This branch cherry-picks #2472 onto `release/v2.203`. Currently, the proxy [depends on an outdated version of `rustls`][1], v0.20.8. The `rustls` dependency is via our dependency on `tokio-rustls` v0.23.4; we don't have a direct `rustls` dependency, in order to ensure that the version of `rustls` is always the same version as used by `tokio-rustls`. `rustls` also has a dependency on `webpki`, and v0.20.x of `rustls` uses the original `webpki` crate, rather than the `rustls-webpki` crate. So, unfortunately, because we have a transitive dep on `webpki` via `rustls`, PR linkerd/linkerd2-proxy#2465 did not remove _all_ `webpki` deps from our dependency tree, only the direct dependency. This branch updates to `rustls` v0.21.x, which depends on `rustls-webpki` rather than `webpki`, removing the `webpki` dependency. This is accomplished by updating `tokio-rustls` to v0.24.x, implicitly updating the transitive `rustls` dep. In order to update to the semver-incompatible version of `rustls`, it was necessary to modify our code in order to track some breaking API changes. I've also added a `cargo-deny` ban for `webpki` to our `deny.toml`, to ensure that we always use the actively-maintained `rustls-webpki` crate rather than `webpki` classic. Since peer certificate validation is performed through `rustls` rather than through the direct `rustls-webpki` dependency, this should hopefully resolve issues with issuer certs that contain name constraints --- these were not fixed by linkerd/linkerd2-proxy#2465, because the failure with certs containing name constraints occurred inside of the *`webpki` version depended on by `rustls`*, rather than inside of the proxy's direct dep. See [this comment][2] for details. In addition, it was necessary to update `rustls-webpki` to v0.101.6, since v0.101.5 was yanked due to an accidental API breaking change. <details> <summary>Verifying that we no longer depend on `webpki`:</summary> Before: ```console $ cargo tree -p webpki -i webpki v0.22.1 ├── rustls v0.20.8 │ └── tokio-rustls v0.23.4 │ ├── linkerd-app-integration v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/integration) │ └── linkerd-meshtls-rustls v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/meshtls/rustls) │ ├── linkerd-app-inbound v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/inbound) │ │ ├── linkerd-app v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app) │ │ │ ├── linkerd-app-integration v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/integration) │ │ │ └── linkerd2-proxy v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd2-proxy) │ │ ├── linkerd-app-admin v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/admin) │ │ │ └── linkerd-app v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app) (*) │ │ │ [dev-dependencies] │ │ │ └── linkerd-app-integration v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/integration) │ │ └── linkerd-app-gateway v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/gateway) │ │ └── linkerd-app v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app) (*) │ │ [dev-dependencies] │ │ └── linkerd-app-gateway v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/gateway) (*) │ ├── linkerd-app-outbound v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/outbound) │ │ ├── linkerd-app v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app) (*) │ │ └── linkerd-app-gateway v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/gateway) (*) │ │ [dev-dependencies] │ │ └── linkerd-app-gateway v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/gateway) (*) │ └── linkerd-meshtls v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/meshtls) │ ├── linkerd-app-core v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/core) │ │ ├── linkerd-app v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app) (*) │ │ ├── linkerd-app-admin v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/admin) (*) │ │ ├── linkerd-app-gateway v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/gateway) (*) │ │ ├── linkerd-app-inbound v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/inbound) (*) │ │ ├── linkerd-app-integration v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/integration) │ │ ├── linkerd-app-outbound v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/outbound) (*) │ │ └── linkerd-app-test v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/test) │ │ ├── linkerd-app-inbound v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/inbound) (*) │ │ ├── linkerd-app-integration v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/integration) │ │ └── linkerd-app-outbound v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/outbound) (*) │ │ [dev-dependencies] │ │ ├── linkerd-app-gateway v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/gateway) (*) │ │ ├── linkerd-app-inbound v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/inbound) (*) │ │ └── linkerd-app-outbound v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/outbound) (*) │ ├── linkerd-app-inbound v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/inbound) (*) │ ├── linkerd-proxy-tap v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/proxy/tap) │ │ └── linkerd-app-core v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/core) (*) │ └── linkerd2-proxy v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd2-proxy) │ [dev-dependencies] │ ├── linkerd-app-inbound v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/inbound) (*) │ ├── linkerd-app-integration v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/integration) │ └── linkerd-app-outbound v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/outbound) (*) │ [dev-dependencies] │ ├── linkerd-app-inbound v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/inbound) (*) │ └── linkerd-app-outbound v0.1.0 (/home/eliza/Code/linkerd2-proxy/linkerd/app/outbound) (*) └── tokio-rustls v0.23.4 (*) ``` After: ```console $ cargo tree -p webpki -i error: package ID specification `webpki` did not match any packages ``` </details> [1]: https://github.com/linkerd/linkerd2-proxy/blob/8afc72258b8ced868fbd0bde0235955c0adf4ccd/Cargo.lock#L2450-L2460C2 [2]: #9299 (comment) --- 0e843c9f meshtls: update to `rustls` v0.21.7 (linkerd/linkerd2-proxy#2473) Signed-off-by: Eliza Weisman <eliza@buoyant.io>
