From 4591bd46e6f8db67b61fdf09ae1bc266d73808ee Mon Sep 17 00:00:00 2001 From: Marc-André Lureau Date: Tue, 17 Jul 2018 14:31:45 +0200 Subject: char-socket: make 'fd' incompatible with 'reconnect' MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A chardev socket created with the 'fd=' argument is not going to handle reconnection properly by recycling the same fd (or not in a supported way). Let's forbid this case. Signed-off-by: Marc-André Lureau Reviewed-by: Daniel P.
