Allan Stephens 50d3e6399a tipc: Correct misnamed references to neighbor discovery domain
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 <Z.C.N>-type network addresses).
This change is purely cosmetic, and does not affect the operation of TIPC.

Allan Stephens f831c963b5 tipc: Eliminate configuration for maximum number of cluster nodes
Gets rid of the need for users to specify the maximum number of
cluster nodes supported by TIPC. TIPC now automatically provides
support for all 4K nodes allowed by its addressing scheme.

Note: This change sets TIPC's memory usage to the amount used by
a maximum size node table with 4K entries.  An upcoming patch that
converts the node table from a linear array to a hash table will
compact the node table to a more efficient design, but for clarity
it is nice to have all the Kconfig infrastruture go away separately.

Allan Stephens 77c81e0bb8 tipc: Clean out all remaining instances of #if 0'd unused code
Remove all instances of legacy or proposed-but-not-implemented code
that lives within an #if 0 ... #endif block.  If some of it is needed
in the future it can recovered out of history, but there is no need
for it to clutter up the active code base.

Allan Stephens 5413b4c6c0 tipc: Improve handling of invalid link tolerance values
Enhances TIPC link code to ignore an invalid link tolerance value
contained in an incoming LINK_PROTOCOL message, rather than
processing the value and potentially causing a divide-by-zero error.

Also add a compile-time check that catches attempts to redefine
TIPC's minimum link tolerance value in a manner that might result
in the same divide-by-zero error at run-time.

Allan Stephens 0e65967e33 tipc: cleanup various cosmetic whitespace issues
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.

Allan Stephens 8f92df6ad4 tipc: Remove prototype code for supporting multiple clusters
Eliminates routines, data structures, and files that were intended
to allow TIPC to support a network containing multiple clusters.
Currently, TIPC supports only networks consisting of a single cluster
within a single zone, so this code is unnecessary.

Allan Stephens 08c80e9a03 tipc: Remove prototype code for supporting slave nodes
Simplifies routines and data structures that were intended to allow
TIPC to support slave nodes (i.e. nodes that did not have links to
all of the other nodes in its cluster, forcing TIPC to route messages
that it could not deliver directly through a non-slave node).

Currently, TIPC supports only networks containing non-slave nodes,
so this code is unnecessary.

Note: The latest edition of the TIPC 2.0 Specification has eliminated
the concept of slave nodes entirely.

Allan Stephens 59f0c4523f tipc: Fix skb_under_panic when configuring TIPC without privileges
This patch prevents a TIPC configuration command requiring network
administrator privileges from triggering an skbuff underrun if it
is issued by a process lacking those privileges.  The revised error
handling code avoids the use of a potentially uninitialized global
variable by transforming the unauthorized command into a new command,
then following the standard command processing path to generate the
required error message.

Per Liden 16cb4b333c [TIPC] Updated link priority macros
Added macros for min/default/max link priority in tipc_config.h.
Also renamed TIPC_NUM_LINK_PRI to TIPC_MEDIA_LINK_PRI since that
is a more accurate description of what it is used for.
