2006-10-18[TIPC]: Unrecognized configuration command now returns error messageAllan Stephens
This patch causes TIPC to return an error message when it receives an unrecognized configuration command. (Previously, the sender received no feedback.)

2006-10-18[TIPC]: Added subscription cancellation capabilityLijun Chen
This patch allows a TIPC application to cancel an existing topology service subscription by re-requesting the subscription with the TIPC_SUB_CANCEL filter bit set. (All other bits of the cancel request must match the original subscription request.)

2006-10-18[TIPC]: Can now list multicast link on an isolated network nodeAllan Stephens
This patch fixes a minor bug that prevents "tipc-config -l" from displaying the multicast link if a TIPC node has never successfully established at least one unicast link.

2006-10-18[TIPC]: Fixed slow link reactivation when link tolerance is largeAllan Stephens
This patch corrects an issue wherein a previouly failed node could not reestablish a links to a non-failing node in the TIPC network until the latter node detected the link failure itself (which might be configured to take up to 30 seconds). The non-failing node now responds to link setup requests from a previously failed node in at most 1 second, allowing it to detect the link failure more quickly.

2006-10-18[TIPC]: Remove code bloat introduced by print buffer reworkAllan Stephens
This patch allows the compiler to optimize out any code that tries to send debugging output to the null print buffer (TIPC_NULL), a capability that was unintentionally broken during the recent print buffer rework.

2006-10-18[TIPC]: Added duplicate node address detection capabilityAllan Stephens
TIPC now rejects and logs link setup requests from node <Z.C.N> if the receiving node already has a functional link to that node on the associated interface, or if the requestor is using the same <Z.C.N> as the receiver.

2006-10-18[TIPC]: Stream socket can now send > 66000 bytes at a timeAllan Stephens

2006-10-18[TIPC]: Debug print buffer enhancements and fixesAllan Stephens
This change modifies TIPC's print buffer code as follows: 1) Now supports small print buffers (min. size reduced from 512 bytes to 64) 2) Now uses TIPC_NULL print buffer structure to indicate null device instead of NULL pointer (this simplified error handling) 3) Fixed misuse of console buffer structure by tipc_dump() 4) Added and corrected comments in various places Signed-off-by: Allan Stephens <allan.stephens@windriver.com> Signed-off-by: Per Liden <per.liden@ericsson.com> Signed-off-by: David S.

2006-10-04[TIPC]: fix printk warningJeff Garzik
gcc spits out this warning: net/tipc/link.c: In function ‘link_retransmit_failure’: net/tipc/link.c:1669: warning: cast from pointer to integer of different size More than a little bit ugly, storing integers in void*, but at least the code is correct, unlike some of the more crufty Linux kernel code found elsewhere. Rather than having two casts to massage the value into u32, it's easier just to have a single cast and use "%lu", since it's just a printk.

2006-07-03[TIPC] Fixed sk_buff panic caused by tipc_link_bundle_buf (REVISED)Allan Stephens
The recent change to direct inspection of bundle buffer tailroom did not account for the possiblity of unrequested tailroom added by skb_alloc(), thereby allowing a bundle to be created that exceeds the current link MTU. An additional check now ensures that bundling works correctly no matter if the bundle buffer is smaller, larger, or equal to the link MTU.

2006-06-29[TIPC]: Improve response to requests for node/link informationAllan Stephens
Now allocates reply space for "get links" request based on number of actual links, not number of potential links. Also, limits reply to "get links" and "get nodes" requests to 32KB to match capabilities of tipc-config utility that issued request.

2006-06-29[TIPC]: Fixed skb_under_panic caused by tipc_link_bundle_bufAllan Stephens
Now determines tailroom of bundle buffer by directly inspection of buffer. Previously, buffer was assumed to have a max capacity equal to the link MTU, but the addition of link MTU negotiation means that the link MTU can increase after the bundle buffer is allocated.
