I found that with IPv4Network types, calling list(ip_ntwrk.hosts()) is reliable. However, when doing the same with an IPv6Network, I found that the conversion to a list can hang indefinitely. This appears to me to be a bug in the ipaddress.IPv6Network implementation. However, I could not find any other reports on the web.
This patch changes the behavior to call next() on the ip_ntwrk.hosts() generator instead, which returns the IP address of the first host.
Fix hostcfgd so that changes to the "FEATURE" table in ConfigDB are properly handled. Three changes here:
1. Fix indenting such that the handling of each key actually occurs in the for key in status_data.keys(): loop
2. Add calls to sudo systemctl mask and sudo systemctl unmask as appropriate to ensure changes persist across reboots
3. Substitute returns with continues so that even if one service fails, we still try to handle the others
Note that the masking is persistent, even if the configuration is not saved. We may want to consider only calling systemctl enable/disable in hostcfgd when the DB table changes, and only call systemctl mask/unmask upon calling config save.

* fix typo
* further refactoring
* use sonic-db-cli instead
Since the introduction of VRF, interface-related tables in ConfigDB will have multiple entries, one of which only contains the interface name and no IP prefix. Thus, when iterating over the keys in the tables, we need to ignore the entries which do not contain IP prefixes.
and then we load image and reboot even if there was existing
config_db.json we will look for DHCP Service. we should disbale
update_graph in such cases. This behaviour is silimar to what we have in
201811 image.
Modified caclmgrd behavior to enhance control plane security as follows:
Upon starting or receiving notification of ACL table/rule changes in Config DB:
1. Add iptables/ip6tables commands to allow all incoming packets from established TCP sessions or new TCP sessions which are related to established TCP sessions
2. Add iptables/ip6tables commands to allow bidirectional ICMPv4 ping and traceroute
3. Add iptables/ip6tables commands to allow bidirectional ICMPv6 ping and traceroute
4. Add iptables/ip6tables commands to allow all incoming Neighbor Discovery Protocol (NDP) NS/NA/RS/RA messages
5. Add iptables/ip6tables commands to allow all incoming IPv4 DHCP packets
6. Add iptables/ip6tables commands to allow all incoming IPv6 DHCP packets
7. Add iptables/ip6tables commands to allow all incoming BGP traffic
8. Add iptables/ip6tables commands for all ACL rules for recognized services (currently SSH, SNMP, NTP)
9. For all services which we did not find configured ACL rules, add iptables/ip6tables commands to allow all incoming packets for those services (allows the device to accept SSH connections before the device is configured)
10. Add iptables rules to drop all packets destined for loopback interface IP addresses
11. Add iptables rules to drop all packets destined for management interface IP addresses
12. Add iptables rules to drop all packets destined for point-to-point interface IP addresses
13. Add iptables rules to drop all packets destined for our VLAN interface gateway IP addresses
14. Add iptables/ip6tables commands to allow all incoming packets with TTL of 0 or 1 (This allows the device to respond to tools like tcptraceroute)
15. If we found control plane ACLs in the configuration and applied them, we lastly add iptables/ip6tables commands to drop all other incoming packets
* Changes for LLDP for Multi NPU Platoforms:-

* Run fsck filesystem check support prior mounting filesystem
If the filesystem become non clean ("dirty"), SONiC does not run fsck to
repair and mark it as clean again.
This patch adds the functionality to run fsck on each boot, prior to the
filesystem being mounted. This allows the filesystem to be repaired if
needed.
Note that if the filesystem is maked as clean, fsck does nothing and simply
return so this is perfectly fine to call fsck every time prior to mount the
filesystem.
How to verify this patch (using bash):
Using an image without this patch:
Make the filesystem "dirty" (not clean)
[we are making the assumption that filesystem is stored in /dev/sda3 - Please adjust depending of the platform]
[do this only on a test platform!]
dd if=/dev/sda3 of=superblock bs=1 count=2048
printf "$(printf '\\x%02X' 2)" | dd of="superblock" bs=1 seek=1082 count=1 conv=notrunc &> /dev/null
dd of=/dev/sda3 if=superblock bs=1 count=2048
Verify that filesystem is not clean
tune2fs -l /dev/sda3 | grep "Filesystem state:"
reboot and verify that the filesystem is still not clean
Redo the same test with an image with this patch, and verify that at next reboot the filesystem is repaired and becomes clean.
fsck log is stored on syslog, using the string FSCK as markup.
The one big bgp configuration template was splitted into chunks.
Currently we have three types of bgp neighbor peers:
general bgp peers. They are represented by CONFIG_DB::BGP_NEIGHBOR table entries
dynamic bgp peers. They are represented by CONFIG_DB::BGP_PEER_RANGE table entries
monitors bgp peers. They are represented by CONFIG_DB::BGP_MONITORS table entries
This PR introduces three templates for each peer type:
bgp policies: represent policieas that will be applied to the bgp peer-group (ip prefix-lists, route-maps, etc)
bgp peer-group: represent bgp peer group which has common configuration for the bgp peer type and uses bgp routing policy from the previous item
bgp peer-group instance: represent bgp configuration, which will be used to instatiate a bgp peer-group for the bgp peer-type. Usually this one is simple, consist of the referral to the bgp peer-group, bgp peer description and bgp peer ip address.
This PR redefined constant.yml file. Now this file has a setting for to use or don't use bgp_neighbor metadata. This file has more parameters for now, which are not used. They will be used in the next iteration of bgpcfgd.
Currently all tests have been disabled. I'm going to create next PR with the tests right after this PR is merged.
I'm going to introduce better bgpcfgd in a short time. It will include support of dynamic changes for the templates.

