Kevin KrakauerandgVisor bot d01751e25e sentry: use a stronger RNG for address space randomization
Since everything fits inside an int64, we avoid using crypto/rand.Int, which
can allocate and uses the much more complex big.Int.

Kevin KrakauerandgVisor bot 83f75082e5 nestack: use cryptographically secure RNG when appropriate
This addresses an issue discovered by Inon Kaplan (PhD candidate in the
Hebrew University School of Computer Science and Engineering), Ron Even (BSc
graduate of Bar Ilan University) and Amit Klein (faculty member in the Hebrew
University School of Computer Science and Engineering). Details will be
provided in their paper, to be presented in a forthcoming academic conference.

Also:
- Add a secure RNG type to prevent mixing up with the default PRNG
- Give the PRNG the name `InsecureRNG` to make it more obvious to future
  contributors that some RNGs are inappropriate in certain instances.
- Some tests were injecting fake RNGs and had to be relaxed: they relied on the
  stack calling the RNG a specific number of times and in a specific order.
  That order is now changed, and is too brittle to unit test.
- Remove the double package comment in pkg/rand. The linter complains.

Ian GudgerandgVisor bot 27500d529f New sync package.
* Rename syncutil to sync.
* Add aliases to sync types.
* Replace existing usage of standard library sync package.

This will make it easier to swap out synchronization primitives. For example,
this will allow us to use primitives from github.com/sasha-s/go-deadlock to
check for lock ordering violations.

Adin ScannellandShentubot 75cd70ecc9 Track paths and provide a rename hook.
This change also adds extensive testing to the p9 package via mocks. The sanity
checks and type checks are moved from the gofer into the core package, where
they can be more easily validated.

Zhaozhong NiandShentubot be7fcbc558 stateify: support explicit annotation mode; convert refs and stack packages.
We have been unnecessarily creating too many savable types implicitly.
