Kazutaka YOKOTA 38c6184fd5 Reject unreasonable values passed to CONS_HISTORY ioctl. It did not ... check the value and caused kernel panic when a large value was given. - Move the configuration option SC_HISTORY_SIZE from syscons.h to syscons.c. - Define the maximum total number of history lines of all consoles. It is SC_HISTORY_SIZE*MAXCONS or 1000*MAXCONS; whichever is larger. CONS_HISTORY will allow the user to set the history size up to SC_HISTORY_SIZE unconditionally (or the current height of the console if it is larger than SC_HISTORY_SIZE). If the user requests a larger buffer, it will be granted only if the total number of all allocated history lines and the requested number of lines won't exceed the maximum. - Don't free the previous history buffer and leave the history buffer pointer holding a invalid pointer. Set the pointer to NULL first, then free the buffer. PR: bin/4592		1997-10-23 03:23:50 +00:00
