[PATCH 5.4 065/123] netfilter: synproxy: synproxy_cpu_seq_next should increase position index

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Vasily Averin <vvs@xxxxxxxxxxxxx>

commit bb71f846a0002239f7058c84f1496648ff4a5c20 upstream.

If .next function does not change position index,
following .show function will repeat output related
to current position index.
