rxrpc: Emit BUSY packets when supposed to rather than ABORTs
In the input path, a received sk_buff can be marked for rejection by setting RXRPC_SKB_MARK_* in skb->mark and, if needed, some auxiliary data (such as an abort code) in skb->priority. The rejection is handled by queueing the sk_buff up for dealing with in process context. The output code reads the mark and priority and, theoretically, generates an appropriate response packet. However, if RXRPC_SKB_MARK_BUSY is set, this isn't noticed and an ABORT message with a random abort code is generated (since skb->priority wasn't set to anything). Fix this by outputting the appropriate sort of packet. Also, whilst we're at it, most of the marks are no longer used, so remove them and rename the remaining two to something more obvious. Fixes: 248f219cb8bc ("rxrpc: Rewrite the data and ack handling code") Signed-off-by: David Howells <dhowells@redhat.com>
