Subject[PATCH] ipvs: fix synchronization on connection close
Date
commit 9d3a0de makes slaves expire as they would do on the master
with much shorter timeouts. But it introduces another problem:
When we close a connection, on master server the connection became
CLOSE_WAIT/TIME_WAIT, it was synced to slaves, but if master is
finished within it's timeouts (CLOSE), it will not be synced to
slaves. Then slaves will be kept on CLOSE_WAIT/TIME_WAIT until
timeout reaches. Thus we should also sync with CLOSE.
