Hello,

syzbot has tested the proposed patch and the reproducer did not trigger any issue:

Reported-and-tested-by: syzbot+f44badb06036334e867a@xxxxxxxxxxxxxxxxxxxxxxxxx

So it looks like you were right. But maybe ret < sizeof(smsr) would be

I agree, this looks much cleaner.

Also, the bug you mentioned in previous email is also real, so I will prepare a patch series if you haven't fixed it by yourself :)



With regards,
