Check for SMU RX local/remote faults along with SPU LINK status. Otherwise at times link is UP at our end but DOWN at link partner's side. Also due to an issue in BGX it's rarely seen that initialization doesn't happen properly and SMU RX reports faults with everything fine at SPU. This patch tries to reinitialize LMAC to fix it. Also fixed LMAC disable sequence to properly bring down link. Signed-off-by:

Sven Eckelmann says: ==================== batman-adv: Fixes for Linux 4.7 Antonio currently seems to be occupied. This is currently rather unfortunate because there are patches waiting in the batman-adv development repository maint(enance) branch [1] since up to 6 weeks. I am now getting asked when these patches will hit the distribution kernels and therefore decided to submit these patches directly to netdev. The patch from Simon works around the problem that warnings could be triggered in the translation table code via packets using a VLAN not configured on the target host. This warning was replaced with a rate limited info message. Ben Hutchings found an superfluous batadv_softif_vlan_put in the error handling code of the translation table while he backported the "batman-adv: Fix reference counting of vlan object for tt_local_entry" patch to the stable kernels. He noticed correctly that this batadv_softif_vlan_put should also have been removed by the said patch. The most requested fix at the moment is related to a double free in the translation table code. It is a race condition which mostly happens on systems with multiple cores and multiple network interface attached to batman-adv. Two Freifunk communities which were haunted by weird crashes (with backtraces reporting problems in other parts of the kernel) were kind enough to test this patch. They reported that there systems are now running stable after applying this patch. An invalid memory access was detected in the batadv_icmp_packet_rr handling code when receiving a skbuff with fragments. The last patch is fixing a memory leak when the interface is removed via .dellink. The code to fix it was copied from the code handling the legacy sysfs interface to remove netdevices from a batman-adv netdevice. There are still 28 patches in the development tree for v4.8 but I will leave them to Antonio because these are cleanups and features and therefore for net- next. ==================== Signed-off-by:

The tt_req_node is added and removed from a list inside a spinlock. But the locking is sometimes removed even when the object is still referenced and will be used later via this reference. For example batadv_send_tt_request can create a new tt_req_node (including add to a list) and later re-acquires the lock to remove it from the list and to free it. But at this time another context could have already removed this tt_req_node from the list and freed it.

Simon Wunderlich authored
If a VLAN tagged frame is received and the corresponding VLAN is not configured on the soft interface, it will splat a WARN on every packet received. This is a quite annoying behaviour for some scenarios, e.g. if bat0 is bridged with eth0, and there are arbitrary VLAN tagged frames from Ethernet coming in without having any VLAN configuration on bat0. The code should probably create vlan objects on the fly and transparently transport these VLAN-tagged Ethernet frames, but until this is done, at least the WARN splat should be replaced by a rate limited output.

If we have a system which uses fixed PHY devices and calls fixed_phy_register() then fixed_phy_unregister() we can exhaust the number of fixed PHYs available after a while, since we keep incrementing the variable phy_fixed_addr, but we never decrement it.

