2020-07-27Add ability to send unicast ARP requests and Neighbor SolicitationsSam Balana
The previous implementation of LinkAddressRequest only supported sending broadcast ARP requests and multicast Neighbor Solicitations. The ability to send these packets as unicast is required for Neighbor Unreachability Detection.

2020-07-27Fix memory accounting in TCP pending segment queue.Bhasker Hariharan
TCP now tracks the overhead of the segment structure itself in it's out-of-order queue (pending). This is required to ensure that a malicious sender sending 1 byte out-of-order segments cannot queue like 1000's of segments which bloat up memory usage. We also reduce the default receive window to 32KB. With TCP moderation there is no need to keep this window at 1MB which means that for new connections the default out-of-order queue will be small unless the application actually reads the data that is being sent. This prevents a sender from just maliciously filling up pending buf with lots of tiny out-of-order segments. PiperOrigin-RevId: 323450913

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.

At present, when doing syscall_kvm test, we need to enable the function of ESR_ELx_SYS64_ISS_SYS_CNTVCT/ESR_ELx_SYS64_ISS_SYS_CNTFRQ to successfully pass the test. I set CNTKCTL_EL1.EL0VCTEN==1/CNTKCTL_EL1.EL0PCTEN==1, so that the related cases can passed. Signed-off-by: Bin Lu <bin.lu@arm.com>

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
