The match 00:xx:00:00:xx:00:00:00:00:xx:xx:xx (where xx indicates "don't care") should be represented by a pattern of twelve zero bytes, and a mask of "0xed,0x01", not "0xed,0x07". mask_len = (pat_len + 7) / 8 = (12 + 7) / 8 = 2 Hence the mask will be of 2 bytes. Replace each valid byte in pattern by 1 and don't care byte by 0: 10110111 1000 (0000) 1st byte of pattern corresponds to lower order bit in first byte of mask. And 9th byte of pattern corresponds to lower order bit in second byte of mask.

2013-02-11KVM: ARM: Introduce KVM_ARM_SET_DEVICE_ADDR ioctlChristoffer Dall1-0/+8
On ARM some bits are specific to the model being emulated for the guest and user space needs a way to tell the kernel about those bits. An example is mmio device base addresses, where KVM must know the base address for a given device to properly emulate mmio accesses within a certain address range or directly map a device with virtualiation extensions into the guest address space. We make this API ARM-specific as we haven't yet reached a consensus for a generic API for all KVM architectures that will allow us to do something like this.

2013-02-10VSOCK: Introduce VM SocketsAndy King1-0/+171
VM Sockets allows communication between virtual machines and the hypervisor. User level applications both in a virtual machine and on the host can use the VM Sockets API, which facilitates fast and efficient communication between guest virtual machines and their host. A socket address family, designed to be compatible with UDP and TCP at the interface level, is provided. Today, VM Sockets is used by various VMware Tools components inside the guest for zero-config, network-less access to VMware host services. In addition to this, VMware's users are using VM Sockets for various applications, where network access of the virtual machine is restricted or non-existent. Examples of this are VMs communicating with device proxies for proprietary hardware running as host applications and automated testing of applications running within virtual machines. The VMware VM Sockets are similar to other socket types, like Berkeley UNIX socket interface. The VM Sockets module supports both connection-oriented stream sockets like TCP, and connectionless datagram sockets like UDP. The VM Sockets protocol family is defined as "AF_VSOCK" and the socket operations split for SOCK_DGRAM and SOCK_STREAM. For additional information about the use of VM Sockets, please refer to the VM Sockets Programming Guide available at: https://www.vmware.com/support/developer/vmci-sdk/ Signed-off-by: George Zhang <[email protected]> Signed-off-by: Dmitry Torokhov <[email protected]> Signed-off-by: Andy king <[email protected]> Signed-off-by: David S.

2013-02-08unbreak automounter support on 64-bit kernel with 32-bit userspace (v2)Helge Deller1-17/+8
automount-support is broken on the parisc architecture, because the existing #if list does not include a check for defined(__hppa__). The HPPA (parisc) architecture is similiar to other 64bit Linux targets where we have to define autofs_wqt_t (which is passed back and forth to user space) as int type which has a size of 32bit across 32 and 64bit kernels. During the discussion on the mailing list, H. Peter Anvin suggested to invert the #if list since only specific platforms (specifically those who do not have a 32bit userspace, like IA64 and Alpha) should have autofs_wqt_t as unsigned long type. This suggestion is probably the best way to go, since Arm64 (and maybe others?) seems to have a non-working automounter. So in the long run even for other new upcoming architectures this inverted check seem to be the best solution, since it will not require them to change this #if again (unless they are 64bit only).

In per-station statistics, present 32bit counters are too small for practical purposes - with gigabit speeds, it get overlapped every few seconds. Expand counters in the struct station_info to be 64-bit. Driver can still fill only 32-bit and indicate in @filled only bits like STATION_INFO_[TR]X_BYTES; in case driver provides full 64-bit counter, it should also set in @filled bit STATION_INFO_[TR]RX_BYTES64 Netlink sends both 32-bit and 64-bit counters, if present, to not break userspace.

