parentrxrpc: Improve jumbo packet counting (diff)
rxrpc: Use info in skbuff instead of reparsing a jumbo packet
Use the information now cached in the skbuff private data to avoid the need to reparse a jumbo packet. We can find all the subpackets by dead reckoning, so it's only necessary to note how many there are, whether the last one is flagged as LAST_PACKET and whether any have the REQUEST_ACK flag set. This is necessary as once recvmsg() can see the packet, it can start modifying it, such as doing in-place decryption. Fixes: 248f219cb8bc ("rxrpc: Rewrite the data and ack handling code") Signed-off-by: David Howells <dhowells@redhat.com>
