levaliciousandClaude Opus 5.5 8018ea4bf9 lb: keep the client's address past weave's masquerade
images / images (push) Successful in 19m13s
Weave's expose rule (nat WEAVE: ! -s <alloc> -d <alloc> -j MASQUERADE)
masquerades everything entering the pod network from outside unless it is
for a local pod (weaver-no-masq-local). Live on the SG cluster a pod on
another node than the holder saw the holder's bridge address instead of
the client's. A new chain, REWEAVE-LB-POST, hooked first in nat
POSTROUTING, lets a connection we DNATed to a held address leave the nat
table with its source untouched; one that comes from a pod (hairpin) is
masqueraded to the holder instead, so its reply returns through the
holder's conntrack.

levaliciousandClaude Opus 5.5 ef50dc921f lb: DNAT rules carry their protocol; end-to-end test against a cluster
images / images (push) Successful in 14m35s
iptables refuses a DNAT to ip:port unless the same rule names the
protocol, so every per-port chain's DNAT now has -p. Live on the SG
cluster the first sync (no endpoints yet) applied; every later one failed
with "Need TCP, UDP, SCTP or DCCP with port specification" and left the
chains empty. The unit test now rejects any DNAT line without its
protocol; the rendered nat and mangle payloads were also checked with the
nodes' own iptables-restore --test (nf_tables).

reweave/test/lb/run.sh is the end-to-end test: from outside, both a pod on
the holder and one on another node see the client's own address; status
is [{ip, ipMode: Proxy}] and kube-proxy has nothing for the address; a pod
on a third node reaches it; an unheld address clears the status and stops
the forward; deleting the Services removes the holder's chains.

levaliciousandClaude Opus 5.5 9bc3415111 lb: LoadBalancer Services from addresses nodes hold, client address kept
images / images (push) Successful in 14m46s
A Service of type LoadBalancer with loadBalancerClass
reweave.levk.dev/node-address names its address in spec.loadBalancerIP.
Each node's weave-npc publishes the IPv4 addresses on its host interfaces
and its weave bridge (Node annotations reweave.levk.dev/addresses and
reweave.levk.dev/weave). The one node that holds a Service's address is
its holder: it alone writes status.loadBalancer (ipMode Proxy, so
kube-proxy installs nothing for the address) and DNATs the address's ports
to ready endpoints (EndpointSlices), without SNAT, from nat PREROUTING
ahead of kube-proxy. Every other node marks the connections the holder
forwards to its pods (new, from the holder's bridge MAC, from outside the
pod network) and routes their replies back to the holder's bridge through
a per-holder policy rule and table, so the holder's conntrack undoes the
DNAT and the reply leaves from the address the client connected to.

Fail closed: an address no node holds, or that several nodes hold, is
served by no node, and its status is cleared (by its holder, or by the
first node by name if none holds it). Compute is the policy as a pure
function; Datapath replaces exactly the chains it owns with
iptables-restore --noflush and keeps its rules and tables exact.

weave-npc runs it unless --lb=false; the ClusterRole gains services
(watch), services/status (patch), endpointslices (watch), nodes (patch).

reweave/build's `make all` also builds tools/runner from the tools
submodule (weaveworks/build-tools); run 7 compiled every weave binary and
then stopped there. Fetched from upstream for now, like the build's other

Debian has archived both: buster is gone from deb.debian.org and
bullseye's security pool there now 404s on packages its index still
lists (run 6: xz-utils, dpkg-dev, libdpkg-perl). archive.debian.org
serves both releases, including libpcap 1.8.1-6+deb10u1 for the static

levaliciousandClaude Opus 5.5 6260533b6d ci: build weave-kube and weave-npc, push to this Gitea's registry
images / images (push) Failing after 17s
A Gitea Actions workflow that builds the two images the cluster runs from
reweave/build/Dockerfile (linux/amd64 only) and pushes them to
git.levk.dev/reweave/{weave-kube,weave-npc}, tagged with the full commit
SHA so a tag never changes meaning. It stops at the push; rollout is the
CD side's job. Build-time fetches (base images, apt/apk, Go modules) stay
external for now and are to be peeled out once self-deploy works.

