First round of IIO new device support, features and cleanups for the 4.10 cycle.
Fair number of outreachy related patches in here. Some of these may well have already been picked up by Greg but git will sort that out for us. Also some good staging cleanup work from other sources. Thanks Brian and Lars in particular for this. New device support * ACCES 104-quad-8 - New driver for this 8 channel encoder input board. Lots of new ABI with this one. * AD7766 - New driver supporting AD7766, AD7766-1, AD7766-2, AD7767, AD7767-1 and AD7767-2 24 bit ADCs. * dmard 10 - New driver for this 3 axis accelerometer. * Honeywell ABP pressure sensors. - New driver covering 56 parts in this series (too many to list here!) * HTS221 - New driver to support this relative humidiy and temperature device. * LMP91000 - New driver for this potentiostat (form of chemical sensor). Nice example of use of the buffered consumer interfaces and the use of a consumer provided trigger. * MiraMEMS DA311 - New driver for this 3 axis accelerometer. * MiraMEMS DA280 - New driver for this 3 axis accelerometer. Follow up caught up with vendor prefixes for these. Staging graduations * isl29018 light sensor - Fixes and cleanups listed below (thanks for your hard work on this Brian!) * sca3000 - Fixes and cleanups listed below. This was one of the small set of drivers that went into staging when IIO was first added. Turns out it had a few bugs and needed to be brought into the modern era! Not clear if I am the only person who actually has one of these still wired to a board. New features (Core) - Add an iio_trigger_validate_own_device helper which relies on the device and trigger having the same parent. Convenient to have this for some of the more complex trigger / device interactions. Was hand rolled in a few drivers already so good to bring it into the core. - Add an iio_read_channel_offset in kernel access helper (similar to the existing one for scale). - IIO_ATTR_{RO, WO, RW} and IIO_DEVICE_ATTR_{RO, WO, RW} macros. These lead some rather contrived function naming, but there is no denying they do reduced boilerplate. I'm going to resist their introduction in drivers 'unless' they form part of a larger set of cleanups. - Counter channel type and index type. New features (Drivers) * hdc100x - Triggered buffer support. * mcp4725 - Device tree bindings and support. - Voltage reference selection. * ti-adc0832 - Triggered buffer support. * ti-adc161s626 - Add regulator support allowing _scale and _offset values to be established and exported. New features (Tools) * iio_generic_buffer - -A option to force enable all channels rather than faulting if some are already enabled (like -a does). Followup patches tidied this support up. Cleanups (Core) - Use kmalloc_array in iio_scan_mask_set. - Take event_attrs field of iio_info structure constant - Staging todo list updates. Most of it was long done. - MAINTAINERS had a wrong directory listing. Cleanups (Drivers) * Missing i2c trivial devices entries. * ad5592r - Fix an endian type related sparse warnings. * ad7150 - Constify the event attribute_group structures. * ad7152 - Add some blank lines to improve readability. - Sampling frequency control via chan-info element rather than hand rolled attributes. - add a new lock to avoid use of mlock for non state change related locking. * ad7280 - Constify atrribute_group structure (second patch covers the event ones) * ad7606 (Lars is driving most of the cleanup on this with some additions from Eva) - Fix improper setting of oversampling pins. This has been broken a very long time in this staging driver, so not going to push this back to stable. - Implement oversampling configuration via the chan_info mask element. - Remove an unused int_vref_mv field. - Remove a reundant name field from ad7606_chip_info. - Remove default device configuration from platform_data in favour of whatever the power on defaults are. - Remove out of band error reporting in the kernel log as not providing much information. - Fix oversampling ratio by having 1 be the value for no oversampling. - Avoid allocating buffer for each data capture. - Factor out common code between periodic and one-shot capture. - Move set_drvdat into common code. - Let the common probe function return int rather than jumping through an ERR_PTR. - Pass struct device * into common remove to simplify code. - Always run trigger handler only once per event (no one can remember why it was being possibly done twice). - Move over to the GPIO descriptor API to shorten and clarify code. - Move the buffer code into the main file as it's not optional and is now rather short in this driver. - Fix the naming of the supply regulator. - Rework regulator handling to handle errors including deferred probing. - Tidy up a ptr_err or 0 return. * ad7746 - Sampling frequency control via info_mask element rather