2014-03-12mlx4: Implement IP based gids support for RoCE/SRIOVJack Morgenstein
Since there is no connection between the MAC/VLAN and the GID when using IP-based addressing, the proxy QP1 (running on the slave) must pass the source-mac, destination-mac, and vlan_id information separately from the GID. Additionally, the Host must pass the remote source-mac and vlan_id back to the slave, This is achieved as follows: Outgoing MADs: 1. Source MAC: obtained from the CQ completion structure (struct ib_wc, smac field). 2. Destination MAC: obtained from the tunnel header 3. vlan_id: obtained from the tunnel header. Incoming MADs 1. The source (i.e., remote) MAC and vlan_id are passed in the tunnel header to the proxy QP1. VST mode support: For outgoing MADs, the vlan_id obtained from the header is discarded, and the vlan_id specified by the Hypervisor is used instead. For incoming MADs, the incoming vlan_id (in the wc) is discarded, and the "invalid" vlan (0xffff) is substituted when forwarding to the slave.

2014-03-12mlx4: In RoCE allow guests to have multiple GIDSJack Morgenstein
The GIDs are statically distributed, as follows: PF: gets 16 GIDs VFs: Remaining GIDS are divided evenly between VFs activated by the driver. If the division is not even, lower-numbered VFs get an extra GID. For an IB interface, the number of gids per guest remains as before: one gid per guest.

2014-03-12mlx4_core: For RoCE, allow slaves to set the GID entry at that slave's indexJack Morgenstein
For IB transport, the host determines the slave GIDs. For ETH (RoCE), however, the slave's GID is determined by the IP address that the slave itself assigns to the ETH device used by RoCE. In this case, the slave must be able to write its GIDs to the HCA gid table (at the GID indices that slave "owns"). This commit adds processing for the SET_PORT_GID_TABLE opcode modifier for the SET_PORT command wrapper (so that slaves may modify their GIDS for RoCE).

2014-03-12mlx4: Adjust QP1 multiplexing for RoCE/SRIOVJack Morgenstein
This requires the following modifications: 1. Fix build_mlx4_header to properly fill in the ETH fields 2. Adjust mux and demux QP1 flow to support RoCE. This commit still assumes only one GID per slave for RoCE. The commit enabling multiple GIDs is a subsequent commit, and is done separately because of its complexity.

2014-03-12genirq: Provide irq_request/release_resources chip callbacksThomas Gleixner
For certain irq types, e.g. gpios, it's necessary to request resources before starting up the irq. This might fail so we cannot use the irq_startup() callback because we might call the irq_set_type() callback before that which does not make sense when the resource is not available. Calling irq_startup() before irq_set_type() can lead to spurious interrupts which is not desired either.

2014-03-11of: Make device nodes kobjects so they show up in sysfsGrant Likely
Device tree nodes are already treated as objects, and we already want to expose them to userspace which is done using the /proc filesystem today. Right now the kernel has to do a lot of work to keep the /proc view in sync with the in-kernel representation. If device_nodes are switched to be kobjects then the device tree code can be a whole lot simpler. It also turns out that switching to using /sysfs from /proc results in smaller code and data size, and the userspace ABI won't change if /proc/device-tree symlinks to /sys/firmware/devicetree/base. v7: Add missing sysfs_bin_attr_init() v6: Add __of_add_property() early init fixes from Pantelis v5: Rename firmware/ofw to firmware/devicetree Fix updating property values in sysfs v4: Fixed build error on Powerpc Fixed handling of dynamic nodes on powerpc v3: Fixed handling of duplicate attribute and child node names v2: switch to using sysfs bin_attributes which solve the problem of reporting incorrect property size.

2014-03-11drivers: of: add initialization code for static reserved memoryMarek Szyprowski
This patch adds support for static (defined by 'reg' property) reserved memory regions declared in device tree. Memory blocks can be reliably reserved only during early boot. This must happen before the whole memory management subsystem is initialized, because we need to ensure that the given contiguous blocks are not yet allocated by kernel. Also it must happen before kernel mappings for the whole low memory are created, to ensure that there will be no mappings (for reserved blocks). Typically, all this happens before device tree structures are unflattened, so we need to get reserved memory layout directly from fdt.

