Is this issue got fixed on any latest kernel ? if so, can you please
help point the patch ?
If not got fixed, can we have a final solution ? i can even help in
testing the solution.
Hi John,
Hi Bart,
Some time ago you replied the following to an email from me with a
suggestion for a fix: "Please let me consider it a bit more." Are you
still working on a fix?
Unfortunately I have not had a chance, sorry. But I can look again.
So I have only seen KASAN use-after-free's myself, but never an actual
oops. IIRC, someone did report an oops.
@Pradeep, do you have a reliable re-creator? I noticed the timeout
handler stackframe in your mail, so I guess not. However, as an
experiment, could you test:
https://lore.kernel.org/linux-block/1608203273-170555-2-git-send-email-john.garry@xxxxxxxxxx/
This should fix the common issue. But no final solution to issues
discussed from patch 2/2, which is more exotic.
BTW, is this the same Pradeep who reported:
https://lore.kernel.org/linux-block/1606402925-24420-1-git-send-email-ppvk@xxxxxxxxxxxxxx/
I did cc ppvk@xxxxxxxxxxxxxx on earlier version of my series, but it
bounced.
