The libstdc++ std::regex implementation is not safe in all cases for user provided input. This change deprecates the used of std::regex in all user facing paths and introduces a new safe regex matcher with an explicitly configurable engine, right now limited to Google's re2 regex engine. This is not a drop in replacement for std::regex as all language features are not supported. As such we will go through a deprecation period for the old regex engine.

Not sure if this is a faithful translation of the original o == "*" conditions. LGTM otherwise, but if we can get a pair of eyes on this that knows CORS it would be great.

@dschaller can you PTAL at all of the CORS changes? I think this is correct, but would appreciate you reviewing the changes also. Thank you! cc @htuch

This looks good to me. Spinning up the sandbox just to be 100% sure.
If the matcher is an exact string of * or a regex pattern of * it should match in both cases.

Talked to @dschaller offline and he is having trouble with his test env, but is OK with shipping with just a review. @htuch do you mind approving?

(envoyproxy#8002) This is part of envoyproxy#7980; basically, we want to leverage the recursive pass that already exists for the deprecated check. This PR does not implement the recursive behavior yet for unknown fields though, because there is a ton of churn, so this PR just has the mechanical bits. We switch plumbing of validation visitor into places such as anyConvert() and instead pass this to MessageUtil::validate. There are a bunch of future followups planned in additional PRs: * Combine the recursive pass for unknown/deprecated check in MessageUtil::validate(). * Add mitigation for envoyproxy#5965 by copying to a temporary before recursive expansion. * [Future] consider moving deprecated reporting into a message validation visitor handler.

With some sandboxing technologies the clock does not reference the machine boot time but the sandbox boot time. This invalidates the assumtpion that the first update in the cluster_manager will most likely fall out of the windows and ends up showing a non intuitive behavior difficult to catch.

[Sending protobuf](https://github.com/openzipkin/zipkin-api/blob/0.2.1/zipkin.proto) is considered to be more efficient than JSON, even compared to the v2's JSON (openzipkin/zipkin#2589 (comment)). This is an effort to rework envoyproxy#6798. The approach is by serializing the v1 model to both v2 JSON and protobuf. Risk Level: Low, since the default is still HTTP-JSON v1 based on https://github.com/openzipkin/zipkin-api/blob/0.2.2/zipkin-api.yaml. Testing: Unit testing, manual integration test with real Zipkin collector server.

Fixes envoyproxy#7980 Signed-off-by: Harvey Tuch <[email protected]> * Fuzz reuse (envoyproxy#8119) This PR allows the envoy_cc_fuzz_test rule to be used when pulling in envoy. which can be useful when you're writing filters for envoy, and want to reuse the fuzzing architecture envoy has already built. other rules already allow for this (see envoy_cc_test in this same file for example). Risk Level: Low Testing: Testing the Old Rule Still Works It is possible to test the old rules still work (even without specifying a repository), by simply choosing your favorite fuzz test, and choosing to run bazel test on it. For example: bazel test //test/common/router:header_parser_fuzz_test. Any envoy_cc_fuzz_test rule should do. Testing New Rules Work I've done testing inside my own repository, but if you want to create your own test rule you can probably do the following in envoy-filter-example: Checkout envoy-filter-example, and update the envoy submodule to this pr. Follow the directions in: test/fuzz/README.md to define a envoy_cc_fuzz_test rule. Make sure to add a line for: repository = "@envoy" which is the new argument being added. You should be able to run the fuzz test.

(envoyproxy#8125) This patch establishes a v3alpha baseline API, by doing a simple copy of v2[alpha] dirs and some sed-style heuristic fixups of BUILD dependencies and proto package namespaces. The objective is provide a baseline which we can compare the output from tooling described in envoyproxy#8083 in later PRs, providing smaller visual diffs. The core philosophy of the API migration is that every step will be captured in a script (at least until the last manual steps), api/migration/v3alpha.sh. This script will capture deterministic migration steps, allowing v2[alpha] to continue to be updated until we finalize v3. There is likely to be significant changes, e.g. in addition to the work scoped for v3, we might want to reduce the amount of API churn by referring back to v2 protos where it makes sense.

In some respects, this is a re-implementation of some of https://github.com/lyft/protoc-gen-star in Python.

Envoy now uses RE2 as a safe regex engine instead of std::regex (envoyproxy/envoy#7878). Because PGV already requires patterns to use RE2 syntax, one option is to use RE2 for C++ patterns as well. This implements it, for use in strings, bytes, repeated items, and may key/value pattern validation. Implements #22 WIP: I ran in to difficulty creating the regex because a regex containing a null character would get cut off... for example, the ascii character test used the pattern, ^[\x00-x7f]+$, and consuming this as a string resulted in creating a null-terminated string pattern ^[ instead of the actual pattern. I think this might be a problem across most of the C++ code? That's why there's a terrible string construction in the pattern creation. Signed-off-by: Asra Ali <[email protected]>

The libstdc++ std::regex implementation is not safe in all cases
for user provided input. This change deprecates the used of std::regex
in all user facing paths and introduces a new safe regex matcher with
an explicitly configurable engine, right now limited to Google's re2
regex engine. This is not a drop in replacement for std::regex as all
language features are not supported. As such we will go through a
deprecation period for the old regex engine.
Fixes #7728
Risk Level: Low, new config for new regex engine.
Testing: New and modified tests.
