Subject: [PATCH] socket: don't attempt to reconnect a TCP socket in server
|
|
mode
|
|
|
|
Commit c3767ed0eb5d0bb25fe409ae5dec06e3411ff1b6 introduced a possible SEGV when
|
|
using a socket chardev with server=on because it assumes that all TCP sockets
|
|
are in client mode.
|
|
|
|
This patch adds a check to only reconnect when in client mode.
