2 =====

4 This is a prototype for plumbing Mojo into the NaCl sandbox. It is

5 currently insecure (see below), does not provide a stable ABI (IRT

6 support must be added), and does not support Mojo functions that

7 return pointers (for example, `MojoMapBuffer`).

10 Using

11 =====

12

13 To use this prototype, point your `.gclient` file to `DEPS.nacl` instead

14 of `DEPS` and then run `gclient sync`.

15

16 When you run `mojo/tools/mojob.py gn`, add `--nacl` to the command line.

17

18 Run `mojo/tools/mojob.py nacltest` for additional nacl-specific tests.

21 Notes

22 =====

23

24 `generator/interface.py` contains a programmatic description of the

25 stable Mojo interface. This will need to be updated as the interface

26 changes. Run `generator/generate_nacl_bindings.py` to generate the

27 bindings that plumb this interface into the NaCl sandbox.

30 Security TODO

31 =============

32

33 * Separate trusted and untrusted Mojo handles.

34 * Validate and copy option structures.

35 * Protect untrusted buffers passed into Mojo:

36 * `NaClVmIoWillStart/HasEnded`.

37 * volatile accesses to untrusted memory (untrusted code could race).

38 * Overflow checking in array bounds validation.
