23333b7ed243071c9b4e4f04c727556d8065acbb net: Allow DNS lookups on nodes with IPV6 lo only (Max Edwards) Pull request description: This is similar to (but does not fix) https://github.com/bitcoin/bitcoin/issues/13155 which I believe is the same issue but in libevent. The issue is on a host that has IPV6 enabled but only a loopback IP address `-proxy=[::1]` will fail as `[::1]` is not considered valid by `getaddrinfo` with `AI_ADDRCONFIG` flag. I think the loopback interface should be considered valid and we have a functional test that will try to test this: `feature_proxy.py`. To replicate the issue, run `feature_proxy.py` inside a docker container that has IPV6 loopback ::1 address without specifically giving that container an external IPV6 address. This should be the default with recent versions of docker. IPV6 on loopback interface was enabled in docker engine 26 and later ([https://docs.docker.com/engine/release-notes/26.0/#bug-fixes-and-enhancements-2](https://docs.docker.com/engine/release-notes/26.0/#bug-fixes-and-enhancements-2)). `AI_ADDRCONFIG` was introduced to prevent slow DNS lookups on systems that were IPV4 only. References: Man section on `AI_ADDRCONFIG`: ``` If hints.ai_flags includes the AI_ADDRCONFIG flag, then IPv4 addresses are returned in the list pointed to by res only if the local system has at least one IPv4 address configured, and IPv6 addresses are returned only if the local system has at least one IPv6 address configured. The loopback address is not considered for this case as valid as a configured address. This flag is useful on, for ex‐ ample, IPv4-only systems, to ensure that getaddrinfo() does not return IPv6 socket addresses that would always fail in connect(2) or bind(2). ``` [AI_ADDRCONFIG considered harmful Wiki entry by Fedora](https://fedoraproject.org/wiki/QA/Networking/NameResolution/ADDRCONFIG) [Mozilla discussing slow DNS without AI_ADDRCONFIG and also localhost issues with it](https://bugzilla.mozilla.org/show_bug.cgi?id=467497) ACKs for top commit: achow101: ACK 23333b7ed243071c9b4e4f04c727556d8065acbb tdb3: ACK 23333b7ed243071c9b4e4f04c727556d8065acbb pinheadmz: ACK 23333b7ed243071c9b4e4f04c727556d8065acbb Tree-SHA512: 5ecd8c72d1e1c28e3ebff07346381d74eaddef98dca830f6d3dbf098380562fa68847d053c0d84cc8ed19a45148ceb5fb244e4820cf63dccb10ab3db53175020
2024-07-13net: Allow DNS lookups on nodes with IPV6 lo onlyMax Edwards
AI_ADDRCONFIG prevents ::1 from being considered a valid address on hosts that have a IPV6 loopback IP address but no other IPV6 interfaces.

2024-06-14netbase: extend CreateSock() to support creating arbitrary socketsVasil Dimov
Allow the callers of `CreateSock()` to pass all 3 arguments to the `socket(2)` syscall. This makes it possible to create sockets of any domain/type/protocol.
2024-05-16util: Move util/string.h functions to util namespaceRyan Ofsky
There are no changes to behavior. Changes in this commit are all additions, and are easiest to review using "git diff -U0 --word-diff-regex=." options. Motivation for this change is to keep util functions with really generic names like "Split" and "Join" out of the global namespace so it is easier to see where these functions are defined, and so they don't interfere with function overloading, especially since the util library is a dependency of the kernel library and intended to be used with external code.

There has been work on [unix domain sockets before](https://github.com/bitcoin/bitcoin/pull/9979) but for now I just wanted to start on this single use-case which is enabling unix sockets from the client side, specifically connecting to a local Tor proxy (Tor can listen on unix sockets and even enforces strict curent-user-only access permission before binding) configured by `-onion=` or `-proxy=` I copied the prefix `unix:` usage from Tor.

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.

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()`.

Since the former is mockable, this makes it easier to test higher level code that sets the TCP_NODELAY flag.

c71117fcb04fc2e45b5e76fe96b077a07b0c0f82 net: remove non-blocking bool from interface (Bushstar) Pull request description: SetSocketNonBlocking was added in 0.11 in the PR below with a second argument to toggle non-blocking mode for the socket. That argument has always been set to true in all subsequent releases and I'm not sure why it is present. https://github.com/bitcoin/bitcoin/pull/4491 ACKs for top commit: promag: Code review ACK c71117fcb04fc2e45b5e76fe96b077a07b0c0f82. lsilva01: Code review ACK https://github.com/bitcoin/bitcoin/pull/22052/commits/c71117fcb04fc2e45b5e76fe96b077a07b0c0f82 vasild: ACK c71117fcb04fc2e45b5e76fe96b077a07b0c0f82 Tree-SHA512: feebfcfa75d997460a0ba42ffe1e0c25a7e0bfcad12510ad73ea4942cc1c653f9ad429adbbb00b9288fe319009552906fcb635a14dfd7dcbde3853baab6be065

Bitcoin Core has a strong preference for only connecting to nodes that listen on that port. Remove that preference because connections over clearnet that involve port 8333 make it easy to detect, analyze, block or divert Bitcoin p2p traffic before the connection is even established (at TCP SYN time).
