This commit defines the ClusterTrustBundlePEM projected volume types.
These types have been renamed from the KEP (PEMTrustAnchors) in order to
leave open the possibility of a similar projection drawing from a
yet-to-exist namespaced-scoped TrustBundle object, which came up during
KEP discussion.
* Add the projection field to internal and v1 APIs.
* Add validation to ensure that usages of the project must specify a
name and path.
* Add TODO covering admission control to forbid mirror pods from using
the projection.
Part of KEP-3257.

Kubernetes-commit: 878d037d3ba8fc4f11bf45a6cf5a66301ba89d82
KEP-2593 proposed to expand the existing node-ipam controller
to be configurable via a ClusterCIDR objects, however, there
were reasonable doubts on the SIG about the feature and after
several months of dicussions we decided to not move forward
with the KEP intree, hence, we are going to remove the existing
code, that is still in alpha.

* Add warning handler callback function in shortcut expander
Currently, errors in client-go are propagated back to the callers via
function returns. However, there is no elegant way for just warning users.
For example, when user wants to get a resource with it's short name format
and if there are multiple resources belonging to this short name, we need to
warn user about this ambugity which one is picked and which ones are discarded.
Not only to overcome this particular case mentioned above, but also propose a
way for the possible warnings in the future, this commit adds a warningHandler
callback function in shortcutExpander.
* Add warningPrinter functionality in ConfigFlags
ConfigFlags has neither warning user in a standardized
format functionality nor passing warning callback functions to other upper level
libraries such as client-go.
This commit adds an ability that user can set warningPrinters
according to their IOStreams and this warningPrinters will be used
to raise possible warnings happening not only in cli-runtime but
also in client-go.
* Pass warning callback function in ConfigFlags to shortcutExpander
This commit passes warning callback function to print possible
warnings happened in shortcut expander to warn user in a
standardized format.
* Add integration test for CRDs having ambiguous short names
This commit adds integration test to assure that warning message
related to this ambiguity is printed when resources are being retrieved via their short name
representations in cases where multiple resources have same
short names.
This integration test also ensures that the logic behind which resource
will be selected hasn't been changed which may cause disperancies in
clusters.
* Remove defaultConfigFlag global variable
* Move default config flags initialization into function
* Skip warning for versions of same group/resource
* Run update-vendor
* Warn only once when there are multiple versions registered for ambiguous resource
* Apply gocritic review
* Add multi-resource multi-version ambiguity unit test

checkWatchListConsistencyIfRequested performs a data consistency check only when
the KUBE_WATCHLIST_INCONSISTENCY_DETECTOR environment variable was set during a binary startup.
The consistency check is meant to be enforced only in the CI, not in production.
The check ensures that data retrieved by the watch-list api call
is exactly the same as data received by the standard list api call.
Note that this function will panic when data inconsistency is detected.
This is intentional because we want to catch it in the CI.

Because the EventBroadcaster code now has a a context, changing the EventSink
interface so that the methods accepts a context instead of using context.TODO
becomes possible.
Kubernetes-commit: 5dc540ff57eed5d0e6bc8476f95fe03b7a983cf5
Using StartRecordingToSinkWithContext instead of StartRecordingToSink and
StartLogging instead of StartStructuredLogging has several advantages:
- Spawned goroutines no longer get stuck for extended periods of
time during shutdown when passing in a context that gets canceled.
- Log output can be directed towards a specific logger instead of the global
default, for example one which writes to a testing.T instance.
- The new methods return an error when something went wrong instead of
merely recording the error.
That last point is the reason for deprecating the old methods instead of merely
adding new alternatives.
Setting a context when constructing an EventBroadcaster makes calling Shutdown
optional. It can also be used to specify the logger.
Both EventRecorder interfaces in tools/events and tools/record now have a
WithLogger helper. Using that method is optional, but recommended to support
contextual logging properly. Without it, errors that occur while emitting an
event are not associated with the caller.

The "set" list type was chosen because it seemed appropriate (no duplicates!)
but that made tracking of managed fields more expensive (each entry in the list
is tracked, not the entire field) and for no good reason (one client is
responsible for the entire list).
Therefore the type gets changed to "atomic". Server-side-apply has not been
used in the past and PodSchedulingContext objects are short-lived and still in
alpha, so the any potential compatibility issues should be minor.
The scheduling throughput in scheduler_perf increases:
name old SchedulingThroughput/Average new SchedulingThroughput/Average

Client-side extract calls depend on `managedFields`, which might not be

They are okay in test files (because the API has to be tested), in the

provided) and in unstructured.go (same reason).

Currently, openapiv3 discovery uses requestURI to discover resources.
However, that does not work when the rest endpoint contains prefixes
(e.g. `http://localhost/test-endpoint/`).
Because requestURI overwrites prefixes also in rest endpoint
(e.g. `http://localhost/openapiv3/apis/apps/v1`).
Since `absPath` keeps the prefixes in the rest endpoint,
this PR changes to absPath instead requestURI.

A few notes about the change:
1. I need to initialize the fileclient once, in an init function, so I
don't have access to `testing.T` yet.
2. I want to be able to configure the openapi files that I use
3. We already have a "cache" client that wraps another client, we don't
need to re-implement caching here, one can just do:
`cache.NewClient(openapitest.NewFileClient("some/path"))` to do a cached
client. Or initialize it in an init/global var.
Since there is still some value to use the embedded file, make an
alternative constructor while using fs.FS interface to be able to
manipulate both virtual and disk-based filesystems.

This is useful to both reduce the code complexity, and to ensure clients
get the "newest" version of an object known when its deleted. This is
all best-effort, but for clients it makes more sense giving them the
newest object they observed rather than an old one.
This is especially useful when an object is recreated. eg.
Object A with key K is in the KnownObjects store;
- DELETE delta for A is queued with key K
- CREATE delta for B is queued with key K
- Replace without any object with key K in it.
In this situation its better to create a DELETE delta with
DeletedFinalStateUnknown with B (with this patch), than it is to give
the client an DeletedFinalStateUnknown with A (without this patch).

This fixes a race condition when a "short lived" object
is created and the create event is still present on the queue
when a relist replaces the state. Previously that would lead in the
object being leaked.
The way this could happen is roughly;
1. new Object is added O, agent gets CREATED event for it
2. watch is terminated, and the agent runs a new list, L
3. CREATE event for O is still on the queue to be processed.
4. informer replaces the old data in store with L, and O is not in L
- Since O is not in the store, and not in the list L, no DELETED event
is queued
5. CREATE event for O is still on the queue to be processed.
6. CREATE event for O is processed
7. O is <leaked>; its present in the cache but not in k8s.
With this patch, on step 4. above it would create a DELETED event
ensuring that the object will be removed.

12 times with a delay of ~10s between each retry. In apiserver integration
tests that caused the goroutine to linger long after the corresponding
apiserver of the test was shut down.

The kube-apiserver validation expects the Count of an EventSeries to be
at least 2, otherwise it rejects the Event. There was is discrepancy
between the client and the server since the client was iniatizing an
EventSeries to a count of 1.
According to the original KEP, the first event emitted should have an
EventSeries set to nil and the second isomorphic event should have an
EventSeries with a count of 2. Thus, we should matcht the behavior
define by the KEP and update the client.
Also, as an effort to make the old clients compatible with the servers,
we should allow Events with an EventSeries count of 1 to prevent any
unexpected rejections.

This fixes the following warning (error?) in the apiserver:
E0126 18:10:38.665239 16370 fieldmanager.go:210] "[SHOULD NOT HAPPEN] failed to update managedFields" err="failed to convert new object (test/claim-84; resource.k8s.io/v1alpha1, Kind=ResourceClaim) to smd typed: .status.reservedFor: element 0: associative list without keys has an element that's a map type" VersionKind="/, Kind=" namespace="test" name="claim-84"
The root cause is the same as in e50e8a0c919c0e02dc9a0ffaebb685d5348027b4:
nothing in Kubernetes outright complains about a list of items where the item
type is comparable in Go, but not a simple type. This nonetheless isn't
supposed to be done in the API and can causes problems elsewhere.
For the ReservedFor field, everything seems to work okay except for the
warning. However, it's better to follow conventions and use a map. This is
possible in this case because UID is guaranteed to be a unique key.
Validation is now stricter than before, which is a good thing: previously,
two entries with the same UID were allowed as long as some other field was
different, which wasn't a situation that should have been allowed.

While refactoring the backoff manager to simplify and unify the code
in wait a race condition was encountered in
TestSharedInformerWatchDisruption. The new implementation failed
because the fake clock was not propagated to the backoff managers
when the reflector was used in a controller. After ensuring the
mangaers, reflector, controller, and informer shared the same
clock the test needed was updated to avoid the race condition by
advancing the fake clock and adding real sleeps to wait for
asynchronous propagation of the various goroutines in the controller.
Due to the deep structure of informers it is difficult to inject
hooks to avoid having to perform sleeps. At a minimum the FakeClock
interface should allow a caller to determine the number of waiting
timers (to avoid the first sleep).

Currently, when the remote connection is unexpected closed, forward() prints an error message saying "lost connection to pod" via runtime.HandleError, but then it returns nil for the error.
This prevents the caller from being able to handle this error differently.
This commit changes forward() to return the "lost connection to pod" error so that it can be handled by the caller.
Making this change enables kubectl port-forward to exit with code 1, instead of 0, which is the expected behavior for a command that has failed.

