This cleanup should be moved inside the loop. Remove the explicit dispatching_ = false; inside the loop.

If we did that we'd end up ctor and dtoring the cleanup object every iteration of this loop instead of every call to this function. Thoughts?

I guess construction/destruction of the callback and the indirection through the callback is far from free. I guess this could be something to hope for in a future C++ standard.

It would be good to have a ScopedSetter class that we could use to set the members to the new value and restore the old value when exiting the scope. Something like:

template<class T> class ScopedSetter {
public:
     ScopedSetter(T& item, T new_value) : item_(item), old_value_(item) {
       item_ = new_value
    }
    ~ScopedSetter() { item_ = old_value_; }
private:
  T& item_;
  T old_value_;
};

ScopedSetter<bool> set_dispatching(dispatching_, true);

Consider doing a single string compare with the full contents of the expected dump including spaces and indentation.

Part of the request is because I think that the indentation of "Number of active streams" is incorrect.

Done. I worry that it might be a little brittle, but at least it's just this one test (and not the entire suite of dump tests).

I broke it out into 3 string cmp of the entire buffer to account for addr values changing.

Should we escape "\0" ?

Also, I'm not confident that HasSubstr works properly here because of the \0 in that C string.

UserSpaceFileEventImpl provides 3 functions

setEnabled(events) declared by FileEvent. The events are registered for callback. Each call detects fired events once, and IO handle will notify the new events in the long run.
activate(events). Explicitly activate the events. The above enabling events are not honored.
poll(events). It should only be used by IO handle. Unlike activate, poll honors the setEnabled. Will schedule callback if there is no pending callback.

…14834)

Introduce the new https://github.com/bazelbuild/rules_fuzzing library for fuzz testing support.

The new library provides new functionality (support for testing the fuzz test locally) and simplifies existing fuzzing tasks. This is the first PR in the series. See envoyproxy#14675 for the detailed rollout plan.

Risk Level: Low (new dependencies and major change to the existing envoy_cc_fuzz_test macro, but does not affect Envoy binary)
Testing: The changes consist of either (a) code that should be a drop-in replacement to the existing functionality, or (b) new targets marked as "manual". For (a), the Envoy regression tests should catch deviations from the original behavior. The new functionality in (b) is either tested manually, or through the OSS-Fuzz integration (changes coming in future PR).
Docs Changes: None (this is test-only functionality).
Release Notes: N/A
Platform Specific Features: The fuzz tests run on Linux platforms only.

Clarify that NACKs should be detected via the presence of the error_details field, rather than by looking at nonce and version; the latter approach does not work for APIs other than LDS or CDS, where the client can change the set of resources it is subscribing to independently of the resource type instance version changing on the server. Also clarify semantics of nonce handling.

…y#14778)

This patch adds max_direct_response_body_size_bytes to set the maximum bytes of the direct response body size (in bytes). The config is added as a field in RouteConfiguration.

Reviving envoyproxy#13487 with a slightly different approach (add the config to RouteConfiguration instead of directly per direct response config entry).

Risk Level: Low, since the default behavior is preserved.
Testing: Updated to test the newly introduced config.
Docs Changes: Updated.
Release Notes: Added.
Fixes envoyproxy#13422

ListenSocketFactoryImpl stores a const std::string& to the first Listener, which is destructed upon LDS update. When reuse_port is enabled, ListenSocketFactoryImpl reads the stale reference which may be a huge garbage string depending on where std::string::size() is aligned to the garbage memory region.

Also add support adding additional headers to the proxy requests to coordinate with the upstream.

This is due to the race described by envoyproxy#22855. Making sure the dispatcher thread is running before starting the test avoids this problem.

This test sends a large number of metadata frames in order to trigger a disconnect. However, it was possible for the disconnect to happen and the connection to be torn down before all the metadata frames had been sent. If that happened, ASAN detected a UAF:

To fix that, write all metadata frames at once.

When building the jni dylib for android, we previously stripped all
debug info to decrease the artifact size. With this change we now
produce the same stripped binary as before, but before stripping it we
create a dump of the debug info suitable for crash reporting.

This is made overly difficult for a few reasons:

1. Bazel doesn't support fission for Android bazelbuild/bazel#14765
2. Extra outputs from rules are not propagated up the dependency tree,
   so just building `android_dist` at the top level, isn't enough to get
   the extra outputs built as well
3. Building the library manually alongside the android artifact on the
   command line results in 2 separate builds, one for android as a
   transitive dependency of `android_dist` and one for the host
   platform

This change avoids #1 fission for now, but the same approach could be used
once that change makes its way to a bazel release.

This change fixes #2 by using a separate output group that can be depended
on by the genrule that writes to dist while avoiding #3 because the custom
rule producing these uses the android transition.

…yproxy#35410)

When the ``AsyncTcpClient`` is being destroyed but it
also has an active client connection, there's a crash since during the
instance destruction, the ``ClientConnection`` object would also be
destroyed, causing ``raiseEvent`` to be called back to
``AsyncTcpClient`` while it is being destroyed

Caught with the following stack trace:

When trying to build and run fuzzers that may throw an exception (e.g.,
`bazel build //test/common/http:path_utility_fuzz_test
--config=asan-fuzzer`) the following error occurs:

NOTE: libFuzzer has rudimentary signal handlers.
      Combine libFuzzer with AddressSanitizer or similar for better crash reports.
SUMMARY: libFuzzer: deadly signal
```

This PR adds a linking flag to allow the fuzzers to properly handle
exceptions.

## Description

Today, when a filesystem watch callback returns a non-OK status or
throws an exception, the error gets propagated to `FileEventImpl` which
uses `THROW_IF_NOT_OK`.

Since there's no exception handler in the `libevent` loop, this causes
`std::terminate` to be called, which crashes Envoy.

**Stack Trace:**

In this change, we are making the `inotify` and `kqueue` watchers handle
callback errors gracefully by catching any exceptions using
`TRY_ASSERT_MAIN_THREAD`, logging errors instead of propagating them and
always returning the `OkStatus` to the event loop.
