chassis-packet: missing arp entries for static routes causing high orchagent cpu usage
It is observed that some sonic-mgmt test case calls sonic-clear arp, which clears the static arp entries as well. Orchagent or arp_update process does not try to resolve the missing arp entries after clear.
How I did it
arp_update should resolve the missing arp/ndp static route
entries. Added code to check for missing entries and try ping if any
found to resolve it.
How to verify it
After boot or config reload, check ipv4 and ipv4 neigh entries to make sure all static route entries are present
manual validation:
Use sonic-clear arp and sonic-clear ndp to clear all neighbor entries
run arp_update
Check for neigh entries. All entries should be present.
Testing on T0 setup route/for test_static_route.py
The test set the STATIC_ROUTE entry in conifg db without ifname:
sonic-db-cli CONFIG_DB hmset 'STATIC_ROUTE|2.2.2.0/24' nexthop 192.168.0.18,192.168.0.25,192.168.0.23
"STATIC_ROUTE": {
"2.2.2.0/24": {
"nexthop": "192.168.0.18,192.168.0.25,192.168.0.23"
}
},
Validate that the arp_update gets the proper ARP_UPDATE_VARDS using arp_update_vars.j2 template from config db and does not crash:
{ "switch_type": "", "interface": "", "pc_interface" : "PortChannel101 PortChannel102 PortChannel103 PortChannel104 ", "vlan_sub_interface": "", "vlan" : "Vlan1000", "static_route_nexthops": "192.168.0.18 192.168.0.25 192.168.0.23 ", "static_route_ifnames": "" }
validate route/test_static_route.py testcase pass.

How I did it
- Why I did it
To solve an issue with upgrade with fast-reboot including FW upgrade which has been introduced since moving to fast-reboot over warm-reboot infrastructure.
As well, this introduces fast-reboot finalizing logic to determine fast-reboot is done.
- How I did it
Added logic to finalize-warmboot script to handle fast-reboot as well, this makes sense as using fast-reboot over warm-reboot this script will be invoked. The script will clear fast-reboot entry from state-db instead of previous implementation that relied on timer. The timer could expire in some scenarios between fast-reboot finished causing fallback to cold-reboot and possible crashes.
As well this PR updates all services/scripts reading fast-reboot state-db entry to look for the updated value representing fast-reboot is active.
- How to verify it
Run fast-reboot and check that fast-reboot entry exists in state-db right after startup and being cleared as warm-reboot is finalized and not due to a timer.

Why I did it
Orchagent sometimes take additional time to execute Tunnel tasks. This cause write_standby script to error out and mux state machines are not initialized. It results in show mux status missing some ports in output.

Mar 13 20:37:58.983412 m64-tor-0-yy41 NOTICE swss#orchagent: :- doTask: Tunnel(s) added to ASIC_DB.
How I did it
Increase timeout from 60s to 90s
How to verify it
Verified that mux state machine is initialized and show mux status has all needed ports in it.
Why I did it
At service start up time, there are chances that the networking service is being restarted by interface-config service. When that happens, write_standby could fail to make DB connections due to loopback interface is being reconfigured.
How I did it
Force the db connector to use unix socket to avoid loopback reconfig timing window.
How to verify it
Run config reload test 20+ times and no issue encountered.

Why I did it
All these 3 services started after swss service, which used to start after interface-config service. But #13084 remove the time constraints for swss.
After that, these 3 services has the chance of start earlier when the inteface-config service is restarting the networking service, which could cause db connect request to fail.
How I did it

How I did it
Why I did it
SONiC currently does not identify 'EdgeZoneAggregator' neighbor. As a result, the buffer profile attached to those interfaces uses the default cable length which could cause ingress packet drops due to insufficient headroom. Hence, there is a need to update the buffer templates to identify such neighbors and assign the same cable length as used by the T1.
How I did it
Modified the buffer template to identify EdgeZoneAggregator as a neighbor device type and assign it the same cable length as a T1/leaf router.
How to verify it
Unit tests pass, and manually checked on a 7260 to see the changes take effect.

