This includes two new hidden commands: a 9p server, `podman machine server9p`, and a 9p client, `podman machine client9p` with `server9p` currently only configured to run on Windows and serve 9p via HyperV vsock, and `client9p` only configured to run on Linux. The server is run by `podman machine start` and has the same lifespan as gvproxy (waits for the gvproxy PID to die before shutting down). The client is run inside the VM, also by `podman machine start`, and mounts uses kernel 9p mount code to complete the mount. It's unfortunately not possible to use mount directly without the wrapper; we need to set up the vsock and pass it to mount as an FD. In theory this can be generalized so that the server can run anywhere and over almost any transport, but I haven't done this here as I don't think we have a usecase other than HyperV right now. [NO NEW TESTS NEEDED] This requires changes to Podman in the VM, so we need to wait until a build with this lands in FCOS to test. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

# CHANGELOG
|
|
|
|
## v0.4.1
|
|
|
|
- [Bug Fix] [commit](https://github.com/mdlayher/socket/commit/2a14ceef4da279de1f957c5761fffcc6c87bbd3b):
|
|
ensure `socket.Conn` can be used with non-socket file descriptors by handling
|
|
`ENOTSOCK` in the constructor.
|
|
|
|
## v0.4.0
|
|
|
|
**This is the first release of package socket that only supports Go 1.18+.
|
|
Users on older versions of Go must use v0.3.0.**
|
|
|
|
- [Improvement]: drop support for older versions of Go so we can begin using
|
|
modern versions of `x/sys` and other dependencies.
|
|
|
|
## v0.3.0
|
|
|
|
**This is the last release of package socket that supports Go 1.17 and below.**
|
|
|
|
- [New API/API change] [PR](https://github.com/mdlayher/socket/pull/8):
|
|
numerous `socket.Conn` methods now support context cancelation. Future
|
|
releases will continue adding support as needed.
|
|
- New `ReadContext` and `WriteContext` methods.
|
|
- `Connect`, `Recvfrom`, `Recvmsg`, `Sendmsg`, and `Sendto` methods now accept
|
|
a context.
|
|
- `Sendto` parameter order was also fixed to match the underlying syscall.
|
|
|
|
## v0.2.3
|
|
|
|
- [New API] [commit](https://github.com/mdlayher/socket/commit/a425d96e0f772c053164f8ce4c9c825380a98086):
|
|
`socket.Conn` has new `Pidfd*` methods for wrapping the `pidfd_*(2)` family of
|
|
system calls.
|
|
|
|
## v0.2.2
|
|
|
|
- [New API] [commit](https://github.com/mdlayher/socket/commit/a2429f1dfe8ec2586df5a09f50ead865276cd027):
|
|
`socket.Conn` has new `IoctlKCM*` methods for wrapping `ioctl(2)` for `AF_KCM`
|
|
operations.
|
|
|
|
## v0.2.1
|
|
|
|
- [New API] [commit](https://github.com/mdlayher/socket/commit/b18ddbe9caa0e34552b4409a3aa311cb460d2f99):
|
|
`socket.Conn` has a new `SetsockoptPacketMreq` method for wrapping
|
|
`setsockopt(2)` for `AF_PACKET` socket options.
|
|
|
|
## v0.2.0
|
|
|
|
- [New API] [commit](https://github.com/mdlayher/socket/commit/6e912a68523c45e5fd899239f4b46c402dd856da):
|
|
`socket.FileConn` can be used to create a `socket.Conn` from an existing
|
|
`os.File`, which may be provided by systemd socket activation or another
|
|
external mechanism.
|
|
- [API change] [commit](https://github.com/mdlayher/socket/commit/66d61f565188c23fe02b24099ddc856d538bf1a7):
|
|
`socket.Conn.Connect` now returns the `unix.Sockaddr` value provided by
|
|
`getpeername(2)`, since we have to invoke that system call anyway to verify
|
|
that a connection to a remote peer was successfully established.
|
|
- [Bug Fix] [commit](https://github.com/mdlayher/socket/commit/b60b2dbe0ac3caff2338446a150083bde8c5c19c):
|
|
check the correct error from `unix.GetsockoptInt` in the `socket.Conn.Connect`
|
|
method. Thanks @vcabbage!
|
|
|
|
## v0.1.2
|
|
|
|
- [Bug Fix]: `socket.Conn.Connect` now properly checks the `SO_ERROR` socket
|
|
option value after calling `connect(2)` to verify whether or not a connection
|
|
could successfully be established. This means that `Connect` should now report
|
|
an error for an `AF_INET` TCP connection refused or `AF_VSOCK` connection
|
|
reset by peer.
|
|
- [New API]: add `socket.Conn.Getpeername` for use in `Connect`, but also for
|
|
use by external callers.
|
|
|
|
## v0.1.1
|
|
|
|
- [New API]: `socket.Conn` now has `CloseRead`, `CloseWrite`, and `Shutdown`
|
|
methods.
|
|
- [Improvement]: internal rework to more robustly handle various errors.
|
|
|
|
## v0.1.0
|
|
|
|
- Initial unstable release. Most functionality has been developed and ported
|
|
from package [`netlink`](https://github.com/mdlayher/netlink).
