Comment by Jozef Behran [ 04/Dec/14 ]

1. Download and install EXABGP: https://github.com/Exa-Networks/exabgp/releases
2. Configure a BGP peer at 127.0.0.1 in BGPCEP configuration.
3. Configure "example-bgp-rib" to have <local-as> set to 72.
4. You will have to run ODL as root (so it can attach to port 179) or use some other way to bridge port 179 to a port that can be bound by a non-root process. EXABGP is not able to communicate on a port other than 179.
5. Use the attached EXABGP configuration file (uncompress it first) to push 2000 routes from EXABGP to ODL.
6. Once EXABGP is finished pushing the routes, the bug will be triggered.

Attachment routes.cfg.xz has been added with description: EXABGP configuration with 2000 routes

Comment by Jozef Behran [ 04/Dec/14 ]

Here is a small Python utility that I use to bridge ports 179 and 1790. You can configure ODL to bind port 1790 and run it as a normal user. You then run this utility as root and it will bind port 179, wait for EXABGP there and once it shows up, it connects to ODL at 1790 and passes data back and forth. It also dumps the data on stdout as it passes them around.

Also, you need to make sure ODL is running at 127.0.0.2, otherwise the utility will not be able to find it. I think this is the default as I could not find anything in the BGPCEP configuration that would say something about which address ODL should listen on.

Comment by Moiz Raja [ 04/Dec/14 ]

Jozef,

Did you test BGP with Clustering turned off. That is have you tried with just in-memory data store. If so what was the maximum number of routes that you were able to push?

Comment by Jozef Behran [ 05/Dec/14 ]

Yes I did. In that case I needed to go up to about 5000 paths before seeing things to break down. Then I either got this exception or BGPCEP-174. It was not clear cut and I was not able to do much testing of this scenario as the script I used to test did not support the non-clustered scenario and I had to put considerable effort into implementing that.

Comment by Jozef Behran [ 09/Dec/14 ]

Latest results of testing are that this bug occurs nondeterministically. I got one occassion when 5000 paths got through but it happened only once. So now it is clear that each time a different number of routes will go through until one is caught up by this bug. The probability seems to be pretty high with 5000 routes (maybe 95% or even 99% and for 100000 routes it can be considered a sure thing.

It seems to be some sort of "thread synchronization problem" when either two threads are trying to delete the same node (because both realize at around the same time that the node exists) or one thread tries to use the node so it determines that it exists and then the other one deletes it.

Comment by Moiz Raja [ 09/Dec/14 ]

Based on the results seen with IMDS it looks to me like this is a BGP issue. The bug does manifest itself earlier with CDS because of the CDS's performance characteristics but this certainly seems to be an issue with the consumer.

Comment by Robert Varga [ 09/Dec/14 ]

Looking through the BGP code, it is most probably not at fault here. It uses transaction chaining, which means it has a single (per-table) thread of causality – thus precluding a conflict with self.

I suspect this is a problem in yangtools data tree merge/out/delete state squashing inside a transaction, but we will need more diagnostics to pin this down.

Comment by Robert Varga [ 09/Dec/14 ]

https://git.opendaylight.org/gerrit/13482 adds the diagnostic information needed to understand the nature of the transaction being committed.

Comment by Jozef Behran [ 09/Dec/14 ]

No longer problem with the latest image. On the latest image I used to meet this exception after the connection was abruptly closed by the other side however now I tend to not meet these as well. Closing bug as fixed.

This actually is a different bug. I filed it as BGPCEP-176. But yes, it is so confusingly similar to this one.

Note for readers: After asking for more information, Dana told me that the BGP session was closed due to Hold Timer Expired. The exception shown here happened some time after that.

Comment by Robert Varga [ 11/Dec/14 ]

Reopening as the core issue was not resolved.

Comment by Robert Varga [ 11/Dec/14 ]

Root cause analysis:

This bug has not been seen previously, even when we tried to load the code. Examination of BGP code indicates that it strictly adheres to TransactionChain API requirements and does not issue any deletes outside of it.

This means it was introduced by BUG-2255. Specifically it changed the way bulking is performed. Whereas without the BUG-2255 fix bulking was performed strictly on per-message basis, e.g. it was not possible to add and withdraw a prefix within the same transaction, the fix introduced transaction reuse.

With transaction reuse, we may perform a put() and a delete() for the same prefix – which is precisely what happens on peer disconnect. This triggers a WRITE/DELETE operation merge within the transaction.

As it turns out, this merge erases the WRITE record, but retains the DELETE record – which is correct in case the data has existed in the datastore, but turns into a DELETE of a non-existing node if this transaction was introducing it.

Comment by Robert Varga [ 11/Dec/14 ]

The bug has been tracked down to yang-data-impl's ModifiedNode.delete().
