58ef0ff doc: update docs for Tor listening (Wladimir J. van der Laan)
68ccdc4 doc: Mention Tor listening in release notes (Wladimir J. van der Laan)
09c1ae1 torcontrol improvements and fixes (Wladimir J. van der Laan)
2f796e5 Better error message if Tor version too old (Peter Todd)
8f4e67f net: Automatically create hidden service, listen on Tor (Wladimir J. van der Laan)
- 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

Previous text could be interpreted as the the _additional_ fee paid by
the result on top of the fee the original version paid, rather than the
correct interpretation: the absolute fee the resulting tx pays.
Previously all conflicting transactions were evaluated as a whole to
determine if the feerate was being increased. This meant that low
feerate children pulled the feerate down, potentially allowing a high
transaction with a high feerate to be replaced by one with a lower
feerate.
Replaces transactions already in the mempool if a new transaction seen
with a higher fee, specifically both a higher fee per KB and a higher
absolute fee. Children are evaluateed for replacement as well, using the
mempool package tracking to calculate replaced fees/size. Transactions
can opt-out of transaction replacement by setting nSequence >= maxint-1
on all inputs. (which all wallets do already)
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.
Process `getheaders` messages from whitelisted peers even if we are in
initial block download. Whitelisted peers can always use a node as a
block source.
Also log a debug message when the request is ignored, for
troubleshooting.
Fixes#6971.

Previously, the undo weren't being flushed during a reindex because
fKnown was set to true in FindBlockPos. That is the correct behaviour
for block files as they aren't being touched, but undo files are
touched.
This changes the behaviour to always flush when switching to a new file
(even for block files, though that isn't really necessary).
The docs talk about bits 2 and 4 instead of 2 and 3, and bits are being
indexed from both 1 (describing nCode) and 0 (in second example).
Changed to use zero-indexing for all.
