2020-06-10Add support for SO_REUSEADDR to UDP sockets/endpoints.Ian Gudger
On UDP sockets, SO_REUSEADDR allows multiple sockets to bind to the same address, but only delivers packets to the most recently bound socket. This differs from the behavior of SO_REUSEADDR on TCP sockets. SO_REUSEADDR for TCP sockets will likely need an almost completely independent implementation. SO_REUSEADDR has some odd interactions with the similar SO_REUSEPORT. These interactions are tested fairly extensively and all but one particularly odd one (that honestly seems like a bug) behave the same on gVisor and Linux. PiperOrigin-RevId: 315844832

2020-06-09Fix write hang bug found by syzkaller.gVisor bot
After this change e.mu is only promoted to exclusively locked during route.Resolve. It downgrades back to read-lock afterwards. This prevents the second RLock() call gets stuck later in the stack. https://syzkaller.appspot.com/bug?id=065b893bd8d1d04a4e0a1d53c578537cde1efe99 Syzkaller logs does not contain interesting stack traces.

2020-06-09Handle removed NIC in NDP timer for packet txGhanan Gowripalan
NDP packets are sent periodically from NDP timers. These timers do not hold the NIC lock when sending packets as the packet write operation may take some time. While the lock is not held, the NIC may be removed by some other goroutine. This change handles that scenario gracefully.
