Pull block fixes from Jens Axboe: "A collection of fixes from this series. The most important here is a regression fix for an issue that some folks would hit in blk-merge.c, and the NVMe queue depth limit for the screwed up Apple "nvme" controller. In more detail, this pull request contains: - a set of fixes for null_blk, including a fix for a few corner cases where we could hang the device. From Arianna and Paolo. - lightnvm: - A build improvement from Keith. - Update the qemu pci id detection from Matias. - Error handling fixes for leaks and other little fixes from Sudip and Wenwei. - fix from Eric where BLKRRPART would not return EBUSY for whole device mounts, only when partitions were mounted. - fix from Jan Kara, where EOF O_DIRECT reads would return negatively. - remove check for rq_mergeable() when checking limits for cloned requests. The check doesn't make any sense. It's assuming that since NOMERGE is set on the request that we don't have to recalculate limits since the request didn't change, but that's not true if the request has been redirected.

Pull tracing fix from Steven Rostedt: "During the merge window I added a new file that is used to filter trace events on pids. It filters all events where only tasks with their pid in that file exists. It also handles the sched_switch and sched_wakeup trace events where the current task does not have its pid in the file, but the task either being switched to or awaken does. Unfortunately, I forgot about sched_wakeup_new and sched_waking. Both of these tracepoints use the same class as the sched_wakeup tracepoint, and they too should be included in what gets filtered by the set_event_pid file" * tag 'trace-v4.4-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Add sched_wakeup_new and sched_waking tracepoints for pid filter

Call bnxt_cfg_rx_mode() in bnxt_init_chip() to setup uc_list and mc_list mac address filters. Before the patch, uc_list is not setup again after chip reset (such as ethtool ring size change) and macvlans don't work any more after that.

For PF, the bp->pf.mac_addr always holds the permanent MAC addr assigned by the HW. For VF, the bp->vf.mac_addr always holds the administrator assigned VF MAC addr. The random generated VF MAC addr should never get stored to bp->vf.mac_addr. This way, when the VF wants to change the MAC address, we can tell if the adminstrator has already set it and disallow the VF from changing it. v2: Fix compile error if CONFIG_BNXT_SRIOV is not set.

Jeffrey Huang authored
The existing ndo_set_mac_address only copies the new MAC addr and didn't set the new MAC addr to the HW. The correct way is to delete the existing default MAC filter from HW and add the new one. Because of RFS filters are also dependent on the default mac filter l2 context, the driver must go thru close_nic() to delete the default MAC and RFS filters, then open_nic() to set the default MAC address to HW.

If the driver is used on an ARM platform with SPARSE_IRQ defined, semantics of NR_IRQS is different (minimal value of virtual irqs) and by default it is set to 16, see arch/arm/include/asm/irq.h. This value may be less than the actual number of virtual irqs, which may break the driver initialization. The check removal allows to use the driver on such a platform, and, if irq controller driver works correctly, the check is not needed on legacy platforms.

A second problem is that qdisc_tree_decrease_qlen() calls qdisc_lookup() without proper locking : concurrent qdisc updates could corrupt the list that qdisc_match_from_root() parses to find a qdisc given its handle. Fix first problem adding a TCQ_F_NOPARENT qdisc flag that qdisc_tree_decrease_qlen() can use to abort its tree traversal, as soon as it meets a mq/mqprio qdisc children. Second problem can be fixed by RCU protection. Qdisc are already freed after RCU grace period, so qdisc_list_add() and qdisc_list_del() simply have to use appropriate rcu list variants. A future patch will add a per struct netdev_queue list anchor, so that qdisc_tree_decrease_qlen() can have more efficient lookups.

Each openvswitch tunnel vport (vxlan,gre,geneve) holds a reference to the underlying tunnel device, but never released it when such device is deleted. Deleting the underlying device via the ip tool cause the kernel to hangup in the netdev_wait_allrefs() loop. This commit ensure that on device unregistration dp_detach_port_notify() is called for all vports that hold the device reference, properly releasing it.

When a multicast group is joined on a socket, a struct ip_mc_socklist is appended to the sockets mc_list containing information about the joined group. If the interface is hot unplugged, this entry becomes stale. Prior to commit 52ad353a ("igmp: fix the problem when mc leave group") it was possible to remove the stale entry by performing a IP_DROP_MEMBERSHIP, passing either the old ifindex or ip address on the interface. However, this fix enforces that the interface must still exist. Thus with time, the number of stale entries grows, until sysctl_igmp_max_memberships is reached and then it is not possible to join and more groups. The previous patch fixes an issue where a IP_DROP_MEMBERSHIP is performed without specifying the interface, either by ifindex or ip address. However here we do supply one of these. So loosen the restriction on device existence to only apply when the interface has not been specified. This then restores the ability to clean up the stale entries.

