This is to backport #16096
Why I did it
SONiC changes:
Support Spectrum4 ASIC FW binary building.
Support new SDK sx-obj-desc lib building since new SAI need it.
Remove SX_SCEW debian package from Mellanox SDK build since we are no longer using it (we use libxml2 instead).
Update SAI, SDK, FW to version 4.6.1020/2012.1020/SAIBuild2211.25.1.0
SDK/FW bug fixes
In SPC-1 platforms: Fastboot mode is not operational for Split port with Force mode in 50G speed
SFP modules are kept in disabled state after set LPM (low power mode) on/off for at least 3 minutes.
When preforming fast boot from an old SDK version (currently installed) to a newer one (target version), and the system was initially loaded with a new SDK version (past version), and the system has not been wiped, under specific conditions, the fast boot would use the past version's data and may fail.
SDK/FW Features
On SN2700 all ports can support y cable by credo
SAI bug Fixes
When creating an ACL rule with SAI_ACL_ENTRY_ATTR_FIELD_SRC_IP/SAI_ACL_ENTRY_ATTR_FIELD_DST_IP enabled, and then disabling the field by setting enable=false, a match on L3_type=IPv4 will remain programmed for the rule Issue resolved after the fix
Allow the max scale of virtual routers to be configure for SPC-1, SPC-2, SPC-3 when fastboot enable
Remove default hash key of SRC_MAC, DST_MAC and ETH_TYPE

Caused by: https://github.com/sonic-net/sonic-buildimage/pull/15487
The above PR introduced change to use Management and Loopback Ipv4 and ipv6 addresses as snmpagent address in snmpd.conf file.
With this change, if Link local IP address is configured as management or Loopback IPv6 address, then snmpd tries to open socket on that ipv6 address and fails with the below error:
```
Error opening specified endpoint "udp6:[fe80::5054:ff:fe6f:16f0]:161"
Server Exiting with code 1
```
From RFC4007, if we need to specify non-global ipv6 address without ambiguity, we need to use zone id along with the ipv6 address: <address>%<zone_id>
Reference: https://datatracker.ietf.org/doc/html/rfc4007
##### Work item tracking
- Microsoft ADO **(number only)**:
#### How I did it
Modify snmpd.conf file to use the %zone_id representation for ipv6 address.
#### How to verify it
In VS testbed, modify config_db to use link local ipv6 address as management address:
"MGMT_INTERFACE": {
"eth0|10.250.0.101/24": {
"forced_mgmt_routes": [
"172.17.0.1/24"
],
"gwaddr": "10.250.0.1"
},
"eth0|fe80::5054:ff:fe6f:16f0/64": {
"gwaddr": "fe80::1"
}
},
Execute config_reload after the above change.
snmpd comes up and check if snmpd is listening on ipv4 and ipv6 addresses:

Why I did it
During the upgrade process via k8s, the feature's systemd service will restart as well, all of the feature systemd service has restart number limit, and the limit number is too small, only three times. if fallback happens when upgrade, the start count will be 2, just once again, the systemd service will be down. So, need to bypass this. This restart function will be called when do local -> kube, kube -> kube, kube ->local, each time call this function, we indeed need to restart successfully, so do reset-failed every time we do restart.
When need to go back to local mode, we do systemd restart immediately without waiting the default restart interval time so that we can reduce the container down time.
Work item tracking
Microsoft ADO (number only):

How I did it
Before every restart for upgrade, do reset feature's restart number. The restart number will be reset to 0 to bypass the restart limit.
When need to go back to local mode, we do systemd restart immediately.
How to verify it
Feature's systemd service can be always restarted successfully during upgrade process via k8s.
This is primarily to fix a bug in scapy hitting an error when trying to
listen on multiple interfaces in a single `sniff` call. This also
upgrades it to the current latest version.

When do clean up container images, current code has two bugs need to be fixed. And some variables' name maybe cause confused, change the variables' name.
Work item tracking
Microsoft ADO (number only): 24502294
How I did it
We do clean up after tag latest successfully. But currently tag latest function only return 0 and 1, 0 means succeed and 1 means failed, when we get 1, we will retry, when we get 0, we will do clean up. Actually the code 0 includes another case we don't need to do clean up. The case is that when we are doing tag latest, the container image we want to tag maybe not running, so we can not tag latest and don't need to cleanup, we need to separate this case from 0, return -1 now.
When local mode(v1) -> kube mode(v2) happens, one problem is how to handle the local image, there are two cases. one case is that there was one kube v1 container dry-run(cause we don't relace the local if kube version = local version), we will remove the kube v1 image and tag the local version with ACR prefix and remove local v1 local tag. Another case is that there was no kube v1 container dry-run, we remove the local v1 image directly, cause the local v1 image should not be the last desire version.
About the docker_id variable, it may cause confused, it's actually docker image id, so rename the variable. About the two dicts and the list, rename them to be more readable.
How to verify it
Check tag latest and image clean up result.
#### Why I did it
After k8s upgrade a container, k8s can only know the container is running, don't know the service's status inside container. So we need a probe inside container, k8s will call the probe to check whether the container is really ready.
##### Work item tracking
- Microsoft ADO **(number only)**: 22453004
#### How I did it
Add a health check probe inside config engine container, the probe will check whether the start service exit normally or not if the start service exists and call the python script to do container self-related specific checks if the script is there. The python script should be implemented by feature owner if it's needed.

