2020-11-02[vfs2] Refactor kernfs checkCreateLocked.Dean Deng
Don't return the filename, since it can already be determined by the caller. This was causing a panic in RenameAt, which relied on the name to be nonempty even if the error was EEXIST. Reported-by: syzbot+e9f117d000301e42361f@syzkaller.appspotmail.com PiperOrigin-RevId: 340381946

2020-11-02Send NUD probes in a separate gorountineSam Balana
Send NUD probes in another gorountine to free the thread of execution for finishing the state transition. This is necessary to avoid deadlock where sending and processing probes are done in the same call stack, such as loopback and integration tests. Fixes #4701 PiperOrigin-RevId: 340362481

2020-10-31net/tcpip: connect to unset loopback address has to return EADDRNOTAVAILAndrei Vagin
In the docker container, the ipv6 loopback address is not set, and connect("::1") has to return ENEADDRNOTAVAIL in this case. Without this fix, it returns EHOSTUNREACH. PiperOrigin-RevId: 340002915

2020-10-30Separate kernel.Task.AsCopyContext() into CopyContext() and OwnCopyContext().Jamie Liu
kernel.copyContext{t} cannot be used outside of t's task goroutine, for three reasons: - t.CopyScratchBuffer() is task-goroutine-local. - Calling t.MemoryManager() without running on t's task goroutine or locking t.mu violates t.MemoryManager()'s preconditions. - kernel.copyContext passes t as context.Context to MM IO methods, which is illegal outside of t's task goroutine (cf. kernel.Task.Value()). Fix this by splitting AsCopyContext() into CopyContext() (which takes an explicit context.Context and is usable outside of the task goroutine) and OwnCopyContext() (which uses t as context.Context, but is only usable by t's task goroutine).

2020-10-29Delay goroutine creation during TCP handshake for accept/connect.Dean Deng
Refactor TCP handshake code so that when connect is initiated, the initial SYN is sent before creating a goroutine to handle the rest of the handshake (which blocks). Similarly, the initial SYN-ACK is sent inline when SYN is received during accept. Some additional cleanup is done as well. Eventually we would like to complete connections in the dispatcher without requiring a wakeup to complete the handshake. This refactor makes that easier. Updates #231 PiperOrigin-RevId: 339675182
