Mike Christie a3ecee8a8f scsi: target: Fix alua_tg_pt_gps_count tracking
[ Upstream commit 1283c0d1a32bb924324481586b5d6e8e76f676ba ]

We can't free the tg_pt_gp in core_alua_set_tg_pt_gp_id() because it's
still accessed via configfs. Its release must go through the normal
configfs/refcount process.

The max alua_tg_pt_gps_count check should probably have been done in
core_alua_allocate_tg_pt_gp(), but with the current code userspace could
have created 0x0000ffff + 1 groups, but only set the id for 0x0000ffff.
Then it could have deleted a group with an ID set, and then set the ID for
that extra group and it would work ok.

It's unlikely, but just in case this patch continues to allow that type of
behavior, and just fixes the kfree() while in use bug.

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.

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.
