2021-04-20Expose header methods that validate checksumsArthur Sfez
This is done for IPv4, UDP and TCP headers. This also changes the packet checkers used in tests to error on zero-checksum, not sure why it was allowed before. And while I'm here, make comments' case consistent. RELNOTES: n/a Fixes #5049 PiperOrigin-RevId: 369383862

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

2019-03-26netstack: Don't exclude length when a pseudo-header checksum is calculatedAndrei Vagin
This is a preparation for GSO changes (cl/234508902). RELNOTES[gofers]: Refactor checksum code to include length, which it already did, but in a convoluted way. Should be a no-op. PiperOrigin-RevId: 240460794 Change-Id: I537381bc670b5a9f5d70a87aa3eb7252e8f5ace2
