Subject: Re: [PATCH v5 8/8] s390/crypto: Map EBUSY to EIO when key conversion fails repeatedly
Date: Thu, 20 Aug 2026 14:32:50 +0000 [thread overview]
Message-ID: <20260820143250.B3A621F00A3D@smtp.kernel.org> (raw)
In-Reply-To: <20260820141957.19091-9-freude@linux.ibm.com>
> When hardware persistently returns -EBUSY after exhausting retries,
> the error propagates to crypto_finalize_*_request(). The crypto API's
> completion wrapper treats -EBUSY as a queueing status and swallows it,
> preventing the completion callback from firing. This causes callers
> using crypto_wait_req() to block indefinitely.
>
> Translate persistent -EBUSY to -EIO after retry exhaustion to ensure
> proper error propagation and callback invocation.

> Signed-off-by: Harald Freudenberger <freude@linux.ibm.com>
