[ Upstream commit4a46fdba44] afs_deliver_vl_get_entry_by_name_u() scans through the vl entry received from the volume location server and builds a return list containing the sites that are currently valid. When assigning values for the return list, the index into the vl entry (i) is used rather than the one for the new list (entry->nr_server). If all sites are usable, this works out fine as the indices will match. If some sites are not valid, for example if AFS_VLSF_DONTUSE is set, fs_mask and the uuid will be set for the wrong return site. Fix this by using entry->nr_server as the index into the arrays being filled in rather than i. This can lead to EDESTADDRREQ errors if none of the returned sites have a valid fs_mask.

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.
