> Subject: [PATCH v3 1/2] security: add fallback security processing and Rx > inject > > Add alternate datapath API for security processing which would do Rx > injection (similar to loopback) after successful security processing. > > With inline protocol offload, variable part of the session context > (AR windows, lifetime etc in case of IPsec), is not accessible to the > application. If packets are not getting processed in the inline path > due to non security reasons (such as outer fragmentation or rte_flow > packet steering limitations), then the packet cannot be security > processed as the session context is private to the PMD and security > library doesn't provide alternate APIs to make use of the same session. > > Introduce new API and Rx injection as fallback mechanism to security > processing failures due to non-security reasons. For example, when there > is outer fragmentation and PMD doesn't support reassembly of outer > fragments, application would receive fragments which it can then > reassemble. Post successful reassembly, packet can be submitted for > security processing and Rx inject. The packets can be then received in > the application as normal inline protocol processed packets. > > Same API can be leveraged in lookaside protocol offload mode to inject > packet to Rx. This would help in using rte_flow based packet parsing > after security processing. For example, with IPsec, this will help in > flow splitting after IPsec processing is done. > > In both inline protocol capable ethdevs and lookaside protocol capable > cryptodevs, the packet would be received back in eth port & queue based > on rte_flow rules and packet parsing after security processing. The API > would behave like a loopback but with the additional security > processing. > > Signed-off-by: Anoob Joseph <ano...@marvell.com> > Signed-off-by: Vidya Sagar Velumuri <vvelum...@marvell.com> > --- > v3: > * Resolved compilation error with 32 bit build Series Acked-by: Akhil Goyal <gak...@marvell.com>
