Why I did it
In upgrade scenarios, where config_db.json is not carry forwarded to new image, it could be left w/o TACACS credentials.
Added a service to trigger 5 minutes after boot and restore TACACS, if /etc/sonic/old_config/tacacs.json is present.
How I did it
By adding a service, that would fire 5 mins after boot.
This service apply tacacs if available.
How to verify it
Upgrade and watch status of tacacs.timer & tacacs.service
You may create /etc/sonic/old_config/tacacs.json, with updated credentials
(before 5mins after boot) and see that appears in config & persisted too.

Why I did it
To enable syncd-rpc for Barefoot build
How I did it
Set the flag
How to verify it
ENABLE_SYNCD_RPC=y make configure PLATFORM=barefoot
ENABLE_SYNCD_RPC=y make all
#### Why I did it
To avoid the following error
```
Traceback (most recent call last):
File "/usr/local/bin/flush_unused_database", line 10, in <module>
if 'PONG' in output:
TypeError: a bytes-like object is required, not 'str'
```
`communicate` method returns the strings if streams were opened in text mode; otherwise, bytes.
In our case text arg in Popen is not true and that means that `communicate` return the bytes
#### How I did it
Set `text=True` to get strings instead of bytes
#### How to verify it
run `/usr/local/bin/flush_unused_database` inside database container
Why I did it
ndppd by default reads /proc/net/ipv6_route ever 30 seconds. Since T1s advertise so many routes to ToRs, this file is extremely large, and reading it causes ndppd's CPU usage to spike every 30 seconds
How I did it
Increase the delay for reading this file to the maximum possible value (max integer value), which will result in CPU spikes every ~24 days instead of every 30 seconds
How to verify it
Start ndppd with the new config file, confirm that no CPU spikes are seen except at startup

Why I did it
This PR aims to monitor the memory usage of streaming telemetry container and restart streaming telemetry container if memory usage is larger than the pre-defined threshold.
How I did it
I borrowed the system tool Monit to run a script memory_checker which will periodically check the memory usage of streaming telemetry container. If the memory usage of telemetry container is larger than the pre-defined threshold for 10 times during 20 cycles, then an alerting message will be written into syslog and at the same time Monit will run the script restart_service to restart the streaming telemetry container.

2. Always query fan from fan_drawer

Currently, there is a bug in the ntp.conf jinja2 template where it will ignore the src_intf directive in CONFIG_DB if there are multiple IP addresses associated with an interface. This code change fixes that bug and allows the template to select the correct source interface for NTP.
How I did it
I did this by modifying the macro in ntp.conf.j2 which determines if there is an ip address associated with an interface to set a state variable when it detects a valid interface entry in CONFIG_DB instead of outputting "true" directly (which could result in multiple "trues" outputted for interfaces with multiple valid IP addresses).
How to verify it
Add two ipv4 addresses to an interface in SONiC
Add the following configuration to config_db.json
{
"NTP": {
"global": {
"src_intf": "Ethernet1"
}
}
}
Replace Ethernet1 with the interface name of the one you assigned the IP addresses to.
Run sudo config reload -y
Open /etc/ntp.conf and verify that the following line exists
...
interface listen Ethernet1
...
The interface specified should be the one set in the previous steps.

If a process limits using nodes by mempolicy/cpusets, and those nodes become memory exhaustion status, one process may be killed by oom-killer.
No panic occurs in this case, because other node's memory may be free.
This means system total status may be not fatal yet.