This PR addresses the issue mentioned above by loading the acl config as a service on a storage backend device
How I did it
The new acl service is a oneshot service which will start after swss and does some retries to ensure that the SWITCH_CAPABILITY info is present before attempting to load the acl rules. The service is also bound to sonic targets which ensures that it gets restarted during minigraph reload and config reload
How to verify it
Build an image with the following changes and did the following tests
Verified that acl is loaded successfully on a storage backend device after a switch boot up
Verified that acl is loaded successfully on a storage backend ToR after minigraph load and config reload
Verified that acl is not loaded if the device is not a storage backend ToR or the device does not have a DATAACL table

Add Secure Boot support to SONiC OS.
Secure Boot (SB) is a verification mechanism for ensuring that code launched by a computer's UEFI firmware is trusted. It is designed to protect a system against malicious code being loaded and executed early in the boot process before the operating system has been loaded.
- How I did it
Added a signing process to sign the following components:
shim, grub, Linux kernel, and kernel modules when doing the build, and when feature is enabled in build time according to the HLD explanations (the feature is disabled by default).
- How to verify it
There are self-verifications of each boot component when building the image, in addition, there is an existing end-to-end test in sonic-mgmt repo that checks that the boot succeeds when loading a secure system (details below).
How to build a sonic image with secure boot feature: (more description in HLD)
Required to use the following build flags from rules/config:
SECURE_UPGRADE_MODE="dev"
SECURE_UPGRADE_DEV_SIGNING_KEY="/path/to/private/key.pem"
SECURE_UPGRADE_DEV_SIGNING_CERT="/path/to/cert/key.pem"
After setting those flags should build the sonic-buildimage.
Before installing the image, should prepared the setup (switch device) with the follow:
check that the device support UEFI
stored pub keys in UEFI DB
enabled Secure Boot flag in UEFI
How to run a test that verify the Secure Boot flow:
The existing test "test_upgrade_path" under "sonic-mgmt/tests/upgrade_path/test_upgrade_path", is enough to validate proper boot
You need to specify the following arguments:
Base_image_list your_secure_image
Taget_image_list your_second_secure_image
Upgrade_type cold
And run the test, basically the test will install the base image given in the parameter and then upgrade to target image by doing cold reboot and validates all the services are up and working correctly
Fixes#13568
Upgrade from old image always requires squashfs mount to get the next image FW binary. This can be avoided if we put FW binary under platform directory which is easily accessible after installation:

- Why I did it
202211 and above uses different squashfs compression type that 201911 kernel can not handle. Therefore, we avoid mounting squashfs altogether with this change.
- How I did it
Place FW binary under /host/image-/platform/mlnx/, soft links in /etc/mlnx are created to avoid breaking existing scripts/automation.
/etc/mlnx/fw-SPCX.mfa is a soft link always pointing to the FW that should be used in current image
mlnx-fw-upgrade.sh is updated to prefer /host/image-/platform/mlnx location and fallback to /etc/mlnx in squashfs in case new location does not exist. This is necessary to do image downgrade.

While /etc/resolv.conf has the correct content and ping (and any other utility that uses libc's DNS resolution implementation) works correctly
docker is unable to resolve the hostname and falls back to default [::1]:53. This started to happen after PR https://github.com/sonic-net/sonic-buildimage/pull/13516 has been merged.
As you can see from the log, dockerd is able to pick up the correct /etc/resolv.conf only after 5 sec since first try. This seems to be somehow related to the logic in Go's DNS resolver
https://github.com/golang/go/blob/master/src/net/dnsclient_unix.go#L385.
There have been issues like that reported in docker like:
- https://github.com/docker/cli/issues/2299
- https://github.com/docker/cli/issues/2618
- https://github.com/moby/moby/issues/22398
Since this starts to happen after inclusion of resolvconf package by
above mentioned PR and the fact I can't see any problem with that (ping,
nslookup, etc. works) the choice is made to force dockerd to use cgo
(libc) resolver.

