WebAssembly Micro Runtime (WAMR) is a standalone WebAssembly (WASM) runtime with a small footprint. It includes a few parts as below:
The "iwasm" VM core, supporting WebAssembly interpreter, ahead of time compilation (AoT) and Just-in-Time compilation (JIT)
The application framework and the supporting API's for the WASM applications
The dynamic management of the WASM applications
Risk Level: Medium
Testing: Runtime unit testing, integration testing and manual testing

It is to fix: https://github.com/envoyproxy/envoy/issues/14556#issuecomment-754203164
Currently, remote Jwks is fetched on-demand, in the worker thread after the requests come. The first few requests need to pause to wait for the Jwks.
Add a new feature to fetch remote Jwks in the main thread, before the listener is activated.
Detail changes:
* Change the filter config to add async_fetch field inside RemoteJwks message
* Add a new class: JwksAsyncFetcher class to handle this new config.
* Add two new statistics counters `jwks_fetch_success` and `jwks_fetch_fail`.
Risk Level: Low since new feature is guarded by the new config.
Testing: unit-tested and integration tested

This is a PR for scoping token buckets in the local rate limiting flow on a per connection basis as opposed to scoping it on the entire envoy instance. More details in #15637
Currently, the HTTP local rate limiter's token bucket is shared across all workers, thus causing the rate limits to be applied per Envoy instance/process. This could potentially result in bad actors quickly exhausting limits on a given envoy instance before legitimate users have had a fair chance. We achieve this by adding an instance of the LocalRateLimit::LocalRateLimiterImpl to each connection object, if there isn't one already, via FilterState data
Risk Level: Low
Testing:
Added unit tests to local_ratelimit
Manually tested via curl'ing against a locally patched envoy instance.
One can send multiple requests on the same connection via curl using the following:
curl -vI example.com example.com
Docs Changes:
Added new toggle to local rate limit configuration to enable per connection local rate limiting
// Specifies the scope of the rate limiter's token bucket.
// If set to false, the token bucket is shared across all worker threads
// thus the rate limits are applied per Envoy process.
// If set to true, a token bucket is allocated for each connection.
// Thus the rate limits are applied per connection thereby allowing
// one to rate limit requests on a per connection basis.
// If unspecified, the default value is false.

Commit Message: To prevent long event loop when too many UDP packets are in the queue, limit how many packets to read in each event loop. If haven't finished reading, artifacts a READ event to continue in the next event loop.
Additional Description:
Add numPacketsExpectedPerEventLoop() callback to UdpListenerCallback, so that QUIC listener can tell how many packets it wants to read in each loop. The actually number of packets read are still bound by MAX_NUM_PACKETS_PER_EVENT_LOOP (6000).
Quic listener returns numPacketsExpectedPerEventLoop() based on number of connections it has at the moment and the configured envoy::config::listener::QuicProtocolOptions.packets_to_read_to_connection_count_ratio.
Made InjectableSingleton really thread safe.
Risk Level: medium, other than quic listener, other UdpListenerCallbacks return max size_t for numPacketsExpectedPerEventLoop(). This will cause those callbacks to read 6000 packets per READ event.
Testing: added udp listener unit tests.

This is a follow-up to:
#14432 (comment)
After that PR, it's no longer possible (unless you do a dynamic_cast)
to set the remote address from a filter. This is something that we
need to do because we have specialized logic for this (XFF doesn't
work for us).
So this adds an extension point which will allow us to push that logic
down to ConnectionManagerUtility::mutateRequestHeaders() where it
belongs.

canonical must include the hashed payload for most services. The prior
behavior of using UNSIGNED-PAYLOAD is an exception to the rule, which
select services like s3 support, since hashing the payload may be
impractical if the payload is very large.
A new filter option is introduced, so that the filter may be explicitly
configured to use the UNSIGNED-PAYLOAD string literal as specified
in the S3 signing docs:
https://docs.aws.amazon.com/general/latest/gr/sigv4-create-canonical-request.htmlfixes#13904
Additional Description:
The original implementation was seemingly very specific to S3 and was subsequently amended to extend the same niche singing behaviors for ES and Glacier. This changes the filter's default behavior to match the general SigV4 guidelines while providing a configuration option to enable the specialized UNSIGNED-PAYLOAD behavior.
https://docs.aws.amazon.com/general/latest/gr/sigv4-create-canonical-request.html
Risk Level: Medium?
Deployments using the filter will now buffer requests by default, which could result in 413 responses for requests with bodies exceeding the buffer limit. These users can mitigate buffering by enabling the `unsigned_payload` option.
Testing:
I tested locally with a filter config. I anticipate updating the automated tests based on feedback from maintainers.

Docs Changes: Marked "clear_route_cache" in the API as no longer

Release Notes: If the clear_route_cache flag is set on a
response from the external processing server, then the filter will
call the "clearRouteCache" method on the filter state. Processors
should set this flag if they have changed any headers, such as
":path", which may affect routing after the filter runs.

If listener1 redirects the connection to listener2, the balancer field in listener2 decides whether to rebalance.
Previously we rely on the rebalancing at listener1, however, the rebalance is weak because listener1 is likely to
not own any connection and the rebalance is no-op.
Risk Level: MID. Rebalance may introduce latency. User needs to clear rebalancer field of listener2 to recover the original behavior.

Existing trailers will be sent to the processing
server if the processing mode is set to enable them. If the
processing mode is set to sent trailers, but there are no trailers
present, then empty trailers will be sent to the server for
modification.
However, trailers may only be added in the end of the data callback
in Envoy, which may come in before a previous gRPC reply returns.
Filters that need to be able to consistently add trailers where none
existed should enable trailer processing in the Envoy filter
configuration instead of relying on being able to turn it on
dynamically.
Risk Level: Low. Trailers only enabled if a service called by the filter
is configured to ask for them.
Testing: New integration and unit tests added.
Docs Changes: API docs updated in .proto files.
Release Notes:
When the processing mode is changed to SEND
for request or response trailers, a corresponding message will be
sent to the server, which can respond with trailer mutations as desired.
In addition, if trailer processing is enabled in the filter
configuration, then trailer messages will be sent to the server
even if trailers are not present. This makes it possible for the server
to add trailers where none exist.
Finally, at the moment Envoy only implements trailers for the HTTP/2
protocol. Nothing will happen if trailer processing is enabled and
Envoy is using HTTP/1 until Envoy implements trailers for HTTP/1.

Fixes a few issues with the generated Go protobuf code:
a) the OT protos are not copied over, which means that their importpath
needs to reference a path where it can pull the protos down from. The
"logs" importpath was nonsensical and couldn't be resolved
b) Bunching several proto packages into one target did not work well

own target so that it can reference a different importpath than the
