[PATCH 6.6 163/530] SUNRPC: ECONNRESET might require a rebind

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

 



6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx>

[ Upstream commit 4b09ca1508a60be30b2e3940264e93d7aeb5c97e ]

If connect() is returning ECONNRESET, it usually means that nothing is
listening on that port. If so, a rebind might be required in order to
obtain the new port on which the RPC service is listening.

Fixes: fd01b2597941 ("SUNRPC: ECONNREFUSED should cause a rebind.")