2014-03-10mm: fix GFP_THISNODE callers and clarifyJohannes Weiner
GFP_THISNODE is for callers that implement their own clever fallback to remote nodes. It restricts the allocation to the specified node and does not invoke reclaim, assuming that the caller will take care of it when the fallback fails, e.g. through a subsequent allocation request without GFP_THISNODE set. However, many current GFP_THISNODE users only want the node exclusive aspect of the flag, without actually implementing their own fallback or triggering reclaim if necessary. This results in things like page migration failing prematurely even when there is easily reclaimable memory available, unless kswapd happens to be running already or a concurrent allocation attempt triggers the necessary reclaim. Convert all callsites that don't implement their own fallback strategy to __GFP_THISNODE. This restricts the allocation a single node too, but at the same time allows the allocator to enter the slowpath, wake kswapd, and invoke direct reclaim if necessary, to make the allocation happen when memory is full.

2014-03-10vfs: atomic f_pos accesses as per POSIXLinus Torvalds
Our write() system call has always been atomic in the sense that you get the expected thread-safe contiguous write, but we haven't actually guaranteed that concurrent writes are serialized wrt f_pos accesses, so threads (or processes) that share a file descriptor and use "write()" concurrently would quite likely overwrite each others data. This violates POSIX.1-2008/SUSv4 Section XSI 2.9.7 that says: "2.9.7 Thread Interactions with Regular File Operations All of the following functions shall be atomic with respect to each other in the effects specified in POSIX.1-2008 when they operate on regular files or symbolic links: [...]" and one of the effects is the file position update. This unprotected file position behavior is not new behavior, and nobody has ever cared. Until now. Yongzhi Pan reported unexpected behavior to Michael Kerrisk that was due to this. This resolves the issue with a f_pos-specific lock that is taken by read/write/lseek on file descriptors that may be shared across threads or processes.

2014-03-10Bluetooth: Make LTK and CSRK only persisent when bondingMarcel Holtmann
In case the pairable option has been disabled, the pairing procedure does not create keys for bonding. This means that these generated keys should not be stored persistently. For LTK and CSRK this is important to tell userspace to not store these new keys. They will be available for the lifetime of the device, but after the next power cycle they should not be used anymore. Inform userspace to actually store the keys persistently only if both sides request bonding.

2014-03-10ASoC: Add a per component dai listLars-Peter Clausen
Now that every DAI has a component we can track the DAIs on a per component basis. This simplifies the DAI lookup when we are only interested in DAIs of a specific component and also makes it possible to have multiple components with the same parent device and also register DAIs.

2014-03-10selinux: add gfp argument to security_xfrm_policy_alloc and fix callersNikolay Aleksandrov
security_xfrm_policy_alloc can be called in atomic context so the allocation should be done with GFP_ATOMIC. Add an argument to let the callers choose the appropriate way. In order to do so a gfp argument needs to be added to the method xfrm_policy_alloc_security in struct security_operations and to the internal function selinux_xfrm_alloc_user. After that switch to GFP_ATOMIC in the atomic callers and leave GFP_KERNEL as before for the rest. The path that needed the gfp argument addition is: security_xfrm_policy_alloc -> security_ops.xfrm_policy_alloc_security -> all users of xfrm_policy_alloc_security (e.g. selinux_xfrm_policy_alloc) -> selinux_xfrm_alloc_user (here the allocation used to be GFP_KERNEL only) Now adding a gfp argument to selinux_xfrm_alloc_user requires us to also add it to security_context_to_sid which is used inside and prior to this patch did only GFP_KERNEL allocation. So add gfp argument to security_context_to_sid and adjust all of its callers as well.

2014-03-09Bluetooth: Add support for handling signature resolving keysMarcel Holtmann
The connection signature resolving key (CSRK) is used for attribute protocol signed write procedures. This change generates a new local key during pairing and requests the peer key as well. Newly generated key and received key will be provided to userspace using the New Signature Resolving Key management event. The Master CSRK can be used for verification of remote signed write PDUs and the Slave CSRK can be used for sending signed write PDUs to the remote device.
