4cba2fdafa483cbdb70f581174138ec253c80d48 util: extract {Read,Write}BinaryFile() to its own files (Vasil Dimov)
Pull request description:
Add I2P support by using the [I2P SAM](https://geti2p.net/en/docs/api/samv3) protocol. Unlike Tor, for incoming connections we get the I2P address of the peer (and they also receive ours when we are the connection initiator).
Two new options are added:
```
-i2psam=<ip:port>
I2P SAM proxy to reach I2P peers and accept I2P connections (default:
none)
-i2pacceptincoming
If set and -i2psam is also set then incoming I2P connections are
accepted via the SAM proxy. If this is not set but -i2psam is set
then only outgoing connections will be made to the I2P network.
Ignored if -i2psam is not set. Notice that listening for incoming
I2P connections is done through the SAM proxy, not by binding to
a local address and port (default: true)
```
# Overview of the changes
## Make `ReadBinary()` and `WriteBinary()` reusable
We would need to dump the I2P private key to a file and read it back later. Move those two functions out of `torcontrol.cpp`.
```
util: extract {Read,Write}BinaryFile() to its own files
util: fix ReadBinaryFile() returning partial contents
util: fix WriteBinaryFile() claiming success even if error occurred
```
## Split `CConnman::AcceptConnection()`
Most of `CConnman::AcceptConnection()` is agnostic of how the socket was accepted. The other part of it deals with the details of the `accept(2)` system call. Split those so that the protocol-agnostic part can be reused if we accept a socket by other means.
```
net: check for invalid socket earlier in CConnman::AcceptConnection()
net: get the bind address earlier in CConnman::AcceptConnection()
net: isolate the protocol-agnostic part of CConnman::AcceptConnection()
net: avoid unnecessary GetBindAddress() call
```
## Implement the I2P [SAM](https://geti2p.net/en/docs/api/samv3) protocol (not all of it)
Just the parts that would enable us to make outgoing and accept incoming I2P connections.
```
net: extend CNetAddr::SetSpecial() to support I2P
net: move the constant maxWait out of InterruptibleRecv()
net: dedup MSG_NOSIGNAL and MSG_DONTWAIT definitions
net: extend Sock::Wait() to report a timeout
net: extend Sock with methods for robust send & read until terminator
net: extend Sock with a method to check whether connected
net: implement the necessary parts of the I2P SAM protocol
```
## Use I2P SAM to connect to and accept connections from I2P peers
Profit from all of the preceding commits.
```
init: introduce I2P connectivity options
net: add I2P to the reachability map
net: make outgoing I2P connections from CConnman
net: accept incoming I2P connections from CConnman
net: recognize I2P from ParseNetwork() so that -onlynet=i2p works
net: Do not skip the I2P network from GetNetworkNames()
```

e3e0a2432c587ee06e469c37ffae133b7ac55c77 Add benchmark to write JSON into a string (Martin Ankerl)
Pull request description:
The benchmark `BlockToJsonVerbose` only tests generating (and destroying)
the JSON data structure, but serializing into a string is also a
performance critical aspect of the RPC calls.
Extracts test setup into a `struct TestBlockAndIndex`, and uses it in
both `BlockToJsonVerbose` and `BlockToJsonVerboseWrite`.
Also, use `ankerl::nanobench::doNotOptimizeAway` to make sure the compiler
can't optimize the result of the calls away.
Here are benchmark results on my Intel i7-8700:

So that help texts include "i2p" in:
* `./bitcoind -help` (in `-onlynet` description)
* `getpeerinfo` RPC
* `getnetworkinfo` RPC
Co-authored-by: Jon Atack <jon@atack.com>
|

