Fix resize of filesystems in puppet logical_volume

    After system reinstalls there is stale data on the disk
    and puppet fails when resizing, reporting some wrong filesystem
    types. In our case docker-lv was reported as drbd when
    it should have been xfs.

    This problem was solved in some cases e.g:
    when doing a live fs resize we wipe the last 10MB
    at the end of partition:
    https://opendev.org/starlingx/stx-puppet/src/branch/master/puppet-manifests/src/modules/platform/manifests/filesystem.pp#L146

    Our issue happened here:
    https://opendev.org/starlingx/stx-puppet/src/branch/master/puppet-manifests/src/modules/platform/manifests/filesystem.pp#L65
    Resize can happen at unlock when a bigger size is detected for the
    filesystem and the 'logical_volume' will resize it.
    To fix this we have to wipe the last 10MB of the partition after the
    'lvextend' cmd in the 'logical_volume' module.

Tested the following scenarios:

B&R on SX with default sizes of filesystems and cgts-vg.

B&R on SX with with docker-lv of size 50G, backup-lv also 50G and
cgts-vg with additional physical volumes:

    - name: cgts-vg
        physicalVolumes:
        - path: /dev/disk/by-path/pci-0000:00:0d.0-ata-1.0
        size: 50
        type: partition
        - path: /dev/disk/by-path/pci-0000:00:0d.0-ata-1.0
        size: 30
        type: partition
        - path: /dev/disk/by-path/pci-0000:00:0d.0-ata-3.0
        type: disk

B&R on DX system with backup of size 70G and cgts-vg
with additional physical volumes:

    physicalVolumes:
    - path: /dev/disk/by-path/pci-0000:00:0d.0-ata-1.0
        size: 50
        type: partition
    - path: /dev/disk/by-path/pci-0000:00:0d.0-ata-1.0

Execute once the ceph services script on AIO

    The MTC client manages ceph services via ceph.sh which
    is installed on all node types in
    /etc/service.d/{controller,worker,storage}/ceph.sh

    Since the AIO controllers have both controller and worker
    personalities, the MTC client will execute the ceph script
    twice (/etc/service.d/worker/ceph.sh,
    /etc/service.d/controller/ceph.sh).
    This behavior will generate some issues.

We fix this by exiting the ceph script if it is the one from
/etc/services.d/worker on AIO systems.

Revert "Remove recover operations to "restart-on-reboot" pods"
    
    This reverts commit 8abcbf6fb1951b25e9964933558b75b9aff88135.
    
    Reason for revert:
    
    After performing a backup and restore on an AIO-SX system, SRIOV pods do
    not return to a running state and are instead stuck in "container
    creating". The workaround for this is to restart SRIOV pods when the
    system unlocks.
    
    Reverting this commit to allow users to label SRIOV pods and have them
    restarted by k8s-pod-recovery. Labelled pods will be restarted by
    k8s-pod-recovery and will be running after backup and restore is
    completed.
    
    This change has been tested by performing backup and restore on an
    AIO-SX system. SRIOV pods now come up correctly when labelled with
    restart-on-reboot=true

    the tiller pod over a swact when the postgres DB/server moves from one
    controller to the other.
    
    This will help guarantee that the tiller connection is always
    re-established if the connectivity to the postgres backend fails.

Armada: Fix tiller stuck connecting to postgres database
    
    Tiller may start executing before IPv6 network is fully initialized.
    This will result in tiller not being fully functional.
    The liveness probe will detect that tiller didn't start properly and
    restart it. But this might happen an unlimited number of times in a row.
    
    Wait until ping is succesful to the ip of the postgres database.
    This ensures that networking finished setting up.
    Credits to Cole Walker <cole.walker@windriver.com> for proposing the
    idea.

    one containing that change.
    
