Pull libnvdimm fixes from Dan Williams:
"Several fixes to the DSM (ACPI device specific method) marshaling
implementation.
I consider these urgent enough to send for 4.9 consideration since
they fix the kernel's handling of ARS (Address Range Scrub) commands.
Especially for platforms without machine-check-recovery capabilities,
successful execution of ARS commands enables the platform to
potentially break out of an infinite reboot problem if a media error
is present in the boot path. There is also a one line fix for a
device-dax read-only mapping regression.
Commits 9a901f5495e2 ("acpi, nfit: fix extended status translations
for ACPI DSMs") and 325896ffdf90 ("device-dax: fix private mapping
restriction, permit read-only") are true regression fixes for changes
introduced this cycle.
Commit efda1b5d87cb ("acpi, nfit, libnvdimm: fix / harden ars_status
output length handling") fixes the kernel's handling of zero-length
results, this never would have worked in the past, but we only just
recently discovered a BIOS implementation that emits this arguably
spec non-compliant result.
The remaining two commits are additional fall out from thinking
through the implications of a zero / truncated length result of the
ARS Status command.
In order to mitigate the risk that these changes introduce yet more
regressions they are backstopped by a new unit test in commit
a7de92dac9f0 ("tools/testing/nvdimm: unit test acpi_nfit_ctl()") that
mocks up inputs to acpi_nfit_ctl()"

This reverts commit 8ab2ae655bfe384335c5b6b0d6041e0ddce26b00.
I loved that commit because of how it explained what the problem with
newer versions of binutils were, but the actual patch itself turns out
to not work very well.
It has two problems:
- a zero CRC value isn't actually right. It happens to work for the
case where both sides of the equation fail at giving the symbol a
crc, but there are cases where the users of the exported symbol get
the right crc (due to seeing the C declarations), but the actual
exporting itself does not (due to the whole weak asm symbol issue).
So then the module load fails after all - we did have a crc for the
symbol, but we couldn't match it with the loaded module.
- it seems that the alpha assembler has special semantics for the
'.set' directive, and on alpha it doesn't actually set the value of
the specified symbol at all, it is instead used to set various
assembly modes (eg ".set noat" and ".set noreorder").
So using ".set" to set the symbol value would just cause build
failures on alpha.
I'm sure we'll find some other workaround for these issues (hopefully
that involves getting rid of modversions entirely some day, but people
are also talking about just using smarter tools). But for now we'll
just fall back on commit faaae2a58143 ("Re-enable CONFIG_MODVERSIONS in
a slightly weaker form") that just let's a missing crc through.

Given ambiguities in the ACPI 6.1 definition of the "Output (Size)"
field of the ARS (Address Range Scrub) Status command, a firmware
implementation may in practice return 0, 4, or 8 to indicate that there
is no output payload to process.
The specification states "Size of Output Buffer in bytes, including this
field.". However, 'Output Buffer' is also the name of the entire
payload, and earlier in the specification it states "Max Query ARS
Status Output Buffer Size: Maximum size of buffer (including the Status
and Extended Status fields)".
Without this fix if the BIOS happens to return 0 it causes memory
corruption as evidenced by this result from the acpi_nfit_ctl() unit
test.

1) When dcbnl_cee_fill() fails to be able to push a new netlink
attribute, it return 0 instead of an error code. From Pan Bian.
2) Two suffix handling fixes to FIB trie code, from Alexander Duyck.
3) bnxt_hwrm_stat_ctx_alloc() goes through all the trouble of setting

With binutils-2.26 and before, a weak missing symbol was kept during the
final link, and a missing CRC for an export would lead to that CRC being
treated as zero implicitly. With binutils-2.27, the crc symbol gets
dropped, and any module trying to use it will fail to load.
This sets the weak CRC symbol to zero explicitly, making it defined in
vmlinux, which in turn lets us load the modules referring to that CRC.
The comment above the __CRC_SYMBOL macro suggests that this was always
the intention, although it also seems that all symbols defined in C have
a correct CRC these days, and only the exports that are now done in
assembly need this.

