04f5b20388 kubelet: Fix the volume manager did't check the device mount state in the actual state of the world before marking the volume as detached. It may cause a pod to be stuck in the Terminating state due to the above issue when it was deleted. 2024-12-03 09:47:51 +08:00

ea299acf97 Ensure that a node's CIDR isn't released until the node is deleted 
Fixes https://github.com/kubernetes/kubernetes/issues/127792

Fixes bug where a node's PodCIDR was released when the node was given a
delete time stamp, but was hanging around due to a finalizer.

2d540ade5f bugfix(scheduler): preemption picks wrong victim node with higher priority pod on it. 
Introducing pdb to preemption had disrupted the orderliness of pods in the victims,
which would leads picking wrong victim node with higher priority pod on it.

dad9c77a74 bugfix: endpoints controller track resource version conrrectly 
The endpoints controller store the resource version of the previous
Endpoints objects to avoid issues related to stale information on the
cache.

However, there can be update operations that succeed without increasing
the resource version, causing the endpoints controller to declare stale
the existing Resource Version and stopping the Endpoints to be updated.

fc5d752394 Restart the init container to not be stuck in created state 
The main sync loop should have created and started the container in one
step. If the init container is in the 'created' state, it's likely that
the container runtime failed to start it. To prevent the container from
getting stuck in the 'created' state, restart it.

8469207728 Avoid SidecarContainers code path for non-sidecar pods 
This fixes a regression in the SidecarContainers feature by minimizing
the impact of the new code path. Use the old code path for pods without
restartable init containers, and apply the new code path only to pods
with restartable init containers.

f520ede814 kube-proxy: initialization wait for service and endpoint handlers synced 
Ensure kube-proxy waits for the services/endpointslices informer
caches to be synced *and* all pre-sync events delivered before
setting isInitialized=true. Otherwise, in clusters with many services,
some services may be missing from svcPortMap when kube-proxy starts
(e.g. during daemonset rollout). This can cause kube-proxy to temporarily
remove service DNAT rules and then skip cleanup of UDP conntrack entries
to a service VIP.

This commit fixes panics if:

- `len(imageStats.ImageFilesystems) == 0`
- `len(imageStats.ContainerFilesystems) == 0`
- `imageStats.ImageFilesystems[0].FsId == nil`
- `imageStats.ContainerFilesystems[0].FsId == nil`
- `imageStats.ImageFilesystems[0].UsedBytes == nil`
- `imageStats.ContainerFilesystems[0].UsedBytes == nil`

It also fixes the wrapped `nil` error for the check: `err != nil ||
imageStats == nil` in case that `imageStats == nil`.
