2016-07-13Merge branch 'sk_filter-trim-limit'David S. Miller
Willem de Bruijn says: ==================== limit sk_filter trim to payload Sockets can apply a filter to incoming packets to drop or trim them. Fix two codepaths that call skb_pull/__skb_pull after sk_filter without checking for packet length. Reading beyond skb->tail after trimming happens in more codepaths, but safety of reading in the linear segment is based on minimum allocation size (MAX_HEADER, GRO_MAX_HEAD, ..). ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2016-07-13dccp: limit sk_filter trim to payloadWillem de Bruijn
Dccp verifies packet integrity, including length, at initial rcv in dccp_invalid_packet, later pulls headers in dccp_enqueue_skb. A call to sk_filter in-between can cause __skb_pull to wrap skb->len. skb_copy_datagram_msg interprets this as a negative value, so (correctly) fails with EFAULT. The negative length is reported in ioctl SIOCINQ or possibly in a DCCP_WARN in dccp_close. Introduce an sk_receive_skb variant that caps how small a filter program can trim packets, and call this in dccp with the header length. Excessively trimmed packets are now processed normally and queued for reception as 0B payloads.

2016-07-13rose: limit sk_filter trim to payloadWillem de Bruijn
Sockets can have a filter program attached that drops or trims incoming packets based on the filter program return value. Rose requires data packets to have at least ROSE_MIN_LEN bytes. It verifies this on arrival in rose_route_frame and unconditionally pulls the bytes in rose_recvmsg. The filter can trim packets to below this value in-between, causing pull to fail, leaving the partial header at the time of skb_copy_datagram_msg. Place a lower bound on the size to which sk_filter may trim packets by introducing sk_filter_trim_cap and call this for rose packets.

2016-07-13sched/core: Correct off by one bug in load migration calculationThomas Gleixner
The move of calc_load_migrate() from CPU_DEAD to CPU_DYING did not take into account that the function is now called from a thread running on the outgoing CPU. As a result a cpu unplug leakes a load of 1 into the global load accounting mechanism. Fix it by adjusting for the currently running thread which calls calc_load_migrate().

scribble Xiaolong Ye reported lock debug warnings triggered by the following commit: 8de4a0066106 ("perf/x86: Convert the core to the hotplug state machine") The bug is the following: the cpuhp_bp_states[] array is cut short when CONFIG_SMP=n, but the dynamically registered callbacks are stored nevertheless and happily scribble outside of the array bounds... We need to store them in case that the state is unregistered so we can invoke the teardown function. That's independent of CONFIG_SMP. Make sure the array is large enough.

Florian Fainelli says: ==================== net: ethoc: Error path and transmit fixes This patch series contains two patches for the ethoc driver while testing on a TS-7300 board where ethoc is provided by an on-board FPGA. First patch was cooked after chasing crashes with invalid resources passed to the driver. Second patch was cooked after seeing that an interface configured with IP 192.168.2.2 was sending ARP packets for 192.168.0.0, no wonder why it could not work. I don't have access to any other platform using an ethoc interface so it could be good to some testing on Xtensa for instance.

In case any operation fails before we can successfully go the point where we would register a MDIO bus, we would be going to an error label which involves unregistering then freeing this yet to be created MDIO bus. Update all error paths to go to label free which is the only one valid until either the clock is enabled, or the MDIO bus is allocated and registered. This fixes kernel oops observed while trying to dereference the MDIO bus structure which is not yet allocated. Fixes: a1702857724f ("net: Add support for the OpenCores 10/100 Mbps Ethernet MAC.")

There are several computatations of the sc in the ud receive routine. Besides the code duplication, all are wrong when the sc is greater than 15. In that case the code incorrectly or's a 1 into the computed sc instead of 1 shifted left by 4. Fix precomputed sc5 by using an already implemented routine hdr2sc() and deleting flawed duplicated code.

2016-07-12netfilter: conntrack: skip clash resolution if nat is in placePablo Neira Ayuso
The clash resolution is not easy to apply if the NAT table is registered. Even if no NAT rules are installed, the nul-binding ensures that a unique tuple is used, thus, the packet that loses race gets a different source port number, as described by: http://marc.info/?l=netfilter-devel&m=146818011604484&w=2 Clash resolution with NAT is also problematic if addresses/port range ports are used since the conntrack that wins race may describe a different mangling that we may have earlier applied to the packet via nf_nat_setup_info().

2016-07-12netfilter: conntrack: protect early_drop by rcu read lockLiping Zhang
User can add ct entry via nfnetlink(IPCTNL_MSG_CT_NEW), and if the total number reach the nf_conntrack_max, we will try to drop some ct entries. But in this case(the main function call path is ctnetlink_create_conntrack -> nf_conntrack_alloc -> early_drop), rcu_read_lock is not held, so race with hash resize will happen.

2016-07-11ipv4: af_inet: make it explicitly non-modularPaul Gortmaker
The Makefile controlling compilation of this file is obj-y, meaning that it currently is never being built as a module. Since MODULE_ALIAS is a no-op for non-modular code, we can simply remove the MODULE_ALIAS_NETPROTO variant used here. We replace module.h with kmod.h since the file does make use of request_module() in order to load other modules from here. We don't have to worry about init.h coming in via the removed module.h since the file explicitly includes init.h already. Cc: "David S.

2016-07-11tipc: reset all unicast links when broadcast send link failsJon Paul Maloy
In test situations with many nodes and a heavily stressed system we have observed that the transmission broadcast link may fail due to an excessive number of retransmissions of the same packet. In such situations we need to reset all unicast links to all peers, in order to reset and re-synchronize the broadcast link. In this commit, we add a new function tipc_bearer_reset_all() to be used in such situations. The function scans across all bearers and resets all their pertaining links.

2016-07-11tipc: ensure correct broadcast send buffer release when peer is lostJon Paul Maloy
After a new receiver peer has been added to the broadcast transmission link, we allow immediate transmission of new broadcast packets, trusting that the new peer will not accept the packets until it has received the previously sent unicast broadcast initialiation message. In the same way, the sender must not accept any acknowledges until it has itself received the broadcast initialization from the peer, as well as confirmation of the reception of its own initialization message. Furthermore, when a receiver peer goes down, the sender has to produce the missing acknowledges from the lost peer locally, in order ensure correct release of the buffers that were expected to be acknowledged by the said peer. In a highly stressed system we have observed that contact with a peer may come up and be lost before the above mentioned broadcast initial- ization and confirmation have been received. This leads to the locally produced acknowledges being rejected, and the non-acknowledged buffers to linger in the broadcast link transmission queue until it fills up and the link goes into permanent congestion. In this commit, we remedy this by temporarily setting the corresponding broadcast receive link state to ESTABLISHED and the 'bc_peer_is_up' state to true before we issue the local acknowledges. This ensures that those acknowledges will always be accepted. The mentioned state values are restored immediately afterwards when the link is reset.
