Subject: Re: [PATCH] ext4: validate extent entries before caching in ext4_find_extent()
Date: Mon, 29 Sep 2025 21:15:48 +0530	[thread overview]
Message-ID: <20250929154548.360371-1-kartikey406@gmail.com> (raw)

Zhang Yi,

I've prepared v2 based on your feedback about avoiding redundant checks. 
After further analysis, I'm detecting the invalid INLINE_DATA + EXTENTS 
flag combination rather than just VERITY + INLINE_DATA, as this addresses 
the broader issue of mutually exclusive flags.

The v2 patch rejects any inode with both INLINE_DATA and EXTENTS flags set,
which catches this corruption and potentially other similar cases.

Thank you for guiding me to the root cause.

Best regards,
Deepanshu
