Description Franck Boudinet 2020-09-20 19:53:22 UTC
Description of problem:
Cannot login to an OCP 4.x OCP cluster (reproduced on 4.2.x & 4.3.x) with --insecure-skip-tls-verify=true from MacOS with keychain containing more than 250 certificates with trust policies

Version-Release number of selected component (if applicable):
oc Client Version 4.5.2 or above

How reproducible:

Steps to Reproduce:
1.Load around 250 certificates with Trust Policy in your MacOS keychain
2.oc login -u kubeadmin -p <mypwd> api.myocp.mydomain.local:6443 --insecure-skip-tls-verify=true

Actual results:
Login fails with error message: "error: net/http: TLS handshake timeout"

Expected results:
Login should succeed. As the user has explicitly asked for server certificates not to be checked by using the option: '--insecure-skip-tls-verify=true', the error above which is coming from an attempt to verify server certificate should not occur.

Comment 1 Maciej Szulik 2020-10-01 14:50:23 UTC
I’m adding UpcomingSprint, because I was occupied by fixing bugs with higher priority/severity, developing new features with higher priority, or developing new features to improve stability at a macro level. I will revisit this bug next sprint.

Comment 2 Michal Fojtik 2020-10-20 20:12:06 UTC
This bug hasn't had any activity in the last 30 days. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're marking this bug as "LifecycleStale" and decreasing the severity/priority. If you have further information on the current state of the bug, please update it, otherwise this bug can be closed in about 7 days. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. Additionally, you can add LifecycleFrozen into Keywords if you think this bug should never be marked as stale. Please consult with bug assignee before you do that.

Comment 3 Franck Boudinet 2020-11-07 13:26:43 UTC
Hi Guys, 

I saw it was parked for 4.7 so I stopped pushing for the fix. The alternative I'm using is to compile my own version of oc to benefit from the fix... 


Comment 4 Michal Fojtik 2020-11-07 14:12:13 UTC
The LifecycleStale keyword was removed because the bug got commented on recently.
The bug assignee was notified.

Comment 6 Franck Boudinet 2021-01-12 12:50:28 UTC
& happy new year, all the best for 2021 ! 

I see that you're re-opening this, are u willing/planning to get it integrated in 4.7 or am I getting it wrong ?
I had closed the related issue & PR as I had understood from previous comment in the PR.


Comment 7 Novonil Choudhuri 2021-01-12 15:06:28 UTC
Hello, Happy New year to you too. I am happy to have it fixed in 4.7 and backported to 4.6 as well. However i would like to know if there is any workaround available as of now.

Comment 10 Franck Boudinet 2021-01-13 08:32:56 UTC

Don't know if you looked at the analysis of the problem and in particular the inputs provided in the PR: https://github.com/openshift/oc/pull/514 on Sept 9, 2020. The reason of the problem is that even if the user selects the option "--insecure-skip-tls-verify=true" oc makes a first https request to the cluster and tries to validate the certificate (this validation should not happen, as per the request of the user adding the option insecure-skip-tls-verify=true and this is actually the reason for this bug report) which can be fixed with exactly one line of code.

The root cause of the bug is that on mac, certificates verification implemented in the go libraries can be very long and actually as written in the PR updates from Sep 9 (https://github.com/openshift/oc/pull/514#issuecomment-689348366): "...the duration of the checking is mostly coming from certificates with trust policies..."

- So one workaround can be to delete some (unused) certificates with trust policies in the keychain of the end user's mac so that the checking does not take so long, so the timeout does not occur and the connection can be made. 

Two other workarounds are also mentioned in the initial issue that lead to the PR mentioned above and to this bug report, see here: https://github.com/openshift/oc/issues/496
- do a 'sudo oc ...' from the mac, in this case the certificates verification only applies to a subset of the certificates in the keychain (the ones owned by root) and the timeout does not occur(post from July 22nd https://github.com/openshift/oc/issues/496#issuecomment-662164068)
- or add a cacert.pem file as parameter when invoking oc  (even a wrong one) to pass the "hurdle" of the first HEAD https request that fails  and then continue by selecting 'Use insecure connections? (y/n): y' (See here https://github.com/openshift/oc/issues/496#issuecomment-662177056)

Hope this helps.

Lowering the priority to reflect the customer case.

Thanks Frank. We tried the following but still it did not work. We will try the others and update here.

Comment 15 Franck Boudinet 2021-01-14 13:42:39 UTC

do you have the problem at a customer site, or are you trying to reproduce the problem on your test system ?
Have you tried:

GODEBUG=x509roots=1 oc login -u kubeadmin -p <myPassword>  api.<myCluster>.<myDomain>:6443

to make sure this is the same problem ?