To avoid PFC deadlock, we need to map the bounce-back lossless traffic to different PGs and queues. Therefore, 2 additional lossless PGs and queues are allocated on uplink ports on ToR switches.
On uplink ports, map DSCP 2/6 to TC 2/6 respectively
On downlink ports, both DSCP 2/6 are still mapped to TC 1
Buffer adjusted according to the ports information:
Mellanox-SN4600c-C64:
56 downlinks 50G + 8 uplinks 100G
Mellanox-SN4600c-D48C40, Mellanox-SN2700, Mellanox-SN2700-D48C8:
24 downlinks 50G + 8 uplinks 100G

- Why I did it
fixes#12907
When the management interface IP address configuration changes from dynamic to static the DNS configuration (retrieved from the DHCP server) in /etc/resolv.conf remains uncleared. This leads to a DNS configuration pointing to the wrong nameserver. To make the behavior clear DNS configuration received from DHCP should be cleared.
- How I did it
Use resolvconf package for managing DNS configuration. It is capable of tracking the source of DNS configuration and puts the configuration retrieved from the DHCP servers into a separate file. This allows the implementation of DNS configuration cleanup retrieved from DHCP during networking reconfiguration.
- How to verify it
Ensure that the management interface has no static configuration.
Check that /etc/resolv.conf has DNS configuration.
Configure a static IP address on the management interface.
Verify that /etc/resolv.conf has no DNS configuration.
Remove the static IP address from the management interface.
Verify that /etc/resolv.conf has DNS configuration retrieved form DHCP server.
Fixes#12408
Why I did it
We are running into #12408 very frequently.
This results in no syslogs from any containers as rsyslog server could not start.
some of the sonic-mgmt scripts look for log statements and error out if log is not present.
Interfaces-config service configures the loopback interface along with other interfaces. rsyslog-config reads ip address of loopback interface and generates /etc/rsyslog.conf. When this race condition happens, lo interface ip is not yet programmed and rsyslog-config ends up writing UDP server as null in /etc/rsyslog.conf.
How I did it
rsyslog-config service is started after interfaces-config service.
How to verify it
Did multiple reboots and verified that $UDPServerAddress is valid.
Adding /usr/local/bin/storyteller to READ_ONLY_CMDS. So no write access or prompt for password is needed to run storyteller.
Tested on 202205 clusters, user who didn't request write access was able to grep log using storyteller.

Changing the default config knob value to be True for killing radv, due to the reasons below:
Killing RADV is to prevent sending the "cease to be advertising interface" protocol packet.
RFC 4861 says this ceasing packet as "should" instead of "must", considering that it's fatal to not do this.
In active-active scenario, host side might have difficulty distinguish if the "cease to be advertising interface" is for the last interface leaving.
6.2.5. Ceasing To Be an Advertising Interface
shutting down the system.
In such cases, the router SHOULD transmit one or more (but not more
than MAX_FINAL_RTR_ADVERTISEMENTS) final multicast Router
Advertisements on the interface with a Router Lifetime field of zero.
In the case of a router becoming a host, the system SHOULD also
depart from the all-routers IP multicast group on all interfaces on
which the router supports IP multicast (whether or not they had been
advertising interfaces). In addition, the host MUST ensure that
subsequent Neighbor Advertisement messages sent from the interface
have the Router flag set to zero.

How I did it
radv sends a good-bye packet when the service is stopped, which causes a IPv6 route update on SoC side. And this update leads to an interface bouncing and causes traffic disruption even though the ToR device might already be isolated.
This PR is to mitigate the traffic disruption issue during planned maintenance, by killing radv instead of stopping. So the cease packet won't be sent.

Verified on dev clusters:
Traffic disruption was no longer reproducible.

