The `target_addr` label encodes both the IP address and port in a single string. This makes certain grouping operations cumbersome. In order to support more flexible queries, this change adds `target_ip` and `target_port` labels in addition to the existing `target_addr` label. This should have a negligible impact on prometheus, since it doesn't actually increase timeseries cardinality.

This release features some performance improvements: tokio has been updated to pick up tokio-rs/tokio#4055, and link-time optimizations have been enabled in release builds. These changes reduce CPU and memory overhead in benchmarks. Inbound policy enforcement has been updated so that TCP forwarding is interrupted if a policy update revokes a previously-established authorization. New metrics are exposed to reflect how policies are used by the proxy: `inbound_http_authz_{allow,deny}_total` and `inbound_tcp_authz_{allow,deny,terminate}_total`. The proxy's error metrics, `{inbound,outbound}_{http,tcp}_errors_total`, have been updated to include the traffic target. And the `traffic_addr` metric label is augmented by `target_ip` and `target_port` labels to support more flexible prometheus queries. Inbound TCP metrics now only include a `srv_name` label, as it can't be expected for all inbound connections to include authorization labels (hence the new authz metrics). However, all inbound HTTP metrics--except for the HTTP errors metric, which includes only a `srv_name` label--include both `srv_name` and `saz_name` label. Finally, the inbound and outbound proxies now only exports Route-oriented metrics when a ServiceProfile is enabled, preventing redundant metrics from being exported with no differentiating labels. --- * profiles: Avoid creating a default route stack (linkerd/linkerd2-proxy#1223) * build(deps): bump arbitrary from 1.0.1 to 1.0.2 (linkerd/linkerd2-proxy#1224) * build(deps): bump trust-dns-resolver from `f08860c` to `3d0667a` (linkerd/linkerd2-proxy#1225) * build(deps): bump libc from 0.2.100 to 0.2.101 (linkerd/linkerd2-proxy#1226) * Enable link-time optimizations (linkerd/linkerd2-proxy#1227) * build(deps): bump serde_json from 1.0.66 to 1.0.67 (linkerd/linkerd2-proxy#1228) * build(deps): bump flate2 from 1.0.20 to 1.0.21 (linkerd/linkerd2-proxy#1230) * build(deps): bump thiserror from 1.0.26 to 1.0.28 (linkerd/linkerd2-proxy#1231) * build(deps): bump futures from 0.3.16 to 0.3.17 (linkerd/linkerd2-proxy#1232) * build(deps): bump parking_lot from 0.11.1 to 0.11.2 (linkerd/linkerd2-proxy#1234) * build(deps): bump trust-dns-resolver from `3d0667a` to `v0.21.0-alpha.2` (linkerd/linkerd2-proxy#1233) * Rename push_on_response to push_on_service (linkerd/linkerd2-proxy#1235) * build(deps): bump tokio from 1.10.1 to 1.11.0 (linkerd/linkerd2-proxy#1236) * metrics: Add `target_ip` and `target_port` labels (linkerd/linkerd2-proxy#1238) * inbound: Improve policy metrics (linkerd/linkerd2-proxy#1237) * inbound: Include server labels in tap responses (linkerd/linkerd2-proxy#1239) * Revert rustc update for release builds

The

In order to support more flexible queries, this change adds
target_ipand
target_portlabels in addition to the existingtarget_addrlabel. This should have a negligible impact on prometheus, since it
doesn't actually increase timeseries cardinality.
