Al Viro 6a029a90f5 [PATCH] mmaper_kern.c fixes [buffer overruns] ... - copy_from_user() can fail; ->write() must check its return value. - severe buffer overruns both in ->read() and ->write() - lseek to the end (i.e. to mmapper_size) and if (count + *ppos > mmapper_size) count = count + *ppos - mmapper_size; will do absolutely nothing. Then it will call copy_to_user(buf,&v_buf[*ppos],count); with obvious results (similar for ->write()). Fixed by turning read to simple_read_from_buffer() and by doing normal limiting of count in ->write(). - gratitious lock_kernel() in ->mmap() - it's useless there. - lots of gratuitous includes.