Ubuntu 22.04 uses cgroup2 by default, but docker.sh doesn't mount it.
As a result we get an error when trying to run docker info in chroot env:
ERROR: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
How I did it
mount cgroup2 in chroot if all enabled kernel cgroup controllers are currently not in use by cgroup1
So we need to mount cgroup in chroot environment on /sys/fs/cgroup.
Because inside chroot we don't know which cgroup version is used by the host we have two possible solutions:
cgroup tree for chroot is mounted by the host (it was my 1st version of this fix)
cgroup tree is mounted inside chroot based on info from /proc/cgroups (it's current version of this fix)
My 2nd version based on this code from systemd: 5c6c587ce2/src/shared/cgroup-setup.c (L35-L74)
We parse info from /proc/cgroups
Skip header line started from #
Skip controller if it's disabled (4th column = 0)
Count number of controllers with non-zero of hierarchy_id (2nd column)
If this number is not zero then we assume some of controllers are used by host system and the host system uses hybrid or legacy cgroup tree. In this case we can't use unified cgroup tree inside chroot and mount old cgroup tree (v1).
If this number is zero then we assume host system uses unified cgroup tree and we need to mount cgroup2 inside chroot.

During docker build, host files can be passed to the docker build through
docker context files. But there is no straightforward way to transfer
the files from docker build to host.
This feature provides a tricky way to pass the cache contents from docker
build to host. It tar's the cached content and encodes them as base64 format
and passes it through a log file with a special tag as 'VCSTART and VCENT'.
Slave.mk in the host, it extracts the cache contents from the log and stores them
in the cache folder. Cache contents are encoded as base64 format for
easy passing.

Why I did it
There is an issue on the Arista PikeZ platform (using T3.X2: BCM56274) while running SONiC. If the 'syncd' container in SONiC is restarted, the expected behaviour is that syncd will automatically restart/recover; however it does not and always fails at create_switch due to BCM SDK kmod DMA operation cancellation getting stuck.

Why I did it
The current lazy installer relies on a filename sort for both unpack and configuration steps. When systemd services are configured [started] by multiple packages the order is by filename not by the declared package dependencies. This can cause the start order of services to differ between first-boot and subsequent boots. Declared systemd service dependencies further exacerbate the issue (e.g. blocking the first-boot script).
The current installer leaves packages un-configured if the package dependency order does not match the filename order.
This also fixes a trivial bug in [Build]: Support to use symbol links for lazy installation targets to reduce the image size #10923 where externally downloaded dependencies are duplicated across lazy package device directories.
How I did it

BGP service has always been starting after interface-config. However, recently we discovered an issue where some BGP sessions are unable to establish due to BGP daemon not able to read the interface IP.
This issue was clearly observed after upgrading to FRR 8.2.2. See more details in #12380.
How I did it
Delaying starting BGP seems to be a workaround for this issue.
However, caution is that this delay might impact warm reboot timing and other timing sequences.
This workaround is reducing the probability of hitting the issue by close to 100X. However, this workaround is not bulletproof as test shows. It is still preferrable to have a proper FRR fix and revert this change in the future.

#### A picture of a cute animal (not mandatory but encouraged)
There's an odd crash that intermittently happens after the teamd container
exits, and a signal is raised to the main thread to exit. This thread (watching
teamd) continues execution because it's in a `while True`. The subsequent wait
call on the teamd container very likely returns immediately, and it calls
`is_warm_restart_enabled` and `is_fast_reboot_enabled`. In either of these
cases, sometimes, there is a crash in the transition from C code to Python code
(after the function gets executed). Python sees that this thread got a signal
to exit, because the main thread is exiting, and tells pthread to exit the
thread. However, during the stack unwinding, _something_ is telling the
unwinder to call `std::terminate`. The reason is unknown.
This then results in a python3 SIGABRT, and systemd then doesn't call the stop
script to actually stop the container (possibly because the main process exited
with a SIGABRT, so it's a hard crash). This means that the container doesn't
actually get stopped or restarted, resulting in an inconsistent state
afterwards.
The workaround appears to be that if we know the main thread needs to exit,
just return here, and don't continue execution. This at least tries to avoid it
from getting into the problematic code path. However, it's still feasible to
get a SIGABRT, depending on thread/process timings (i.e. teamd exits, signals
the main thread to exit, and then syncd exits, and syncd calls one of the two C
functions, potentially hitting the issue).