## Release 2.9.0
This release has upgraded dependencies based on CVE recommendations.
Also, from this release onwards, all weave images will use the `iptables-nft` backend for `iptables` by default. To use the legacy mode, set the environment variable `IPTABLES_BACKEND` to `legacy`. To do this for the Docker plugin, export the variable before using the `weave` script. For the Kubernetes addon, set the variable in the manifest.
## Release 2.8.10
This release bumps the Go version to 1.23.1 and the alpine base image to version 3.20.3 as per CVE recommendations.
## Release 2.8.9
This release bumps the Go version to 1.22.2, the alpine base image to version 3.20.2, and upgrades a dependency as per CVE recommendations.
## Release 2.8.8
The alpine base image used by `weave-kube` and `weave-npc` has been upgraded to version 3.20.0 in this release. This removes several CVEs.
## Release 2.8.7
This release has upgraded dependencies based on CVE recommendations.
Also, this release does not provides images for the `ppc64le` and `s390x` architectures, because a crucial upstream dependency (libpcap-0.8, from the debian buster respository) does not provide binaries for those architectures any more.
## Release 2.8.6
From this release onwards, the Docker V2 Plugin will be published for all supported architectures. It will be named using the pattern `rajchaudhuri/net-plugin:<version>-<arch>`. The latest version will also be published as `rajchaudhuri/net-plugin:latest_release-<arch>`. Supported architectures are `amd64`,`arm`,`arm64`,`ppc64le` and `s390x`. It can be installed on a Swarm-mode-enabled Docker host as follows:
```bash
ARCH=$(docker version -f '{{.Server.Arch}}')
docker plugin install rajchaudhuri/net-plugin:latest_release-$ARCH
```
## Release 2.8.5
This release has upgraded dependencies based on CVE recommendations.
* Build with Go version 1.21.9
* A dependency has been updated
## Release 2.8.4
The alpine base image used by `weave-kube` and `weave-npc` was upgraded to version 3.19.1 in the previous release. In this version, the default iptables backend is nftables, and the legacy backend is not included. Our scripts and programs assume legacy as the default backend, and change to nft if autodetected, or if we ask for it. So, the build Dockerfile (reweave/build/Dockerfile) was changed to also install the Alpine `iptables-legacy` package , and change the `iptables-{save,restore}` symbolic links to point to the legacy backend by default.
The `weave-kube` and `weave-npc` images can now log traces if the environment WEAVE_DEBUG is set in the manifest.
## Release 2.8.3
The docker API client version, used by the proxy package and the weaveutil command, was bumped from 1.18 to 1.24. As of March 2024, Docker API versions below 1.24 are deprecated. This means that the minimum supported Docker version is now 1.12.0.
Provision was made in weaveutil program and the weave script to override the API version used, via the environment variable `DOCKER_API_VERSION`. The same variable is used by standard docker clients.
## Release 2.8.2
This is the first release since forking from weaveworks/weave. While no new functionality has been added, there have been many changes.

## Using Weave on Kubernetes
## Using Weave Net on Kubernetes
On a newly created Kubernetes cluster, the Weave Net CNI pluging can be installed by running the following command:
```
kubectl apply -f https://reweave.azurewebsites.net/k8s/v1.28/net.yaml
kubectl apply -f https://reweave.azurewebsites.net/k8s/v1.29/net.yaml
```
Replace `v1.28` with the version on Kubernetes on your cluster.
Replace `v1.29` with the version on Kubernetes on your cluster.
That endpoint is provided by the companion project [weave-endpoint](https://github.com/rajch/weave-endpoint).
## Building Weave
## Using Weave Net in other ways
Please refer to the [documentation](https://rajch.github.io/weave).
## Building Weave Net
Details can be found [here](reweave/BUILDING.md).
## Documentation status
At this point, any information found in directories other than `reweave`, such as `docs` or `site`, should be considered obsolete. In time, those will be updated.
The public documentation that used to exist in the `site` directory has been moved to the `original/site` directory. A new `website` directory has been created, and populated with the content of the `original/site` directory, rearranged and reformatted for being built with Jekyll and published to the GitHub pages site [https://rajch.github.io/weave](https://rajch.github.io/weave).
The documentation will now be maintained and published from the `website` directory exclusively.

// A Service opts in with spec.loadBalancerClass = Class and names its
// address in spec.loadBalancerIP. The node that holds the address (has it on
// one of its interfaces, as published in its AnnAddresses annotation) is the
// address's holder: it alone writes the Service's status (ipMode Proxy, so
// kube-proxy installs no rules for the address) and DNATs the address's
// ports to ready endpoints, without SNAT. Every other node marks the
// connections that the holder forwards to its pods, and routes their replies
// back to the holder over weave, so that the holder's conntrack can undo the
// DNAT and the reply leaves from the address the client connected to.
