PoW connection slots to handle DDoS slot exhaustion attacks #2

kallewoof · 2017-03-25T19:06:53Z

Code is experimental but it works. It drops settings down heavily for easy testing. Normally, you would have something like 75 free slots and 50 POW slots or something (in bitcoin default there are 125 free slots).

The code:

adds cuckoo cycle POW support, to force the connector to use CPU resources to solve the challenge,
adds SHA256 POW support,
adds a new ados namespace which facilitates solving and challenging
adds two new commands to the network peer protocol: CHALLENGE and SOLUTION
adds a new service bit called NODE_DOSPROT (1<<5) which indicates the node is able to do POW for services (may be used e.g. for bloom filters as a quick hack before they are replaced).

…tion d31e5c1 Fix shutdown in case of errors during initialization (Wladimir J. van der Laan) Pull request description: PR bitcoin#10286 introduced a few steps which are not robust to early shutdown in initialization. Stumbled upon this with bitcoin#11781, not sure if there are other scenarios that can trigger it, but it's good to harden against this in any case. E.g. ``` $ src/bitcoind -debuglogfile=/dfdf Error: Could not open debug log file /dfdf Program received signal SIGSEGV, Segmentation fault.

…avoid deprecated zeromq api functions f1bd03e [depends, zmq, doc] upgrade zeromq to 4.2.5 and avoid deprecated zeromq api functions (mruddy) Pull request description: Upgrade the ZeroMQ dependency from version 4.2.3 to the latest stable version 4.2.5. This PR Follows the lead of bitcoin#11986. I upgraded both patch files to correspond to the version `4.2.5` libzmq files. I assume doing so is still necessary and correct. Without updating the patch line numbers, things appear to work, but you get extra log messages while building `depends` because things don't exactly match, e.g.: ``` /bitcoin/depends> make zeromq Extracting zeromq... /bitcoin/depends/sources/zeromq-4.2.5.tar.gz: OK Preprocessing zeromq... patching file src/windows.hpp Hunk #1 succeeded at 58 (offset 3 lines). patching file src/thread.cpp Hunk #1 succeeded at 307 with fuzz 2 (offset 87 lines). Hunk #2 succeeded at 323 with fuzz 2 (offset 90 lines). ``` Updating the patches seemed cleaner, so I did it. Note that libzmq had some whitespace changes, so that's why the updated patches do too.

… harness (descriptor_parse) 6338c02 tests: Fix fuzzing harness for descriptor parsing (descriptor_parse) (practicalswift) Pull request description: Fix bug in the descriptor parsing fuzzing harness (`descriptor_parse`) by making sure `secp256k1_context_verify` is properly initialized (via `ECCVerifyHandle`). Background: When fuzzing `Parse(…)` with `libFuzzer` I eventually reached the test case `combo(020000000000000000000000000000000000000000000000000000000000000000)`. That input triggers a call to `CPubKey::IsFullyValid()` which in turns requires an initialized `secp256k1_context_verify`. The fuzzing harness did not fulfil that pre-condition prior to this commit (sorry, my fault!) :) Before: ``` $ mkdir descriptors/ $ echo -n 'combo(020000000000000000000000000000000000000000000000000000000000000000)' > descriptors/input $ UBSAN_OPTIONS="print_stacktrace=1:halt_on_error=1" src/test/fuzz/descriptor_parse -runs=1 descriptors/ … pubkey.cpp:210:38: runtime error: null pointer passed as argument 1, which is declared to never be null secp256k1/include/secp256k1.h:305:3: note: nonnull attribute specified here #0 0x561c032ccf25 in CPubKey::IsFullyValid() const src/pubkey.cpp:210:12 #1 0x561c022139c3 in (anonymous namespace)::ParsePubkeyInner(Span<char const> const&, bool, FlatSigningProvider&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&) src/script/descriptor.cpp:674:24 #2 0x561c02207680 in (anonymous namespace)::ParsePubkey(Span<char const> const&, bool, FlatSigningProvider&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&) src/script/descriptor.cpp:730:42 #3 0x561c0220080e in (anonymous namespace)::ParseScript(Span<char const>&, (anonymous namespace)::ParseScriptContext, FlatSigningProvider&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&) src/script/descriptor.cpp:774:23 #4 0x561c021ffb07 in Parse(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, FlatSigningProvider&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&, bool) src/script/descriptor.cpp:994:16 #5 0x561c0218d5d4 in test_one_input(std::vector<unsigned char, std::allocator<unsigned char> > const&) src/test/fuzz/descriptor_parse.cpp:20:9 … $ ``` After: ``` $ mkdir descriptors/ $ echo -n 'combo(020000000000000000000000000000000000000000000000000000000000000000)' > descriptors/input $ UBSAN_OPTIONS="print_stacktrace=1:halt_on_error=1" src/test/fuzz/descriptor_parse -runs=1 descriptors/ … Done 2 runs in 0 second(s) $ ``` ACKs for top commit: paymog: ACK 6338c02 MarcoFalke: ACK 6338c02 🕊 Tree-SHA512: bf24c404e1f64183761b057d2f210c3db85277f4415122977c315d7d6835acb5e897b5d64032615e9e44ad4a16dfe857e94481f6e4b57b6dfa8cb37adb2528a5

