2019-03-01[addrman] Improve collision logging and address nitsSuhas Daftuar
2019-02-27[net] feeler connections can be made to outbound peers in same netgroupSuhas Daftuar
Fixes a bug where feelers could be stuck trying to resolve a collision in the tried table that is to an address in the same netgroup as an existing outbound peer. Thanks to Muoi Tran for the original bug report and detailed debug logs to track this down.

2019-02-04net: Correct comparison of addr countCarl Dong
LOCAL_NONE is supposed to be an enum indicating the score of a LocalServiceInfo rather than the count of an addr in mapLocalHost.

"The AI_ADDRCONFIG flag is defined on the Windows SDK for Windows Vista and later. The AI_ADDRCONFIG flag is supported on Windows Vista and later." https://docs.microsoft.com/en-us/windows/desktop/api/ws2tcpip/nf-ws2tcpip-getaddrinfo However, the version of MinGW we use on Travis is not current and does not carry the relevant definition, as such I defined it in compat. https://github.com/wine-mirror/wine/blob/master/include/ws2tcpip.h Testing confirms that the PROTECTION_LEVEL_UNRESTRICTED, IPV6_PROTECTION_LEVEL, PROCESS_DEP_ENABLE, AI_ADDRCONFIG, are now supported by the version of Windows that we test against, so can be removed. https://travis-ci.org/bitcoin/bitcoin/jobs/483255439 https://travis-ci.org/Empact/bitcoin/jobs/484123087
2019-01-22Allow connections from misbehavior banned peers.Gregory Maxwell
This allows incoming connections from peers which are only banned due to an automatic misbehavior ban if doing so won't fill inbound. These peers are preferred for eviction when inbound fills, but may still be kept if they fall into the protected classes. This eviction preference lasts the entire life of the connection even if the ban expires. If they misbehave again they'll still get disconnected. The main purpose of banning on misbehavior is to prevent our connections from being wasted on unhelpful peers such as ones running incompatible consensus rules. For inbound peers this can be better accomplished with eviction preferences. A secondary purpose was to reduce resource waste from repeated abuse but virtually any attacker can get a nearly unlimited supply of addresses, so disconnection is about the best we can do.

2019-01-16banman: pass the banfile path inCory Fields
There's no need to hard-code the path here. Passing it in means that there are no ordering concerns wrt establishing the datadir.

These are separate events which need to be carried out by separate subsystems. This also cleans up some whitespace and tabs in qt to avoid getting flagged by the linter. Current behavior is preserved.

Previously, we relied on a comment to inform us of the timeout amount being tested. Now it is specified directly in the test via passing in the new arg; `-peertimeout=3`. - Opens us up to testing more P2P scenarios; oftentimes slow tests are the reason we don't test. **Locally verified changes:** _With Proposed Change (4.7 sec.):_ ``` $ time ./test/functional/p2p_timeouts.py 2018-11-19T00:04:19.077000Z TestFramework (INFO): Initializing test directory /tmp/testhja7g2n7 2018-11-19T00:04:23.479000Z TestFramework (INFO): Stopping nodes 2018-11-19T00:04:23.683000Z TestFramework (INFO): Cleaning up /tmp/testhja7g2n7 on exit 2018-11-19T00:04:23.683000Z TestFramework (INFO): Tests successful real 0m4.743s ``` _Currently on master (62.8 sec.):_ ``` $ time ./test/functional/p2p_timeouts.py 2018-11-19T00:06:10.948000Z TestFramework (INFO): Initializing test directory /tmp/test6mo6k21h 2018-11-19T00:07:13.376000Z TestFramework (INFO): Stopping nodes 2018-11-19T00:07:13.631000Z TestFramework (INFO): Cleaning up /tmp/test6mo6k21h on exit 2018-11-19T00:07:13.631000Z TestFramework (INFO): Tests successful real 1m2.836s ``` _Error message demonstrated for new argument `-peertimeout`:_ ``` $ ./bitcoind -peertimeout=-5 ...
