2019-06-06Track and export socket state.Rahat Mahmood
This is necessary for implementing network diagnostic interfaces like /proc/net/{tcp,udp,unix} and sock_diag(7). For pass-through endpoints such as hostinet, we obtain the socket state from the backend. For netstack, we add explicit tracking of TCP states. PiperOrigin-RevId: 251934850

2019-05-21Add basic plumbing for splice and stub implementation.Adin Scannell
This does not actually implement an efficient splice or sendfile. Rather, it adds a generic plumbing to the file internals so that this can be added. All file implementations use the stub fileutil.NoSplice implementation, which causes sendfile and splice to fall back to an internal copy. A basic splice system call interface is added, along with a test. PiperOrigin-RevId: 249335960 Change-Id: Ic5568be2af0a505c19e7aec66d5af2480ab0939b

hostinet/socket.go: the Sentry doesn't spawn new processes, but it doesn't hurt to protect the socket from leaking. unet/unet.go: should be setting closing on exec.

2018-05-16Refcount socket Dirents correctly.Christopher Koch
This should fix the socket Dirent memory leak. fs.NewFile takes a new reference. It should hold the *only* reference. DecRef that socket Dirent. Before the globalDirentMap was introduced, a mis-refcounted Dirent would be garbage collected when all references to it were gone. For socket Dirents, this meant that they would be garbage collected when the associated fs.Files disappeared. After the globalDirentMap, Dirents *must* be reference-counted correctly to be garbage collected, as Dirents remove themselves from the global map when their refcount goes to -1 (see Dirent.destroy). That removes the last pointer to that Dirent. PiperOrigin-RevId: 196878973 Change-Id: Ic7afcd1de97c7101ccb13be5fc31de0fb50963f0