Modify snmpd.conf to start snmpd to listen on specific management and loopback ips instead of listening on any ip.
#### Why I did it
SNMP over IPv6 is not working for all scenarios for a single asic platforms.
The expectation is that SNMP query over IPv6 should work over Management or Loopback0 addresses.
**Specific scenario where this issue is seen**
In case of Lab T0 device, when SNMP request is sent from a directly connected T1 neighbor over Loopback IP, SNMP response was not received.
This was because the SRC IP address in SNMP response was not Loopback IP, it was the PortChannel IP connected to the neighboring device.
```
23:18:51.620897 In 22:26:27:e6:e0:07 ethertype IPv6 (0x86dd), length 105: fc00::72.41725 > **fc00:1::32**.161: C="msft" **GetRequest**(28) .1.3.6.1.2.1.1.1.0
23:18:51.621441 Out 28:99:3a:a0:97:30 ethertype IPv6 (0x86dd), length 241: **fc00::71**.161 > fc00::72.41725: C="msft" **GetResponse**(162) .1.3.6.1.2.1.1.1.0="SONiC Software Version: SONiC.xxx - HwSku: xx - Distribution: Debian 10.13 - Kernel: 4.19.0-12-2-amd64"
```
In case of IPv4, the SRC IP in SNMP response was correctly set to Loopback IP.
```
23:25:32.769712 In 22:26:27:e6:e0:07 ethertype IPv4 (0x0800), length 85: 10.0.0.57.56701 > **10.1.0.32**.161: C="msft" **GetRequest**(28) .1.3.6.1.2.1.1.1.0
23:25:32.975967 Out 28:99:3a:a0:97:30 ethertype IPv4 (0x0800), length 221: **10.1.0.32**.161 > 10.0.0.57.56701: C="msft" **GetResponse**(162) .1.3.6.1.2.1.1.1.0="SONiC Software Version: SONiC.xxx - HwSku: xx - Distribution: Debian 10.13 - Kernel: 4.19.0-12-2-amd64"
```
**Sequence of SNMP request and response**
1. SNMP request will be sent with SRC IP fc00::72 DST IP fc00:1::32
2. SNMP request is received at SONiC device is sent to snmpd which is listening on port 161 :::161/
3. snmpd process will parse the request create a response and sent to DST IP fc00::72.
snmpd process does not track the DST IP on which the SNMP request was received, which in this case is Loopback IP.
snmpd process will only keep track what is tht IP to which the response should be sent to.
4. snmpd process will send the response packet.
5. Kernel will do a route look up on destination IP and find the best path.
ip -6 route get fc00::72
fc00::72 from :: dev PortChannel101 proto kernel src fc00::71 metric 256 pref medium
5. Using the "src" ip from about, the response is sent out. This SRC ip is that of the PortChannel and not the device Loopback IP.
The same issue is seen when SNMP query is sent from a remote server over Management IP.
SONiC device eth0 --------- Remote server
SNMP request comes with SRC IP <Remote_server> DST IP <Mgmt IP>
If kernel finds best route to Remote_server_IP is via BGP neighbors, then it will send the response via front-panel interface with SRC IP as Loopback IP instead of Management IP.
Main issue is that in case of IPv6, snmpd ignores the IP address to which SNMP request was sent, in case of IPv6.
In case of IPv4, snmpd keeps track of DST IP of SNMP request, it will keep track if the SNMP request was sent to mgmt IP or Loopback IP.
Later, this IP is used in ipi_spec_dst as SRC IP which helps kernel to find the route based on DST IP using the right SRC IP.
https://github.com/net-snmp/net-snmp/blob/master/snmplib/transports/snmpUDPBaseDomain.c#L300
ipi.ipi_spec_dst.s_addr = srcip->s_addr
Reference: https://man7.org/linux/man-pages/man7/ip.7.html
```
If IP_PKTINFO is passed to sendmsg(2)
and ipi_spec_dst is not zero, then it is used as the local
source address for the routing table lookup and for
setting up IP source route options. When ipi_ifindex is
not zero, the primary local address of the interface
specified by the index overwrites ipi_spec_dst for the
routing table lookup.
```
**This issue is not seen on multi-asic platform, why?**
on multi-asic platform, there exists different network namespaces.
SNMP docker with snmpd process runs on host namespace.
Management interface belongs to host namespace.
Loopback0 is configured on asic namespaces.
Additional inforamtion on how the packet coming over Loopback IP reaches snmpd process running on host namespace: https://github.com/sonic-net/sonic-buildimage/pull/5420
