Re: [lwip-devel] Check netif pointer before calling status callback

[Dirk Ziegelmeier]

The code is only called in places where there should be no invalid pointer in "n". Did you find a place where the pointer can be invalid?

Hi

Current implementation of  NETIF_STATUS_CALLBACK

is as follows:

#if LWIP_NETIF_STATUS_CALLBACK

#define NETIF_STATUS_CALLBACK(n) do{ if (n->status_callback) { (n->status_callback)(n); }}while(0)

#else

#define NETIF_STATUS_CALLBACK(n)

#endif /* LWIP_NETIF_STATUS_CALLBACK */

​Is there any specific reason that there is no check for valid "n" pointer ?

A check is good to have.

​

Thanks & Best Regards,
