gVisor on Linux 5.15

[Wenhui Zhang]

Hi, everyone:

Anyone tried to run gVisor on 5.15 please?

If I would like to get it work on 5.15, what engineering work should I make please?

Hi Wenhui,

What platform are you using to run runsc on Linux 5.15? And what issues are you having?

When building through docker commands (make copy TARGETS=runsc DESTINATION=bin/), I met no errors, however after I switched to golang native compilation[2], I encountered some errors shown below:

~/gvisor# echo "module runsc" > go.mod

~/gvisor# GO111MODULE=on go get gvisor.dev/gvisor/runsc@go

go: finding gvisor.dev/gvisor/runsc go

go: finding gvisor.dev/gvisor go

build gvisor.dev/gvisor/runsc: cannot find module for path embed

~/gvisor# CGO_ENABLED=0 GO111MODULE=on sudo -E go build -o /usr/local/bin/runsc gvisor.dev/gvisor/runsc

build gvisor.dev/gvisor/runsc: cannot find module for path embed

I haven't been able to reproduce this.

Can you provide more information, like which version of Go you are using, which Linux distribution version? Are your packages up-to-date?

Do you have Go-related environment variables set beyond the ones shown in the command-lines?

Are you running this from a checked-out repository of the gVisor repo, and if so, which commit hash?

Have you tried compiling it through the Makefile instead, and what output do you get for that?
From the master branch:
$ mkdir -p bin
$ make copy TARGETS=runsc DESTINATION=bin/
$ sudo cp ./bin/runsc /usr/local/bin

Etienne,

This may be some kind of issue with the go branch which contains a go gettable version of gvisor project. Perhaps the "embed" package is not being exported properly?

See: https://github.com/google/gvisor/blob/master/tools/go_branch.sh

What version of Go are you using? Does the same issue occur with Go 1.19?
