2017-02-18hrtimer: Catch invalid clockids againMarc Zyngier
commit 82e88ff1ea94 ("hrtimer: Revert CLOCK_MONOTONIC_RAW support") removed unfortunately a sanity check in the hrtimer code which was part of that MONOTONIC_RAW patch series. It would have caught the bogus usage of CLOCK_MONOTONIC_RAW in the wireless code. So bring it back. It is way too easy to take any random clockid and feed it to the hrtimer subsystem. At best, it gets mapped to a monotonic base, but it would be better to just catch illegal values as early as possible. Detect invalid clockids, map them to CLOCK_MONOTONIC and emit a warning.

The new HPT resizing code added in commit b5baa6877315 ("KVM: PPC: Book3S HV: KVM-HV HPT resizing implementation", 2016-12-20) doesn't have code to handle the new HPTE format which POWER9 uses. Thus it would be best not to advertise it to userspace on POWER9 systems until it works properly. Also, since resize_hpt_rehash_hpte() contains BUG_ON() calls that could be hit on POWER9, let's prevent it from being called on POWER9 for now.

2017-02-17vxlan: fix oops in dev_fill_metadata_dstPaolo Abeni
Since the commit 0c1d70af924b ("net: use dst_cache for vxlan device") vxlan_fill_metadata_dst() calls vxlan_get_route() passing a NULL dst_cache pointer, so the latter should explicitly check for valid dst_cache ptr. Unfortunately the commit d71785ffc7e7 ("net: add dst_cache to ovs vxlan lwtunnel") removed said check. As a result is possible to trigger a null pointer access calling vxlan_fill_metadata_dst(), e.g. with: ovs-vsctl add-br ovs-br0 ovs-vsctl add-port ovs-br0 vxlan0 -- set interface vxlan0 \ type=vxlan options:remote_ip=192.168.1.1 \ options:key=1234 options:dst_port=4789 ofport_request=10 ip address add dev ovs-br0 172.16.1.2/24 ovs-vsctl set Bridge ovs-br0 ipfix=@i -- --id=@i create IPFIX \ targets=\"172.16.1.1:1234\" sampling=1 iperf -c 172.16.1.1 -u -l 1000 -b 10M -t 1 -p 1234 This commit addresses the issue passing to vxlan_get_route() the dst_cache already available into the lwt info processed by vxlan_fill_metadata_dst().

2017-02-17PCI/MSI: Fix msi_desc->affinity memory leak when freeing MSI IRQsPrarit Bhargava
During device setup, msix_setup_entries() and msi_setup_entry() allocate msi_desc by calling alloc_msi_entry(). alloc_msi_entry() can also allocate a affinity cpumask. During device teardown free_msi_irqs() is called and the msi_desc is freed, but the affinity cpumask is leaked. Fix it by calling free_msi_entry() which frees both the msi_desc and the affinity cpumask. [bhelgaas: aa48b6f70886 ("genirq/MSI: Move alloc_msi_entry() from PCI into generic MSI code") moved alloc_msi_entry() from drivers/pci/msi.c to kernel/irq/msi.c and added a new corresponding free_msi_entry() interface. After aa48b6f70886, pci/msi.c used alloc_msi_entry(), but did its own kfree() instead of using free_msi_entry(). 28f4b04143c5 ("genirq/msi: Add cpumask allocation to alloc_msi_entry") added affinity to both alloc_msi_entry() and free_msi_entry(), but pci/msi.c didn't use free_msi_entry(), resulting in this leak.] Fixes: aa48b6f70886 ("genirq/MSI: Move alloc_msi_entry() from PCI into generic MSI code") Signed-off-by: Prarit Bhargava <prarit@redhat.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> CC: Myron Stowe <mstowe@redhat.com>

2017-02-17sfc: fix filter_id misinterpretation in edge caseJon Cooper
On EF10, hardware filter IDs are 13 bits, but in some places we store 32-bit "full filter IDs" in which higher order bits encode the filter match-priority. This could cause a filter to have a full filter ID of 0xffff, which is also the value EFX_EF10_FILTER_ID_INVALID which we use in 16-bit "short" filter IDs (without match-priority bits). This would occur if the hardware filter ID was 0x1fff and the match-priority was 7. Unfortunately, some code that checks for EFX_EF10_FILTER_ID_INVALID can be called on full filter IDs, and will WARN_ON if this ever happens. So, since we have plenty of spare bits in the full filter ID, this patch shifts the priority bits left one bit when constructing the full filter IDs, ensuring that the 0x2000 bit of a full filter ID will always be 0 and thus no full filter ID can ever equal EFX_EF10_FILTER_ID_INVALID. This patch also replaces open-coded full<->short filter ID conversions with calls to functions, thus keeping the definition of the full filter ID format in one place.

I don't think this driver is used much on anything other than x86, so there is no need to fix this properly and we can work around it with a Kconfig dependency to forbid known-broken configurations. qemu in theory supports it on other architectures too, but presumably only for compatibility with x86 guests that also run on vmware.

2017-02-17blk-mq-sched: ask scheduler for work, if we failed dispatching leftoversJens Axboe
Usually we don't ask the scheduler for work, if we already have leftovers on the dispatch list. This is done to leave work on the scheduler side for as long as possible, for proper merging. But if we do have work leftover but didn't dispatch anything, then we should ask the scheduler since we could potentially issue requests from that.

2017-02-17blk-mq-sched: don't add flushes to the head of requeue queueJens Axboe
If we are currently out of driver tags, we don't want to add a new flush (without a tag) to the head of the requeue list. We want to add it to the back, behind the others that are potentially also waiting for a tag. Signed-off-by: Jens Axboe <axboe@fb.com> Reviewed-by: Omar Sandoval <osandov@fb.com>

The ethtool api {get|set}_settings is deprecated. We move this driver to new api {get|set}_link_ksettings. As I don't have the hardware, I'd be very pleased if someone may test this patch. Signed-off-by: Philippe Reynes <tremyfr@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
