| * | Only send one GetAddr response per connection.Gregory Maxwell2016-04-111-0/+1
| | | | | | | | | | | | | | | | | | This conserves resources from abusive peers that just send getaddr in a loop. Also makes correlating addr messages against INVs less effective.

|/ / | | | | | | | | | | | | Previously we used the CInv that would be sent to the peer announcing the transaction as the key, but using the txid instead allows us to decouple the p2p layer from the application logic (which relies on this map to avoid duplicate tx requests).
* | Implement "feefilter" P2P message.Alex Morcos2016-03-211-8/+12
| | | | | | | | The "feefilter" p2p message is used to inform other nodes of your mempool min fee which is the feerate that any new transaction must meet to be accepted to your mempool. This will allow them to filter invs to you according to this feerate.

* | | Decide eviction group ties based on time.Gregory Maxwell2016-02-011-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This corrects a bug the case of tying group size where the code may fail to select the group with the newest member. Since newest time is the final selection criteria, failing to break ties on it on the step before can undermine the final selection. Tied netgroups are very common. (cherry picked from commit 8e09f914f8ec66301257358b250e9a61befadd95)
* | | Do not absolutely protect local peers from eviction.Gregory Maxwell2016-02-011-2/+0
|/ / | | | | | | | | | | | | | | | | With automatic tor HS support in place we should probably not be providing absolute protection for local peers, since HS inbound could be used to attack pretty easily. Instead, this counts on the latency metric inside AttemptToEvictConnection to privilege actually local peers. (cherry picked from commit 46dbcd4833115401fecbb052365b4c7725874414)

| | | | | | | | | | | | | | | | | | | | | | | | - allows CNode::SweepBanned() to run, even if !CNode::BannedSetIsDirty(), because if nBanUntil is over we want the ban to be disabled for these nodes

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - to match the peers.dat handling also supply a debug.log entry for how many entries were loaded from banlist.dat and how long it took - add a GUI init message for loading the banlist (same as with peers.dat) - move the same message for peers.dat upwards in the code, to be able to reuse the timing variable nStart and also just log, if our read from peers.dat didn't fail
| * | | banlist: better handling of banlist in StartNode()Philip Kaufmann2015-10-021-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - only start working on/with banlist data, if reading in the banlist from disk didn't fail - as CNode::setBannedIsDirty is false (default) when reading fails, we don't need to explicitly set it to false to prevent writing banlist.dat in that case either
| * | | banlist: update set dirty to be more fine grainedPhilip Kaufmann2015-10-021-7/+4
| | | | | | | | | | | | | | | | | | | | - move the SetBannedSetDirty(false) call from DumpData() into DumpBanlist() - ensure we only set false, if the write succeeded

* | | | Replace trickle nodes with per-node/message Poisson delaysPieter Wuille2015-12-111-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We used to have a trickle node, a node which was chosen in each iteration of the send loop that was privileged and allowed to send out queued up non-time critical messages. Since the removal of the fixed sleeps in the network code, this resulted in fast and attackable treatment of such broadcasts. This pull request changes the 3 remaining trickle use cases by random delays: * Local address broadcast (while also removing the the wiping of the seen filter) * Address relay * Inv relay (for transactions; blocks are always relayed immediately) The code is based on older commits by Patrick Strateman.
* | | | net: Add and document network messages in protocol.hWladimir J. van der Laan2015-12-101-11/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Avoids string typos (by making the compiler check) - Makes it easier to grep for handling/generation of a certain message type - Refer directly to documentation by following the symbol in IDE - Move list of valid message types to protocol.cpp: protocol.cpp is a more appropriate place for this, and having the array there makes it easier to keep things consistent.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mruset setInventoryKnown was reduced to a remarkably small 1000 entries as a side effect of sendbuffer size reductions in 2012. This removes setInventoryKnown filtering from merkleBlock responses because false positives there are especially unattractive and also because I'm not sure if there aren't race conditions around the relay pool that would cause some transactions there to be suppressed. (Also, ProcessGetData was accessing setInventoryKnown without taking the required lock.)

| * | | Limit setAskFor and retire requested entries only when a getdata returns.Gregory Maxwell2015-11-231-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | The setAskFor duplicate elimination was too eager and removed entries when we still had no getdata response, allowing the peer to keep INVing and not responding.
| * | | prevent peer flooding request queue for an invkazcw2015-11-231-0/+4
| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mapAlreadyAskedFor does not keep track of which peer has a request queued for a particular tx. As a result, a peer can blind a node to a tx indefinitely by sending many invs for the same tx, and then never replying to getdatas for it. Each inv received will be placed 2 minutes farther back in mapAlreadyAskedFor, so a short message containing 10 invs would render that tx unavailable for 20 minutes. This is fixed by disallowing a peer from having more than one entry for a particular inv in mapAlreadyAskedFor at a time.

* | net: Automatically create hidden service, listen on TorWladimir J. van der Laan2015-11-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Starting with Tor version 0.2.7.1 it is possible, through Tor's control socket API, to create and destroy 'ephemeral' hidden services programmatically. https://stem.torproject.org/api/control.html#stem.control.Controller.create_ephemeral_hidden_service This means that if Tor is running (and proper authorization is available), bitcoin automatically creates a hidden service to listen on, without user manual configuration. This will positively affect the number of available .onion nodes. - When the node is started, connect to Tor through control socket - Send `ADD_ONION` command - First time: - Make it create a hidden service key - Save the key in the data directory for later usage - Make it redirect port 8333 to the local port 8333 (or whatever port we're listening on). - Keep control socket connection open for as long node is running. The hidden service will (by default) automatically go away when the connection is closed.

* | Set TCP_NODELAY on P2P sockets.Gregory Maxwell2015-10-221-0/+12
|/ | | | | | | | Nagle appears to be a significant contributor to latency now that the static sleeps are gone. Most of our messages are relatively large compared to IP + TCP so I do not expect this to create enormous overhead. This may also reduce traffic burstyness somewhat.
