feat: add ability to listen on unix socket/named pipe
Add a -socket option that configures the server to listen on a Unix-domain socket or Windows named pipe instead of a TCP port. This allows webhook to be used behind a reverse proxy on multi-tenant shared hosting without the need to choose (and the permission to bind to) a free port number. On Windows, -socket is expected to be a named pipe such as \\.\pipe\webhook, and the code uses https://github.com/microsoft/go-winio to bind the listening socket. On other platforms, -socket is the path to a Unix domain socket such as /tmp/webhook.sock, or an abstract socket name starting with @, bound using the regular net.Listen function with the "network" parameter set to "unix". Note: this pushes our minimum Go version up to 1.21 as that is what go-winio requires, but that is already the minimum version against which we are testing in the CI matrix.

# go-winio [](https://github.com/microsoft/go-winio/actions/workflows/ci.yml)
|
||||
|
||||
This repository contains utilities for efficiently performing Win32 IO operations in
|
||||
Go. Currently, this is focused on accessing named pipes and other file handles, and
|
||||
for using named pipes as a net transport.
|
||||
|
||||
This code relies on IO completion ports to avoid blocking IO on system threads, allowing Go
|
||||
to reuse the thread to schedule another goroutine. This limits support to Windows Vista and
|
||||
newer operating systems. This is similar to the implementation of network sockets in Go's net
|
||||
package.
|
||||
|
||||
Please see the LICENSE file for licensing information.
|
||||
|
||||
## Contributing
|
||||
|
||||
This project welcomes contributions and suggestions.
|
||||
Most contributions require you to agree to a Contributor License Agreement (CLA) declaring that
|
||||
you have the right to, and actually do, grant us the rights to use your contribution.
|
||||
For details, visit [Microsoft CLA](https://cla.microsoft.com).
|
||||
|
||||
When you submit a pull request, a CLA-bot will automatically determine whether you need to
|
||||
provide a CLA and decorate the PR appropriately (e.g., label, comment).
|
||||
Simply follow the instructions provided by the bot.
|
||||
You will only need to do this once across all repos using our CLA.
|
||||
|
||||
Additionally, the pull request pipeline requires the following steps to be performed before
|
||||
mergining.
|
||||
|
||||
### Code Sign-Off
|
||||
|
||||
We require that contributors sign their commits using [`git commit --signoff`][git-commit-s]
|
||||
to certify they either authored the work themselves or otherwise have permission to use it in this project.
|
||||
|
||||
A range of commits can be signed off using [`git rebase --signoff`][git-rebase-s].
|
||||
|
||||
Please see [the developer certificate](https://developercertificate.org) for more info,
|
||||
as well as to make sure that you can attest to the rules listed.
|
||||
Our CI uses the DCO Github app to ensure that all commits in a given PR are signed-off.
|
||||
|
||||
### Linting
|
||||
|
||||
Code must pass a linting stage, which uses [`golangci-lint`][lint].
|
||||
The linting settings are stored in [`.golangci.yaml`](./.golangci.yaml), and can be run
|
||||
automatically with VSCode by adding the following to your workspace or folder settings:
|
||||
|
||||
```json
|
||||
"go.lintTool": "golangci-lint",
|
||||
"go.lintOnSave": "package",
|
||||
```
|
||||
|
||||
Additional editor [integrations options are also available][lint-ide].
|
||||
|
||||
Alternatively, `golangci-lint` can be [installed locally][lint-install] and run from the repo root:
|
||||
|
||||
```shell
|
||||
# use . or specify a path to only lint a package
|
||||
# to show all lint errors, use flags "--max-issues-per-linter=0 --max-same-issues=0"
|
||||
> golangci-lint run ./...
|
||||
```
|
||||
|
||||
### Go Generate
|
||||
|
||||
The pipeline checks that auto-generated code, via `go generate`, are up to date.
|
||||
|
||||
This can be done for the entire repo:
|
||||
|
||||
```shell
|
||||
> go generate ./...
|
||||
```
|
||||
|
||||

|
||||
## Security
|
||||
|
||||
Microsoft takes the security of our software products and services seriously, which includes all source code repositories managed through our GitHub organizations, which include [Microsoft](https://github.com/Microsoft), [Azure](https://github.com/Azure), [DotNet](https://github.com/dotnet), [AspNet](https://github.com/aspnet), [Xamarin](https://github.com/xamarin), and [our GitHub organizations](https://opensource.microsoft.com/).
|
||||
|
||||
If you believe you have found a security vulnerability in any Microsoft-owned repository that meets [Microsoft's definition of a security vulnerability](https://aka.ms/opensource/security/definition), please report it to us as described below.
|
||||
|
||||
## Reporting Security Issues
|
||||
|
||||
**Please do not report security vulnerabilities through public GitHub issues.**
|
||||
|
||||
Instead, please report them to the Microsoft Security Response Center (MSRC) at [https://msrc.microsoft.com/create-report](https://aka.ms/opensource/security/create-report).
|
||||
|
||||
If you prefer to submit without logging in, send email to [secure@microsoft.com](mailto:secure@microsoft.com). If possible, encrypt your message with our PGP key; please download it from the [Microsoft Security Response Center PGP Key page](https://aka.ms/opensource/security/pgpkey).
|
||||
|
||||
You should receive a response within 24 hours. If for some reason you do not, please follow up via email to ensure we received your original message. Additional information can be found at [microsoft.com/msrc](https://aka.ms/opensource/security/msrc).
|
||||
|
||||
Please include the requested information listed below (as much as you can provide) to help us better understand the nature and scope of the possible issue:
|
||||
|
||||
* Type of issue (e.g. buffer overflow, SQL injection, cross-site scripting, etc.)
|
||||
* Full paths of source file(s) related to the manifestation of the issue
|
||||
* The location of the affected source code (tag/branch/commit or direct URL)

|
||||
* Impact of the issue, including how an attacker might exploit the issue
|
||||
|
||||
This information will help us triage your report more quickly.
|
||||

// - files
|

// - [Hyper-V sockets]
|

//
|

// This code is similar to Go's [net] package, and uses IO completion ports to avoid

//
|

// This limits support to Windows Vista and newer operating systems.

// Additionally, this package provides support for:

// - creating and managing GUIDs
|

// - writing to [ETW]
|

// - opening and manageing VHDs

// - parsing [Windows Image files]