When attempting to record a new Event and a new Serie on the apiserver
at the same time, the patch of the Serie might happen before the Event
is actually created. In that case, we handle the error and try to create
the Event. But the Event might be created during that period of time and
it is treated as an error today. So in order to handle that scenario, we
need to retry when a Create call for a Serie results in an AlreadyExist
error.

Kubernetes-commit: 2f83117bcfe30ad3ada7f1ca66f4b885a1d5df25
There was a data race in the recordToSink function that caused changes
to the events cache to be overriden if events were emitted
simultaneously via Eventf calls.
The race lies in the fact that when recording an Event, there might be
multiple calls updating the cache simultaneously. The lock period is
optimized so that after updating the cache with the new Event, the lock
is unlocked until the Event is recorded on the apiserver side and then
the cache is locked again to be updated with the new value returned by
the apiserver.
The are a few problem with the approach:
1. If two identical Events are emitted successively the changes of the
second Event will override the first one. In code the following
happen:
1. Eventf(ev1)
2. Eventf(ev2)
3. Lock cache
4. Set cache[getKey(ev1)] = &ev1
5. Unlock cache
6. Lock cache
7. Update cache[getKey(ev2)] = &ev1 + Series{Count: 1}
8. Unlock cache
9. Start attempting to record the first event &ev1 on the apiserver side.
This can be mitigated by recording a copy of the Event stored in
cache instead of reusing the pointer from the cache.
2. When the Event has been recorded on the apiserver the cache is
updated again with the value of the Event returned by the server.
This update will override any changes made to the cache entry when
attempting to record the new Event since the cache was unlocked at
that time. This might lead to some inconsistencies when dealing with
EventSeries since the count may be overriden or the client might even
try to record the first isomorphic Event multiple time.
This could be mitigated with a lock that has a larger scope, but we
shouldn't want to reflect Event returned by the apiserver in the
cache in the first place since mutation could mess with the
aggregation by either allowing users to manipulate values to update
a different cache entry or even having two cache entries for the same
Events.

Part of the API discovery cache uses an HTTP RoundTripper that
transparently caches responses to disk. The upstream implementation of
the disk cache is hard coded to call Sync() on every file it writes.
This has noticably poor performance on modern Macs, which ask their disk
controllers to flush all the way to persistant storage because Go uses
the `F_FULLFSYNC` fnctl. Apple recommends minimizing this behaviour in
order to avoid degrading performance and increasing disk wear.
The content of the discovery cache is not critical; it is indeed just a
cache and can be recreated by hitting the API servers' discovery
endpoints. This commit replaces upstream httpcache's diskcache
implementation with a similar implementation that can use CRC-32
checksums to detect corrupted cache entries at read-time. When such an
entry is detected (e.g. because it was only partially flushed to
permanent storage before the host lost power) the cache will report a
miss. This causes httpcache to fall back to its underlying HTTP
transport (i.e. the real API server) and re-cache the resulting value.
Apart from adding CRC-32 checksums and avoiding calling fsync this
implementation differs from upstream httpcache's diskcache package in
that it uses FNV-32a hashes rather than MD5 hashes of cache keys in
order to generate filenames.

To be able to implement controllers that are dynamically deciding
on which resources to watch, it is required to get rid of
dedicated watches and event handlers again. This requires the
possibility to remove event handlers from SharedIndexInformers again.
Stopping an informer is not sufficient, because there might
be multiple controllers in a controller manager that independently
decide which resources to watch.
Unfortunately the ResourceEventHandler interface encourages to use
value objects for handlers (like the ResourceEventHandlerFuncs
struct, that uses value receivers to implement the interface).
Go does not support comparison of function pointers and therefore
the comparison of such structs is not possible, also. To be able
to remove all kinds of handlers and to solve the problem of
multi-registrations of handlers a registration handle is introduced.
It is returned when adding a handler and can later be used to remove
the registration again. This handle directly stores the created
listener to simplify the deletion.

This commit refactors the retry logic to include resetting the
request body. The reset logic will be called iff it is not the
first attempt. This refactor is nescessary mainly because now
as per the retry logic, we always ensure that the request body
is reset *after* the response body is *fully* read and closed
in order to reuse the same TCP connection.
Previously, the reset of the request body and the call to read
and close the response body were not in the right order, which
leads to race conditions.
This commit also adds a test that verifies the order in which
the function calls are made to ensure that we seek only after
the response body is closed.

Some of these changes are cosmetic (repeatedly calling klog.V instead of

- Logging a message only above a certain verbosity threshold without
recording that verbosity level (if klog.V().Enabled() { klog.Info... }):
this matters when using a logging backend which records the verbosity
level.
- Passing a format string with parameters to a logging function that
doesn't do string formatting.
All of these locations where found by the enhanced logcheck tool from

* De-share the Handler struct in core API
An upcoming PR adds a handler that only applies on one of these paths.
Having fields that don't work seems bad.
This never should have been shared. Lifecycle hooks are like a "write"
while probes are more like a "read". HTTPGet and TCPSocket don't really
make sense as lifecycle hooks (but I can't take that back). When we add
gRPC, it is EXPLICITLY a health check (defined by gRPC) not an arbitrary
RPC - so a probe makes sense but a hook does not.
In the future I can also see adding lifecycle hooks that don't make
sense as probes. E.g. 'sleep' is a common lifecycle request. The only
option is `exec`, which requires having a sleep binary in your image.

See https://github.com/grpc/grpc-go/issues/4758 for a real world example
of this leaking 2gb+ of data.
Basically, when we do `q.queue[1:]` we are just repositioning the slice.
The underlying array is still active, which contains the object formerly
known as `q.queue[0]`. Because its referencing this object, it will not
be GCed. The only thing that will trigger it to free is eventually when
we add enough to the queue that we allocate a whole new array.
Instead, we should explicitly clear out the old space when we remove it
from the queue. This ensures the object can be GCed, assuming the users'
application doesn't reference it anymore.

This replaces the experimental logr v0.4 with the stable v1.1.0
release. This is a breaking API change for some users because:
- Comparing logr.Logger against nil is not possible anymore:
it's now a struct instead of an interface. Code which
allows a nil logger should switch to *logr.Logger as type.
- Logger implementations must be updated in lockstep.
Instead of updating the forked zapr code in json.go, directly using
the original go-logr/zapr is simpler and avoids duplication of effort.
The updated zapr supports logging of numeric verbosity. Error messages
don't have a verbosity (= always get logged), so "v" is not getting
added to them anymore.
Source code logging for panic messages got fixed so that it references
the code with the invalid log call, not the json.go implementation.
Finally, zapr includes additional information in its panic
messages ("zap field", "ignored key", "invalid key").

If the informers handlers are slow processing the objects, the deltaFIFO
blocks the queue and the streamWatchers can not add new elements to the
queue, creating contention and causing different problems, like high
memory usage.
The problem is not easy to identify from a user perspective, typically
you can use pprof to identify a high memory usage on the StreamWatchers
or some handler consuming most of the cpu time, but users should not
have to profile the golang binary in order to know that.
Metrics were disabled on the reflector because of memory leaks, also
monitoring the queue depth can't give a good signal, since it never goes high
However, we can trace slow handlers and inform users about the problem.

This change updates the CSR API to add a new, optional field called
expirationSeconds. This field is a request to the signer for the
maximum duration the client wishes the cert to have. The signer is
free to ignore this request based on its own internal policy. The
signers built-in to KCM will honor this field if it is not set to a
value greater than --cluster-signing-duration. The minimum allowed
value for this field is 600 seconds (ten minutes).
This change will help enforce safer durations for certificates in
the Kube ecosystem and will help related projects such as
cert-manager with their migration to the Kube CSR API.
Future enhancements may update the Kubelet to take advantage of this
field when it is configured in a way that can tolerate shorter
certificate lifespans with regular rotation.

- typed fixtures are converted to unstructured types
- automatically register fixture gvks with the scheme
This should make the dynamic client 'flexible' with it's inputs like it was

Kubelet cert rotation involves two certificate manager instances
(one for client and one for server certs) and the log lines are
identical and confusing. Since certificate manager is a utility
library it is also inappropriate to simply assume klog output is
sufficient.
certificate.Manager now accepts a Name and Logf function on its
config struct to identify the purpose of the manager and to
provide a way to redirect where output should go. If Name is
absent, the name is defaulted from the SignerName, and if that
is not found then the name is set to "client auth" if that is
a provided key usage, or "certificate" otherwise. If Logf is
not provided it defaults to klog.V(2). as today. The name is printed
in "foo: bar" form on every line, but can be converted to structured
logging in the future. The log level is not customizable and it
is up to the caller to decide whether that is an issue.
Some log messages are slightly cleaned up to more clearly indicate
their intent. One log message is removed in a utility function that
was already at v(4) and less likely to be needed.
The default behavior of the certificate manager is as before and
the kubelet now identifies the server and client signerName as
separate entities:

This changes the `/ephemeralcontainers` subresource of `/pods` to use
the `Pod` kind rather than `EphemeralContainers`.
When designing this API initially it seemed preferable to create a new
kind containing only the pod's ephemeral containers, similar to how
binding and scaling work.
It later became clear that this made admission control more difficult
because the controller wouldn't be presented with the entire Pod, so we
updated this to operate on the entire Pod, similar to how `/status`
works.

