    tipc: correct initial value for group congestion flag · 1b22bcad
    Jon Maloy authored
    In commit 60c25306 ("tipc: fix race between poll() and
    setsockopt()") we introduced a pointer from struct tipc_group to the
    'group_is_connected' flag in struct tipc_sock, so that this field can
    be checked without dereferencing the group pointer of the latter struct.
    
    The initial value for this flag is correctly set to 'false' when a
    group is created, but we miss the case when no group is created at
    all, in which case the initial value should be 'true'. This has the
    effect that SOCK_RDM/DGRAM sockets sending datagrams never receive
    POLLOUT if they request so.
    
    This commit corrects this bug.