than hand rolled * ad7758 - Sampling frequency control via info_mask element rather than hand rolled attributes. * ad7816 - Constify the event attribute_group structure. * adt7316 - Constify the event attribute group structures. * ak8974 - Cleanup some sparse warnings about endian types. * ak8975 - Cleanup some sparse warnings about endian types. * bmi160 - Spare endian warning cleanups. * isl29018 (towards staging graduation) - Remove unusedvariables and defines. - Improve consistency of error handling. - Signed / unsigned comparison fixes. - Use the IIO_DEVICE_ATTR_{RO, RW} macros - Fix a race in in_illuminance_scale_available_show. - Cleanup exit points of _read_raw - Sanity check if in suspended state during a write_raw call as was already done for read_raw. - Document device tree bidnings. - Document infrared supression controls. - Add some newlines to improve readability and drop one that shouldn't be there. - Fix a poorly named functions name. - Fix multiline coment syntax. - Tidy up a pair or return statements by unifying them. - Rename description in Kconfig for consistency with similar drivers. * lidar - cleanup power management by dropping unnecessary call. * ltr501 - Use the claim_direct_mode helpers. Fix a race condition along the way. * max1027 - Fix a dubious x | !y sparse warning. - Use the new iio_trigger_validate_own_device helper. * max440000 - Clean up some sparse warnings about endian types. * mcp4725 - Use the regulator framework to establish the reference voltage rather than getting it from platform data. - Tidy up a comment typo. - Fix a wrong PTR_ERR query (wrong regulator). * mma7660 - Take a mma7660_nscale static. * mma8452 - Use the new iio_trigger_validate_own_device helper. - Use claim_direct_mode helpers - fix a race condition along the way. * mpl3115 - Use claim_direct_mode helpers - fix a race condition along the way. * ms65611 - Tidy up regulator error handling and clean out a static warning in the mix. * sca3000 - Avoid a potential unitialized variable if a hardware read returns a value that isn't actually supported (mostly warning supression). - Fix a use before setting of the indio_dev->buffer pointer. Broken for a very long time so not going to rush this into stable. - Merge buffer file with core file. We used to always split these. Sometimes it's just not worth the hassle. In this case the device's main feature is it's hardware fifos so unlikely anyone would want to run it without. - Drop the sca3000_register_ring_funcs function as it's a pointless wrapper once we have only one file. - Fix cleaning of flag + setting of size of scan. Without this you can't start the buffer twice and expect sensible (or any) results. Again, broken for a long time so not heading for stable. - Drop the custom watershed setting ABI - for now we'll just support one value. - Move to a hybrid hard / soft buffer design (how we've been doing it for similar devices for a while now!) - Cleanup some unusued variables. - Use a fake channel to support core handling of freefall event registration. - Cleanup the register defines. - Fix an off by one error in axis due to IIO_NO_MOD taking up the 0 value. Been broken since first admission of IIO to the staging tree. - Add readback of the 3db low pass filter frequency and later writing allowing droppign of custom measurement mode attributes as they can be represented by the filter choices that is their main characteristic. - Drop non standard revision attr and replace with dev_info on probe. - Avoid a race in probe. - Various formatting fixes. - Kernel-docify docs that were very nearly in the write format. * tsl2583 - Constify attribute_group structure. * zpa2326 - Drop a redundant DEBUG ifdef. Cleanups (Tools) * iio_generic_buffer - Fix the ? arguement. Previously it sort of worked as you got the help message as a result of it not recognising the arguement. -----BEGIN PGP SIGNATURE----- iQIuBAABCAAYBQJYDSX+ERxqaWMyM0BrZXJuZWwub3JnAAoJEFSFNJnE9BaIQSEP /2HRMqDXeIh2N0oVLBFK5pEaAZ52tjsEmf1XgfCJ3D1PczS0vzqkFKuG/078BU3v e9MTj39sF1EOyGJv4mdfnHygLPvjaTU/A6HoIaP1t9cUgSQ1jzPN0tO8/Hj/ESlU U3mNgUNUIa9cnVIfWk2cPJqgKJ/w52vRk00yRnOKZjHZkxbYQq9rPJ7ks12jQSGT IBEipiYMnRovc2w4NWbAry5pAXBmttVFKyi5FZ7uIM5EH34+SAY6laXSoZQl8E74 LKgIwdPUn9yeujyX6ohBFRFloOf/4VYedV6NIUz8k5BzuTeAJcp4DSMLXSWIwZVd sdza6el3Tt0MkjIgioTg7N07FvatbQVIsnWnLjLb/zpMjGQPigfTnIi7kYcH3wHx NwpTy1MZg5U571LOYXsEhNvIFiQICoV6+8d/PzrO1J+rphuQYreOm0WzjvIqW4q/ dU2uCAMOHd82gjm9QrKjvrc+4M3oGc3ENE/i5P2YNQhdkdNKp9PMWgL6RO9QXgeQ 9TrjbDr9OSFLatZg5IswWFa5CHL9AZ6OuvaRyx/8n5cBdY3n8+wMIowRQJlMUdGY Aa5ByntMsvhwCu+M1+fDihZyx4suTNvW7+Emqd/8lCb+BRjHoamBb6uGBGx6Txvy 6TPluNWE+cK5Tjkrn+jDbTzhwdaaSRtO4ECRwxXYAqfn =ZRUt -----END PGP SIGNATURE----- Merge tag 'iio-for-4.10a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: First round of IIO new device support, features and cleanups for the 4.10 cycle.

