The address attribute interface was intended to provide a mechanism to
pass attributes separately from channel args, for values that do not
affect subchannel behavior and therefore do not need to be present in
the subchannel key, which does include channel args. However, the
mechanism as currently designed is fairly clunky and is probably not the
direction we will want to go in the long term.
Eventually, we will want some mechanism for registering channel args,
which would provide a cleaner way to indicate that a given channel arg
should not be used in the subchannel key, so that we don't need a
completely different mechanism. For now, this PR is just doing an
interim step, which is to establish a special channel arg key prefix to
indicate that an arg is not needed in the subchannel key.
This change simplifies `EventEngine::DNSResolver`'s API based on the
proposal:
[go/event-engine-dns-resolver-api-changes](http://go/event-engine-dns-resolver-api-changes).
Note that this API change + the implementation described in
[go/event-engine-dns-resolver-implementation](http://go/event-engine-dns-resolver-implementation)
has already been tested against our main test suites and are passing
them.

The approach of doing a recursive function call to expand the if checks
for known metadata names was tripping up an optimization clang has to
collapse that if/then tree into an optimized tree search over the set of
known strings. By unrolling that loop (with a code generator) we start
to present a pattern that clang *can* recognize, and hopefully get some
more stable and faster code generation as a benefit.

This is another attempt to add support for vsock in grpc since previous
PRs(#24551, #21745) all closed without merging.
The VSOCK address family facilitates communication between
virtual machines and the host they are running on.
This patch will introduce new scheme: [vsock:cid:port] to
support VSOCK address family.
Fixes#32738.

This reverts the changes made to ring_hash in #29872. The comment in the
picker code specifically says not to change these variables to an
unsigned type, but that's exactly what that PR did. I don't know if this
has actually been causing any problems, but given that we duplicated
this algorithm (and that comment) from elsewhere without doing a
detailed analysis of it, it seems prudent to stick with the types that
the original code suggested were important.
To avoid causing problems for ObjC, I have changed this such that
ring_hash is not built unless we are building with xDS support, which we
exclude on mobile. Currently, there is no way to use ring_hash without
xDS, although that might change in the future; if it does, we can deal
with any problems that arise at that point.
`tools/run_tests/sanity/check_absl_mutex.sh` was broken, a missing paren
crashed the script if run locally. It's unclear yet how our sanity
checks were not complaining about this, `run_tests.py` does not save the
log.
This check compares the host portion of the target name to the authority
header, but in common use cases (e.g. GCS) they may not coincide.
Additionally, this check does not happen in the Go and Java ALTS stacks.
This makes the JSON API visible as part of the C-core API, but in the
`experimental` namespace. It will be used as part of various
experimental APIs that we will be introducing in the near future, such
as the audit logging API.
Reverts grpc/grpc#32924. This breaks the build again, unfortunately.
From `test/core/event_engine/cf:cf_engine_test`:
```
error: module .../grpc/test/core/event_engine/cf:cf_engine_test does not depend on a module exporting 'grpc/support/port_platform.h'
```
@sampajano I recommend looking into CI tests to catch iOS problems
before merging. We can enable EventEngine experiments in the CI
generally once this PR lands, but this broken test is not one of those
experiments. A normal build should have caught this.

Reverts grpc/grpc#33002. Breaks internal builds:
`.../privacy_context:filters does not depend on a module exporting
'.../src/core/lib/channel/context.h'`
Change call attributes to be stored in a `ChunkedVector` instead of
`std::map<>`, so that the storage can be allocated on the arena. This
means that we're now doing a linear search instead of a map lookup, but
the total number of attributes is expected to be low enough that that
should be okay.
Also, we now hide the actual data structure inside of the
`ServiceConfigCallData` object, which required some changes to the
`ConfigSelector` API. Previously, the `ConfigSelector` would return a
`CallConfig` struct, and the client channel would then use the data in
that struct to populate the `ServiceConfigCallData`. This PR changes
that such that the client channel creates the `ServiceConfigCallData`
before invoking the `ConfigSelector`, and it passes the
`ServiceConfigCallData` into the `ConfigSelector` so that the
`ConfigSelector` can populate it directly.
Makes some awkward fixes to compression filter, call, connected channel
to hold the semantics we have upheld now in tests.
Once the fixes described here
https://github.com/grpc/grpc/blob/master/src/core/lib/channel/connected_channel.cc#L636
are in this gets a lot less ad-hoc, but that's likely going to be
post-landing promises client & server side.
We specifically need special handling for server side cancellation in
response to reads wrt the inproc transport - which doesn't track
cancellation thoroughly enough itself.

