[RP-PPPoE] RP-PPPoE Memory Leak?

[Daniel Le]

Hello,

Has anyone come across a memory leak in the following scenarios? If so, could you share what you've done to address the issue?

- Bring up a successful PPPoE connection then tear it down.
- Force a PPPoE connection setup failure with incorrect authentication credentials.

I ran valgrind and found memory leak in both cases.

After I tried to fix what valgrind pointed out (example output of valgrind results below), the "top" program or another tool I have to check system memory usage still indicates memory leak.

Passed PPP authentication
