Subject: [PATCH 0/7] ext4: avoid sysfs variables overflow causing BUG_ON/SOOB
Date: Fri, 26 Jan 2024 16:57:09 +0800 [thread overview]
Message-ID: <20240126085716.1363019-1-libaokun1@huawei.com> (raw)
Hello everyone,
This patchset is intended to avoid variables that can be modified via sysfs
from overflowing when stored or used and thus causing various problems.
"kvm-xfstests -c ext4/all -g auto" has been executed with no new failures.
Baokun Li (7):
ext4: avoid overflow when setting values via sysfs
ext4: refactor out ext4_generic_attr_store()
ext4: refactor out ext4_generic_attr_show()
ext4: add positive int attr pointer to avoid sysfs variables overflow
ext4: fix slab-out-of-bounds in
ext4_mb_find_good_group_avg_frag_lists()
ext4: set type of ac_groups_linear_remaining to __u32 to avoid
overflow
ext4: set the type of max_zeroout to unsigned int to avoid overflow
