This PR is to handle the issue 3527.
When device boots up, NTP throws a traceback as explained in the issue 3527.
- Traceback will be seen when MGMT_VRF_CONFIG does not exist in the database. Traceback is coming from the script “/etc/init.d/ntp”.
- Traceback does not affect the NTP functionality with/without management VRF. When MGMT_VRF_CONFIG does not exist or when MGMT_VRF_CONFIG’s mgmtVrfEnabled is configured to “false”, “NTP” will be started in the “default VRF” context, which is working fine even with this traceback.
- This traceback error will be hidden by redirecting the error to /dev/null without affecting functionality.
Add the same mechanism I developed for the SwSS service in #2845 to the syncd service. However, in order to cause the SwSS service to also exit and restart in this situation, I developed a docker-wait-any program which the SwSS service uses to wait for either the swss or syncd containers to exit.
* In the event of a kernel crash, we need to gather as much information
as possible to understand and identify the root cause of the crash.
Currently, the kernel does not provide much information, which make
kernel crash investigation difficult and time consuming.
Fortunately, there is a way in the kernel to provide more information
in the case of a kernel crash. kdump is a feature of the Linux kernel
that creates crash dumps in the event of a kernel crash. This PR
will add kermel kdump support.
An extension to the CLI utilities config and show is provided to
configure and manage kdump:
- enable / disable kdump functionality
- configure kdump (how many kernel crash logs can be saved, memory
allocated for capture kernel)
- view kernel crash logs

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.

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.
- 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.

Issue Overview
shutdown flow
For any shutdown flow, which means all dockers are stopped in order, pmon docker stops after syncd docker has stopped, causing pmon docker fail to release sx_core resources and leaving sx_core in a bad state. The related logs are like the following:
INFO syncd.sh[23597]: modprobe: FATAL: Module sx_core is in use.
INFO syncd.sh[23597]: Unloading sx_core[FAILED]
INFO syncd.sh[23597]: rmmod: ERROR: Module sx_core is in use
config reload & service swss.restart
In the flows like "config reload" and "service swss restart", the failure cause further consequences:
sx_core initialization error with error message like "sx_core: create EMAD sdq 0 failed. err: -16"
syncd fails to execute the create switch api with error message "syncd_main: Runtime error: :- processEvent: failed to execute api: create, key: SAI_OBJECT_TYPE_SWITCH:oid:0x21000000000000, status: SAI_STATUS_FAILURE"
swss fails to call SAI API "SAI_SWITCH_ATTR_INIT_SWITCH", which causes orchagent to restart. This will introduce an extra 1 or 2 minutes for the system to be available, failing related test cases.
reboot, warm-reboot & fast-reboot
In the reboot flows including "reboot", "fast-reboot" and "warm-reboot" this failure doesn't have further negative effects since the system has already rebooted. In addition, "warm-reboot" requires the system to be shutdown as soon as possible to meet the GR time restriction of both BGP and LACP. "fast-reboot" also requires to meet the GR time restriction of BGP which is longer than LACP. In this sense, any unnecessary steps should be avoided. It's better to keep those flows untouched.
summary
To summarize, we have to come up with a way to ensure:
shutdown pmon docker ahead of syncd for "config reload" or "service swss restart" flow;
don't shutdown pmon docker ahead of syncd for "fast-reboot" or "warm-reboot" flow in order to save time.
for "reboot" flow, either order is acceptable.
Solution
To solve the issue, pmon shoud be stopped ahead of syncd stopped for all flows except for the warm-reboot.
- How I did it
To stop pmon ahead of syncd stopped. This is done in /usr/local/bin/syncd.sh::stop() and for all shutdown sequence.
Now pmon stops ahead of syncd so there must be a way in which pmon can start after syncd started. Another point that should be taken consideration is that pmon starting should be deferred so that services which have the logic of graceful restart in fast-reboot and warm-reboot have sufficient CPU cycles to meet their deadline.
This is done by add "syncd.service" as "After" to pmon.service and startin /usr/local/bin/syncd.sh::wait()
To start pmon automatically after syncd started.

