Subject: mask mode issues

Sayantan,
I am getting crashes when mask is invalid, maybe some kind of
validation can help to avoid that.

ukasz@...l:$ ./john -mask='?a?a?a' crackme -format=raw-md5-opencl
Device 2: GeForce GTX TITAN
Local worksize (LWS) 64, global worksize (GWS) 2097152
Loaded 1 password hash (Raw-MD5-opencl [MD5 OpenCL (inefficient,
development use only)])
Press 'q' or Ctrl-C to abort, almost any other key for status

START:

(...x14)

START:
Segmentation fault (core dumped)


ukasz@...l:$ ./john -mask=openwall crackme -format=raw-sha1-opencl
(...)
Segmentation fault (core dumped)

Also your changes broke other modes and this is unacceptable:
ukasz@...l:$ ./john -i crackme -format=raw-sha1-opencl
Device 2: GeForce GTX TITAN
Local worksize (LWS) 512, Global worksize (GWS) 2097152
Loaded 1 password hash (Raw-SHA1-opencl [SHA1 OpenCL (inefficient,
development use only)])
New local worksize (LWS) 64
Press 'q' or Ctrl-C to abort, almost any other key for status
No given mask.Exiting...


ukasz@...l:$ ./john -w crackme -format=raw-sha1-opencl
(...)
No given mask.Exiting...
