The dhcp server is systemd-networkd, and the dhcp plugin can request an ip but can not renew it. The systemd-networkd just ignore the renew request. ``` 2024/09/14 21:46:00 no DHCP packet received within 10s 2024/09/14 21:46:00 retrying in 31.529038 seconds 2024/09/14 21:46:42 no DHCP packet received within 10s 2024/09/14 21:46:42 retrying in 63.150490 seconds 2024/09/14 21:47:45 98184616c91f15419f5cacd012697f85afaa2daeb5d3233e28b0ec21589fb45a/iot/eth1: no more tries 2024/09/14 21:47:45 98184616c91f15419f5cacd012697f85afaa2daeb5d3233e28b0ec21589fb45a/iot/eth1: renewal time expired, rebinding 2024/09/14 21:47:45 Link "eth1" down.

# CHANGELOG
|
|
|
|
## v0.5.1
|
|
|
|
- [Improvement]: revert `go.mod` to Go 1.20 to [resolve an issue around Go
|
|
module version upgrades](https://github.com/mdlayher/socket/issues/13).
|
|
|
|
## v0.5.0
|
|
|
|
**This is the first release of package socket that only supports Go 1.21+.
|
|
Users on older versions of Go must use v0.4.1.**
|
|
|
|
- [Improvement]: drop support for older versions of Go.
|
|
- [New API]: add `socket.Conn` wrappers for various `Getsockopt` and
|
|
`Setsockopt` system calls.
|
|
|
|
## 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).
