2019-03-04Reconcile DHCP with SO_BROADCASTTamir Duberstein
Now that we have SO_BROADCAST, we don't need (some of) the hackery in the DHCP client. This also fixes a bizarre regression observed in Fuchsia where DHCP acquisition was taking over two minutes. PiperOrigin-RevId: 236661954 Change-Id: Ibcfe5d311fa5df8ff4ff2e40ccedffe91f92daa5
2019-02-20Implement Broadcast supportAmanda Tait
This change adds support for the SO_BROADCAST socket option in gVisor Netstack. This support includes getsockopt()/setsockopt() functionality for both UDP and TCP endpoints (the latter being a NOOP), dispatching broadcast messages up and down the stack, and route finding/creation for broadcast packets. Finally, a suite of tests have been implemented, exercising this functionality through the Linux syscall API. PiperOrigin-RevId: 234850781 Change-Id: If3e666666917d39f55083741c78314a06defb26c

This change also adds extensive testing to the p9 package via mocks. The sanity checks and type checks are moved from the gofer into the core package, where they can be more easily validated. PiperOrigin-RevId: 218296768 Change-Id: I4fc3c326e7bf1e0e140a454cbacbcc6fd617ab55

2018-09-28Block for link address resolutionSepehr Raissian
Previously, if address resolution for UDP or Ping sockets required sending packets using Write in Transport layer, Resolve would return ErrWouldBlock and Write would return ErrNoLinkAddress. Meanwhile startAddressResolution would run in background. Further calls to Write using same address would also return ErrNoLinkAddress until resolution has been completed successfully. Since Write is not allowed to block and System Calls need to be interruptible in System Call layer, the caller to Write is responsible for blocking upon return of ErrWouldBlock. Now, when startAddressResolution is called a notification channel for the completion of the address resolution is returned. The channel will traverse up to the calling function of Write as well as ErrNoLinkAddress. Once address resolution is complete (success or not) the channel is closed. The caller would call Write again to send packets and check if address resolution was compeleted successfully or not.
