Code Issues Proposed changes

remove support for versions of K8s lower than 1.24

Browse Source 
Remove support for k8s versions 1.23 and lower since they are not
supported. This change removes k8s versions 1.21.8,
1.22.5, 1.23.1 from the build

Test Plan:
Pass: Tested by successfully creating and installing ISO on AIO-SX.
Pass: Verify /usr/local/kubernetes/ doesn't contain k8s versions
1.21.8, 1.22.5 and 1.23.1.
Pass: Perform platform upgrade, then k8s upgrade to v1.26.1.

From 6bf9795d5e0dfc705299381dc902b22d03ded063 Mon Sep 17 00:00:00 2001
From: Tao Wang <tao.wang@windriver.com>
Date: Tue, 25 Jan 2022 19:23:43 -0500
Subject: [PATCH] kubernetes: make isolcpus allocation SMT-aware
Enhance isolcpus support in Kubernetes to allocate isolated SMT
siblings to the same container when SMT/HT is enabled on the host.
As it stands, the device manager code in Kubernetes is not SMT-aware
(since normally it doesn't deal with CPUs). However, StarlingX
exposes isolated CPUs as devices and if possible we want to allocate
all SMT siblings from a CPU core to the same container in order to
minimize cross- container interference due to resource contention
within the CPU core.
The solution is basically to take the list of isolated CPUs and
re-order it so that the SMT siblings are next to each other. That
way the existing resource selection code will allocate the siblings
together. As an optimization, if it is known that an odd number
of isolated CPUs are desired, a singleton SMT sibling will be
inserted into the list to avoid breaking up sibling pairs.

Subject: [PATCH 6/7] enable support for kubernetes to ignore isolcpus
The normal mechanisms for allocating isolated CPUs do not allow
a mix of isolated and exclusive CPUs in the same container. In
order to allow this in *very* limited cases where the pod spec
is known in advance we will add the ability to disable the normal
isolcpus behaviour.
If the file "/etc/kubernetes/ignore_isolcpus" exists, then kubelet
will basically forget everything it knows about isolcpus and just
treat them like regular CPUs.
The admin user can then rely on the fact that CPU allocation is
deterministic to ensure that the isolcpus they configure end up being
allocated to the correct pods.

Subject: [PATCH 5/7] kubeadm: create platform pods with zero CPU resources
We want to specify zero CPU resources when creating the manifests
for the static platform pods, as a workaround for the lack of
separate resource tracking for platform resources.
We also specify zero CPU resources for the coredns deployment.
manifests.go appears to be the main file for this, not sure if the
others are used but I changed them just in case.

Subject: [PATCH 1/7] kubelet cpumanager disable CFS quota throttling for
Guaranteed pods
This disables CFS CPU quota to avoid performance degradation due to
Linux kernel CFS quota implementation. Note that 4.18 kernel attempts
to solve the CFS throttling problem, but there are reports that it is
not completely effective.
This disables CFS quota throttling for Guaranteed pods for both
parent and container cgroups by writing -1 to cgroup cpu.cfs_quota_us.
Disabling has a dramatic latency improvement for HTTP response times.
This patch is refactored in 1.21.3 due to new internal_container_lifecycle
framework. We leverage the same mechanism to set Linux resources as:
cpu manager: specify the container CPU set during the creation
(commit 38dc7509f862f081828e7d9167107b8c6e98ea23).

Subject: [PATCH 3/7] kubelet cpumanager infrastructure pods use system
reserved CPUs
This assigns system infrastructure pods to the "reserved" cpuset
to isolate them from the shared pool of CPUs.
Infrastructure pods include any pods that belong to the kube-system,
armada, cert-manager, vault, platform-deployment-manager, portieris,
notification, flux-helm or metrics-server namespaces.
The implementation is a bit simplistic, it is assumed that the
"reserved" cpuset is large enough to handle all infrastructure pods
CPU allocations.
This also prevents infrastucture pods from using Guaranteed resources.

