af3b0dfc5463c42fb9bff39f020fc1728ed44bc7 net: fix output of peer address in version message (Vasil Dimov)
Pull request description:
If `-logips -debug=net` is specified then we print the contents of the
version message we send to the peer, including his address. Because the
addresses in the version message use pre-BIP155 encoding they cannot
represent a Tor v3 address and we would actually send 16 `0`s instead (a
dummy IPv6 address). However we would print the full address in the log
message. Before this fix:
```
2020-10-21T12:24:17Z send version message: version 70016, blocks=653500, us=[::]:0, them=xwjtp3mj427zdp4tljiiivg2l5ijfvmt5lcsfaygtpp6cw254kykvpyd.onion:8333, peer=0
```
This is confusing because we pretend to send one thing while we actually
send another. Adjust the printout to reflect what we are sending. After
this fix:
```
2020-10-21T12:26:54Z send version message: version 70016, blocks=653500, us=[::]:0, them=[::]:0, peer=0

daf55531260833d597ee599e2d289ea1be0b1d9c Avoid calling CAddrMan::Connected() on block-relay-only peer addresses (Suhas Daftuar)
Pull request description:
This PR does two things:
* Block-relay-only interaction with addrman.
* Calling `CAddrMan::Connected()` on an address that was a block-relay-only peer causes the time we report in `addr` messages containing that peer to be updated; particularly now that we use anchor connections with a our block-relay-only peers, this risks leaking information about those peers. So, stop this.
* Avoiding calling `CAddrMan::Good()` on block-relay-only peer addresses causes the addrman logic around maintaining the new and tried table to be less good, and in particular makes it so that block-relay-only peer addresses are more likely to be evicted from the addrman (for no good reason I can think of). So, mark those addresses as good when we connect.
* Fix test-before-evict bug. There's a bug where if we get a collision in the tried table with an existing address that is one of our current peers, and the connection is long-lived enough, then `SelectTriedCollisions()` might return that existing peer address to us as a test-before-evict connection candidate. However, our logic for new outbound connections would later prevent us from actually making a connection; the result would be that when we get a collision with a long-lived current peer, that peer's address is likely to get evicted from the tried table. Fix this by checking to see if a test-before-evict candidate is a peer we're currently connected to, and if so, mark it as `Good()`.

Being able to invoke Good() is important for address management (new vs tried
table, tried table eviction via test-before-evict). We mitigate potential
information leaks by not calling Connected() on these peer addresses.
|
|
Connected() updates the time we serve in addr messages, so avoid leaking
block-relay-only peer connections by avoiding these calls.
|
|
Now, we only add a transaction to our recentRejects filter if we didn't
already have it, meaning that it is added at most once, as intended.
|
|
If `-logips -debug=net` is specified then we print the contents of the
version message we send to the peer, including his address. Because the
addresses in the version message use pre-BIP155 encoding they cannot
represent a Tor v3 address and we would actually send 16 `0`s instead (a

Add annotations to guard `vRecvGetData` and `orphan_work_set` and fix up places where they were accessed without a lock. There is no current data race because they happen to be accessed by only one thread, but this might not always be the case.

Pull request description:
This replaces the transaction request logic with an encapsulated class that maintains all the state surrounding it. By keeping it stand alone, it can be easily tested (using included unit tests and fuzz tests).
The major changes are:
* Announcements from outbound (and whitelisted) peers are now always preferred over those from inbound peers. This used to be the case for the first request (by delaying the first request from inbound peers), and a bias afters. The 2s delay for requests from inbound peers still exists, but after that, if viable outbound peers remain for any given transaction, they will always be tried first.
* No more hard cap of 100 in flight transactions per peer, as there is less need for it (memory usage is linear in the number of announcements, but independent from the number in flight, and CPU usage isn't affected by it). Furthermore, if only one peer announces a transaction, and it has over 100 in flight already, we still want to request it from them. The cap is replaced with a rule that announcements from such overloaded peers get an additional 2s delay (possibly combined with the existing 2s delays for inbound connections, and for txid peers when wtxid peers are available).
* The limit of 100000 tracked announcements is reduced to 5000; this was excessive. This can be bypassed using the PF_RELAY permission (to accommodate locally dumping a batch of many transactions).
This replaces #19184, rebased on #18044 and with many small changes.

This requires slightly reorganizing the logic in GETBLOCKTXN to
maintain locking order.

This helps distinguish the member from any local variables.

|

Whenever a transaction is added to the mempool or orphan pool, both
its txid and wtxid are considered AlreadyHave, and thus will eventually
be removed from m_txrequest.
The same is true for hashes added to the reject filter, but note that sometimes
only the wtxid is added (in which case only the wtxid can be removed from
m_txrequest).
|
|
Maintaining up to 100000 INVs per peer is excessive, as that is far more
than fits in a typical mempool.
Also disable the "overload" penalty for PF_RELAY peers.
|
|
This removes most transaction request logic from net_processing, and
replaces it with calls to a global TxRequestTracker object.
The major changes are:
* Announcements from outbound (and whitelisted) peers are now always
preferred over those from inbound peers. This used to be the case for the
first request (by delaying the first request from inbound peers), and
a bias afters. The 2s delay for requests from inbound peers still exists,
but after that, if viable outbound peers remain for any given transaction,
they will always be tried first.