Some RDMA work and some good bugfixes, and two new features that could
benefit from user testing: Anna Schumacker contributed a simple NFSv4.2 COPY implementation. COPY is already supported on the client side, so a call to copy_file_range() on a recent client should now result in a server-side copy that doesn't require all the data to make a round trip to the client and back. Jeff Layton implemented callbacks to notify clients when contended locks become available, which should reduce latency on workloads with contended locks. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJX/mcsAAoJECebzXlCjuG+MU0P/3SzTLGYXU5yOTAorx255/uf fUVKQQhTzzaA2xj3gWWWztYx3y0ZJUVgwU56a+Ap5Z8/goqDQ78H+ePEc+MG7BT/ /UXS/bITvt0MP/dvPrDzhSltvqx/wpelLPBo29hGLlAQ2dsnD4Y75IbOOQccWqcC iD2v6x7lnpWZ7j9Zhwzg/JNQHwISIb7tiLoYBjfcdNDEMU76KIyhxD0Cx9MSeBzH 9Rq/oEdwGDFS5WqVfNe2jxbngoauq1IupziQ2eQGv2D/POyXCx8fphoYjDz1XaW8 PxaJtJtM2owPGG+z2CxklJqNaS1Z4F+oppjg+nf4i/ibxmIBaTy8NluASX3vMh69 CDO1+ly+TiF0l1VqMOQJWRnqn1qGk6fLpF6P1Ac62B0oWpeLGU7nmik7XN1ORgsi 8ksxRKNAWeprZo3wl5xNrADu/wlZ7XCJTc4QoHEgYT04aHF+j8EMCHv+mtZ8+Bwn WWiA8iItZOgXV4vitCRJlvsixjYvmF3djPIoI2Lt5KDWIg+eL89sKwzTALSfeC4m Vjb0svzPX1MmZCNP1rCStFbl3gZYXZyqPk+uA6M7H8mjAjVeKxRPowWpMBgvYZHr FjCPb878bAuqCeBVbIyOLLcKWBLTw8PsUWZAor3gNg454JGkMjLUyJ/S22Cz5Nbo HdjoiTJtbPrHnCwTMXwa =nozl -----END PGP SIGNATURE----- Merge tag 'nfsd-4.9' of git://linux-nfs.org/~bfields/linux Pull nfsd updates from Bruce Fields: "Some RDMA work and some good bugfixes, and two new features that could benefit from user testing: - Anna Schumacker contributed a simple NFSv4.2 COPY implementation.

