SCTP does not pick correct source IP when routing from nonlocal interface
Issue
- SCTP does not pick correct source IP when routing from nonlocal interface
- SCTP does not pick the correct source IP address when the source is on a non-local interface to the outgoing route
- The source address used for all communication is the second address of each assoc, even on the wrong interface. The first address is not used.
Environment
- Red Hat Enterprise Linux (RHEL) 7
- Streaming Control Transport Protocol (SCTP)
- Multiple paths and routes to remote destination
### Client Addresses
eth1
10.0.0.4/27 - route to 172.16.0.82 via 10.0.0.1
eth2
10.0.0.36/27 - route to 172.16.0.86 via 10.0.0.33
dummy0
10.0.0.5/27
10.0.0.7/27
10.0.0.37/27
10.0.0.39/27
### First Assoc
ip.addr == 10.0.0.5 && ip.addr == 172.16.0.82 -> Primary Path
ip.addr == 10.0.0.37 && ip.addr == 172.16.0.86 -> Secondary Path
### Second Assoc
ip.addr == 10.0.0.7 && ip.addr == 172.16.0.82 -> Primary Path
ip.addr == 10.0.0.39 && ip.addr == 172.16.0.86 -> Secondary Path