We are not sure why this was stdout, since stdin is what the user uses to pass
information to the exec plugin.
There is a question of backwards compatibility here. Our take is that this is a
bug, and so we are ameliorating behavior instead of breaking behavior. There are
2 main cases to consider with respect to backwards compatibility:
1. an existing exec plugin depended on stdin being hooked up to them if stdout
was a terminal (e.g., echo foo | client-go-command-line-tool); we believe
this is an anti-pattern, since the client-go-command-line-tool could be using
stdin elsewhere (e.g., echo foo | kubectl apply -f -)
2. an existing exec plugin depended on stdin not being hooked up to them if
stdout was not a terminal (e.g., client-go-command-line-tool >/dev/null);
hopefully there are very few plugins that have tried to base logic off of
whether stdin returned EOF immediately, since this could also happen when
something else is wrong with stdin
We hope to apply a stronger fix to this exec plugin user interaction stuff in a
future release.

`debuggingRoundTripper` is a useful throbleshooting tool to debug of Kubernetes API requests and their timing.
Unfortunately, as of today, it can only be used via the `DebugWrappers` function, which automatically adjust the amount of debug information exposed by the roundTripper based on the configured `klog` verbosity.
While `DebugWrappers` definitely fits the purpose for clients using `klog`, this is currently hard to be used for controllers using `controller-runtime`, which uses `github.com/go-logr/logr` for logging.
In this PR we change the visibility of `newDebuggingRoundTripper` and `debugLevel` in order to be directly accessible from users of the `k8s.io/client-go/transport` package.
In particular, the changes proposed in this PR allow users of `controller-runtime` to use the `debuggingRoundTripper` to intercept Kubernetes API requests as follows
```go
import (
ctrl "sigs.k8s.io/controller-runtime"
)
func init() {
ctrl.SetLogger(zap.New())
}
func main() {
// wrap the http transport used by the Kubernetes client
restConfig, err := ctrl.GetConfig()
checkError(setupLog, err, "unable to get kubernetes client config")
restConfig.Wrap(func(rt http.RoundTripper) http.RoundTripper {
return transport.NewDebuggingRoundTripper(rt, transport.DebugJustURL)
})
...
}
```

This changes the event recorder to use the equivalent of a select
statement instead of a goroutine to record events.
Previously, we used a goroutine to make event recording non-blocking.
Unfortunately, this writes to a channel, and during shutdown we then
race to write to a closed channel, panicing (caught by the error
handler, but still) and making the race detector unhappy.
Instead, we now use the select statement to make event emitting
non-blocking, and if we'd block, we just drop the event. We already
drop events if a particular sink is overloaded, so this just moves the
incoming event queue to match that behavior (and makes the incoming
event queue much longer).
This means that, if the user uses `Eventf` and friends correctly (i.e.
ensure they've returned by the time we call `Shutdown`), it's
now safe to call Shutdown. This matches the conventional go guidance on
channels: the writer should call close.

github.com/hashicorp/golang-lru is MPL 2 licensed, which means that
anyone who distributes code or binaries that incorporates it needs to
include its source code, even if they haven't made any modifications.
Since lrucacheexpire is picked up as a dependency of using the shared
informers in client-go, that's potentially a lot of distributors.
Most other deps of client-go are Apache 2.0, MIT, or BSD-like
licensed, which only requires including the license.
Rather than reverting to groupcache/lru, I just reimplemented the
functionality we need, which isn't much.

- Avoid breaking existing manual declarations of rest.Config instances by

- Use client.authentication.k8s.io/exec to qualify exec cluster extension.

Currently when ListAndWatch() receives a connection refused error, it is
assumed to be due to the apiserver being transiently unresponsive. In
situations where a controller is running outside the k8s cluster it's
controlling, it is more common for the controller to lose connection
permanently to the apiserver and needs to exponentially backoff its
retry rather than continously spamming logs with Watch attempts that
will never succeed.

Hello gophers,
Version v0.3.3 of golang.org/x/text fixes a vulnerability in the golang.org/x/text/encoding/unicode package which could lead to the UTF-16 decoder entering an infinite loop, causing the program to crash or run out of memory.
An attacker could provide a single byte to a UTF16 decoder instantiated with UseBOM or ExpectBOM to trigger an infinite loop if the String function on the Decoder is called, or the Decoder is passed to golang.org/x/text/transform.String.
transform.String has also been hardened not to enter an infinite loop if a Transformer keeps returning ErrShortSrc even if atEOF is true.
This issue was first filed as Issue 39491 by GitHub user abacabadabacaba and reported to the security team by Anton Gyllenberg. It is tracked as CVE-2020-14040.
Cheers,
Katie for the Go team

If a bearer token is present in a request, the exec credential plugin should accept that as the chosen method of authentication. Judging by an [earlier comment in exec.go](c18bc7e9f7/staging/src/k8s.io/client-go/plugin/pkg/client/auth/exec/exec.go (L217)), this was already intended. This would however not work since UpdateTransportConfig would set the GetCert callback which would then get called by the transport, triggering the exec plugin action even with a token present in the request. See linked issue for further details.

This commit adds the ability for users to specify an install hint for
their exec credential provider binary.
In the exec credential provider workflow, if the exec credential binary
does not exist, then the user will see some sort of ugly
exec: exec: "does-not-exist": executable file not found in $PATH
error message. If some user downloads a kubeconfig from somewhere, they
may not know that kubectl is trying to use a binary to obtain
credentials to auth to the API, and scratch their head when they see
this error message. Furthermore, even if a user does know that their
kubeconfig is trying to run a binary, they might not know how to obtain
the binary. This install hint seeks to ease the above 2 user pains.

The fake clientset used a slice to store each kind of objects, it's
quite slow to init the clientset with massive objects because it checked
existence of an object by traversing all objects before adding it, which
leads to O(n^2) time complexity. Also, the Create, Update, Get, Delete
methods needs to traverse all objects, which affects the time statistic
of code that calls them.
This patch changed to use a map to store each kind of objects, reduced
the time complexity of initializing clientset to O(n) and the Create,
Update, Get, Delete to O(1).
For example:
Before this patch, it took ~29s to init a clientset with 30000 Pods,
and 2~4ms to create and get an Pod.
After this patch, it took ~50ms to init a clientset with 30000 Pods,
and tens of µs to create and get an Pod.

The `recorder.PastEventf` method wasn't actually working as advertised.
It was supposed to accept a timestamp, which would be used when
generating the event. However, as the
[source code](https://github.com/kubernetes/kubernetes/blob/master/staging/src/k8s.io/client-go/tools/record/event.go#L316)
shows, this `timestamp` was never actually used.
In other words, `PastEventf` is identical to `Eventf`.
We have two options: one would be to fix `PastEventf` so that it works
as advertised. The other would be to delete `PastEventf` and only
support `Eventf`.
Ultimately, I could only find one use of `PastEventf` in the code base,
so I propose we just delete `PastEventf` and convert all uses to
`Eventf`.

In other parts of the system (notably in RBAC rules), the "resource/subresource" notation is common to specify an explicit subresource. This makes this notation available to tests that use the `Matches` function on client actions as well.

Background:
Before this change, DeltaFIFO emits the Sync DeltaType on Resync() and
Replace(). Seperately, the SharedInformer will only pass that event
on to handlers that have a ResyncInterval and are due for Resync. This
can cause updates to be lost if an object changes as part of the Replace(),
as it may be incorrectly discarded if the handler does not want a Resync.
What this change does:
Creates a new DeltaType, Replaced, which is emitted by DeltaFIFO on
Replace(). For backwards compatability concerns, the old behavior of
always emitting Sync is preserved unless explicity overridden.
As a result, if an object changes (or is added) on Replace(), now all
SharedInformer handlers will get a correct Add() or Update()
notification.
One additional side-effect is that handlers which do not ever want
Resyncs will now see them for all objects that have not changed during
the Replace.

This patch removes pkg/util/mount completely, and replaces it with the
mount package now located at k8s.io/utils/mount. The code found at
k8s.io/utils/mount was moved there from pkg/util/mount, so the code is
identical, just no longer in-tree to k/k.

- Delete backing string set from a threadSafeMap index when the string set length reaches 0.
Kubernetes-commit: 41be6d65d88728f443966da83b62d545684576ab
This commit performs two refactors and fixes a bug.
Refactor 1 changes the signature of Request to take a RESTClient, which
removes the extra copy of everything on RESTClient from Request. A pair
of optional constructors are added for testing. The major functional
change is that Request no longer has the shim HTTPClient interface and
so some test cases change slightly because we are now going through
http.Client code paths instead of direct to our test stubs.
Refactor 2 changes the signature of RESTClient to take a
ClientContentConfig instead of ContentConfig - the primary difference
being that ClientContentConfig uses ClientNegotiator instead of
NegotiatedSerializer and the old Serializers type. We also collapse
some redundancies (like the rate limiter can be created outside the
constructor).
The bug fix is to negotiate the streaming content type on a Watch()
like we do for requests. We stop caching the decoder and simply
resolve it on the request. We also clean up the dynamic client
and remove the extra WatchSpecificVersions() method by providing
a properly wrapped dynamic client.
Kubernetes-commit: 3b780c64b89606f4e6b21f48fb9c305d5998b9e5
- Added thread_safe_store_test exercising new index backing string set delete at 0 functionality.

