From a9ecbdfcaa15499644d16e9c8ad2c63dfc45b37b Mon Sep 17 00:00:00 2001 From: Sebastian Falbesoner Date: Mon, 6 Apr 2020 19:54:49 +0200 Subject: [PATCH] test: add more inactive filter tests to p2p_filter.py check the following expected behaviors if no filter is set: -> filtered block requests are ignored by the node -> sending a 'filteradd' message is treated as misbehavior (i.e. the peer's banscore increases by 100) also fixes a bug in the on_inv() callback method, which directly modified the type from BLOCK to FILTERED_BLOCK in the received 'inv' message rather than just for the reply Co-authored-by: MarcoFalke --- test/functional/p2p_filter.py | 26 ++++++++++++++++++++++---- 1 file changed, 22 insertions(+), 4 deletions(-) diff --git a/test/functional/p2p_filter.py b/test/functional/p2p_filter.py index 188b130a570..0146a3fe0ad 100755 --- a/test/functional/p2p_filter.py +++ b/test/functional/p2p_filter.py @@ -7,18 +7,20 @@ Test BIP 37 """ from test_framework.messages import ( + CInv, MSG_BLOCK, MSG_FILTERED_BLOCK, - msg_getdata, - msg_filterload, msg_filteradd, msg_filterclear, + msg_filterload, + msg_getdata, ) from test_framework.mininode import ( P2PInterface, mininode_lock, ) from test_framework.test_framework import BitcoinTestFramework +from test_framework.util import assert_equal class FilterNode(P2PInterface): @@ -38,8 +40,9 @@ class FilterNode(P2PInterface): for i in message.inv: # inv messages can only contain TX or BLOCK, so translate BLOCK to FILTERED_BLOCK if i.type == MSG_BLOCK: - i.type = MSG_FILTERED_BLOCK - want.inv.append(i) + want.inv.append(CInv(MSG_FILTERED_BLOCK, i.hash)) + else: + want.inv.append(i) if len(want.inv): self.send_message(want) @@ -104,6 +107,21 @@ class FilterTest(BitcoinTestFramework): txid = self.nodes[0].sendtoaddress(self.nodes[0].getnewaddress(), 7) filter_node.wait_for_tx(txid) + self.log.info('Check that request for filtered blocks is ignored if no filter is set') + filter_node.merkleblock_received = False + filter_node.tx_received = False + with self.nodes[0].assert_debug_log(expected_msgs=['received getdata']): + block_hash = self.nodes[0].generatetoaddress(1, self.nodes[0].getnewaddress())[0] + filter_node.wait_for_inv([CInv(MSG_BLOCK, int(block_hash, 16))]) + filter_node.sync_with_ping() + assert not filter_node.merkleblock_received + assert not filter_node.tx_received + + self.log.info('Check that sending "filteradd" if no filter is set is treated as misbehavior (+100)') + assert_equal(self.nodes[0].getpeerinfo()[0]['banscore'], 0) + filter_node.send_and_ping(msg_filteradd(data=b'letsmisbehave')) + assert_equal(self.nodes[0].getpeerinfo()[0]['banscore'], 100) + self.log.info("Check that division-by-zero remote crash bug [CVE-2013-5700] is fixed") filter_node.send_and_ping(msg_filterload(data=b'', nHashFuncs=1)) filter_node.send_and_ping(msg_filteradd(data=b'letstrytocrashthisnode'))
