* | Merge #8707: net: fix maxuploadtarget settingWladimir J. van der Laan2016-09-191-2/+3
|\ \ | |/ |/| | | f3552da net: fix maxuploadtarget setting (Cory Fields)
| * net: fix maxuploadtarget settingCory Fields2016-09-141-2/+3
| | | | | | | | | | | | | | | | | | This was broken by 63cafa6329e1a. Note that while this fixes the settings, it doesn't fix the actual usage of -maxuploadtarget completely, as there is currently a bug in the nOptimisticBytesWritten accounting that causes a delayed response if the target is reached. That bug will be addressed separately.
* | net: No longer send local address in addrMeWladimir J. van der Laan2016-09-151-1/+1
|/ | | | | | | | | After #8594 the addrFrom sent by a node is not used anymore at all, so don't bother sending it. Also mitigates the privacy issue in (#8616). It doesn't completely solve the issue as GetLocalAddress is also called in AdvertiseLocal, but at least when advertising addresses it stands out less as *our* address.
* Merge #8715: net: only delete CConnman if it's been createdWladimir J. van der Laan2016-09-141-0/+1

| * net: only delete CConnman if it's been createdCory Fields2016-09-131-0/+1
| | | | | | | | | | | | | | | | In the case of (for example) an already-running bitcoind, the shutdown sequence begins before CConnman has been created, leading to a null-pointer dereference when g_connman->Stop() is called. Instead, Just let the CConnman dtor take care of stopping.

* net: Pass best block known height into CConnmanCory Fields2016-09-081-12/+24
| | | | | | | | | | | | | | | | | | | | CConnman then passes the current best height into CNode at creation time. This way CConnman/CNode have no dependency on main for height, and the signals only move in one direction. This also helps to prevent identity leakage a tiny bit. Before this change, an attacker could theoretically make 2 connections on different interfaces. They would connect fully on one, and only establish the initial connection on the other. Once they receive a new block, they would relay it to your first connection, and immediately commence the version handshake on the second. Since the new block height is reflected immediately, they could attempt to learn whether the two connections were correlated. This is, of course, incredibly unlikely to work due to the small timings involved and receipt from other senders. But it doesn't hurt to lock-in nBestHeight at the time of connection, rather than letting the remote choose the time.

| | | | | These are in-turn passed to CNode at connection time. This allows us to offer different services to different peers (or test the effects of doing so).

| | | | | | | | This behavior seems to have been quite racy and broken. Move nLocalHostNonce into CNode, and check received nonces against all non-fully-connected nodes. If there's a match, assume we've connected to ourself.

* | | Added feeler connections increasing good addrs in the tried table.Ethan Heilman2016-08-231-8/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | Tests if addresses are online or offline by briefly connecting to them. These short lived connections are referred to as feeler connections. Feeler connections are designed to increase the number of fresh online addresses in tried by selecting and connecting to addresses in new. One feeler connection is attempted on average once every two minutes. This change was suggested as Countermeasure 4 in Eclipse Attacks on Bitcoin’s Peer-to-Peer Network, Ethan Heilman, Alison Kendler, Aviv Zohar, Sharon Goldberg. ePrint Archive Report 2015/263. March 2015.
