Subject: Re: [PATCH] RDMA/irdma: Free IRQ when CEQ vector mapping fails
Date: Fri, 18 Sep 2026 11:15:10 +0000 [thread overview]
Message-ID: <20260918111510.DF23B1F000FF@smtp.kernel.org> (raw)
In-Reply-To: <20260918110428.36586-1-serhatkumral1@gmail.com>
> irdma_cfg_ceq_vector() registers an IRQ handler before requesting the
> CEQ-to-vector mapping through the virtual channel. If the mapping
> fails, the function returns without releasing the IRQ resources.
> The caller destroys the CEQ, leaving the IRQ handler registered
> and potentially referencing freed memory.
>
> Call irdma_destroy_irq() on mapping failure to release
> the IRQ resources and drain the associated tasklet
> before the caller destroys the CEQ. Use the same dev_id
> passed to request_irq(), accounting for CEQ0 sharing
> its interrupt vector with the AEQ.
