* Stop installing the cap and psx packages, but do install captree.Andrew G. Morgan2021-08-261-0/+4
| | | | | | | | | | | | | | | | | We also add the cap.ProcRoot() API to let the user redirect to their local /proc/ directory - in case anyone runs with an unusual setup like that. I've been studying the downstream package definitions and no one it doesn't seem popular to build the Go packages. Indeed, Go folk themselves prefer to install via modules anyway, so we're getting with the program. However, if folk want to build test the Go stuff as part of a package build and run an install as well, we reward them with the 'captree' binary. Signed-off-by: Andrew G. Morgan <morgan@kernel.org>

* Add the captree example.Andrew G. Morgan2021-08-222-0/+324
| | | | | | | | | | | | This is a small command line utility for doing something like pstree but focused on revealing the full capability state of the processes and threads shown. This requires support provided in the cap.IABGetPID() function which will debut in libcap-2.54. For now, the binary is only buildable from HEAD in the git repository. Signed-off-by: Andrew G.

* Upgrade cap and psx Go modules to version 1.2.48psx/v1.2.48cap/v1.2.48Andrew G. Morgan2021-02-043-4/+4
| | | | | | | | | | | Go has its own notion of major version, and this commit raises it from 0 to 1. That is, these modules should now be considered stable. The sources for the 1.2.48 and the 0.2.48 modules are otherwise identical. Signed-off-by: Andrew G. Morgan <morgan@kernel.org>

* Add a go.mod file for building gowns.Andrew G. Morgan2020-12-081-0/+5
| | | | | | | | | | | | | | | Since go 1.15 doesn't require the wrapping linker trick, I'm recommending that version of Go for building it. Also add a test of building the setid and gowns sources in the .../go/ directory. At this stage, I'm imagining a tutorial on how gowns works here: https://sites.google.com/site/fullycapable/getting-started-with-go but I haven't started writing that yet. I first want to confirm the state of all the features I want to use. Signed-off-by: Andrew G. Morgan <morgan@kernel.org>

* Demonstrate using libcap and namespaces in Go.Andrew G. Morgan2020-11-281-0/+181
| | | | | | | | | A short program in Go that can invoke a UID namespaced application it can also be used to launch capability modified programs using IAB and mode. This is a reduced feature set over the more complete capsh program - with the exception of namespace support. Signed-off-by: Andrew G. Morgan <morgan@kernel.org>

I've written up how to build web.go here: https://sites.google.com/site/fullycapable/building-go-programs-that-manipulate-capabilities But it struc me that the code itself does not explain about the CGO_LDFLAGS_ALLOW workaround, so I've relocated the web.go code and included a README as well as a pointer to the above explanation.
