J. Bruce Fields f9304c6277 sunrpc: safely reallow resvport min/max inversion [ Upstream commit `826799e66e` ] Commits `ffb6ca33b0` and `e08ea3a96f` prevent setting xprt_min_resvport greater than xprt_max_resvport, but may also break simple code that sets one parameter then the other, if the new range does not overlap the old. Also it looks racy to me, unless there's some serialization I'm not seeing. Granted it would probably require malicious privileged processes (unless there's a chance these might eventually be settable in unprivileged containers), but still it seems better not to let userspace panic the kernel. Simpler seems to be to allow setting the parameters to whatever you want but interpret xprt_min_resvport > xprt_max_resvport as the empty range.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
