Subject: [PATCH 0/2] fix parsing of reboot= cmdline
Date: Fri, 16 Oct 2020 20:09:05 +0200 [thread overview]
Message-ID: <20201016180907.171957-1-mcroce@linux.microsoft.com> (raw)
From: Matteo Croce <mcroce@microsoft.com>
The parsing of the reboot= cmdline has two major errors:
- a missing bound check can crash the system on reboot
- parsing of the cpu number only works if specified last
Fix both, along with a small code refactor.
Matteo Croce (2):
reboot: fix overflow parsing reboot cpu number
reboot: fix parsing of reboot cpu number