Close outbound connections when using a cert callback and certificates rotate. This means that we won't get into a situation where we have open TLS connections using expires certs, which would get unauthorized errors at the apiserver
Attempt to retrieve a new certificate if open connections near expiry, to prevent the case where the cert expires but we haven't yet opened a new TLS connection and so GetClientCertificate hasn't been called.
Move certificate rotation logic to a separate function
Rely on generic transport approach to handle closing TLS client connections in exec plugin; no need to use a custom dialer as this is now the default behaviour of the transport when faced with a cert callback. As a result of handling this case, it is now safe to apply the transport approach even in cases where there is a custom Dialer (this will not affect kubelet connrotation behaviour, because that uses a custom transport, not just a dialer).
Check expiry of the full TLS certificate chain that will be presented, not only the leaf. Only do this check when the certificate actually rotates. Start the certificate as a zero value, not nil, so that we don't see a rotation when there is in fact no client certificate
Drain the timer when we first initialize it, to prevent immediate rotation. Additionally, calling Stop() on the timer isn't necessary.
Don't close connections on the first 'rotation'
Remove RotateCertFromDisk and RotateClientCertFromDisk flags.
Instead simply default to rotating certificates from disk whenever files are exclusively provided.
Add integration test for client certificate rotation
Simplify logic; rotate every 5 mins
Instead of trying to be clever and checking for rotation just before an
expiry, let's match the logic of the new apiserver cert rotation logic
as much as possible. We write a controller that checks for rotation
every 5 mins. We also check on every new connection.
Respond to review
Fix kubelet certificate rotation logic
The kubelet rotation logic seems to be broken because it expects its
cert files to end up as cert data whereas in fact they end up as a
callback. We should just call the tlsConfig GetCertificate callback
as this obtains a current cert even in cases where a static cert is
provided, and check that for validity.
Later on we can refactor all of the kubelet logic so that all it does is
write files to disk, and the cert rotation work does the rest.
Only read certificates once a second at most
Respond to review
1) Don't blat the cert file names
2) Make it more obvious where we have a neverstop
3) Naming
4) Verbosity
Avoid cache busting
Use filenames as cache keys when rotation is enabled, and add the
rotation later in the creation of the transport.
Caller should start the rotating dialer
Add continuous request rotation test
Rebase: use context in List/Watch
Swap goroutine around
Retry GETs on net.IsProbableEOF
Refactor certRotatingDialer
For simplicity, don't affect cert callbacks
To reduce change surface, lets not try to handle the case of a changing
GetCert callback in this PR. Reverting this commit should be sufficient
to handle that case in a later PR.
This PR will focus only on rotating certificate and key files.
Therefore, we don't need to modify the exec auth plugin.

becomes inconvenient dealing with multiple clusters on different

It was previously possible to instantiate `Reflector` with
`*unstructured.Unstructured` as the expected type but this did not
support checking that event objects were of the correct API
type (e.g. if event object was `v1.Pod` in `Unstructured` form but
`v1.Service` was expected). This commit adds support for providing a
GVK via an `Unstructured` expected type to compare with the GVK of
event objects. The GVK will also be used in reflector log output.

`Get` method within the fake clientset returns an object that would not be normally returned when using the real clientset. Reproducer:
```go
package main
import (
v1 "k8s.io/api/core/v1"
metav1 "k8s.io/apimachinery/pkg/apis/meta/v1"
"k8s.io/client-go/kubernetes/fake"
)
func main () {
cm := &v1.ConfigMap{
ObjectMeta: metav1.ObjectMeta{Namespace: metav1.NamespaceSystem, Name: "cm"},
}
client := fake.NewSimpleClientset(cm)
obj, err := client.CoreV1().ConfigMaps("").Get("", metav1.GetOptions{})
if err != nil {
panic(err)
}
fmt.Printf("obj: %#v\n", obj)
}
```
stored under `test.go` of `github.com/kubernetes/kubernetes` (master HEAD) root directory and ran:
```sh
$ go run test.go
obj: &v1.ConfigMap{TypeMeta:v1.TypeMeta{Kind:"", APIVersion:""}, ObjectMeta:v1.ObjectMeta{Name:"cm", GenerateName:"", Namespace:"kube-system", SelfLink:"", UID:"", ResourceVersion:"", Generation:0, CreationTimestamp:v1.Time{Time:time.Time{wall:0x0, ext:0, loc:(*time.Location)(nil)}}, DeletionTimestamp:(*v1.Time)(nil), DeletionGracePeriodSeconds:(*int64)(nil), Labels:map[string]string(nil), Annotations:map[string]string(nil), OwnerReferences:[]v1.OwnerReference(nil), Finalizers:[]string(nil), ClusterName:"", ManagedFields:[]v1.ManagedFieldsEntry(nil)}, Data:map[string]string(nil), BinaryData:map[string][]uint8(nil)}
```
As you can see fake clientset with a "test" configmap is created. When getting the object through the clientset back, I intentionally set the object name to an empty string. I would expect to get an error saying config map "" was not found. However, I get "test" configmap instead.
Reason for that is inside implementation of `filterByNamespaceAndName` private function:
```go
func filterByNamespaceAndName(objs []runtime.Object, ns, name string) ([]runtime.Object, error) {
var res []runtime.Object
for _, obj := range objs {
acc, err := meta.Accessor(obj)
if err != nil {
return nil, err
}
if ns != "" && acc.GetNamespace() != ns {
continue
}
if name != "" && acc.GetName() != name {
continue
}
res = append(res, obj)
}
return res, nil
}
```
When `name` is empty, `name != "" && acc.GetName() != name` condition is false and thus `obj` is consider as a fit.

If a cache was already synced, cache.WaitForCacheSync would
always take 100ms to complete because the PollUntil method will
sleep first before checking the condition. Switching to
PollImmediateUntil will ensure already synced caches will return
immediately. For code that has, for example, 20 informers, the time
to check the cache was in sync would take at least 2 seconds, but with
this change it can be as fast as you can actually load the data.

Golang automatically enables transport level gzip, but local network
clients may wish to disable it for better CPU usage and lower latency
(scheduler, controller-manager). Allow DisableCompression on rest.Config
to modify the underlying transport. This impacts the transport cache,
but it is expected that most clients connecting to the same servers
within a process will have the same compression config.

There was some weird queuing going on. The queue was implement by
spawning goroutines that would block on the "ticketer" until it was
their turn to write to the output channel. If N events where in the
watch when the consumer of the watch stopped reading events, N
goroutines would leak. In unit tests of the certificate manager, this
was causing ~10k goroutines to leak.
Fix it with a buffering event processor that uses only one routine and
cancels correctly.

This client exposes operations on generic metadata (get, list, watch, delete)
and allows patch operations. The client always uses protobuf and requests
the server transform the response into the appropriate object. Using this
client simplifies the work of generic controllers by allowing them to treat

data sent as well as allowing protobuf on CRD resources.

Clients are required to handle watch events of type ERROR, so instead
of eating the decoding error we should pass it on to the client. Use
NewGenericServerError with isUnexpectedResponse to indicate that we
didn't get the bytes from the server we were expecting. For watch, the
415 error code is roughly correct and we will return an error to the
client that makes debugging a failure in either server watch or client
machinery much easier.
We do not alter the behavior when it appears the response is an EOF
or other disconnection.

When setting up a port forwarding with the client-go library (using the
`k8s.io/client-go/tools/portforward.PortForwarder`) with a non-defined local
port (i.e. passing `:80` as `ports` parameter to `portforward.New(...)`), a
local port will be assigned dynamically.
Currently, the local port will be _always_ 0 if it was not specified initially.
This is because the assigned local port is only set on a _copy_ of the actual
`ForwardedPort` type that is obtained in a `range` loop. This PR changes this
behaviour to set the local port at the correct instance by passing a pointer
instead of a copy to the relevant functions.

Clean up the code paths that lead to objects being transformed and output with negotiation.
Remove some duplicate code that was not consistent. Now, watch will respond correctly to
Table and PartialObjectMetadata requests. Add unit and integration tests.
When transforming responses to Tables, only the first watch event for a given type will
include the columns. Columns will not change unless the watch is restarted.
Add a volume attachment printer and tighten up table validation error cases.
Disable protobuf from table conversion because Tables don't have protobuf because they
use `interface{}`

The current code simply exits without continuing to renew the lease, which means
participants using a slower lease duration might have to wait multiple minutes
before a new leader is elected. Allow an optional flag to be set on
LeaderElectionConfig that will release the lease when the calling context is
cancelled. Callers *must* ensure their lease guarded code has completed before
the context is cancelled, or other processes may acquire the lease before this
lease has released.
Add an example command that demonstrates how cancellation could be done.
As a convenience to users, make event recorder optional - not all users of the
lock code will need a recorder.

