2017-01-18can: c_can_pci: fix null-pointer-deref in c_can_start() - set device pointerEinar Jón
The priv->device pointer for c_can_pci is never set, but it is used without a NULL check in c_can_start(). Setting it in c_can_pci_probe() like c_can_plat_probe() prevents c_can_pci.ko from crashing, with and without CONFIG_PM. This might also cause the pm_runtime_*() functions in c_can.c to actually be executed for c_can_pci devices - they are the only other place where priv->device is used, but they all contain a null check.

2017-01-17bpf: Fix test_lru_sanity5() in test_lru_map.cMartin KaFai Lau
test_lru_sanity5() fails when the number of online cpus is fewer than the number of possible cpus. It can be reproduced with qemu by using cmd args "--smp cpus=2,maxcpus=8". The problem is the loop in test_lru_sanity5() is testing 'i' which is incorrect. This patch: 1. Make sched_next_online() always return -1 if it cannot find a next cpu to schedule the process. 2. In test_lru_sanity5(), the parent process does sched_setaffinity() first (through sched_next_online()) and the forked process will inherit it according to the 'man sched_setaffinity'.

2017-01-17stmmac: add missing of_node_putJulia Lawall
The function stmmac_dt_phy provides several possibilities for initializing plat->mdio_node, all of which have the effect of increasing the reference count of the assigned value. This field is not updated elsewhere, so the value is live until the end of the lifetime of plat (devm_allocated), just after the end of stmmac_remove_config_dt. Thus, add an of_node_put on plat->mdio_node in stmmac_remove_config_dt. It is possible that the field mdio_node is never initialized, but of_node_put is NULL-safe, so it is also safe to call of_node_put in that case.

This patch part reverts fd2a0437dc33 and e858fae2b0b8 which introduced a subtle change in how the virtio_net flags are derived from the SKBs ip_summed field. With the above commits, the flags are set to VIRTIO_NET_HDR_F_DATA_VALID when ip_summed == CHECKSUM_UNNECESSARY, thus treating it differently to ip_summed == CHECKSUM_NONE, which should be the same. Further, the virtio spec 1.0 / CS04 explicitly says that VIRTIO_NET_HDR_F_DATA_VALID must not be set by the driver.

transitions Save the qp context flags byte containing the flag disabling vlan stripping in the RESET to INIT qp transition, rather than in the INIT to RTR transition. Per the firmware spec, the flags in this byte are active in the RESET to INIT transition. As a result of saving the flags in the incorrect qp transition, when switching dynamically from VGT to VST and back to VGT, the vlan remained stripped (as is required for VST) and did not return to not-stripped (as is required for VGT).

2017-01-16net/mlx4_core: Fix racy CQ (Completion Queue) freeJack Morgenstein
In function mlx4_cq_completion() and mlx4_cq_event(), the radix_tree_lookup requires a rcu_read_lock. This is mandatory: if another core frees the CQ, it could run the radix_tree_node_rcu_free() call_rcu() callback while its being used by the radix tree lookup function. Additionally, in function mlx4_cq_event(), since we are adding the rcu lock around the radix-tree lookup, we no longer need to take the spinlock. Also, the synchronize_irq() call for the async event eliminates the need for incrementing the cq reference count in mlx4_cq_event(). Other changes: 1. In function mlx4_cq_free(), replace spin_lock_irq with spin_lock: we no longer take this spinlock in the interrupt context. The spinlock here, therefore, simply protects against different threads simultaneously invoking mlx4_cq_free() for different cq's. 2. In function mlx4_cq_free(), we move the radix tree delete to before the synchronize_irq() calls. This guarantees that we will not access this cq during any subsequent interrupts, and therefore can safely free the CQ after the synchronize_irq calls. The rcu_read_lock in the interrupt handlers only needs to protect against corrupting the radix tree; the interrupt handlers may access the cq outside the rcu_read_lock due to the synchronize_irq calls which protect against premature freeing of the cq. 3. In function mlx4_cq_event(), we change the mlx_warn message to mlx4_dbg. 4. We leave the cq reference count mechanism in place, because it is still needed for the cq completion tasklet mechanism.

The problem being gcc cannot tell that if(IS_ERR()) in mlx5e_route_lookup_ipv4() is equivalent to checking if(err) later, so it assumes that 'out_dev' is used after the 'return PTR_ERR(rt)'. The PTR_ERR_OR_ZERO() case by comparison is fairly easy to detect by gcc, so it can't get that wrong, so it no longer warns. Hadar Hen Zion already attempted to fix the warning earlier by adding fake initializations, but that ended up not fully addressing all warnings, so I'm reverting it now that it is no longer needed.

