snowp · 2021-02-03T21:24:25Z

Is there any more information you can provide? A repro would be ideal, but config used for Envoy, config pushed via ECDS, envoy version, etc. would be helpful in debugging this

bianpengyuan · 2021-02-03T21:45:27Z

This is from a running istio cluster. I am not yet able to reproduce it. Trying to get a core dump if this happens again.

This issue has been automatically marked as stale because it has not had activity in the last 30 days. It will be closed in the next 7 days unless it is tagged "help wanted" or "no stalebot" or other activity occurs. Thank you for your contributions.

github-actions · 2021-03-21T08:03:40Z

This issue has been automatically closed because it has not had activity in the last 37 days. If this issue is still valid, please ping a maintainer and ask them to label it as "help wanted" or "no stalebot". Thank you for your contributions.

bianpengyuan · 2021-12-21T23:55:44Z

I can easily reproduce this now by deleting and recreating a filter which uses ECDS. I added some log instrument and find that crash is from this line at factory_context.messageValidationContext().dynamicValidationVisitor().

envoy/source/common/filter/config_discovery_impl.cc

Line 251 in 8c2da05

 factory_context.messageValidationContext().dynamicValidationVisitor(), factory); 

I enabled debug log and found there is a simultaneous listener update when ecds update happens. @lambdai has a theory that the crash is because factory context here is from the old listener.

cc @kyessenov

kyessenov · 2021-12-22T00:23:43Z

The factory context looks like server factory context, right? So it's the same across listeners.

bianpengyuan · 2021-12-22T03:20:55Z

The factory context looks like server factory context, right? So it's the same across listeners.

@kyessenov I am not sure.. you and @lambdai know this better than me : )

Could someone please reopen this issue? Maybe @snowp ?

kyessenov · 2021-12-22T18:37:33Z

Ok, feel free to assign to me or @lambdai.

Seems like the raw pointer from subscription to provider is used because of async cross thread post and deleted from main as owned by a listener. Will need to restructure using shared and weak pointers.

/reopen

rahulanand16nov · 2022-03-14T11:12:40Z

The problem is still producible with the 1.21.2-dev release.

kyessenov · 2022-03-14T16:21:58Z

@rahulanand16nov do you have a stack trace or reproducer?

rahulanand16nov · 2022-03-14T17:55:42Z

@kyessenov Sorry for the noise but for some reason it's working now even though it was reproducible when I recreated the whole cluster previously. Very weird.

Can you confirm this is on latest Envoy? The error is about removal of a filter from a non-main worker, which I think we handled.

we used envoy version is
version: edfec5636eb3494b1e5728891f8c0a6eba3e7d9f/1.20.3-dev/Clean/DEBUG/BoringSSL

and we cherry-pick this pr
#19630 build it self
can help to show which commit remove of a filter from a non-main worker?

kyessenov · 2022-07-08T18:16:26Z

I don't seem to have SHA edfec563.
I have trouble understanding how this happens. ECDS should delete Wasm filter config last on main thread due to runOnAllThreads. Is there any way to reproduce this issue?

fatedier · 2022-09-08T07:38:17Z

@kyessenov I use istio1.13.7 and envoy version: e0c6f64173cd0db9370e7ad8b1fbcee370a9f0f3/1.21.5/Clean/RELEASE/BoringSSL

Segmentation fault occured when I modify a wasm filter configruation.
