2021-07-15Add logging and addr rate limiting statisticsPieter Wuille
Includes logging improvements by Vasil Dimov and John Newbery.
2021-07-15Randomize the order of addr processingPieter Wuille
2021-07-15Rate limit the processing of incoming addr messagesPieter Wuille
While limitations on the influence of attackers on addrman already exist (affected buckets are restricted to a subset based on incoming IP / network group), there is no reason to permit them to let them feed us addresses at more than a multiple of the normal network rate. This commit introduces a "token bucket" rate limiter for the processing of addresses in incoming ADDR and ADDRV2 messages. Every connection gets an associated token bucket. Processing an address in an ADDR or ADDRV2 message from non-whitelisted peers consumes a token from the bucket. If the bucket is empty, the address is ignored (it is not forwarded or processed). The token counter increases at a rate of 0.1 tokens per second, and will accrue up to a maximum of 1000 tokens (the maximum we accept in a single ADDR or ADDRV2). When a GETADDR is sent to a peer, it immediately gets 1000 additional tokens, as we actively desire many addresses from such peers (this may temporarily cause the token count to exceed 1000). The rate limit of 0.1 addr/s was chosen based on observation of honest nodes on the network. Activity in general from most nodes is either 0, or up to a maximum around 0.025 addr/s for recent Bitcoin Core nodes. A few (self-identified, through subver) crawler nodes occasionally exceed 0.1 addr/s.
2021-06-29[refactor] Add deploymentstatus.hAnthony Towns
Provides DeploymentEnabled, DeploymentActiveAt, and DeploymentActiveAfter helpers for checking the status of buried deployments. Can be overloaded so the same syntax works for non-buried deployments, allowing future soft forks to be changed from signalled to buried deployments without having to touch the implementation code. Replaces IsWitnessEnabled and IsScriptWitnessEnabled.

I reviewed this previously as part of #21391. I am a fan of the increasingly complicated bundle numbering, and kind of hope there in the next round there is some way we can get bundles 5.333333 and 5.666667! jamesob: ACK 693414d27181cf967f787a2ca72344e52c58c7f0 ([`jamesob/ackr/21525.1.dongcarl.bundle_4_5_n_followup_f`](https://github.com/jamesob/bitcoin/tree/ackr/21525.1.dongcarl.bundle_4_5_n_followup_f)) Tree-SHA512: 9bdc199f70400d01764e1bd03c25bdb6cff26dcef60e4ca3b649baf8d017a2dfc1f058099067962b4b6ccd32d078002b1389d733039f4c337558cb70324c0ee3

It refactors `addr` send functionality into its own function `MaybeSendAddr()` and flattens/simplifies the code. Isolating and simplifying the addr handling code makes subsequent changes (which will move addr data and logic into net processing) easier to review. This is a pure refactor. There are no functional changes. For motivation of the project, see #19398.

2021-03-31[net processing] Refactor MaybeSendAddr()John Newbery
Changes to make MaybeSendAddr simpler and easier to maintain/update: - assert invariant that node.vAddrToSend.size() can never exceed MAX_ADDR_TO_SEND - erase known addresses from vAddrToSend in one pass - no check for (vAddr.size() >= MAX_ADDR_TO_SEND) during iteration, since vAddr can never exceed MAX_ADDR_TO_SEND.

Make it a top-level component with lifetime owned by node.context, and add a reference to addrman in peerman. This allows us to eliminate some functions in connman that are simply forwarding requests to addrman, and simplifies the connman-peerman interface. By constructing the addrman in init, we can also add parameters to the ctor, which allows us to test it better. See #20233, where we enable consistency checking for addrman in our functional tests.
