# CHANGELOG
|
|
|
|
## Unreleased
|
|
|
|
## v1.6.0
|
|
|
|
**This is the first release of package netlink that only supports Go 1.13+.
|
|
Users on older versions of Go must use v1.5.0.**
|
|
|
|
- [New API] [commit](https://github.com/mdlayher/netlink/commit/ad9e2c41caa993e3f4b68831d6cb2cb05818275d):
|
|
the `netlink.Config.Strict` field can be used to apply a more strict default
|
|
set of options to a `netlink.Conn`. This is recommended for applications
|
|
running on modern Linux kernels, but cannot be enabled by default because the
|
|
options may require a more recent kernel than the minimum kernel version that
|
|
Go supports. See the documentation for details.
|
|
- [Improvement]: broke some integration tests into a separate Go module so the
|
|
default `go.mod` for package `netlink` has fewer dependencies.
|
|
|
|
## v1.5.0
|
|
|
|
**This is the last release of package netlink that supports Go 1.12.**
|
|
|
|
- [New API] [commit](https://github.com/mdlayher/netlink/commit/53a1c10065e51077659ceedf921c8f0807abe8c0):
|
|
the `netlink.Config.PID` field can be used to specify an explicit port ID when
|
|
binding the netlink socket. This is intended for advanced use cases and most
|
|
callers should leave this field set to 0.
|
|
- [Improvement]: more low-level functionality ported to
|
|
`github.com/mdlayher/socket`, reducing package complexity.
|
|
|
|
## v1.4.2
|
|
|
|
- [Documentation] [commit](https://github.com/mdlayher/netlink/commit/177e6364fb170d465d681c7c8a6283417a6d3e49):
|
|
the `netlink.Config.DisableNSLockThread` now properly uses Go's deprecated
|
|
identifier convention. This option has been a noop for a long time and should
|
|
not be used.
|
|
- [Improvement] [#189](https://github.com/mdlayher/netlink/pull/189): the
|
|
package now uses Go 1.17's `//go:build` identifiers. Thanks @tklauser.
|
|
- [Bug Fix]
|
|
[commit](https://github.com/mdlayher/netlink/commit/fe6002e030928bd1f2a446c0b6c65e8f2df4ed5e):
|
|
the `netlink.AttributeEncoder`'s `Bytes`, `String`, and `Do` methods now
|
|
properly reject byte slices and strings which are too large to fit in the
|
|
value of a netlink attribute. Thanks @ubiquitousbyte for the report.
|
|
|
|
## v1.4.1
|
|
|
|
- [Improvement]: significant runtime network poller integration cleanup through
|
|
the use of `github.com/mdlayher/socket`.
|
|
|
|
## v1.4.0
|
|
|
|
- [New API] [#185](https://github.com/mdlayher/netlink/pull/185): the
|
|
`netlink.AttributeDecoder` and `netlink.AttributeEncoder` types now have
|
|
methods for dealing with signed integers: `Int8`, `Int16`, `Int32`, and
|
|
`Int64`. These are necessary for working with rtnetlink's XDP APIs. Thanks
|
|
@fbegyn.
|
|
|
|
## v1.3.2
|
|
|
|
- [Improvement]
|
|
[commit](https://github.com/mdlayher/netlink/commit/ebc6e2e28bcf1a0671411288423d8116ff924d6d):
|
|
`github.com/google/go-cmp` is no longer a (non-test) dependency of this module.
|
|
|
|
## v1.3.1
|
|
|
|
- [Improvement]: many internal cleanups and simplifications. The library is now
|
|
slimmer and features less internal indirection. There are no user-facing
|
|
changes in this release.
|
|
|
|
## v1.3.0
|
|
|
|
- [New API] [#176](https://github.com/mdlayher/netlink/pull/176):
|
|
`netlink.OpError` now has `Message` and `Offset` fields which are populated
|
|
when the kernel returns netlink extended acknowledgement data along with an
|
|
error code. The caller can turn on this option by using
|
|
`netlink.Conn.SetOption(netlink.ExtendedAcknowledge, true)`.
