    scsi: iscsi: target: Fix conn_ops double free · 05a86e78
    Mike Christie authored
    If iscsi_login_init_conn fails it can free conn_ops.
    __iscsi_target_login_thread will then call iscsi_target_login_sess_out
    which will also free it.
    
    This fixes the problem by organizing conn allocation/setup into parts that
    are needed through the life of the conn and parts that are only needed for
    the login. The free functions then release what was allocated in the alloc
    functions.
    
    With this patch we have:
    
    iscsit_alloc_conn/iscsit_free_conn - allocs/frees the conn we need for the
    entire life of the conn.
    
    iscsi_login_init_conn/iscsi_target_nego_release - allocs/frees the parts
    of the conn that are only needed during login.