Not every object kind can be registered via tracker .Add() called as
part of SimpleClientset initialization. This is because .Add() relies
on UnsafeGuessKindToResource to convert object kinds into resource
type names, which is broken for some resources. An example of an
affected kind is NetworkAttachmentDefinitions CRD that uses
network-attachment-definitions as its resource type name. When
UnsafeGuessKindToResource is called for this kind, it returns
networkattachmentdefinitions (without dashes).
As per the comment inside .Add, kinds affected by
UnsafeGuessKindToResource deficiencies should instead register objects
using tracker .Create() method. Problem is, current SimpleClientset
struct definition doesn't expose the object tracker in any way, which
makes it impossible to properly register these kinds at all.
To address the issue, this change modifies the definition of
SimpleClientset struct to expose the object tracker used via Tracker()
method.

The rules for address parsing are:
* Explicitly specified addresses must bind successfully
* `localhost` is pinned to `127.0.0.1` and `::1` and at least one of those must bind successfully
This change also makes output of the command consistent
between runs with the same arguments.
Previously the command was using the range via map of addresses
which sometimes was producing different output because the order
of values is not guaranteed in Go.

It's very easy to add glog.Info(config) calls for debugging (or actual

and those tokens will end up in logs or response bodies.
Leaking of those stringified configs compromises the cluster.

Kubernetes-commit: 2299f45f52464beff889fce7be1f66642a92b791
Ensure that bootstrap+clientcert-rotation in the Kubelet can:
1. happen in the background so that static pods aren't blocked by bootstrap
2. collapse down to a single call path for requesting a CSR
3. reorganize the code to allow future flexibility in retrieving bootstrap creds
Fetching the first certificate and later certificates when the kubelet
is using client rotation and bootstrapping should share the same code
path. We also want to start the Kubelet static pod loop before
bootstrapping completes. Finally, we want to take an incremental step
towards improving how the bootstrap credentials are loaded from disk
(potentially allowing for a CLI call to get credentials, or a remote
plugin that better integrates with cloud providers or KSMs).
Reorganize how the kubelet client config is determined. If rotation is
off, simplify the code path. If rotation is on, load the config
from disk, and then pass that into the cert manager. The cert manager
creates a client each time it tries to request a new cert.
Preserve existing behavior where:
1. bootstrap kubeconfig is used if the current kubeconfig is invalid/expired
2. we create the kubeconfig file based on the bootstrap kubeconfig, pointing to
the location that new client certs will be placed
3. the newest client cert is used once it has been loaded

certificate.FileStore only handles (cert, key) combined PEM files. This
PR allows (key, cert), which is what "openssl req -out foo.pem -keyout
foo.pem" generates.
Kubernetes-commit: 4b6a6a1cd5c8df83b3c51a03ecab975b82057489
With the current behavior, when kubelet starts, a `templateChanged`
event is always fired off because it only checks if `getLastRequest`
matches `getTemplate`. The last request only exists in memory and thus
is initially `nil` and can't ever match the current template during
startup.
This causes kubelet to request the signing of a new CSR every time it's
restarted. This commit changes the behavior so that `templateChanged` is
only fired off if the currently template doesn't match both the current
certificate and the last template.

change TRUNCATED to DATA+OMITTED in kubectl config view
**What this PR does / why we need it**:
Based on the discussion in #61573, this PR switches the replacement text for CA certificate data and client certificates and secrets printed using `kubectl config view`. Currently, `REDACTED` is used, which might give a false impression that the data is a secret (which is not true for the public certificates).
This PR changes `REDACTED` to `DATA+OMITTED`. The printed string is the base64 encoded string on the byte stream. Some trickery is involved to print a readable string (refer to [this comment](https://github.com/kubernetes/kubernetes/pull/66023/files#diff-aec000ca3f293c94dcd99b4a9d1c5c3cL86) for more info).

**What this PR does / why we need it**:
Updates github.com/imdario/mergo library to v0.3.5. We were pinned because of a functionality change in the dependency, however, a new function was introduced with similar functionality to the old.
There is apparently some Debian packaging issues (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=878254) because of this. I'm still not clear what those are, unless they are forcing the library to update, as opposed to using our `vendor/`.
That said, this will allow for some of those vendor conflicts to resolve for anyone else who is using client-go, so that's at least worthwhile.

Percent-encode illegal characters in user.Info.Extra keys
This percent-encodes characters in `X-Remote-Extra-` and `Impersonate-Extra-` keys which aren't valid for header names per [RFC 7230](https://tools.ietf.org/html/rfc7230#section-3.2.6) (plus "%" to avoid breaking keys which contain them). The API server then blindly unescapes these keys.
Reviewer note:
Old clients sending keys which were `%`-escaped by the user will have their values unescaped by new API servers. New clients sending keys containing illegal characters (or "%") to old API servers will not have their values unescaped. This version skew incompatibility is a compromise discussed in #63682.
Fixes#63682

