2021-10-04Reply to invalid ACKs even when accept queue is fullArthur Sfez
Before checking if there is space in the accept queue, the listener should verify that the cookie is valid. If it is not, instead of silently dropping the packet, reply with an RST. Fixes #6683 PiperOrigin-RevId: 400807346

This obsoletes the need for the pendingMu and pending, since they are redundant with acceptMu and pendingAccepted. Fixes #6671. PiperOrigin-RevId: 400162391

This circular reference is misleading at best, and the various code and commentary that claim `listenEP` can be nil are impossible by definition. Add checklocks annotations to enforce preconditions. PiperOrigin-RevId: 398517574

2021-09-21Deliver endpoints to the accept queue synchronously when possibleArthur Sfez
Before this change, when a new connection was created after receiving an ACK that matched a SYN-cookie, it was always delivered asynchronously to the accept queue. There was a chance that the listening endpoint would process a SYN from another client before the delivery happened, and the listening endpoint would not know yet that the queue was about to be full, once the delivery happened. Now, when an ACK matching a SYN-cookie is received, the new endpoint is created and moved to the accept queue synchronously, while holding the accept lock. Fixes #6545 PiperOrigin-RevId: 398107254

2021-09-20Do not allow unbinding network protocolGhanan Gowripalan
Once a packet socket is bound to a network protocol, it cannot be unbound from that protocol; the network protocol binding may only be updated to a different network protocol. To comply with Linux. PiperOrigin-RevId: 397810878

2021-09-17Allow rebinding packet socket protocolGhanan Gowripalan
...to change the network protocol a packet socket may receive packets from. This CL is a portion of an originally larger CL that was split with https://github.com/google/gvisor/commit/a8ad692fd36cbaf7f5a6b9af39d601053dbee338 being the dependent CL. That CL (accidentally) included the change in the endpoint's `afterLoad` method to take the required lock when accessing the endpoint's netProto field. That change should have been in this CL. The CL that made the change mentioned in the commit message is cl/396946187. PiperOrigin-RevId: 397412582
2021-09-17Fix lock ordering violationGhanan Gowripalan
This fixes a lock ordering violations introduced in https://github.com/google/gvisor/commit/ae3bd32011889fe59bb89946532dd7ee14973696 and https://github.com/google/gvisor/commit/477d7e5e10378e2f80f21ac9f536d12c4b94d7ce when connecting/binding sockets races with handling of packets/errors as the connect/bind path takes the transport/internal/network.Endpoint.mu lock before taking stack.endpointsByNIC.mu but the locks are taken in the reverse order when handling packets/errors. The fix is to revert the change to use a lock instead of atomics in https://github.com/google/gvisor/commit/477d7e5e10378e2f80f21ac9f536d12c4b94d7ce and introduce a new lock protecting only the endpoint info in transport/internal/network.Endpoint. ``` goroutine 60 [semacquire]: sync.runtime_Semacquire(0x62c957) go/gc/src/runtime/sema.go:56 +0x25

...to catch lock-related bugs in nogo tests. Also update the endpoint's state field to be accessed while the mutex is held instead of requiring atomic operations as nothing needs to call the State method while the mutex is held. Updates #6566. PiperOrigin-RevId: 397010316

2021-09-15Pass address properties in a single structTony Gong
Replaced the current AddAddressWithOptions method with AddAddressWithProperties which passes all address properties in a single AddressProperties type. More properties that need to be configured in the future are expected, so adding a type makes adding them easier. PiperOrigin-RevId: 396930729

2021-09-14Compose raw IP with datagram-based endpointGhanan Gowripalan
A raw IP endpoint's write and socket option get/set path can use the datagram-based endpoint. This change extracts tests from UDP that may also run on Raw IP sockets. Updates #6565. Test: Raw IP + datagram-based socket syscall tests. PiperOrigin-RevId: 396729727

2021-09-14Explicitly bind endpoint to a NICGhanan Gowripalan
Previously, any time a datagram-based network endpoint (e.g. UDP) was bound, the bound NIC is always set based on the bound address (if specified). However, we should only consider the endpoint bound to an NIC if a NIC was explicitly bound to. If an endpoint has been bound to an address and attempts to send packets to an unconnected remote, the endpoint will default to sending packets through the bound address' NIC if not explicitly bound to a NIC. Updates #6565. PiperOrigin-RevId: 396712415
