tipc: Enhance cleanup of broadcast link when contact with node is lost · c5bd4d85

由 Allan Stephens 提交于 4月 07, 2011

Enhances cleanup of broadcast link-related information when contact
with a node is lost.

1) All broadcast link-related cleanup now occurs only if the lost node
   was capable of communicating over the broadcast link.

2) Following cleanup, the lost node is marked as no longer supporting
   the broadcast link, ensuring that any remaining broadcast messages
   received from that node prior to the re-establishment of a normal
   communication link are ignored.

Thanks to Surya [Suryanarayana.Garlapati@emerson.com] for contributing
a prototype version of this patch.

tipc: Remove non-executable code to handle broadcast bearer congestion · 23f0ff90

由 Allan Stephens 提交于 4月 07, 2011

Eliminates code associated with the sending of unsent broadcast link
traffic when the broadcast pseudo-bearer becomes unblocked following a
temporary congestion situation. This code is non-executable because the
broadcast pseudo-bearer never becomes blocked [see tipc_bcbearer_send()].

tipc: Cosmetic changes to broadcast bearer send routine · 2ff9f924

由 Allan Stephens 提交于 4月 07, 2011

Updates the comments in the broadcast bearer send routine to more
accurately describe the processing done by the routine. Also replaces
the improper use of a TIPC payload message error status symbol (in a place
that has nothing to do with such errors) with its numeric equivalent.

tipc: Update obsolete references to multicast link · 2e2d9be8

由 Allan Stephens 提交于 4月 07, 2011

Updates TIPC's broadcast link in a couple of places that were missed
during the transition from its former name ("multicast-link") to its
current name ("broadcast-link"). These changes are essentially cosmetic
and do not affect the overall operation of TIPC.

tipc: Enhance filtering of out-dated link reset messages · 641c218d

由 Allan Stephens 提交于 4月 07, 2011

Ensure TIPC ignores an out-dated link reset message whose session
number predates the current session number. (Previously, TIPC only
ignored an out-date reset message whose session number was equal
to the current link session number.)

Out-dated link reset messages should not occur under normal circumstances;
however, they can be generated if a link endpoint is unable to send a
link reset message right away and queues it for later delivery, but the
queued message is not sent until after the link is established.

Thanks to Laser [gotolaser@gmail.com] for diagnosing the problem and
contributing a prototype patch.

tipc: Initialize peer session field of newly created link endpoint · f882cb76

由 Allan Stephens 提交于 4月 07, 2011

Initializes the peer session number field of a newly created link
endpoint to an invalid value. This eliminates the remote possibility
that it will accidentally match the session number used by the peer
the first time the link is activated, and cause the link to ignore
a valid RESET message.

tipc: Display meaningful peer interface name during link creation · 062b4c99

由 Allan Stephens 提交于 4月 07, 2011

Sets the peer interface portion of the name of a newly created link
endpoint to "unknown". This ensures that state and statistics information
can be properly displayed during the time between the link endpoint's
creation and the time handshaking with its peer is completed.

tipc: Eliminate obsolete filter for unexpected unicast messages · ed33a9c4

由 Allan Stephens 提交于 4月 05, 2011

Removes a test that ensures unicast link endpoints discard an incoming
message if it will not be consumed by the node itself and cannot be
forwarded to another node, since the preceding test already ensures that
the message is destined for this node and single-cluster TIPC no longer
performs message forwarding.

tipc: Remove obsolete manipulation of message re-route count field · 5adeb17c

由 Allan Stephens 提交于 4月 05, 2011

Eliminates code that increments and validates the re-route count field
of payload messages, since the elimination of multi-cluster support
means that it is no longer necessary for TIPC to forward incoming messages
to another node. (The obsolete code was incorrect anyway, since it
incorrectly incremented the re-route count field of messages that
originated on the node that forwarded the message.)
