2023-11-07Merge bitcoin/bitcoin#28649: Do the SOCKS5 handshake reliablyAndrew Chow
af0fca530e4d8311bcb24a14c416e5ad7c30ff78 netbase: use reliable send() during SOCKS5 handshake (Vasil Dimov) 1b19d1117ca5373a15313227b547ef4392022dbd sock: change Sock::SendComplete() to take Span (Vasil Dimov) Pull request description: The `Socks5()` function which does the SOCKS5 handshake with the SOCKS5 proxy sends bytes to the socket without retrying partial writes. `send(2)` may write only part of the provided data and return. In this case the caller is responsible for retrying the operation with the remaining data. Change `Socks5()` to do that. There is already a method `Sock::SendComplete()` which does exactly that, so use it in `Socks5()`. A minor complication for this PR is that `Sock::SendComplete()` takes `std::string` argument whereas `Socks5()` has `std::vector<uint8_t>`. Thus the necessity for the first commit. It is possible to do also in other ways - convert the data in `Socks5()` to `std::string` or have just one `Sock::SendComplete()` that takes `void*` and change the callers to pass `str.data(), str.size()` or `vec.data(), vec.size()`. This came up while testing https://github.com/bitcoin/bitcoin/pull/27375.

2023-10-31netbase: use reliable send() during SOCKS5 handshakeVasil Dimov
`send(2)` can be interrupted or for another reason it may not fully complete sending all the bytes. We should be ready to retry the send with the remaining bytes. This is what `Sock::SendComplete()` does, thus use it in `Socks5()`. Since `Sock::SendComplete()` takes a `CThreadInterrupt` argument, change also the recv part of `Socks5()` to use `CThreadInterrupt` instead of a boolean. Easier reviewed with `git show -b` (ignore white-space changes).

2023-10-16netbase: possibly change the result of LookupSubNet() to CJDNSVasil Dimov
All callers of `LookupSubNet()` need the result to be of CJDNS type if `-cjdnsreachable` is set and the address begins with `fc`: * `NetWhitelistPermissions::TryParse()`: otherwise `-whitelist=` fails to white list CJDNS addresses: when a CJDNS peer connects to us, it will be matched against IPv6 `fc...` subnet and the match will never succeed. * `BanMapFromJson()`: CJDNS bans are stored as just IPv6 addresses in `banlist.json`. Upon reading from disk they have to be converted back to CJDNS, otherwise, after restart, a ban entry like (`fc00::1`, IPv6) would not match a peer (`fc00::1`, CJDNS). * `setban()` (in `rpc/net.cpp`): otherwise `setban fc.../mask add` would add an IPv6 entry to BanMan. Subnetting does not make sense for CJDNS addresses, thus treat `fc.../mask` as invalid `CSubNet`. The result of `LookupHost()` has to be converted for the case of banning a single host. * `InitHTTPAllowList()`: not necessary since before this change `-rpcallowip=fc...` would match IPv6 subnets against IPv6 peers even if they started with `fc`. But because it is necessary for the above, `HTTPRequest::GetPeer()` also has to be adjusted to return CJDNS peer, so that now CJDNS peers are matched against CJDNS subnets.
2023-10-05net: move MaybeFlipIPv6toCJDNS() from net to netbaseVasil Dimov
It need not be in the `net` module and we need to call it from `LookupSubNet()`, thus move it to `netbase`.
2023-10-05net: move IsReachable() code to netbase and encapsulate itVasil Dimov
`vfLimited`, `IsReachable()`, `SetReachable()` need not be in the `net` module. Move them to `netbase` because they will be needed in `LookupSubNet()` to possibly flip the result to CJDNS (if that network is reachable). In the process, encapsulate them in a class. `NET_UNROUTABLE` and `NET_INTERNAL` are no longer ignored when adding or removing reachable networks. This was unnecessary.

The socket is always valid (the underlying file descriptor is not `INVALID_SOCKET`) when `ConnectSocketDirectly()` is called.

error is a low-level function with a sole dependency on LogPrintf, which is defined in logging.h The background of this commit is an ongoing effort to decouple the libbitcoinkernel library from the ArgsManager defined in system.h. Moving the function out of system.h allows including it from a separate source file without including the ArgsManager definitions from system.h.

2022-12-12net: remove CService::ToString() use ToStringAddrPort() insteadVasil Dimov
Both methods do the same thing, so simplify to having just one. `ToString()` is too generic in this case and it is unclear what it does, given that there are similar methods: `ToStringAddr()` (inherited from `CNetAddr`), `ToStringPort()` and `ToStringAddrPort()`.

2021-03-16net: change ConnectSocketDirectly() to take a Sock argumentVasil Dimov
Change `ConnectSocketDirectly()` to take a `Sock` argument instead of a bare `SOCKET`. With this, use the `Sock`'s (possibly mocked) methods `Connect()`, `Wait()` and `GetSockOpt()` instead of calling the OS functions directly.
