b8a7a6355b Update the base Debian system installation script to get Bullseye
Python 2 is no longer available, so remove those packages, and remove
the pip2 commands. For picocom and systemd, just install from the
regular repo, since there's no backports yet.

[Nokia ixs7215] Add support for changing the console baud rate (#8595)
This commit adds support for changing the default console baud rate configured
within the U-Boot bootloader. That default baud rate is exposed via the value
of the U-Boot 'baudrate' environment variable. This commit removes logic that
hardcoded the console baud rate to 115200 and instead ensures that the U-Boot
'baudrate' variable is always used when constructing the Linux kernel boot
arguments used when booting Sonic.

A change is also made to rc.local to ensure that the specified baud rate is set
correctly in the serial getty service.

c8b5daed27 Upgrade to ifupdown2 3.0.0 with a patch to fix using broadcast addresses
In version 3.0.0, If a broadcast address is specified in
/etc/network/interfaces, then when ifup is run, it will fail with an
error saying `'str' object has no attribute 'packed'`. This appears to
be because it expects all attributes for an interface to be "packable"
into a compact binary representation. However, it doesn't actually
convert the broadcast address into an IPNetwork object (other addresses
are handled).

Therefore, convert the broadcast address it reads in from a str to an
IPNetwork object.

Also explicitly specify the scope of the loopback address in
/etc/network/interfaces as host scope. Otherwise, it will get added as
global scope by default. As part of this, use JSON to parse ip's output
instead of text, for robustness.

[dhcp_relay] Disable dhcp_relay for ToRRouter switches type by the feature manager (#7789)
- Why I did it
Currently dhcp packets are disabled by the COPP manager for non ToRRouter type switches.
Even if the feature is enabled, DHCP packets wont hook to the CPU since the COPP manager will not trap this packets.
This change is to disable dhcp_relay by default for non ToRRouter switches from init_cfg.json.
With this approach, if the user want to enable the feature for non ToRRouter switches, manual enablement is required by the 'feature' configuration.
This is to keep the current approach for MSFT production issue with dhcp relay for non ToRRouter switched and allow the user to decide if to use it or not.

- How I did it
Configure dhcp_relay 'disabled' by default on init_cfg.json for non ToRRouter switches.
Remove the exclusion of dhcp packets on copp_cfg.json

- How to verify it
Enable dhcp_relay feature on a non ToRRouter switch.
Unit-tests modified so the default values on mocked CONFIG DB in 'test_vectors.py' for dhcp_relay will be 'disabled'.
This is by the change for 'init_cfg.json.j2'.
For ToRRouter the state will change from 'disabled' to 'enabled'.
Another test case added for a 'ToR' switch type, this is to test the state is 'enabled' if the user configured it to be so.

Add service to restore TACACS from old config (#7560)
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.

[Monit] Restart telemetry container if memory usage is beyond the threshold (#7645)
Signed-off-by: Yong Zhao yozhao@microsoft.com

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.

How to verify it
I verified this implementation on device str-7260cx3-acs-1.

#### Why I did it
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.

[ntp] Fix ntp.conf template to allow setting of source port in CONFIG_DB (#7586)
Why I did it
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.

99-default.link - was always in SONiC, but previous systemd (<247) had an issue and it did not work due to issue systemd/systemd#3374. Now systemd 247 works.

However, such policy overrides teamd provided mac address which causes teamd netdev to use a random mac
address. Therefore, needs to be disabled.

  value is "false".
* Add a set of test cases for the new voq_chassis templates in
  sonic-bgpcfgd tests.

Note that the templates expect the new
"bgp bestpath peer-type multipath-relax" bgpd configuration to be

[multi-asic][vs]: Update topology script to retrieve hwsku from minigraph (#6219)
Update topology script to retrieve hwsku from minigraph
if hwsku information is not available in config_db.
Fix clean up of interfaces in msft_multi_asic_vs hwsku
topology script.
- Why I did it
When bringing up multi-asic VS switch, topology service is started during boot up.
Topology service starts a shell script which runs the topology script present in /usr/share/sonic/device// directory. To invoke hwsku specific script, the topology script tries to retrieve hwsku information from config_db.
During initial boot up config_db might not be populated. In order to start topology service before config_db is updated,
update topology script to get hwsku information from minigraph.xml if it is available.
This will be helpful to bring up multi-asic VS testbed by loading minigraph and starting topology service.
- How I did it
Update topology.sh script to retrieve hwsku information from minigraph.xml.
Fix clean up function on msft_multi_asic_vs toplogy script.
- How to verify it
single-asic VS - no change; topology service is only enabled for multi-asic VS.
multi-asic VS - Bring up multi-asic VS image, copy minigraph to vs image, start topology service. Topology service should be successful.
to test clean up function fix, start topology service - make sure interfaces are created and moved to the right namespaces.
stop topology service - make sure namespace do not have any interface and all front end interfaces are present in default namespace.

