tipc: Avoid recomputation of outgoing message length

2011-05-10T20:03:57+00:00

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.

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: Improve accuracy of link transmit queue maximum size statistic

2011-02-23T23:05:15+00:00

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.

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: Combine port structure with tipc_port structure

2011-02-23T23:04:27+00:00

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.

tipc: cleanup various cosmetic whitespace issues

2011-01-01T21:57:56+00:00

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.

tipc: Prune down link-specific debugging code

2011-01-01T21:57:53+00:00

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.

tipc: rename dbg.[ch] to log.[ch]

2011-01-01T21:57:51+00:00

As the first step in removing obsolete debugging code from TIPC the
files that implement TIPC's non-debug-related log buffer subsystem
are renamed to better reflect their true nature.

tipc: Remove obsolete inclusions of header files

2010-12-02T21:34:02+00:00

Gets rid of #include statements that are no longer required as a
result of the merging of obsolete native API header file content
into other TIPC include files.

tipc: cleanup function namespace

2010-10-16T18:13:24+00:00

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.
