2021-06-16fuzz: fix fuzz binary linking orderSjors Provoost
We encountered a linking error when attempting to include external_signer_scriptpubkeyman.cpp when configured with --disable-external-signer. Everywhere else we have LIBBITCOIN_WALLET, it is always before LIBBITCOIN_COMMON. But if you go up to where FUZZ_SUITE_LD_COMMON is first set, you see that we will end up having LIBBITCOIN_COMMON set before LIBBITCOIN_WALLET which means that the linker will have problems linking things common things that the wallet uses. Because the order is correct for the other targets, we only see a linker error for test/fuzz/fuzz. In this diff, LIBTEST_UTIL and LIBTEST_FUZZ are moved to the top because they include LIBBITCOIN_SERVER and LIBBITCOIN_COMMON. LIBBITCOIN_SERVER always needs to be the first item in the linker order since it has the most dependencies. The makefiles for making the fuzz and test binaries should be revisited so that the linking order is made consistent with the rest of the code and to avoid other linker order issues that may crop up in the future.

2021-06-16Merge bitcoin/bitcoin#22144: Randomize message processing peer orderfanquake
79c02c88b347f1408a2db307db2654917f9b0bcc Randomize message processing peer order (Pieter Wuille) Pull request description: Right now, the message handling loop iterates the list of nodes always in the same order: the order they were connected in (see the `vNodes` vector). For some parts of the net processing logic, this order matters. Transaction requests are assigned explicitly to peers since #19988, but many other parts of processing work on a "first-served-by-loop-first" basis, such as block downloading. If peers can predict this ordering, it may be exploited to cause delays. As there isn't anything particularly optimal about the current ordering, just make it unpredictable by randomizing.

It then adds eviction protection for peers connected over I2P. As described in https://github.com/bitcoin/bitcoin/pull/20685#issuecomment-767486499, we've observed over the past few months that I2P peers have a min ping latency similar to or greater than that of onion peers. The algorithm is a basically a multi-pass knapsack: - Count the number of eviction candidates in each of the disadvantaged privacy networks. - Sort the networks from lower to higher candidate counts, so that a network with fewer candidates will have the first opportunity for any unused slots remaining from the previous iteration. In the case of a tie in candidate counts, priority is given by array member order from first to last, guesstimated to favor more unusual networks. - Iterate through the networks in this order. On each iteration, allocate each network an equal number of protected slots targeting a total number of candidates to protect, provided any slots remain in the knapsack. - Protect the candidates in that network having the longest uptime, if any in that network are present. - Continue iterating as long as we have non-allocated slots remaining and candidates available to protect. The goal of this logic is to favorise the diversity of our peer connections. The individual commit messages describe each change in more detail. Special thank you to Vasil Dimov for the excellent review feedback and the algorithm improvement that made this change much better than it would have been otherwise. Thanks also to Antoine Riard, whose review feedback nudged this change to protect disadvantaged networks having fewer, rather than more, eviction candidates.

2021-06-14p2p: extend inbound eviction protection by network to I2P peersJon Atack
This commit extends our inbound eviction protection to I2P peers to favorise the diversity of peer connections, as peers connected through the I2P network are otherwise disadvantaged by our eviction criteria for their higher latency (higher min ping times) relative to IPv4 and IPv6 peers, as well as relative to Tor onion peers. The `networks` array is order-dependent in the case of a tie in candidate counts between networks (earlier array members receive priority in the case of a tie). Therefore, we place I2P candidates before localhost and onion ones in terms of opportunity to recover unused remaining protected slots from the previous iteration, guesstimating that most nodes allowing both onion and I2P inbounds will have more onion peers, followed by localhost, then I2P, as I2P support is only being added in the upcoming v22.0 release.

2021-06-14p2p: make ProtectEvictionCandidatesByRatio() fully ratio-basedJon Atack
with a more abstract framework to allow easily extending inbound eviction protection to peers connected through new higher-latency networks that are disadvantaged by our inbound eviction criteria, such as I2P and perhaps other BIP155 networks in the future like CJDNS. This is a change in behavior. The algorithm is a basically a multi-pass knapsack: - Count the number of eviction candidates in each of the disadvantaged privacy networks. - Sort the networks from lower to higher candidate counts, so that a network with fewer candidates will have the first opportunity for any unused slots remaining from the previous iteration. In the case of a tie in candidate counts, priority is given by array member order from first to last, guesstimated to favor more unusual networks. - Iterate through the networks in this order. On each iteration, allocate each network an equal number of protected slots targeting a total number of candidates to protect, provided any slots remain in the knapsack. - Protect the candidates in that network having the longest uptime, if any in that network are present. - Continue iterating as long as we have non-allocated slots remaining and candidates available to protect. Localhost peers are treated as a network like Tor or I2P by aliasing them to an unused Network enumerator: Network::NET_MAX. The goal is to favorise diversity of our inbound connections.
