Why I did it
To overwrite the default DSCP_TO_TC_MAP for tunnel traffic, the attribute sai_tunnel_support must be set to 1.
Before this change, the attribute is set only on dual-tor platform when remap is enabled.
This PR is to set the attribute on all Arista-7260cx3 devices.

How I did it
Update the config.bcm template for Arista-7260cx3 devices.
How to verify it
The change is verified by manually rendering the j2 on a T1 testbed.
* Update sairedis submodule
This submodule update needs to be manually done due to build changes
done in the sairedis submodule. Specifically, Debian build profiles are
now being used instead of dpkg build targets, and dbgsym packages are
being used instead of dbg packages. Because of this, there needs to be
changes on the sonic-buildimage side for this.
This is a reland of #15720, which was reverted in #15995 due to the RPC
package build failing. That failure has since been fixed, and the
PR pipeline has been updated to build the RPC package so that this is
checked at the PR stage.
This submodule update brings in the following changes:
```

2. The dash-api was installed in the system folder that cannot be imported by the virtual python3 environment. But the testcases of DASH in sonic-mgmt are executed in virtual python3 environment.

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:

How I did it
On chassis supervisor bgp feature is disabled in hostcfgd. The dependency between swss and bgp causes the bgp containers to start even though the feature is disabled.
How to verify it
Tests on chassis supervisor and LC
Why I did it
#15284 fixes a case of shell escape exploit for TACACS+. This applies to RADIUS as well. RADIUS creates an unconfirmed user locally on the switch while attempting authentication. popen() is used to execute useradd,usermod and userdel commands. This exposes a vulnerability where a tactically designed username (which could contain explicit linux commands) can lead to getting executed as root.
An example of such a username could be "asd";echo>remoteRCE2;#". This leads to remoteRCE2 getting created in "/".
How I did it
All calls to popen() used to execute useradd, usermod and userdel are replaced with fork()/execl().
How to verify it
Prior to the fix, following is the behavior:
[s@i vm] ssh "asd";echo>remoteRCE2;#"@1.1.1.1
asd";echo>remoteRCE2;#@1.1.1.1's password:
Permission denied, please try again.
On the SONiC switch,
root@sonic:/# ls
accton_as7816_monitor.log home lib64 remoteRCE2 sys
bin host libx32 root tmp
boot initrd.img media run usr
cache.tgz initrd.img.old mnt sbin var
dev lib opt sonic vmlinuz
etc lib32 proc srv vmlinuz.old
root@sonic:/# ls -l
With the fix:
[s@i vm] ssh "asd";echo>remoteRCE2;#"@1.1.1.1
asd";echo>remoteRCE2;#@1.1.1.1's password:
Permission denied, please try again.
root@sonic:/# ls
accton_as7816_monitor.log etc lib mnt sbin usr
bin home lib32 opt sonic var
boot host lib64 proc srv vmlinuz
cache.tgz initrd.img libx32 root sys vmlinuz.old
dev initrd.img.old media run tmp
Verified that RADIUS authentication works as expected for valid users as well.
What I did:
Fix the Loopback0 IPv6 address of LC's in chassis not reachable from peer devices.
Why I did:
For Ipv6 Loopback0 address we only advertise /64 subnet to the peer devices. However, in case of chassis each LC will have it own /128 address of that /64 subnet . Since this /128 address does not get advertised peer devices can-not ping/reach the LC's loopback0.
How I fix:
Advertise /128 Loopback0 Ipv6 address only between i-BGP peers. This way even though /64 is advertised to e-BGP peer devices when packet reaches any of LC's it can reach the appropriate LC's.
How I verify:
Manual verification
UT added for same.

8111 800G interface, split to 2x400G (each has 4 lanes) fails to change interface speed from 400G to 100G during deploy mg. In minigraph.xml, the interface speed configuration is good, but fails to generate the right value to config_db.json.
In order to support this SKU the speed transitioning should support both 4 lanes and 8 lanes in the port_config.ini.
Why I did it
before this change for a 400G to 100G transition, in all cases except when lanes are 8, we would continue and the line
ports.setdefault(port_name, {})['speed'] = port_speed_png[port_name]
would not be executed, hence the default speed will never be set for a case and config_db will not be updated,
where speed is transitioning from 400G to 100G or 40G, but lanes are not equal to 8.
In order for those cases to pass where lanes are not specifically 8, we need the change

#### Why I did it
When a kernel crash occurs, the system will reboot to the kdump capture kernel if kdump is enabled (`config kdump enable`). In the kdump capture boot, it only stores the crash information, and then reboot the system to a normal boot.
In this boot, no SONiC service is started but it invokes `reboot` which is actually the SONiC reboot that depends on SONiC services. There is a logic to skip all SONiC stuff and invoke platform reboot in SONiC reboot to avoid issues.
However, on Nvidia platforms, the platform reboot still depends on SONiC services, which can cause issues.
So, the Debian reboot is called directly in platform reboot if it is invoked from the kdump capture boot.
#### How I did it
Manual test
### Why I did it
- Hostcfgd is handling a lot of tasks and Feature table is by itself an important and big task which can benefit from separation into a new daemon
- Currently, Hostcfgd handles feature table first before other tables an thus other taska such as Aaa, Ntp are delayed. With the split, they can run in paralell
- After the recent config-reload enhancements, Hostcfgd uses a multi-threading approach to listen to PortInitDone. BY splitting the daemon into two, we can avoid having a separate thread by using SubscriberStateTable and Select,.
#### Note:
Depends on host-services PR : https://github.com/sonic-net/sonic-host-services/pull/71
Once the host-services is merged, updating the submodule along with this PR should fix the CI problem
#### How I did it
Refactor the feature related tasks from hostcfgd into a seperate daemon.
#### How to verify it
UT's and Tested on DUT
