* fbdev: color map copying bounds checkingKees Cook2017-02-01
| | | | | | | | | | | | | | | | | | | | | | commit 2dc705a9930b4806250fbf5a76e55266e59389f2 upstream. Copying color maps to userspace doesn't check the value of to->start, which will cause kernel heap buffer OOB read due to signedness wraps.

* fbdev: move fbdev core files to separate directoryTomi Valkeinen2014-04-17
Instead of having fbdev framework core files at the root fbdev directory, mixed with random fbdev device drivers, move the fbdev core files to a separate core directory. This makes it much clearer which of the files are actually part of the fbdev framework, and which are part of device drivers.
