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
1. ebtables -t filter -A FORWARD -p 802_1Q --vlan-encap 0806 -j DROP
The ARP packet with vlan tag can't match the default rule.

* 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.
FIX:: #4231
- create a file in files/image_config/ntp/ntp-systemd-wrapper to add mgmt vrf related start cmd for ntp service. So that the default /usr/lib/ntp/ntp-systemd-wrapper can be overriden during build time.
- modify build_debian.sh to cp files/image_config/ntp/ntp-systemd-wrapper to /usr/lib/ntp/ntp-systemd-wrapper during build time.

- 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.
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.

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.
