skb->cb may contain data from previous layers. In the observed scenario, the garbage data were misinterpreted as IP6CB(skb)->frag_max_size, so that small packets sent through the tunnel are mistakenly fragmented. This patch unconditionally clears the control buffer in ip6tunnel_xmit(), which affects ip6_tunnel, ip6_udp_tunnel and ip6_gre. Currently none of these tunnels set IP6CB(skb)->flags, otherwise it needs to be done earlier. Cc: stable@vger.kernel.org Signed-off-by:

The coalesce settings behave badly when changing just one value: ... # ethtool -c eth0 rx-usecs: 249 ... # ethtool -C eth0 tx-usecs 250 ... # ethtool -c eth0 rx-usecs: 248 This occurs due to rounding errors when calculating the microseconds value - the divisons round down. This causes (eg) the rx-usecs to decrease by one every time the tx-usecs value is set as per the above. Fix this by making the divison round-to-nearest. Signed-off-by:

Abstract unix domain socket may embed null characters, these should be translated to '@' when printed out to proc the same way the null prefix is currently being translated.

Current bgmac code initializes some DMA settings in the receive control register for some hardware and then immediately clears those settings. Not clearing those settings results in ~420Mbps *improvement* in throughput; this system can now receive frames at line-rate on Broadcom 5871x hardware compared to ~520Mbps today. I also tested a few other values but found there to be no discernible difference in CPU utilization even if burst size and prefetching values are different. On the hardware tested there was no need to keep the code that cleared all but bits 16-17, but since there is a wide variety of hardware that used this driver (I did not look at all hardware docs for hardware using this IP block), I find it wise to move this call up and clear bits just after reading the default value from the hardware rather than completely removing it. This is a good candidate for -stable >=3.14 since that is when the code that was supposed to improve performance (but did not) was introduced. Signed-off-by:

Xin Long authored
Prior to this patch, in rx path, before calling lock_sock, it needed to hold assoc when got it by __sctp_lookup_association, in case other place would free/put assoc. But in __sctp_lookup_association, it lookup and hold transport, then got assoc by transport->assoc, then hold assoc and put transport. It means it didn't hold transport, yet it was returned and later on directly assigned to chunk->transport. Without the protection of sock lock, the transport may be freed/put by other places, which would cause a use-after-free issue. This patch is to fix this issue by holding transport instead of assoc. As holding transport can make sure to access assoc is also safe, and actually it looks up assoc by searching transport rhashtable, to hold transport here makes more sense. Note that the function will be renamed later on on another patch. Signed-off-by:

Prior to this patch, it used a local variable to save the transport that is looked up by __sctp_lookup_association(), and didn't return it back. But in sctp_rcv, it is used to initialize chunk->transport. So when hitting this, even if it found the transport, it was still initializing chunk->transport with null instead. This patch is to return the transport back through transport pointer that is from __sctp_rcv_lookup_harder(). Signed-off-by:

In the device, a MID entry represents a group of local ports, which can later be bound to a MDB entry. The lookup of an existing MID entry is currently done using the provided MC MAC address and VID, from the Linux bridge. However, this can result in an incorrect reuse of the same MID index in different VLAN-unaware bridges (same IP MC group and VID 0). Fix this by performing the lookup based on FID instead of VID, which is unique across different bridges. Fixes: 3a49b4fd ("mlxsw: Adding layer 2 multicast support") Signed-off-by:

When an interface is configured to use Tx/Rx-only queues, the length of the statistics would be shortened to accomodate only the statistics required per-each queue, and the values would be provided accordingly. However, the strings provided would still contain both Tx and Rx strings for each one of the queues [regardless of its configuration], which might lead to out-of-bound access when filling the buffers as well as incorrect statistics presented.

Sending zero checksum is ok for TCP, but not for UDP. UDPv6 receiver should by default drop a frame with a 0 checksum, and UDPv4 would not verify the checksum and might accept a corrupted packet. Simply replace such checksum by 0xffff, regardless of transport. This error was caught on SIT tunnels, but seems generic. Signed-off-by:

If a congestion control module doesn't provide .undo_cwnd function, tcp_undo_cwnd_reduction() will set cwnd to tp->snd_cwnd = max(tp->snd_cwnd, tp->snd_ssthresh << 1); ... which makes sense for reno (it sets ssthresh to half the current cwnd), but it makes no sense for dctcp, which sets ssthresh based on the current congestion estimate. This can cause severe growth of cwnd (eventually overflowing u32). Fix this by saving last cwnd on loss and restore cwnd based on that, similar to cubic and other algorithms.

