The fix on BSC repo: https://github.com/bnb-chain/bsc/pull/3347 When the hang occurs, there are two routines stuck. - routine 1: AsyncFilter(...) On node start, it will run part of the DiscoveryV4 protocol, which could take considerable time, here is its hang callstack: ``` goroutine 9711 [chan receive]: // this routine was stuck on read channel: `<-f.slots` github.com/ethereum/go-ethereum/p2p/enode.AsyncFilter.func1() github.com/ethereum/go-ethereum/p2p/enode/iter.go:206 +0x125 created by github.com/ethereum/go-ethereum/p2p/enode.AsyncFilter in goroutine 1 github.com/ethereum/go-ethereum/p2p/enode/iter.go:192 +0x205 ``` - Routine 2: Node Stop It is the main routine to shutdown the process, but it got stuck when it tries to shutdown the discovery components, as it tries to drain the channel of `<-f.slots`, but the extra 1 slot will never have chance to be resumed. ``` goroutine 11796 [chan receive]: github.com/ethereum/go-ethereum/p2p/enode.(*asyncFilterIter).Close.func1() github.com/ethereum/go-ethereum/p2p/enode/iter.go:248 +0x5c sync.(*Once).doSlow(0xc032a97cb8?, 0xc032a97d18?) sync/once.go:78 +0xab sync.(*Once).Do(...) sync/once.go:69 github.com/ethereum/go-ethereum/p2p/enode.(*asyncFilterIter).Close(0xc092ff8d00?) github.com/ethereum/go-ethereum/p2p/enode/iter.go:244 +0x36 github.com/ethereum/go-ethereum/p2p/enode.(*bufferIter).Close.func1() github.com/ethereum/go-ethereum/p2p/enode/iter.go:299 +0x24 sync.(*Once).doSlow(0x11a175f?, 0x2bfe63e?) sync/once.go:78 +0xab sync.(*Once).Do(...) sync/once.go:69 github.com/ethereum/go-ethereum/p2p/enode.(*bufferIter).Close(0x30?) github.com/ethereum/go-ethereum/p2p/enode/iter.go:298 +0x36 github.com/ethereum/go-ethereum/p2p/enode.(*FairMix).Close(0xc0004bfea0) github.com/ethereum/go-ethereum/p2p/enode/iter.go:379 +0xb7 github.com/ethereum/go-ethereum/eth.(*Ethereum).Stop(0xc000997b00) github.com/ethereum/go-ethereum/eth/backend.go:960 +0x4a github.com/ethereum/go-ethereum/node.(*Node).stopServices(0xc0001362a0, {0xc012e16330, 0x1, 0xc000111410?}) github.com/ethereum/go-ethereum/node/node.go:333 +0xb3 github.com/ethereum/go-ethereum/node.(*Node).Close(0xc0001362a0) github.com/ethereum/go-ethereum/node/node.go:263 +0x167 created by github.com/ethereum/go-ethereum/cmd/utils.StartNode.func1.1 in goroutine 9729 github.com/ethereum/go-ethereum/cmd/utils/cmd.go:101 +0x78 ``` The rootcause of the hang is caused by the extra 1 slot, which was designed to make sure the routines in `AsyncFilter(...)` can be finished. This PR fixes it by making sure the extra 1 shot can always be resumed when node shutdown. ✖ body's lines must not be longer than 100 characters [body-max-line-length] ✖ header must not start with whitespace [header-trim] ✖ found 2 problems, 0 warnings ⓘ Get help: https://github.com/bnb-chain/bsc/tree/develop/docs/lint/commit.md ⧗ input: accounts/abi: check presence of payable fallback or receive before proceeding with transfer (#32374) remove todo ✖ header must not be longer than 80 characters, current length is 100 [header-max-length] ✖ found 1 problems, 0 warnings ⓘ Get help: https://github.com/bnb-chain/bsc/tree/develop/docs/lint/commit.md ⧗ input: eth/protocols/eth: reject message containing duplicated txs and drop peer (#32728) Drop peer if sending the same transaction multiple times in a single message.
