Subject: [PATCH 0/2] nilfs2: fix UBSAN shift-out-of-bounds warnings on mount time
Date: Thu, 27 Oct 2022 13:43:04 +0900	[thread overview]
Message-ID: <20221027044306.42774-1-konishi.ryusuke@gmail.com> (raw)

Hi Andrew,

please apply the following bug fixes to -mm tree:

Ryusuke Konishi (2):
  nilfs2: fix shift-out-of-bounds/overflow in nilfs_sb2_bad_offset()
  nilfs2: fix shift-out-of-bounds due to too large exponent of block
    size

The first patch fixes a reported bug by syzbot, and the second one
fixes the remaining bug of the same kind.  Although they are triggered
by the same super block data anomaly, I divided it into the above two
because the details of the issues and how to fix it are different.

Both are required to eliminate the shift-out-of-bounds issues on mount time.

Thanks,
Ryusuke Konishi
