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:-
a) Enable LLDP for Host namespace for Management Port
b) Make sure Management IP is avaliable in per asic namespace
needed for LLDP Chassis configuration
c) Make sure chassis mac-address is correct in per asic namespace
d) Do not run lldp on eth0 of per asic namespace and avoid chassis
configuration for same
e) Use Linux hostname instead from Device Metadata for lldp chassis
configuration since in multi-npu platforms device metadata hostname
will be differnt

* 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.
**- How to verify it**

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.
Before the fix:
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.
