It was writing out IPBlock CIDRs like "192.168.0.5/4" rather than
"192.0.0.0/4".
Also, simplify a bit by basing the `cidr` and the `except` both on
podB, rather than one on podA and one on podB. (This is even
theoretically a bugfix, since it's not _required_ that podA and podB
be in the same /4.) Also reorganize the code to make the two test
cases more consistent with each other.
The test is super hacky and we'll not be needed once the corresponding
KEP is implemented, better to remove it that trying to fix it
perpetuating the hacky solution.
kube-proxy does not look at Endpoints ever, so it is incorrect for a
test to assume that there is any correlation between whether Endpoints
exist and whether a Service is working. Tests should only be using the
v1.Endpoints API if they are explicitly testing the behavior of
v1.Endpoints, the Endpoints controller, or the EndpointSlice mirroring
controller. There is no reason for any non SIG Network tests to be
testing any of those things, so there should be no references to
v1.Endpoints in test/e2e outside of test/e2e/network.
Also, simplify some pointlessly complicated e2eservice code.
The test was reusing the same variable for the service on each
iteration, the problem is that when the service creation fails, it
clears out the variable and in the next iteration it panics because is
trying to use a field on that same variable.
Not setting a total timeout for curl may result in hanging command if
the connection succeeded, but the data transfer did not.

* Add a test case to verify that specifying a port number
as the target port for restartable init containers in Service
* Add a failing test case to verify that specifying a named port
as the target port for restartable init containers in Service
As a quick fix for a flake, bceec5a3ff
introduced polling with wait.Poll in all callers of CheckDaemonStatus.
This commit reverts all callers to what they were before (CheckDaemonStatus +
ExpectNoError) and implements polling according to E2E best practices
(https://github.com/kubernetes/community/blob/master/contributors/devel/sig-testing/writing-good-e2e-tests.md#polling-and-timeouts):
- no logging while polling
- support for progress reporting while polling
- last but not least, produce an informative failure message in case of a
timeout, including a dump of the daemon set as YAML
The util for checking on daemonstatus was checking once if the Status of
the daemonset was reporting that all the desired Pods are scheduled and
ready.
However, the pattern used in the e2e test for this function was not
taking into consideration that the controller needs to propagate the Pod
status to the DeamonSet status, and was asserting on the condition only
once after waiting for all the Pods to be ready.
In order to avoid more churn code, change the CheckDaemonStatus
signature to the wait.Condition type and use it in a async poll loop on
the tests.
