2020-11-09Skip `EventHUp` notify in `FIN_WAIT2` on a socket close.Mithun Iyer
This Notify was added as part of cl/279106406; but notifying `EventHUp` in `FIN_WAIT2` is incorrect, as we want to only notify later on `TIME_WAIT` or a reset. However, we do need to notify any blocked waiters of an activity on the endpoint with `EventIn`|`EventOut`. PiperOrigin-RevId: 341490913

2020-11-09Initialize references with a value of 1.Dean Deng
This lets us avoid treating a value of 0 as one reference. All references using the refsvfs2 template must call InitRefs() before the reference is incremented/decremented, or else a panic will occur. Therefore, it should be pretty easy to identify missing InitRef calls during testing. Updates #1486. PiperOrigin-RevId: 341411151

2020-11-06[vfs] overlayfs: Do not unlink non-existing whiteout during file creation.Ayush Ranjan
We can reuse information about whether a whiteout exists on a given file path from stepLocked when creating a file at that path. This helps save an Unlink call to the upper filesystem if the whiteout does NOT exist (common case). Plumbs this information from lookupLocked() -> getChildLocked() -> stepLocked(). This also helped save a Lookup in RenameAt(). Fixes #1199 PiperOrigin-RevId: 341105351

2020-11-06Fix infinite loop when splicing to pipes/eventfds.Nicolas Lacasse
Writes to pipes of size < PIPE_BUF are guaranteed to be atomic, so writes larger than that will return EAGAIN if the pipe has capacity < PIPE_BUF. Writes to eventfds will return EAGAIN if the write would cause the eventfd value to go over the max. In both such cases, calling Ready() on the FD will return true (because it is possible to write), but specific kinds of writes will in fact return EAGAIN. This CL fixes an infinite loop in splice and sendfile (VFS1 and VFS2) by forcing skipping the readiness check for the outfile in send, splice, and tee. PiperOrigin-RevId: 341102260