[kdump] Fix OOM events in crashkernel (#6447)
A few issues where discovered with crashkernel on Arista platforms.

1) platforms using `docker_inram=on` would end up OOM in kdump environment.
This happens because the same initramfs is used by SONiC and the crashkernel.
With `docker_inram=on` the `dockerfs.tar.gz` is extracted in a `tmpfs` created for the occasion.
Since `dockerfs.tar.gz` weights more than 1.5G, it doesn't fit into the kdump environment and ends up OOM.
This OOM event can in turn trigger a panic.

2) Arista platforms with `secureboot` enabled would fail to load the crashkernel because the kernel parameter would be discarded on boot.
This happens because the `boot0` in secureboot mode is strict about kernel parameter injection.

3) The secureboot path allowlist would remove kernel crash reports.

4) The kdump service would fail on Arista products since `/boot/` is empty in `secureboot`

**- How I did it**

1) To prevent an OOM event in the crashkernel the fix is to avoid the codepaths in `union-mount` that create tmpfs and populate them. Some more codepath specific to Arista devices are also skipped to make the kdump process faster.
This relies on detecting that the initramfs is starting in a kdump environment and skipping some initialization.
The `/usr/sbin/kdump-config` tool appends a few kernel cmdline arguments when loading the crashkernel.
The most unique one is `systemd.unit=kdump-tools.service` which is used in a few initramfs hooks to set `in_kdump`.

2) To allow `kdump` to work in `secureboot` environment the cmdline generation in boot0 was slightly modified.
The codepath to load kernel parameters changed by SONiC is now running for booting in secure mode.
It was altered to prevent an append only behavior which would grow the `kernel-cmdline` at every reboot.
This ever growing behavior would lead `kexec` to fail to load the kernel due to a too long cmdline.

3) To get the kernel crash under /var/crash this path has to be added to `allowlist_paths`

4) The `/host/image-XXX/boot` folder is now populated in `secureboot` mode but not used.

**- How to verify it**

Regular boot:
 - enable kdump
 - enable docker_inram=on via kernel-params
 - reboot
 - generate a crash `echo c > /proc/sysrq-trigger`
 - before: witness OOM events on the console
 - after: crash kernel works and crash available under /var/crash

Secure boot:
 - enable kdump
 - reboot
 - generate a crash `echo c > /proc/sysrq-trigger`
 - before: witness no kdump
 - after: crash kernel works and crash available under /var/crash

- Support for Multi-asic platforms. Ebtable filters are installed in namespace for multi-asic and not host. On Single asic installed on  host.

- For Multi-asic platforms we don't want to install on host otherwise Namespace-to-Namespace communication does not happens since ARP Request are not forwarded.

- Updated to use text file to restore ebtables rules then the binary format. Rules are restore as part of Database docker init instead of rc.local

- Removed the ebtable service files for buster as not needed as filters are restored/installed as part of database docker init.
   All the binaries are pre-installed with ebtables* binary are same as ebatbles-legacy-*

[Monit] Monitoring the running status of containers. (#6251)
**- Why I did it**
This PR aims to monitor the running status of each container. Currently the auto-restart feature was enabled. If a critical process exited unexpected, the container will be restarted. If the container was restarted 3 times during 20 minutes, then it will not run anymore unless we cleared the flag using the command `sudo systemctl reset-failed <container_name>` manually. 

**- How I did it**
We will employ Monit to monitor a script. This script will generate the expected running container list and compare it with the current running containers. If there are containers which were expected to run but were not running, then an alerting message will be written into syslog.

**- How to verify it**
I tested this feature on a lab device `str-a7050-acs-3` which has single ASIC and `str2-n3164-acs-3` which has a Multi-ASIC. First I manually stopped a container by running the command `sudo systemctl stop <container_name>`, then I checked whether there was an alerting message in the syslog.

Take a copy of existing TACACS credentials and restore it during upgrade (#6285)
In scenario where upgrade gets config from minigraph, it could miss tacacs credentials as they are not in minigraph. Hence restore explicitly upon load-minigraph, if present.

- Why I did it
Upon boot, when config migration is required, the switch could load config from minigraph. The config-load from minigraph would wipe off TACACS key and disable login via TACACS, which would disable all remote user access. This change, would re-configure the TACACS if there is a saved copy available.

- How I did it
When config is loaded from minigraph, look for a TACACS credentials back up (tacacs.json) under /etc/sonic/old_config. If present, load the credentials into running config, before config-save is called.

- How to verify it
Remove /etc/sonic/config_db.json and do an image update. Upon reboot, w/o this change, you would not be able ssh in as remote user. You may login as admin and check out, "show tacacs" & "show aaa" to verify that tacacs-key is missing and login is not enabled for tacacs.
With this change applied, remove /etc/sonic/config_db.json, but save tacacs & aaa credentials as tacacs.json in /etc/sonic/. Upon reboot, you should see remote user access possible.