    Removing patches 0002 and 0003 since the commits are already on
    the armada code at this version.

systemd: Prevent excessive /proc/1/mountinfo reparsing
    
    Backport the patches for this issue:
    https://bugzilla.redhat.com/show_bug.cgi?id=1819868
    
    We met such an issue:
    When testing a large number of pods (> 230), occasionally observed a
    number of issues related to systemd process:
        systemd ran continually 90-100% cpu usage
        systemd memory usage started increasing rapidly (20GB/hour)
        systemctl commands would always timeout (Failed to get properties:
            Connection timed out)
        sm services failed and can't recover: open-ldap,
            registry-token-server, docker-distribution, etcd
        new pods can't start, and got stuck in state ContainerCreating
    
    Those patches work to prevent excessive /proc/1/mountinfo reparsing.
    It has been verified that those patches can improve this performance
    greatly.

Add alternative command to disable lldp agent for i40e devices
    
    LLDP information is not available for certain i40e network devices when
    running system host-lldp-neighbor-show.
    
    This is caused by the firmware lldp agent on the devices not getting
    disabled by the i40e-lldp-configure.sh script which is invoked by lldpd.
    
    The command used to disable the firmware lldp agent in the script works
    for some firmware versions found on devices, but not others. This change
    adds an ethtool command to disable the lldp agent which works for these
    other firmware versions.
    
    From testing, the ethtool method is used for firmware versions 5.05 and
    8.10. The sysfs method is used for firmware version 7.10. In all cases,
    the driver version is 2.14.13

add isolcpus device plugin for kubernetes
    
    In order to minimize latency as much as possible, we want to allow
    kubernetes containers to make use of CPUs which have been specified
    as "isolated" via the kernel boot args.
    
    This commit creates an isolcpus device plugin, which detects the isolated
    CPUs and exports them to kubelet via the device plugin API.
    
    See kubernetes/plugins/isolcpus-device-plugin/files/README.md for
    more information on the behaviour and design choices for this commit.
    
    When we move to a newer version of the Intel device plugin manager we
    may be able to simplify some of this.  See the above README.md file
    for details.

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.

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 by I changed them just in case.

fix exclusive CPU alloc being deleted at container restart
    
    The expectation is that exclusive CPU allocations happen at pod
    creation time. When a container restarts, it should not have its
    exclusive CPU allocations removed, and it should not need to
    re-allocate CPUs.
    
    There are a few places in the current code that look for containers
    that have exited and call CpuManager.RemoveContainer() to clean up
    the container.  This will end up deleting any exclusive CPU
    allocations for that container, and if the container restarts within
    the same pod it will end up using the default cpuset rather than
    what should be exclusive CPUs.
    
    Removing those calls and adding resource cleanup at allocation
    time should get rid of the problem.
    
    This should eventually go into upstream 1.18.1, at which point
    we can just revert this commit.

Add kubernetes support for 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, the set of reserved CPUs (including
    both platform and isolated CPUs) will be specified via
    '--reserved-cpus'.  The isolated CPUs will be identified by looking at
    "/sys/devices/system/cpu/isolated" and treated separately from the
    platform CPUs (which are used to run infrastructure pods).
    
    A plugin (outside the scope of this commit) exposes 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.

kubelet cpumanager patches for low-latency
    
    In order to minimize latency as much as possible, kubernetes containers
    require isolation of platform CPUs, isolcpus CPUs, and shared CPUs. For
    Guaranteed pods, we also need to disable CFS quota throttling.
    
    Infrastructure pods are allowed to run on platform CPUs since they're
    basically doing platform work.  This frees up some resources on
    application CPUs for "normal" kubernetes containers.

fix net/http caching of broken persistent connections
    
    The net/http transport code is currently broken, it keeps broken
    persistent connections in the cache if a write error happens during
    h2 handshake.
    
    This is documented in the upstream bug at:
    https://github.com/golang/go/issues/40213
    
    The problem occurs because in the "go" compiler the http2 code is
    imported into http as a bundle, with an additional "http2" prefix
    applied.  This messes up the erringRoundTripper handling because
    the name doesn't match.
    