- Why I did it
interfaces-config service restarts networking service, during the restart loopback interface address is being removed and reassigned back, leaving loopback without an ipv4 address for a while.
On SONiC startup and config reload interfaces-config and bgp services start in parallel and sometimes
fpmsyncd in bgp attempts bind to loopback while it does not have an address, fails with the log
Exception "Cannot assign requested address" had been thrown in daemon
and exits with rc 0.
root@sonic:/# supervisorctl status
fpmsyncd EXITED Jul 20 05:04 AM
zebra RUNNING pid 35, uptime 6:15:05
zsocket EXITED Jul 20 05:04 AM
docker logs bgp
INFO exited: fpmsyncd (exit status 0; expected)
With fpmsyncd dead, configured routes do not appear in the database.
- How I did it
Added ordering dependency on interfaces-config service into bgp.config
- How to verify it
Itself the issue reproduces quite rarely, but one can gain the time interval between networking down and networking up in interfaces-config.sh like this:

Multi-asic Docker instances are created behind Docker's default bridge
which doesn't allow talking to other Docker instances that are in the
host network (like database-chassis).
On linecards, we configure midplane interfaces to let per-asic docker
containers talk to CHASSIS_DB on the supervisor through internal chassis
network.
On the supervisor we don't need to use chassis internal network, but we
still need a similar setup in order to allow fabric containers to talk
to database-chassis
The timer execution may fail if triggered during a config reload
(when the sonic.target is stopped). This might happen in a rare
situation if config reload is executed after reboot in a small
time slot (for 0 to 30 seconds) before the tacacs-config timer
is triggered. To ensure that timer execution will be resumed after
a config reload the WantedBy section of the systemd service is updated
to describe relation to sonic.target.

Why I did it
If the SWSS services was restarted, the MACsec service should also be restarted. Otherwise the data in wpa_supplicant and orchagent will not be consistent.
How I did it
Add dependency in docker-macsec.mk.
How to verify it
Manually check by 'sudo service swss restart'.
The MACsec container should be started after swss, the syslog will look like

It could happen that a container has already crashed but docker-wait-any
will wait forever till it starts. It should, however, immediately exit
to make the serivce restart.
#### Why I did it
It is observed in some circumstances that the auto-restart mechanism does not work. Specifically for ```swss.service```, ```orchagent``` had crashed before ```docker-wait-any``` started in ```swss.sh```. This led ```docker-wait-any``` wait forever for ```swss``` to be in ```"Running"``` state and it results in:

The check for ```"Running"``` state is not needed because for cold boot case we do ```start_peer_and_dependent_services``` and for warm boot case the loop will retry to wait for container if this container is doing warm boot:
d01a91a569/files/image_config/misc/docker-wait-any (L56)
#### How I did it
Removed the check for ```"Running"```.
#### How to verify it
Kill swss before ```docker-wait-any``` is reached and verify auto restart will restart swss serivce.

Why I did it
On a supervisor card in a chassis, syncd/teamd/swss/lldp etc dockers are created for each Switch Fabric card. However, not all chassis would have all the switch fabric cards present. In this case, only dockers for Switch Fabrics present would be created.
The monit 'container_checker' fails in this scenario as it is expecting dockers for all Switch Fabrics (based on NUM_ASIC defined in asic.conf file).
Why I did:
In case of multi-asic platforms gbsyncd is not getting added to Feature Table of Host Config DB. Without this container_checker complains of not needed gbsyncd container's are running.
How I did:
Update Both Host and Namespace config db when gbsyncd docker is starting.
How I verify:
Verified on Multi-asic platforms.
Change `sxdkernel start` to `sxdkernel restart`. If `syncd` service crashes in `ExecStartPre` systemd will not call `ExecStop` and thus will not call `sxdkernel stop`. Use of `sxdkernel restart` is more robust in terms of guarantees to restore the system after unexpected crashes.