2017-01-16bpf: rework prog_digest into prog_tagDaniel Borkmann
Commit 7bd509e311f4 ("bpf: add prog_digest and expose it via fdinfo/netlink") was recently discussed, partially due to admittedly suboptimal name of "prog_digest" in combination with sha1 hash usage, thus inevitably and rightfully concerns about its security in terms of collision resistance were raised with regards to use-cases. The intended use cases are for debugging resp. introspection only for providing a stable "tag" over the instruction sequence that both kernel and user space can calculate independently. It's not usable at all for making a security relevant decision. So collisions where two different instruction sequences generate the same tag can happen, but ideally at a rather low rate. The "tag" will be dumped in hex and is short enough to introspect in tracepoints or kallsyms output along with other data such as stack trace, etc. Thus, this patch performs a rename into prog_tag and truncates the tag to a short output (64 bits) to make it obvious it's not collision-free. Should in future a hash or facility be needed with a security relevant focus, then we can think about requirements, constraints, etc that would fit to that situation. For now, rework the exposed parts for the current use cases as long as nothing has been released yet. Tested on x86_64 and s390x.

2017-01-16ip6_tunnel: Account for tunnel header in tunnel MTUJakub Sitnicki
With ip6gre we have a tunnel header which also makes the tunnel MTU smaller. We need to reserve room for it. Previously we were using up space reserved for the Tunnel Encapsulation Limit option header (RFC 2473). Also, after commit b05229f44228 ("gre6: Cleanup GREv6 transmit path, call common GRE functions") our contract with the caller has changed. Now we check if the packet length exceeds the tunnel MTU after the tunnel header has been pushed, unlike before. This is reflected in the check where we look at the packet length minus the size of the tunnel header, which is already accounted for in tunnel MTU.

2017-01-16mld: do not remove mld souce list info when set link downHangbin Liu
This is an IPv6 version of commit 24803f38a5c0 ("igmp: do not remove igmp souce list..."). In mld_del_delrec(), we will restore back all source filter info instead of flush them. Move mld_clear_delrec() from ipv6_mc_down() to ipv6_mc_destroy_dev() since we should not remove source list info when set link down. Remove igmp6_group_dropped() in ipv6_mc_destroy_dev() since we have called it in ipv6_mc_down(). Also clear all source info after igmp6_group_dropped() instead of in it because ipv6_mc_down() will call igmp6_group_dropped().

2017-01-16be2net: fix MAC addr setting on privileged BE3 VFsIvan Vecera
During interface opening MAC address stored in netdev->dev_addr is programmed in the HW with exception of BE3 VFs where the initial MAC is programmed by parent PF. This is OK when MAC address is not changed when an interfaces is down. In this case the requested MAC is stored to netdev->dev_addr and later is stored into HW during opening. But this is not done for all BE3 VFs so the NIC HW does not know anything about this change and all traffic is filtered. This is the case of bonding if fail_over_mac == 0 where the MACs of the slaves are changed while they are down. The be2net behavior is too restrictive because if a BE3 VF has the FILTMGMT privilege then it is able to modify its MAC without any restriction. To solve the described problem the driver should take care about these privileged BE3 VFs so the MAC is programmed during opening. And by contrast unpriviled BE3 VFs should not be allowed to change its MAC in any case.

2017-01-16cpmac: remove hopeless #warningArnd Bergmann
The #warning was present 10 years ago when the driver first got merged. As the platform is rather obsolete by now, it seems very unlikely that the warning will cause anyone to fix the code properly. kernelci.org reports the warning for every build in the meantime, so I think it's better to just turn it into a code comment to reduce noise.

2017-01-16ravb: do not use zero-length alignment DMA descriptorMasaru Nagai
Due to alignment requirements of the hardware transmissions are split into two DMA descriptors, a small padding descriptor of 0 - 3 bytes in length followed by a descriptor for rest of the packet. In the case of IP packets the first descriptor will never be zero due to the way that the stack aligns buffers for IP packets. However, for non-IP packets it may be zero. In that case it has been reported that timeouts occur, presumably because transmission stops at the first zero-length DMA descriptor and thus the packet is not transmitted. However, in my environment a BUG is triggered as follows: [ 20.381417] ------------[ cut here ]------------ [ 20.386054] kernel BUG at lib/swiotlb.c:495!

2017-01-16mmc: core: Restore parts of the polling policy when switch to HS/HS DDRUlf Hansson
Regressions for not being able to detect an eMMC HS DDR mode card has been reported for the sdhci-esdhc-imx driver, but potentially other sdhci variants may suffer from the similar problem. The commit e173f8911f09 ("mmc: core: Update CMD13 polling policy when switch to HS DDR mode"), is causing the problem. It seems that change moved one step to far, regarding changing the host's timing before polling for a busy card. To fix this, let's move back to the behaviour when the host's timing is updated after the polling, but before the switch status is fetched and validated. In cases when polling with CMD13, we keep validating the switch status at each attempt. However, to align with the other card busy detections mechanism, let's fetch and validate the switch status also after the host's timing is updated.