|
|
- [New API]
|
|
[commit](https://github.com/mdlayher/netlink/commit/beba85e0372133b6d57221191d2c557727cd1499):
|
|
the `netlink.GetStrictCheck` option can be used to tell the kernel to be more
|
|
strict when parsing requests. This enables more safety checks and can allow
|
|
the kernel to perform more advanced request filtering in subsystems such as
|
|
route netlink.
|
|
|
|
## v1.2.1
|
|
|
|
- [Bug Fix]
|
|
[commit](https://github.com/mdlayher/netlink/commit/d81418f81b0bfa2465f33790a85624c63d6afe3d):
|
|
`netlink.SetBPF` will no longer panic if an empty BPF filter is set.
|
|
- [Improvement]
|
|
[commit](https://github.com/mdlayher/netlink/commit/8014f9a7dbf4fd7b84a1783dd7b470db9113ff36):
|
|
the library now uses https://github.com/josharian/native to provide the
|
|
system's native endianness at compile time, rather than re-computing it many
|
|
times at runtime.
|
|
|
|
## v1.2.0
|
|
|
|
**This is the first release of package netlink that only supports Go 1.12+.
|
|
Users on older versions of Go must use v1.1.1.**
|
|
|
|
- [Improvement] [#173](https://github.com/mdlayher/netlink/pull/173): support
|
|
for Go 1.11 and below has been dropped. All users are highly recommended to
|
|
use a stable and supported release of Go for their applications.
|
|
- [Performance] [#171](https://github.com/mdlayher/netlink/pull/171):
|
|
`netlink.Conn` no longer requires a locked OS thread for the vast majority of
|
|
operations, which should result in a significant speedup for highly concurrent
|
|
callers. Thanks @ti-mo.
|
|
- [Bug Fix] [#169](https://github.com/mdlayher/netlink/pull/169): calls to
|
|
`netlink.Conn.Close` are now able to unblock concurrent calls to
|
|
`netlink.Conn.Receive` and other blocking operations.
|
|
|
|
## v1.1.1
|
|
|
|
**This is the last release of package netlink that supports Go 1.11.**
|
|
|
|
- [Improvement] [#165](https://github.com/mdlayher/netlink/pull/165):
|
|
`netlink.Conn` `SetReadBuffer` and `SetWriteBuffer` methods now attempt the
|
|
`SO_*BUFFORCE` socket options to possibly ignore system limits given elevated
|
|
caller permissions. Thanks @MarkusBauer.
|
|
- [Note]
|
|
[commit](https://github.com/mdlayher/netlink/commit/c5f8ab79aa345dcfcf7f14d746659ca1b80a0ecc):
|
|
`netlink.Conn.Close` has had a long-standing bug
|
|
[#162](https://github.com/mdlayher/netlink/pull/162) related to internal
|
|
concurrency handling where a call to `Close` is not sufficient to unblock
|
|
pending reads. To effectively fix this issue, it is necessary to drop support
|
|
for Go 1.11 and below. This will be fixed in a future release, but a
|
|
workaround is noted in the method documentation as of now.
|
|
|
|
## v1.1.0
|
|
|
|
- [New API] [#157](https://github.com/mdlayher/netlink/pull/157): the
|
|
`netlink.AttributeDecoder.TypeFlags` method enables retrieval of the type bits
|
|
stored in a netlink attribute's type field, because the existing `Type` method
|
|
masks away these bits. Thanks @ti-mo!
|
|
- [Performance] [#157](https://github.com/mdlayher/netlink/pull/157): `netlink.AttributeDecoder`
|
|
now decodes netlink attributes on demand, enabling callers who only need a
|
|
limited number of attributes to exit early from decoding loops. Thanks @ti-mo!
|
|
- [Improvement] [#161](https://github.com/mdlayher/netlink/pull/161): `netlink.Conn`
|
|
system calls are now ready for Go 1.14+'s changes to goroutine preemption.
|
|
See the PR for details.
|
|
|
|
## v1.0.0
|
|
|
|
- Initial stable commit.
