Wladimir J. van der Laan 9e5c9d0a04 torcontrol: Explicitly request RSA1024 private key
When generating a new service key, explicitly request a RSA1024 one.

The bitcoin P2P protocol has no support for the longer hidden service names
that will come with ed25519 keys, until it does, we depend on the old
hidden service type so make this explicit.

See #9214.

Wladimir J. van der Laan ca5e229514 tor: Change auth order to only use HASHEDPASSWORD if -torpassword
Change authentication order to make it more clear (see #7700).

- If the `-torpassword` option is provided, force use of
  `HASHEDPASSWORD` auth.

- Give error message if `-torpassword` provided, but
  `HASHEDPASSWORD` auth is not available.

- Give error message if only `HASHEDPASSWORD` available, but
  `-torpassword` not given.

Jonas Schnelli 1a41e3f660 Fix torcontrol.cpp unused private field warning 2017-03-25 20:25:48 +13:00
Wladimir J. van der Laan 3d7cddcaa2 Fix memleak in TorController [rework]
It looks like, TorController::disconnected_cb(TorControlConnection&
conn) gets called multiple times which results in multiple event_new().

Avoid this by creating the event only once in the constructore, and
deleting it only once in the destructor (thanks to Cory Fields for the
idea).

Replaces the fix by Jonas Schnelli in #7610, see discussion there.

Gregory Maxwell f28a87b4ba Decide eviction group ties based on time.
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.

Gregory Maxwell 35db253fb6 Do not absolutely protect local peers from eviction.
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.

Wladimir J. van der Laan 975dc649af torcontrol improvements and fixes
- 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

Wladimir J. van der Laan eb5f63fe58 net: Automatically create hidden service, listen on Tor
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.

Wladimir J. van der Laan 7c2ab05969 bitcoin-cli: Make error message less confusing
Sorry for the churn on this, but the current message (introduced in #9073)
isn't acceptable:

    $ src/bitcoin-cli getinfo
    rpc: couldn't connect to server
    (make sure server is running and you are connecting to the correct RPC port: -1 unknown)

Putting the error code after the words "RPC port" made me wonder whether
there was a port configuration issue.

This changes it to:

    $ src/bitcoin-cli getinfo
    error: couldn't connect to server: unknown (code -1)
    (make sure server is running and you are connecting to the correct RPC port)

Wladimir J. van der Laan 89bccddcd8 rpc: Split option -rpctimeout into -rpcservertimeout and -rpcclienttimeout
The two timeouts for the server and client, are essentially different:

- In the case of the server it should be a lower value to avoid clients
clogging up connection slots

- In the case of the client it should be a high value to accomedate slow
  responses from the server, for example for slow queries or when the
  lock is contended

Split the options into `-rpcservertimeout` and `-rpcclienttimeout` with
respective defaults of 30 and 900.
