net: ravb: Count packets instead of descriptors in GbEth RX path

2024-02-15T15:55:30+00:00

The units of "work done" in the RX path should be packets instead of
descriptors, as large packets can be spread over multiple descriptors.

pppoe: Fix memory leak in pppoe_sendmsg()

2024-02-15T15:50:32+00:00

syzbot reports a memory leak in pppoe_sendmsg [1].

The problem is in the pppoe_recvmsg() function that handles errors
in the wrong order. For the skb_recv_datagram() function, check
the pointer to skb for NULL first, and then check the 'error' variable,
because the skb_recv_datagram() function can set 'error'
to -EAGAIN in a loop but return a correct pointer to socket buffer
after a number of attempts, though 'error' remains set to -EAGAIN.

skb_recv_datagram
      __skb_recv_datagram          // Loop. if (err == -EAGAIN) then
                                   // go to the next loop iteration
          __skb_try_recv_datagram  // if (skb != NULL) then return 'skb'
                                   // else if a signal is received then
                                   // return -EAGAIN