… in libevent when handling PROXY requests 20d31bd tests: Avoid fuzzer-specific nullptr dereference in libevent when handling PROXY requests (practicalswift) Pull request description: Avoid constructing requests that will be interpreted by libevent as PROXY requests to avoid triggering a `nullptr` dereference. Split out from bitcoin#19074 as suggested by MarcoFalke. The dereference (`req->evcon->http_server`) takes place in `evhttp_parse_request_line` and is a consequence of our hacky but necessary use of the internal function `evhttp_parse_firstline_` in the `http_request` fuzzing harness. The suggested workaround is not aesthetically pleasing, but it successfully avoids the troublesome code path. `" http:// HTTP/1.1\n"` was a crashing input prior to this workaround.

…lock orders 0ecff9d Improve "detected inconsistent lock order" error message (Hennadii Stepanov) bbe9cf4 test: Improve "potential deadlock detected" exception message (Hennadii Stepanov) 3559934 Fix mistakenly swapped "previous" and "current" lock orders (Hennadii Stepanov) Pull request description: In master (8ef15e8) the "previous" and "current" lock orders are mistakenly swapped. This PR: - fixes printed lock orders - improves the `sync_tests` unit test - makes the "detected inconsistent lock order" error message pointing to the lock location rather `tfm::format()` location. Debugger output example with this PR (with modified code, of course): ``` 2020-06-22T15:46:56Z [msghand] POTENTIAL DEADLOCK DETECTED 2020-06-22T15:46:56Z [msghand] Previous lock order was: 2020-06-22T15:46:56Z [msghand] (2) 'cs_main' in net_processing.cpp:2545 (in thread 'msghand') 2020-06-22T15:46:56Z [msghand] (1) 'g_cs_orphans' in net_processing.cpp:1400 (in thread 'msghand') 2020-06-22T15:46:56Z [msghand] Current lock order is: 2020-06-22T15:46:56Z [msghand] (1) 'g_cs_orphans' in net_processing.cpp:2816 (in thread 'msghand') 2020-06-22T15:46:56Z [msghand] (2) 'cs_main' in net_processing.cpp:2816 (in thread 'msghand') Assertion failed: detected inconsistent lock order for 'cs_main' in net_processing.cpp:2816 (in thread 'msghand'), details in debug log.

fac04cb refactor: Add lock annotations to Active* methods (MacroFake) fac15ff Fix logical race in rest_getutxos (MacroFake) fa97a52 Fix UB/data-race in RPCNotifyBlockChange (MacroFake) fa530bc Add ChainstateManager::GetMutex(), an alias for ::cs_main (MacroFake) Pull request description: This fixes two issues: * A data race in `ActiveChain`, which returns a reference to the chain (a `std::vector`), which is not thread safe. See also below traceback. * A corrupt rest response, which returns a blockheight and blockhash, which are unrelated to each other and to the result, as the chain might advance between each call without cs_main held. The issues are fixed by taking cs_main and holding it for the required time. ``` ================== WARNING: ThreadSanitizer: data race (pid=32335) Write of size 8 at 0x7b3c000008f0 by thread T22
