tipc: Add monitoring of number of nodes discovered by bearer

2011-05-10T20:04:01+00:00

Augments TIPC's discovery object to track the number of neighboring nodes
having an active link to the associated bearer.

This means tipc_disc_update_link_req() becomes either one of:

       tipc_disc_add_dest()
or:
       tipc_disc_remove_dest()

depending on the code flow direction of things.

tipc: Enhance handling of discovery object creation failures

2011-05-10T20:03:59+00:00

Modifies bearer creation and deletion code to improve handling of
scenarios when a neighbor discovery object cannot be created. The
creation routine now aborts the creation of a bearer if its discovery
object cannot be created, and deletes the newly created bearer, rather
than failing quietly and leaving an unusable bearer hanging around.

Since the exit via the goto label really isn't a definitive failure
in all cases, relabel it appropriately.

tipc: Strengthen checks for neighboring node discovery

2011-05-10T20:03:55+00:00

Enhances existing checks on the discovery domain associated with a TIPC
bearer. A bearer can no longer be configured to accept links from itself
only (which would be pointless), or to nodes outside its own cluster
(since multi-cluster support has now been removed from TIPC). Also, the
neighbor discovery routine now validates link setup requests against the
configured discovery domain for the bearer, rather than simply ensuring
the requesting node belongs to the node's own cluster.

tipc: Remove bearer flag indicating existence of broadcast address

2011-03-13T20:35:19+00:00

Eliminates the flag in the TIPC bearer structure that indicates if
the bearer supports broadcasting, since the flag is always set to 1
and serves no useful purpose.

tipc: Remove unused field in bearer structure

2011-03-13T20:35:18+00:00

Eliminates a field in TIPC's bearer objects that is set, but never
referenced.

tipc: Correct misnamed references to neighbor discovery domain

2011-03-13T20:35:18+00:00

Renames items that are improperly labelled as "network scope" items
(which are represented by simple integer values) rather than "network
domain" items (which are represented by -type network addresses).
This change is purely cosmetic, and does not affect the operation of TIPC.

tipc: Remove unused message header field for requested number of links

2011-02-23T23:05:22+00:00

Eliminates support for the "number of requested links" field in a neighbor
discovery message. This field was never used and has been removed from
the TIPC 2.0 protocol specification.

tipc: Combine bearer structure with tipc_bearer structure

2011-02-23T23:05:05+00:00

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.

tipc: remove extraneous braces from single statements

2011-01-01T21:57:57+00:00

Cleans up TIPC's source code to eliminate the presence of unnecessary
use of {} around single statements.

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

tipc: remove zeroing assignments to static global variables

2011-01-01T21:57:57+00:00

Cleans up TIPC's source code to eliminate the needless initialization
of static variables to zero.

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