Robert Klotzner c0347f026a Jaeger spans for availability distribution (#2559)
* Logging functionality for spans.

* Jaeger spans for availability distribution.

* Fix instrumentation to use log target properly.

* Add some tracing instrumentation macros.

* Use int_tags instead of logs.

* Add span per iteration.

* Remove span::log functionality.

* Fix instrumentation log target for real.

* Add jaeger span to responding side as well.

* Revert "Fix instrumentation log target for real."

This reverts commit e1c2a2e6ff6f257e702f07d8a77c2668af92b0ef.

* Revert "Fix instrumentation to use log target properly."

This reverts commit 7caa0bd1acc6fe9727bb3a91851560d756c40ab8.

* target -> subsystem in instrumentatio macro

target is not correct either, and the correct way of using a top level
target = LOG_TARGET does not work, as the macro expects a string literal
and gets confused by the constant `LOG_TARGET`.

* Use kebab-case for spa names.

Robert Klotzner 78ac4b7add Whole subsystem test for new availability-distribution (#2552)
* WIP: Whole subsystem test.

* New tests compile.

* Avoid needless runtime queries for no validator nodes.

* Make tx and rx publicly accessible in virtual overseer.

This simplifies mocking in some cases, as tx can be cloned, but rx can
not.

* Whole subsystem test working.

* WIP

* availability distribution, still very wip.

Work on the requesting side of things.

Bastian Köcher 4975521d48 Notify collators about seconded collation (#2430)
* Notify collators about seconded collation

This pr adds functionality to inform a collator that its collation was
seconded by a parachain validator. Before this signed statement was only
gossiped over the validation substream. Now, we explicitly send the
seconded statement to the collator after it was validated successfully.

Besides that it changes the `CollatorFn` to return an optional result
sender that is informed when the build collation was seconded by a
parachain validator.

* Add test

* Make sure we only send `Seconded` statements

* Make sure we only receive valid statements

Robert Klotzner 0cb1ccd122 Generic request/response infrastructure for Polkadot (#2352)
* Move NetworkBridgeEvent to subsystem::messages.

It is not protocol related at all, it is in fact only part of the
subsystem communication as it gets wrapped into messages of each
subsystem.

* Request/response infrastructure is taking shape.

WIP: Does not compile.

* Multiplexer variant not supported by Rusts type system.

* request_response::request type checks.

* Cleanup.

* Minor fixes for request_response.

* Implement request sending + move multiplexer.

Request multiplexer is moved to bridge, as there the implementation is
more straight forward as we can specialize on `AllMessages` for the
multiplexing target.

Sending of requests is mostly complete, apart from a few `From`
instances. Receiving is also almost done, initializtion needs to be
fixed and the multiplexer needs to be invoked.

* Remove obsolete multiplexer.

* Initialize bridge with multiplexer.

* Finish generic request sending/receiving.

Subsystems are now able to receive and send requests and responses via
the overseer.

* Doc update.

* Fixes.

* Link issue for not yet implemented code.

* Fixes suggested by @ordian - thanks!

- start encoding at 0
- don't crash on zero protocols
- don't panic on not yet implemented request handling

* Update node/network/protocol/src/request_response/v1.rs

Use index 0 instead of 1.

Sergei Shulepov d4fdbf7db9 Clean up PersistedValidationData (#2353)
* PVD: `block_number`->`relay_parent_number`

* ValidationParams: `relay_chain_height`->`relay_parent_number`

* Expose DMQ MQC hash as a well-known-key

This way the relay storage merkle proofs will be able to obtain the DMQ
MQC hash and we will be able to remove the it from the
PersistedValidationData struct.

* PersistedValidationData: Remove HRMP MQC heads

* PersistedValidationData: Remove `dmq_mqc_head`

* Expose the HRMP ingress channel index as a well-known-key

This way a parachain (PVF and collator) can find all the parachains that
have an outbound channel to the given one. That allows in turn to find
all the inbound channels for the given para.

Having access to that allows the parachain to get the same information
as the hrmp_mqc_heads now provide.

* Rename `relay_storage_root` to `relay_parent_storage_root`

Bastian Köcher 1439558f14 Compress the PoV block before sending it over the network (#2288)
* Compress the PoV block before sending it over the network

This pr changes the way we send PoV blocks over the network. We now
compress the PoV block before it is send over the network. This should
reduce the size significant for PoVs which contain the runtime WASM for
example.

* Preallocate 1KB

* Try something..

* Switch to zstd and some renamings

* Make compression/decompression fail in browsers

* Use some sane maximum value

* Update roadmap/implementers-guide/src/types/network.md

Robert Klotzner 32d4670b0d Some refactoring in network-bridge in the course of dealing with #2177 (#2263)
* More doc fixes.

* Minor refactorings in the process of #2177

By having everything peer set related depend directly on the enum the
code becomes more clear and it is also straight forward to add more
peersets/protocols as the compiler will complain if you forget to
implement parts of it.

* Add peer set infos on startup properly

For feature real_overseer.

+ Fixes from review. Thanks @coriolinus and @ordian!

* More structure in network-bridge

Some changes, which would have helped me in groking the code faster.

Entry points/public types more to the top. Factored out implementation
in their own files, to clear up the top-level view.

* Get rid of local ProtocolName type definition.

Does not add much at this level.

* Fix tests + import cleanup.

* Make spaces tabs.

* Clarify what correct parameters to send_message are

* Be more less vague in docs of send_message.

* Apply suggestions from code review

Extend copyright on new files to 2021 as well.

Bastian Köcher 475915ff10 Do not send empty view updates to peers (#2233)
* Do not send empty view updates to peers

It happened that we send empty view updates to our peers, because we
only updated our finalized block. This could lead to situations where we
overwhelmed sub systems with too many messages. On Rococo this lead to
constant restarts of our nodes, because some node apparently was
finalizing a lot of blocks.

To prevent this, the pr is doing the following:

1. If a peer sends us an empty view, we report this peer and decrease it
reputation.

2. We ensure that we only send a view update when the `heads` changed
and not only the `finalized_number`.

3. We do not send empty `ActiveLeavesUpdates` from the overseer, as this
makes no sense to send these empty updates. If some subsystem is relying
on the finalized block, it needs to listen for the overseer signal.
