2009-11-06net: drop capability from protocol definitionsEric Paris1-1/+0
struct can_proto had a capability field which wasn't ever used. It is dropped entirely. struct inet_protosw had a capability field which can be more clearly expressed in the code by just checking if sock->type = SOCK_RAW.

2009-10-19inet: rename some inet_sock fieldsEric Dumazet1-15/+15
In order to have better cache layouts of struct sock (separate zones for rx/tx paths), we need this preliminary patch. Goal is to transfert fields used at lookup time in the first read-mostly cache line (inside struct sock_common) and move sk_refcnt to a separate cache line (only written by rx path) This patch adds inet_ prefix to daddr, rcv_saddr, dport, num, saddr, sport and id fields. This allows a future patch to define these fields as macros, like sk_refcnt, without name clashes. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

2009-10-15net: sk_drops consolidationEric Dumazet1-2/+1
sock_queue_rcv_skb() can update sk_drops itself, removing need for callers to take care of it. This is more consistent since sock_queue_rcv_skb() also reads sk_drops when queueing a skb. This adds sk_drops managment to many protocols that not cared yet. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-10-13net: Generalize socket rx gap / receive queue overflow cmsgNeil Horman1-1/+1
Create a new socket level option to report number of queue overflows Recently I augmented the AF_PACKET protocol to report the number of frames lost on the socket receive queue between any two enqueued frames. This value was exported via a SOL_PACKET level cmsg. AFter I completed that work it was requested that this feature be generalized so that any datagram oriented socket could make use of this option. As such I've created this patch, It creates a new SOL_SOCKET level option called SO_RXQ_OVFL, which when enabled exports a SOL_SOCKET level cmsg that reports the nubmer of times the sk_receive_queue overflowed between any two given frames. It also augments the AF_PACKET protocol to take advantage of this new feature (as it previously did not touch sk->sk_drops, which this patch uses to record the overflow count). Tested successfully by me. Notes: 1) Unlike my previous patch, this patch simply records the sk_drops value, which is not a number of drops between packets, but rather a total number of drops. Deltas must be computed in user space. 2) While this patch currently works with datagram oriented protocols, it will also be accepted by non-datagram oriented protocols. I'm not sure if thats agreeable to everyone, but my argument in favor of doing so is that, for those protocols which aren't applicable to this option, sk_drops will always be zero, and reporting no drops on a receive queue that isn't used for those non-participating protocols seems reasonable to me. This also saves us having to code in a per-protocol opt in mechanism. 3) This applies cleanly to net-next assuming that commit 977750076d98c7ff6cbda51858bb5a5894a9d9ab (my af packet cmsg patch) is reverted Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

2009-09-03ip: Report qdisc packet dropsEric Dumazet1-1/+3
Christoph Lameter pointed out that packet drops at qdisc level where not accounted in SNMP counters. Only if application sets IP_RECVERR, drops are reported to user (-ENOBUFS errors) and SNMP counters updated. IP_RECVERR is used to enable extended reliable error message passing, but these are not needed to update system wide SNMP stats. This patch changes things a bit to allow SNMP counters to be updated, regardless of IP_RECVERR being set or not on the socket. Example after an UDP tx flood # netstat -s ... IP: 1487048 outgoing packets dropped ... Udp: ... SndbufErrors: 1487048 send() syscalls, do however still return an OK status, to not break applications. Note : send() manual page explicitly says for -ENOBUFS error : "The output queue for a network interface was full. This generally indicates that the interface has stopped sending, but may be caused by transient congestion. (Normally, this does not occur in Linux. Packets are just silently dropped when a device queue overflows.) " This is not true for IP_RECVERR enabled sockets : a send() syscall that hit a qdisc drop returns an ENOBUFS error.

2008-06-13ipv6: Fix duplicate initialization of rawv6_prot.destroyDavid S. Miller1-2/+2
In changeset 22dd485022f3d0b162ceb5e67d85de7c3806aa20 ("raw: Raw socket leak.") code was added so that we flush pending frames on raw sockets to avoid leaks. The ipv4 part was fine, but the ipv6 part was not done correctly. Unlike the ipv4 side, the ipv6 code already has a .destroy method for rawv6_prot. So now there were two assignments to this member, and what the compiler does is use the last one, effectively making the ipv6 parts of that changeset a NOP. Fix this by removing the: .destroy = inet6_destroy_sock, line, and adding an inet6_destroy_sock() call to the end of raw6_destroy(). Noticed by Al Viro. Signed-off-by: David S.

2008-04-12[IPv6]: Change IPv6 unspecified destination address to ::1 for raw and ↵Brian Haley1-10/+4
un-connected sockets This patch fixes a difference between IPv4 and IPv6 when sending packets to the unspecified address (either 0.0.0.0 or ::) when using raw or un-connected UDP sockets. There are two cases where IPv6 either fails to send anything, or sends with the destination address set to ::. For example: --> ping -c1 0.0.0.0 PING 0.0.0.0 (127.0.0.1) 56(84) bytes of data. 64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.032 ms --> ping6 -c1 :: PING ::(::) 56 data bytes ping: sendmsg: Invalid argument Doing a sendto("0.0.0.0") reveals: 10:55:01.495090 IP localhost.32780 > localhost.7639: UDP, length 100 Doing a sendto("::") reveals: 10:56:13.262478 IP6 fe80::217:8ff:fe7d:4718.32779 > ::.7639: UDP, length 100 If you issue a connect() first in the UDP case, it will be sent to ::1, similar to what happens with TCP.
