* fix the memory leak in on_pmpe. objects created via sx_api having convention new_<type_name> should be release explicitly via delete_<type_name>.
* avoid duplicate code.
* fix fast reboot compatibility
We should handle both cases for backward-compatible with 201803:
- fast-reboot
- SONIC_BOOT_TYPE=fast-reboot
* handle review comments
* add a comment that getBootType code snippet is shared between two files
- What I did
Configure sshd to close all SSH connetions after 15 minutes of inactivity.
- How I did it
Set ClientAliveInterval to 900 (900 seconds = 15 minutes) and ClientAliveCountMax to 0
in /etc/ssh/sshd_config using augtool in build_debian.sh. In the process, I refactored the existing augtool command for sshd_config so as to add comments and empty lines to file for readability.
- How to verify it
Log into device via management port. Wait 15 minutes without sending a keystroke -- you should be automatically logged out.
2) Install debug tools in every debug docker image
3) Install available debug symbols in debug docker image
4) Provide additional host/docker mapping for host dirs /src & /debug
4.1) The one-image will have source code under /src
4.2) /debug is mapped as rw. User can put his core file there and use this dir to
collect debug session logs too.
5) Build debug image using debug dockers
6) Source code is archived into /src of debug image
7) The welcome banner is extended to display these additional facilities in debug image.
Upgrade the version of rsyslog installed in Docker containers to the latest version available from jessie-backports repo (currently 8.23.0-2~bpo). Based off my change to the 201803 branch (#2709). This should eliminate some memory leaks and will prevent any regressions if moving from the 201803 branch to the 201811 branch.
* [submodule] update sonic-linux-kernel (#2985)
* Fix many version strings
* Update minor version
* Update arista-drivers submodule (#9)
* Rebuild SDK on new kernel (#10)
* Set the default mac ageing time to 300 seconds
The current mac ageing was disabled, this could lead the mac address
table to increase over time and lead to resource and performance issues.

* Update the default HW ageing timer to be 600 seconds.
This is to be on the safer side where ARP update interval
is 300 seconds and SONiC does not flood when ARP is aged out.

- What I did
Currently when the system is under memory pressure, the OOM killer kicks in and kills a rogue process. Killing a rogue process can cause the device to be un-healthy leading to blackholing of the traffic.
To avoid this, configure the OOM to do a kernel panic which will cause the device to reboot and come back up healthy.
- How I did it
Added the sysctl variable panic_on_oom and set the value to 2.
Setting it to 2 will ensure OOM killer to always do a kernel panic.

* [logrotate] Decrease frequency to every 10 minutes; kill any lingering logrotate processes
* [logrotate] Delete all *.1.gz files as firstaction; Remove note about init-system-helpers < 1.47 workaround
However, continue to send SIGHUP directly to rsyslogd process
because 'service rsyslog rotate' still doesn't work properly with
init-system-helpers version 1.48