|
|
|
|
|
|
Update `CNetAddr::GetReachabilityFrom()` to recognize the I2P network so
that we would prefer to advertise our I2P address to I2P peers.
|
|
Introduce two new options to reach the I2P network:
* `-i2psam=<ip:port>` point to the I2P SAM proxy. If this is set then
the I2P network is considered reachable and we can make outgoing
connections to I2P peers via that proxy. We listen for and accept
incoming connections from I2P peers if the below is set in addition to
`-i2psam=<ip:port>`
* `-i2pacceptincoming` if this is set together with `-i2psam=<ip:port>`
then we accept incoming I2P connections via the I2P SAM proxy.
|
|
Implement the following commands from the I2P SAM protocol:
* HELLO: needed for all of the remaining ones
* DEST GENERATE: to generate our private key and destination
* NAMING LOOKUP: to convert .i2p addresses to destinations
* SESSION CREATE: needed for STREAM CONNECT and STREAM ACCEPT
* STREAM CONNECT: to make outgoing connections
* STREAM ACCEPT: to accept incoming connections
|
|
This will be convenient in the I2P SAM implementation.
|
|
Introduce two high level, convenience methods in the `Sock` class:
* `SendComplete()`: keep trying to send the specified data until either
successfully sent all of it, timeout or interrupted.
* `RecvUntilTerminator()`: read until a terminator is encountered (never
after it), timeout or interrupted.
These will be convenient in the I2P SAM implementation.
`SendComplete()` can also be used in the SOCKS5 implementation instead
of calling `send()` directly.
|
|
Previously `Sock::Wait()` would not have signaled to the caller whether
a timeout or one of the requested events occurred since that was not
needed by any of the callers.
Such functionality will be needed in the I2P implementation, thus extend
the `Sock::Wait()` method.
|
|
Deduplicate `MSG_NOSIGNAL` and `MSG_DONTWAIT` definitions from `net.cpp`
and `netbase.cpp` to `compat.h` where they can also be reused by other
code.
|
|
Move `maxWait` out of `InterruptibleRecv()` and rename it to
`MAX_WAIT_FOR_IO` so that it can be reused by other code.
|
|
Recognize also I2P addresses in the form `base32hashofpublickey.b32.i2p`
from `CNetAddr::SetSpecial()`.
This makes `Lookup()` support them, which in turn makes it possible to
manually connect to an I2P node by using
`-proxy=i2p_socks5_proxy:port -addnode=i2p_address.b32.i2p:port`
Co-authored-by: Lucas Ontivero <lucasontivero@gmail.com>

|
Our local (bind) address is already saved in `CNode::addrBind` and there
is no need to re-retrieve it again with `GetBindAddress()`.
Also, for I2P connections `CNode::addrBind` would contain our I2P
address, but `GetBindAddress()` would return something like
`127.0.0.1:RANDOM_PORT`.
|
|
Isolate the second half of `CConnman::AcceptConnection()` into a new
separate method, which could be reused if we accept incoming connections
by other means than `accept()` (first half of
`CConnman::AcceptConnection()`).
|
|
Call `GetBindAddress()` earlier in `CConnman::AcceptConnection()`. That
is specific to the TCP protocol and makes the code below it reusable for
other protocols, if the caller provides `addr_bind`, retrieved by other
means.
|
|
This check is related to an `accept()` failure. So do the check earlier,
closer to the `accept()` call.
This will allow to isolate the `accept()`-specific code at the beginning
of `CConnman::AcceptConnection()` and reuse the code that follows it.
|
|
`fclose()` is flushing any buffered data to disk, so if it fails then
that could mean that the data was not completely written to disk.
Thus, check if `fclose()` succeeds and only then claim success from
`WriteBinaryFile()`.
|
|
If an error occurs and `fread()` returns `0` (nothing was read) then the
code before this patch would have returned "success" with a partially
read contents of the file.
|
|
Extract `ReadBinaryFile()` and `WriteBinaryFile()` from `torcontrol.cpp`
to its own `readwritefile.{h,cpp}` files, so that it can be reused from
other modules.

{sign,verify}message RPCs

e62f0c71f10def124b1c1219d790cef246a32c3e rpc: fix {sign,message}verify RPC errors for invalid address/signature (Sebastian Falbesoner)
Pull request description:
RPCs that accept address parameters usually return the intended error code `RPC_INVALID_ADDRESS_OR_KEY` (-5) if a passed address is invalid. The two exceptions to the rule are `signmessage` and `verifymessage`, which return `RPC_TYPE_ERROR` (-3) in this case instead. Oddly enough `verifymessage` returns `RPC_INVALID_ADDRESS_OR_KEY` when the _signature_ was malformed, where `RPC_TYPE_ERROR` would be more approriate.
This PR fixes these inaccuracies and as well adds tests to `rpc_signmessage.py` that check the parameter validity and error codes for the related RPCs `signmessagewithprivkey`, `signmessage` and `verifymessage`.

Pull request description:
This reverts PR #211.
I disagree with this change, I use the functionality a lot, it was the primary way I used to organize and edit transactions labels and am sad to see this go.
> you can edit a sending address in the send tab Address Book
Using the address book should not be encouraged at all! A while ago it was even proposed to remove it. There's rarely need to scroll through all historical addresses used and unused. The transaction list does just fine for this.
> While all other actions apply directly to the selected transaction, the Edit Label action applies to the selected transaction's address.
**In practice** when bitcoin is used in the commonly advised way, generate a new address for each transaction, those are equivalent though.
I doubt I (and **luke-jr**) will be the only users that will stumblle on this. Further discussion here: https://github.com/bitcoin-core/gui/pull/211#issuecomment-784755998

Pull request description:
The recent requests table will allow you to copy data points even if they do not exist. This PR implements checks to disable the `copy label`, `copy message`, and `copy amount` context menu actions if the respective fields are empty. This brings the recent requests table context menu behavior closer to the behavior seen in the transaction view.
On a payment request entry which does not have a value for label, message, or amount:

`copy URI` never needs to be disabled as an entry in the recent requests table must have a URI even if it doesn't have a label, message, or amount. #213 will add a `copy address` context menu action. This also does not need a check as an entry must be associated with an address.

