Re: [lwip-users] PPP new Stack

Hi Sylvain,

Ok I think I found the problem. I use PPP_INPROC_OWNTHREAD and once I added 
ppp_delete() to the end it seems to fix the problem.
I also removed the ppp_delete from the linkStatusCB. Somehow a clean up wasn’t 
completed and a pbuf was always allocated but not freed as you can here:

ppp_link_terminated: unit 2: link_status_cb=0xe15 err_code=5
PPP Error=5
ppp_delete: unit 2
netif: setting default interface ''
netif_remove: removed netif
ppp_link_terminated: finished.
pbuf_free(0x1000255c)
pbuf_free: deallocating 0x1000255c
pbuf_alloc(length=0)
pbuf_alloc: allocated pbuf 0x1000255c     <---- here
pbuf_alloc(length=0) == 0x1000255c
Delete pppos_input_thread

Below is my proc.

#if !PPP_INPROC_OWNTHREAD
/* Define this process here as we need to delete the task when the 
connections ends */
static void pppos_input_thread( void *arg   ){
int count;
 ppp_pcb_rx *pcrx = (ppp_pcb_rx*)arg;
 ppp_pcb *pcb = (ppp_pcb*)pcrx->pcb;
 memset(rxbuf,0,PPPOS_RX_BUFSIZE);

 while (pcb->phase != PHASE_DEAD) {
   count = sio_read(pcrx->fd, rxbuf, PPPOS_RX_BUFSIZE);
   if(count > 0) {
     pppos_input(pcb, rxbuf, count);
   }else {
     /* nothing received, give other tasks a chance to run */
     sys_msleep(1);
   }
 }

 ppp_delete(pcb);
 puts("Delete pppos_input_thread\n");
 vTaskDelete(NULL);

}

#endif
