|
|
* static int filecore_checksum(u_char *bootblock)
|
|
*
|
|
* Calculates the filecore boot block checksum. This is used to validate
|
|
* a filecore boot block on the disk. If a boot block is validated then
|
|
* it is used to locate the partition table. If the boot block is not
|
|
* validated, it is assumed that the whole disk is NetBSD.
|
|
*
|
|
* The basic algorithm is:
|
|
*
|
|
* for (each byte in block, excluding checksum) {
|
|
* sum += byte;
|
|
* if (sum > 255)
|
|
* sum -= 255;
|
|
* }
|
|
*
|
|
* That's equivalent to summing all of the bytes in the block
|
|
* (excluding the checksum byte, of course), then calculating the
|
|
* checksum as "cksum = sum - ((sum - 1) / 255) * 255)". That
|
|
* expression may or may not yield a faster checksum function,
|
|
* but it's easier to reason about.
|
|
*
|
|
* Note that if you have a block filled with bytes of a single
|
|
* value "X" (regardless of that value!) and calculate the cksum
|
|
* of the block (excluding the checksum byte), you will _always_
|
|
* end up with a checksum of X. (Do the math; that can be derived
|
|
* from the checksum calculation function!) That means that
|
|
* blocks which contain bytes which all have the same value will
|
|
* always checksum properly. That's a _very_ unlikely occurence
|
|
* (probably impossible, actually) for a valid filecore boot block,
|
|
* so we treat such blocks as invalid.
