* pkg/loopback: use ioctl helpers from x/sys/unixSebastiaan van Stijn2022-10-084-96/+12
| | | | | | | | | | Use the IoctlRetInt, IoctlSetInt and IoctlLoopSetStatus64 helper functions defined in the golang.org/x/sys/unix package instead of manually wrapping these using a locally defined function. Inspired by https://github.com/containerd/containerd/commit/3cc3d8a560a9d070466d7d58010beda61db5c1ba Signed-off-by: Sebastiaan van Stijn <github@gone.nl>

* Use correct `LOOP_CTL_GET_FREE` API in `pkg/loopback`Daniel Sweet2019-08-271-3/+7
| | | | | | | | | | | | | | | | | | | | The `ioctl` interface for the `LOOP_CTL_GET_FREE` request on `/dev/loop-control` is a little different from what `unix.IoctlGetInt` expects: the first index is the returned status in `r1`, not an `int` pointer as the first parameter. Unfortunately we have to go a little lower level to get the appropriate loop device index out, using `unix.Syscall` directly to read from `r1`. Internally, the index is returned as a signed integer to match the internal `ioctl` expectations of interpreting a negative signed integer as an error at the userspace ABI boundary, so the direct interface of `ioctlLoopCtlGetFree` can remain as-is.

* loopback: separate loop logic from devicemapperVincent Batts2015-12-184-0/+305
