The NFSv4.1 (and 4.2 on 13) server incorrectly binds a new TCP connection to the back channel when first used by an RPC with a Sequence op in it (almost all of them). RFC5661 specifies that only the fore channel should be bound. This was done because early clients (including FreeBSD) did not do the required BindConnectionToSession RPC. Unfortunately, this breaks the Linux client when the "nconnects" mount option is used, since the server may do a callback on the incorrect TCP connection. This patch converts the server behaviour to that required by the RFC. It also makes the server test/indicate failure of the back channel more aggressively. Until this patch is applied to the server, the "nconnects" mount option is not recommended for a Linux NFSv4.1/4.2 client mount to the FreeBSD server.

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.
