sctp: check src addr when processing SACK to update transport state

2012-10-04T19:53:48+00:00

Suppose we have an SCTP connection with two paths. After connection is
established, path1 is not available, thus this path is marked as inactive. Then
traffic goes through path2, but for some reasons packets are delayed (after
rto.max). Because packets are delayed, the retransmit mechanism will switch
again to path1. At this time, we receive a delayed SACK from path2. When we
update the state of the path in sctp_check_transmitted(), we do not take into
account the source address of the SACK, hence we update the wrong path.

sctp: fix a compile error in sctp.h

2012-08-15T10:43:43+00:00

I got the following compile error:

This patch could fix it.

sctp: Push struct net down into sctp_verify_ext_param

2012-08-15T06:30:37+00:00

Add struct net as a parameter to sctp_verify_param so it can be passed
to sctp_verify_ext_param where struct net will be needed when the sctp
tunables become per net tunables.

Add struct net as a parameter to sctp_verify_init so struct net can be
passed to sctp_verify_param.

sctp: Push struct net down into all of the state machine functions

2012-08-15T06:30:37+00:00

There are a handle of state machine functions primarily those dealing
with processing INIT packets where there is neither a valid endpoint nor
a valid assoication from which to derive a struct net.  Therefore add
struct net * to the parameter list of sctp_state_fn_t and update all of
the state machine functions.

sctp: Push struct net down to sctp_chunk_event_lookup

2012-08-15T06:30:37+00:00

This trickles up through sctp_sm_lookup_event up to sctp_do_sm
and up further into sctp_primitiv_NAME before the code reaches
places where struct net can be reliably found.

Start with an empty sctp_net_table that will be populated as the various
tunable sysctls are made per net.
