syndtr / gocapability Goto Github PK

Please consider assigning version numbers and tagging releases. Tags/releases
are useful for downstream package maintainers (in Debian and other distributions) to export source tarballs, automatically track new releases and to declare dependencies between packages. Read more in the Debian Upstream Guide.

Versioning provides additional benefits to encourage vendoring of a particular (e.g. latest stable) release contrary to random unreleased snapshots.

Thank you.

Is there a way to access the data of security.capability?

I want to add capabilities to files in a tar archive. This library would do exactly what I need, except that it seems like there is no way to get the actual data. I only found setVfsCap which directly sets it on a file. It would be great if there would be something like VFSCap() []byte which would return a byte array which I can directly write into a PAXRecords from the golang tar library.

Hello, I wrote a test program, as following:
package main

import (
"fmt"
"github.com/syndtr/gocapability/capability"
)

func main() {
processCaps, err := capability.NewPid(0)
if err != nil {
fmt.Println("failed to create pid")
}
processCaps.Set(capability.BOUNDING,capability.CAP_CHOWN)
processCaps.Set(capability.EFFECTIVE,capability.CAP_CHOWN)
processCaps.Set(capability.PERMITTED,capability.CAP_CHOWN)
processCaps.Set(capability.INHERITABLE,capability.CAP_CHOWN)
processCaps.Set(capability.AMBIENT,capability.CAP_CHOWN)
if err := processCaps.Apply(capability.CAPS | capability.BOUNDS | capability.AMBIENT); err != nil {
fmt.Println("failed to apply")
}

processCaps2, err := capability.NewPid(0)
if err != nil {
    fmt.Println("failed to create pid")
}   
set := processCaps2.Get(capability.AMBIENT, capability.CAP_CHOWN)
if !set {
    fmt.Println("failed to set")
}   

}

And the result is
$ sudo go run test.go
failed to set

Is there a bug with library or used it in a wrong way?

Please, Write README file about the packages and its API.