This pullreq contains the new shared data extents feature for XFS. Given the complexity and size of this change I am expecting - like the addition of reverse mapping last cycle - that there will be some follow-up bug fixes and cleanups around the -rc3 stage for issues that I'm sure will show up once the code hits a wider userbase. What it is: At the most basic level we are simply adding shared data extents to XFS - i.e. a single extent on disk can now have multiple owners. To do this we have to add new on-disk features to both track the shared extents and the number of times they've been shared. This is done by the new "refcount" btree that sits in every allocation group. When we share or unshare an extent, this tree gets updated. Along with this new tree, the reverse mapping tree needs to be updated to track each owner or a shared extent. This also needs to be updated ever share/unshare operation. These interactions at extent allocation and freeing time have complex ordering and recovery constraints, so there's a significant amount of new intent-based transaction code to ensure that operations are performed atomically from both the runtime and integrity/crash recovery perspectives. We also need to break sharing when writes hit a shared extent - this is where the new copy-on-write implementation comes in. We allocate new storage and copy the original data along with the overwrite data into the new location. We only do this for data as we don't share metadata at all - each inode has it's own metadata that tracks the shared data extents, the extents undergoing CoW and it's own private extents. Of course, being XFS, nothing is simple - we use delayed allocation for CoW similar to how we use it for normal writes. ENOSPC is a significant issue here - we build on the reservation code added in 4.8-rc1 with the reverse mapping feature to ensure we don't get spurious ENOSPC issues part way through a CoW operation. These mechanisms also help minimise fragmentation due to repeated CoW operations. To further reduce fragmentation overhead, we've also introduced a CoW extent size hint, which indicates how large a region we should allocate when we execute a CoW operation. With all this functionality in place, we can hook up .copy_file_range, .clone_file_range and .dedupe_file_range and we gain all the capabilities of reflink and other vfs provided functionality that enable manipulation to shared extents. We also added a fallocate mode that explicitly unshares a range of a file, which we implemented as an explicit CoW of all the shared extents in a file. As such, it's a huge chunk of new functionality with new on-disk format features and internal infrastructure. It warns at mount time as an experimental feature and that it may eat data (as we do with all new on-disk features until they stabilise). We have not released userspace suport for it yet - userspace support currently requires download from Darrick's xfsprogs repo and build from source, so the access to this feature is really developer/tester only at this point. Initial userspace support will be released at the same time the kernel with this code in it is released. The new code causes 5-6 new failures with xfstests - these aren't serious functional failures but things the output of tests changing slightly due to perturbations in layouts, space usage, etc. OTOH, we've added 150+ new tests to xfstests that specifically exercise this new functionality so it's got far better test coverage than any functionality we've previously added to XFS. Darrick has done a pretty amazing job getting us to this stage, and special mention also needs to go to Christoph (review, testing, improvements and bug fixes) and Brian (caught several intricate bugs during review) for the effort they've also put in. Summary: - unshare range (FALLOC_FL_UNSHARE) support for fallocate - copy-on-write extent size hints (FS_XFLAG_COWEXTSIZE) for fsxattr interface - shared extent support for XFS - copy-on-write support for shared extents - copy_file_range support - clone_file_range support (implements reflink) - dedupe_file_range support - defrag support for reverse mapping enabled filesystems" * tag 'xfs-reflink-for-linus-4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs: (71 commits) xfs: convert COW blocks to real blocks before unwritten extent conversion xfs: rework refcount cow recovery error handling xfs: clear reflink flag if setting realtime flag xfs: fix error initialization xfs: fix label inaccuracies xfs: remove isize check from unshare operation xfs: reduce stack usage of _reflink_clear_inode_flag xfs: check inode reflink flag before calling reflink functions xfs: implement swapext for rmap filesystems xfs: refactor swapext code xfs: various swapext cleanups xfs: recognize the reflink feature bit xfs: simulate per-AG reservations being critically low xfs: don't mix reflink and DAX mode for now xfs: check for invalid inode reflink flags xfs: set a default CoW extent size of 32 blocks xfs: convert unwritten status of reverse mappings for shared files xfs: use interval query for rmap alloc operations on shared files xfs: add shared rmap map/unmap/convert log item types xfs: increase log reservations for reflink ... |

libnvdimm for 4.9
* PMEM sub-division support: Allow a single PMEM region to be divided into multiple namespaces. Originally, ~2 years ago, it was thought that partitions of a /dev/pmemX block device could handle sub-allocations of persistent memory for different use cases. With the decision to not support DAX mappings of raw block-devices, and the genesis of device-dax, the need for having multiple pmem-namespace per region has grown. * Device-DAX unified inode: In support of dynamic-resizing of a device-dax instance the kernel arranges for all mappings of a device-dax node to share the same inode. This allows unmap / truncate / invalidation events to affect all instances of the device similar to the behavior of mmap on block devices. * Hardware error scrubbing reworks: The original address-range-scrub + badblocks tracking solution allowed clearing entries at the individual namespace level, but it failed to clear the internal list of media errors maintained at the bus level. The result was that the next scrub or namespace disable/re-enable event would restore the cleared badblocks, but now that is fixed. The v4.8 kernel introduced an auto-scrub-on-machine-check behavior to repopulate the badblocks list. Now, in v4.9, the auto-scrub behavior can be disabled and simply arrange for the error reported in the machine-check to be added to the list. * DIMM health-event notification support: ACPI 6.1 defines a notification event code that can be send to ACPI NVDIMM devices. A poll(2) capable file descriptor for these events can be obtained from the nmemX/nfit/flags sysfs-attribute of a libnvdimm memory device. * Miscellaneous fixes: NVDIMM-N probe error, device-dax build error, and a change to dedup the flush hint list to not flush the memory controller more than necessary. