2018-03-04mlxsw: spectrum_router: Add support for ipv6 hash policy updateDavid Ahern
Similar to 28678f07f127d ("mlxsw: spectrum_router: Update multipath hash parameters upon netevents") for IPv4, make sure the kernel and asic are using the same hash algorithm for path selection.

2018-03-04net/ipv6: Add support for path selection using hash of 5-tupleDavid Ahern
Some operators prefer IPv6 path selection to use a standard 5-tuple hash rather than just an L3 hash with the flow the label. To that end add support to IPv6 for multipath hash policy similar to bf4e0a3db97eb ("net: ipv4: add support for ECMP hash policy choice"). The default is still L3 which covers source and destination addresses along with flow label and IPv6 protocol.

2018-03-04net/ipv6: Pass skb to route lookupDavid Ahern
IPv6 does path selection for multipath routes deep in the lookup functions. The next patch adds L4 hash option and needs the skb for the forward path. To get the skb to the relevant FIB lookup functions it needs to go through the fib rules layer, so add a lookup_data argument to the fib_lookup_arg struct.

Make rt6_multipath_hash more of a direct parallel to fib_multipath_hash and reduce stack and overhead in the process: get_hash_from_flowi6 is just a wrapper around __get_hash_from_flowi6 with another stack allocation for flow_keys.

2018-03-04net/ipv4: Simplify fib_multipath_hash with optional flow keysDavid Ahern
As of commit e37b1e978bec5 ("ipv6: route: dissect flow in input path if fib rules need it") fib_multipath_hash takes an optional flow keys. If non-NULL it means the skb has already been dissected. If not set, then fib_multipath_hash needs to call skb_flow_dissect_flow_keys. Simplify the logic by setting flkeys to the local stack variable keys. Simplifies fib_multipath_hash by only have 1 set of instructions setting hash_keys.

2018-03-02libnvdimm: re-enable deep flush for pmem devices via fsync()Dave Jiang
Re-enable deep flush so that users always have a way to be sure that a write makes it all the way out to media. Writes from the PMEM driver always arrive at the NVDIMM since movnt is used to bypass the cache, and the driver relies on the ADR (Asynchronous DRAM Refresh) mechanism to flush write buffers on power failure. The Deep Flush mechanism is there to explicitly write buffers to protect against (rare) ADR failure. This change prevents a regression in deep flush behavior so that applications can continue to depend on fsync() as a mechanism to trigger deep flush in the filesystem-DAX case.

Part of the analysis performed is sub-program detection and basic-block partitioning, from Jiong. 2) Multiple enhancements for bpftool's batch mode, more specifically the parser now understands comments (#), continuation lines (\), and arguments enclosed between quotes. Also, allow to read from stdin via '-' as input file, all from Quentin. 3) Improve BPF kselftests by i) unifying the rlimit handling into a helper that is then used by all tests, and ii) add support for testing tail calls to test_verifier plus add tests covering all corner cases. The latter is especially useful for testing JITs, from Daniel. 4) Remove x64 JIT's bpf_flush_icache() since flush_icache_range() is a noop on x64, from Daniel. 5) Fix one more occasion in BPF samples where we do not detach the BPF program from the cgroup after completion, from Prashant. ==================== Signed-off-by: David S.

2018-03-02vfio: disable filesystem-dax page pinningDan Williams
Filesystem-DAX is incompatible with 'longterm' page pinning. Without page cache indirection a DAX mapping maps filesystem blocks directly. This means that the filesystem must not modify a file's block map while any page in a mapping is pinned. In order to prevent the situation of userspace holding of filesystem operations indefinitely, disallow 'longterm' Filesystem-DAX mappings. RDMA has the same conflict and the plan there is to add a 'with lease' mechanism to allow the kernel to notify userspace that the mapping is being torn down for block-map maintenance. Perhaps something similar can be put in place for vfio. Note that xfs and ext4 still report: "DAX enabled. Warning: EXPERIMENTAL, use at your own risk" ...at mount time, and resolving the dax-dma-vs-truncate problem is one of the last hurdles to remove that designation.

2018-03-02rds: Incorrect reference counting in TCP socket creationKa-Cheong Poon
Commit 0933a578cd55 ("rds: tcp: use sock_create_lite() to create the accept socket") has a reference counting issue in TCP socket creation when accepting a new connection. The code uses sock_create_lite() to create a kernel socket. But it does not do __module_get() on the socket owner. When the connection is shutdown and sock_release() is called to free the socket, the owner's reference count is decremented and becomes incorrect. Note that this bug only shows up when the socket owner is configured as a kernel module. v2: Update comments Fixes: 0933a578cd55 ("rds: tcp: use sock_create_lite() to create the accept socket") Signed-off-by: Ka-Cheong Poon <ka-cheong.poon@oracle.com> Acked-by: Santosh Shilimkar <santosh.shilimkar@oracle.com> Acked-by: Sowmini Varadhan <sowmini.varadhan@oracle.com> Signed-off-by: David S.
