Hi,

I suspect that my network driver has memory leaks.
I read about malloc_g, but, it looks like malloc_g can replace the malloc
and not the
->alloc
->alloc_down_npkt

alloc_up_npkt

  1. am i right?
  2. is there any tool to check memory leaks for allocation made from the
    io_net_self_t allocation functions?

Hi,
May be you have taken care of it but let me confirm.Are you calling the
reg_tx_done() ? You are responsible for deallocating the packet when it is
transmitted out.I had faced this problem once.Make sure you have to have a
reg_tx_done() call for a corresponding alloc_down/up_npkt().In the
rx_done.You might even try to post the code snippet here so that people can
figure out any problems.


Hope it helps

Sreekanth,

I’ve done already reg_tx_done() && tx_done.
Also I’m using the allocation function that you mentioned too.

any more ideas?
