uiomove() leaves an iovec it has just emptied as the current one, so cuse_client_read() and cuse_client_write() picked it up again on the next iteration, sent the server a zero-length command, and got zero bytes back. That left the residual count unchanged, so the loop never terminated and the call never returned. Step past empty iovecs at the start of every iteration. This also covers caller-supplied zero-length iovecs, which hung in the same way PR: 293489 MFC after: 1 week Sponsored by: The FreeBSD Foundation Reviewed by: kib, markj Differential Revision: https://reviews.freebsd.org/D59822
FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
