tipc: cleanup function namespace

2010-10-16T18:13:24Z

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.

net: return operator cleanup

2010-09-23T21:33:39Z

Change "return (EXPR);" to "return EXPR;" return is not a function, parentheses are not required. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

tipc: Fix bug in broadcast link transmit statistics computation

2010-08-18T00:31:55Z

Modify TIPC's broadcast link so that it counts each piece of a fragmented message individually, rather than as treating the group as a single message. This ensures that proper correlation of sent and received traffic can be done when the broadcast link statistics are displayed, and is consistent with the way fragments are counted by TIPC's unicast links.

tipc: Fix premature broadcast advertisement by sending node

2010-08-18T00:31:55Z

Prevent a TIPC node from sending out a LINK_STATE message advertising a broadcast message that it is in the process of sending, but has not yet actually sent. Previously, it was possible for a link timeout to occur in between the time the broadcast link updated its "last message sent" counter and the time the broadcast message was passed to the broadcast bearer for transmission. This ensures that the code which issues the LINK_STATE message isn't informed of the new message until the broadcast bearer has had a chance to send it. Note: The "last message sent" value is stored in the "fsm_msg_count" field of the link structure used by the broadcast link. Since the broadcast link doesn't utilize the normal link FSM, this field can be re-used rather than adding a new field to the broadcast link.

tipc: Prevent crash when broadcast link cannot send to all nodes

2010-08-18T00:31:54Z

Allow TIPC's broadcast link to continue operation when it is unable to send a message to all nodes in the cluster. Previously, the broadcast link attempted to put the broadcast pseudo-bearer into a blocked state; however, this caused a crash because the associated bearer structure is only partially initialized. Further investigation has revealed some conceptual problems with blocking the pseudo-bearer; consequently, this functionality has been disabled for the time being and the undelivered message is eventually resent by the broadcast link's existing message retransmission mechanism (if possible).

tipc: Reduce footprint by un-inlining port list routines

2010-05-13T06:02:27Z

Converts port list inline routines that are more than one line into standard functions, thereby eliminating a significant amount of repeated code. Signed-off-by: Allan Stephens Signed-off-by: Paul Gortmaker Signed-off-by: David S. Miller

tipc: Reduce footprint by un-inlining nmap routines

2010-05-13T06:02:27Z

tipc: add tipc_ prefix to fcns targeted for un-inlining

2010-05-13T06:02:25Z

These functions have enough code in them such that they seem like sensible targets for un-inlining. Prior to doing that, this adds the tipc_ prefix to the functions, so that in the event of a panic dump or similar, the subsystem from which the functions come from is immediately clear.

tipc: Rename "multicast-link" to "broadcast-link"

2010-05-13T06:02:22Z

Make a cosmetic change to the name displayed for the broadcast link, to better reflect its true nature. Since TIPC utilizes this link to distribute name table information, in addition to multicast messages sent by user applications, the prior name "multicast-link" is no longer appropriate.

tipc: Increase frequency of load distribution over broadcast link

2010-03-17T04:23:23Z

Forward port commit 29eb572941501c40ac6e62dbc5043bf9ee76ee56 from git://tipc.cslab.ericsson.net/pub/git/people/allan/tipc.git Origional commit message: Increase frequency of load distribution over broadcast link This patch enhances the behavior of TIPC's broadcast link so that it alternates between redundant bearers (if available) after every message sent, rather than after every 10 messages. This change helps to speed up delivery of retransmitted messages by ensuring that they are not sent repeatedly over a bearer that is no longer working, but not yet recognized as failed. Tested by myself in the latest net-2.6 tree using the tipc sanity test suite Origionally-signed-off-by: Allan Stephens Signed-off-by: Neil Horman bcast.c | 35 ++++++++++++++--------------------- 1 file changed, 14 insertions(+), 21 deletions(-) Signed-off-by: David S.