Pull request description:
https://github.com/bitcoin/bitcoin/issues/11168 is not fixed by https://github.com/bitcoin/bitcoin/pull/11169 completely, as users are allowed to right click on the menu bar:
This PR moves the context menu prohibition from `QToolBar` instance to its parent `BitcoinGUI` instance, which is derived from `QMainWindow`.

fd6580e405699ccb051fd2a34525e48d3253673d [refactor] txmempool: split epoch logic into class (Anthony Towns)
Pull request description:
Splits the epoch logic introduced in #17925 into a separate class.
Uses clang's thread safety annotations and encapsulates the data more strongly to reduce chances of bugs from API misuse.

jonatack:
ACK fd6580e405699ccb051fd2a34525e48d3253673d using clang thread safety annotations looks like a very good idea, and the encapsulation this change adds should improve robustness (and possible unit test-ability) of the code. Verified that changing some of the locking duly provoked build-time warnings with Clang 9 on Debian and that small changes in the new `Epoch` class were covered by failing functional test assertions in `mempool_updatefromblock.py`, `mempool_resurrect.py`, and `mempool_reorg.py`

9bac71350d98580cc7441957fc7c3fa2f4158553 build: make HAVE_O_CLOEXEC available outside LevelDB (bugfix) (Sebastian Falbesoner)
584fd91d2d294883e6896dbd64a2176528e94581 init: only use pipe2 if availabile, check in configure (Sebastian Falbesoner)
Pull request description:
The result of the O_CLOEXEC availability check is currently only set in the Makefile and passed to LevelDB (see `LEVELDB_CPPFLAGS_INT` in `src/Makefile.leveldb.include`), but not defined to be used in our codebase. This means that code within the preprocessor conditional `#if HAVE_O_CLOEXEC` was actually never compiled. On the master branch this is currently used for pipe creation in `src/shutdown.cpp`, PR #21007 moves this part to a new module (I found the issue while testing that PR).
The fix is similar to the one in #19803, which solved the same problem for HAVE_FDATASYNC.
In the course of working on the PR it turned out that pipe2 is not available an all platforms, hence a configure check and a corresponding define HAVE_PIPE2 is introduced and used.
The PR can be tested by anyone with a system that has pipe2 and O_CLOEXEC available by putting gibberish into the HAVE_O_CLOEXEC block: on master, everything should compile fine, on PR, the compiler should abort with an error. At least that's my naive way of testing preprocessor logic, happy to hear more sophisticated ways :-)

Pull request description:
Big picture overview in [this gist](https://gist.github.com/Sjors/29d06728c685e6182828c1ce9b74483d).
This PR lets `bitcoind` call an arbitrary command `-signer=<cmd>`, e.g. a hardware wallet driver, where it can fetch public keys, ask to display an address, and sign a transaction (using PSBT under the hood).
It's design to work with https://github.com/bitcoin-core/HWI, which supports multiple hardware wallets. Any command with the same arguments and return values will work. It simplifies the manual procedure described [here](https://github.com/bitcoin-core/HWI/blob/master/docs/bitcoin-core-usage.md).
Usage is documented in [doc/external-signer.md](
https://github.com/Sjors/bitcoin/blob/2019/08/hww-box2/doc/external-signer.md), which also describes what protocol a different signer binary should conform to.
Use `--enable-external-signer` to opt in, requires Boost::Process:
```
Options used to compile and link:
with wallet = yes
with gui / qt = no
external signer = yes
```
It adds the following RPC methods:
* `enumeratesigners`: asks <cmd> for a list of signers (e.g. devices) and their master key fingerprint
* `signerdisplayaddress <address>`: asks <cmd> to display an address
It enhances the following RPC methods:
* `createwallet`: takes an additional `external_signer` argument and fetches keys from device
* `send`: automatically sends transaction to device and waits
Usage TL&DR:
* clone HWI repo somewhere and launch `bitcoind -signer=../HWI/hwi.py`
* check if you can see your hardware device: `bitcoin-cli enumeratesigners`
* create wallet and auto import keys `bitcoin-cli createwallet "hww" true true "" true true true`
* display address on device: `bitcoin-cli signerdisplayaddress ...`
* to spend, use `send` RPC and approve transaction on device
Prerequisites:
- [x] #21127 load wallet flags before everything else
- [x] #21182 remove mostly pointless BOOST_PROCESS macro
Potentially useful followups:
- GUI support: bitcoin-core/gui#4
- bumpfee support
- (automatically) verify (a subset of) keys on the device after import, through message signing
