net/ipv6: Add support for path selection using hash of 5-tuple
Hardware supports multipath selection using the standard L4 5-tuple
instead of just L3 and the flow label. In addition, some network
operators prefer IPv6 path selection to use the 5-tuple. To that end,
add support to IPv6 for multipath hash policy similar to
bf4e0a3db9 ("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. This gives users a choice in
hash algorithms if they believe L3 only and the IPv6 flow label are not
sufficient for their use case.
A separate sysctl is added for IPv6, allowing IPv4 and IPv6 to use
different algorithms if desired.
The first 3 patches modify the IPv4 variant so that at the end of the
patch set the ipv4 and ipv6 implementations are direct parallels.
Patch 4 refactors the existing rt6_multipath_hash in preparation for
adding the policy option.
Patch 5 renames the existing netevent to have IPv4 in the name so ipv4
changes can be distinguished from IPv6 if the netevent handler cares.
Patch 6 adds the skb as an argument through the FIB lookup functions
to the multipath selection. Needed for the forwarding case.
Patch 7 adds the L4 hash support.
Patch 8 adds the hook for the netevent to the spectrum driver to update
the ASIC.
Patch 9 removes no longer used code.
Patch 10 adds a testcase for IPv6 multipath with L4 hash.
v3
- comments from Ido:
- removed fib_info arg in patch 1; left by mistake on rebase to net-next
- removed __get_hash_from_flowi4 declaration
- line wrap change to spectrum_router.c to maintain 80 chars
v2
- rebased to top of tree
- added refactor of fib_multipath_hash following recent change
- plumb skb through lookup functions to multipath selection
- fix sysctl setting; was missing the data set in ipv6_sysctl_net_init
- added test case
RFC to v1:
- rebase to top of net-next
- fix addr_type in hash_keys and removed flow label as noticed by Ido
- added a comment to cover letter about choice in algorithms based on
use case per Or's comments

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.

As of commit e37b1e978b ("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

sctp: clean up sctp_sendmsg
This cleanup mostly does three things:
- extract some codes into functions to make sendmsg more readable.
- tidy up some codes to avoid the unnecessary checks.
- adjust some logic so that it will be easier to add the send flags

To make it easy to review and to check if the code is compatible with
before, this patchset is to do it step by step in 9 patches.

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.

pull-request: bpf-next 2018-03-03
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Extend bpftool to build up CFG information of eBPF programs and add an
option to dump this in DOT format such that this can later be used with
DOT graphic tools (xdot, graphviz, etc) to visualize it. 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.

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.

Commit 0933a578cd ("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.
