From a96c1a46d4b3854252de75cbe09458ad5d1aecb0 Mon Sep 17 00:00:00 2001 From: moneromooo-monero Date: Thu, 4 Jul 2019 21:44:43 +0000 Subject: [PATCH] cryptonote_protocol: drop peers we can't download from when syncing Any peer that's behind us while syncing is useless to us (though not to them). This ensures that we don't get our peer slots filled with peers that we can't use. Once we've synced, we can connect to them and they can then sync off us if they want. --- src/cryptonote_protocol/cryptonote_protocol_handler.inl | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/src/cryptonote_protocol/cryptonote_protocol_handler.inl b/src/cryptonote_protocol/cryptonote_protocol_handler.inl index b38407840..03d04a074 100644 --- a/src/cryptonote_protocol/cryptonote_protocol_handler.inl +++ b/src/cryptonote_protocol/cryptonote_protocol_handler.inl @@ -341,6 +341,11 @@ namespace cryptonote if(m_core.have_block(hshd.top_id)) { + if (target > hshd.current_height) + { + MINFO(context << "peer is not ahead of us and we're syncing, disconnecting"); + return false; + } context.m_state = cryptonote_connection_context::state_normal; if(is_inital && target == m_core.get_current_blockchain_height()) on_connection_synchronized();
