commit f0992098ca upstream.
Speakup exposing a line discipline allows userland to try to use it,
while it is deemed to be useless, and thus uselessly exposes potential
bugs. One of them is simply that in such a case if the line sends data,
spk_ttyio_receive_buf2 is called and crashes since spk_ttyio_synth
is NULL.
This change restricts the use of the speakup line discipline to
speakup drivers, thus avoiding such kind of issues altogether.

commit d412275444 upstream.
Speakup has only one speakup_tty variable to store the tty it is managing. This
makes sense since its codebase currently assumes that there is only one user who
controls the screen reading.
That however means that we have to forbid using the line discipline several
times, otherwise the second closure would try to free a NULL ldisc_data, leading to

We need to nest the console lock in sel_lock, so we have to push it down

This patch replaces speakup's implementations with calls to functions
in tty/vt/selection.c. Those functions are:
cancel_selection()
set_selection_kernel()
paste_selection()
Currently setting selection is done in interrupt context. However,
set_selection_kernel() can sleep - for instance, it requires console_lock
which can sleep. Therefore we offload that work to a work_struct thread,
following the same pattern which was already set for paste_selection().
When setting selection, we also get a reference to tty and make sure to
release the reference before returning.
struct speakup_paste_work has been renamed to the more generic
speakup_selection_work because it is now used for both pasting as well
as setting selection. When paste work is cancelled, the code wasn't
setting tty to NULL. This patch also fixes that by setting tty to NULL
so that in case of failure we don't get EBUSY forever.

When switching from speakup_soft to another synth, speakup_soft would
keep calling synth_buffer_getc() from softsynthx_read.
Let's thus make synth.c export the knowledge of the current synth, so
that speakup_soft can determine whether it should be running.
speakup_soft also needs to set itself alive, otherwise the switch would
let it remain silent.

Here is the big set of Staging/IIO driver patches for 4.17-rc1.
It is a lot, over 500 changes, but not huge by previous kernel release
standards. We deleted more lines than we added again (27k added vs. 91k
remvoed), thanks to finally being able to delete the IRDA drivers and
networking code.
We also deleted the ccree crypto driver, but that's coming back in
through the crypto tree to you, in a much cleaned-up form.
Added this round is at lot of "mt7621" device support, which is for an
embedded device that Neil Brown cares about, and of course a handful of
new IIO drivers as well.
And finally, the fsl-mc core code moved out of the staging tree to the

L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
done
with de-mangling cleanups yet to come.
NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do. But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.
The next patch from Al will sort out the final differences, and we
should be all done.

Now that the SPDX tag is in all drivers/staging/speakup/ files, that
identifies the license in a specific and legally-defined manner. So the
extra GPL text wording can be removed as it is no longer needed at all.
This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text. And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.
No copyright headers or other non-license-description text was removed.

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.
Fix up the remaining staging speakup files to have a proper SPDX
identifier, based on the license text in the file itself. The SPDX
identifier is a legally binding shorthand, which can be used instead of
the full boiler plate text.