**Release note**:
```release-note
action required: the API server and client-go libraries have been fixed to support additional non-alpha-numeric characters in UserInfo "extra" data keys. Both should be updated in order to properly support extra data containing "/" characters or other characters disallowed in HTTP headers.

Add a new conversion path to replace GenericConversionFunc
reflect.Call is very expensive. We currently use a switch block as part of AddGenericConversionFunc to avoid the bulk of top level a->b conversion for our primary types which is hand-written. Instead of having these be handwritten, we should generate them.
The pattern for generating them looks like:
```
scheme.AddConversionFunc(&v1.Type{}, &internal.Type{}, func(a, b interface{}, scope conversion.Scope) error {
return Convert_v1_Type_to_internal_Type(a.(*v1.Type), b.(*internal.Type), scope)
})
```
which matches AddDefaultObjectFunc (which proved out the approach last year). The
conversion machinery should then do a simple map lookup based on the incoming types and invoke the function. Like defaulting, it's up to the caller to match the types to arguments, which we do by generating this code. This bypasses reflect.Call and in the future allows Golang mid-stack inlining to optimize this code.
As part of this change I strengthened registration of custom functions to be generated instead of hand registered, and also strengthened error checking of the generator when it sees a manual conversion to error out. Since custom functions are automatically used by the generator, we don't really have a case for not registering the functions.
Once this is fully tested out, we can remove the reflection based path and the old registration methods, and all conversion will work from point to point methods (whether generated or custom).
Much of the need for the reflection path has been removed by changes to generation (to omit fields) and changes to Go (to make assigning equivalent structs easy).

The default cache for a cachedTokenSource is not always empty. In the
case of commandTokenSource, it contains calling details for the
external command that is used to generate refresh tokens. Persisting
a completely empty cache will thus break ability for the plugin to
obtain refresh tokens. This changes the roundtripper to persist
the default cache instead of assuming an empty map.

Derive kubelet serving certificate CSR template from node status addresses
xref https://github.com/kubernetes/features/issues/267fixes#55633
Builds on https://github.com/kubernetes/kubernetes/pull/65587
* Makes the cloud provider authoritative when recording node status addresses
* Makes the node status addresses authoritative for the kube-apiserver determining how to speak to a kubelet (stops paying attention to the hostname label when determining how to reach a kubelet, which was only done to support kubelets < 1.5)
* Updates kubelet certificate rotation to be driven from node status
* Avoids needing to compute node addresses a second time, and differently, in order to request serving certificates.
* Allows the kubelet to react to changes in its status addresses by updating its serving certificate
* Allows the kubelet to be driven by external cloud providers recording node addresses on the node status
test procedure:

track schemes by name for error reporting
Getting an error message about a type not being in the scheme is hard to fix if you don't know which scheme is failing. This adds a name to the scheme which can be set during creation or can be set based on the calling stack. If you use the old constructor a name is generated for you based on the stack. Something like "k8s.io/client-go/dynamic/scheme.go:28" for instance.
Also moves a typer to its point of use. This was debt from previous refactors which I noticed going through.

client-go/examples/fake-client: add doc.go to fix go build warnings
The publishing bot is currently broken (https://github.com/kubernetes/kubernetes/issues/56876#issuecomment-399763681). This is due to the following error:
```

```
The fakeclient package does not have any non-test go files. The test file was added in https://github.com/kubernetes/kubernetes/pull/65291 2 days ago.
This causes `go build` to give a warning: `no non-test Go files in /go-workspace/src/k8s.io/client-go/examples/fake-client`, which breaks the publishing bot. This PR adds a dummy doc.go file in the package to avoid this warning and fix the publishing bot.

Update to rules_go 0.12.1 and gazelle 0.12.0 and perform related cleanups
**What this PR does / why we need it**: my initial intent was to simply update to rules_go 0.12.1 and gazelle 0.12.0.
A few internal changes / deprecations meant that I finally needed to clean up some technical debt. This also fixes#64122.
I've attempted to keep the steps as separate commits to make it easier to review:
1. Disable gazelle proto rule generation; legacy proto rules are deprecated, and we don't (currently) build protos at build time anyway, instead generating them with `hack/update-generated-protobuf.sh` and then checking them in. We can revisit this in the future if we'd like.
2. Remove the legacy `go_default_library_protos` filegroups using [buildozer](https://github.com/bazelbuild/buildtools/tree/master/buildozer). We don't use these, anyway.
3. Update the rules_go bazel workspace dependency to 0.12.1.
4. Vendor gazelle 0.12.0 and update BUILD files with `hack/update-bazel.sh`. This causes a lot of diffs, because `select()`s are no longer used in `srcs` attributes, external tests are folded into non-external tests, and vendored targets get an `importmap` attribute.
5. Set `gazelle:prefix` on `staging/src/BUILD` to make gazelle treat these correctly(ish). This allows us to remove the sed rewrite hack in `hack/update-bazel.sh`.
6. Explicitly set `# gazelle:importmap_prefix k8s.io/kubernetes/vendor` on `vendor/`, so that all vendored dependencies get the right importmap. gazelle 0.12.0 uses the bazel workspace name + `vendor/` as a prefix, which doesn't work with native go. Newer gazelle will use the go prefix (https://github.com/bazelbuild/bazel-gazelle/pull/207), but it's not released yet. Setting this correctly now also fixes later `BUILD` churn.
7. Re-run `hack/update-bazel.sh`. This causes a bunch of diffs, since anything under `staging/src` now uses the `staging/src/` path instead of `vendor/`. (Both would work for bazel, but gazelle uses the former, since `vendor/` uses symlinks.) Also `importmap`s under `vendor/` are fixed.
8. Reformat a few files (using [buildifier](https://github.com/bazelbuild/buildtools/tree/master/buildifier)) to make later diffs easier to read.
9. Rework the `go_genrule` rules to use the new `go_genrule` from https://github.com/kubernetes/repo-infra/pull/72, which is more bazely, since it uses the rules_go `go_path` rule instead of lots of shell.
10. Remove the deprecated `go_prefix` rule from the root BUILD.bazel file.
11. Set `# gazelle:importmap_prefix k8s.io/kubernetes/vendor` on `staging/src` as well, which ensures that these repos are treated as vendored dependencies. (It's basically the bazel-y way of doing the `vendor/k8s.io` symlinks.)
12. Run `hack/update-bazel.sh` one last time to fix all of the `importmap`s under `staging/src`.
Note re: point 6 above - we're pretty much ignoring the `vendor/k8s.io` symlinks entirely now under bazel. Using the `gazelle:prefix` directive ensures these get mapped into the right go importpath, and the `go_path` rule installs these correctly now too.

The fakeclient package does not have any non-test go files. This
causes `go build` to give a warning: `no non-test Go files in ...`.
This also causes the publishing bot to fail.
This PR adds a dummy doc.go file in the package to avoid this warning.

Fix CRD OpenAPI schema
fixes#65243
depends on https://github.com/kubernetes/kube-openapi/pull/84
without this PR, kubectl complains about creating this CRD with a validation schema (which worked in 1.10):
```yaml
apiVersion: apiextensions.k8s.io/v1beta1
kind: CustomResourceDefinition
metadata:
name: resources.mygroup.example.com
spec:
group: mygroup.example.com
version: v1alpha1
scope: Namespaced
names:
plural: resources
singular: resource
kind: Kind
listKind: KindList
validation:
openAPIV3Schema:
properties:
spec:
type: array
items:
type: number
```
> error: error validating "/Users/jliggitt/projects/snippets/crd/crd.yaml": error validating data: [ValidationError(CustomResourceDefinition.spec.validation.openAPIV3Schema.properties.spec.items): unknown field "type" in io.k8s.apiextensions-apiserver.pkg.apis.apiextensions.v1beta1.JSONSchemaPropsOrArray, ValidationError(CustomResourceDefinition.spec.validation.openAPIV3Schema.properties.spec.items): missing required field "Schema" in io.k8s.apiextensions-apiserver.pkg.apis.apiextensions.v1beta1.JSONSchemaPropsOrArray, ValidationError(CustomResourceDefinition.spec.validation.openAPIV3Schema.properties.spec.items): missing required field "JSONSchemas" in io.k8s.apiextensions-apiserver.pkg.apis.apiextensions.v1beta1.JSONSchemaPropsOrArray]; if you choose to ignore these errors, turn validation off with --validate=false
that is because the types used to serialize JSONSchema require custom marshaling/unmarshaling, and the OpenAPI generator was not informed of that, so it produced this:
```json
{
"io.k8s.apiextensions-apiserver.pkg.apis.apiextensions.v1beta1.JSONSchemaPropsOrArray": {
"description": "JSONSchemaPropsOrArray represents a value that can either be a JSONSchemaProps or an array of JSONSchemaProps. Mainly here for serialization purposes.",
"required": [
"Schema",
"JSONSchemas"
],
"properties": {
"JSONSchemas": {
"type": "array",
"items": {
"$ref": "#/definitions/io.k8s.apiextensions-apiserver.pkg.apis.apiextensions.v1beta1.JSONSchemaProps"
}
},
"Schema": {
"$ref": "#/definitions/io.k8s.apiextensions-apiserver.pkg.apis.apiextensions.v1beta1.JSONSchemaProps"
}
}
}
}
```
OpenAPI isn't able to represent oneOf/anyOf types correctly currently. Until it can, we definitely shouldn't publish a schema containing required fields which aren't even part of the JSON serialization. This PR implements custom openapi type functions, which omit the properties/required/schema attributes for four specific JSONSchema types. This allows kubectl to continue creating these objects without complaining.

Re-use private key after failed CSR
**What this PR does / why we need it**:
This fixes a regression introduced in 1.11.
If we create a new key on each CSR, if CSR fails the next attempt will
create a new one instead of reusing previous CSR.
If approver/signer don't handle CSRs as quickly as new nodes come up,
they can pile up and approver would keep handling old abandoned CSRs and
Nodes would keep timing out on startup.

kubeadm: Refactor the Bootstrap Tokens usage in the API types
**What this PR does / why we need it**:
This PR:
- Moves some common, generic Bootstrap Token helpers and constants from `k8s.io/kubernetes/cmd/kubeadm/app/util/token` to `k8s.io/client-go/tools/bootstrap/token/`
- Breaks out the top-level Bootstrap Token fields to a dedicated `BootstrapToken` struct with helper functions.
- Instead of representing the Bootstrap Token as a plain `string`, there is now a wrapper struct `BootstrapTokenString` that can marshal/unmarshal correctly and supports validation on create, and splitting up the full token in the ID/Secret parts automatically.
- Makes kubeadm support multiple Bootstrap Tokens automatically by supporting a slice of `BootstrapToken` in the `MasterConfiguration` API object
- Consolidates the place for kubeadm to create token-related flags in an `options` package
- Supports automatic conversion from the `v1alpha1` to `v1alpha2` API
- Adds support to set token expiration directly instead of setting a TTL (Expiration and TTL are mutually exclusive)
- Removes the old `TokenDiscovery` struct we're not using anymore inside of kubeadm

**Release note**:
```release-note
[action required] kubeadm: The Token-related fields in the `MasterConfiguration` object have now been refactored. Instead of the top-level `.Token`, `.TokenTTL`, `.TokenUsages`, `.TokenGroups` fields, there is now a `BootstrapTokens` slice of `BootstrapToken` objects that support the same features under the `.Token`, `.TTL`, `.Usages`, `.Groups` fields.

Use Dial with context
**What this PR does / why we need it**:
`net/http/Transport.Dial` field is deprecated:
```go
// DialContext specifies the dial function for creating unencrypted TCP connections.
// If DialContext is nil (and the deprecated Dial below is also nil),
// then the transport dials using package net.
DialContext func(ctx context.Context, network, addr string) (net.Conn, error)
// Dial specifies the dial function for creating unencrypted TCP connections.
//
// Deprecated: Use DialContext instead, which allows the transport
// to cancel dials as soon as they are no longer needed.
// If both are set, DialContext takes priority.
Dial func(network, addr string) (net.Conn, error)
```
This PR switches all `Dial` usages to `DialContext`. Fixes#63455.

**Release note**:
```release-note
HTTP transport now uses `context.Context` to cancel dial operations. k8s.io/client-go/transport/Config struct has been updated to accept a function with a `context.Context` parameter. This is a breaking change if you use this field in your code.

category expansion can only come from the server
A couple release ago we moved category expansion to the server instead of hardcoding it in the client.

simplify api registration
The current registration and groupmeta is only use to determine a preferred ordering to versions. The scheme already knows about all versions, so this simply makes that knowledge official. After doing that, the announce, registered, and apimachinery/pkg/apimachinery all drop out.
With this change we'll be able to create `install` packages for each external apigroup that accept a scheme and have suggested orderings. This will make it possible to close the consistency gap with kubectl, client, and apiserver.

eliminate indirection from type registration
Some years back there was a partial attempt to revamp api type registration, but the effort was never completed and this was before we started splitting schemes. With separate schemes, the idea of partial registration no longer makes sense. This pull starts removing cruft from the registration process and pulls out a layer of indirection that isn't needed.

make a simple dynamic client that is easy to use
The dynamic client has annoyed me for the last time! The existing one takes arguments at odd levels, requires lots of information to instantiate, does some weird pool thing, and uses unusual types. This creates an interface like this:
```go
type DynamicInterface interface {
ClusterResource(resource schema.GroupVersionResource) DynamicResourceInterface
NamespacedResource(resource schema.GroupVersionResource, namespace string) DynamicResourceInterface
}
type DynamicResourceInterface interface {
Create(obj *unstructured.Unstructured) (*unstructured.Unstructured, error)
Update(obj *unstructured.Unstructured) (*unstructured.Unstructured, error)
UpdateStatus(obj *unstructured.Unstructured) (*unstructured.Unstructured, error)
Delete(name string, options *metav1.DeleteOptions) error
DeleteCollection(options *metav1.DeleteOptions, listOptions metav1.ListOptions) error
Get(name string, options metav1.GetOptions) (*unstructured.Unstructured, error)
List(opts metav1.ListOptions) (*unstructured.UnstructuredList, error)
Watch(opts metav1.ListOptions) (watch.Interface, error)
Patch(name string, pt types.PatchType, data []byte, subresources ...string) (*unstructured.Unstructured, error)
}
```
You create it from just a `rest.Config`, no mapper, no path resolving func, no trying to set up codecs ahead of time, no unnecessary pool. It just works.
I updated the namespace controller to use it and I updated the existing dynamic client to leverage it so that I get all their tests for "free".
@kubernetes/sig-api-machinery-pr-reviews
@liggitt @smarterclayton @bparees @sttts @ironcladlou I know each of us has struggled with the dynamic client in our time.
@lavalamp @caesarxuchao This is vastly simplifying. I'm eager to drop the old `ClientPool`. client-go will technically have another incompatible semver this release. I'm up for changing it in tree.
```release-note