[sonic-yang-models]: First version of yang models for Port, VLan, Interface, PortChannel, loopback and ACL.
YANG models as per Guidelines.
Guideline doc: https://github.com/Azure/SONiC/blob/master/doc/mgmt/SONiC_YANG_Model_Guidelines.md
[sonic-yang-models/tests]: YANG model test code and JSON input for testing.
[sonic-yang-models/setup.py]: Build infra for yang models.
**- What I did**
Created Yang model for Sonic.
Tables: PORT, VLAN, VLAN_INTERFACE, VLAN_MEMBER, ACL_RULE, ACL_TABLE, INTERFACE.
Created build infra files using which a new package (sonic-yang-models) can be build and can be deployed on sonic switches. Yang models will be part of this new package.
**- How I did it**
Wrote yang models based on Guideline doc:
https://github.com/Azure/SONiC/blob/master/doc/mgmt/SONiC_YANG_Model_Guidelines.md
and
https://github.com/Azure/SONiC/wiki/Configuration.
Wrote python wheel Package infra which runs test for these Yang models using a json files which consists configuration as per yang models. These configs are for negative tests, which means we want to test that most must condition, pattern and when condition works as expected.

sonic-netns-exec fails to execute below command in swss.sh:

for j,name in ipairs(matches) do
redis.call('DEL', name)
end
end" 0
This command fails with error " redis.exceptions.ResponseError: value is not an integer or out of range" .
Root cause:
When sonic-netns-exec executes the above function, argument passed to sonic-db-cli is NOT executed as a single script.
The argument is passed as separate keywords to sonic-db-cli, as below:
['EVAL', 'local', 'tables', '=', "{'PORT_TABLE*'}", 'for', 'i', '=', '1,', 'table.getn(tables)', 'do', 'local', 'matches', '=', "redis.call('KEYS',", 'tables[i])', 'for', 'j,name', 'in', 'ipairs(matches)', 'do', "redis.call('DEL',", 'name)', 'end', 'end', '0']
- How I did it
To make sure that the parameters are passed as they were set initially, fix sonic-netns-exec to use double quoted "$@", where "$@" is "$1" "$2" "$3" ... "${N}"
After fix, the argument passed to sonic-db-cli is as below:
Argument passed to sonic-db-cli:
['EVAL', "\n local tables = {'PORT_TABLE*'}\n for i = 1, table.getn(tables) do\n local matches = redis.call('KEYS', tables[i])\n for j,name in ipairs(matches) do\n redis.call('DEL', name)\n end\n end", '0']

- What I did
Add configuration to avoid ntpd from panic and exit if the drift between new time and current system time is large.
- How I did it
Added "tinker panic 0" in ntp.conf file.
- How to verify it
[this assumes that there is a valid NTP server IP in config_db/ntp.conf]
Change the current system time to a bad time with a large drift from time in ntp server; drift should be greater than 1000s.
Reboot the device.

3. upon reboot, ntp-config service comes up fine, ntp service goes to active(exited) state without any error message. This is because the offset between new time (from ntp server) and the current system time is very large, ntpd goes to panic mode and exits. The system continues to show the bad time.
After the fix:
3. Upon reboot, ntp-config comes up fine, ntp services comes up from and stays in active (running) state. The system clock gets synced with the ntp server time.
Take advantage of an SDK environment variable to customize the location where sdk_socket exists.
In the latest SDK sdk_socket has been moved from /tmp to /var/run which is a better place to contain this kind of file.
However, this prevents the subdirs under /var/run from being mapped to different volumes. To resolve this, we take advantage of an SDK variable to designate the location of sdk_socket.
This requires every process that requires to access sdk_socket have this environment variable defined. However, to define environment variable for each process is less scalable. We take advantage of the docker scope environment variable to avoid that.
It depends on PR 4227
Instead of updating hostname manualy on Config DB hostname change,
simply share containers UTS namespace with host OS.
Ideally, instead of setting `--uts=host` for every container in SONiC,
this setting can be set per container if feature requires.
One behaviour change is introduced in this commit, when `--privileged`
or `--cap-add=CAP_SYS_ADMIN` and `--uts=host` are combined, container
has privilege to change host OS and every other container hostname.
Such privilege should be fixed by limiting containers capabilities.

