2013-12-31netlink: specify netlink packet direction for nlmonDaniel Borkmann2-1/+5
In order to facilitate development for netlink protocol dissector, fill the unused field skb->pkt_type of the cloned skb with a hint of the address space of the new owner (receiver) socket in the notion of "to kernel" resp. "to user". At the time we invoke __netlink_deliver_tap_skb(), we already have set the new skb owner via netlink_skb_set_owner_r(), so we can use that for netlink_is_kernel() probing. In normal PF_PACKET network traffic, this field denotes if the packet is destined for us (PACKET_HOST), if it's broadcast (PACKET_BROADCAST), etc. As we only have 3 bit reserved, we can use the value (= 6) of PACKET_FASTROUTE as it's _not used_ anywhere in the whole kernel and not supported anywhere, and packets of such type were never exposed to user space, so there are no overlapping users of such kind. Thus, as wished, that seems the only way to make both PACKET_* values non-overlapping and therefore device agnostic. By using those two flags for netlink skbs on nlmon devices, they can be made available and picked up via sll_pkttype (previously unused in netlink context) in struct sockaddr_ll. We now have these two directions: - PACKET_USER (= 6) -> to user space - PACKET_KERNEL (= 7) -> to kernel space Partial `ip a` example strace for sa_family=AF_NETLINK with detected nl msg direction: syscall: direction: sendto(3, ...) = 40 /* to kernel */ recvmsg(3, ...) = 3404 /* to user */ recvmsg(3, ...) = 1120 /* to user */ recvmsg(3, ...) = 20 /* to user */ sendto(3, ...) = 40 /* to kernel */ recvmsg(3, ...) = 168 /* to user */ recvmsg(3, ...) = 144 /* to user */ recvmsg(3, ...) = 20 /* to user */ Signed-off-by: Daniel Borkmann <dborkman@redhat.com> Signed-off-by: Jakub Zawadzki <darkjames-ws@darkjames.pl> Signed-off-by: David S.

2013-12-31netlink: only do not deliver to tap when both sides are kernel sksDaniel Borkmann1-5/+8
We should also deliver packets to nlmon devices when we are in netlink_unicast_kernel(), and only one of the {src,dst} sockets is user sk and the other one kernel sk. That's e.g. the case in netlink diag, netlink route, etc. Still, forbid to deliver messages from kernel to kernel sks.

2013-12-31Merge branch 'sctp_logspam'David S. Miller2-12/+25
Neil Horman says: ==================== sctp: Consolidate and ratelimit deprecation warnings The SCTP protocol has several deprecation warnings in its setsockopt path that can be triggered by unprivlidged users. Since these are not ratelimited, we can spam the logs quite easily here. Since these are all deprecation warnings, and that type of warning isn't uncommon in the rest of the kernel, lets make a common pr_warn_deprecated macro to produce somewhat generalized ratelimited deprecation warnings easily ==================== Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: David S.

2013-12-31SCTP: Reduce log spamming for sctp setsockoptNeil Horman1-12/+18
During a recent discussion regarding some sctp socket options, it was noted that we have several points at which we issue log warnings that can be flooded at an unbounded rate by any user. Fix this by converting all the pr_warns in the sctp_setsockopt path to be pr_warn_ratelimited. Note there are several debug level messages as well. I'm leaving those alone, as, if you turn on pr_debug, you likely want lots of verbosity.

2013-12-31tun: Add support for RFS on tun flowsTom Herbert1-2/+35
This patch adds support so that the rps_flow_tables (RFS) can be programmed using the tun flows which are already set up to track flows for the purposes of queue selection. On the receive path (corresponding to select_queue and tun_net_xmit) the rxhash is saved in the flow_entry. The original code only does flow lookup in select_queue, so this patch adds a flow lookup in tun_net_xmit if num_queues == 1 (select_queue is not called from dev_queue_xmit->netdev_pick_tx in that case). The flow is recorded (processing CPU) in tun_flow_update (TX path), and reset when flow is deleted.

2013-12-31net: Allow setting sock flow hash without a sockTom Herbert1-4/+14
This patch adds sock_rps_record_flow_hash and sock_rps_reset_flow_hash which take a hash value as an argument and sets the sock_flow_table accordingly. This allows the table to be populated in cases where flow is being tracked outside of a sock structure. sock_rps_record_flow and sock_rps_reset_flow call this function where the hash is taken from sk_rxhash.