* [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

* 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.

* update mellanox components (built with new kernel)
* [mlnx] add make files for SDK WJH libs
* Update arista driver submodule (#8)
Make the debian packaging point to a newer kernel version.
* Updated Makefile infrastructure to build debug images.
As a sample, platform/broadcom/docker-orchagent-brcm.mk is updated to add a docker-orchagent-brcm-dbg.gz target.
Now "BLDENV=stretch make target/docker-orchagent-brcm-dbg.gz" will build the debug image.
NOTE: If you don't specify NOSTRETcH=1, it implicitly calls "make stretch", which builds all stretch targets and that would include debug dockers too.
This debug image can be used in any linux box to inspect core file. If your module's external dependency can be suitably mocked, you my even manually run it inside.
"docker run -it --entrypoint=/bin/bash e47a8fb8ed38"
You may map the core file path to this docker run.
* Dropped the regular binary using DBG_PACKAGES and a small name change to help readability.
* Tweaked the changes to retain the existing behavior w.r.t INSTALL_DEBUG_TOOLS=y.
When this change ('building debug docker image transparently') is extended to all dockers, this flag would become redundant. Yet, there can be some test based use cases that rely on this flag.
Until after all the dockers gets their debug images by default and we switch all use cases of this flag to use the newly built debug images, we need to maintain the existing behavior.
* 1) slave.mk - Dropped unused Docker build args
2) Debug template builder: renamed build_dbg_j2.sh to build_debug_docker_j2.sh
3) Dropped insignifcant statement CMD from debug Docker file, as base docker has Entrypoint.
* Reverted some changes, per review comments.
"User, uid, guid, frr-uid & frr-guid" are required for all docker images, with exception of debug images.
* Get in sync with the new update that filters out dockers to be built (SONIC_STRETCH_DOCKERS_FOR_INSTALLERS) and build debug-dockers only for those to be built and debug target is available.
* Mkae a template for each target that can be shared by all platforms.
Where needed a platform entry can override the template.
This avoids duplication, hence easier to maintain.
* A small change, that can fit better with other targets too.
Just take the platform code and do the rest in template.
* Extended debug to all stretch based docker images
* 1) Combined all orchagent makefiles into one platform independent make under rules/docker-orchagent.mk
2) Extened debug image to all stretch dockers
* Changes per review comments:
1) Dropped LIBSAIREDIS_DBG from database, teamd, router-advertiser, telemetry, and platform-monitor docker*.mk files from _DBG_DEPENDS list
2) W.r.t docker make for syncd, moved DEPENDS from template to specific makefile and let the template has stuff that is applicable to all.
* 1) Corrected a copy/paste mistake
* Fixed a copy/paste bug
* The base syncd dockers follow a template, which defines the base docker as DOCKER_SYNCD_BASE instead of DOCKER_SYNCD_<platform code>. Fix the docker-syncd-<mlnx, bfn>.mk to use the new one.
[Yet to be tested locally]
* Fixed spelling mistake
* Enable build of dbg-sonic-broadcom.bin, which uses dbg-dockers in place of regular dockers, for dockers that build debug version. For dockers that do not build debug version, it uses the regular docker.
This debug bin is installable and usable in a DUT, just like a regular bin.
* Per review comments:
1) Share a single rule for final image for normal & debug flavors (e.g. sonic-broadcom.bin & sonic-broadcom-dbg.bin)
2) Put dbg as suffix in final image name.
3) Compared target/sonic-broadcom.bin.logs with & w/o fix to verify integrity of sonic-broadcom.bin
4) Compared target/sonic-broadcom.bin.logs with sonic-broadcom-dbg.bin.log for verification
This fix takes care of ONIE image only. The next PR will cover the rest.
The next PR, will also make debug image conditional with flag.
* Updated per comments.
Now that debug dockers are available, do not need a way to install debug symbols in regular dockers.
With this commit, when INSTALL_DEBUG_TOOLS=y is set, it builds debug dockers (for dockers that enable debug build) and the final image uses debug dockers. For dockers that do not enable debug build, regular dockers get used in the final image.
Note:
The debug dockers are explicitly named as <docker name>-dbg.gz. But there is no "-dbg" suffix for image.
Hence if you make two runs with and w/o INSTALL_DEBUG_TOOLS=y, you have complete set of regular dockers + debug dockers. But the image gets overwritten.
Hence if both regular & debug images are needed, make two runs, as one with INSTALL_DEBUG_TOOLS=y and one w/o. Make sure to copy/rename the final image, before making the second run.

