2018-04-04IB/uverbs: Add action_handle flow steering specificationMatan Barak
Binding a flow_action to flow steering rule requires using a new specification. Therefore, adding such an IB_FLOW_SPEC_ACTION_HANDLE flow specification. Flow steering rules could use flow_action(s) and as of that we need to avoid deleting flow_action(s) as long as they're being used. Moreover, when the attached rules are deleted, action_handle reference count should be decremented. Introducing a new mechanism of flow resources to keep track on the attached action_handle(s). Later on, this mechanism should be extended to other attached flow steering resources like flow counters.

2018-04-04IB/uverbs: Add flow_action create and destroy verbsMatan Barak
A verbs application may receive and transmits packets using a data path pipeline. Sometimes, the first stage in the receive pipeline or the last stage in the transmit pipeline involves transforming a packet, either in order to make it easier for later stages to process it or to prepare it for transmission over the wire. Such transformation could be stripping/encapsulating the packet (i.e. vxlan), decrypting/encrypting it (i.e. ipsec), altering headers, doing some complex FPGA changes, etc. Some hardware could do such transformations without software data path intervention at all. The flow steering API supports steering a packet (either to a QP or dropping it) and some simple packet immutable actions (i.e. tagging a packet). Complex actions, that may change the packet, could bloat the flow steering API extensively. Sometimes the same action should be applied to several flows. In this case, it's easier to bind several flows to the same action and modify it than change all matching flows. Introducing a new flow_action object that abstracts any packet transformation (out of a standard and well defined set of actions). This flow_action object could be tied to a flow steering rule via a new specification. Currently, we support esp flow_action, which encrypts or decrypts a packet according to the given parameters. However, we present a flexible schema that could be used to other transformation actions tied to flow rules.

2018-04-04IB/uverbs: Add enum attribute type to ioctl() interfaceMatan Barak
Methods sometimes need to get one attribute out of a group of pre-defined attributes. This is an enum-like behavior. Since this is a common requirement, we add a new ENUM attribute to the generic uverbs ioctl() layer. This attribute is embedded in methods, like any other attributes we currently have. ENUM attributes point to an array of standard UVERBS_ATTR_PTR_IN. The user-space encodes the enum's attribute id in the id field and the internal PTR_IN attr id in the enum_data.elem_id field. This ENUM attribute could be shared by several attributes and it can get UVERBS_ATTR_SPEC_F_MANDATORY flag, stating this attribute must be supported by the kernel, like any other attribute.

2018-04-04dm: hold DM table for duration of ioctl rather than use blkdev_getMike Snitzer
Commit 519049afead ("dm: use blkdev_get rather than bdgrab when issuing pass-through ioctl") inadvertantly introduced a regression relative to users of device cgroups that issue ioctls (e.g. libvirt). Using blkdev_get() in DM's passthrough ioctl support implicitly introduced a cgroup permissions check that would fail unless care were taken to add all devices in the IO stack to the device cgroup. E.g. rather than just adding the top-level DM multipath device to the cgroup all the underlying devices would need to be allowed. Fix this, to no longer require allowing all underlying devices, by simply holding the live DM table (which includes the table's original blkdev_get() reference on the blockdevice that the ioctl will be issued to) for the duration of the ioctl. Also, bump the DM ioctl version so a user can know that their device cgroup allow workaround is no longer needed.

Currently the ACPI scan has special handling for serial bus slaves, in that it makes it the responsibility of the slave device's parent to enumerate the device. To support other types of slave devices which require the same special handling but where the bus is not strictly a serial bus, such as devices on the HiSilicon LPC controller bus, rename acpi_is_serial_bus_slave() to acpi_device_enumeration_by_parent(), so that the name can fit the wider purpose.

2018-04-04fscache: Attach the index key and aux data to the cookieDavid Howells
Attach copies of the index key and auxiliary data to the fscache cookie so that: (1) The callbacks to the netfs for this stuff can be eliminated. This can simplify things in the cache as the information is still available, even after the cache has relinquished the cookie. (2) Simplifies the locking requirements of accessing the information as we don't have to worry about the netfs object going away on us. (3) The cache can do lazy updating of the coherency information on disk. As long as the cache is flushed before reboot/poweroff, there's no need to update the coherency info on disk every time it changes. (4) Cookies can be hashed or put in a tree as the index key is easily available. This allows: (a) Checks for duplicate cookies can be made at the top fscache layer rather than down in the bowels of the cache backend. (b) Caching can be added to a netfs object that has a cookie if the cache is brought online after the netfs object is allocated. A certain amount of space is made in the cookie for inline copies of the data, but if it won't fit there, extra memory will be allocated for it. The downside of this is that live cache operation requires more memory.