Fix the issue of incorrectly skipping the convertfs hook when fast-reboot from EOS, by adding an extra kernel cmdline param "prev_os" to differentiate fast-reboot from EOS and from SONiC.
This is because we still do disk conversion for fast reboot from eos to sonic, like format the disk.

This is an addendum to #3958, which also instructs apt to ignore the "Valid Until" date in Release files inside the slave containers, making a complete solution, much like the previously abandoned PR #2609. This patch also unifies file names and contents.
When the Debian team archives a repo, it stops updating the "Valid Until" date, thus apt-get will not apply updates for that repo unless we explicitly tell it to ignore the "Valid Until" date. Also, this has become an issue with active (i.e., non-archived) repos twice in the past year because the Debian folks seem to occasionally let the expiration lapse before updating the date. This will cause SONiC builds to fail with a message like E: Release file for http://debian-archive.trafficmanager.net/debian-security/dists/jessie/updates/InRelease is expired (invalid since 3d 3h 11min 20s). Updates for this repository will not be applied. until the dates have been updated and propagated to all mirrors. With this patch, SONiC should no longer be affected by lapsed "Valid Until" dates, whether they be accidental or purposeful.

Prior to this change, `build_debian.sh` would generate a Debian
filesystem in `./fsroot`. This needs root permissions, and one of the
tests that is performed is whether the user can create a character
special file in the filesystem (using mknod).
On most NFS deployments, `root` is the least privileged user, and cannot
run mknod. Also, attempting to run commands like rm or mv as root would
fail due to permission errors, since the root user gets mapped to an
unprivileged user like `nobody`.
This commit changes the location of the Debian filesystem to `/fsroot`,
which is a tmpfs mount within the slave Docker. The default squashfs,
docker tarball and zip files are also created within /tmp, before being
copied back to /sonic as the regular user.
The side effect of this change is that the contents of `/fsroot` are no
longer available once the slave container exits, however they are
available within the squashfs image.

Delay CPU intensive services at boot
- How I did it
Made snmp.timer work and add telemetry.timer.
But this is not enough because it breaks the existing snmp dependency on swss.
So, in this solution snmp timer is a wanted by swss service, but since OnBootSec timer expires only once it will not trigger snmp service, so I added line "OnUnitActiveSec=0 sec" which will start snmp service based on the last time it was active. On boot only OnBootSec will expire, on swss start/restarts only second timer will expire immediately and trigger snmp service.
However, snmp service will not stop after "systemctl stop snmp" because of the second timer which will always expire when snmp service because unavailable.
So there is a conflict which will be handled by systemd if we add "Conflicts=" line to both snmp.service and snmp.timer.
So during boot:
snmp does not start by default
swss starts and starts snmp timer
OnUnitActiveSec=0 does not expire since there is no snmp active
OnBootSec expires and starts snmp service and snmp timer gets stopped
During "systemctl restart swss"
snmp stops because of Requisite on swss
snmp unblocks snmp timer from running
swss starts and starts snmp timer
OnUnitActiveSec=0 expires imidiately and start snmp which stops snmp timer
During "systemctl stop snmp"
stop of snmp service unblocks snmp timer but no one starts the timer so it is not started by "OnUnitActiveSec=0"
If we need to stop swss during fast-reboot procedure on the boot up path,
it means that something went wrong, like syncd/orchagent crashed already,
we are stopping and restarting swss/syncd to re-initialize. In this case,
we should proceed as if it is a cold reboot.

2) The service is disabled on boot. One may enable explicitly.
3) The .rc file to be updated with acct credentials and http proxy to use.
4) If service is enabled with no credentials, it would sleep, with periodic log messages
5) For any update in .rc, the service has to be restarted to take effect.

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.
* Create a SONiC configuration management service
* Perform config db migration after loading config_db.json to redis DB
* Migrate config-setup post migration hooks on image upgrade
config-setup post migration hooks help user to migrate configurations from
old image to new image. If the installed hooks are user defined they will not
be part of the newly installed image. So these hooks have to be migrated to
new image and only then they can be executing when the new image is booting.
The changes in this fix migrate config-setup post-migration hooks and ensure
that any hooks with the same filename in newly installed image are not
overwritten.
It is expected that users install new hooks as per their requirement and
not edit existing hooks. Any changes to existing hooks need to be done as
part of new image and not post bootup.

The sflow service should not start unless the swss service is started. However, if this service is not started, the sflow service should not attempt to start them, instead it should simply fail to start. Using Requisite=, we will achieve this behavior, whereas using Requires= will cause the required service to be started.
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.
