Use Peer::m_their_services instead
|
|
`Misbehaving` has several coding related issues (ignoring the conceptual
issues here for now):
* It is public, but it is not supposed to be called from outside of
net_processing. Fix that by making it private and creating a public
`UnitTestMisbehaving` method for unit testing only.
* It doesn't do anything if a `nullptr` is passed. It would be less
confusing to just skip the call instead. Fix that by passing `Peer&`
to `Misbehaving()`.
* It calls `GetPeerRef`, causing `!m_peer_mutex` lock annotations to be
propagated. This is harmless, but verbose. Fix it by removing the no
longer needed call to `GetPeerRef` and the no longer needed lock
annotations.

703b1e612a4bd4521e20ae21eb8fb7c19f4ef942 Close minor startup race between main and scheduler threads (Larry Ruane)
Pull request description:
This is a low-priority bug fix. The scheduler thread runs `CheckForStaleTipAndEvictPeers()` every 45 seconds (EXTRA_PEER_CHECK_INTERVAL). If its first run happens before the active chain is set up (`CChain::SetTip()`), `bitcoind` will assert:
```
(...)
2021-07-28T22:16:49Z init message: Loading block index…
bitcoind: validation.cpp:4968: CChainState& ChainstateManager::ActiveChainstate() const: Assertion `m_active_chainstate' failed.
Aborted (core dumped)
```
I ran into this while using the debugger to investigate an unrelated problem. Single-stepping through threads with a debugger can cause the relative thread execution timing to be very different than usual. I don't think any automated tests are needed for this PR. I'll give reproduction steps in the next PR comment.

code review ACK 703b1e612a4bd4521e20ae21eb8fb7c19f4ef942 - it makes sense to me to start peerman's background tasks here, after `chainstate->LoadChainTip()` and `node.connman->Start()` have been called.

Don't schedule class PeerManagerImpl's background tasks from its
constructor, but instead do that from a separate method,
StartScheduledTasks(), that can be called later at the end of startup,
after other things, such as the active chain, are initialzed.

Callers of the external RelayTransactions() no longer need to lock cs_main.

680eb56d828ce358b4e000c140f5b247ff5e6179 [net processing] Don't pass CConnman to RelayTransactions (John Newbery)
a38a4e8f039dfabfd9435f3a63f1a9b56de086d6 [net processing] Move RelayTransaction into PeerManager (John Newbery)
Pull request description:
This is the first part of #21160. It moves the RelayTransaction() function to be a member function of the PeerManager class. This is required in order to move the transaction inventory data into the Peer object, since Peer objects are only accessible from within PeerManager.

Pull request description:
(Picking up #20044. Rebased against master.)
This changes various uses of integers to represent timestamps and durations to `std::chrono` duration types with type-safe conversions, getting rid of various `.count()`, constructors, and conversion factors.

Use the local m_connman instead
|
|
We don't mark RelayTransaction as const. Even though it doesn't mutate
PeerManagerImpl state, it _is_ mutating the internal state of a CNode
object, by updating setInventoryTxToSend. In a subsequent commit, that
field will be moved to the Peer object, which is owned by
PeerMangerImpl.
This requires PeerManagerImpl::ReattemptInitialBroadcast() to no longer
be const.

To make eclipse attacks more difficult, regularly initiate outbound connections
and stay connected long enough to sync headers and potentially learn of new
blocks. If we learn a new block, rotate out an existing block-relay peer in
favor of the new peer.
This augments the existing outbound peer rotation that exists -- currently we
make new full-relay connections when our tip is stale, which we disconnect
after waiting a small time to see if we learn a new block. As block-relay
connections use minimal bandwidth, we can make these connections regularly and
not just when our tip is stale.
Like feeler connections, these connections are not aggressive; whenever our
timer fires (once every 5 minutes on average), we'll try to initiate a new
block-relay connection as described, but if we fail to connect we just wait for
our timer to fire again before repeating with a new peer.
