Important EXT4 problem in kernel 6.1.64 (and maybe others)

[Kobold]

When i look at the developer mails, it looks to me that 6.5 was also affected…

Im still pretty lost here…

[MrLavender]

The bug was only present in release candidate versions of later kernels (specifically 6.5-rc1). See comments here - Ext4 data corruption in stable kernels [LWN.net]

@opx

“hidden” data corruption because of a Cryptomator low level bug a while ago

What is a Cryptomator low level bug?

Is this something related with luks?

[silverhikari]

so as long as you weren’t using 6.5-rcs or 6.1 before the recent fix you are safe?

[MrLavender]

Correct (and anyone who runs a release candidate kernel on a production system doesn’t get to complain about bugs ).

@MrLavender

anyone who runs a release candidate kernel on a production system doesn’t get to complain about bugs

So me as a 6.1 LTSC User, have the full right to complain

Yeah It doesn’t look good that a cherry-picked commit from a rc kernel was back-ported to a stable LTS kernel…

@ All
Is this data loss also connected, when i copy a clean file from ext4 and paste it to a exfat Partition?

That this file having a chance of getting corrupted in the copy progress? In the E-Mails the descriptions only looks vice versa, sample: copy a exfat file to ext4 partition. Right?

And what can happend, when i copy a corrupt ext4 file on a exfat partition?
Is there a chance, that my whole exfat partition getting destroyed after time?

Im worrying about my backup exfat drives

No. It happens only when writing to ext4.

@Kobold

Then you’ve got a corrupted file and a copy of that corrupted file.

@Kobold

Is there a chance, that my whole exfat partition getting destroyed after time?

Not from that, no. But 5 billion years from now, Earth will be consumed by the sun, and I suspect that your exfat drive won’t survive that.

For Game & Ext4 users:

You don’t know if there are corrupted games on Steam, Steam has the ability to check games with checksum and fix them.

Select any installed/updated game → Right click on game to open menu → properties → Installed Files → Verify integrity of game files

The bug is supposedly fixed now right?

I updated BG3 yesterday with 25ish GB, my partition (ext4) during the process became almost full (12GB free), then when download and install process was done, 130GB free. Makes zero sense. I just cross my fingers that my games work, I haven’t tried them all.
