This allows nested containers to use autoetc, and increases compatibility with other implementations.

This ensures a signal gets delivered to the process instead of relying on parent death behaviour.
SIGCONT was chosen as it is the only signal an unprivileged process is allowed to send to processes with different credentials.
A custom signal handler is installed because the Go runtime does not expose signal information other than which signal was received, and shim must check pid to ensure reasonable behaviour.

This removes the unnecessary creation and destruction of share paths when none of the enablements making use of them are set.

This prepares for the separation of app and sandbox tests.

This is an ugly fix that makes various assumptions guaranteed to hold true in the testing vm. The test package is filtered by the build system so some ugliness is tolerable here.

This is as ugly as it is because it has to have CAP_SYS_ADMIN and not be in seccomp mode.

Some test elements implemented in the test tool might need to run outside the sandbox. This change allows that to happen.

This improves readability and allows gofmt to format the file.

Inheritable should not be able to affect anything regardless of its value, due to no_new_privs.

During development the syscall filter caused me to make an incorrect assumption about SysProcAttr.

Many programs complain about this.

This is copied at runtime because it appears to be impossible to obtain this path in nix.

The race detector really slows down container tooling.

This is now handled by the setup op. This also gets rid of the hardcoded /etc path.

This makes no difference currently but has different behaviour in the native sandbox.

Native container tooling is severely slowed down by race detector. Raise timeout so it reliably completes.

By default test vm commands run as root, this causes buildFHSEnv bwrap to cover some parts of /proc, making it impossible to mount proc in a mount namespace created under it. Running as a regular user gets around this issue.

A field is bypassed if it contains a single null byte. This will never appear in the text format so is safe to use.
