Subject: [PATCH 5/8] trace-cmd record: Prevent memory leak in setup_network()
|
|
|
|
Because of the again label, msg_handle can be already allocated if we
|
|
exit after we got a negative socket file descriptor. Free it there.
|
|
Also unassign msg_handle->fd as to not double close sfd.
|
|
|
|
Fixes a RESOURCE_LEAK error (CWE-772)
