From 88428cc4ae7abcc879295fbb19373dd76aad2bdd Mon Sep 17 00:00:00 2001 From: Olga Kornievskaia Date: Tue, 23 Jun 2020 11:24:09 -0400 Subject: [PATCH] SUNRPC dont update timeout value on connection reset Current behaviour: every time a v3 operation is re-sent to the server we update (double) the timeout. There is no distinction between whether or not the previous timer had expired before the re-sent happened. Here's the scenario: 1. Client sends a v3 operation 2. Server RST-s the connection (prior to the timeout) (eg., connection is immediately reset) 3. Client re-sends a v3 operation but the timeout is now 120sec. As a result, an application sees 2mins pause before a retry in case server again does not reply. Where as if a connection reset didn't change the timeout value, the client would have re-tried (the 3rd time) after 60secs.
