Asic PCI ID (PCI address) is collected by chassisd (inside pmon -
Azure/sonic-platform-daemons#175) and saved in CHASSIS_STATE_DB (in
redis_chassis). CHASSIS_STATE_DB is accessible by swss containers.
At docker-init.sh (script is called after swss container is created and before
anything that could run in swss like orchagent...), we wait until asic PCI ID
of the corresponding asic is populated by chassisd. We then update asic_id in
CONFIG_DB of asic's database.
A system supporting dynamic asic PCI ID identification requires to have a file
(empty) use_pci_id_chassis in its platform dir.
When orchagent runs, it has correct asic PCI ID in its CONFIG_DB.

- Use the `wait_for_link.sh` script to delay ndppd start until after the VLAN interface is ready
- Avoids issue where ndppd tries to change interface attributes before the interface is ready

Implement infrastructure that allows enabling address sanitizer
for docker containers. Enable address sanitizer for SWSS container.
- Why I did it
To add a possibility to compile SONiC applications with address sanitizer (ASAN).
ASAN is a memory error detector for C/C++. It finds:
1. Use after free (dangling pointer dereference)
2. Heap buffer overflow
3. Stack buffer overflow
4. Global buffer overflow
5. Use after return
6. Use after the scope
7. Initialization order bugs
8. Memory leaks
- How I did it
By adding new ENABLE_ASAN configuration option.
- How to verify it
By default ASAN is disabled and the SONiC image is not affected.
When ASAN is enabled it inspects all allocation, deallocation, and memory usage that the application does in run time. To verify whether the application has memory errors tests that trigger memory usage of the application should be run. Ideally, the whole regression tests should be run. Memory leaks reports will be placed in /var/log/asan/ directory of SONiC host OS.
