staging: dgrp: check return value of alloc_tty_driver

2012-10-17T21:10:10+00:00

alloc_tty_driver was always assumed to succeed.  Add code to check the
return value and return -ENOMEM if alloc_tty_driver fails.

staging: dgrp: check for NULL pointer in (un)register_proc_table

2012-10-17T21:10:10+00:00

register_proc_table and unregister_proc_table didn't deal with the
possibility that the *table pointer could be NULL.  Check for this and
return if table is NULL.

userns: Fix build of drivers/staging/dgrp

2012-10-03T16:52:08+00:00

Explicitly test for GLOBAL_ROOT_UID and GLOBAL_ROOT_GID
instead of using 0, allowing dgrp to compile and work
properly when user namespace support is enabled.

staging: dgrp: fix potential call to strncpy with a negative number

2012-09-25T22:42:38+00:00

In dgrp_receive() there is:

   desclen = ((plen - 12) > MAX_DESC_LEN) ? MAX_DESC_LEN :
   	     	      	    plen - 12;
   strncpy(nd->nd_ps_desc, b + 12, desclen);

However, it's possible for plen to be <= 12 here so we'd be passing a
negative number into the strncpy().  Fix this to not make the strncpy
call and report an error if desclen is <= 0
