This is a proof-of-concept of a change we have done in v1.16 to counter the performance regression we saw in v1.16 after 2e2c6c5. The commit message has more details - but this was a huge win in terms of performance, as the normal v1.16 (and onwards) builds can't handle very much policy churn before falling over. This is mostly due to the hot-path in the selectorCache, and the corresponding cascading effect of that lock contention.

This is a proof-of-concept that we can use to start the discussion here.

There is clearly a slight increase in memory usage here since there would be some overlap in what is being indexed - but based on our testing the performance benefit at high scale clearly benefits from this. The changes in the FQDN subsystem by generating a unique identity per fqdn is also increasing the load on the selector cache quite significantly, and this change will help alleviate that.

This code depends on the fact that identities used by local endpoints are correctly upserted to the selectorCache. This was guaranteed in v1.16 and prior, but 36c9bba has partially changed that. Even though that change is not very functional - but it might end up hiding bugs in that upsert mechanism, especially around endpoint restoration, so we need to look into that, since those kinds of bugs can and will lead to memory leaks.

on tests: We of course need to update the tests here, and for now I've just made the basic ones pass. The current tests have loads of assumptions that we have to clean up, so for now we just keep upserting to the two caches.


commit message:

    policy: split selectorCache in two

    This creates two unique selector caches inside the policy repository. We
    do this since the performance after changes in v1.16 caused the selector cache
    to become a lot slower since more data is injected.

    This split takes advantage of the fact that in a cluster where pods,
    identities and unique policies are churned consistently at a given rate r - we
    know that not all aspects are equally expensive. If we then assume these
    will have the cardinality c, we can do some calculations.

    We know that identities and the policies are cluster level and will
    churn at the same rate r, and has the same cardinality c.
    However, we know that on a given node, the churn of identities used by
    local endpoints is pretty small, most likely much smaller than r. The
    same with the cardinality of those identities, that can be at most the
    same number as there are endpoints on a node. We then also know, based
    on the assumption that not all policies match all pods, that not all l3/l4
    {to,from}Endpoints are used by all endpoints. We can then assume that on
    a given node, not all c l3/l4 policies are being used. The same we can
    assume for the churn then, that the change of l3/l4 policies in use at a
    given time on the node, is much smaller than r. This also includes
    policies like FQDN and toCIDR policies, and other types of policies that
    end up in the selector cache today - but the concept is exactly the
    same.

    Based on this - we can split the selector cache in two, where;

    One is used to index:
    - policies from their endpointSelector (high churn rate, high cardinality)
    - identities used by local endpoints (low churn rate, low cardinality)

    And the other one to index:
    - internal l3/l4 policies used by local endpoints (low churn rate, low
      cardinality)
    - all identities (high churn rate, high cardinality)

    All this together, means that we go from a single selector cache that
    indexes a lot of different high churn and high cardinality items - to
    two distinct selector caches that index one high cardinality high churn
    aspect, and one that is low cardinality low churn.

As I understand this the proposal is to use a separate selector cache for tracking policy subject selectors and the identities of local endpoints instead of tracking them in the same shared selector cache as done in 2e2c6c5? Given your experience and analysis this makes sense as it avoids the combination of high cardinality/high churn on subject selectors and high cardinality/high churn on all identities in the cluster.

Haven't looked at the details yet but the overall aim makes sense to me :-)

Thanks for finding out about the performance regression and proposing a fix. I think the approach is sound and really only have nits for naming things, avoiding exposing the new cache to other packages, tightening the test changes, and adding some comments.

Thanks @christarazi and @jrajahalme for the initial review. Give you seem positive towards this, I'll continue to work in it next week. However, first I'd like to fix the existing issues/leaks as mentioned in #42580 (comment). I'll link that PR here when its up.

We use cilium-dbg policy selectors to debug any possible selectorcache bugs. It would be good to update this command to dump subject selectors as well.

Now that all the correctness patches are merged (🥳), lets agree on the new metrics before finishing this patchset; #42872.

Once that is all settled I'll rebase this and make it ready for review again. 😄

Hmm, okay, so I did a quick rebase last week, but now #43279 is applied again - so another set of conflicts. I'll wait for #42872 to rebase this again 🤞

Sorry for the delay. Docs changes look good. I didn't inspect the policy details closely. One minor question around API but it's not blocking from my perspective.