* No more hard cap of 100 in flight transactions per peer, as there is less
need for it (memory usage is linear in the number of announcements, but
independent from the number in flight, and CPU usage isn't affected by it).
Furthermore, if only one peer announces a transaction, and it has over 100
in flight and requestable already, we still want to request it from them.
The cap is replaced with an additional 2s delay (possibly combined with the
existing 2s delays for inbound connections, and for txid peers when wtxid
peers are available).
Includes functional tests written by Marco Falke and Antoine Riard.

Pull request description:
Picked up from #15810. Add separate fee-checking logic for clients that need to enforce max fee rates, then remove the `absurdFee` logic from ATMP.
ATMP's `nAbsurdFee` argument is used to enforce user-specific behavior (it is not policy since it isn't applied consistently: it is only ever used in RPC and wallet, and set to 0 everywhere else internally). It should be removed from `AcceptToMemoryPool` because (1) validation results/mempool behavior should not be user-specific and (2) enforcing a max fee rate should be the responsibility of the client instead of the mempool.
Note: this PR does not intend to _remove_ protection from high fees, just re-delegate the responsibility to clients.

Block-relay-only peers were introduced by #15759. According to its
author, it was intented to make them only immune to outbound peer
rotation-based eviction and not from all eviction as modified comment
leans to think of.
Clearly indicate that outbound block-relay peers aren't protected
from eviction by the bad/lagging chain logic.

Pull request description:
Inspired by #15206 and #15197, this PR moves all message header verification from the message processing layer and into the network/transport layer.
In the previous PRs there is a change in behavior, where we would disconnect from peers upon a single failed checksum check. In various discussions there was concern over whether this was the right choice, and some expressed a desire to see how this would look if it was made to be a pure refactor.
For more context, see https://bitcoincore.reviews/15206.html#l-81.
This PR improves the separation between the p2p layers, helping improvements like [BIP324](https://github.com/bitcoin/bitcoin/pull/18242) and #18989.

Pull request description:
After #19316, we can more directly expose information about the connection type on the `getpeerinfo` RPC. Doing so also makes the existing addnode field redundant, so this PR begins the process of deprecating this field.
This PR also includes one commit that improves a log message, as both use a shared function to return the connection type as a string.

This moves header size and netmagic checking out of net_processing and
into net. This check now runs in ReadHeader, so that net can exit early
out of receiving bytes from the peer. IsValid is now slimmed down, so
it no longer needs a MessageStartChars& parameter.
Additionally this removes the rest of the m_valid_* members from
CNetMessage.
|
|
This removes the m_valid_checksum member from CNetMessage. Instead,
GetMessage() returns an Optional.
Additionally, GetMessage() has been given an out parameter to be used to
hold error information. For now it is specifically a uint32_t used to
hold the raw size of the corrupt message.
The checksum check is now done in GetMessage.
|
|
In addition to adding more specificity to the log statement about the type of
connection, this change also consolidates two statements into one. Previously,
the second one should have never been hit, since block-relay connections would
match the "!IsInboundConn()" condition and return early.

e9a6d8b13b0558b17cdafbd32fd2663b4138ff11 p2p: Unify Send and Receive protocol versions (Hennadii Stepanov)
Pull request description:
On master (6fef85bfa3cd7f76e83b8b57f9e4acd63eb664ec) `CNode` has two members to keep protocol version:
- `nRecvVersion` for received messages
- `nSendVersion` for messages to send
After exchanging with `VERSION` and `VERACK` messages via protocol version `INIT_PROTO_VERSION`, both nodes set `nRecvVersion` _and_ `nSendVersion` to _the same_ value which is the greatest common protocol version.
This PR:
- replaces two `CNode` members, `nRecvVersion` `nSendVersion`, with `m_greatest_common_version`
- removes duplicated getter and setter
There is no change in behavior on the P2P network.

Pull request description:
This is a follow-up on #18991 which does 3 things:
- improves privacy of a node listening to multiple addresses via adding cache index by local socket addr (suggested [here](https://github.com/bitcoin/bitcoin/pull/18991#issuecomment-668219345))
- documents on the choice of 24h cache lifetime
- addresses nits from #18991

Pull request description:
Addresses some outstanding review comments from #18044
- reverts unbroadcast txids to a set instead of a map (simpler, communicates intent better, takes less space, no efficiency advantages of map)
- adds safety around two touchpoints (check for nullptr before dereferencing pointer, remove an inaccurate std::move operator)
- removes some dead code

The field m_protect is used to protect from eviction both by bad/lagging
chain and extra outbound peers logics. Outbound block-relay peers are
always excluded from this protection.
|
|
|
|
|
|
|
|
Also rename orphan_state to state. Both the comment and the variable
name are leftover from when this logic was part of ProcessMessage().
|
|
This starts empty, and is only added to if we're about to
exit the function (so we never read from it).
|
|
There is a keyword that allows us to break out of loops. Use it.
There's a small change in behaviour here: if we process multiple orphans
that are still orphans, then we'll only call mempool.check() once at the
end, instead of after processing each tx.
