2017-05-16dm bufio: make the parameter "retain_bytes" unsigned longMikulas Patocka1-8/+8
Change the type of the parameter "retain_bytes" from unsigned to unsigned long, so that on 64-bit machines the user can set more than 4GiB of data to be retained. Also, change the type of the variable "count" in the function "__evict_old_buffers" to unsigned long. The assignment "count = c->n_buffers[LIST_CLEAN] + c->n_buffers[LIST_DIRTY];" could result in unsigned long to unsigned overflow and that could result in buffers not being freed when they should. While at it, avoid division in get_retain_buffers(). Division is slow, we can change it to shift because we have precalculated the log2 of block size.

2017-05-16net: Improve handling of failures on link and route dumpsDavid Ahern3-28/+49
In general, rtnetlink dumps do not anticipate failure to dump a single object (e.g., link or route) on a single pass. As both route and link objects have grown via more attributes, that is no longer a given. netlink dumps can handle a failure if the dump function returns an error; specifically, netlink_dump adds the return code to the response if it is <= 0 so userspace is notified of the failure. The missing piece is the rtnetlink dump functions returning the error. Fix route and link dump functions to return the errors if no object is added to an skb (detected by skb->len != 0). IPv6 route dumps (rt6_dump_route) already return the error; this patch updates IPv4 and link dumps. Other dump functions may need to be ajusted as well.

2017-05-16smc: switch to usage of IB_PD_UNSAFE_GLOBAL_RKEYUrsula Braun5-37/+8
Currently, SMC enables remote access to physical memory when a user has successfully configured and established an SMC-connection until ten minutes after the last SMC connection is closed. Because this is considered a security risk, drivers are supposed to use IB_PD_UNSAFE_GLOBAL_RKEY in such a case. This patch changes the current SMC code to use IB_PD_UNSAFE_GLOBAL_RKEY. This improves user awareness, but does not remove the security risk itself. Signed-off-by: Ursula Braun <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2017-05-16tcp: eliminate negative reordering in tcp_clean_rtx_queueSoheil Hassas Yeganeh1-1/+1
tcp_ack() can call tcp_fragment() which may dededuct the value tp->fackets_out when MSS changes. When prior_fackets is larger than tp->fackets_out, tcp_clean_rtx_queue() can invoke tcp_update_reordering() with negative values. This results in absurd tp->reodering values higher than sysctl_tcp_max_reordering. Note that tcp_update_reordering indeeds sets tp->reordering to min(sysctl_tcp_max_reordering, metric), but because the comparison is signed, a negative metric always wins.

2017-05-16usb: dwc3: gadget: Prevent losing events in event cacheThinh Nguyen1-0/+9
The dwc3 driver can overwite its previous events if its top-half IRQ handler (TH) gets invoked again before processing the events in the cache. We see this as a hang in the file transfer and the host will attempt to reset the device. TH gets the event count and deasserts the interrupt line by writing DWC3_GEVNTSIZ_INTMASK to DWC3_GEVNTSIZ. If there's a new event coming between reading the event count and interrupt deassertion, dwc3 will lose previous pending events. More generally, we will see 0 event count, which should not affect anything. This shouldn't be possible in the current dwc3 implementation. However, through testing and reading the PCIe trace, the TH occasionally still gets invoked one more time after HW interrupt deassertion. (With PCIe legacy interrupts, TH is called repeatedly as long as the interrupt line is asserted). We suspect that there is a small detection delay in the SW. To avoid this issue, Check DWC3_EVENT_PENDING flag to determine if the events are processed in the bottom-half IRQ handler. If not, return IRQ_HANDLED and don't process new event.

2017-05-16kvm: arm/arm64: Fix use after free of stage2 page tableSuzuki K Poulose1-4/+13
We yield the kvm->mmu_lock occassionaly while performing an operation (e.g, unmap or permission changes) on a large area of stage2 mappings. However this could possibly cause another thread to clear and free up the stage2 page tables while we were waiting for regaining the lock and thus the original thread could end up in accessing memory that was freed. This patch fixes the problem by making sure that the stage2 pagetable is still valid after we regain the lock. The fact that mmu_notifer->release() could be called twice (via __mmu_notifier_release and mmu_notifier_unregsister) enhances the possibility of hitting this race where there are two threads trying to unmap the entire guest shadow pages. While at it, cleanup the redudant checks around cond_resched_lock in stage2_wp_range(), as cond_resched_lock already does the same checks.

2017-05-15ldmvsw: unregistering netdev before disable hardwareThomas Tai1-1/+1
When running LDom binding/unbinding test, kernel may panic in ldmvsw_open(). It is more likely that because we're removing the ldc connection before unregistering the netdev in vsw_port_remove(), we set up a window of time where one process could be removing the device while another trying to UP the device. This also sometimes causes vio handshake error due to opening a device without closing it completely. We should unregister the netdev before we disable the "hardware".

2017-05-15dm mpath: multipath_clone_and_map must not return -EIOChristoph Hellwig1-1/+1
Since 412445ac ("dm: introduce a new DM_MAPIO_KILL return value"), the clone_and_map_rq methods must not return errno values, so fix it up to properly return DM_MAPIO_KILL, instead of the -EIO value that snuck in due to a conflict between two patches.

2017-05-15ipv6: avoid dad-failures for addresses with NODADMahesh Bandewar1-1/+4
Every address gets added with TENTATIVE flag even for the addresses with IFA_F_NODAD flag and dad-work is scheduled for them. During this DAD process we realize it's an address with NODAD and complete the process without sending any probe. However the TENTATIVE flags stays on the address for sometime enough to cause misinterpretation when we receive a NS. While processing NS, if the address has TENTATIVE flag, we mark it DADFAILED and endup with an address that was originally configured as NODAD with DADFAILED. We can't avoid scheduling dad_work for addresses with NODAD but we can avoid adding TENTATIVE flag to avoid this racy situation.

Device node iterators put the previous value of the index variable, so an explicit put causes a double put. In particular, of_mdiobus_register can fail before doing anything interesting, so one could view it as a no-op from the reference count point of view.

2017-05-15macvlan: Fix performance issues with vlan tagged packetsVlad Yasevich1-2/+5
Macvlan always turns on offload features that have sofware fallback (NETIF_GSO_SOFTWARE). This allows much higher guest-guest communications over macvtap. However, macvtap does not turn on these features for vlan tagged traffic. As a result, depending on the HW that mactap is configured on, the performance of guest-guest communication over a vlan is very inconsistent. If the HW supports TSO/UFO over vlans, then the performance will be fine. If not, the the performance will suffer greatly since the VM may continue using TSO/UFO, and will force the host segment the traffic and possibly overlow the macvtap queue. This patch adds the always on offloads to vlan_features. This makes sure that any vlan tagged traffic between 2 guest will not be segmented needlessly.
