If ip_vs_conn_fill_param_persist return an error to ip_vs_sched_persist, this error must propagate as ignored=-1 to ip_vs_schedule(). Errors from ip_vs_conn_new() in ip_vs_sched_persist() and ip_vs_schedule() should also return *ignored=-1; This patch just relies on the fact that ignored is 1 before calling ip_vs_sched_persist(). Sent from Julian: "The new case when ip_vs_conn_fill_param_persist fails should set *ignored = -1, so that we can use NF_DROP, see below. *ignored = -1 should be also used for ip_vs_conn_new failure in ip_vs_sched_persist() and ip_vs_schedule(). The new negative value should be handled in tcp,udp,sctp" "To summarize: - *ignored = 1: protocol tried to schedule (eg. on SYN), found svc but the svc/scheduler decides that this packet should be accepted with NF_ACCEPT because it must not be scheduled. - *ignored = 0: scheduler can not find destination, so try bypass or return ICMP and then NF_DROP (ip_vs_leave). - *ignored = -1: scheduler tried to schedule but fatal error occurred, eg. ip_vs_conn_new failure (ENOMEM) or ip_vs_sip_fill_param failure such as missing Call-ID, ENOMEM on skb_linearize or pe_data. In this case we should return NF_DROP without any attempts to send ICMP with ip_vs_leave."

Avoid sending invalid pointer due to skb_linearize() call. This patch prepares for next patch where skb_linearize is a part. In ip_vs_sched_persist() params the ports ptr will be replaced by src and dst port. Signed-off-by:

One struct will have fwmark added: * ip_vs_conn ip_vs_conn_new() and ip_vs_find_dest() will have an extra param - fwmark The effects of that, is in this patch. Signed-off-by:

Only match persistence engine data if it was created by the same persistence engine. Reported-by:
-
Simon Horman authored
The dest of a connection may not exist if it has been created as the result of connection synchronisation. But in order for connection entries for templates with persistence engine data created through connection synchronisation to be valid access to the persistence engine pointer is required. So add the persistence engine to the connection itself. Signed-off-by: -

I am observing consistent behavior even with bridges, so let's unlock this. xt_mac is already usable in FORWARD, too. Section 9 of http://ebtables.sourceforge.net/br_fw_ia/br_fw_ia.html#section9 says the MAC source address is changed, but my observation does not match that claim -- the MAC header is retained.

ct->proto is big(60 bytes) due to structure ip_ct_tcp, and we don't need to initialize the whole for all the other protocols. This patch moves proto to the end of structure nf_conn, and pushes the initialization down to the individual protocols. Signed-off-by:

It seems idev field in struct rtable has no special purpose, but adding extra atomic ops. We hold refcounts on the device itself (using percpu data, so pretty cheap in current kernel). infiniband case is solved using dst.dev instead of idev->dev Removal of this field means routing without route cache is now using shared data, percpu data, and only potential contention is a pair of atomic ops on struct neighbour per forwarded packet. About 5% speedup on routing test. Signed-off-by:

It is important to move nud_state outside of the often modified cache line (because of refcnt), to reduce false sharing in neigh_event_send() This is a followup of commit 0ed8ddf4 (neigh: Protect neigh->ha[] with a seqlock) This gives a 7% speedup on routing test with IP route cache disabled.

The values used to determined if the adapter is running in single or multi-function mode were previously modified to the values necessary when making the VXGE_HW_FW_API_GET_FUNC_MODE firmware call. However, the firmware call was not modified. This had the driver printing out on probe that the adapter was in multi-function mode when in single function mode and vice versa. Signed-off-by:
