Amit fd34511314 Switch to Go 1.23 and fix CI failures
Some new upcoming changes require us to use Go 1.23. However, if we switch to Go 1.23 some
new linter errors are showing up. This commit fixes most of the errors and adds an
exclusion for integer overflow errors.

Hamza El-Saawy bc421d9108 Bug: Close hvsock handle on listen error; fix tests (#310)
* Bug: Close hvsock handle on listen error; fix tests

Close the socket created in
`github.com/Microsoft/go-winio/pkg/ListenHvsock` if either the `Bind` or
`Listen` calls fail.

Go changed `filepath.VolumeName` code, resulting in different behavior in
`github.com/Microsoft/go-winio/pkg/fs.GetFileSystemType`.
Update test accordingly.
Also add more debug logs to `pkg\fs\resolve_test.go`.

Also, move add skip for fuzzing on WS2019 or older to `FuzzHvSockRxTx`
code directly, instead of in ci.yml.

See: https://go-review.googlesource.com/c/go/+/540277

Hamza El-Saawy 9f0d5dc7d2 Switch from sycall to windows (#295)
Where ever possible, use `golang.org/x/sys/windows` instead of `syscall`
(which has been deprecated since go1.11).

Using `windows.LocalFree` requires using `unsafe.Pointer`, which ensures
that the Go garbage collector does not try to free memory pre-maturely
if it was previously declared as a pointer.

Since `syscall.Handle` is part of API for `vhd` package, it was left
unchanged.

For security descriptor functions, switch to using
`windows.SECURITY_DESCRIPTOR` to avoid unnecessary byte manipulation and
panics due to missing input validation and error checking.

Hamza El-Saawy e268c11e27 Add lint and go generate steps to CI (#254)
* Add lint and go generate stages to CI

Add CI step to verify `go generate` was run on repo.
Add linter stage to CI along with linter config file,
`.golangci.yml`.
Will likely prefer revive over static-check.

Updated README Contributing section on linting requirements.

Added sequence ordering to make sure lint and go generate stages run
before tests and build.
This way, build and tests are not run on code that could potentially:

    1. not build due to `gofmt` issues;
    2. contain bugs;
    3. have to be re-submitted after issues are fixed; or
    4. contain outdated Win32 syscall or other auto-generated files.

* Fixed linter issues

Code changes to satisfy linters:

 - Ran `gofmt -s -w` on repo.
 - Broke up long lines.
 - When possible, changed names with incorrect initialism formatting
   - Added exceptions for exported variables.
 - Added exceptions for ALL_CAPS_WITH_UNDERSCORES code.
   - Switched to using `windows` or `syscall` definitions if possible;
     especially if some constants were unused.
 - Added `_ =` to satisfy error linter, and acknowledge that errors are
   being ignored.
 - Switched to using `errors.Is` and `As` in places, elsewhere added
   exceptions if error value was known to be `syscall.Errno`.
 - Removed bare returns.
 - Prevented variables from being overshadowed in certain places
   (ignoring cases of overshadowing `err`).
 - Renamed variables and functions (eg, `len`, `eventMetadata.bytes`) to
   prevent shadowing pre-built functions and imported pacakges.
 - Removed unused method receivers.
 - Added exceptions to certain unused (unexported) constants and
   functions.
   - Deleted unused `once` from `pkg/etw.providerMap`.
 - Renamed `noop.go` files to `main_other.go` or `doc.go`, to better fit
   style recommendations.
 - Added exceptions for non-secure use of SHA1 and weak crypto
   libraries.
 - Replaced `ioutil` with `io` and `os` (and `t.TempDir` in tests).
 - Added fully exhaustive checks for `switch` statements in `pkg/etw`.
 - Defined constant strings for `tools/mkwinsyscall`.
 - Removed unnecessary conversions.
 - Made sure `context.Cancel` was called.

Additionally, added `//go:build windows" constraints on files with
unexported code, since linter will complain about unused code on
non-Windows platforms.

Added a stub `main() {}` for `mkwinsyscall` for non-Windows builds, just in
case `//go:generate` directives are added to OS-agnostic files.

Hamza El-Saawy d68e55cd0b Added HV Socket known IDs, Dial, bug fixes (#239)
* Added HV Socket known IDs, Dial, bug fixes

Added:
* Well-know Hyper-V VMIDs for parents, children, and loopback.
* VSock interop service GUID.
* `Dial()` and `DialContext()` to dial a specific Hyper-V socket at a
  known address (along with a corresponding `HvsockDialer` struct.

Bug fixes:
* Dial (and Listen) now properly initialize and set properties of their
  sockets after ConnectEx (and AcceptEx).
* The `socketError` used by `bind` was incorrect, it should be `int32(-1)`,
  not `uintptr(^0)`
* Return errors for `(*HvsockConn) SetDeadline`

Created a `sockets` package, currently only with syscalls to `Bind`,
`ConnectEx` and `GetSockName`, bypassing `syscall/windows` restrictions
on the types that can do so.

Hamza El-Saawy 0aa6c0a16b HvsockConn shutdown, and .IsClosed() function
Corrected `HvsockConn` `CloseRead`/`Write` to check if the socket
has been closed before attempting to shutdown the socket for
reading or writing.
Additionally, `shutdown` was not respecting whether to shutdown reading
or writing, and only shutting down the socket for reading.

Added `IsClosed` function to `win32File` (and therefore `win32Pipe` and
`win32MessageBytePipe`) and `HvsockConn` to check if the socket/pipe
has been closed already.