The r8152 driver has been broken since (approx) 3.16.xx when support was added for hardware RX checksums on newer chip versions. Symptoms include random segfaults and silent data corruption over NFS. The hardware checksum logig does not work on the VER_02 dongles I have here when used with a slow embedded system CPU. Google reveals others reporting similar issues on Raspberry Pi. So, disable hardware RX checksum support for VER_02, and fix an obvious coding error for IPV6 checksums in the same function. Because this bug results in silent data corruption, it is a good candidate for back-porting to -stable >= 3.16.xx. Signed-off-by:

Driver allocates a shadow array for transmitted SKBs with X entries; That means valid indices are {0,...,X - 1}. [X == 8191] Problem is the driver also uses X as a mask for a producer/consumer in order to choose the right entry in the array which allows access to entry X which is out of bounds. To fix this, simply allocate X + 1 entries in the shadow array. Signed-off-by:

When MTU is changed from 9000 to 1500 while there is burst of inbound 9000 bytes packets, adaptor sometimes delivers 9000 bytes packets to 1500 bytes buffers. This causes memory corruption and sometimes crash. This is because of a race condition in adaptor between "RQ disable" clearing descriptor mini-cache and mini-cache valid bit being set by completion of descriptor fetch. This can result in stale RQ desc being cached and used when packets arrive. In this case, the stale descriptor have old MTU value. Solution is to write RQ->disable twice. The first write will stop any further desc fetches, allowing the second disable to clear the mini-cache valid bit without danger of a race. Also, the check for rq->running becoming 0 after writing rq->enable to 0 is not done properly. When incoming packets are flooding the interface, rq->running will pulse high for each dropped packet. Since the driver was waiting for 10us between each poll, it is possible to see rq->running = 1 1000 times in a row, even though it is not actually stuck running. This results in false failure of vnic_rq_disable(). Fix is to try more than 1000 time without delay between polls to ensure we do not miss when running goes low. In old adaptors rq->enable needs to be re-written to 0 when posted_index is reset in vnic_rq_clean() in order to keep rq->prefetch_index in sync. Signed-off-by:

In commit 2d18ac4b ("tipc: extend broadcast link initialization criteria") we tried to fix a problem with the initial synchronization of broadcast link acknowledge values. Unfortunately that solution is not sufficient to solve the issue. We have seen it happen that LINK_PROTOCOL/STATE packets with a valid non-zero unicast acknowledge number may bypass BCAST_PROTOCOL initialization, NAME_DISTRIBUTOR and other STATE packets with invalid broadcast acknowledge numbers, leading to premature opening of the broadcast link. When the bypassed packets finally arrive, they are inadvertently accepted, and the already correctly initialized acknowledge number in the broadcast receive link is overwritten by the invalid (zero) value of the said packets. After this the broadcast link goes stale. We now fix this by marking the packets where we know the acknowledge value is or may be invalid, and then ignoring the acks from those. To this purpose, we claim an unused bit in the header to indicate that the value is invalid. We set the bit to 1 in the initial BCAST_PROTOCOL synchronization packet and all initial ("bulk") NAME_DISTRIBUTOR packets, plus those LINK_PROTOCOL packets sent out before the broadcast links are fully synchronized. This minor protocol update is fully backwards compatible. Reported-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2016-10-27 This series contains fixes to ixgbe and i40e. Emil fixes a NULL pointer dereference when a macvlan interface is brought up while the PF is still down. David root caused the original panic that was fixed by commit id (a036244c "i40e: Fix kernel panic on enable/disable LLDP") and the fix was not quite correct, so removed the get_default_tc() and replaced it with a #define since there is only one TC supported as a default. Guilherme Piccoli fixes an issue where if we modprobe the driver module without enough MSI-X interrupts, then unload the module and reload it again, the kernel would crash. So if we fail to allocate enough MSI-X interrupts, we should disable them since they were previously enabled. Huaibin Wang found that the order of the arguments for ndo_dflt_bridge_getlink() were in the correct order, so fix the order. ==================== Signed-off-by:
