| * openvswitch: packet messages need their own probe attribtueThomas Graf2015-01-141-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | User space is currently sending a OVS_FLOW_ATTR_PROBE for both flow and packet messages. This leads to an out-of-bounds access in ovs_packet_cmd_execute() because OVS_FLOW_ATTR_PROBE > OVS_PACKET_ATTR_MAX. Introduce a new OVS_PACKET_ATTR_PROBE with the same numeric value as OVS_FLOW_ATTR_PROBE to grow the range of accepted packet attributes while maintaining to be binary compatible with existing OVS binaries. Fixes: 05da589 ("openvswitch: Add support for OVS_FLOW_ATTR_PROBE.")

* | vfs: renumber FMODE_NONOTIFY and add to uniqueness checkDavid Drysdale2015-01-081-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix clashing values for O_PATH and FMODE_NONOTIFY on sparc. The clashing O_PATH value was added in commit 5229645bdc35 ("vfs: add nonconflicting values for O_PATH") but this can't be changed as it is user-visible. FMODE_NONOTIFY is only used internally in the kernel, but it is in the same numbering space as the other O_* flags, as indicated by the comment at the top of include/uapi/asm-generic/fcntl.h (and its use in fs/notify/fanotify/fanotify_user.c). So renumber it to avoid the clash. All of this has happened before (commit 12ed2e36c98a: "fanotify: FMODE_NONOTIFY and __O_SYNC in sparc conflict"), and all of this will happen again -- so update the uniqueness check in fcntl_init() to include __FMODE_NONOTIFY.

The main problem is that they most likely didn't work even before, because of a conflict in the #defines: #define KVM_SET_GUEST_DEBUG _IOW(KVMIO, 0x9b, struct kvm_guest_debug) #define KVM_IA64_VCPU_SET_STACK _IOW(KVMIO, 0x9b, void *) The argument to KVM_SET_GUEST_DEBUG is: struct kvm_guest_debug { __u32 control; __u32 pad; struct kvm_guest_debug_arch arch; }; struct kvm_guest_debug_arch { }; meaning that sizeof(struct kvm_guest_debug) == sizeof(void *) == 8 and KVM_SET_GUEST_DEBUG == KVM_IA64_VCPU_SET_STACK. KVM_SET_GUEST_DEBUG is handled in virt/kvm/kvm_main.c before even calling kvm_arch_vcpu_ioctl (which would have handled KVM_IA64_VCPU_SET_STACK), so KVM_IA64_VCPU_SET_STACK would just return -EINVAL.

Various mechanisms are responsible for correct virtio_balloon memory management. Nevertheless it is often the case that these control tools does not have enough time to react on fast changing memory load. As a result OS runs out of memory and invokes OOM-killer. The balancing of memory by use of the virtio balloon should not cause the termination of processes while there are pages in the balloon. Now there is no way for virtio balloon driver to free some memory at the last moment before some process will be get killed by OOM-killer. This does not provide a security breach as balloon itself is running inside guest OS and is working in the cooperation with the host. Thus some improvements from guest side should be considered as normal. To solve the problem, introduce a virtio_balloon callback which is expected to be called from the oom notifier call chain in out_of_memory() function. If virtio balloon could release some memory, it will make the system to return and retry the allocation that forced the out of memory killer to run. Allocate virtio feature bit for this: it is not set by default, the the guest will not deflate virtio balloon on OOM without explicit permission from host.

The interface used in procfs is ns_get_path(path, task, ops) and ns_get_name(buf, size, task, ops). Dentries and inodes are never hashed; a non-counting reference to dentry is stashed in ns_common (removed by ->d_prune()) and reused by ns_get_path() if present. See ns_get_path()/ns_prune_dentry/nsfs_evict() for details of that mechanism. As the result, proc_ns_follow_link() has stopped poking in nd->path.mnt; it does nd_jump_link() on a consistent <vfsmount,dentry> pair it gets from ns_get_path().

We continued to delete more lines than were added, always a good thing, but not at a huge rate this release, only about 70k lines removed overall mostly from removing the horrid bcm driver. Lots of normal staging driver cleanups and fixes all over the place, well over a thousand of them, the shortlog shows all the horrid details. The "contentious" thing here is the movement of the Android binder code out of staging into the "real" part of the kernel. This is code that has been stable for a few years now and is working as-is in the tens of millions of devices with no issues. Yes, the code is horrid, and the userspace api leaves a lot to be desired, but it's not going to change due to legacy issues that we have no control over. Because so many devices and companies rely on this, and the code is stable, might as well promote it out of staging. This was all discussed at the Linux Plumbers conference, and everyone participating agreed that this was the best way forward. There is work happening to replace the binder code with something new that is happening right now, but I don't expect to see the results of that work for another year at the earliest. If that ever happens, and Android switches over to it, I'll gladly remove this version. As for maintainers, I'll be glad to maintain this code, I've been doing it for the past few years with no problems. I'll send a MAINTAINERS entry for it before 3.19-final is out, still need to talk to the Google developers about if they are willing to help with it or not, last I checked they were, which was good.

This shadow buffer is not wired into the normal obj->pages and so the physical object is incoherent with accesses via the GPU, GTT and CPU. By setting up the appropriate scatter-gather table, we can allow userspace to access the physical object via either a GTT mmaping of or by rendering into the GEM bo. However, keeping the CPU mmap of the shmemfs backing storage coherent with the contiguous shadow is not yet possible. Fortuituously, CPU mmaps of objects requiring physical addresses are not expected to be coherent anyway. This allows the physical constraint of the GEM object to be transparent to userspace and allow it to efficiently render into or update them via the GTT and GPU. v2: Fix leak of pci handle spotted by Ville v3: Remove the now duplicate call to detach_phys_object during free. v4: Wait for rendering before pwrite. As this patch makes it possible to render into the phys object, we should make it correct as well!

But that's done with the two-stage approach which uses separate blob kms object and the special-purpose get_blob ioctl. Shipping userspace seems to have never relied on this, and the kernel also never put any blob thing onto that property. And nowadays it would blow up, e.g. in drm_property_destroy. Also it makes no sense to return values in an ioctl that only returns metadata about everything. So let's ditch all the internal code for the blob list, rename the list to be unambiguous and sprinkle comments all over the place to explain this peculiar piece of api. v2: Squash in fixup from Rob to remove now unused variables.
