, because Tetsuo modified the related code, I will send a separate patch for it once this is accepted.) This patch introduces /proc/sys/net/ipv4/ip_local_reserved_ports which allows users to reserve ports for third-party applications. The reserved ports will not be used by automatic port assignments (e.g. when calling connect() or bind() with port number 0). Explicit port allocation behavior is unchanged.

net: Make RFS socket operations not be inet specific.

2010-04-27T22:11:48Z

Idea from Eric Dumazet. As for placement inside of struct sock, I tried to choose a place that otherwise has a 32-bit hole on 64-bit systems. Signed-off-by: David S. Miller Acked-by: Eric Dumazet

net: Fix various endianness glitches

2010-04-21T02:06:52Z

Sparse can help us find endianness bugs, but we need to make some cleanups to be able to more easily spot real bugs. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

net: sk_sleep() helper

2010-04-20T23:37:13Z

Define a new function to return the waitqueue of a "struct sock". static inline wait_queue_head_t *sk_sleep(struct sock *sk) { return sk->sk_sleep; } Change all read occurrences of sk_sleep by a call to this function. Needed for a future RCU conversion. sk_sleep wont be a field directly available. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller
