transport/socket: use appropriate address family macro when address family is inet-sdp.

2010-01-22T13:34:35+00:00

- sa_family should be set to AF_INET_SDP only during call to socket system
    call. For all other calls, sa_family should be AF_INET.

transport/ib-verbs: fix race-condition resulting in freeing of transport while it was still being used.

2009-11-16T08:41:36+00:00

- while handling a failed work completion status, the transport is
    disconnected. But further down in the code, the transport is still
    used. There can be a possibility that transport might've been freed
    by the time control reaches this point. More detailed description of
    events leading to this situation can be found at

transport/ib-verbs: synchronize ib_verbs_recv_completion_proc with ib_verbs_receive so that the former doesn't overwrite the pointer from which latter reads.

2009-11-16T08:41:32+00:00

- There can be a condition wherein,
    1. the thread executing ib_verbs_recv_completion_proc (thr 1) stores the
       buffer pointer and notifies the upper translators about a POLLIN event.
    2. the thread waiting for events on socket (thr 2) calls transport_receive,
       but in ib_verbs_receive it has not still read the data.
    3. thr 1 receives work completion event for another work request and
       overwrites the buffer pointer.
    4. thr 2 reads from the new pointer there by missing the data stored in
       buffer pointed by pointer which got overwritten.

transport/name.c: refine the address resolution logic when listen-host is not specified.

2009-11-03T14:48:58+00:00

- when listen-host is not specified and there are are no interfaces having
    adresses belonging to the address-family specified, listen at 0.0.0.0/::0.

  - this patch is necessary since with AI_ADDRCONFIG, getaddrinfo fails if there
    are no active interfaces for the address family specified and when
    listen-host is specified we still want the functionality provided with
    usage of AI_ADDRCONFIG.
