Summary
nilfs2: propagate directory read errors from nilfs_find_entry()
Details

In the Linux kernel, the following vulnerability has been resolved:

nilfs2: propagate directory read errors from nilfsfindentry()

Syzbot reported that a task hang occurs in vcs_open() during a fuzzing test for nilfs2.

The root cause of this problem is that in nilfsfindentry(), which searches for directory entries, ignores errors when loading a directory page/folio via nilfsgetfolio() fails.

If the filesystem images is corrupted, and the isize of the directory inode is large, and the directory page/folio is successfully read but fails the sanity check, for example when it is zero-filled, nilfscheck_folio() may continue to spit out error messages in bursts.

Fix this issue by propagating the error to the callers when loading a page/folio fails in nilfsfindentry().

The current interface of nilfsfindentry() and its callers is outdated and cannot propagate error codes such as -EIO and -ENOMEM returned via nilfsfindentry(), so fix it together.
