  • f905730c7   tipc: Allow use of buf_seqno() helper routine by unicast links ... Browse Code »

    Migrates the buf_seqno() helper routine from broadcast link level to
    unicast link level so that it can be used both types of TIPC links.
    This is a cosmetic change only, and does not affect the operation of TIPC.

  • 365595914   tipc: Ignore broadcast acknowledgements that are out-of-range ... Browse Code »

    Adds checks to TIPC's broadcast link so that it ignores any
    acknowledgement message containing a sequence number that does not
    correspond to an unacknowledged message currently in the broadcast
    link's transmit queue.

    This change prevents the broadcast link from becoming stalled if a
    newly booted node receives stale broadcast link acknowledgement
    information from another node that has not yet fully synchronized
    its end of the broadcast link to reflect the current state of the
    new node's end.

  • 9aa88c2a5   tipc: Enhance sending of bulk name table messages ... Browse Code »

    Modifies the initial transfer of name table entries to a new neighboring
    node so that the messages are enqueued as a unit, rather than individually.

    The revised algorithm now locates the link carrying the message only once,
    and eliminates unnecessary checks for link congestion, message fragmentation,
    and message bundling that are not required when sending these messages.

  • 268969046   tipc: Avoid recomputation of outgoing message length ... Browse Code »

    Rework TIPC's message sending routines to take advantage of the total
    amount of data value passed to it by the kernel socket infrastructure.
    This change eliminates the need for TIPC to compute the size of outgoing
    messages itself, as well as the check for an oversize message in
    tipc_msg_build(). In addition, this change warrants an explanation:

    - res = send_packet(NULL, sock, &my_msg, 0);
    + res = send_packet(NULL, sock, &my_msg, bytes_to_send);

    Previously, the final argument to send_packet() was ignored (since the
    amount of data being sent was recalculated by a lower-level routine)
    and we could just pass in a dummy value (0). Now that the
    recalculation is being eliminated, the argument value being passed to
    send_packet() is significant and we have to supply the actual amount
    of data we want to send.

  • 37b9c08a8   tipc: Optimizations to link creation code ... Browse Code »

    Enhances link creation code as follows:

    1) Detects illegal attempts to add a requested link earlier in the
    link creation process. This prevents TIPC from wasting time
    initializing a link object it then throws away, and also eliminates
    the code needed to do the throwing away.

    2) Passes in the node object associated with the requested link.
    This allows TIPC to eliminate a search to locate the node object,
    as well as code that attempted to create the node if it doesn't
    exist.

  • 9bd80b608   tipc: Improve accuracy of link transmit queue maximum size statistic ... Browse Code »

    Enhances TIPC's unicast and broadcast link code to update the transmit
    queue maximum size counter in a single place, namely the routine that
    adds messages to the queue. This ensures that the maximum size statistic
    reported for unicast links is completely accurate, rather than being
    partially based on statistical sampling.

    The changes to link.h are just documenting the roles of the variables.

  • 2d627b92f   tipc: Combine bearer structure with tipc_bearer structure ... Browse Code »

    Combines two distinct structures containing information about a TIPC bearer
    into a single structure. The structures were previously kept separate so
    that public information about a bearer could be made available to plug-in
    media types using TIPC's native API, while the remaining information was
    kept private for use by TIPC itself. However, now that the native API has
    been removed there is no longer any need for this arrangement.

    Since one of the structures was already embedded within the other, the
    change largely involves replacing instances of "publ.foo" with "foo".
    The changes do not otherwise alter the operation of TIPC bearers.

    Merge two distinct structures containing information about a TIPC port
    into a single structure. The structures were previously kept separate
    so that public information about a port could be made available to
    applications using TIPC's native API, while the remaining information
    was kept private for use by TIPC itself. However, now that the native
    API has been removed there is no longer any need for this somewhat
    confusing arrangement.

    Since one of the structures was already embedded within the other, the
    change largely involves replacing instances of "publ.foo" with "foo".
    The changes do not otherwise alter the operation of TIPC ports.

  • 0e65967e3   tipc: cleanup various cosmetic whitespace issues ... Browse Code »

    Cleans up TIPC's source code to eliminate deviations from generally
    accepted coding conventions relating to leading/trailing white space
    and white space around commas, braces, cases, and sizeof.

    These changes are purely cosmetic and do not alter the operation of TIPC
    in any way.

  • 8d64a5ba5   tipc: Prune down link-specific debugging code ... Browse Code »

    Eliminates most link-specific debugging code in TIPC, which is now
    largely unnecessary. All calls to the link-specific debugging macros
    have been removed, as are the macros themselves; in addition, the optional
    allocation of print buffers to hold debugging information for each link
    endpoint has been removed. The ability for TIPC to print out helpful
    diagnostic information when link retransmit failures occur has been
    retained for the time being, as an aid in tracking down the cause of
    such failures.

    Do some cleanups of TIPC based on make namespacecheck
    1. Don't export unused symbols
    2. Eliminate dead code
    3. Make functions and variables local
    4. Rename buf_acquire to tipc_buf_acquire since it is used in several files

    Compile tested only.
    This make break out of tree kernel modules that depend on TIPC routines.

    Remove all instances of legacy, or as yet to be implemented code
    that is currently living within an #if 0 ... #endif block.
    In the rare instance that some of it be needed in the future,
    it can still be dragged out of history, but there is no need
    for it to sit in mainline.
