Patrick McHardy writes: > Looks like hdrlen is uninitialized in ppp_async. This patch No, it is initialized by the memset at line 165, and 0 is the correct value for ap->chan.hdrlen, since the ppp_async driver doesn't prepend any bytes to the skb on transmit. The bug must be somewhere else. It would be very interesting to know what value pf->hdrlen has in ppp_write and how it got that value though. Paul. |
