tipc: Eliminate obsolete routine for handling routed messages

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

Eliminates a routine that is used in handling messages arriving from
another cluster or zone. Such messages can no longer be received by TIPC
now that multi-cluster and multi-zone network support has been eliminated.

tipc: Eliminate remaining support for routing table messages

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

Gets rid of all remaining code relating to ROUTE_DISTRIBUTOR messages.
These messages were only used in multi-cluster and multi-zone networks,
which TIPC no longer supports. (For safety, TIPC now treats such messages
the same way that it handles other unrecognized messages.)

tipc: Optimizations to link creation code

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

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.

tipc: Fix redundant link field handling in link protocol message

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

Ensures that the "redundant link exists" field of the LINK_PROTOCOL
messages sent by a link endpoint is set if and only if the sending
node has at least one other working link to the peer node. Previously,
the bit was set only if there were at least 2 working links to the peer
node, meaning the bit was incorrectly left unset in messages sent by a
non-working link endpoint when exactly one alternate working link was
available. The revised code now takes the state of the link sending
the message into account when deciding if an alternate link exists.

tipc: make msg_set_redundant_link() consistent with other set ops

2011-03-13T20:35:17+00:00

All the other boolean like msg_set_X(m) operations don't
export both a msg_set_X(a) and a msg_clear_X(m), but instead
just have the single msg_set_X(m, val) variant.

Make the redundant_link one consistent by having the set take
a value, and delete the msg_clear_redundant_link() anomoly.
This is a cosmetic change and should not change behaviour.

tipc: cosmetic - function names are not to be full sentences

2011-03-13T20:35:17+00:00

Function names like "tipc_node_has_redundant_links" are unweildy
and result in long lines even for simple lines.  The "has" doesn't
contribute any value add, so dropping that is a slight step in the
right direction.   This is a cosmetic change, basic result of:

for i in `grep -l tipc_node_has_ *` ; do sed -i s/tipc_node_has_/tipc_node_/ $i ; done

tipc: Eliminate timestamp from link protocol messages

2011-03-13T20:35:17+00:00

Removes support for the timestamp field of TIPC's link protocol messages.

This field was previously used to hold an OS-dependent timestamp value
that was used to assist in debugging early versions of TIPC. The field
has now been deemed unnecessary and has been removed from the latest TIPC
specification. This change has no impact on the operation of TIPC since
the field was set by TIPC, but never referenced.

tipc: Add in missing lock during link initialization

2011-02-23T23:05:19+00:00

Ensure that the routine that starts up processing on a newly created
link endpoint takes the spinlock of the node object that owns the link,
to prevent possible conflicts with processing involving other links
owned by that node object.

tipc: Set unused probe field of link protocol messages to defined value

2011-02-23T23:05:16+00:00

Ensures that a link reset or activate message has a "probe" field
of zero. (This field is currently unused in these messages, but this
could potentially change in future versions of TIPC.)
