rxrpc: Fix transmission of an abort in response to an abort
[ Upstream commit e9c0b96ec0a34fcacdf9365713578d83cecac34c ]
Under some circumstances, such as when a server socket is closing, ABORT
packets will be generated in response to incoming packets. Unfortunately,
this also may include generating aborts in response to incoming aborts -
which may cause a cycle. It appears this may be made possible by giving
the client a multicast address.
Fix this such that rxrpc_reject_packet() will refuse to generate aborts in
response to aborts.
Fixes: 248f219cb8bc ("rxrpc: Rewrite the data and ack handling code")
