2020-08-13[vfs2][gofer] Fix file creation flags sent to gofer.Ayush Ranjan
Fixes php runtime test ext/standard/tests/file/readfile_basic.phpt Fixes #3516 fsgofers only want the access mode in the OpenFlags passed to Create(). If more flags are supplied (like O_APPEND in this case), read/write from that fd will fail with EBADF. See runsc/fsgofer/fsgofer.go:WriteAt() VFS2 was providing more than just access modes. So filtering the flags using p9.OpenFlagsModeMask == linux.O_ACCMODE fixes the issue. Gofer in VFS1 also only extracts the access mode flags while making the create RPC. See pkg/sentry/fs/gofer/path.go:Create() Even in VFS2, when we open a handle, we extract out only the access mode flags + O_TRUNC. See third_party/gvisor/pkg/sentry/fsimpl/gofer/handle.go:openHandle() Added a test for this. PiperOrigin-RevId: 326574829

2020-08-13Use the user supplied MSS for accepted connectionsGhanan Gowripalan
This change supports using the user supplied MSS (TCP_MAXSEG socket option) for new socket connections created from a listening TCP socket. Note that the user supplied MSS will only be used if it is not greater than the maximum possible MSS for a TCP connection's route. If it is greater than the maximum possible MSS, the MSS will be capped at that maximum value. Test: tcp_test.TestUserSuppliedMSSOnListenAccept PiperOrigin-RevId: 326567442

2020-08-13Migrate to PacketHeader API for PacketBuffer.Ting-Yu Wang
Formerly, when a packet is constructed or parsed, all headers are set by the client code. This almost always involved prepending to pk.Header buffer or trimming pk.Data portion. This is known to prone to bugs, due to the complexity and number of the invariants assumed across netstack to maintain. In the new PacketHeader API, client will call Push()/Consume() method to construct/parse an outgoing/incoming packet. All invariants, such as slicing and trimming, are maintained by the API itself. NewPacketBuffer() is introduced to create new PacketBuffer. Zero value is no longer valid. PacketBuffer now assumes the packet is a concatenation of following portions: * LinkHeader * NetworkHeader * TransportHeader * Data Any of them could be empty, or zero-length.

2020-08-13Ensure TCP TIME-WAIT is not terminated prematurely.Bhasker Hariharan
Netstack's TIME-WAIT state for a TCP socket could be terminated prematurely if the socket entered TIME-WAIT using shutdown(..., SHUT_RDWR) and then was closed using close(). This fixes that bug and updates the tests to verify that Netstack correctly honors TIME-WAIT under such conditions. Fixes #3106 PiperOrigin-RevId: 326456443
