This was adjusted to accept all non-zero values (while now rejecting zero) in commit 53642399aa71 ("usb: gadget: f_fs: Fix wrong check on reserved1 of OS_DESC_EXT_COMPAT"), but that breaks any userspace programs that worked previously by returning EINVAL when Reserved1 == 0 which was previously the only value that succeeded! If we just set the field to "1" ourselves, both old and new userspace programs continue to work correctly and, as a bonus, old programs are now compliant with the specification without having to fix anything themselves.

[Linux-stable-mirror] Patch "locking/refcounts: Do not force refcount_t usage as GPL-only export" has been added to the 4.14-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled locking/refcounts: Do not force refcount_t usage as GPL-only export to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: locking-refcounts-do-not-force-refcount_t-usage-as-gpl-only-export.patch and it can be found in the queue-4.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From b562c171cf011d297059bd0265742eb5fab0ad2f Mon Sep 17 00:00:00 2001 From: Kees Cook <keescook(a)chromium.org> Date: Mon, 4 Dec 2017 17:24:54 -0800 Subject: locking/refcounts: Do not force refcount_t usage as GPL-only export From: Kees Cook <keescook(a)chromium.org> commit b562c171cf011d297059bd0265742eb5fab0ad2f upstream. The refcount_t protection on x86 was not intended to use the stricter GPL export. This adjusts the linkage again to avoid a regression in the availability of the refcount API.
