Felföldi Zsolt	25982375a8	les: fix retriever logic (#16776) ... This PR fixes a retriever logic bug. When a peer had a soft timeout and then a response arrived, it always assumed it was the same peer even though it could have been a later requested one that did not time out at all yet. In this case the logic went to an illegal state and deadlocked, causing a goroutine leak. Fixes #16243 and replaces #16359. Thanks to @riceke for finding the bug in the logic.	7 years ago

Felföldi Zsolt	ca376ead88	les, light: LES/2 protocol version (#14970) ... This PR implements the new LES protocol version extensions: * new and more efficient Merkle proofs reply format (when replying to a multiple Merkle proofs request, we just send a single set of trie nodes containing all necessary nodes) * BBT (BloomBitsTrie) works similarly to the existing CHT and contains the bloombits search data to speed up log searches * GetTxStatusMsg returns the inclusion position or the pending/queued/unknown state of a transaction referenced by hash * an optional signature of new block data (number/hash/td) can be included in AnnounceMsg to provide an option for "very light clients" (mobile/embedded devices) to skip expensive Ethash check and accept multiple signatures of somewhat trusted servers (still a lot better than trusting a single server completely and retrieving everything through RPC). The new client mode is not implemented in this PR, just the protocol extension.	7 years ago
Felföldi Zsolt	a5d08c893d	les: code refactoring (#14416) ... This commit does various code refactorings: - generalizes and moves the request retrieval/timeout/resend logic out of LesOdr (will be used by a subsequent PR) - reworks the peer management logic so that all services can register with peerSet to get notified about added/dropped peers (also gets rid of the ugly getAllPeers callback in requestDistributor) - moves peerSet, LesOdr, requestDistributor and retrieveManager initialization out of ProtocolManager because I believe they do not really belong there and the whole init process was ugly and ad-hoc	7 years ago
