From 382100381c02ad0bcdb8f4776a6e49950cf0fa51 Mon Sep 17 00:00:00 2001 From: Sachin Ninganure Date: Sun, 31 May 2026 18:32:14 +0530 Subject: [PATCH 01/13] Add OTP test case 49216: API token logging security Validates that ovnkube-node container logs do not expose API tokens or Bearer authentication credentials. Test searches ovnkube-controller container logs for sensitive patterns (api-token, authorization, bearer) and filters false positives to ensure no actual tokens are logged.

category-based files and adds new test coverage: Changes: - Split networking_tools_test.go into 3 category-based files: * security_test.go - Security/compliance tests * networking_tools_test.go - Tools group tests only * multus_test.go - Multus CNI tests New Tests Added: 1. Medium-76652: Dummy CNI plugin support with Multus - Tests dummy interface creation with static IPAM - Validates network-status annotation contains dummy network - Confirms IP assignment (10.10.10.2/24) 2. Medium-77102: CIS file permissions for CNI configs - Checks multus config permissions (600 expected) - Validates whereabouts config permissions (600 expected) - Ensures CIS compliance for CNI configuration files - Uses exec into multus pods and debug pod on nodes Test Results (7 tests total): 5 blocking tests PASS (100% pass rate) 2 informing tests FAIL (expected - RBAC limitations) Test Organization: a) security_test.go: 49216, 77102 b) networking_tools_test.go: 55889, 67625, 67648 c) multus_test.go: 57589, 76652 --- openshift/test/otp/multus_test.go | 250 +++++++++++++++++

Mon Sep 17 00:00:00 2001 From: Sachin Ninganure Date: Thu, 4 Jun 2026 22:43:01 +0530 Subject: [PATCH 07/13] reorganized the OTP test suite into category-based files Changes: - Split networking_tools_test.go into 3 category-based files: security.go - Security/compliance tests networking_tools.go - Tools group tests only multus.go - Multus CNI tests - Removed otp_suite_test.go (not needed in OTE pattern) Added new tests: 1. Medium-76652: Dummy CNI plugin support with Multus - Tests dummy interface creation with static IPAM - Validates network-status annotation contains dummy network - Confirms IP assignment (10.10.10.2/24) 2. Medium-77102: CIS file permissions for CNI configs Code Review Fixes: - Fixed runOVNKubeTrace to return explicit error when no ovnkube-node pods found (previously returned nil error) - Removed unused srcIP/dstIP parameters from runOVNKubeTrace function - Updated all callers (67625, 67648 tests) Test Registration: - Added all 7 tests to openshift/test/tests.go (5 blocking, 2 informing) - Imported OTP package in main.go and e2e_test.go - Tests compile successfully but not appearing in OTE list (needs help) Test Results (verified with go test before OTE migration): - 5 blocking tests PASS (100% pass rate) - 2 informing tests FAIL (expected - RBAC limitations) Test Organization: - security.go: 49216, 77102 - networking_tools.go: 55889, 67625, 67648 - multus.go: 57589, 76652 --- openshift/.gitignore | 1 + openshift/cmd/ovn-kubernetes-tests-ext/main.go | 3 +++ openshift/test/e2e_test.go | 3 +++ openshift/test/otp/{multus_test.go => multus.go} | 0 ...networking_tools_test.go => networking_tools.go} | 0 openshift/test/otp/otp_suite_test.go | 13 ------------- .../test/otp/{security_test.go => security.go} | 0 openshift/test/tests.go | 12 +++++++++++- 8 files changed, 18 insertions(+), 14 deletions(-) rename openshift/test/otp/{multus_test.go => multus.go} (100%) rename openshift/test/otp/{networking_tools_test.go => networking_tools.go} (100%) delete mode 100644 openshift/test/otp/otp_suite_test.go rename openshift/test/otp/{security_test.go => security.go} (100%) diff --git a/openshift/.gitignore b/openshift/.gitignore index 968e914a11..10935954f1 100644 --- a/openshift/.gitignore +++ b/openshift/.gitignore @@ -1,2 +1,3 @@ vendor/ bin/ +ovn-kubernetes-tests-ext diff --git a/openshift/cmd/ovn-kubernetes-tests-ext/main.go b/openshift/cmd/ovn-kubernetes-tests-ext/main.go index 9f90ff0a20..f57c401bc9 100644 --- a/openshift/cmd/ovn-kubernetes-tests-ext/main.go +++ b/openshift/cmd/ovn-kubernetes-tests-ext/main.go @@ -14,6 +14,9 @@ import ( "github.com/ovn-kubernetes/ovn-kubernetes/test/e2e/deploymentconfig" "github.com/ovn-kubernetes/ovn-kubernetes/test/e2e/infraprovider" + // import OTP (OpenShift Tests Private) migration tests + _ "github.com/ovn-kubernetes/ovn-kubernetes/openshift/test/otp" + "github.com/openshift-eng/openshift-tests-extension/pkg/cmd" "github.com/openshift-eng/openshift-tests-extension/pkg/extension" "github.com/openshift-eng/openshift-tests-extension/pkg/extension/extensiontests" diff --git a/openshift/test/e2e_test.go b/openshift/test/e2e_test.go index 4ec7d744cc..4024b9af05 100644 --- a/openshift/test/e2e_test.go +++ b/openshift/test/e2e_test.go @@ -4,6 +4,9 @@ import ( // import OVN-Kubernetes E2Es _ "github.com/ovn-kubernetes/ovn-kubernetes/test/e2e" + // import OTP (OpenShift Tests Private) migration tests + _ "github.com/ovn-kubernetes/ovn-kubernetes/openshift/test/otp" + // Ensure that logging flags are part of the command line. _ "k8s.io/component-base/logs/testinit" ) diff --git a/openshift/test/otp/multus_test.go b/openshift/test/otp/multus.go similarity index 100% rename from openshift/test/otp/multus_test.go rename to openshift/test/otp/multus.go diff --git a/openshift/test/otp/networking_tools_test.go b/openshift/test/otp/networking_tools.go similarity index 100% rename from openshift/test/otp/networking_tools_test.go rename to openshift/test/otp/networking_tools.go diff --git a/openshift/test/otp/otp_suite_test.go b/openshift/test/otp/otp_suite_test.go deleted file mode 100644 index ba8a41c8a3..0000000000 --- a/openshift/test/otp/otp_suite_test.go +++ /dev/null @@ -1,13 +0,0 @@ -package otp - -import ( - "testing" - - .
