2020-02-12iptables: User chainsKevin Krakauer
- Adds creation of user chains via `-N <chainname>` - Adds `-j RETURN` support for built-in chains, which triggers the chain's underflow rule (usually the default policy). - Adds tests for chain creation, default policies, and `-j RETURN' from built-in chains.

2020-02-11Ensure fsimpl/gofer.dentryPlatformFile.hostFileMapper is initialized.gVisor bot
Fixes #1812. (The more direct cause of the deadlock is panic unsafety because the historically high cost of defer means that we avoid it in hot paths, including much of MM; defer is much cheaper as of Go 1.14, but still a measurable overhead.) PiperOrigin-RevId: 294560316

2020-02-06Send DAD event when DAD resolves immediatelyGhanan Gowripalan
Previously, a DAD event would not be sent if DAD was disabled. This allows integrators to do some work when an IPv6 address is bound to a NIC without special logic that checks if DAD is enabled. Without this change, integrators would need to check if a NIC has DAD enabled when an address is auto-generated. If DAD is enabled, it would need to delay the work until the DAD completion event; otherwise, it would need to do the work in the address auto-generated event handler. Test: stack_test.TestDADDisabled PiperOrigin-RevId: 293732914

2020-02-06Auto-generate link-local address as a SLAAC addressGhanan Gowripalan
Auto-generated link-local addresses should have the same lifecycle hooks as global SLAAC addresses. The Stack's NDP dispatcher should be notified when link-local addresses are auto-generated and invalidated. They should also be removed when a NIC is disabled (which will be supported in a later change). Tests: - stack_test.TestNICAutoGenAddrWithOpaque - stack_test.TestNICAutoGenAddr PiperOrigin-RevId: 293706760
