From: Matteo Croce <[email protected]> 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. v2->v3: Revert the offending commit first, then fix the other bug. CC stable v1->v2: As Petr suggested, don't force base 10 in simple_strtoul(), so hex values are accepted as well. Matteo Croce (3): Revert "kernel/reboot.c: convert simple_strtoul to kstrtoint" reboot: fix overflow parsing reboot cpu number reboot: refactor and comment the cpu selection code kernel/reboot.c | 30 +++++++++++++++++------------- 1 file changed, 17 insertions(+), 13 deletions(-) -- 2.28.0
