| * Replace setInventoryKnown with a rolling bloom filter.Gregory Maxwell2015-11-301-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | - Force AUTHCOOKIE size to be 32 bytes: This provides protection against an attack where a process pretends to be Tor and uses the cookie authentication method to nab arbitrary files such as the wallet - torcontrol logging - fix cookie auth - add HASHEDPASSWORD auth, fix fd leak when fwrite() fails - better error reporting when cookie file is not ok - better init/shutdown flow - stop advertizing service when disconnected from tor control port - COOKIE->SAFECOOKIE auth
* 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.
* Introduce -maxuploadtargetJonas Schnelli2015-10-261-0/+94
| | | | | | | * -maxuploadtarget can be set in MiB * if <limit> - ( time-left-in-24h-cycle / 600 * MAX_BLOCK_SIZE ) has reach, stop serve blocks older than one week and filtered blocks * no action if limit has reached, no guarantee that the target will not be surpassed * add outbound limit informations to rpc getnettotals
* 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.
* net: correctly initialize nMinPingUsecTimeWladimir J. van der Laan2015-09-041-0/+1
| | | | | | `nMinPingUsecTime` was left uninitialized in CNode. The correct initialization for a minimum-until-now is int64_t's max value, so initialize it to that. Thanks @MarcoFalke for noticing.

* | Make CRollingBloomFilter set nTweak for youPeter Todd2015-07-271-1/+1
|/ | | | | | | | | | | | While CBloomFilter is usually used with an explicitly set nTweak, CRollingBloomFilter is only used internally. Requiring every caller to set nTweak is error-prone and redundant; better to have the class handle that for you with a high-quality randomness source. Additionally when clearing the filter it makes sense to change nTweak as well to recover from a bad setting, e.g. due to insufficient randomness at initialization, so the clear() method is replaced by a reset() method that sets a new, random, nTweak value.
