[PATCH 0/2] nilfs2: robustness fixes from Jake Labelle
From: Ryusuke Konishi
Date: Thu Oct 08 2026 - 07:56:17 EST
Hi Viacheslav,
Please add the following two commits from Jake Labelle to your queue
for the next cycle.
As this cycle is getting closer to its end, I am sending these ahead with
a minor fix applied. If Jake responds with further comments or revised
proposals later, we can discuss them as needed.
These patches address two robustness issues:
- Patch 1/2 rejects special inodes during dsync recovery to prevent
dereferencing uninitialized bmap function pointers.
- Patch 2/2 validates and snaps the directory position after llseek in
nilfs_readdir() to prevent invalid or out-of-bounds page reads.
For full context and background details, please refer to the original
cover letter here:

Thanks,
Ryusuke Konishi
