2021-09-09Remove linux-compat loopback hacks from packet endpointGhanan Gowripalan
Previously, gVisor did not represent loopback devices as an ethernet device as Linux does. To maintain Linux API compatibility for packet sockets, a workaround was used to add an ethernet header if a link header was not already present in the packet buffer delivered to a packet endpoint. However, this workaround is a bug for non-ethernet based interfaces; not all links use an ethernet header (e.g. pure L3/TUN interfaces). As of 3b4bb947517d0d9010120aaa1c3989fd6abf278e, gVisor represents loopback devices as an ethernet-based device so this workaround can now be removed. BUG: https://fxbug.dev/81592 Updates #6530, #6531. PiperOrigin-RevId: 395819151

2021-09-09Remove link/packetsocketGhanan Gowripalan
This change removes NetworkDispatcher.DeliverOutboundPacket. Since all packet writes go through the NIC (the only NetworkDispatcher), we can deliver outgoing packets to interested packet endpoints before writing the packet to the link endpoint as the stack expects that all packets that get delivered to a link endpoint are transmitted on the wire. That is, link endpoints no longer need to let the stack know when it writes a packet as the stack already knows about the packet it writes through a link endpoint. PiperOrigin-RevId: 395761629

2021-09-02unix: avoid taking two endpoint locksAndrei Vagin
If we want to take two endpoint locks, we need to be sure that we always take them in the same order. Accept() locks the listening endpoint to work with acceptedChan and then it calls GetLocalAddress that locks an accepted endpoint. Actually, we can release the listening endpoint lock before calling GetLocalAddress. Reported-by: syzbot+f52bd603f51a4ae91054@syzkaller.appspotmail.com PiperOrigin-RevId: 394553823

2021-09-01Support sending with packet socketsGhanan Gowripalan
...through the loopback interface, only. This change only supports sending on packet sockets through the loopback interface as the loopback interface is the only interface used in packet socket syscall tests - the other link endpoints are not excercised with the existing test infrastructure. Support for sending on packet sockets through the other interfaces will be added as needed. BUG: https://fxbug.dev/81592 PiperOrigin-RevId: 394368899

For a small receive buffer the first out-of-order segment will get accepted and fill up the receive buffer today. This change now includes the size of the out-of-order segment when checking whether to queue the out of order segment or not. PiperOrigin-RevId: 394351309

2021-09-01Extract network datagram endpoint common facilitiesGhanan Gowripalan
...from the UDP endpoint. Datagram-based transport endpoints (e.g. UDP, RAW IP) can share a lot of their write path due to the datagram-based nature of these endpoints. Extract the common facilities from UDP so they can be shared with other transport endpoints (in a later change). Test: UDP syscall tests. PiperOrigin-RevId: 394347774
