[lwip-users] PPP new Stack

[Nikolas Karakotas]

Hello Sylvain,

 

I have been using latest ppp-new commit from git and also lwip but im experiencing a problem ONLY when I close the ppp connection. When the ppp thread is left open (running always) everything is OK. Let me explain to you what happens:

 

I initiate a connection and once the link is up I send my data.

I then close the connection and use ppp_delete().

After around 5 tries it seems that I get an LCP timeout. This occurs because I don’t have any pbuf available.

It seems that there might be a memory leak when closing the connection and deleting ppp?

 

I have attached serial output.

 

Regards,

Nick
