Subject: RE: [PATCH v3] net/netvsc: fix number Tx queues > Rx queues
Date: Tue, 19 Mar 2024 18:40:28 +0000 [thread overview]
Message-ID: <SJ1PR21MB3457AB08E30BFA918A159028CE2C2@SJ1PR21MB3457.namprd21.prod.outlook.com> (raw)

> Subject: [PATCH v3] net/netvsc: fix number Tx queues > Rx queues
>
> The previous code allowed the number of Tx queues to be set higher than the
> number of Rx queues. If a packet was sent on a Tx queue with index
> >= number Rx queues there was a segfault.
>
> This commit fixes the issue by creating an Rx queue for every Tx queue meaning
> that an event buffer is allocated to handle receiving Tx completion messages.
>
> mbuf pool and Rx ring are not allocated for these additional Rx queues and RSS
> configuration ensures that no packets are received on them.
>
> Fixes: 4e9c73e96e83 ("net/netvsc: add Hyper-V network device")