Frank the problem is with customer site. I do not have a mac to test this.

Comment 18 Maciej Szulik 2021-01-18 12:45:42 UTC
Reading through https://github.com/golang/go/issues/18203#issuecomment-273005127 I found 
a suggestion to try CGO, we have another issue with mac + vpn (https://bugzilla.redhat.com/show_bug.cgi?id=1838512)
for which we have an open fix https://github.com/openshift/oc/pull/644.
Unfortunately, we can't merge that yet, see the PR comments. 

Can either of you verify if compiling oc with CGO_ENABLED=1 helps with this issue?

I don't see any difference. It still fails with the same error.

Comment 22 Franck Boudinet 2021-01-21 08:15:46 UTC
Hi Novonil,

did you try with export GODEBUG=x509roots=1 to really make sure that the problem you're facing is similar to the one I described in my issue ? You should see a list of certificate being one by one checkded and at some point the timeout occuring as they are too many.

Also may I ask which version of oc you're using ? I had put a lot of traces at the time when I investigated, I can have a look if I still have the VM where I did the cross compile to generate the oc mac version with these traces & provided it to you if that helps.


Comment 23 Novonil Choudhuri 2021-01-21 15:30:46 UTC

Yes tried this already and it is failing too.

We are using oc 4.6.9

Comment 25 Franck Boudinet 2021-01-22 17:46:40 UTC
OK Novonil,

based on what I read above, my conclusion is that :
  - either you did the test with the export of GODEBUG=x509roots=1 on linux, & I confirm no additional traces are displayed on linux with this option & I think there is no point to do that because the problem I reported was on mac only
  - or either the problem you are having is different from the one I reported

I just double checked with the oc client 4.6.9 on both linux & mac and:
  - on linux the option GODEBUG=x509roots=1 does not display any additional traces as mentionned above
  - but on mac it does, see below an example of the trace your customer should get:
GODEBUG=x509roots=1 oc login -u <username> -p <password> https://<myclusterapiurl>:6443 --loglevel=9

crypto/x509: trust settings for CN=sma-unleash.ratl.swg.usma.ibm.com,O=IBM: 4

btw I can also see that compared to the time where I raised the issue using 4.5.x, the oc client behavior has changed from that prospective, most probably some updates in the go librairies being used compared to oc 4.6.9 because here is the trace using oc client 4.5.2 & trying to connect to the same OCP server from exactly the same mac & user:
oc.4.5.2 login -u <username> -p <password> https://<myclusterapiurl>:6443 --loglevel=9

You can see that the output is different.
So please confirm that you're getting the 'crypto/x509:' kind of traces when running the oc login from a mac with the GODEBUG=x509roots=1 exports. If yes then hopefully it will help to confirm that the issue is due to the TLS certificates checking taking too long because of too many certificates and if not then it means the problem you're having is different from the one I raised

Have a good WE.

Comment 26 Maciej Szulik 2021-01-25 11:43:44 UTC
I spoke with other folks, we'll try to fix the bug in oc in 4.7

Comment 27 Maciej Szulik 2021-02-05 14:12:11 UTC
Due to other commitments we weren't able to get that resolved for 4.7, I'm pushing this over to 4.8

Comment 30 Maciej Szulik 2021-02-18 10:58:26 UTC
See the PR from the initial comment, I spoke with Standa and we've decided to go with that fix.

Comment 35 Mike Dame 2021-05-20 15:56:59 UTC
I still have not had a chance to check with the upstream auth folks about the proper way (if any) that we can allow both of these flags to be set.

See https://bugzilla.redhat.com/show_bug.cgi?id=1935102#c2 for more context on why this was reverted. It appears the limitation is not just oc (as previously thought in this bugzilla) but an internal k8s client restriction that will require more work.

I hit same issue in our customer environment. Do we have any suggestion for the workaround or solution yet?
While I couldn't use oc cli with this error, I could use curl (with token) to access APIs - all are in same jumpbox and same command window.

The cluster version is 4.10.12.
And I've tested different versions of oc cli, including 4.9.x and 4.10.x.

Detailed log to add for my comment #38: (I've redacted the real server name for customer security reason)

Comment 51 Arda Guclu 2022-08-01 06:05:21 UTC
I changed target release to 4.12 after talking with Zhou Ying

Comment 53 sakshi 2022-09-28 00:46:45 UTC
The customer mentioned that this issue is happening when they execute "oc login" command from openshift  RHEL client as well? I think we should test this on RHEL as well.

Comment 54 Arda Guclu 2022-09-28 08:30:49 UTC
I'd like to note that: The patch fixing the problem is operator system agnostic.
