  • Fix bug where "name" field of interface_info struct was improperly getting overwritten in _bridgefdbquery(). Under certain circumstances (like upon receiving a unicast DHCP renewal message), the stored interface's name could be overwritten by a different interface's name, breaking the relay agent's ability to properly relay packets for the remainder of the process' lifetime.

  • Unrelated changes:

    • Define circuit_id and remote_id fields of interface_info struct as 64-byte char arrays instead of pointers. Previously, the circuit_id pointer was getting updated to a pointer of a buffer on the stack, and thus would almost always contain garbage. This would prevent matching an interface by its circuit ID (if that behavior is so desired)
    • Minor cleanup and tweaks to buffer sizes and some logic to ensure consistent behavior (and make code more understandable). Although they were not causing problems now, they could have potentially done so in the future
    • Removed whitespace from empty lines
    • Generate patch file using git format-patch and apply using git apply instead of diff -ruN/patch -p1 to align with most other patch generation/application in the SONiC project

- Also fix Python 3-related issues:
    - Use integer (floor) division in config_samples.py (sonic-config-engine)
    - Replace print statement with print function in eeprom.py plugin for x86_64-kvm_x86_64-r0 platform
    - Update all platform plugins to be compatible with both Python 2 and Python 3
    - Remove shebangs from plugins files which are not intended to be executable
    - Replace tabs with spaces in Python plugin files and fix alignment, because Python 3 is more strict
    - Remove trailing whitespace from plugins files

…ble (sonic-net#1224)

- What I did
Updates to bgp config and show commands with the movement of internal bgp sessions to a new table BGP_INTERNAL_NEIGHBOR table.
With the introduction of BGP_INERNAL_NEIGHBOR table, the user cannot start/stop/remove internal neighbors which I feel is not needed as these internal bgp sessions which are supposed to be UP always.

- How I did it
Updated the show/bgp util so that it gets the internal bgp sessions from BGP_INTERNAL_NEIGHBOR table.
Removed the API's to get the local_as in config/bgp which is not required now.

- How to verify it
Made sure that the output remain same with the new internal bgp neighbor table.
