Jiri Pirko says: ==================== mlxsw: spectrum: Configure TTL of "inherit" for offloaded tunnels Petr says: Currently mlxsw only offloads tunnels that are configured with TTL of "inherit" (which is the default). However, Spectrum defaults to 255 and the driver neglects to change the configuration. Thus the tunnel packets from offloaded tunnels always have TTL of 255, even though tunnels with explicit TTL of 255 are never actually offloaded. To fix this, introduce support for TIGCR, the register that keeps the related bits of global tunnel configuration, and use it on first offload to properly configure inheritance of TTL of tunnel packets from overlay packets. ==================== Signed-off-by: David S.

2017-10-22net: ethtool: remove error check for legacy setting transceiver typeNiklas Söderlund
Commit 9cab88726929605 ("net: ethtool: Add back transceiver type") restores the transceiver type to struct ethtool_link_settings and convert_link_ksettings_to_legacy_settings() but forgets to remove the error check for the same in convert_legacy_settings_to_link_ksettings(). This prevents older versions of ethtool to change link settings. # ethtool --version ethtool version 3.16 # ethtool -s eth0 autoneg on speed 100 duplex full Cannot set new settings: Invalid argument not setting speed not setting duplex not setting autoneg While newer versions of ethtool works. # ethtool --version ethtool version 4.10 # ethtool -s eth0 autoneg on speed 100 duplex full [ 57.703268] sh-eth ee700000.ethernet eth0: Link is Down [ 59.618227] sh-eth ee700000.ethernet eth0: Link is Up - 100Mbps/Full - flow control rx/tx Fixes: 19cab88726929605 ("net: ethtool: Add back transceiver type") Signed-off-by: Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se> Reported-by: Renjith R V <renjith.rv@quest-global.com> Tested-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: David S.

The existing implementation assumedthat the socket lock protected both of these paths when it actually only protects the SO_ATTACH_REUSEPORT path. Syzkaller triggered this double allocation by running these paths concurrently. This patch moves the check for double allocation into the reuseport_alloc function which is protected by a global spin lock.

2017-10-22sock: correct sk_wmem_queued accounting on efault in tcp zerocopyWillem de Bruijn
Syzkaller hits WARN_ON(sk->sk_wmem_queued) in sk_stream_kill_queues after triggering an EFAULT in __zerocopy_sg_from_iter. On this error, skb_zerocopy_stream_iter resets the skb to its state before the operation with __pskb_trim. It cannot kfree_skb like datagram callers, as the skb may have data from a previous send call. __pskb_trim calls skb_condense for unowned skbs, which adjusts their truesize. These tcp skbuffs are owned and their truesize must add up to sk_wmem_queued. But they match because their skb->sk is NULL until tcp_transmit_skb. Temporarily set skb->sk when calling __pskb_trim to signal that the skbuffs are owned and avoid the skb_condense path.

2017-10-22bpf: fix pattern matches for direct packet accessDaniel Borkmann
Alexander had a test program with direct packet access, where the access test was in the form of data + X > data_end. In an unrelated change to the program LLVM decided to swap the branches and emitted code for the test in form of data + X <= data_end. We hadn't seen these being generated previously, thus verifier would reject the program. Therefore, fix up the verifier to detect all test cases, so we don't run into such issues in the future.

2017-10-22bpf: fix off by one for range markings with L{T, E} patternsDaniel Borkmann
During review I noticed that the current logic for direct packet access marking in check_cond_jmp_op() has an off by one for the upper right range border when marking in find_good_pkt_pointers() with BPF_JLT and BPF_JLE. It's not really harmful given access up to pkt_end is always safe, but we should nevertheless correct the range marking before it becomes ABI. If pkt_data' denotes a pkt_data derived pointer (pkt_data + X), then for pkt_data' < pkt_end in the true branch as well as for pkt_end <= pkt_data' in the false branch we mark the range with X although it should really be X - 1 in these cases. For example, X could be pkt_end - pkt_data, then when testing for pkt_data' < pkt_end the verifier simulation cannot deduce that a byte load of pkt_data' - 1 would succeed in this branch.

2017-10-21hwmon: (da9052) Increase sample rate when using TSIMartyn Welch
The TSI channel, which is usually used for touchscreen support, but can be used as 4 general purpose ADCs. When used as a touchscreen interface the touchscreen driver switches the device into 1ms sampling mode (rather than the default 10ms economy mode) as recommended by the manufacturer. When using the TSI channels as a general purpose ADC we are currently not doing this and testing suggests that this can result in ADC timeouts: [ 5827.198289] da9052 spi2.0: timeout waiting for ADC conversion interrupt [ 5827.728293] da9052 spi2.0: timeout waiting for ADC conversion interrupt [ 5993.808335] da9052 spi2.0: timeout waiting for ADC conversion interrupt [ 5994.328441] da9052 spi2.0: timeout waiting for ADC conversion interrupt [ 5994.848291] da9052 spi2.0: timeout waiting for ADC conversion interrupt Switching to the 1ms timing resolves this issue.

2017-10-21arm/arm64: KVM: set right LR register value for 32 bit guest when inject abortDongjiu Geng
When a exception is trapped to EL2, hardware uses ELR_ELx to hold the current fault instruction address. If KVM wants to inject a abort to 32 bit guest, it needs to set the LR register for the guest to emulate this abort happened in the guest. Because ARM32 architecture is pipelined execution, so the LR value has an offset to the fault instruction address. The offsets applied to Link value for exceptions as shown below, which should be added for the ARM32 link register(LR).

2017-10-21cpu/hotplug: Reset node state after operationThomas Gleixner
The recent rework of the cpu hotplug internals changed the usage of the per cpu state->node field, but missed to clean it up after usage. So subsequent hotplug operations use the stale pointer from a previous operation and hand it into the callback functions. The callbacks then dereference a pointer which either belongs to a different facility or points to freed and potentially reused memory. In either case data corruption and crashes are the obvious consequence. Reset the node and the last pointers in the per cpu state to NULL after the operation which set them has completed.

2017-10-21udp: make some messages more descriptiveMatteo Croce
In the UDP code there are two leftover error messages with very few meaning. Replace them with a more descriptive error message as some users reported them as "strange network error". Signed-off-by: Matteo Croce <mcroce@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-10-21geneve: Fix function matching VNI and tunnel ID on big-endianStefano Brivio
On big-endian machines, functions converting between tunnel ID and VNI use the three LSBs of tunnel ID storage to map VNI. The comparison function eq_tun_id_and_vni(), on the other hand, attempted to map the VNI from the three MSBs. Fix it by using the same check implemented on LE, which maps VNI from the three LSBs of tunnel ID. Fixes: 2e0b26e10352 ("geneve: Optimize geneve device lookup.")
