Enhance getuint64() to take a minimum value as ask_num() does. Use this to ensure that GPT partitions are constrained to the valid area of the disk. Leave MBR partition constraints alone for the moment. Original problem(s) noted by tim@ Avoid problems with pathological input during edit operations. i.e. never 2015-11-12T15:07:41Z krw krw@openbsd.org 2015-11-12T15:07:41Z urn:sha1:72070960b809a8c0e77907ab82f1e22c27fc3fdf attempt to use data past the end of the input. Since the return value of ask_cmd() is never checked, make it void instead of int. Problems found, original diff from and ok tim@. Add GPT editing. Based on GSOC 2014 work by Markus Muller. 2015-10-26T15:08:26Z krw krw@openbsd.org 2015-10-26T15:08:26Z urn:sha1:fba7235c8f065143ebcde5dd90e0f7eb8ce85042 Even better -- readsector() and writesector() become DISK_readsector() and 2015-03-30T17:11:49Z krw krw@openbsd.org 2015-03-30T17:11:49Z urn:sha1:c2348643a1a77b3807efc59b8fa3beeea7080886 DISK_writesector() and live in disk.[ch].

Tweak ask_pid() to take low/high bounds so it can handle 1-ff (MBR) or 1000-ffff (GPT) partition pids as required. A pid of '0' is still special and disables the partition.

Fewer parameters, less confusion, no functional change.