Whilst the per cpu counters probably help single channel contention, we
think it's likely that they're a pessimization when taken fleetwide.

Add audit condition and audit logger config into `grpc_core::Rbac`.
Support translation of audit logging options from authz policy to it.
Audit logging options in authz policy looks like:
```json
{
"audit_logging_options": {
"audit_condition": "ON_DENY",
"audit_loggers": [
{
"name": "logger",
"config": {},
"is_optional": false
}
]
}
}
```
which is consistent with what's in the xDS RBAC proto but a little
flattened.

This paves the way for making pick_first the universal leaf policy (see
#32692), which will be needed for the dualstack design. That change will
require changing pick_first to see both the raw connectivity state and
the health-checking connectivity state of a subchannel, so that we can
enable health checking when pick_first is used underneath round_robin
without actually changing the pick_first connectivity logic (currently,
pick_first always disables health checking). To make it possible to do
that, this PR moves the health checking code out of the subchannel and
into a separate API using the same data-watcher mechanism that was added
for ORCA OOB calls.
The PR also creates a separate BUILD target for:
- chttp2 context list
- iomgr buffer_list
- iomgr internal errqueue
This would allow the context list to be included as standalone
dependencies for EventEngine implementations.
As Protobuf is going to support Cord to reduce memory copy when
[de]serializing Cord fields, gRPC is going to leverage it. This
implementation is based on the internal one but it's slightly modified
to use the public APIs of Cord. only

The very non-trivial upgrade of third_party/protobuf to 22.x
This PR strives to be as small as possible and many changes that were
compatible with protobuf 21.x and didn't have to be merged atomically
with the upgrade were already merged.
Due to the complexity of the upgrade, this PR wasn't created
automatically by a tool, but manually. Subsequent upgraded of
third_party/protobuf with our OSS release script should work again once
this change is merged.
This is best reviewed commit-by-commit, I tried to group changes in
logical areas.
Notable changes:
- the upgrade of third_party/protobuf submodule, the bazel protobuf
dependency itself
- upgrade of UPB dependency to 22.x (in the past, we used to always
upgrade upb to "main", but upb now has release branch as well). UPB
needs to be upgraded atomically with protobuf since there's a de-facto
circular dependency (new protobuf depends on new upb, which depends on
new protobuf for codegen).
- some protobuf and upb bazel rules are now aliases, so `
extract_metadata_from_bazel_xml.py` and `gen_upb_api_from_bazel_xml.py`
had to be modified to be able to follow aliases and reach the actual
aliased targets.
- some protobuf public headers were renamed, so especially
`src/compiler` needed to be updated to use the new headers.
- protobuf and upb now both depend on utf8_range project, so since we
bundle upb with grpc in some languages, we now have to bundle utf8_range
as well (hence changes in build for python, PHP, objC, cmake etc).
- protoc now depends on absl and utf8_range (previously protobuf had
absl dependency, but not for the codegen part), so python's
make_grpcio_tools.py required partial rewrite to be able to handle those
dependencies in the grpcio_tools build.
- many updates and fixes required for C++ distribtests (currently they
all pass, but we'll probably need to follow up, make protobuf's and
grpc's handling of dependencies more aligned and revisit the
distribtests)
- bunch of other changes mostly due to overhaul of protobuf's and upb's
internal build layout.
TODOs:
- [DONE] make sure IWYU and clang_tidy_code pass
- create a list of followups (e.g. work to reenable the few tests I had
to disable and to remove workaround I had to use)
- [DONE in cl/523706129] figure out problem(s) with internal import

I added the `CallDispatchController` interface back in #26200 in
preparation for supporting the retry circuit breaker in xDS. However, we
subsequently decided not to support that feature, so we no longer need
this interface. And switching back to a simple on-commit callback should
make it easier to implement stateful session affinity for
WeightedClusters.
When using this internally, we noticed that it's impossible to use
custom_metadata.h without creating a dependency cycle between
:custom_metadata and :grpc_base.
A full build refactoring is too large right now, so merge that header
into :grpc_base for the time being.
Also, separate `SimpleSliceBasedMetadata` into its own file, so that it
can be reused in custom_metadata.h.

This PR also centralizes the client channel resolver selection. Resolver
selection is still done using the plugin system, but when the Ares and
native client channel resolvers go away, we can consider bootstrapping
this differently.