While testing the np->opt RCU conversion, I found that UDP/IPv6 was using a mixture of xchg() and sk_dst_lock to protect concurrent changes to sk->sk_dst_cache, leading to possible corruptions and crashes. ip6_sk_dst_lookup_flow() uses sk_dst_check() anyway, so the simplest way to fix the mess is to remove sk_dst_lock completely, as we did for IPv4. __ip6_dst_store() and ip6_dst_store() share same implementation. sk_setup_caps() being called with socket lock being held or not, we have to use sk_dst_set() instead of __sk_dst_set() Note that I had to move the "np->dst_cookie = rt6_get_cookie(rt);" in ip6_dst_store() before the sk_setup_caps(sk, dst) call. This is because ip6_dst_store() can be called from process context, without any lock held. As soon as the dst is installed in sk->sk_dst_cache, dst can be freed from another cpu doing a concurrent ip6_dst_store() Doing the dst dereference before doing the install is needed to make sure no use after free would trigger.

Since Armada 38x SoC can support IP checksum for jumbo frames only on a single port, it means that this feature should be enabled per-port, rather than for the whole SoC. This patch enables setting custom TX IP checksum limit by adding new optional property to the mvneta device tree node. If not used, by default 1600B is set for "marvell,armada-370-neta" and 9800B for other strings, which ensures backward compatibility. Binding documentation is updated accordingly.

In the actual RX processing, there is same error path for both descriptor ring refilling and building skb fails. This is not correct, because after successful refill, the ring is already updated with newly allocated buffer. Then, in case of build_skb() fail, hitherto code left the original buffer unmapped.

A value originally defined in the driver was inappropriate. Even though the ingress was somehow working, writing MVNETA_RXQ_INTR_ENABLE_ALL_MASK to MVNETA_INTR_ENABLE didn't make any effect, because the bits [31:16] are reserved and read-only. This commit updates MVNETA_RXQ_INTR_ENABLE_ALL_MASK to be compliant with the controller's documentation.

This commit adds missing configuration of MBUS windows access protection in mvneta_conf_mbus_windows function - a dedicated variable for that purpose remained there unused since v3.8 initial mvneta support. Because of that the register contents were inherited from the bootloader.

Pull spi fixes from Mark Brown: "There's one fix for the core here, we weren't reinitialising the actual transferred length in messages when they get reused which meant that we'd just keep adding to the length if a message is reused. This has limited impact since it's only used in error handling cases but will really mess anything that tries to use it up when it triggers. As ever there's a small collection of driver specific fixes too" * tag 'spi-fix-v4.4-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: spi: bugfix: spi_message.transfer_length does not get reset spi: pl022: handle EPROBE_DEFER for dma spi: bcm63xx: use correct format string for printing a resource spi: mediatek: single device does not require cs_gpios spi: Add missing kerneldoc description for parameter

In the last change here, I neglected to update the cookie in one code path: when a mgmt-tx has no real cookie sent to userspace as it doesn't wait for a response, but is off-channel. The original code used the SKB pointer as the cookie and always assigned the cookie to the TX SKB in ieee80211_start_roc_work(), but my change turned this around and made the code rely on a valid cookie being passed in. Unfortunately, the off-channel no-wait TX path wasn't assigning one at all, resulting in an uninitialized stack value being used. This wasn't handed back to userspace as a cookie (since in the no-wait case there isn't a cookie), but it was tested for non-zero to distinguish between mgmt-tx and off-channel. Fix this by assigning a dummy non-zero cookie unconditionally, and get rid of a misleading comment and some dead code while at it. I'll clean up the ACK SKB handling separately later.

DFS channels should not be actively scanned as we can't be sure if we are allowed or not. If the current channel is in the DFS band, active scan might be performed after CSA, but we have no guarantee about other channels, therefore it is safer to prevent active scanning at all.

Interfaces are being initialized (setup) on addition, and torn down on removal. However, p2p device is being torn down when stopped, resulting in the next p2p start operation being done on uninitialized interface. Solve it by calling ieee80211_teardown_sdata() only on interface removal (for the non-netdev case).

Enable or disable BGX LMAC's RX/TX based on corresponding VF's status. If otherwise, when multiple LMAC's physical link is up then packets from all LMAC's whose corresponding VF is not yet initialized will get forwarded to VF0. This is due to VNIC's default configuration where CPI, RSSI e.t.c point to VF0/QSET0/RQ0. This patch will prevent multiple copies of packets on VF0.

Call netif_carrier_on() only if interface's link is up. Switching this on upon IFF_UP by default, is causing issues with ethernet channel bonding in LACP mode. Initial NETDEV_CHANGE notification was being skipped. Also fixed some issues with link/speed/duplex reporting via ethtool. Signed-off-by: Sunil Goutham <sgoutham@cavium.com> Signed-off-by: David S.