Subject: [PATCH 4/7] kubelet cpumanager introduce concept of isolated CPUs
This introduces the concept of "isolated CPUs", which are CPUs that
have been isolated at the kernel level via the "isolcpus" kernel boot
parameter.
When starting the kubelet process, two separate sets of reserved CPUs
may be specified. With this change CPUs reserved via
'--system-reserved=cpu' will be used for infrastructure pods while the
isolated CPUs should be reserved via '--kube-reserved=cpu' to cause
kubelet to skip over them for "normal" CPU resource tracking. The
kubelet code will double-check that the specified isolated CPUs match
what the kernel exposes in "/sys/devices/system/cpu/isolated".
A plugin (outside the scope of this commit) will expose the isolated
CPUs to kubelet via the device plugin API.
If a pod specifies some number of "isolcpus" resources, the device
manager will allocate them. In this code we check whether such
resources have been allocated, and if so we set the container cpuset to
the isolated CPUs. This does mean that it really only makes sense to
specify "isolcpus" resources for best-effort or burstable pods, not for
guaranteed ones since that would throw off the accounting code. In
order to ensure the accounting still works as designed, if "isolcpus"
are specified for guaranteed pods, the affinity will be set to the
non-isolated CPUs.
This patch was refactored in 1.21.3 due to upstream API change
node: podresources: make GetDevices() consistent
(commit ad68f9588c72d6477b5a290c548a9031063ac659).
The routine podIsolCPUs() was refactored in 1.21.3 since the API
p.deviceManager.GetDevices() is returning multiple devices with
a device per cpu. The resultant cpuset needs to be the aggregate.

From 38ecddc618a62bc1b73bafd530b45e9bd8cac19e Mon Sep 17 00:00:00 2001
From: Jim Gauld <james.gauld@windriver.com>
Date: Tue, 7 Sep 2021 13:22:41 -0400
Subject: [PATCH 2/7] kubelet cpumanager keep normal containers off reserved
CPUs
When starting the kubelet process, two separate sets of reserved CPUs
may be specified. With this change CPUs reserved via '--system-reserved=cpu'
or '--kube-reserved=cpu' will be ignored by kubernetes itself. A small
tweak to the default CPU affinity ensures that "normal" Kubernetes
pods won't run on the reserved CPUs.

Subject: [PATCH] kubelet: sort isolcpus allocation when SMT enabled
The existing device manager code returns CPUs as devices in unsorted
order. This numerically sorts isolcpus allocations when SMT/HT is
enabled on the host. This logs SMT pairs, singletons, and algorithm
order details to make the algorithm understandable.

From 95b7b6e1ddb25511c67a3d4018f62df1e76ee7bc Mon Sep 17 00:00:00 2001
From: Tao Wang <tao.wang@windriver.com>
Date: Tue, 25 Jan 2022 19:25:45 -0500
Subject: [PATCH] kubernetes: make isolcpus allocation SMT-aware
Enhance isolcpus support in Kubernetes to allocate isolated SMT
siblings to the same container when SMT/HT is enabled on the host.
As it stands, the device manager code in Kubernetes is not SMT-aware
(since normally it doesn't deal with CPUs). However, StarlingX
exposes isolated CPUs as devices and if possible we want to allocate
all SMT siblings from a CPU core to the same container in order to
minimize cross- container interference due to resource contention
within the CPU core.
The solution is basically to take the list of isolated CPUs and
re-order it so that the SMT siblings are next to each other. That
way the existing resource selection code will allocate the siblings
together. As an optimization, if it is known that an odd number
of isolated CPUs are desired, a singleton SMT sibling will be
inserted into the list to avoid breaking up sibling pairs.

Subject: [PATCH 6/7] enable support for kubernetes to ignore isolcpus
The normal mechanisms for allocating isolated CPUs do not allow
a mix of isolated and exclusive CPUs in the same container. In
order to allow this in *very* limited cases where the pod spec
is known in advance we will add the ability to disable the normal
isolcpus behaviour.
If the file "/etc/kubernetes/ignore_isolcpus" exists, then kubelet
will basically forget everything it knows about isolcpus and just
treat them like regular CPUs.
The admin user can then rely on the fact that CPU allocation is
deterministic to ensure that the isolcpus they configure end up being
allocated to the correct pods.

Subject: [PATCH 5/7] kubeadm: create platform pods with zero CPU resources
We want to specify zero CPU resources when creating the manifests
for the static platform pods, as a workaround for the lack of
separate resource tracking for platform resources.
We also specify zero CPU resources for the coredns deployment.
manifests.go appears to be the main file for this, not sure if the
others are used but I changed them just in case.

