SONiC 202205 release feature update
Yanzhao Zhang
Hi team,
I want to provide a quick update on 202205 release.
- In 202205 release, community planned 66 features in total.
- As of today, 26 (39%) features are completed, 6 (9%) features need be cherry-picks and 34 (52%) features will be deferred.
- 202205 images are created successfully, please check Pipelines (sonic-build.azurewebsites.net)
- Below table has the detail, please let me know if you have any question. @Kanna...@dell.com would you please help to update Sonic Roadmap Planning · sonic-net/SONiC Wiki (github.com) with the latest status?
For the deferred features, if the feature owner wants to contribute them to 202211 release, please let me know as well.
On behalf of SONiC community, I want to say THANK YOU all for your contributions!

hostcfgd Redesign | split hostcfgd into multiple services |
Currently hostcfgd is handling a lot of tables and this leads to performance issues. This has lead to many bugs like https://github.com/Azure/sonic-buildimage/issues/8619. So It is necessary to split hostcfgd into multiple services. The requirement is to come up with a design of how to split hostcfgd and what approach to use, either multi threaded or multi process. Based on design approval this needs to be implemented |

Password Hardening |
a user password is the key credential used in order to verify the user accessing the switch and acts as the first line of defense in regards to securing the switch. The complexity of the password, it's replacement capabilities and change frequency define the security level of the first perimeter of the switch. Therefore - in order to further improve and harden the switch - a secure mechanism is required to enforce PW policies. |

Add SAI version check to SONiC build system |
SONiC is not designed to work in backward compatibility with older vendor SAI implementations. SAI headers that SONiC's synd daemon is compiled against are taken from OCP SAI repository while the actual libsai.so is taken from sonic-buildimage vendor's directory. This leads to a situation that sometimes SAI in sonic-sairedis repository is updated but vendor SAI in sonic-buildimage is not. |

Auto Neg Enhancement |
Autonegotiation is a signaling mechanism and procedure used by Ethernet over twisted pair or optical media by which two connected devices choose common transmission parameters, such as speed, duplex mode, and flow control. In the case of SONiC, this feature supports two different types of AutoNeg 1. QSFP(DD) CR/KR modules: This feature provides autonegotiation support for speed, FEC and TX_FIR, the LinkTraining will always be activated when autonegotiation is enabled, and users could enable standalone-link-training to activate the clause 72/93 when autonegotiation is disabled. 2. Native RJ45 ports of non-Gearbox design: This feature provides autonegotiation support for speed and duplex to the native RJ45 coppers if they're manageable by the SAI without external PHY drivers on the Gearbox. |

Link Training |
Link Training is a process by which the transmitter and receiver on a high-speed serial link communicate with each other in order to tune their equalization settings. In theory, link training enables automatic tuning of the finite impulse response (FIR) filter for each channel in an application-specific integrated circuit (ASIC) to achieve the desired bit error rate (BER). In the SONiC system, the ODM vendors rarely provide pre-calibrated pre-emphasis for QSFP(DD) CR/KR modules, which could result in the link reliability issues. With this feature, both IEEE clause 72 and 93 will be activated to dynamically tune the transmitted signal to improve the link quality over the copper cables. This feature could be activated with or without AutoNeg. |
