Subject: Re: [PATCH] vhost/vringh: reject zero-length indirect descriptor tables
Date: Tue,  3 Nov 2026 22:29:32 +0800	[thread overview]
Message-ID: <20261103142932.65745-1-fangxy@xiaopeng.com> (raw)

Hi Michael,

Thanks. I checked the applied v2 (60a792b97933) in your
vhost branch and it looks good.

One small thing on top of it: vringh_bad() there still
passes the raw desc->len, so the reported length reads
wrong when the vring byte order differs from the CPU
byte order. The October 21 posting had this right; the
rest is fine as is.

Happy to send a one-line follow-up on top of your branch
if you want it; otherwise fine to leave as is.

Thanks,
Fang