2013-01-31wanrouter: delete now orphaned header content, files/driversPaul Gortmaker1-439/+4
The wanrouter support was identified earlier as unused for years, and so the previous commit totally decoupled it from the kernel, leaving the related wanrouter files present, but totally inert. Here we take the final step in that cleanup, by doing a wholesale removal of these files. The two step process is used so that the large deletion is decoupled from the git history of files that we still care about. The drivers deleted here all were dependent on the Kconfig setting CONFIG_WAN_ROUTER_DRIVERS. A stub wanrouter.h header (kernel & uapi) are left behind so that drivers/isdn/i4l/isdn_x25iface.c continues to compile, and so that we don't accidentally break userspace that expected these defines.

2013-01-24fuse: implement NFS-like readdirplus supportAnand V. Avati1-0/+12
This patch implements readdirplus support in FUSE, similar to NFS. The payload returned in the readdirplus call contains 'fuse_entry_out' structure thereby providing all the necessary inputs for 'faking' a lookup() operation on the spot. If the dentry and inode already existed (for e.g. in a re-run of ls -l) then just the inode attributes timeout and dentry timeout are refreshed. With a simple client->network->server implementation of a FUSE based filesystem, the following performance observations were made: Test: Performing a filesystem crawl over 20,000 files with sh# time ls -lR /mnt Without readdirplus: Run 1: 18.1s Run 2: 16.0s Run 3: 16.2s With readdirplus: Run 1: 4.1s Run 2: 3.8s Run 3: 3.8s The performance improvement is significant as it avoided 20,000 upcalls calls (lookup).

2013-01-23KVM: ARM: Inject IRQs and FIQs from userspaceChristoffer Dall1-0/+1
All interrupt injection is now based on the VM ioctl KVM_IRQ_LINE. This works semantically well for the GIC as we in fact raise/lower a line on a machine component (the gic). The IOCTL uses the follwing struct. struct kvm_irq_level { union { __u32 irq; /* GSI */ __s32 status; /* not used for KVM_IRQ_LEVEL */ }; __u32 level; /* 0 or 1 */ }; ARM can signal an interrupt either at the CPU level, or at the in-kernel irqchip (GIC), and for in-kernel irqchip can tell the GIC to use PPIs designated for specific cpus. The irq field is interpreted like this:  bits: | 31 ... 24 | 23 ... 16 | 15 ... 0 | field: | irq_type | vcpu_index | irq_number | The irq_type field has the following values: - irq_type[0]: out-of-kernel GIC: irq_number 0 is IRQ, irq_number 1 is FIQ - irq_type[1]: in-kernel GIC: SPI, irq_number between 32 and 1019 (incl.) (the vcpu_index field is ignored) - irq_type[2]: in-kernel GIC: PPI, irq_number between 16 and 31 (incl.) The irq_number thus corresponds to the irq ID in as in the GICv2 specs.

2013-01-23KVM: ARM: Initial skeleton to compile KVM supportChristoffer Dall1-0/+7
Targets KVM support for Cortex A-15 processors. Contains all the framework components, make files, header files, some tracing functionality, and basic user space API. Only supported core is Cortex-A15 for now. Most functionality is in arch/arm/kvm/* or arch/arm/include/asm/kvm_*.h.

2013-01-21libata: identify and init ZPODD devicesAaron Lu1-0/+34
The ODD can be enabled for ZPODD if the following three conditions are satisfied: 1 The ODD supports device attention; 2 The platform can runtime power off the ODD through ACPI; 3 The ODD is either slot type or drawer type. For such ODDs, zpodd_init is called and a new structure is allocated for it to store ZPODD related stuffs. And the zpodd_dev_enabled function is used to test if ZPODD is currently enabled for this ODD. A new config CONFIG_SATA_ZPODD is added to selectively build ZPODD code.

2013-01-21virtio-net: introduce a new control to set macaddrAmos Kong1-1/+7
Currently we write MAC address to pci config space byte by byte, this means that we have an intermediate step where mac is wrong. This patch introduced a new control command to set MAC address, it's atomic. VIRTIO_NET_F_CTRL_MAC_ADDR is a new feature bit for compatibility.
