Subject: [PATCH] trace-cmd: Close socket descriptor on failed connection
Date: Mon, 15 Aug 2022 17:19:47 -0400	[thread overview]
Message-ID: <20220815171947.57e919df@gandalf.local.home> (raw)

From: "Steven Rostedt (Google)" <rostedt@goodmis.org>

In trace_vsock_open(), if the connection fails, the sd file descriptor
still needs to be closed.

Fixes: 76aaeb474 ("trace-cmd: Add VM kernel tracing over vsockets transport")
