udp: multicast packets need to check namespace

2008-12-13T23:29:12Z

[ Upstream commit 920a46115ca3fa88990276d98520abab85495b2d ] Current UDP multicast delivery is not namespace aware. Signed-off-by: Eric Dumazet Acked-by: Pavel Emelyanov Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

udp: Drop socket lock for encapsulated packets

2008-08-09T07:35:05Z

The socket lock is there to protect the normal UDP receive path. Encapsulation UDP sockets don't need that protection. In fact the locking is deadly for them as they may contain another UDP packet within, possibly with the same addresses. Also the nested bit was copied from TCP. TCP needs it because of accept(2) spawning sockets. This simply doesn't apply to UDP so I've removed it. Signed-off-by: Herbert Xu Signed-off-by: David S. Miller

udp: sk_drops handling

2008-06-18T04:04:56Z

In commits 33c732c36169d7022ad7d6eb474b0c9be43a2dc1 ([IPV4]: Add raw drops counter) and a92aa318b4b369091fd80433c80e62838db8bc1c ([IPV6]: Add raw drops counter), Wang Chen added raw drops counter for /proc/net/raw & /proc/net/raw6 This patch adds this capability to UDP sockets too (/proc/net/udp & /proc/net/udp6). This means that 'RcvbufErrors' errors found in /proc/net/snmp can be also be examined for each udp socket. # grep Udp: /proc/net/snmp Udp: InDatagrams NoPorts InErrors OutDatagrams RcvbufErrors SndbufErrors Udp: 23971006 75 899420 16390693 146348 0 # cat /proc/net/udp sl local_address rem_address st tx_queue rx_queue tr tm->when retrnsmt --- uid timeout inode ref pointer drops 75: 00000000:02CB 00000000:0000 07 00000000:00000000 00:00000000 00000000 --- 0 0 2358 2 ffff81082a538c80 0 111: 00000000:006F 00000000:0000 07 00000000:00000000 00:00000000 00000000 --- 0 0 2286 2 ffff81042dd35c80 146348 In this example, only port 111 (0x006F) was flooded by messages that user program could not read fast enough. 146348 messages were lost.

udp: add struct net argument to udp_hashfn

2008-06-17T00:12:29Z

Every caller already has this one. The new argument is currently unused, but this will be fixed shortly. Signed-off-by: Pavel Emelyanov Signed-off-by: David S. Miller

udp: provide a struct net pointer for __udp[46]_lib_mcast_deliver

2008-06-17T00:12:11Z

They both calculate the hash chain, but currently do not have a struct net pointer, so pass one there via additional argument, all the more so their callers already have such. Signed-off-by: Pavel Emelyanov Signed-off-by: David S. Miller

udp: introduce a udp_hashfn function

2008-06-17T00:11:50Z

Currently the chain to store a UDP socket is calculated with simple (x & (UDP_HTABLE_SIZE - 1)). But taking net into account would make this calculation a bit more complex, so moving it into a function would help. Signed-off-by: Pavel Emelyanov Signed-off-by: David S. Miller