====================
Netfilter fixes for net
This is a large batch of Netfilter fixes for net, they are:
1) Three patches to fix NAT conversion to rhashtable: Switch to rhlist
structure that allows to have several objects with the same key.
Moreover, fix wrong comparison logic in nf_nat_bysource_cmp() as this is
expecting a return value similar to memcmp(). Change location of
the nat_bysource field in the nf_conn structure to avoid zeroing
this as it breaks interaction with SLAB_DESTROY_BY_RCU and lead us
to crashes. From Florian Westphal.
2) Don't allow malformed fragments go through in IPv6, drop them,
otherwise we hit GPF, patch from Florian Westphal.
3) Fix crash if attributes are missing in nft_range, from Liping Zhang.
4) Fix arptables 32-bits userspace 64-bits kernel compat, from Hongxu Jia.
5) Two patches from David Ahern to fix netfilter interaction with vrf.
From David Ahern.
6) Fix element timeout calculation in nf_tables, we take milliseconds
from userspace, but we use jiffies from kernelspace. Patch from
Anders K. Pedersen.
7) Missing validation length netlink attribute for nft_hash, from
Laura Garcia.
8) Fix nf_conntrack_helper documentation, we don't default to off
anymore for a bit of time so let's get this in sync with the code.
I know is late but I think these are important, specifically the NAT
bits, as they are mostly addressing fallout from recent changes. I also
read there are chances to have -rc8, if that is the case, that would
also give us a bit more time to test this.

Hugetlb pages have ->index in size of the huge pages (PMD_SIZE or
PUD_SIZE), not in PAGE_SIZE as other types of pages. This means we
cannot user page_to_pgoff() to check whether we've got the right page
for the radix-tree index.
Let's introduce page_to_index() which would return radix-tree index for
given page.
We will be able to get rid of this once hugetlb will be switched to
multi-order entries.

When using SGs, only heap memory (memory that is valid as per
virt_addr_valid) is allowed to be referenced. The CTR DRBG used to
reference the caller-provided memory directly in an SG. In case the
caller provided stack memory pointers, the SG mapping is not considered
to be valid. In some cases, this would even cause a paging fault.
The change adds a new scratch buffer that is used unconditionally to
catch the cases where the caller-provided buffer is not suitable for
use in an SG. The crypto operation of the CTR DRBG produces its output
with that scratch buffer and finally copies the content of the
scratch buffer to the caller's buffer.
The scratch buffer is allocated during allocation time of the CTR DRBG
as its access is protected with the DRBG mutex.

Stas Nichiporovich reports oops in nf_nat_bysource_cmp(), trying to
access nf_conn struct at address 0xffffffffffffff50.
This is the result of fetching a null rhash list (struct embedded at
offset 176; 0 - 176 gets us ...fff50).
The problem is that conntrack entries are allocated from a
SLAB_DESTROY_BY_RCU cache, i.e. entries can be free'd and reused
on another cpu while nf nat bysource hash access the same conntrack entry.
Freeing is fine (we hold rcu read lock); zeroing rhlist_head isn't.
-> Move the rhlist struct outside of the memset()-inited area.

As Liping Zhang reports, after commit a8b1e36d0d1d ("netfilter: nft_dynset:
fix element timeout for HZ != 1000"), priv->timeout was stored in jiffies,
while set->timeout was stored in milliseconds. This is inconsistent and
incorrect.
Firstly, we already call msecs_to_jiffies in nft_set_elem_init, so
priv->timeout will be converted to jiffies twice.
Secondly, if the user did not specify the NFTA_DYNSET_TIMEOUT attr,
set->timeout will be used, but we forget to call msecs_to_jiffies
when do update elements.
Fix this by using jiffies internally for traditional sets and doing the
conversions to/from msec when interacting with userspace - as dynset
already does.
This is preferable to doing the conversions, when elements are inserted or
updated, because this can happen very frequently on busy dynsets.

