* Convert an IPv4 or IPv6 IP range to an array of subnets which can contain the range.
|
|
522
|
* Algorithm and embodying code PD'ed by Stilez - enjoy as you like :-)
|
|
523
|
*
|
|
524
|
* Documented on pfsense dev list 19-20 May 2013. Summary:
|
|
525
|
*
|
|
526
|
* The algorithm looks at patterns of 0's and 1's in the least significant bit(s), whether IPv4 or IPv6.
|
|
527
|
* These are all that needs checking to identify a _guaranteed_ correct, minimal and optimal subnet array.
|
|
528
|
*
|
|
529
|
* As a result, string/binary pattern matching of the binary IP is very efficient. It uses just 2 pattern-matching rules
|
|
530
|
* to chop off increasingly larger subnets at both ends that can't be part of larger subnets, until nothing's left.
|
|
531
|
*
|
|
532
|
* (a) If any range has EITHER low bit 1 (in startip) or 0 (in endip), that end-point is _always guaranteed_ to be optimally
|
|
533
|
* represented by its own 'single IP' CIDR; the remaining range then shrinks by one IP up or down, causing the new end-point's
|
|
534
|
* low bit to change from 1->0 (startip) or 0->1 (endip). Only one edge case needs checking: if a range contains exactly 2
|
|
535
|
* adjacent IPs of this format, then the two IPs themselves are required to span it, and we're done.
|
|
536
|
* Once this rule is applied, the remaining range is _guaranteed_ to end in 0's and 1's so rule (b) can now be used, and its
|
|
537
|
* low bits can now be ignored.
|
|
538
|
*
|
|
539
|
* (b) If any range has BOTH startip and endip ending in some number of 0's and 1's respectively, these low bits can
|
|
540
|
* *always* be ignored and "bit-shifted" for subnet spanning. So provided we remember the bits we've place-shifted, we can
|
|
541
|
* _always_ right-shift and chop off those bits, leaving a smaller range that has EITHER startip ending in 1 or endip ending
|
|
542
|
* in 0 (ie can now apply (a) again) or the entire range has vanished and we're done.
|
|
543
|
* We then loop to redo (a) again on the remaining (place shifted) range until after a few loops, the remaining (place shifted)
|
|
544
|
* range 'vanishes' by meeting the exit criteria of (a) or (b), and we're done.

|

3210
|
* a) For DUID-LLT and DUID-EN, convert the time/enterprise ID input to hex and append the link-layer address/identifier input.
|
|
3211
|
* b) For DUID-LLT and DUID-LL, prepend a hardware type of 1.
|
|
3212
|
* c) For DUID-UUID, remove any "-".
|
|
3213
|
* 2) Replace any remaining "-" with ":".
|
|
3214
|
* 3) If any components are input with just a single char (hex digit hopefully), put a "0" in front.
|
|
3215
|
* 4) The first two components should be a 16-bit integer (little- or big-endian, depending on the current machine type) that
|
|
3216
|
* is equal to the number of other components. If not, prepend this as "nn:00" (all pfSense builds are little-endian).
|
