Earlier, the grpc message-length prefix for outgoing data messages was
incorrectly being counted towards `data_bytes` instead of
`framing_bytes`. This PR fixes it.
Note that the incoming stats collection properly attributes the grpc
message-length prefix to `framing_bytes`.
This change will affect all stats plugins (OpenCensus and OpenTelemetry)
that make use of this information for metrics.
Let's not merge this PR this week, maybe 2023-10-23 at the earliest.
This will allow time for flakes to shake out of the listener experiments
(enabled in https://github.com/grpc/grpc/pull/34700) in isolation of
client problems.
Add TcpTracer interface for TCP instrumentation. It takes no gRPC
dependencies for use in external TCP implementations. Also add
HttpAnnotation for HTTP transport instrumentation using CallTracer.

This PR aims to fix the issue found in frame_fuzzer after #34191 was
merged, where frame serialization is missing the frame header info and
causes mismatch with the original frame.
This PR needs to be merged before #34657.

This reverts commit 601aaf80b7, which
results in rolling forward #34408.
The 601aaf reversion happened because of a deadlock found in Python. The
root cause ended up being an issue with the Python wrapper and was fixed
in #34712 , so this can be rolled forward again
Ditch the old priority scheme for ordering filters, instead explicitly
mark up before/after constraints.

The basic APIs for the CRL Reloading features.
This adds external types to represent CRL Providers, CRLs, and
CertificateInfo.
Internally we will use `CrlImpl` - this layer is needed to hide OpenSSL
details from the user.
GRFC - https://github.com/grpc/proposal/pull/382
Things Done
* Add external API for `CrlProvider`, `Crl`, `CertInfo` (`CertInfo` is
used during CRL lookup rather than passing the entire certificate).
* Add code paths in `ssl_transport_security` to utilize CRL providers
* Add `StaticCrlProvider`
* Refactor `crl_ssl_transport_security_test.cc` so it is more extensible
and can be used with providers
@stanley-cheung noticed a bug where CSM labels were not being added on
metrics if the peer was not also CSM Observability enabled.
This PR fixes the behavior to add in the local labels in this case, as
well as add the remote workload type label with the value of unknown.
Instead of fixing a target size for writes, try to adapt it a little to
observed bandwidth.
The initial algorithm tries to get large writes within 100-1000ms
maximum delay - this range probably wants to be tuned, but let's see.
The hope here is that on slow connections we can not back buffer so much
and so when we need to send a ping-ack it's possible without great
delay.
Just seeing data flowing in after a ping is enough to establish liveness
of a connection, and so we can limit keepalive timeouts to that. Ping
timeouts are necessary for protocol correctness, but may be stuck behind
other traffic, so give them a little more of a grace period.

Fix b/304114403
- adds a new experimental tracer useful for diagnosing ping timeout
failures in unit tests
- adds a pair of experimental tracers for fuzzing event engine
- fix the behavior of FuzzingEventEngine so that a RunAfter(0, ...) runs
in the same tick
- up the rate of sends (reduce the send delay) so we guarantee to be
able to send 200kb/sec in fuzzed e2e unit tests

The `TickForDuration()` method was using `grpc_core::Timestamp::Now()`
to get the current time, but that was not in sync with the `now_` value
inside the Fuzzing EE itself, with the result that after two subsequent
250ms increments, timers were not being properly fired. I've added a
test that demonstrates this failure without the fix.
Experiment 1: On RST_STREAM: reduce MAX_CONCURRENT_STREAMS for one round
trip.
Experiment 2: If a settings frame is outstanding with a lower
MAX_CONCURRENT_STREAMS than is configured, and we receive a new incoming
stream that would exceed the new cap, randomly reject it.

Previously chttp2 would allow infinite requests prior to a settings ack
- as the agreed upon limit for requests in that state is infinite.
Instead, after MAX_CONCURRENT_STREAMS requests have been attempted,
start blanket cancelling requests until the settings ack is received.
This can be done efficiently without allocating request state
structures.
This is the initial change of chaotic-good client transport read path,
which is a following PR of the client transport write path at #33876.
There's a pending work of handling endpoint failures in the transport.
It will be added after we have the inter-activity pipe with close
function.
