9e071b00898aedd9632f105a22d976dc6dbc84b1 test: remove rapidcheck integration and tests (fanquake) Pull request description: Whilst the property tests are interesting, ultimately [rapidcheck](https://github.com/emil-e/rapidcheck) integration in this repository has not gained much traction. We have a limited number of tests, and they are rarely (if ever) run. Have discussed this with Chris Stewart.

(practicalswift) Pull request description: Add fuzzing harness for `ProcessMessage(...)`. Enables high-level fuzzing of the P2P layer. All code paths reachable from this fuzzer can be assumed to be reachable for an untrusted peer. Seeded from thin air (an empty corpus) this fuzzer reaches roughly 20 000 lines of code. To test this PR: ``` $ make distclean $ ./autogen.sh $ CC=clang CXX=clang++ ./configure --enable-fuzz \ --with-sanitizers=address,fuzzer,undefined $ make $ src/test/fuzz/process_message ā€¦ ``` Worth noting about this fuzzing harness: * To achieve a reasonable number of executions per seconds the state of the fuzzer is unfortunately not entirely reset between `test_one_input` calls. The set-up (`FuzzingSetup` ctor) and tear-down (`~FuzzingSetup`) work is simply too costly to be run on every iteration. There is a trade-off to handle here between a.) achieving high executions/second and b.) giving the fuzzer a totally blank slate for each call. Please let me know if you have any suggestion on how to improve this situation while maintaining >1000 executions/second. * To achieve optimal results when using coverage-guided fuzzing I've chosen to create one specialised fuzzing binary per message type (`process_message_addr`, `process_message_block`, `process_message_blocktxn `, etc.) and one general fuzzing binary (`process_message`) which handles all messages types. The latter general fuzzer can be seeded with inputs generated by the former specialised fuzzers. Happy fuzzing friends!

2020-02-12wallet: Improve LegacyScriptPubKeyMan::CanProvide script recognitionRussell Yanofsky
Make LegacyScriptPubKeyMan::CanProvide method able to recognize p2sh scripts when the redeem script is present in the mapScripts map without the p2sh script also having to be added to the mapScripts map. This restores behavior prior to https://github.com/bitcoin/bitcoin/pull/17261, which I think broke backwards compatibility with old wallet files by no longer treating addresses created by `addmultisigaddress` calls before #17261 as solvable. The reason why tests didn't fail with the CanProvide implementation in #17261 is because of a workaround added in 4a7e43e8460127a40a7895519587399feff3b682 "Store p2sh scripts in AddAndGetDestinationForScript", which masked the problem for new `addmultisigaddress` RPC calls without fixing it for multisig addresses already created in old wallet files. This change adds a lot of comments and allows reverting commit 4a7e43e8460127a40a7895519587399feff3b682 "Store p2sh scripts in AddAndGetDestinationForScript", so the AddAndGetDestinationForScript() function, CanProvide() method, and mapScripts map should all be more comprehensible

A particular attack which encouraged us to work on this issue is explained here [[Erebus Attack against Bitcoin Peer-to-Peer Network](https://erebus-attack.comp.nus.edu.sg/)] (by @muoitranduc) Instead of relying on /16 prefix to diversify the connections every node creates, we would instead rely on the (ip -> ASN) mapping, if this mapping is provided. A .map file can be created by every user independently based on a router dump, or provided along with the Bitcoin release. Currently we use the python scripts written by @sipa to create a .map file, which is no larger than 2MB (awesome!). Here I suggest adding a field to peers.dat which would represent a hash of asmap file used while serializing addrman (or 0 for /16 prefix legacy approach). In this case, every time the file is updated (or grouping method changed), all buckets will be re-computed. I believe that alternative selective re-bucketing for only updated ranges would require substantial changes. TODO: - ~~more unit tests~~ - ~~find a way to test the code without including >1 MB mapping file in the repo.~~ - find a way to check that mapping file is not corrupted (checksum?) - comments and separate tests for asmap.cpp - make python code for .map generation public - figure out asmap distribution (?) ~Interesting corner case: Iā€™m using std::hash to compute a fingerprint of asmap, and std::hash returns size_t. I guess if a user updates the OS to 64-bit, then the hash of asap will change?
