Merged
Conversation
This branch adds a new test for failure accrual in load balancers with multiple endpoints. This test asserts that endpoints whose circuit breakers have tripped will not be selected by a load balancer.

Looks like we accidentally merged PR #2375 without a CI build against the latest state of `main`. In the meantime since #2375 was last built on CI, PR #2374 added an additional metadata field to `policy::HttpParams`, which the `HttpParams` constructed in the test added from #2375 doesn't populate. Therefore, merging this PR broke the build. Whoops! This commit populates the `meta` field, fixing it.

This proxy release fixes an issue where outbound proxies would attempt protocol detection on ports that are marked as opaque. It also adds support for ranges (such as `10-20`) in the `LINKERD2_PROXY_INBOUND_PORTS_DISABLE_PROTOCOL_DETECTION` and `LINKERD2_PROXY_INBOUND_PORTS` environment variables. Finally, it changes the proxy to synthesize default client policies when the policy controller returns an `Unimplemented` gRPC status code, allowing 2.13 proxies to coexist with 2.12 control planes in downgrade scenarios. --- * outbound: determine protocol based on `OutboundPolicy` (linkerd/linkerd2-proxy#2397) * set default `trust_dns` log level to `ERROR` (linkerd/linkerd2-proxy#2393) * outbound: test load balancer behavior with failure accrual (linkerd/linkerd2-proxy#2375) * outbound: add missing `meta` field in test policy (linkerd/linkerd2-proxy#2400) * inbound: determine default policies using the opaque ports env var (linkerd/linkerd2-proxy#2395) * outbound: synthesize client policies on `Unimplemented` (linkerd/linkerd2-proxy#2396) * build(deps): bump io-lifetimes from 1.0.4 to 1.0.10 (linkerd/linkerd2-proxy#2379) * chore: allow `syn` v1 and v2 to coexist peacefully (linkerd/linkerd2-proxy#2401) * build(deps): bump futures from 0.3.26 to 0.3.28 (linkerd/linkerd2-proxy#2370) * build(deps): bump async-trait from 0.1.66 to 0.1.68 (linkerd/linkerd2-proxy#2368) Signed-off-by: Eliza Weisman <eliza@buoyant.io>