bgp should be a per-asic service, and runs for each namespace on
multi-asic platforms. However, putting bgp in MULTI_INST_DEPENDENT
causes swss to be restarted as well as bgp. this is causing issues after #11000
Issue: #11653
This fix:
removes bgp from dependents list
adds a conditional that either adds bgp, or bgp@$DEV to separate
between single and multi-asic platforms
When using trap on SIGTERM the script will not react to the SIGTERM signal sent while a child is executing.
I.e, the following script does not react on SIGTERM sent to it if it is
waiting for sleep to finish:
```
trap "echo Handled SIGTERM" 0 2 3 15
echo "Before sleep"
sleep inf
echo "After sleep"
```
Instead, trap only on EXIT which covers also a scenario with exit on
SIGINT, SIGTERM.

In arp_update, check for FAILED or INCOMPLETE kernel neighbor entries and manually ping them to try and resolve the neighbor
Signed-off-by: Lawrence Lee <lawlee@microsoft.com>
Why I did it
The initial value has to be present for the state machines to work. In active-standby dual-tor scenario, or any hardware mux scenario, the value will be updtaed eventually with a delay.
However, in active-active dual-tor scenario, there is no other mechanism to initialize the value and get state machines started.
So this script will have to write something at start up time.
For active-active dualtor, 'active' is a more preferred initial value, the state machine will switch the state to standby soon if
link prober found link not in good state.
How I did it
Update the script to always provide initial values.
How to verify it
Tested on active-active dual-tor testbed.

Why I did it:
bgp container was not restarting on swss crash. When swss crashes, linkmgrd
doesn't initate a switchover because it cannot access the default route from
orchagent. Bringing down bgp with swss will isolate the ToR, causing linkmgrd
to initiate a switchover to the peer ToR avoiding significant packet loss.

How I did it
Add a flag require_global_dscp_to_tc_map to control whether to generate the PORT_QOS_MAP|global entry. The default value for require_global_dscp_to_tc_map is true. If the device type is storage backend, the value is changed to false. Then the PORT_QOS_MAP|global entry is not generated.
How to verify it
Update the current test_qos_dscp_remapping_render_template to cover storage backend.
Refactors the SONiC Installer to support greater flexibility in building for a given architecture and bootloader.
#### Why I did it
Currently the SONiC installer assumes that if a platform is ARM based that it uses the `uboot` bootloader and uses the `grub` bootloader otherwise. This is not a correct assumption to make as ARM is not strictly tied to uboot and x86 is not strictly tied to grub.
#### How I did it
To implement this I introduce the following changes:
* Remove the different arch folders from the `installer/` directory
* Merge the generic components of the ARM and x86 installer into `installer/installer.sh`
* Refactor x86 + grub specific functions into `installer/default_platform.conf`
* Modify installer to call `default_platform.conf` file and also call `platform/[platform]/patform.conf` file as well to override as needed
* Update references to the installer in the `build_image.sh` script
* Add `TARGET_BOOTLOADER` variable that is by default `uboot` for ARM devices and `grub` for x86 unless overridden in `platform/[platform]/rules.mk`
* Update bootloader logic in `build_debian.sh` to be based on `TARGET_BOOTLOADER` instead of `TARGET_ARCH` and to reference the grub package in a generic manner
#### How to verify it
This has been tested on a ARM test platform as well as on Mellanox amd64 switches as well to ensure there was no impact.

However, there is no lossy PG profile for the T2 facing ports on T1. The lossless PGs for ports between T1 and T0 have been handled by buffermgrd .Therefore, We need to add lossy PG profiles for T2 facing ports on T1.
We don't have this issue on T0 because PG 2 and PG 6 are lossless PGs, and there is no lossy traffic mapped to PG 2 and PG 6
Map port level TC7 to PG0
Before the PCBB change, DSCP48 -> TC 6 -> PG 0.
After the PCBB change, DSCP48 -> TC 7 -> PG 7
Actually, we can map TC7 to PG0 to save a lossy PG.
How I did it
Update the qos and buffer template.
How to verify it
Verified by UT.
