Subject: [PATCH v2 4/5] eventdev/crypto: fix overflow in circular buffer
Date: Thu, 1 Dec 2022 00:46:51 -0600 [thread overview]
Message-ID: <20221201064652.1885734-4-ganapati.kundapura@intel.com> (raw)
In-Reply-To: <20221201064652.1885734-1-ganapati.kundapura@intel.com>
Crypto adapter checks CPM backpressure once in enq_run()
This leads to buffer overflow if some ops failed to flush
to cryptodev.
Checked CPM backpressure for every iteration in enq_run()
Fixes: 7901eac3409a ("eventdev: add crypto adapter implementation")
