This stable release fixes issues in the proxy and Destination controller which can result in Linkerd proxies sending traffic to stale endpoints. In addition, it contains a bug fix for profile resolutions for pods bound on host ports and includes patches for security advisory [CVE-2023-44487]/GHSA-qppj-fm5r-hxr3 * Control Plane * Fixed an issue where the Destination controller could stop processing changes in the endpoints of a destination, if a proxy subscribed to that destination stops reading service discovery updates. This issue results in proxies attempting to send traffic for that destination to stale endpoints ([#11483], fixes [#11480], [#11279], [#10590]) * Fixed an issue where the Destination controller would not update pod metadata for profile resolutions for a pod accessed via the host network (e.g. HostPort endpoints) ([#11334]) * Addressed [CVE-2023-44487]/GHSA-qppj-fm5r-hxr3 by upgrading several dependencies (including Go's gRPC and net libraries) * Proxy * Fixed a regression where the proxy rendered `grpc_status` metric labels as a string rather than as the numeric status code ([linkerd2-proxy#2480]; fixes [#11449]) * Fixed a regression introduced in stable-2.13.0 where proxies would not terminate unusred service discovery watches, exerting backpressure on the Destination controller which could cause it to become stuck ([linkerd2-proxy#2484]) [#10590]: #10590 [#11279]: #11279 [#11483]: #11483 [#11480]: #11480 [#11334]: #11334 [#11449]: #11449 [CVE-2023-44487]: GHSA-qppj-fm5r-hxr3 [linkerd2-proxy#2480]: linkerd/linkerd2-proxy#2480 [linkerd2-proxy#2484]: linkerd/linkerd2-proxy#2484 Signed-off-by: Matei David <[email protected]>

There was a problem hiding this comment.
LGTM modulo not bumping the linkerd2-cni chart version 😉

This stable release fixes issues in the proxy and Destination controller which
can result in Linkerd proxies sending traffic to stale endpoints. In addition,
it contains a bug fix for profile resolutions for pods bound on host ports and
includes patches for security advisory CVE-2023-44487/GHSA-qppj-fm5r-hxr3
Control Plane
changes in the endpoints of a destination, if a proxy subscribed to that
destination stops reading service discovery updates. This issue results in
proxies attempting to send traffic for that destination to stale endpoints
(#11491, fixes #11480, #11279, #10590)
metadata for profile resolutions for a pod accessed via the host network
(e.g. HostPort endpoints) (#11334)
dependencies (including Go's gRPC and net libraries)
Proxy
grpc_statusmetric labels asa string rather than as the numeric status code (linkerd2-proxy#2480;
fixes #11449)
terminate unusred service discovery watches, exerting backpressure on the
Destination controller which could cause it to become stuck
(linkerd2-proxy#2484)
