Currently if equal-cost multipath is enabled the kernel chooses between
equal cost paths for each matching packet, essentially packets are
round-robined between the routes. This means that packets from a single

When running a Windows 2012 R2 guest with a pair of VFs assigned

if the PF is unbound from the driver while VFs are active. In the
case of igb, the resulting

Upon receipt of SYNACK from the server, ipt_SYNPROXY first sends back an ACK to
finish the server handshake, then calls nf_ct_seqadj_init() to initiate
sequence number adjustment of forwarded packets to the client and finally sends
a window update to the client to unblock it's TX queue.
Since synp
We recently changed this from nf_conntrack_alloc() to nf_ct_tmpl_alloc()

When synproxy_send_server_ack() calls synproxy_send_tcp(), it passes
NULL as third parameter (struct nf_conntrack *nfct). And the first thing
synproxy_send_tcp() does, is dereference it:

sure, and rds does this in rds_tcp_accept_one() too.

The intent of the VRF device is to leverage the existing SO_BINDTODEVICE
as a means of creating L3 domains. Since sockets are expected to be bound
to the VRF device the index of the master device needs to be used for
socket lookups.