Thanks. I've resolved all comments except for the last discussion point now.

I'll FLUP the metric updates in a separate change to keep it as small as possible. I've also looked at 5710ac4 a fair bit, given its explicit that identity mutations are supported, and wonder if we should support that here as well - or not. I think its fine for now, and we can look into that later.

Guide](https://docs.cilium.io/en/v1.19/operations/upgrade/#upgrade-notes)
for more details.

The full changelog can be found
[here](https://redirect.github.com/cilium/cilium/blob/v1.19/CHANGELOG.md).

Here are some of the highlights:

- 🛡️ **Network Policy**
- 🃏 **Multi-Level DNS Matches**: DNS Policies match pattern now support
a wildcard prefix(*`**.`*) to match multilevel subdomain as pattern
prefix.
([cilium/cilium#43420](https://redirect.github.com/cilium/cilium/pull/43420),
[@&#8203;fristonio](https://redirect.github.com/fristonio))
- 📡 **Match New Protocols**: You can now match VRRP and IGMP protocols
in host firewall rules.

[@&#8203;kyounghunJang](https://redirect.github.com/kyounghunJang))
- ⛔ **Actively Deny Connections**: When Network Policies deny a
connection, Cilium can return ICMPv4 "Destination unreachable" messages
for a friendlier deny.
([cilium/cilium#41406](https://redirect.github.com/cilium/cilium/pull/41406),
[@&#8203;antonipp](https://redirect.github.com/antonipp))
- 🌐 **Select Clusters Explicitly**: When network policy selectors don't
explicitly define a cluster for communication to be allowed, they will
now default to only allowing the local cluster.
([cilium/cilium#40609](https://redirect.github.com/cilium/cilium/pull/40609),

[@&#8203;youngnick](https://redirect.github.com/youngnick))

- 🛣️ **Border Gateway Protocol (BGP)**
- 🔌 **Advertise Addresses from Interfaces**: There's a new Interface BGP
advertisement type that allows advertisement of IPs assigned on local
interfaces. This can be useful for example in multi-homing setups, where
a common node's loopback address can be advertised via multiple BGP
sessions over different network interfaces.
([cilium/cilium#42469](https://redirect.github.com/cilium/cilium/pull/42469),
[@&#8203;rastislavs](https://redirect.github.com/rastislavs))
- ✉️ **Override Source IP addresses**: You can override the
auto-generated BGP session source IP with the IP address applied on the
configured `sourceInterface` to allow binding the BGP connection to the
loopback address which is not tied to the specific physical interface's
lifecycle
([cilium/cilium#42583](https://redirect.github.com/cilium/cilium/pull/42583),
[@&#8203;rastislavs](https://redirect.github.com/rastislavs))
- 🔁 **Withdraw Empty Routes**: Optionally withdraw BGP routes when a
service has 0 endpoints, to allow balancing to a different DC/cluster
with `externalTrafficPolicy=Cluster`
([cilium/cilium#40717](https://redirect.github.com/cilium/cilium/pull/40717),
[@&#8203;oblazek](https://redirect.github.com/oblazek))

Guide](https://docs.cilium.io/en/v1.19/operations/upgrade/#upgrade-notes)
for more details.

The full changelog can be found
[here](https://redirect.github.com/cilium/cilium/blob/v1.19/CHANGELOG.md).

Here are some of the highlights:

- 🛡️ **Network Policy**
- 🃏 **Multi-Level DNS Matches**: DNS Policies match pattern now support
a wildcard prefix(*`**.`*) to match multilevel subdomain as pattern
prefix.
([cilium/cilium#43420](https://redirect.github.com/cilium/cilium/pull/43420),
[@&#8203;fristonio](https://redirect.github.com/fristonio))
- 📡 **Match New Protocols**: You can now match VRRP and IGMP protocols
in host firewall rules.

