2020-07-29Add FUSE_INITJinmou Li
This change allows the sentry to send FUSE_INIT request and process the reply. It adds the corresponding structs, employs the fuse device to send and read the message, and stores the results of negotiation in corresponding places (inside connection struct). It adds a CallAsync() function to the FUSE connection interface: - like Call(), but it's for requests that do not expect immediate response (init, release, interrupt etc.) - will block if the connection hasn't initialized, which is the same for Call()

2020-07-27Add device implementation for /dev/fuseRidwan Sharif
This PR adds the following: - [x] Marshall-able structs for fuse headers - [x] Data structures needed in /dev/fuse to communicate with the daemon server - [x] Implementation of the device interface - [x] Go unit tests This change adds the `/dev/fuse` implementation. `Connection` controls the communication between the server and the sentry. The FUSE server uses the `FileDescription` interface to interact with the Sentry. The Sentry implmenetation of fusefs, uses `Connection` and the Connection interface to interact with the Server. All communication messages are in the form of `go_marshal` backed structs defined in the ABI package. This change also adds some go unit tests that test (pretty basically) the interfaces and should be used as an example of an end to end FUSE operation.

2020-07-23Add permission checks to vfs2 truncate.Dean Deng
- Check write permission on truncate(2). Unlike ftruncate(2), truncate(2) fails if the user does not have write permissions on the file. - For gofers under InteropModeShared, check file type before making a truncate request. We should fail early and avoid making an rpc when possible. Furthermore, depending on the remote host's failure may give us unexpected behavior--if the host converts the truncate request to an ftruncate syscall on an open fd, we will get EINVAL instead of EISDIR. Updates #2923. PiperOrigin-RevId: 322913569

2020-07-23Add AfterFunc to tcpip.ClockSam Balana
Changes the API of tcpip.Clock to also provide a method for scheduling and rescheduling work after a specified duration. This change also implements the AfterFunc method for existing implementations of tcpip.Clock. This is the groundwork required to mock time within tests. All references to CancellableTimer has been replaced with the tcpip.Job interface, allowing for custom implementations of scheduling work. This is a BREAKING CHANGE for clients that implement their own tcpip.Clock or use tcpip.CancellableTimer. Migration plan: 1. Add AfterFunc(d, f) to tcpip.Clock 2. Replace references of tcpip.CancellableTimer with tcpip.Job 3. Replace calls to tcpip.CancellableTimer#StopLocked with tcpip.Job#Cancel 4. Replace calls to tcpip.CancellableTimer#Reset with tcpip.Job#Schedule 5. Replace calls to tcpip.NewCancellableTimer with tcpip.NewJob. PiperOrigin-RevId: 322906897

2020-07-23Add task work mechanism.Dean Deng
Like task_work in Linux, this allows us to register callbacks to be executed before returning to userspace. This is needed for kcov support, which requires coverage information to be up-to-date whenever we are in user mode. We will provide coverage data through the kcov interface to enable coverage-directed fuzzing in syzkaller. One difference from Linux is that task work cannot queue work before the transition to userspace that it precedes; queued work will be picked up before the next transition.