2018-04-03IB/core: Refactor GID modify code for RoCEParav Pandit
Code is refactored to prepare separate functions for RoCE which can do more complex operations related to reference counting, while still maintainining code readability. This includes (a) Simplification to not perform netdevice checks and modifications for IB link layer. (b) Do not add RoCE GID entry which has NULL netdevice; instead return an error. (c) If GID addition fails at provider level add_gid(), do not add the entry in the cache and keep the entry marked as INVALID. (d) Simplify and reuse the ib_cache_gid_add()/del() routines so that they can be used even for modifying default GIDs. This avoid some code duplication in modifying default GIDs. (e) find_gid() routine refers to the data entry flags to qualify a GID as valid or invalid GID rather than depending on attributes and zeroness of the GID content. (f) gid_table_reserve_default() sets the GID default attribute at beginning while setting up the GID table. There is no need to use default_gid flag in low level functions such as write_gid(), add_gid(), del_gid(), as they never need to update the DEFAULT property of the GID entry while during GID table update. As as result of this refactor, reserved GID 0:0:0:0:0:0:0:0 is no longer searchable as described below. A unicast GID entry of 0:0:0:0:0:0:0:0 is Reserved GID as per the IB spec version 1.3 section 4.1.1, point (6) whose snippet is below. "The unicast GID address 0:0:0:0:0:0:0:0 is reserved - referred to as the Reserved GID. It shall never be assigned to any endport. It shall not be used as a destination address or in a global routing header (GRH)." GID table cache now only stores valid GID entries. Before this patch, Reserved GID 0:0:0:0:0:0:0:0 was searchable in the GID table using ib_find_cached_gid_by_port() and other similar find routines. Zero GID is no longer searchable as it shall not to be present in GRH or path recored entry as described in IB spec version 1.3 section 4.1.1, point (6), section 12.7.10 and section 12.7.20. ib_cache_update() is simplified to check link layer once, use unified locking scheme for all link layers, removed temporary gid table allocation/free logic. Additionally, (a) Expand ib_gid_attr to store port and index so that GID query routines can get port and index information from the attribute structure. (b) Expand ib_gid_attr to store device as well so that in future code when GID reference counting is done, device is used to reach back to the GID table entry.

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull namespace updates from Eric Biederman: "There was a lot of work this cycle fixing bugs that were discovered after the merge window and getting everything ready where we can reasonably support fully unprivileged fuse. The bug fixes you already have and much of the unprivileged fuse work is coming in via other trees. Still left for fully unprivileged fuse is figuring out how to cleanly handle .set_acl and .get_acl in the legacy case, and properly handling of evm xattrs on unprivileged mounts. Included in the tree is a cleanup from Alexely that replaced a linked list with a statically allocated fix sized array for the pid caches, which simplifies and speeds things up. Then there is are some cleanups and fixes for the ipc namespace. The motivation was that in reviewing other code it was discovered that access ipc objects from different pid namespaces recorded pids in such a way that when asked the wrong pids were returned. In the worst case there has been a measured 30% performance impact for sysvipc semaphores. Other test cases showed no measurable performance impact. Manfred Spraul and Davidlohr Bueso who tend to work on sysvipc performance both gave the nod that this is good enough. Casey Schaufler and James Morris have given their approval to the LSM side of the changes. I simplified the types and the code dealing with sysvipc to pass just kern_ipc_perm for all three types of ipc. Which reduced the header dependencies throughout the kernel and simplified the lsm code. Which let me work on the pid fixes without having to worry about trivial changes causing complete kernel recompiles" * 'userns-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: ipc/shm: Fix pid freeing. ipc/shm: fix up for struct file no longer being available in shm.h ipc/smack: Tidy up from the change in type of the ipc security hooks ipc: Directly call the security hook in ipc_ops.associate ipc/sem: Fix semctl(..., GETPID, ...) between pid namespaces ipc/msg: Fix msgctl(..., IPC_STAT, ...) between pid namespaces ipc/shm: Fix shmctl(..., IPC_STAT, ...) between pid namespaces. ipc/util: Helpers for making the sysvipc operations pid namespace aware ipc: Move IPCMNI from include/ipc.h into ipc/util.h msg: Move struct msg_queue into ipc/msg.c shm: Move struct shmid_kernel into ipc/shm.c sem: Move struct sem and struct sem_array into ipc/sem.c msg/security: Pass kern_ipc_perm not msg_queue into the msg_queue security hooks shm/security: Pass kern_ipc_perm not shmid_kernel into the shm security hooks sem/security: Pass kern_ipc_perm not sem_array into the sem security hooks pidns: simpler allocation of pid_* caches
