2019-10-03Don't report partialResult errors from sendfileAndrei Vagin
The input file descriptor is always a regular file, so sendfile can't lose any data if it will not be able to write them to the output file descriptor. Reported-by: syzbot+22d22330a35fa1c02155@syzkaller.appspotmail.com PiperOrigin-RevId: 272730357
2019-09-12Implement splice methods for pipes and sockets.Adin Scannell
This also allows the tee(2) implementation to be enabled, since dup can now be properly supported via WriteTo. Note that this change necessitated some minor restructoring with the fs.FileOperations splice methods. If the *fs.File is passed through directly, then only public API methods are accessible, which will deadlock immediately since the locking is already done by fs.Splice. Instead, we pass through an abstract io.Reader or io.Writer, which elide locks and use the underlying fs.FileOperations directly. PiperOrigin-RevId: 268805207
