Daniel Borkmann says: ==================== pull-request: bpf-next 2018-08-13 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Add driver XDP support for veth. This can be used in conjunction with redirect of another XDP program e.g. sitting on NIC so the xdp_frame can be forwarded to the peer veth directly without modification, from Toshiaki. 2) Add a new BPF map type REUSEPORT_SOCKARRAY and prog type SK_REUSEPORT in order to provide more control and visibility on where a SO_REUSEPORT sk should be located, and the latter enables to directly select a sk from the bpf map. This also enables map-in-map for application migration use cases, from Martin. 3) Add a new BPF helper bpf_skb_ancestor_cgroup_id() that returns the id of cgroup v2 that is the ancestor of the cgroup associated with the skb at the ancestor_level, from Andrey. 4) Implement BPF fs map pretty-print support based on BTF data for regular hash table and LRU map, from Yonghong. 5) Decouple the ability to attach BTF for a map from the key and value pretty-printer in BPF fs, and enable further support of BTF for maps for percpu and LPM trie, from Daniel. 6) Implement a better BPF sample of using XDP's CPU redirect feature for load balancing SKB processing to remote CPU. The sample implements the same XDP load balancing as Suricata does which is symmetric hash based on IP and L4 protocol, from Jesper. 7) Revert adding NULL pointer check with WARN_ON_ONCE() in __xdp_return()'s critical path as it is ensured that the allocator is present, from Björn. ==================== Signed-off-by: David S.

2018-08-13ARM: 8778/1: clkdev: don't call __of_clk_get_by_name() unnecessarily from ↵Bartosz Golaszewski
clk_get() The way this function is implemented caused some confusion when converting the TI DaVinci platform to using the common clock framework. Current kernel supports booting DaVinci boards both in device tree as well as legacy, board-file mode. In the latter, we always end up calling clk_get_sys() as of_node is NULL and __of_clk_get_by_name() returns -ENOENT. It was not obvious at first glance how clk_get(dev, NULL) will work in board-file mode since we always call __of_clk_get_by_name(). Let's make it clearer by checking if of_node is NULL and skipping right to clk_get_sys().

2018-08-13IB/uverbs: Do not check for device disassociation during ioctlJason Gunthorpe

2018-08-13IB/uverbs: Use uverbs_api to unmarshal ioctl commandsJason Gunthorpe
Convert the ioctl method syscall path to use the uverbs_api data structures. The new uapi structure includes all the same information, just in a different and more optimal way. - Use attr_bkey instead of 2 level radix trees for everything related to attributes. This includes the attribute storage, presence, and detection of missing mandatory attributes. - Avoid iterating over all attribute storage at finish, instead use find_first_bit with the attr_bkey to locate only those attrs that need cleanup. - Organize things to always run, and always rely on, cleanup. This avoids a bunch of tricky error unwind cases. - Locate the method using the radix tree, and locate the attributes using a very efficient incremental radix tree lookup - Use the precomputed destroy_bkey to handle uobject destruction - Use the precomputed allocation sizes and precomputed 'need_stack' to avoid maths in the fast path. This is optimal if userspace does not pass (many) unsupported attributes. Overall this results in much better codegen for the attribute accessors, everything is now stored in bitmaps or linear arrays indexed by attr_bkey. The compiler can compute attr_bkey values at compile time for all method attributes, meaning things like uverbs_attr_is_valid() now compile into single instruction bit tests.

2018-08-13IB/uverbs: Add a simple allocator to uverbs_attr_bundleJason Gunthorpe
This is similar in spirit to devm, it keeps track of any allocations linked to this method call and ensures they are all freed when the method exits. Further, if there is space in the internal/onstack buffer then the allocator will hand out that memory and avoid an expensive call to kalloc/kfree in the syscall path.