Subject: [PATCH 1/7] kubelet cpumanager disable CFS quota throttling for
Guaranteed pods
This disables CFS CPU quota to avoid performance degradation due to
Linux kernel CFS quota implementation. Note that 4.18 kernel attempts
to solve the CFS throttling problem, but there are reports that it is
not completely effective.
This disables CFS quota throttling for Guaranteed pods for both
parent and container cgroups by writing -1 to cgroup cpu.cfs_quota_us.
Disabling has a dramatic latency improvement for HTTP response times.
This patch is refactored in 1.21.3 due to new internal_container_lifecycle
framework. We leverage the same mechanism to set Linux resources as:
cpu manager: specify the container CPU set during the creation
(commit 38dc7509f862f081828e7d9167107b8c6e98ea23).

Subject: [PATCH 3/7] kubelet cpumanager infrastructure pods use system
reserved CPUs
This assigns system infrastructure pods to the "reserved" cpuset
to isolate them from the shared pool of CPUs.
Infrastructure pods include any pods that belong to the kube-system,
armada, cert-manager, vault, platform-deployment-manager, portieris,
notification, flux-helm or metrics-server namespaces.
The implementation is a bit simplistic, it is assumed that the
"reserved" cpuset is large enough to handle all infrastructure pods
CPU allocations.
This also prevents infrastucture pods from using Guaranteed resources.

Subject: [PATCH 4/7] kubelet cpumanager introduce concept of isolated CPUs
This introduces the concept of "isolated CPUs", which are CPUs that
have been isolated at the kernel level via the "isolcpus" kernel boot
parameter.
When starting the kubelet process, two separate sets of reserved CPUs
may be specified. With this change CPUs reserved via
'--system-reserved=cpu' will be used for infrastructure pods while the
isolated CPUs should be reserved via '--kube-reserved=cpu' to cause
kubelet to skip over them for "normal" CPU resource tracking. The
kubelet code will double-check that the specified isolated CPUs match
what the kernel exposes in "/sys/devices/system/cpu/isolated".
A plugin (outside the scope of this commit) will expose the isolated
CPUs to kubelet via the device plugin API.
If a pod specifies some number of "isolcpus" resources, the device
manager will allocate them. In this code we check whether such
resources have been allocated, and if so we set the container cpuset to
the isolated CPUs. This does mean that it really only makes sense to
specify "isolcpus" resources for best-effort or burstable pods, not for
guaranteed ones since that would throw off the accounting code. In
order to ensure the accounting still works as designed, if "isolcpus"
are specified for guaranteed pods, the affinity will be set to the
non-isolated CPUs.
This patch was refactored in 1.21.3 due to upstream API change
node: podresources: make GetDevices() consistent
(commit ad68f9588c72d6477b5a290c548a9031063ac659).
The routine podIsolCPUs() was refactored in 1.21.3 since the API
p.deviceManager.GetDevices() is returning multiple devices with
a device per cpu. The resultant cpuset needs to be the aggregate.

From 38ecddc618a62bc1b73bafd530b45e9bd8cac19e Mon Sep 17 00:00:00 2001
From: Jim Gauld <james.gauld@windriver.com>
Date: Tue, 7 Sep 2021 13:22:41 -0400
Subject: [PATCH 2/7] kubelet cpumanager keep normal containers off reserved
CPUs
When starting the kubelet process, two separate sets of reserved CPUs
may be specified. With this change CPUs reserved via '--system-reserved=cpu'
or '--kube-reserved=cpu' will be ignored by kubernetes itself. A small
tweak to the default CPU affinity ensures that "normal" Kubernetes
pods won't run on the reserved CPUs.

Date: Fri, 23 Oct 2020 17:46:10 -0600
Subject: [PATCH 6/7] enable support for kubernetes to ignore isolcpus
The normal mechanisms for allocating isolated CPUs do not allow
a mix of isolated and exclusive CPUs in the same container. In
order to allow this in *very* limited cases where the pod spec
is known in advance we will add the ability to disable the normal
isolcpus behaviour.
If the file "/etc/kubernetes/ignore_isolcpus" exists, then kubelet
will basically forget everything it knows about isolcpus and just
treat them like regular CPUs.
The admin user can then rely on the fact that CPU allocation is
deterministic to ensure that the isolcpus they configure end up being
allocated to the correct pods.

