Put a flag for fast-reboot to the db using EXPIRE feature. Using this flag in other part of SONiC to start in Fast-reboot mode. If we reload a config, the state in the db will be removed.
While doing CLI changes for SNMP configuration, few changes are made in backend to handle the modified CLI.
** Changes**
- "community" for "snmp trap" is also made as "configurable". snmpd_conf.j2 is modified to handle the same.
- Changed the snmp.yml file generation from postStartAction to preStartAction in docker_image_ctl.j2 specific to SNMP docker, to ensure that the snmp.yml is generated before sonic-cfggen generates the snmpd.conf.
- Changed to make the code common for management vrf and default vrf. Users can configure snmp trap and snmp listening IP for both management vrf and default vrf.
* [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 is the first step to moving different databases tables into different database instances
in this PR, only handle multiple database instances creation based on user configuration at /etc/sonic/database_config.json
we keep current method to create single database instance if no extra/new DATABASE configuration exist in database_config.json file.
if user try to configure more db instances at database_config.json , we create those new db instances along with the original db instance existing today.
The configuration is as below, later we can add more db related information if needed:
{
...
"DATABASE": {
"redis-db-01" : {
"port" : "6380",
"database": ["APPL_DB", "STATE_DB"]
},
"redis-db-02" : {
"port" : "6381",
"database":["ASIC_DB"]
},
}
...
}
The detail description is at design doc at Azure/SONiC#271
The main idea is : when database.sh started, we check the configuration and generate corresponding scripts.
rc.local service handle old_config copy when loading new images, there is no dependency between rc.local and database service today, for safety and make sure the copy operation are done before database try to read it, we make database service run after rc.local
Then database docker started, we check the configuration and generate corresponding scripts/.conf in database docker as well.
based on those conf, we create databases instances as required.
at last, we ping_pong check database are up and continue

- Make sure that migrated DB contents persisted for next boot
- Make sure that db saved after warm reboot.

* Added debug symbols to many debug dockers.
* For debug images *only*:
1) Archive source files into debug image
2) Archived source is copied into /src
3) Created an empty dir /debug
4) Mount both /src as ro & /debug as rw into every docker
5) Login banner will give some details on /src & /debug
6) Devs can copy core file into /debug and view it from inside a container.
7) Dev may create all gdb logs and other data directly into /debug.
* Dropped redundant REDIS_TOOLS per review comments.
* Added debug symbols to frr package and hence FRR based BGP docker.
* 1) Moved dbg_files.sh to scripts/
2) Src directories to archive are now collected from individual Makefiles.
3) Added few more debug symbols
4) Added few more debug dockers.
Here after no more changes except per review comments.
To debug:
Install required version of debug image in Switch or VM.
Copy core file into /debug of host
Get into Docker
gdb /usr/bin/<daemon> -c /debug/<your core file>
set directory /src/... <-- inside gdb to get the source
For non-in-depth debugging:
Download corresponding debug Docker image (docker-...-dbg.gz) to your VM
Load the image
Run image with entrypoint as 'bash' with dir containing core mapped in.
Run gdb on the core.
* fix fast reboot compatibility
We should handle both cases for backward-compatible with 201803:
- fast-reboot
- SONIC_BOOT_TYPE=fast-reboot
* handle review comments
* add a comment that getBootType code snippet is shared between two files

* Added new platform support DellEMC - Z92264f - 64x100
* Includes changes with Makefiles, sfputil, eeprom and default minigraph
* Led support for Z9264f platform
* Includes changes on default minigraph
* ipmitool implementation in pmon docker. platform_sensors script is inclued in pmon startup
snmp.service needs to read chassis serial number for one of its mibs.
We save this value in state DB so that it is accessible from container.

Existing dockers has paths mounted according to the HWSKU. When HWSKU
changes, these dockers need to be destroyed and recreated with the
correct paths mounted.
Modify minigraph parser output format so it fit DB schema
Modify configuration templates to fit new schema
Systemd services dependencies are modified so database starts before any configuration consumer
- Create /var/run/redis/ folder on the host
- Install Python client for Redis on the host
- Mount /var/run/redis/ as read/write from host for all dockers
- Enable accessing the database everywhere including on the host and from remote

When Type=simple, systemd will consider the service activated immediately
after specified in ExecStart process is started. If there is downstream
service depending on the state prepared in ExecStart, there will be race condition.
For example, issue #390. In this case, database.service calls database.sh, which
calls docker run or docker start -a to start database container. However, systemd
considers database.service successfully started at the time database.sh begins,
not after docker run finishes. As database.service is consider started, bgp.service
can be started. The redis database, which bgp service depends on, might or might not
have been started at this time point.
To fix this issue (and still keeping the functionality to monitor docker status with
systemd), we split the ExecStart process into an ExecStartPre part and an ExecStart
part. docker run is splitted into docker run -d then docker attach , while docker start
-a is splitted into docker start and then docker attach. In this way, we make sure
the downstream services are blocked until container is successfully started.
( All device-specific files now reside under /device directory in a <vendor-name>/<platform-string>/<hardware-SKU> directory structure in repo.
* Device-specific files are now packaged into a Debian package (sonic-device-data) and are now installed to /usr/share/sonic/device/<platform-string>/<hardware-SKU>/ directory on switch.
* Single image
* Fix review comments
* Update syncd service. Add HW mgmt to Mellanox single image.
* Add single image template for Broadcom platform.
SKU should be provided during configure:
make configure PLATFORM=broadcom SKU=Force10-S6000
* Add single image template for Cavium platform.