I got offlist bug report about failing connections and high cpu usage.
This happens because we hit 'elasticity' checks in rhashtable that
refuses bucket list exceeding 16 entries.
The nat bysrc hash unfortunately needs to insert distinct objects that
share same key and are identical (have same source tuple), this cannot
be avoided.
Switch to the rhlist interface which is designed for this.
The nulls_base is removed here, I don't think its needed:
A (unlikely) false positive results in unneeded port clash resolution,
a false negative results in packet drop during conntrack confirmation,
when we try to insert the duplicate into main conntrack hash table.
Tested by adding multiple ip addresses to host, then adding
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
... and then creating multiple connections, from same source port but
different addresses:
for i in $(seq 2000 2032);do nc -p 1234 192.168.7.1 $i > /dev/null & done
(all of these then get hashed to same bysource slot)
Then, to test that nat conflict resultion is working:
nc -s 10.0.0.1 -p 1234 192.168.7.1 2000
nc -s 10.0.0.2 -p 1234 192.168.7.1 2000

Somehow I ended up with an off-by-three error in calculating the size of
the PASID and PASID State tables, which triggers allocations failures as
those tables unfortunately have to be physically contiguous.
In fact, even the *correct* maximum size of 8MiB is problematic and is
wont to lead to allocation failures. Since I have extracted a promise
that this *will* be fixed in hardware, I'm happy to limit it on the
current hardware to a maximum of 0x20000 PASIDs, which gives us 1MiB
tables — still not ideal, but better than before.
Reported by Mika Kuoppala <mika.kuoppala@linux.intel.com> and also by
Xunlei Pang <xlpang@redhat.com> who submitted a simpler patch to fix
only the allocation (and not the free) to the "correct" limit... which
was still problematic.

Prior to 3.15, there was a race between zap_pte_range() and
page_mkclean() where writes to a page could be lost. Dave Hansen
discovered by inspection that there is a similar race between
move_ptes() and page_mkclean().
We've been able to reproduce the issue by enlarging the race window with
a msleep(), but have not been able to hit it without modifying the code.
So, we think it's a real issue, but is difficult or impossible to hit in
practice.
The zap_pte_range() issue is fixed by commit 1cf35d47712d("mm: split
'tlb_flush_mmu()' into tlb flushing and memory freeing parts"). And
this patch is to fix the race between page_mkclean() and mremap().
Here is one possible way to hit the race: suppose a process mmapped a
file with READ | WRITE and SHARED, it has two threads and they are bound
to 2 different CPUs, e.g. CPU1 and CPU2. mmap returned X, then thread
1 did a write to addr X so that CPU1 now has a writable TLB for addr X
on it. Thread 2 starts mremaping from addr X to Y while thread 1
cleaned the page and then did another write to the old addr X again.
The 2nd write from thread 1 could succeed but the value will get lost.
thread 1 thread 2
(bound to CPU1) (bound to CPU2)
1: write 1 to addr X to get a
writeable TLB on this CPU
2: mremap starts
3: move_ptes emptied PTE for addr X
and setup new PTE for addr Y and
then dropped PTL for X and Y
4: page laundering for N by doing
fadvise FADV_DONTNEED. When done,
pageframe N is deemed clean.
5: *write 2 to addr X
6: tlb flush for addr X
7: munmap (Y, pagesize) to make the
page unmapped
8: fadvise with FADV_DONTNEED again
to kick the page off the pagecache
9: pread the page from file to verify
the value. If 1 is there, it means
we have lost the written 2.
*the write may or may not cause segmentation fault, it depends on
if the TLB is still on the CPU.
Please note that this is only one specific way of how the race could
occur, it didn't mean that the race could only occur in exact the above
config, e.g. more than 2 threads could be involved and fadvise() could
be done in another thread, etc.
For anonymous pages, they could race between mremap() and page reclaim:
THP: a huge PMD is moved by mremap to a new huge PMD, then the new huge
PMD gets unmapped/splitted/pagedout before the flush tlb happened for
the old huge PMD in move_page_tables() and we could still write data to
it. The normal anonymous page has similar situation.
To fix this, check for any dirty PTE in move_ptes()/move_huge_pmd() and
if any, did the flush before dropping the PTL. If we did the flush for
every move_ptes()/move_huge_pmd() call then we do not need to do the
flush in move_pages_tables() for the whole range. But if we didn't, we
still need to do the whole range flush.
Alternatively, we can track which part of the range is flushed in
move_ptes()/move_huge_pmd() and which didn't to avoid flushing the whole
range in move_page_tables(). But that would require multiple tlb
flushes for the different sub-ranges and should be less efficient than
the single whole range flush.
KBuild test on my Sandybridge desktop doesn't show any noticeable change.