The proc connector messages include a sequence number, allowing userspace programs to detect lost messages. However, performing this detection is currently more difficult than necessary, since netlink messages can be delivered to the application out-of-order. To fix this, leave pre-emption disabled during cn_netlink_send(), and use GFP_NOWAIT. The following was written as a test case. Building the kernel w/ make -j32 proved a reliable way to generate out-of-order cn_proc messages. int main(int argc, char *argv[]) { static uint32_t last_seq[CPU_SETSIZE], seq; int cpu, fd; struct sockaddr_nl sa; struct __attribute__((aligned(NLMSG_ALIGNTO))) { struct nlmsghdr nl_hdr; struct __attribute__((__packed__)) { struct cn_msg cn_msg; struct proc_event cn_proc; }; } rmsg; struct __attribute__((aligned(NLMSG_ALIGNTO))) { struct nlmsghdr nl_hdr; struct __attribute__((__packed__)) { struct cn_msg cn_msg; enum proc_cn_mcast_op cn_mcast; }; } smsg; fd = socket(PF_NETLINK, SOCK_DGRAM, NETLINK_CONNECTOR); if (fd < 0) { perror("socket"); } sa.nl_family = AF_NETLINK; sa.nl_groups = CN_IDX_PROC; sa.nl_pid = getpid(); if (bind(fd, (struct sockaddr *)&sa, sizeof(sa)) < 0) { perror("bind"); } memset(&smsg, 0, sizeof(smsg)); smsg.nl_hdr.nlmsg_len = sizeof(smsg); smsg.nl_hdr.nlmsg_pid = getpid(); smsg.nl_hdr.nlmsg_type = NLMSG_DONE; smsg.cn_msg.id.idx = CN_IDX_PROC; smsg.cn_msg.id.val = CN_VAL_PROC; smsg.cn_msg.len = sizeof(enum proc_cn_mcast_op); smsg.cn_mcast = PROC_CN_MCAST_LISTEN; if (send(fd, &smsg, sizeof(smsg), 0) != sizeof(smsg)) { perror("send"); } while (recv(fd, &rmsg, sizeof(rmsg), 0) == sizeof(rmsg)) { cpu = rmsg.cn_proc.cpu; if (cpu < 0) { continue; } seq = rmsg.cn_msg.seq; if ((last_seq[cpu] != 0) && (seq != last_seq[cpu] + 1)) { printf("out-of-order seq=%d on cpu=%d\n", seq, cpu); } last_seq[cpu] = seq; } /* NOTREACHED */ perror("recv"); return -1; } Signed-off-by:

The bridge is falsly dropping ipv6 mulitcast packets if there is: 1. No ipv6 address assigned on the brigde. 2. No external mld querier present. 3. The internal querier enabled. When the bridge fails to build mld queries, because it has no ipv6 address, it slilently returns, but keeps the local querier enabled. This specific case causes confusing packet loss. Ipv6 multicast snooping can only work if: a) An external querier is present OR b) The bridge has an ipv6 address an is capable of sending own queries Otherwise it has to forward/flood the ipv6 multicast traffic, because snooping cannot work. This patch fixes the issue by adding a flag to the bridge struct that indicates that there is currently no ipv6 address assinged to the bridge and returns a false state for the local querier in __br_multicast_querier_exists().

Since commit 7bb11dc9 ("bonding: unify all places where actor-oper key needs to be updated."), the logic in bonding to handle selection between multiple aggregators has not functioned. This affects only configurations wherein the bonding slaves connect to two discrete aggregators (e.g., two independent switches, each with LACP enabled), thus creating two separate aggregation groups within a single bond. The cause is a change in 7bb11dc9 to no longer set AD_PORT_BEGIN on a port after a link state change, which would cause the port to be reselected for attachment to an aggregator as if were newly added to the bond. We cannot restore the prior behavior, as it contradicts IEEE 802.1AX 5.4.12, which requires ports that "become inoperable" (lose carrier, setting port_enabled=false as per 802.1AX 5.4.7) to remain selected (i.e., assigned to the aggregator). As the port now remains selected, the aggregator selection logic is not invoked. A side effect of this change is that aggregators in bonding will now contain ports that are link down. The aggregator selection logic does not currently handle this situation correctly, causing incorrect aggregator selection. This patch makes two changes to repair the aggregator selection logic in bonding to function as documented and within the confines of the standard: First, the aggregator selection and related logic now utilizes the number of active ports per aggregator, not the number of selected ports (as some selected ports may be down). The ad_select "bandwidth" and "count" options only consider ports that are link up. Second, on any carrier state change of any slave, the aggregator selection logic is explicitly called to insure the correct aggregator is active. Reported-by:

with the commit 8c14586f ("net: ipv6: Use passed in table for nexthop lookups"), net hop lookup is first performed on route creation in the passed-in table.

Alexey reported that we have GFP_KERNEL allocation when holding the spinlock tcf_lock. Actually we don't have to take that spinlock for all the cases, especially for the new one we just create. To modify the existing actions, we still need this spinlock to make sure the whole update is atomic. For net-next, we can get rid of this spinlock because we already hold the RTNL lock on slow path, and on fast path we can use RCU to protect the metalist. Joint work with Jamal. Reported-by:
