staging: speakup: fix wraparound in uaccess length check

2018-07-16T08:04:11+00:00

If softsynthx_read() is called with `count < 3`, `count - 3` wraps, causing
the loop to copy as much data as available to the provided buffer. If
softsynthx_read() is invoked through sys_splice(), this causes an
unbounded kernel write; but even when userspace just reads from it
normally, a small size could cause userspace crashes.

staging: speakup: remove redundant variable l

2018-07-11T12:45:54+00:00

Variable l is being assigned but is never used hence it is redundant
and can be removed.

Cleans up clang warning:
warning: variable 'l' set but not used [-Wunused-but-set-variable

staging: speakup: Replace strncpy with memcpy

2018-07-02T08:39:06+00:00

gcc 8.1.0 generates the following warnings.

drivers/staging/speakup/kobjects.c: In function 'punc_store':
drivers/staging/speakup/kobjects.c:522:2: warning:
	'strncpy' output truncated before terminating nul
	copying as many bytes from a string as its length
drivers/staging/speakup/kobjects.c:504:6: note: length computed here

drivers/staging/speakup/kobjects.c: In function 'synth_store':
drivers/staging/speakup/kobjects.c:391:2: warning:
	'strncpy' output truncated before terminating nul
	copying as many bytes from a string as its length
drivers/staging/speakup/kobjects.c:388:8: note: length computed here

Using strncpy() is indeed less than perfect since the length of data to
be copied has already been determined with strlen(). Replace strncpy()
with memcpy() to address the warning and optimize the code a little.

staging: speakup: refactor synths array to use a list

2018-06-17T07:05:11+00:00

The synths[] array is a collection of synths acting like a list.
There is no need for synths to be an array, so refactor synths[] to use
standard kernel list_head API, instead, and modify the usages to suit.
As a side-effect, the maximum number of synths has also become redundant.

staging: speakup: Add pause command used on switching to graphical mode

2018-05-07T02:02:37+00:00

For software speech syntheses to be able to manage concurrent audio card
access, they need to know when speakup stops emitting text to be spoken
because the console has switched to graphical mode.  This introduces a
PAUSE command to do so.

Merge tag 'staging-4.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

2018-04-05T01:56:27+00:00

Pull staging/IIO updates from Greg KH:
 "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
  "real" part of the kernel, which is nice to see happen as well.

  Full details are in the shortlog, which has all of the tiny cleanup
  patches described.

  All of these have been in linux-next for a while with no reported
  issues"