Subject: [PATCH 5/7] kubeadm: create platform pods with zero CPU resources
We want to specify zero CPU resources when creating the manifests
for the static platform pods, as a workaround for the lack of
separate resource tracking for platform resources.
We also specify zero CPU resources for the coredns deployment.
manifests.go appears to be the main file for this, not sure if the
others are used but I changed them just in case.

From 3f69868f7bca99f6875dd4d197b3a974d1b558ed Mon Sep 17 00:00:00 2001

Date: Wed, 22 Sep 2021 10:09:06 -0400
Subject: [PATCH 1/7] kubelet cpumanager disable CFS quota throttling for
Guaranteed pods
This disables CFS CPU quota to avoid performance degradation due to
Linux kernel CFS quota implementation. Note that 4.18 kernel attempts
to solve the CFS throttling problem, but there are reports that it is
not completely effective.
This disables CFS quota throttling for Guaranteed pods for both
parent and container cgroups by writing -1 to cgroup cpu.cfs_quota_us.
Disabling has a dramatic latency improvement for HTTP response times.
This patch is refactored in 1.21.3 due to new internal_container_lifecycle
framework. We leverage the same mechanism to set Linux resources as:
cpu manager: specify the container CPU set during the creation
(commit 38dc7509f862f081828e7d9167107b8c6e98ea23).

From 66f4a61ce77624dcc0b520e01fccacec61dfea37 Mon Sep 17 00:00:00 2001

Subject: [PATCH 3/7] kubelet cpumanager infrastructure pods use system
reserved CPUs
This assigns system infrastructure pods to the "reserved" cpuset
to isolate them from the shared pool of CPUs.
Infrastructure pods include any pods that belong to the kube-system,
armada, cert-manager, vault, platform-deployment-manager, portieris,
notification, flux-helm or metrics-server namespaces.
The implementation is a bit simplistic, it is assumed that the
"reserved" cpuset is large enough to handle all infrastructure pods
CPU allocations.
This also prevents infrastucture pods from using Guaranteed resources.

From f3db147d0a40a6f336e9fa6d737e36366f9adf87 Mon Sep 17 00:00:00 2001

Subject: [PATCH 4/7] kubelet cpumanager introduce concept of isolated CPUs
This introduces the concept of "isolated CPUs", which are CPUs that
have been isolated at the kernel level via the "isolcpus" kernel boot
parameter.
When starting the kubelet process, two separate sets of reserved CPUs
may be specified. With this change CPUs reserved via
'--system-reserved=cpu' will be used for infrastructure pods while the
isolated CPUs should be reserved via '--kube-reserved=cpu' to cause
kubelet to skip over them for "normal" CPU resource tracking. The
kubelet code will double-check that the specified isolated CPUs match
what the kernel exposes in "/sys/devices/system/cpu/isolated".
A plugin (outside the scope of this commit) will expose the isolated
CPUs to kubelet via the device plugin API.
If a pod specifies some number of "isolcpus" resources, the device
manager will allocate them. In this code we check whether such
resources have been allocated, and if so we set the container cpuset to
the isolated CPUs. This does mean that it really only makes sense to
specify "isolcpus" resources for best-effort or burstable pods, not for
guaranteed ones since that would throw off the accounting code. In
order to ensure the accounting still works as designed, if "isolcpus"
are specified for guaranteed pods, the affinity will be set to the
non-isolated CPUs.
This patch was refactored in 1.21.3 due to upstream API change
node: podresources: make GetDevices() consistent
(commit ad68f9588c72d6477b5a290c548a9031063ac659).
The routine podIsolCPUs() was refactored in 1.21.3 since the API
p.deviceManager.GetDevices() is returning multiple devices with
a device per cpu. The resultant cpuset needs to be the aggregate.
The routine NewStaticPolicy was refactored in 1.22.5, adding a new argument
in its signature: cpuPolicyOptions map[string]string. This change is implies
shifting the new arguments(deviceManager, excludeReserved) with one position
to the right.

