TX Port Mon Feature Implemented #1

vivekrnv · 2021-02-28T05:51:56Z

What I did
Added implementation for Tx Port Monitoring feature.

Why I did it
To Complete Lab-5 as a part of new employee training

How I verified it
Manual testing using CLI commands, which are written in sonic-utilities repo. Used redis-cle & Counter DB to simulate Tx Error counts

Details if related

TxPortMon class inherits from Orch
Selectable Timer is used to invoke the class at the end of pooling period
Changes in Config are listed to for <interface,threshold> & pooling changes
An internal Hash Map is used to Store the State Information for interfaces
State Information and other data in periodically pushed to State DB

Currently, ASAN sometimes reports the BufferOrch::m_buffer_type_maps and QosOrch::m_qos_maps as leaked. However, their lifetime is the lifetime of a process so they are not really 'leaked'. This also adds a simple way to add more suppressions later if required. Example of ASAN report: Direct leak of 48 byte(s) in 1 object(s) allocated from: #0 0x7f96aa952d30 in operator new(unsigned long) (/usr/lib/x86_64-linux-gnu/libasan.so.5+0xead30) #1 0x55ca1da9f789 in __static_initialization_and_destruction_0 /__w/2/s/orchagent/bufferorch.cpp:39 #2 0x55ca1daa02af in _GLOBAL__sub_I_bufferorch.cpp /__w/2/s/orchagent/bufferorch.cpp:1321 #3 0x55ca1e2a9cd4 (/usr/bin/orchagent+0xe89cd4) Direct leak of 48 byte(s) in 1 object(s) allocated from: #0 0x7f96aa952d30 in operator new(unsigned long) (/usr/lib/x86_64-linux-gnu/libasan.so.5+0xead30) #1 0x55ca1da6d2da in __static_initialization_and_destruction_0 /__w/2/s/orchagent/qosorch.cpp:80 #2 0x55ca1da6ecf2 in _GLOBAL__sub_I_qosorch.cpp /__w/2/s/orchagent/qosorch.cpp:2000 #3 0x55ca1e2a9cd4 (/usr/bin/orchagent+0xe89cd4) - What I did Added an lsan suppression config with static variable leak suppression - Why I did it To suppress ASAN false positives - How I verified it Run a test that produces the static variable leaks report and checked that report has these leaks suppressed.