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJX/B2oAAoJEB7SkWpmfYgCe3YQAJiH4ZYRxr6HeJzVQltbhB2k qyLC+7vIssefPPqn/Wycc3aHJjyk2ktetmFyjYE1q/vlJJWCG3y/ACfz2SZANXXx 2tgLsI+3dXZaGgIxRsZF8MsB672owqCbzJHbbmTRu3EtgMplagfh27G7HFZxt4Jd FyKnRkknYsCEbHry/s0aRcZWPmacu5v1TDJyWgd0edNTG32GrKOtwxWrWEPRDJE1 dIK5JjPaDwMFMKjV6lgRuBVlsMKCzIC4YjSYZZmN/Mf/JCJBJuPSlkYEdGZ+xx84 /ZmKrE/XRPr7469f66QyD8iRtGAQ9OparhChbuzCagCHRAwgYy4yQGbK7rk0lwUM 18jysZU8NJxp4jEJIt0u2ap6W9ySePX5Bm+3CSwqxT0Ernew2AUJDLIw9f1hAAbX rippSWyHp0JtBTjOeaV2ZY1LJlm+J//AycbFo51lAERHoX5zPimHL730EM8mJu7y fIbFpau3fjob+ovQMXMIYam8C/MpTqAvcjpBFhkSlsY7q/l+ARgFpjYpg9qVir8g v6PZ0UoGBhQvD2lTNTUjaCaHOc+sjo8PLeNI1ZsFebh63rF3k5sOLOk7wXllf8z5 jQBnYtYnPCJI67BLLZmwWzoBb0HpCbcPp9/0/c1rdLTcAo+3gi6SY4pVJgznxCZZ +fkeOvSutJ687tFMarc1 =SenK -----END PGP SIGNATURE----- Merge tag 'libnvdimm-for-4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm updates from Dan Williams: "Aside from the recently added pmem sub-division support these have been in -next for several releases with no reported issues.

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull namespace updates from Eric Biederman: "This set of changes is a number of smaller things that have been overlooked in other development cycles focused on more fundamental change. The devpts changes are small things that were a distraction until we managed to kill off DEVPTS_MULTPLE_INSTANCES. There is an trivial regression fix to autofs for the unprivileged mount changes that went in last cycle. A pair of ioctls has been added by Andrey Vagin making it is possible to discover the relationships between namespaces when referring to them through file descriptors. The big user visible change is starting to add simple resource limits to catch programs that misbehave. With namespaces in general and user namespaces in particular allowing users to use more kinds of resources, it has become important to have something to limit errant programs. Because the purpose of these limits is to catch errant programs the code needs to be inexpensive to use as it always on, and the default limits need to be high enough that well behaved programs on well behaved systems don't encounter them. To this end, after some review I have implemented per user per user namespace limits, and use them to limit the number of namespaces. The limits being per user mean that one user can not exhause the limits of another user. The limits being per user namespace allow contexts where the limit is 0 and security conscious folks can remove from their threat anlysis the code used to manage namespaces (as they have historically done as it root only). At the same time the limits being per user namespace allow other parts of the system to use namespaces. Namespaces are increasingly being used in application sand boxing scenarios so an all or nothing disable for the entire system for the security conscious folks makes increasing use of these sandboxes impossible. There is also added a limit on the maximum number of mounts present in a single mount namespace. It is nontrivial to guess what a reasonable system wide limit on the number of mount structure in the kernel would be, especially as it various based on how a system is using containers. A limit on the number of mounts in a mount namespace however is much easier to understand and set. In most cases in practice only about 1000 mounts are used. Given that some autofs scenarious have the potential to be 30,000 to 50,000 mounts I have set the default limit for the number of mounts at 100,000 which is well above every known set of users but low enough that the mount hash tables don't degrade unreaonsably. These limits are a start. I expect this estabilishes a pattern that other limits for resources that namespaces use will follow. There has been interest in making inotify event limits per user per user namespace as well as interest expressed in making details about what is going on in the kernel more visible" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (28 commits) autofs: Fix automounts by using current_real_cred()->uid mnt: Add a per mount namespace limit on the number of mounts netns: move {inc,dec}_net_namespaces into #ifdef nsfs: Simplify __ns_get_path tools/testing: add a test to check nsfs ioctl-s nsfs: add ioctl to get a parent namespace nsfs: add ioctl to get an owning user namespace for ns file descriptor kernel: add a helper to get an owning user namespace for a namespace devpts: Change the owner of /dev/pts/ptmx to the mounter of /dev/pts devpts: Remove sync_filesystems devpts: Make devpts_kill_sb safe if fsi is NULL devpts: Simplify devpts_mount by using mount_nodev devpts: Move the creation of /dev/pts/ptmx into fill_super devpts: Move parse_mount_options into fill_super userns: When the per user per user namespace limit is reached return ENOSPC userns; Document per user per user namespace limits. mntns: Add a limit on the number of mount namespaces. netns: Add a limit on the number of net namespaces cgroupns: Add a limit on the number of cgroup namespaces ipcns: Add a limit on the number of ipc namespaces ... |

Btrfs: catch invalid free space trees
There are two separate issues that can lead to corrupted free space trees. 1. The free space tree bitmaps had an endianness issue on big-endian systems which is fixed by an earlier patch in this series. 2. btrfs-progs before v4.7.3 modified filesystems without updating the free space tree. To catch both of these issues at once, we need to force the free space tree to be rebuilt. To do so, add a FREE_SPACE_TREE_VALID compat_ro bit. If the bit isn't set, we know that it was either produced by a broken big-endian kernel or may have been corrupted by btrfs-progs. This also provides us with a way to add rudimentary read-write support for the free space tree to btrfs-progs: it can just clear this bit and have the kernel rebuild the free space tree.

