nft_compat relies on xt_request_find_match to increment refcount of the module that provides the match/target.

2018-07-05drm/udl: fix display corruption of the last lineMikulas Patocka
The displaylink hardware has such a peculiarity that it doesn't render a command until next command is received. This produces occasional corruption, such as when setting 22x11 font on the console, only the first line of the cursor will be blinking if the cursor is located at some specific columns. When we end up with a repeating pixel, the driver has a bug that it leaves one uninitialized byte after the command (and this byte is enough to flush the command and render it - thus it fixes the screen corruption), however whe we end up with a non-repeating pixel, there is no byte appended and this results in temporary screen corruption. This patch fixes the screen corruption by always appending a byte 0xAF at the end of URB. It also removes the uninitialized byte.

However, accumulating flags to 'LD' is not compatible with the way it works; 'LD' must be passed to Kconfig to call $(ld-option,...) from Kconfig files.

2018-07-04drm/i915/gtt: Pull global wc page stash under its own lockingChris Wilson
Currently, the wc-stash used for providing flushed WC pages ready for constructing the page directories is assumed to be protected by the struct_mutex. However, we want to remove this global lock and so must install a replacement global lock for accessing the global wc-stash (the per-vm stash continues to be guarded by the vm). We need to push ahead on this patch due to an oversight in hastily removing the struct_mutex guard around the igt_ppgtt_alloc selftest. No matter, it will prove very useful (i.e. will be required) in the near future. v2: Restore the onstack stash so that we can drop the vm->mutex in future across the allocation. v3: Restore the lost pagevec_init of the onstack allocation, and repaint function names. v4: Reorder init so that we don't try and use i915_address_space before it is ininitialised.

Adjust the EIR clearing to cope with the edge triggered IIR on i965/g4x. To guarantee an edge in the ISR master error bit we temporarily mask everything in EMR. As some of the EIR bits can't even be directly cleared we also borrow a trick from i915_clear_error_registers() and permanently mask any bit that remains high. No real thought given to how we might unmask them again once the cause for the error has been clered. I suppose on pre-g4x GPU reset will reinitialize EMR from scratch.

2018-07-04sctp: fix the issue that pathmtu may be set lower than MINSEGMENTXin Long
After commit b6c5734db070 ("sctp: fix the handling of ICMP Frag Needed for too small MTUs"), sctp_transport_update_pmtu would refetch pathmtu from the dst and set it to transport's pathmtu without any check. The new pathmtu may be lower than MINSEGMENT if the dst is obsolete and updated by .get_dst() in sctp_transport_update_pmtu. In this case, it could have a smaller MTU as well, and thus we should validate it against MINSEGMENT instead. Syzbot reported a warning in sctp_mtu_payload caused by this. This patch refetches the pathmtu by calling sctp_dst_mtu where it does the check against MINSEGMENT. v1->v2: - refetch the pathmtu by calling sctp_dst_mtu instead as Marcelo's suggestion.

2018-07-04drm/amdgpu: fix user fence write race conditionNicolai Hähnle
The buffer object backing the user fence is reserved using the non-user fence, i.e., as soon as the non-user fence is signaled, the user fence buffer object can be moved or even destroyed. Therefore, emit the user fence first. Both fences have the same cache invalidation behavior, so this should have no user-visible effect.

2018-07-04net/ipv6: Revert attempt to simplify route replace and appendDavid Ahern
NetworkManager likes to manage linklocal prefix routes and does so with the NLM_F_APPEND flag, breaking attempts to simplify the IPv6 route code and by extension enable multipath routes with device only nexthops. Revert f34436a43092 and these followup patches: 6eba08c3626b ("ipv6: Only emit append events for appended routes"). ce45bded6435 ("mlxsw: spectrum_router: Align with new route replace logic") 53b562df8c20 ("mlxsw: spectrum_router: Allow appending to dev-only routes") Update the fib_tests cases to reflect the old behavior.

2018-07-04gen_stats: Fix netlink stats dumping in the presence of paddingToke Høiland-Jørgensen
The gen_stats facility will add a header for the toplevel nlattr of type TCA_STATS2 that contains all stats added by qdisc callbacks. A reference to this header is stored in the gnet_dump struct, and when all the per-qdisc callbacks have finished adding their stats, the length of the containing header will be adjusted to the right value. However, on architectures that need padding (i.e., that don't set CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS), the padding nlattr is added before the stats, which means that the stored pointer will point to the padding, and so when the header is fixed up, the result is just a very big padding nlattr. Because most qdiscs also supply the legacy TCA_STATS struct, this problem has been mostly invisible, but we exposed it with the netlink attribute-based statistics in CAKE. Fix the issue by fixing up the stored pointer if it points to a padding nlattr.
