To allow both of protocol-specific data and device-specific data attached with neighbour entry, and to eliminate size calculation cost when allocating entry, sizeof protocol-speicic data must be multiple of NEIGH_PRIV_ALIGN. On 64bit archs, sizeof(struct dn_neigh) is multiple of NEIGH_PRIV_ALIGN, but on 32bit archs, it was not. Introduce NEIGH_ENTRY_SPACE() macro to ensure that protocol-specific entry-size meets our requirement.

David Ward says: ==================== The Linux kernel currently implements the GARP VLAN Registration Protocol (GVRP) from IEEE 802.1Q-1998 (applicant-only participant). When the GVRP flag is set for a VLAN interface on a Linux host, the host advertises its membership in the VLAN to the attached bridge/ switch, so that it is not necessary to manually configure the bridge/ switch port to participate in the VLAN. GVRP has been superseded by the Multiple VLAN Registration Protocol (MVRP) in IEEE 802.1Q-2011, which addresses scalability concerns about the earlier protocol. The following patches add support for MVRP to the Linux kernel and iproute2 utility. They are based largely off of the existing implementation of GVRP, but have been modified for the new PDU structure and state machine. This implementation was tested with two Juniper EX4200 switches. ==================== Signed-off-by: NDavid Ward <david.ward@ll.mit.edu> Acked-by: NPatrick McHardy <kaber@trash.net> Signed-off-by: NDavid S.

Andy King says: ==================== In an effort to improve the out-of-the-box experience with Linux kernels for VMware users, VMware is working on readying the VM Sockets (VSOCK, formerly VMCI Sockets) (vsock) kernel module for inclusion in the Linux kernel. The purpose of this post is to acquire feedback on the vsock kernel module. Unlike previous submissions, where the new socket family was entirely reliant on VMware's VMCI PCI device (and thus VMware's hypervisor), VM Sockets is now completely[1] separated out into two parts, each in its own module: o Core socket code, which is transport-neutral and invokes transport callbacks to communicate with the hypervisor. This is vsock.ko. o A VMCI transport, which communicates over VMCI with the VMware hypervisor. This is vmw_vsock_vmci_transport.ko, and it registers with the core module as a transport. This should provide a path to introducing additional transports, for example virtio, with the ultimate goal being to make this new socket family hypervisor-neutral. [1] If Gerd tries it and determines this to be false (still), I'll ship him a keg of beer. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

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: NGeorge Zhang <georgezhang@vmware.com> Signed-off-by: NDmitry Torokhov <dtor@vmware.com> Signed-off-by: NAndy king <acking@vmware.com> Signed-off-by: NDavid S.

In sctp_auth_make_key_vector, we allocate a temporary sctp_auth_bytes structure with kmalloc instead of the sctp_auth_create_key allocator. Change this to sctp_auth_create_key as it is the case everywhere else, so that we also can properly free it via sctp_auth_key_put. This makes it easier for future code changes in the structure and allocator itself, since a single API is consistently used for this purpose. Also, by using sctp_auth_create_key we're doing sanity checks over the arguments.

Pull ARM fixes from Russell King: "I was going to hold these off until v3.8 was out, and send them with a stable tag, but as everyone else is pushing much bigger fixes which Linus is accepting, let's save people from the hastle of having to patch v3.8 back into working or use a stable kernel. Looking at the diffstat, this really is high value for its size; this is miniscule compared to how the -rc6 to tip diffstat currently looks. So, four patches in this set: - Punit Agrawal reports that the kernel no longer boots on MPCore due to a new assumption made in the GIC code which isn't true of earlier GIC designs. This is the biggest change in this set. - Punit's boot log also revealed a bunch of WARN_ON() dumps caused by the DT-ification of the GIC support without fixing up non-DT Realview - which now sees a greater number of interrupts than it did before. - A fix for the DMA coherent code from Marek which uses the wrong check for atomic allocations; this can result in spinlock lockups or other nasty effects. - A fix from Will, which will affect all Android based platforms if not applied (which use the 2G:2G VM split) - this causes particularly 'make' to misbehave unless this bug is fixed." * 'fixes' of git://git.linaro.org/people/rmk/linux-arm: ARM: 7641/1: memory: fix broken mmap by ensuring TASK_UNMAPPED_BASE is aligned ARM: DMA mapping: fix bad atomic test ARM: realview: ensure that we have sufficient IRQs available ARM: GIC: fix GIC cpumask initialization

And also: "So what I have here is some cleanups, preparations and the new MVM (multi-virtual MAC) driver itself and (this is new) some work on the transport API as well as a message flooding fix." On wl12xx, Luca says: "Lots of bugfixes and improvements in our TI wireless drivers, including support for multi-channel. Intended for 3.9." On Bluetooth, Gustavo says: "This is my first pull request to 3.9. The biggest changes here are from Johan Hedberg who made a lot of fixes in the Management interface. The issues arose due to a new test tool we wrote and the usage of the Management interface as default in BlueZ 5. The rest of the patches are more clean ups and small fixes." And also: "Here goes another batch intended for 3.9, the majority of the patch here are from Johan who is fixing many issues in the management interface that have appeared lately. The rest of the patches are just small improvements, fixes and clean ups." Along with those are the usual variety of updates/enhancements to the mwl8k, mwifiex, ath9k, rtlwifi, and rt2x00 drivers as well as a few updates for the ssb and bcma busses. I don't think there are any big headliners there. Please let me know if there are problems! ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

We have received multiple reports of mmap failures when running with a 2:2 vm split. These manifest as either -EINVAL with a non page-aligned address (ending 0xaaa) or a SEGV, depending on the application. The issue is commonly observed in children of make, which appears to use bottom-up mmap (assumedly because it changes the stack rlimit). Further investigation reveals that this regression was triggered by 394ef640 ("mm: use vm_unmapped_area() on arm architecture"), whereby TASK_UNMAPPED_BASE is no longer page-aligned for bottom-up mmap, causing get_unmapped_area to choke on misaligned addressed. This patch fixes the problem by defining TASK_UNMAPPED_BASE in terms of TASK_SIZE and explicitly aligns the result to 16M, matching the other end of the heap.