When bootstrapping a client cert, store it with other client certs
The kubelet uses two different locations to store certificates on
initial bootstrap and then on subsequent rotation:
* bootstrap: certDir/kubelet-client.(crt|key)
* rotation: certDir/kubelet-client-(DATE|current).pem
Bootstrap also creates an initial node.kubeconfig that points to the
certs. Unfortunately, with short rotation the node.kubeconfig then
becomes out of date because it points to the initial cert/key, not the
rotated cert key.
Alter the bootstrap code to store client certs exactly as if they would
be rotated (using the same cert Store code), and reference the PEM file
containing cert/key from node.kubeconfig, which is supported by kubectl
and other Go tooling. This ensures that the node.kubeconfig continues to
be valid past the first expiration.
Example:
```
bootstrap:
writes to certDir/kubelet-client-DATE.pem and symlinks to certDir/kubelet-client-current.pem
writes node.kubeconfig pointing to certDir/kubelet-client-current.pem
rotation:
writes to certDir/kubelet-client-DATE.pem and symlinks to certDir/kubelet-client-current.pem
```
This will also allow us to remove the wierd "init store with bootstrap cert" stuff, although I'd prefer to do that in a follow up.
@mikedanese @liggitt as per discussion on Slack today
```release-note
The `--bootstrap-kubeconfig` argument to Kubelet previously created the first bootstrap client credentials in the certificates directory as `kubelet-client.key` and `kubelet-client.crt`. Subsequent certificates created by cert rotation were created in a combined PEM file that was atomically rotated as `kubelet-client-DATE.pem` in that directory, which meant clients relying on the `node.kubeconfig` generated by bootstrapping would never use a rotated cert. The initial bootstrap certificate is now generated into the cert directory as a PEM file and symlinked to `kubelet-client-current.pem` so that the generated kubeconfig remains valid after rotation.

deep copy fake client actions to avoid accidental mutation
I just got bit by this downstream. Without a deep copy it is possible accidentally mutate the thing you created, thus invalidating your testing. It's particularly nasty inside of a controller doing a loop on objects, making refs to them, and creating. This works running in an actual process since we serialize and write, but fails unit tests since there is no serialization step.

Use RaceFreeFakeWatcher in ObjectTracker to fix racy watch panics
**What this PR does / why we need it**:
The `FakeWatcher` added to `ObjectTracker` in #57504 allows sends on the result channel after it's closed; for example calling `Stop()` then `Add(obj)` will cause a panic. In my experience this has led to flaky tests when informers and controllers are running.
Replacing `FakeWatcher` with `RaceFreeFakeWatcher` fixes the problem, since `RaceFreeFakeWatcher` ignores additional events that occur after the watcher is stopped. It also panics instead of blocking when the result channel is full, which seems like a more useful behavior in tests than blocking.
I removed the `FakeWatchBufferSize` constant since `RaceFreeFakeWatcher` doesn't take a buffer size argument anymore. This seems fine since the `DefaultChanSize` constant is close to the `FakeWatchBufferSize` value (100 vs 128).
**Special notes for your reviewer**:
I can provide a minimal repro of a flaky test caused by the earlier behavior if necessary.
**Release note**:

The FakeWatcher allows sends on the result channel after it's closed,
for example calling Stop() then Add() will panic. RaceFreeFakeWatcher
checks whether the watcher is stopped before attempting to send. It also
panics instead of blocking when the result channel is full.

Remove dep-reviewers
**What this PR does / why we need it**:
The dep-reviewers group seems to get assigned PRs early the the review process. However, most code changes should be reviewed in the importing part of the code base first, and then assigned to an approver after.
By removing the reviewers group, the approvers plugin will still suggest assigning to an approver, but won't assign for review when the PR is initially opened.

Serve OpenAPI spec with single /openapi/v2 endpoint
**What this PR does / why we need it**:
We are deprecating format-separated endpoints (`/swagger.json`, `/swagger-2.0.0.json`, `/swagger-2.0.0.pb-v1`, `/swagger-2.0.0.pb-v1.gz`) for OpenAPI spec, and switching to a single `/openapi/v2` endpoint in Kubernetes 1.10. The design doc and deprecation process are tracked at: https://docs.google.com/document/d/19lEqE9lc4yHJ3WJAJxS_G7TcORIJXGHyq3wpwcH28nU
Requested format is specified by setting HTTP headers
header | possible values
-- | --
Accept | `application/json`, `application/com.github.proto-openapi.spec.v2@v1.0+protobuf`
Accept-Encoding | `gzip`
This PR changes dynamic_client (and kubectl as a result) to use the new endpoint. The old endpoints will remain in 1.10 and 1.11, and get removed in 1.12.

Split self-signed cert and CA
The key usage limitation of TLS Server Auth makes the cert invalid as a CA.
This switches to generate a single-use CA, uses it to sign the serving cert, then appends the CA to the cert bytes.
* allows a client to continue to reference the cert file as a trust bundle, which now contains a valid CA cert
* continues to keep the generated certificate valid only for serving purposes

apiextensions: add subresources for custom resources
Fixes#38113Fixes#58778
**Related**:
- Proposal: https://github.com/kubernetes/community/pull/913
- For custom resources to work with `kubectl scale`: https://github.com/kubernetes/kubernetes/pull/58283
**Add types**:
- Add `CustomResourceSubResources` type to CRD.
- Fix proto generation for `CustomResourceSubResourceStatus`: https://github.com/kubernetes/kubernetes/pull/55970.
- Add feature gate for `CustomResourceSubResources`.
- Update CRD strategy: if feature gate is disabled, this feature is dropped (i.e. set to `nil`).
- Add validation for `CustomResourceSubResources`:
- `SpecReplicasPath` should not be empty and should be a valid json path under `.spec`. If there is no value under the given path in the CustomResource, the `/scale` subresource will return an error on GET.
- `StatusReplicasPath` should not be empty and should be a valid json path under `.status`. If there is no value under the given path in the CustomResource, the status replica value in the /scale subresource will default to 0.
- If present, `LabelSelectorPath` should be a valid json path. If there is no value under `LabelSelectorPath` in the CustomResource, the status label selector value in the `/scale` subresource will default to the empty string.
- `ScaleGroupVersion` should be `autoscaling/v1`.
- If `CustomResourceSubResources` is enabled, only `properties` is allowed under the root schema for CRD validation.
**Add status and scale subresources**:
- Use helper functions from `apimachinery/pkg/apis/meta/v1/unstructured/helpers.go`.
- Improve error handling: https://github.com/kubernetes/kubernetes/pull/56563, https://github.com/kubernetes/kubernetes/pull/58215.
- Introduce Registry interface for storage.
- Update storage:
- Introduce `CustomResourceStorage` which acts as storage for the custom resource and its status and scale subresources. Note: storage for status and scale is only enabled when the feature gate is enabled _and_ the respective fields are enabled in the CRD.
- Introduce `StatusREST` and its `New()`, `Get()` and `Update()` methods.
- Introduce `ScaleREST` and its `New()`, `Get()` and `Update()` methods.
- Get and Update use the json paths from the CRD and use it to return an `autoscaling/v1.Scale` object.
- Update strategy:
- In `PrepareForCreate`,
- Clear `.status`.
- Set `.metadata.generation` = 1
- In `PrepareForUpdate`,
- Do not update `.status`.
- If both the old and new objects have `.status` and it is changed, set it back to its old value.
- If the old object has a `.status` but the new object doesn't, set it to the old value.
- If old object did not have a `.status` but the new object does, delete it.
- Increment generation if spec changes i.e. in the following cases:
- If both the old and new objects had `.spec` and it changed.
- If the old object did not have `.spec` but the new object does.
- If the old object had a `.spec` but the new object doesn't.
- In `Validate` and `ValidateUpdate`,
- ensure that values at `specReplicasPath` and `statusReplicasPath` are >=0 and < maxInt32.
- make sure there are no errors in getting the value at all the paths.
- Introduce `statusStrategy` with its methods.
- In `PrepareForUpdate`:
- Do not update `.spec`.
- If both the old and new objects have `.spec` and it is changed, set it back to its old value.
- If the old object has a `.spec` but the new object doesn't, set it to the old value.
- If old object did not have a `.spec` but the new object does, delete it.
- Do not update `.metadata`.
- In `ValidateStatusUpdate`:
- For CRD validation, validate only under `.status`.
- Validate value at `statusReplicasPath` as above. If `labelSelectorPath` is a path under `.status`, then validate it as well.
- Plug into the custom resource handler:
- Store all three storage - customResource, status and scale in `crdInfo`.
- Use the storage as per the subresource in the request.
- Use the validator as per the subresource (for status, only use the schema for `status`, if present).
- Serve the endpoint as per the subresource - see `serveResource`, `serveStatus` and `serveScale`.
- Update discovery by adding the `/status` and `/scale` resources, if enabled.
**Add tests**:
- Add unit tests in `etcd_test.go`.
- Add integration tests.
- In `subresources_test.go`, use the [polymporphic scale client](https://github.com/kubernetes/kubernetes/tree/master/staging/src/k8s.io/client-go/scale) to get and update `Scale`.
- Add a test to check everything works fine with yaml in `yaml_test.go`.
**Release note**:
```release-note
`/status` and `/scale` subresources are added for custom resources.