    The solution is to have the "go" compiler look for an interface
    instead, so we add a new dummy function that doesn't actually do
    anything and then the "go" compiler can check whether the specified
    RoundTripper implements the dummy function.
    
    Specifically for Kubernetes we need to update the http2 code in the
    "vendor" subdirectory.  A separate change is being made in the "go"
    compiler.

Add custom apps in the k8s-pod-recovery service
    
    At startup, there might be pods that are left in unknown states.
    The k8s-pod-recovery service takes care of
    recovering these unknown pods in specific namespaces.
    To fix this for custom apps that are not part of starlingx,
    we modify the service to look into the /etc/k8s-post-recovery.d
    directory for conf files. Any app that needs to be recovered by this
    service will have to create a conf file e.g the app-1 will create
    /etc/k8s-post-recovery.d/APP_1.conf which will contain the following:
    namespace=app-1-namespace

Handle labeled pods after stabilized
    
    Pods that are in a k8s deployment, daemonset, etc can be labeled as
    restart-on-reboot="true", which will automatically cause them to be
    restarted after the worker manifest has completed in an AIO system.
    It may happen, however, that k8s-pod-recovery service is started
    before the pods are scheduled and created at the node the script is
    running on, causing them to be not restarted. The proposed solution is
    to wait for stabilization of labeled pods before restarting them.

    In addition, since the patch dhcp-dhclient_ipv6_prefix.patch set the
    default prefixlen to 128, which is usually the specifications call
    for host address and it doesn't include any on-link information.
    By contrast, 64 indicates that's subnet area, and this vaule is used
    frequently as usual. So we still use the previous value 64.
    As a result we don't need to modify the relevant place where every
    application code needed for the compatibility any more.

Uprev SR-IOV CNI image
    
    This commit uprevs the SR-IOV CNI image to pick up a few bug
    fixes.  Specifically, this commit will allow rate-limiting
    configuration on a VF to be retained after the VF has been
    used by a pod (and pod subsequently deleted).
    
    Testing:
    
    NICs:
    Ethernet Controller X710 for 10GbE SFP+
    Mellanox MT27700 Family [ConnectX-4]
    
    Functional:
    Connectivity testing (kernel + DPDK)
    Devices allocated appropriately to pod
    Rate-limiting information retained after pod deletion

Add: PF Baseband Device config application for ACC100
    
    This introduces PF BBDEV (baseband device) Configuration Application
    "pf_bb_config" and inih. PF BBDEV program accesses the configuration
    space and sets the various parameters through memory-mapped IO
    read/writes. This is needed for Intel ACC100 (Mt Bryce) configuration
    and QMGR related settings.
    
    PF BBDEV requires inih for parsing .INI configuration file. This
    commit adds the inih for static linkage with PF BBDEV.

Revert "dhcp: fix CVE-2019-6470"
    
    This reverts commit 613fbf258f72042f912a1fde5608168b1068db36.
    
    Since this upversioned package updates the prefixlen to 128, and it
    will occur all hosts offline after booting off the controller-0.
    At the same time this issue will block the use of recent loads for
    both development and test activities. So we revert the patch firstly,
    and investigate deeply then send the new review and request of the
    upgraded patch with the appropriate offline fix.

Add conditions to when RBD devices are unmounted
    
    ceph-preshutdown.sh is called as a post operation when docker is
    stopped/restarted. Based on current service dependencies, when docker is
    restarted this will also trigger a restart of containerd.
    
    Puppet manifests will restart containerd and docker for various
    operations both on system boot and during runtime operations when their
    configuration has changed.
    
    This update adds conditions to ensure that the RBD devices are only
    unmounted when the system is shutting down. This avoids the RBD backed
    persistent volumes from being forcibly removed from running pods and
    being remounted read-only during these restart scenarios.

Armada: add configurations for helm sql storage backend
    
    Configmap is the default helmv2 storage backend to store
    release information but its 1MB resource limit prevents
    scaling up stx openstack workers, so we want to use sql
    as helm storage backend.
    
    Update armada chart to support sql storage backend
    configuration for helm/tiller.