[@&#8203;kyounghunJang](https://redirect.github.com/kyounghunJang))
- ⛔ **Actively Deny Connections**: When Network Policies deny a
connection, Cilium can return ICMPv4 "Destination unreachable" messages
for a friendlier deny.
([cilium/cilium#41406](https://redirect.github.com/cilium/cilium/pull/41406),
[@&#8203;antonipp](https://redirect.github.com/antonipp))
- 🌐 **Select Clusters Explicitly**: When network policy selectors don't
explicitly define a cluster for communication to be allowed, they will
now default to only allowing the local cluster.

- 🛣️ **Border Gateway Protocol (BGP)**
- 🔌 **Advertise Addresses from Interfaces**: There's a new Interface BGP
advertisement type that allows advertisement of IPs assigned on local
interfaces. This can be useful for example in multi-homing setups, where
a common node's loopback address can be advertised via multiple BGP
sessions over different network interfaces.
([cilium/cilium#42469](https://redirect.github.com/cilium/cilium/pull/42469),
[@&#8203;rastislavs](https://redirect.github.com/rastislavs))
- ✉️ **Override Source IP addresses**: You can override the
auto-generated BGP session source IP with the IP address applied on the
configured `sourceInterface` to allow binding the BGP connection to the
loopback address which is not tied to the specific physical interface's
lifecycle
([cilium/cilium#42583](https://redirect.github.com/cilium/cilium/pull/42583),
[@&#8203;rastislavs](https://redirect.github.com/rastislavs))
- 🔁 **Withdraw Empty Routes**: Optionally withdraw BGP routes when a
service has 0 endpoints, to allow balancing to a different DC/cluster
with `externalTrafficPolicy=Cluster`

[Upgrade
Guide](https://docs.cilium.io/en/v1.19/operations/upgrade/#upgrade-notes)
for more details.

The full changelog can be found
[here](https://redirect.github.com/cilium/cilium/blob/v1.19/CHANGELOG.md).

Here are some of the highlights:

- 🛡️ **Network Policy**
- 🃏 **Multi-Level DNS Matches**: DNS Policies match pattern now support
a wildcard prefix(*`**.`*) to match multilevel subdomain as pattern
prefix.
([cilium/cilium#43420](https://redirect.github.com/cilium/cilium/pull/43420),
[@&#8203;fristonio](https://redirect.github.com/fristonio))
- 📡 **Match New Protocols**: You can now match VRRP and IGMP protocols
in host firewall rules.

[@&#8203;kyounghunJang](https://redirect.github.com/kyounghunJang))
- ⛔ **Actively Deny Connections**: When Network Policies deny a
connection, Cilium can return ICMPv4 "Destination unreachable" messages
for a friendlier deny.
([cilium/cilium#41406](https://redirect.github.com/cilium/cilium/pull/41406),
[@&#8203;antonipp](https://redirect.github.com/antonipp))
- 🌐 **Select Clusters Explicitly**: When network policy selectors don't
explicitly define a cluster for communication to be allowed, they will
now default to only allowing the local cluster.

[@&#8203;nddq](https://redirect.github.com/nddq))
- 👥 **Mutual Authentication**: The out-of-band [Mutual
Authentication](https://docs.cilium.io/en/v1.19/network/servicemesh/mutual-authentication/mutual-authentication/)
feature is now disabled by default, pending community feedback. If you
have a requirement for mTLS, consider trying the new Ztunnel
integration.

- 🛣️ **Border Gateway Protocol (BGP)**
- 🔌 **Advertise Addresses from Interfaces**: There's a new Interface BGP
advertisement type that allows advertisement of IPs assigned on local
interfaces. This can be useful for example in multi-homing setups, where
a common node's loopback address can be advertised via multiple BGP
sessions over different network interfaces.

- ✉️ **Override Source IP addresses**: You can override the
auto-generated BGP session source IP with the IP address applied on the
configured `sourceInterface` to allow binding the BGP connection to the
loopback address which is not tied to the specific physical interface's
lifecycle

service has 0 endpoints, to allow balancing to a different DC/cluster
with `externalTrafficPolicy=Cluster`

- 🛣️ **Border Gateway Protocol (BGP)**
- 🔌 **Advertise Addresses from Interfaces**: There's a new Interface BGP
advertisement type that allows advertisement of IPs assigned on local
interfaces. This can be useful for example in multi-homing setups, where
a common node's loopback address can be advertised via multiple BGP
sessions over different network interfaces.