Because of this separation of network namespaces, the route lookup of destination IP is confined to routing table of specific namespace where packet is received.
if packet is received over management interface, SNMP response also is sent out of management interface. Same goes with packet received over Loopback Ip.
##### Work item tracking
- Microsoft ADO **17537063**:
#### How I did it
Have snmpd listen on specific Management and Loopback IPs specifically instead of listening on any IP for single-asic platform.
Before Fix
```
admin@xx:~$ sudo netstat -tulnp | grep 161

udp6 0 0 :::161 :::* 15631/snmpd
```
After fix
```
admin@device:~$ sudo netstat -tulnp | grep 161
udp 0 0 10.1.0.32:161 0.0.0.0:* 215899/snmpd

udp6 0 0 fc00:2::32:161 :::* 215899/snmpd
```
**How this change helps with the issue?**
To see snmpd trace logs, modify snmpd to start using the below parameters, in supervisord.conf file
```
/usr/sbin/snmpd -f -LS0-7i -Lf /var/log/snmpd.log
```
When snmpd listens on any IP, snmpd binds to IPv4 and IPv6 sockets as below:
```
netsnmp_udpbase: binding socket: 7 to UDP: [0.0.0.0]:0->[0.0.0.0]:161
trace: netsnmp_udp6_transport_bind(): transports/snmpUDPIPv6Domain.c, 303:
netsnmp_udpbase: binding socket: 8 to UDP/IPv6: [::]:161
```
When IPv4 response is sent, it goes out of fd 7 and IPv6 response goes out of fd 8.
When IPv6 response is sent, it does not have the right SRC IP and it can lead to the issue described.
When snmpd listens on specific Loopback/Management IPs, snmpd binds to different sockets:
```
trace: netsnmp_udpipv4base_transport_bind(): transports/snmpUDPIPv4BaseDomain.c, 207:
netsnmp_udpbase: binding socket: 7 to UDP: [0.0.0.0]:0->[10.250.0.101]:161
trace: netsnmp_udpipv4base_transport_bind(): transports/snmpUDPIPv4BaseDomain.c, 207:
netsnmp_udpbase: binding socket: 8 to UDP: [0.0.0.0]:0->[10.1.0.32]:161
trace: netsnmp_register_agent_nsap(): snmp_agent.c, 1261:
netsnmp_register_agent_nsap: fd 8
netsnmp_udpbase: binding socket: 10 to UDP/IPv6: [fc00:1::32]:161
trace: netsnmp_register_agent_nsap(): snmp_agent.c, 1261:
netsnmp_register_agent_nsap: fd 10
netsnmp_ipv6: fmtaddr: t = (nil), data = 0x7fffed4c85d0, len = 28
trace: netsnmp_udp6_transport_bind(): transports/snmpUDPIPv6Domain.c, 303:
netsnmp_udpbase: binding socket: 9 to UDP/IPv6: [fc00:2::32]:161
```
When SNMP request comes in via Loopback IPv4, SNMP response is sent out of fd 8
```
trace: netsnmp_udpbase_send(): transports/snmpUDPBaseDomain.c, 511:
netsnmp_udp: send 170 bytes from 0x5581f2fbe30a to UDP: [10.0.0.33]:46089->[10.1.0.32]:161 on fd 8
```
When SNMP request comes in via Loopback IPv6, SNMP response is sent out of fd 10
```
netsnmp_ipv6: fmtaddr: t = (nil), data = 0x5581f2fc2ff0, len = 28
trace: netsnmp_udp6_send(): transports/snmpUDPIPv6Domain.c, 164:
netsnmp_udp6: send 170 bytes from 0x5581f2fbe30a to UDP/IPv6: [fc00::42]:43750 on fd 10
```
#### How to verify it
Verified on single asic and multi-asic devices.
Single asic SNMP query with Loopback
```
ARISTA01T1#bash snmpget -v2c -c xxx 10.1.0.32 1.3.6.1.2.1.1.1.0

```
#### How I did it
#### How to verify it
#### Description for the changelog
- What I did
Added support for secure upgrade.
- How I did it
During sonic_installer install, added secure upgrade image verification.
HLD can be found in the following PR: sonic-net/SONiC#1024
- Why I did it
Feature is used to allow image was not modified since built from vendor. During installation, image can be verified with a signature attached to it.
- How I did it
Feature includes image signing during build (in sonic buildimage repo) and verification during image install (in sonic-utilities).
- How to verify it
In order for image verification - image must be signed - need to provide signing key and certificate (paths in SECURE_UPGRADE_DEV_SIGNING_KEY and SECURE_UPGRADE_DEV_SIGNING_CERT in rules/config) during build , and during image install, need to enable secure boot flag in bios, and signing_certificate should be available in bios.
- Feature dependencies
In order for this feature to work smoothly, need to have secure boot feature implemented as well.
The Secure boot feature will be merged in the near future.
