2020-01-09New sync package.Ian Gudger
* 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. Updates #1472 PiperOrigin-RevId: 289033387

2020-01-08Return correct length with MSG_TRUNC for unix sockets.Ian Lewis
This change calls a new Truncate method on the EndpointReader in RecvMsg for both netlink and unix sockets. This allows readers such as sockets to peek at the length of data without actually reading it to a buffer. Fixes #993 #1240 PiperOrigin-RevId: 288800167

2020-01-08Write simple ACCEPT rules to the filter table.Kevin Krakauer
This gets us closer to passing the iptables tests and opens up iptables so it can be worked on by multiple people. A few restrictions are enforced for security (i.e. we don't want to let users write a bunch of iptables rules and then just not enforce them): - Only the filter table is writable. - Only ACCEPT rules with no matching criteria can be added.

2020-01-06platform/syscall: use syscall + int3 to execute a system call in a stub processAndrei Vagin
Right now, we need to call ptrace(PTRACE_SYSCALL) and wait() twice to execute one system call in a stub process. With these changes, we will need to call ptrace + wait only once. In addition, this allows to workaround the kernel bug when a stub process doesn't stop on syscall-exit-stop and starts executing the next system call.

- Renamed memfs to tmpfs. - Copied fileRangeSet bits from fs/fsutil/ to fsimpl/tmpfs/ - Changed tmpfs to be backed by filemem instead of byte slice. - regularFileReadWriter uses a sync.Pool, similar to gofer client. PiperOrigin-RevId: 288356380

2020-01-06Cleanup Shm reference handlingMichael Pratt
Currently, shm.Registry.FindByID will return Shm instances without taking an additional reference on them, making it possible for them to disappear. More explicitly handle references. All callers hold a reference for the duration that they hold the instance. Registry.shms may transitively hold Shms with no references, so it must TryIncRef to determine if they are still valid.

2019-12-30Add VFS2 support for device special files.Jamie Liu
- Add FileDescriptionOptions.UseDentryMetadata, which reduces the amount of boilerplate needed for device FDs and the like between filesystems. - Switch back to having FileDescription.Init() take references on the Mount and Dentry; otherwise managing refcounts around failed calls to OpenDeviceSpecialFile() / Device.Open() is tricky.