iio: Implement counter channel type and info constants
Quadrature encoders, such as rotary encoders and linear encoders, are devices which are capable of encoding the relative position and direction of motion of a shaft. This patch introduces several IIO constants for supporting quadrature encoder counter devices.

fuse: Add posix ACL support
Add a new INIT flag, FUSE_POSIX_ACL, for negotiating ACL support with userspace. When it is set in the INIT response, ACL support will be enabled. ACL support also implies "default_permissions". When ACL support is enabled, the kernel will cache and have responsibility for enforcing ACLs. ACL xattrs will be passed to userspace, which is responsible for updating the ACLs in the filesystem, keeping the file mode in sync, and inheritance of default ACLs when new filesystem nodes are created.

netfilter: nft_log: complete NFTA_LOG_FLAGS attr support
NFTA_LOG_FLAGS attribute is already supported, but the related NF_LOG_XXX flags are not exposed to the userspace. So we cannot explicitly enable log flags to log uid, tcp sequence, ip options and so on, i.e. such rule "nft add rule filter output log uid" is not supported yet. So move NF_LOG_XXX macro definitions to the uapi/../nf_log.h. In order to keep consistent with other modules, change NF_LOG_MASK to refer to all supported log flags. On the other hand, add a new NF_LOG_DEFAULT_MASK to refer to the original default log flags. Finally, if user specify the unsupported log flags or NFTA_LOG_GROUP and NFTA_LOG_FLAGS are set at the same time, report EINVAL to the userspace.

netfilter: xt_hashlimit: Create revision 2 to support higher pps rates
Create a new revision for the hashlimit iptables extension module. Rev 2 will support higher pps of upto 1 million, Version 1 supports only 10k. To support this we have to increase the size of the variables avg and burst in hashlimit_cfg to 64-bit. Create two new structs hashlimit_cfg2 and xt_hashlimit_mtinfo2 and also create newer versions of all the functions for match, checkentry and destroy. Some of the functions like hashlimit_mt, hashlimit_mt_check etc are very similar in both rev1 and rev2 with only minor changes, so I have split those functions and moved all the common code to a *_common function.

net: Update API for VF vlan protocol 802.1ad support
Introduce new rtnl UAPI that exposes a list of vlans per VF, giving the ability for user-space application to specify it for the VF, as an option to support 802.1ad. We adjusted IP Link tool to support this option. For future use cases, the new UAPI supports multiple vlans. For now we limit the list size to a single vlan in kernel. Add IFLA_VF_VLAN_LIST in addition to IFLA_VF_VLAN to keep backward compatibility with older versions of IP Link tool. Add a vlan protocol parameter to the ndo_set_vf_vlan callback. We kept 802.1Q as the drivers' default vlan protocol. Suitable ip link tool command examples: Set vf vlan protocol 802.1ad: ip link set eth0 vf 1 vlan 100 proto 802.1ad Set vf to VST (802.1Q) mode: ip link set eth0 vf 1 vlan 100 proto 802.1Q Or by omitting the new parameter ip link set eth0 vf 1 vlan 100 Signed-off-by: Moshe Shemesh <moshe@mellanox.com> Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: David S.
