Subject: [PATCH 0/2] vhost: fix ranges when call vhost_iotlb_itree_first()
Date: Tue, 8 Nov 2022 11:34:35 +0100 [thread overview]
Message-ID: <20221108103437.105327-1-sgarzare@redhat.com> (raw)
While I was working on vringh to support VA in vringh_*_iotlb()
I saw that the range we use in iotlb_translate() when we call
vhost_iotlb_itree_first() was not correct IIUC.
So I looked at all the calls and found that in vhost.c as well.
I didn't observe a failure and I don't have a reproducer because
I noticed the problem by looking at the code.
Maybe we didn't have a problem, because a shorter range was being
returned anyway and the loop stopped taking into account the total
amount of bytes translated, but I think it's better to fix.
Thanks,
Stefano
