RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

.`golang` now supports 4096 bit keys in x509 FIPS mode Previously, `golang` did not support the 4096 bit keys in x509 FIPS mode. Consequently, when the user used 4096 bit keys the program crashed. With this update, `golang` now supports 4096 bit keys in x509 FIPS mode.

Description Edjunior Barbosa Machado 2022-10-06 12:15:39 UTC 
Description of problem:
When GOLANG_FIPS=1 is defined, 'go get' from golang-1.19.1-2.module+el8.8.0+16778+5fbb74f5 fails with the following:

[root@hpe-apollo-cn99xx-14-vm-25 ~]# mkdir test; cd test
[root@hpe-apollo-cn99xx-14-vm-25 test]# go mod init test
go: creating new go.mod: module test
[root@hpe-apollo-cn99xx-14-vm-25 test]# GOLANG_FIPS=1 go get golang.org/x/net/html
go: module golang.org/x/net/html: Get "https://proxy.golang.org/golang.org/x/net/html/@v/list": x509: certificate specifies an incompatible key usage
[root@hpe-apollo-cn99xx-14-vm-25 test]# 

'go get' works as expected when not using GOLANG_FIPS=1:

[root@hpe-apollo-cn99xx-14-vm-25 test]# go get golang.org/x/net/html
go: downloading golang.org/x/net v0.0.0-20221004154528-8021a29435af
go: added golang.org/x/net v0.0.0-20221004154528-8021a29435af
[root@hpe-apollo-cn99xx-14-vm-25 test]# 

On s390x, the error message is slightly different, possibly also related to bug #1969844:

[root@s390x-kvm-061 test]# GOLANG_FIPS=1 go get -v golang.org/x/net/html
go: module golang.org/x/net/html: Get "https://proxy.golang.org/golang.org/x/net/html/@v/list": x509: certificate signed by unknown authority (possibly because of "crypto/rsa: verification error" while trying to verify candidate authority certificate "GTS CA 1C3")
[root@s390x-kvm-061 test]# go get -v golang.org/x/net/html
go: downloading golang.org/x/net v0.0.0-20221004154528-8021a29435af
go: added golang.org/x/net v0.0.0-20221004154528-8021a29435af
[root@s390x-kvm-061 test]# 

This issue is not reproducible with previous golang-1.18.4-1.module+el8.7.0+16015+724888d8 (go-toolset-rhel8-8070020220720230209.347cc21f).

I am told that this bug affects RHEL-8.6, too, and therefore OCP-4.12. Can this be backported?

I was unable to reproduce this with rhel-8.6 latest released golang-1.17.12-1.module+el8.6.0+16014+a372c00b (go-toolset-rhel8-8060020220720230014.97d7f71f) on RHEL-8.6.0-updates-20221019.0.
Could you please confirm which version of golang package is being used?
Comment 7 Motty Sisam 2022-10-24 12:28:33 UTC 
I was able to reproduce in OCP-4.12 (rhel-8.6) 

1. creating debug pod with admin privileges: 
$ oc debug deployment/cluster-cloud-controller-manager-operator --as-root -n openshift-cloud-controller-manager-operator

2. install gdb 
sh-4.4# yum install gdb -y

3. check go runtime version of the operator: 
sh-4.4# gdb /cluster-controller-manager-operator -ex "p 'runtime.buildVersion'" -ex q


output:
$1 = 0x1a65878 "go1.19.1"

I'm not familiar with ocp environment, but judging by this output, it is probably using a newer version of golang. RHEL-8.6 shipped go 1.17, whereas go 1.19 was just recently introduced with RHEL-8.8 builds.