Subject: [PATCH 2/7] kubelet cpumanager keep normal containers off reserved
CPUs
When starting the kubelet process, two separate sets of reserved CPUs
may be specified. With this change CPUs reserved via '--system-reserved=cpu'
or '--kube-reserved=cpu' will be ignored by kubernetes itself. A small
tweak to the default CPU affinity ensures that "normal" Kubernetes
pods won't run on the reserved CPUs.

Subject: [PATCH] kubelet: sort isolcpus allocation when SMT enabled
The existing device manager code returns CPUs as devices in unsorted
order. This numerically sorts isolcpus allocations when SMT/HT is
enabled on the host. This logs SMT pairs, singletons, and algorithm
order details to make the algorithm understandable.

Subject: [PATCH] kubernetes: make isolcpus allocation SMT-aware
Enhance isolcpus support in Kubernetes to allocate isolated SMT
siblings to the same container when SMT/HT is enabled on the host.
As it stands, the device manager code in Kubernetes is not SMT-aware
(since normally it doesn't deal with CPUs). However, StarlingX
exposes isolated CPUs as devices and if possible we want to allocate
all SMT siblings from a CPU core to the same container in order to
minimize cross- container interference due to resource contention
within the CPU core.
The solution is basically to take the list of isolated CPUs and
re-order it so that the SMT siblings are next to each other. That
way the existing resource selection code will allocate the siblings
together. As an optimization, if it is known that an odd number
of isolated CPUs are desired, a singleton SMT sibling will be
inserted into the list to avoid breaking up sibling pairs.

# This script is intended to be run during platform upgrade.

# - SCTPSupport=true
# - HugePageStorageMediumSize=true
# - TTLAfterFinished=true

# Background:
# HugePageStorageMediumSize is deprecated in Kubernetes 1.22
# SCTPSupport blocks kube-apiserver pod to spawn after control-plane upgrade
# TTLAfterFinished value defaults to true from k8s 1.21

# In other words, it maintains the effect of this commit

From 087dcfa1a84ec38541fa9870937d76b80a707e2c Mon Sep 17 00:00:00 2001

Subject: [PATCH 6/7] enable support for kubernetes to ignore isolcpus
The normal mechanisms for allocating isolated CPUs do not allow
a mix of isolated and exclusive CPUs in the same container. In
order to allow this in *very* limited cases where the pod spec
is known in advance we will add the ability to disable the normal
isolcpus behaviour.
If the file "/etc/kubernetes/ignore_isolcpus" exists, then kubelet
will basically forget everything it knows about isolcpus and just
treat them like regular CPUs.
The admin user can then rely on the fact that CPU allocation is
deterministic to ensure that the isolcpus they configure end up being
allocated to the correct pods.

Subject: [PATCH 5/7] kubeadm: create platform pods with zero CPU resources
We want to specify zero CPU resources when creating the manifests
for the static platform pods, as a workaround for the lack of
separate resource tracking for platform resources.
We also specify zero CPU resources for the coredns deployment.
manifests.go appears to be the main file for this, not sure if the
others are used but I changed them just in case.

Subject: [PATCH 1/7] kubelet cpumanager disable CFS quota throttling for
Guaranteed pods
This disables CFS CPU quota to avoid performance degradation due to
Linux kernel CFS quota implementation. Note that 4.18 kernel attempts
to solve the CFS throttling problem, but there are reports that it is
not completely effective.
This disables CFS quota throttling for Guaranteed pods for both
parent and container cgroups by writing -1 to cgroup cpu.cfs_quota_us.
Disabling has a dramatic latency improvement for HTTP response times.
This patch is refactored in 1.21.3 due to new internal_container_lifecycle
framework. We leverage the same mechanism to set Linux resources as:
cpu manager: specify the container CPU set during the creation
(commit 38dc7509f862f081828e7d9167107b8c6e98ea23).

Subject: [PATCH 3/7] kubelet cpumanager infrastructure pods use system
reserved CPUs
This assigns system infrastructure pods to the "reserved" cpuset
to isolate them from the shared pool of CPUs.
Infrastructure pods include any pods that belong to the kube-system,
armada, cert-manager, vault, platform-deployment-manager, portieris,
notification, flux-helm or metrics-server namespaces.
The implementation is a bit simplistic, it is assumed that the
"reserved" cpuset is large enough to handle all infrastructure pods
CPU allocations.
This also prevents infrastucture pods from using Guaranteed resources.

