Description (partial)

Symptom:
Thanks Chang and Bo's comments. I'm going to raise a CDETS to capwap of click for tracking if no objection.
 
Thanks,
Fan
 

 
We saw this problem multiple times before, on both Corsica and Barbados platforms. I remember the root cause were all from the radio driver.
 
Based on the error message, the calculated expected packet length was like 0x7100 ? this is definitely wrong. The actual management frame was only 18 bytes, even shorter than the expected mgmt hdr.
 
Sincerely,
Bo Yang
 
 

 
This is from the following code. Looks like flexconnect related.
 
ANQPResponder::simple_action(Packet *p)
 

604        // check p_length() against req->len
605        uint8_t *data = p_data + GAS_INITIAL_REQUEST_SIZE;
606        if (p->length() - sizeof(struct click_wifi) - GAS_INITIAL_REQUEST_SIZE < req.len) {
607            click_chatter("%s packet too short (expected 0x%x, payload %x)",
608                            __func__,
609                            req.len,
610                            (unsigned int) (p->length() - sizeof(struct click_wifi) - GAS_INITIAL_REQUEST_SIZE));
611            return p;
612        }

Hi all,
 
On 8.8.1.99 load, a 1542 mesh AP showing below error. Known issue?
 
Thanks,
