2021-10-07add convenient wrapper for eventfdKevin Krakauer
The same create/write/read pattern is copied around several places. It's easier to understand in a package with names and comments, and we can reuse the smart blocking code in package rawfile. PiperOrigin-RevId: 401647108

2021-09-14Fix bug in RecvMMsgDispatcher.Bhasker Hariharan
Fixed a bug introduced in the following commit: https://github.com/google/gvisor/commit/979d6e7d77b17e94defc29515180cc75d3560383 The commit introduced a bug which causes the recvmmsg dispatcher to never exit as BlockingPoll is now called with two fds and poll will not return an error anymore if one of the FD is closed. We need to explicitly check the events for each FD to determine if the sentry FD is closed. ReadV dispatcher does not have the same issue as Readv does not rely on sk_err field of the underlying socket to determine if the socket is in an error state. Recvmmsg OTOH seems to get confused and always returns EAGAIN if poll() is called which queries the sk_err field and clears it. PiperOrigin-RevId: 396676135

2021-07-30Support RTM_DELLINKZeling Feng
This change will allow us to remove the default link in a packetimpact test so we can reduce indeterministic behaviors as required in https://fxbug.dev/78430. This will also help with testing #1388. Updates #578, #1388. PiperOrigin-RevId: 387896847

2021-07-30checklinkname: rudimentary type-checking of linkname directivesMichael Pratt
This CL introduces a 'checklinkname' analyzer, which provides rudimentary type-checking that verifies that function signatures on the local and remote sides of //go:linkname directives match expected values. If the Go standard library changes the definitions of any of these function, checklinkname will flag the change as a finding, providing an error informing the gVisor team to adapt to the upstream changes. This allows us to eliminate the majority of gVisor's forward-looking negative build tags, as we can catch mismatches in testing [1]. The remaining forward-looking negative build tags are covering shared struct definitions, which I hope to add to checklinkname in a future CL. [1] Of course, semantics/requirements can change without the signature changing, so we still must be careful, but this covers the common case. PiperOrigin-RevId: 387873847

2021-03-03[op] Replace syscall package usage with golang.org/x/sys/unix in pkg/.Ayush Ranjan
The syscall package has been deprecated in favor of golang.org/x/sys. Note that syscall is still used in the following places: - pkg/sentry/socket/hostinet/stack.go: some netlink related functionalities are not yet available in golang.org/x/sys. - syscall.Stat_t is still used in some places because os.FileInfo.Sys() still returns it and not unix.Stat_t.

2020-07-15fdbased: Vectorized write for packet; relax writev syscall filter.Ting-Yu Wang
Now it calls pkt.Data.ToView() when writing the packet. This may require copying when the packet is large, which puts the worse case in an even worse situation. This sent out in a separate preparation change as it requires syscall filter changes. This change will be followed by the change for the adoption of the new PacketHeader API.

2020-04-23Remove View.First() and View.RemoveFirst()Kevin Krakauer
These methods let users eaily break the VectorisedView abstraction, and allowed netstack to slip into pseudo-enforcement of the "all headers are in the first View" invariant. Removing them and replacing with PullUp(n) breaks this reliance and will make it easier to add iptables support and rework network buffer management. The new View.PullUp(n) method is low cost in the common case, when when all the headers fit in the first View. PiperOrigin-RevId: 308163542

2019-10-22netstack/tcp: software segmentation offloadAndrei Vagin
Right now, we send each tcp packet separately, we call one system call per-packet. This patch allows to generate multiple tcp packets and send them by sendmmsg. The arguable part of this CL is a way how to handle multiple headers. This CL adds the next field to the Prepandable buffer.
