We noticed in tests/production that there is a low probability failure
where /etc/hosts could have some garbage characters before the entry for
local host name. The consequence is that all sudo command would be very
slow. In extreme cases it would prevent some services from starting
properly.
I suspect that the /etc/hosts file might be opened by some process causing
the issue. Editing contents with new file level and replace the whole file
should be safer.

- after reloading minigraph, write latest version string in the DB.
- if old config_db.json file exists, use it and migrate to latest version.
- only reload minigraph when config_db.json doesn't exist and minigraph
exists.

* [SNMP] management VRF SNMP support
This commit adds SNMP support for Management VRF using l3mdev.
The patch included provides VRF support, there is no single
"listendevice" configuration, rather multiple agentaddress
config options can each have their own "interface" to bind to
using "ip%interface". The snmpd.conf file is accordingly
generated using the snmp.yml file and redis database info.
Adding below the comments of SNMP patch 1376
--------------------------------------------
Since the Linux kernel added support for Virtual Routing
and Forwarding (VRF) in version 4.3
(Note: these won't compile on non-linux platforms)
https://www.kernel.org/doc/Documentation/networking/vrf.txt
Linux users could not use snmpd in its current form to
bind specific listening IP addresses to specific VRF
devices. A simplified description of a VRF inteface
is an interface that is a master (a container of sorts)
that collects a set of physicalinterfaces to form a
routing table.
This set of two patches (one for V5-7-patches and one
for V5-8-patches branches) is almost identical to patch
single "listendevice" configuration. Rather, multiple
agentAddress config options can each have their own
"interface" to bind to using the <ip>%<interface>
syntax.</interface></ip>

This commit adds NTP support for management VRF using L3mdev. Config vrf add
mgmt will enable management VRF, enslave the eth0 device to the master device
mgmt, stop ntp service in default, restart interfaces-configs and restart ntp
service in mgmt-vrf context. Requirement and design are covered in mgmt vrf
design document.

- monit config broke by one monit upgrade
- abandon sed approach since it is suspestible to monit config changes
- use unixsocket instead of httpd due to a bug in 5.20.0
Present: Servers are listed in the same order as in redis-db
Fix: Save the sort o/p, hence use sorted list to write into pam.d's conf.
As well convert priority to integer for use by sort.

This commit adds support for New feature management VRF using L3mdev. Added
commands to enable/disable management VRF. Config vrf add mgmt will enable
management VRF, enslave the eth0 device to the master device mgmt and restart
interfaces-configs in mgmt-vrf context.
management interface (eth0) can be configured using config interface eth0 ip
add command and removed using config interface eth0 ip remove command.
Requirement and design are covered in mgmt vrf design document. Currently show
command displays linux command output; will update show command display in next
PR after concluding what would be the output for the show commands. Added
metric for default routes in dhcp and static, any changes for metric will be
addressed subsequently after discussing.

* [warm reboot] save configuration after warm reboot
After warm reboot, save a copy of in memory database to config_db.json,
upgrade procedure might have removed config_db.json to force new image
to reload minigraph. However, reload minigraph is skipped during warm
reboot. Missing config_db.json would cause device to fault in next
non-upgrading cold/fast reboot.

* Update finalize-warmboot.sh
In case of going from previous iteration of SONiC, and the last reboot
was hardware, REBOOT_CAUSE_FILE may not be present and the service may
throw an error.
* [logrotate] Decrease frequency to every 10 minutes; kill any lingering logrotate processes
* [logrotate] Delete all *.1.gz files as firstaction; Remove note about init-system-helpers < 1.47 workaround
However, continue to send SIGHUP directly to rsyslogd process
because 'service rsyslog rotate' still doesn't work properly with
init-system-helpers version 1.48
* Switch the nss look up order as "compat" followed by "tacplus".
This helps use the legacy passwd file for user info and go to tacacs only if not found.
This means, we never contact tacacs for local users like "admin".
This isolates local users from any issues with tacacs servers.
W/o this fix, the sudo commands by local users could take <count of servers> * <tacacs timeout> seconds, if the tacacs servers are unreachable.
* Skip tacacs server access for local non-tacacs users.
Revert the order of 'compat tacplus' to original 'tacplus compat' as tacplus
access is required for all tacacs users, who also get created locally.
- Add ebtables package, and install some filter rules:
1. ebtables -A FORWARD -d BGA -j DROP
2. ebtables -A FORWARD -p ARP -j DROP
Basically, we let the ARP packets in the VLAN being forwarded by the ASIC,
kernel gets a copy of these ARP packets and the forwarding from Kenerl gets
dropped. So there is always only one copy of ARP/response in the VLAN.

* Add '$(SUPERVISOR_PROC_EXIT_LISTENER_SCRIPT)' to new shared docker-orchagent makefile
* Make supervisor-proc-exit-listener script read from 'critical_processes' file inside container
* Update critical_processes file for swss container
This service (weekly) will let SSD firmware to do the garbage collection
after file-system deleted files. It could avoid slowness or
even READ-ONLY error due to SSD not being able to free the pages
even though the file system thinks there was a lot of space left.

- Why it is required
since SONiC master switches ifupdown package to the new implementation (ifupdown2), it is required to change the configuration of a platform-specific interface for wedge100bf_32x and wedge100bf_65x platforms (bc of ifupdown2 doesn't support auto mode for inet6 protocol).
Also, need to make some refactoring and remove if platform == smth then.. from the system level scripts.
- What I did
removed customization of /usr/bin/interfaces-config.sh
explicitly created directory /etc/network/interfaces.d
added "source" to the /etc/network/interfaces generation template (to include platform-specific interfaces processing)
added platform-specific interfaces config itself (for wedge100bf_32x and wedge100bf_65x)
fixed testcase in sonic-config-engine
- How to verify it
build image for wedge100bf_32x
perform sudo config reload -y on new installation
check the correct configuration of usb0 interface
- Description for the changelog
Allow configuration of platform-specific interfaces

* [reboot cause] Move reboot-cause files to /host directory so they persist across SONiC upgrades
* [sonic-utilities] Update submodule to include related changes
- What I did
This fix removes the possibility of 'localhost' entry getting removed from /etc/hosts file by hostname-config service.
Without this change, whenever we change the hostname from 'localhost' to any other name on the config_db.json and reload the config, /etc/hosts file will only have the new hostname on it. But there are multiple sonic utilities (eg: swssconfig) which relies on the hard coded 'localhost' name and they tend to stop working.
- How I did it
Added a new check on hostname-config.sh script to avid blindly deleting the line containing the old hostname from /etc/hosts file. Now it will delete the old hostname only if its not localhost or when the hostname is not changing.
- How to verify it
Bring up SONiC on a device with hostname as localhost
Edit /etc/sonic/config_db.json to update the 'hostname' filed under DEVICE_METADATA from "hostname" : "localhost" --> "hostname" : "sonic"
run config reload -y to reflect the hostname change done on config_db.json file.
cat /etc/hosts and check whether both 127.0.0.1 localhost and 127.0.0.1 sonic entry are present on the file.
ping localhost should work fine.
- Description for the changelog
Make hostname-config service more robust in handling SONiC hostname change from localhost to anything else.
* [update graph] adapt to warm reboot scenario

Auto negotiating console speed could cause sonic to lock on a wrong
speed under rare conditions. The only way to come out of the wrong
speed is to issue line break or restart console service with forced
speed, or reboot sonic.
Lock down the console speed to avoid these situations.
