tipc: Fix sk_buff leaks when link congestion is detected

2011-05-10T20:03:53+00:00

Modifies a TIPC send routine that did not discard the outgoing sk_buff
if it was not transmitted because of link congestion; this eliminates
the potential for buffer leakage in the many callers who did not clean up
the unsent buffer. (The two routines that previously did discard the unsent
buffer have been updated to eliminate their now-redundant clean up.)

tipc: Remove code to emulate loss of broadcast messages

2011-05-10T20:03:46+00:00

Eliminates optional code used to test TIPC's ability to recover
from lost broadcast messages. This code duplicates functionality
already provided by the network stack's QoS option "network emulator".

tipc: Avoid reliable broadcast preparation for NACK messages

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

Enhance TIPC to skip unnecessary (and, in some cases, redundant)
preparation work when sending a broadcast link NACK message, since this
preparation is only required for broadcast messages that are sent in a
reliable manner. This change also fixes a bug that caused NACK messages
to be improperly counted as "TX packets" in TIPC's broadcast link
statistics.

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: Clean up tracking of node requesting a broadcast retransmit

2011-02-23T23:05:12+00:00

Allows the broadcast link to track the node that is requesting a retransmit
in a new field dedicated to that purpose. This replaces the existing
mechanism that (ab)uses an existing node structure linked list field to do
the tracking.

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.

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.

useful purpose.
