Error unwinding is done incorrectly in the cited commit. When steering init fails, there is no need to perform steering cleanup. When vport error exists, error cleanup should be mirror of the setup routine, i.e. to perform steering cleanup before metadata cleanup. This avoids the call trace in accessing uninitialized objects which are skipped during steering_init() due to failure in steering_init().

Jason A.

Toke Høiland-Jørgensen authored
WireGuard currently only propagates ECN markings on tunnel decap according to the old RFC3168 specification. However, the spec has since been updated in RFC6040 to recommend slightly different decapsulation semantics. This was implemented in the kernel as a set of common helpers for ECN decapsulation, so let's just switch over WireGuard to using those, so it can benefit from this enhancement and any future tweaks. We do not drop packets with invalid ECN marking combinations, because WireGuard is frequently used to work around broken ISPs, which could be doing that.

Paolo points out that mptcp_disconnect is bogus: "lock_sock(sk); looks suspicious (lock should be already held by the caller) And call to: tcp_disconnect(sk, flags); too, sk is not a tcp socket". ->disconnect() gets called from e.g. inet_stream_connect when one tries to disassociate a connected socket again (to re-connect without closing the socket first). MPTCP however uses mptcp_stream_connect, not inet_stream_connect, for the mptcp-socket connect call. inet_stream_connect only gets called indirectly, for the tcp socket, so any ->disconnect() calls end up calling tcp_disconnect for that tcp subflow sk. This also explains why syzkaller has not yet reported a problem here. So for now replace this with a stub that doesn't do anything.

syzbot managed to set up sfq so that q->scaled_quantum was zero, triggering an infinite loop in sfq_dequeue() More generally, we must only accept quantum between 1 and 2^18 - 7, meaning scaled_quantum must be in [1, 0x7FFF] range. Otherwise, we also could have a loop in sfq_dequeue() if scaled_quantum happens to be 0x8000, since slot->allot could indefinitely switch between 0 and 0x8000.

Fix the logic that sets the enable/disable flag for the source MAC filter according to firmware spec 1.7.1. In the original firmware spec. before 1.7.1, the VF spoof check flags were not latched after making the HWRM_FUNC_CFG call, so there was a need to keep the func_flags so that subsequent calls would perserve the VF spoof check setting. A change was made in the 1.7.1 spec so that the flags became latched. So we now set or clear the anti- spoof setting directly without retrieving the old settings in the stored vf->func_flags which are no longer valid. We also remove the unneeded vf->func_flags.

In virtio_transport.c, if the virtqueue is full, the transmitting packet is queued up and it will be sent in the next iteration. This causes the same packet to be delivered multiple times to monitoring devices. We want to continue to deliver packets to monitoring devices before it is put in the virtqueue, to avoid that replies can appear in the packet capture before the transmitted packet. This patch fixes the issue, adding a new flag (tap_delivered) in struct virtio_vsock_pkt, to check if the packet is already delivered to monitoring devices. In vhost/vsock.c, we are splitting packets, so we must set 'tap_delivered' to false when we queue up the same virtio_vsock_pkt to handle the remaining bytes. Signed-off-by:
