Hi David,
Two things. 1. Which kernel version are you using?
2. Not sure if debian has dynamic_printk enabled, I guess so.
Please run this command to turn on some debug printk's, which should
get activated in the case the asoc is not found.
As root:
# echo 'func __sctp_rcv_lookup +p' > /sys/kernel/debug/dynamic_debug/control
And then reproduce the issue again. If you get a printk on dmesg, it's
because the association is not being located when the packet came in,
and thus why the Abort.
This message is available on kernel >= 4.11.
M.