Some older systems only have 2GB of flash available. Installing a second

The new installation process moves the installer swi to memory in order

It removes all the flash space usage spike and also improves the IO
since the installation is no more reading and writting to the flash at
the same time.

* 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.

- 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)

- How to verify it
build image for wedge100bf_32x
perform sudo config reload -y on new installation
check the correct configuration of usb0 interface

* [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.

This script shall not flush all the entries in the state database
when it starts up, since there are entries maintained and written
by other processes outside this docker.

up after teamsyncd writes the entries into the database, which
causes the IPs failed to be configured because intfmgrd considers

Flashes used for the 7050QX-32 and 7050QX-32S have a fw issue.
The best option to solve the problem is to upgrade to a newer firmware.
However this can only be done while in memory and take 10 seconds.
Adding an upgrade mechanism is possible but would need more
consideration as flashing the firmware and reformating the flash will
exceed the fast-reboot requirements.
A quick mitigation is to align the ext4 partition that we create on
these vfat based system on a 4k boundary.
Here we chose 1M instead but it's the same.
Newer version of sfdisk do this automatically but the one in SONiC
today doesn't have this behavior.
This workaround will only reduce the pace of the flash health
degradation. The only long term fix is to flash the firmware.

With this change SWI_DEFAULT= will be considered the default image and

When executing the boot0 SWI= will be overriden by SWI_DEFAULT= if it
exists and create in with the value of SWI= otherwise.
On overlay filesystem the name of the mountpoint will also match in the
mount command for overlayfs as upperdir=

This ensure that we match mountpoint and not devices in df and mount
outputs.

- Introduce portmgrd which will pick up the MTU configurations from the
configuration database.
- The updated intfmgrd will pick up IP address changes from the configuration
database.

* Fix potential blackholing/looping traffic and refresh ipv6 neighbor to avoid CPU hit
In case ipv6 global addresses were configured on L3 interfaces and used for peering,
and routing protocol was using link-local addresses on the same interfaces as prefered nexthops,
the link-local addresses could be aged out after a while due to no activities towards the link-local
addresses themselves. And when we receive new routes with the link-local nexthops, SONiC won't insert
them to the HW, and thus cause looping or blackholing traffic.
Global ipv6 addresses on L3 interfaces between switches are refreshed by BGP keeplive and other messages.
On server facing side, traffic may hit fowarding plane only, and no refresh for the ipv6 neighbor entries regularly.
This could age-out the linux kernel ipv6 neighbor entries, and HW neighbor table entries could be removed,
and thus traffic going to those neighbors would hit CPU, and cause traffic drop and temperary CPU high load.
Also, if link-local addresses were not learned, we may not get them at all later.
It is intended to fix all above issues.
Changes:
Add ndisc6 package in swss docker and use it for ipv6 ndp ping to update the neighbors' state on Vlan interfaces
Change the default ipv6 neighbor reachable timer to 30mins
Add periodical ipv6 multicast ping to ff02::11 to get/refresh link-local neighbor info.
* Fix review comments:
Add PORTCHANNEL_INTERFACE interface for ipv6 multicast ping
format issue
* Combine regular L3 interface and portchannel interface for looping
* Add ndisc6 package to vs docker
