2017-11-09Do not make it trivial for inbound peers to generate log entriesMatt Corallo
We should generally avoid writing to debug.log unconditionally for inbound peers which misbehave (the peer being about to be banned being an exception, since they cannot do this twice). To avoid removing logs for outbound peers, a new log is added to notify users when a new outbound peer is connected which mimics the version print.

5ce7cb9 [net] De-duplicate connection eviction logic (Thomas Snider) Pull request description: While reviewing the safeguards against deliberate node isolation on the network by malicious actors, I found a good de-duplication candidate. I think this form is much more legible (the type of `cutoffs` notwithstanding). ReverseCompareNodeTimeConnected is not included in the list since the cutoff size is a function of the remaining number of nodes in the candidate eviction set.

2017-11-02Connect to an extra outbound peer if our tip is staleSuhas Daftuar
If our tip hasn't updated in a while, that may be because our peers are not relaying blocks to us that we would consider valid. Allow connection to an additional outbound peer in that circumstance. Also, periodically check to see if we are exceeding our target number of outbound peers, and disconnect the one which has least recently announced a new block to us (choosing the newest such peer in the case of tie).

2017-10-13Rename fAddnode to a more-descriptive "manual_connection"Matt Corallo
2017-10-13Replace relevant services logic with a function suite.Matt Corallo
Adds HasAllRelevantServices and GetRelevantServices, which check for NETWORK|WITNESS. This changes the following: * Removes nRelevantServices from CConnman, disconnecting it a bit more from protocol-level logic. * Replaces our sometimes-connect-to-!WITNESS-nodes logic with simply always requiring WITNESS|NETWORK for outbound non-feeler connections (feelers still only require NETWORK). * This has the added benefit of removing nServicesExpected from CNode - instead letting net_processing's VERSION message handling simply check HasAllRelevantServices. * This implies we believe WITNESS nodes to continue to be a significant majority of nodes on the network, but also because we cannot sync properly from !WITNESS nodes, it is strange to continue using our valuable outbound slots on them. * In order to prevent this change from preventing connection to -connect= nodes which have !WITNESS, -connect nodes are now given the "addnode" flag. This also allows outbound connections to !NODE_NETWORK nodes for -connect nodes (which was already true of addnodes). * Has the (somewhat unintended) consequence of changing one of the eviction metrics from the same sometimes-connect-to-!WITNESS-nodes metric to requiring HasRelevantServices. This should make NODE_NETWORK_LIMITED much simpler to implement.

It essentially breaks up two wrapper functions for things only used in one place (ConnectSocketDirectly/ConnectThroughProxy) in favor of calling them directly. This allows us to fully handle resolves before attempting a connection, as is necessary for async connections. As a bonus, I believe the logic is now much easier to follow than before.

2017-09-22Use static_cast instead of C-style casts for non-fundamental typespracticalswift
A C-style cast is equivalent to try casting in the following order: 1. const_cast(...) 2. static_cast(...) 3. const_cast(static_cast(...)) 4. reinterpret_cast(...) 5. const_cast(reinterpret_cast(...)) By using static_cast<T>(...) explicitly we avoid the possibility of an unintentional and dangerous reinterpret_cast. Furthermore static_cast<T>(...) allows for easier grepping of casts.
2017-09-18net: remove now-superfluous numeric resolveCory Fields
This was added in order to help OpenNetworkConnection avoid creating a connection that it would end up aborting. It was necessary because resolving was done as part of the connection process. Now that resolving is separated from connecting, this case is detected before the connection is attempted.
2017-09-18net: separate resolving and conectingCory Fields
ConnectSocketByName handled resolves as necessary, obscuring the connection process. With them separated, each can be handled asynchronously. Also, since proxies must be considered now anyway, go ahead and eliminate the ConnectSocket wrapper and use ConnectSocketDirectly... directly.

This commit adds a method Init(const Options& connOptions) which is called by both the constructor and CConnman::Start(...). This method initializes nLocalServices and the other relevant values from the supplied Options object.

2017-06-14net: add an internal subnet for representing unresolved hostnamesCory Fields
We currently do two resolves for dns seeds: one for the results, and one to serve in addrman as the source for those addresses. There's no requirement that the source hostname resolves to the stored identifier, only that the mapping is unique. So rather than incurring the second lookup, combine a private subnet with a hash of the hostname. The resulting v6 ip is guaranteed not to be publicy routable, and has only a negligible chance of colliding with a user's internal network (which would be of no consequence anyway).
