[PATCH] exports: document change to "insecure" export option

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: "J. Bruce Fields" <bfields@xxxxxxxxxx>

We're changing the kernel to allow gss requests from high ports even
when "secure" is set.

If the change gets backported to distro kernels, the kernel version may
be an imperfect predictor of the behavior, but I think it's the best we
can do.