The patch that removed the FIB offload infrastructure was a bit too
aggressive and also removed code needed to clean up us splitting the table
if additional rules were added. Specifically the function
fib_trie_flush_external was called at the end of a new rule being added to
flush the foreign trie entries from the main trie.
I updated the code so that we only call fib_trie_flush_external on the main
table so that we flush the entries for local from main. This way we don't
call it for every rule change which is what was happening previously.

I made some invalid assumptions with BPF_AND and BPF_MOD that could result in
invalid accesses to bpf map entries. Fix this up by doing a few things
1) Kill BPF_MOD support. This doesn't actually get used by the compiler in real
life and just adds extra complexity.
2) Fix the logic for BPF_AND, don't allow AND of negative numbers and set the
minimum value to 0 for positive AND's.
3) Don't do operations on the ranges if they are set to the limits, as they are
by definition undefined, and allowing arithmetic operations on those values
could make them appear valid when they really aren't.
This fixes the testcase provided by Jann as well as a few other theoretical

Rolf Neugebauer reported very long delays at netns dismantle.
Eric W. Biederman was kind enough to look at this problem
and noticed synchronize_net() occurring from netif_napi_del() that was
added in linux-4.5
Busy polling makes no sense for tunnels NAPI.
If busy poll is used for sessions over tunnels, the poller will need to
poll the physical device queue anyway.
netif_tx_napi_add() could be used here, but function name is misleading,
and renaming it is not stable material, so set NAPI_STATE_NO_BUSY_POLL
bit directly.
This will avoid inserting gro_cells napi structures in napi_hash[]
and avoid the problematic synchronize_net() (per possible cpu) that
Rolf reported.

10) When we hit ip6tunnel_xmit() we could have come from an ipv4 path in
a previous layer or similar, so explicitly clear the ipv6 control
block in the skb. From Eli Cooper.
11) Fix bogus sleeping inside of inet_wait_for_connect(), from WANG
Cong.
12) Correct deivce ID of T6 adapter in cxgb4 driver, from Hariprasad
Shenai.
13) Fix potential access past the end of the skb page frag array in
tcp_sendmsg(). From Eric Dumazet.
14) 'skb' can legitimately be NULL in inet{,6}_exact_dif_match(). Fix
from David Ahern.
15) Don't return an error in tcp_sendmsg() if we wronte any bytes
successfully, from Eric Dumazet.
16) Extraneous unlocks in netlink_diag_dump(), we removed the locking
but forgot to purge these unlock calls. From Eric Dumazet.
17) Fix memory leak in error path of __genl_register_family(). We leak
the attrbuf, from WANG Cong.
18) cgroupstats netlink policy table is mis-sized, from WANG Cong.
19) Several XDP bug fixes in mlx5, from Saeed Mahameed.
20) Fix several device refcount leaks in network drivers, from Johan
Hovold.
21) icmp6_send() should use skb dst device not skb->dev to determine L3
routing domain. From David Ahern.
22) ip_vs_genl_family sets maxattr incorrectly, from WANG Cong.
23) We leak new macvlan port in some cases of maclan_common_netlink()
errors. Fix from Gao Feng.
24) Similar to the icmp6_send() fix, icmp_route_lookup() should
determine L3 routing domain using skb_dst(skb)->dev not skb->dev.
Also from David Ahern.
25) Several fixes for route offloading and FIB notification handling in
mlxsw driver, from Jiri Pirko.
26) Properly cap __skb_flow_dissect()'s return value, from Eric Dumazet.
27) Fix long standing regression in ipv4 redirect handling, wrt.
validating the new neighbour's reachability. From Stephen Suryaputra
Lin.
28) If sk_filter() trims the packet excessively, handle it reasonably in
tcp input instead of exploding. From Eric Dumazet.
29) Fix handling of napi hash state when copying channels in sfc driver,
from Bert Kenward.