Cap how long the kubelet waits when it has no client cert
If we go a certain amount of time without being able to create a client
cert and we have no current client cert from the store, exit. This
prevents a corrupted local copy of the cert from leaving the Kubelet in a
zombie state forever. Exiting allows a config loop outside the Kubelet
to clean up the file or the bootstrap client cert to get another client
cert.
Five minutes is a totally arbitary timeout, judged to give enough time for really slow static pods to boot.
@mikedanese
```release-note
Set an upper bound (5 minutes) on how long the Kubelet will wait before exiting when the client cert from disk is missing or invalid. This prevents the Kubelet from waiting forever without attempting to bootstrap a new client credentials.

oidc authentication: switch to v2 of coreos/go-oidc
Switch to v2 of [coreos/go-oidc](https://github.com/coreos/go-oidc), which uses square/go-jose to verify tokens and supports more signing algorithms.
Most of this PR removes dependencies used by the older version of github.com/coreos/go-oidc, and updates vendor files.
This PR has been tested against tokens issued by Okta, Google, and CoreOS's dex.
Closes https://github.com/kubernetes/kubernetes/issues/57806
```release-note
kube-apiserver: the OpenID Connect authenticator can now verify ID Tokens signed with JOSE algorithms other than RS256 through the --oidc-signing-algs flag.
kube-apiserver: the OpenID Connect authenticator no longer accepts tokens from the Google v3 token APIs, users must switch to the "https://www.googleapis.com/oauth2/v4/token" endpoint.

Introduce PodSecurityPolicy in the policy/v1beta1 API group
Types/constants are completely the same as in `extensions/v1beta1` except that they are located outside of the `extensions` API group.
**What this PR does / why we need it**:
This is the first step for migrating PSP-related stuff away of `extensions` group. See #43214 for more information.
Also it related to https://github.com/kubernetes/features/issues/5
**Example**:
```console
$ cat restricted2.yaml
apiVersion: policy/v1beta1
kind: PodSecurityPolicy
metadata:
name: restricted2
...
$ kubectl create -f restricted.yaml
podsecuritypolicy "restricted2" created
$ kubectl get psp restricted2 -o yaml
apiVersion: extensions/v1beta1
kind: PodSecurityPolicy
...
```
**Release note**:
```release-note
The `PodSecurityPolicy` API has been moved to the `policy/v1beta1` API group. The `PodSecurityPolicy` API in the `extensions/v1beta1` API group is deprecated and will be removed in a future release.

Remove unused DeltaFIFO compressor argument to NewDeltaFIFO
Nobody uses it; the one or two older users from 1.4/1.5 timeframe
were removed for 1.6. It's also poorly understood and the sole
example is in the testcases, and it's pretty incomplete.
If anyone really wants compression, they can revert this PR.
Earlier pull was https://github.com/kubernetes/kubernetes/pull/43475 which was blocked on some downstream users, which have now removed their usage of the compressor.

* The OpenStack auth config from is now read from the client config. If the client config is not available, it falls back to reading from the environment variables.
* The in-tree support for openstack credentials is now deprecated. Please use the `client-keystone-auth` from the cloud-provider-openstack repository. Details on how to use this new capability is documented [here](https://github.com/kubernetes/cloud-provider-openstack/blob/master/docs/using-client-keystone-auth.md)
* 406 mime-type errors are now tolerated while attempting to load new openapi schema. This improves compatibility with older servers when creating/updating API objects.
* Support for `alpha.kubernetes.io/nvidia-gpu` resource which was deprecated in 1.10 is removed. Please use the resource exposed by `DevicePlugins` instead (`nvidia.com/gpu`).
* Alpha annotation for `PersistentVolume` node affinity has been removed. Update your `PersistentVolume`s to use the beta `PersistentVolume.nodeAffinity` field before upgrading.
*`Node.Spec.ConfigSource.ConfigMap.KubeletConfigKey` must be specified when using dynamic Kubelet config to tell the Kubelet which key of the `ConfigMap` identifies its config file.
* The `GitRepo` volume type is deprecated. To provision a container with a git repo, mount an `EmptyDir` into an `InitContainer` that clones the repo using git, then mount the `EmptyDir` into the Pod's container.
* The Sysctls experimental feature has been promoted to beta (enabled by default via the `Sysctls` feature flag). `PodSecurityPolicy` and `Pod` objects now have fields for specifying and controlling sysctls. Alpha sysctl annotations will be ignored by 1.11+ kubelets. All alpha sysctl annotations in existing deployments must be converted to API fields to be effective.
* The annotation `service.alpha.kubernetes.io/tolerate-unready-endpoints` is deprecated. Users should use `Service.spec.publishNotReadyAddresses` instead.
* Default mount propagation has changed from `HostToContainer` (`rslave` in Linux terminology) to `None` (`private`) to match the behavior in 1.9 and earlier releases. `HostToContainer` as a default caused regressions in some pods.
* Google Cloud Service Account email addresses can now be used in RBAC Role bindings since the default scopes now include the `userinfo.email` scope. This is a breaking change if the numeric uniqueIDs of the Google service accounts were being used in RBAC role bindings. The behavior can be overridden by explicitly specifying the scope values as comma-separated string in the `users[*].config.scopes` field in the `KUBECONFIG` file.
* [k8s.io/api] `VolumeScheduling` and `LocalPersistentVolume` features are beta and enabled by default. The PersistentVolume NodeAffinity alpha annotation is deprecated and will be removed in a future release.
* [k8s.io/api] The `PodSecurityPolicy` API has been moved to the `policy/v1beta1` API group. The `PodSecurityPolicy` API in the `extensions/v1beta1` API group is deprecated and will be removed in a future release.
* [k8s.io/api] `v1.Pod` now has a field `ShareProcessNamespace` to configure whether a single process namespace should be shared between all containers in a pod. This feature is in alpha preview.
* [k8s.io/apimachinery] The `meta.k8s.io/v1alpha1` objects for retrieving tabular responses from the server (`Table`) or fetching just the `ObjectMeta` for an object (as `PartialObjectMetadata`) are now beta as part of `meta.k8s.io/v1beta1`. Clients may request alternate representations of normal Kubernetes objects by passing an `Accept` header like `application/json;as=Table;g=meta.k8s.io;v=v1beta1` or `application/json;as=PartialObjectMetadata;g=meta.k8s.io;v1=v1beta1`. Older servers will ignore this representation or return an error if it is not available. Clients may request fallback to the normal object by adding a non-qualified mime-type to their `Accept` header like `application/json` - the server will then respond with either the alternate representation if it is supported or the fallback mime-type which is the normal object response.

### How to get it
You can use `go get k8s.io/client-go/...` to get client-go, but **you will get
the unstable master branch** and `client-go`'s vendored dependencies will not be
added to your `$GOPATH`. So we think most users will want to use a dependency
management system. See [INSTALL.md](/INSTALL.md) for detailed instructions.
To get the latest version, use go1.16+ and fetch using the `go get` command. For example:
```
go get k8s.io/client-go@latest
```
To get a specific version, use go1.11+ and fetch the desired version using the `go get` command. For example:
```
go get k8s.io/client-go@v0.20.4
```
See [INSTALL.md](/INSTALL.md) for detailed instructions and troubleshooting.

### Dependency management
If your application depends on a package that client-go depends on, and you let the Go compiler find the dependency in `GOPATH`, you will end up with duplicated dependencies: one copy from the `GOPATH`, and one from the vendor folder of client-go. This will cause unexpected runtime error like flag redefinition, since the go compiler ends up importing both packages separately, even if they are exactly the same thing. If this happens, you can either
* run `godep restore` ([godep](https://github.com/tools/godep)) in the client-go/ folder, then remove the vendor folder of client-go. Then the packages in your GOPATH will be the only copy
* or run `godep save` in your application folder to flatten all dependencies.
For details on how to correctly use a dependency management for installing client-go, please see [INSTALL.md](INSTALL.md).
### Contributing code
Please send pull requests against the client packages in the Kubernetes main [repository](https://github.com/kubernetes/kubernetes). Changes in the staging area will be published to this repository every day.