Subject: [PATCH 4/7] kubelet cpumanager introduce concept of isolated CPUs
This introduces the concept of "isolated CPUs", which are CPUs that
have been isolated at the kernel level via the "isolcpus" kernel boot
parameter.
When starting the kubelet process, two separate sets of reserved CPUs
may be specified. With this change CPUs reserved via
'--system-reserved=cpu' will be used for infrastructure pods while the
isolated CPUs should be reserved via '--kube-reserved=cpu' to cause
kubelet to skip over them for "normal" CPU resource tracking. The
kubelet code will double-check that the specified isolated CPUs match
what the kernel exposes in "/sys/devices/system/cpu/isolated".
A plugin (outside the scope of this commit) will expose the isolated
CPUs to kubelet via the device plugin API.
If a pod specifies some number of "isolcpus" resources, the device
manager will allocate them. In this code we check whether such
resources have been allocated, and if so we set the container cpuset to
the isolated CPUs. This does mean that it really only makes sense to
specify "isolcpus" resources for best-effort or burstable pods, not for
guaranteed ones since that would throw off the accounting code. In
order to ensure the accounting still works as designed, if "isolcpus"
are specified for guaranteed pods, the affinity will be set to the
non-isolated CPUs.
This patch was refactored in 1.21.3 due to upstream API change
node: podresources: make GetDevices() consistent
(commit ad68f9588c72d6477b5a290c548a9031063ac659).
The routine podIsolCPUs() was refactored in 1.21.3 since the API
p.deviceManager.GetDevices() is returning multiple devices with
a device per cpu. The resultant cpuset needs to be the aggregate.
The routine NewStaticPolicy was refactored in 1.22.5, adding a new argument
in its signature: cpuPolicyOptions map[string]string. This change is implies
shifting the new arguments(deviceManager, excludeReserved) with one position
to the right.

Subject: [PATCH 2/7] kubelet cpumanager keep normal containers off reserved
CPUs
When starting the kubelet process, two separate sets of reserved CPUs
may be specified. With this change CPUs reserved via '--system-reserved=cpu'
or '--kube-reserved=cpu' will be ignored by kubernetes itself. A small
tweak to the default CPU affinity ensures that "normal" Kubernetes
pods won't run on the reserved CPUs.

Subject: [PATCH] kubelet: sort isolcpus allocation when SMT enabled
The existing device manager code returns CPUs as devices in unsorted
order. This numerically sorts isolcpus allocations when SMT/HT is
enabled on the host. This logs SMT pairs, singletons, and algorithm
order details to make the algorithm understandable.

From: Tao Wang <tao.wang@windriver.com>

Subject: [PATCH] kubernetes: make isolcpus allocation SMT-aware
Enhance isolcpus support in Kubernetes to allocate isolated SMT
siblings to the same container when SMT/HT is enabled on the host.
As it stands, the device manager code in Kubernetes is not SMT-aware
(since normally it doesn't deal with CPUs). However, StarlingX
exposes isolated CPUs as devices and if possible we want to allocate
all SMT siblings from a CPU core to the same container in order to
minimize cross- container interference due to resource contention
within the CPU core.
The solution is basically to take the list of isolated CPUs and
re-order it so that the SMT siblings are next to each other. That
way the existing resource selection code will allocate the siblings
together. As an optimization, if it is known that an odd number
of isolated CPUs are desired, a singleton SMT sibling will be
inserted into the list to avoid breaking up sibling pairs.

Subject: [PATCH 6/7] enable support for kubernetes to ignore isolcpus
The normal mechanisms for allocating isolated CPUs do not allow
a mix of isolated and exclusive CPUs in the same container. In
order to allow this in *very* limited cases where the pod spec
is known in advance we will add the ability to disable the normal
isolcpus behaviour.
If the file "/etc/kubernetes/ignore_isolcpus" exists, then kubelet
will basically forget everything it knows about isolcpus and just
treat them like regular CPUs.
The admin user can then rely on the fact that CPU allocation is
deterministic to ensure that the isolcpus they configure end up being
allocated to the correct pods.
