Merge emailed patches from Peter Xu:
"This is a small series that I picked up from Linus's suggestion to
simplify cow handling (and also make it more strict) by checking
against page refcounts rather than mapcounts.
This makes uffd-wp work again (verified by running upmapsort)"
Note: this is horrendously bad timing, and making this kind of
fundamental vm change after -rc3 is not at all how things should work.
The saving grace is that it really is a a nice simplification:
8 files changed, 29 insertions(+), 120 deletions(-)
The reason for the bad timing is that it turns out that commit
17839856fd58 ("gup: document and work around 'COW can break either way'
issue" broke not just UFFD functionality (as Peter noticed), but Mikulas
Patocka also reports that it caused issues for strace when running in a
DAX environment with ext4 on a persistent memory setup.
And we can't just revert that commit without re-introducing the original
issue that is a potential security hole, so making COW stricter (and in
the process much simpler) is a step to then undoing the forced COW that
broke other uses.

Block layer usually doesn't support or allow zero-length bvec. Since
commit 1bdc76aea115 ("iov_iter: use bvec iterator to implement
iterate_bvec()"), iterate_bvec() switches to bvec iterator. However,
Al mentioned that 'Zero-length segments are not disallowed' in iov_iter.
Fixes for_each_bvec() so that it can move on after seeing one zero
length bvec.
Fixes: 1bdc76aea115 ("iov_iter: use bvec iterator to implement iterate_bvec()")

All three generations of Sandisk SSDs lock up hard intermittently.
Experiments showed that disabling NCQ lowered the failure rate significantly
and the kernel has been disabling NCQ for some models of SD7's and 8's,
which is obviously undesirable.
Karthik worked with Sandisk to root cause the hard lockups to trim commands
larger than 128M. This patch implements ATA_HORKAGE_MAX_TRIM_128M which
limits max trim size to 128M and applies it to all three generations of
Sandisk SSDs.

This patch fixes a few bugs:
1- We weren't taking into account sha_leftovers when adding multiple
ksvs to sha_text. As such, we were or'ing the end of ksv[j - 1] with
the beginning of ksv[j]
2- In the sha_leftovers == 2 and sha_leftovers == 3 case, bstatus was
being placed on the wrong half of sha_text, overlapping the leftover
ksv value
3- In the sha_leftovers == 2 case, we need to manually terminate the
byte stream with 0x80 since the hardware doesn't have enough room to
add it after writing M0
The upside is that all of the HDCP supported HDMI repeaters I could
find on Amazon just strip HDCP anyways, so it turns out to be _really_
hard to hit any of these cases without an MST hub, which is not (yet)
supported. Oh, and the sha_leftovers == 1 case works perfectly!

When calling into hid_map_usage(), the passed event code is
blindly stored as is, even if it doesn't fit in the associated bitmap.
This event code can come from a variety of sources, including devices
masquerading as input devices, only a bit more "programmable".
Instead of taking the event code at face value, check that it actually
fits the corresponding bitmap, and if it doesn't:
- spit out a warning so that we know which device is acting up
- NULLify the bitmap pointer so that we catch unexpected uses
Code paths that can make use of untrusted inputs can now check
that the mapping was indeed correct and bail out if not.

Frontend callback reports EAGAIN to nfnetlink to retry a command, this
is used to signal that module autoloading is required. Unfortunately,
nlmsg_unicast() reports EAGAIN in case the receiver socket buffer gets
full, so it enters a busy-loop.
This patch updates nfnetlink_unicast() to turn EAGAIN into ENOBUFS and
to use nlmsg_unicast(). Remove the flags field in nfnetlink_unicast()
since this is always MSG_DONTWAIT in the existing code which is exactly
what nlmsg_unicast() passes to netlink_unicast() as parameter.

eznps driver is supposed to be platform independent however it ends up
including stuff from inside arch/arc headers leading to rand config
build errors.
The quick hack to fix this (proper fix is too much chrun for non active
user-base) is to add following to nps platform agnostic header.
- copy AUX_IENABLE from arch/arc header
- move CTOP_AUX_IACK from arch/arc/plat-eznps/*/**

====================
rxrpc, afs: Fix probing issues
Here are some fixes for rxrpc and afs to fix issues in the RTT measuring in
rxrpc and thence the Volume Location server probing in afs:
(1) Move the serial number of a received ACK into a local variable to
simplify the next patch.
(2) Fix the loss of RTT samples due to extra interposed ACKs causing
baseline information to be discarded too early. This is a particular
problem for afs when it sends a single very short call to probe a
server it hasn't talked to recently.
(3) Fix rxrpc_kernel_get_srtt() to indicate whether it actually has seen
any valid samples or not.
(4) Remove a field that's set/woken, but never read/waited on.
(5) Expose the RTT and other probe information through procfs to make
debugging of this stuff easier.
(6) Fix VL rotation in afs to only use summary information from VL probing
and not the probe running state (which gets clobbered when next a
probe is issued).
(7) Fix VL rotation to actually return the error aggregated from the probe
errors.

Problem:
raw_local_irq_save(); // software state on
local_irq_save(); // software state off
...
local_irq_restore(); // software state still off, because we don't enable IRQs
raw_local_irq_restore(); // software state still off, *whoopsie*
existing instances:
- lock_acquire()
raw_local_irq_save()
__lock_acquire()
arch_spin_lock(&graph_lock)
pv_wait() := kvm_wait() (same or worse for Xen/HyperV)
local_irq_save()
- trace_clock_global()
raw_local_irq_save()
arch_spin_lock()
pv_wait() := kvm_wait()
local_irq_save()
- apic_retrigger_irq()
raw_local_irq_save()
apic->send_IPI() := default_send_IPI_single_phys()
local_irq_save()
Possible solutions:
A) make it work by enabling the tracing inside raw_*()
B) make it work by keeping tracing disabled inside raw_*()
C) call it broken and clean it up now
Now, given that the only reason to use the raw_* variant is because you don't
want tracing. Therefore A) seems like a weird option (although it can be done).
C) is tempting, but OTOH it ends up converting a _lot_ of code to raw just
because there is one raw user, this strips the validation/tracing off for all
the other users.
So we pick B) and declare any code that ends up doing:
raw_local_irq_save()
local_irq_save()
lockdep_assert_irqs_disabled();
broken. AFAICT this problem has existed forever, the only reason it came
up is because commit: 859d069ee1dd ("lockdep: Prepare for NMI IRQ
state tracking") changed IRQ tracing vs lockdep recursion and the
first instance is fairly common, the other cases hardly ever happen.

Sven reported that commit a21ee6055c30 ("lockdep: Change
hardirq{s_enabled,_context} to per-cpu variables") caused trouble on
s390 because their this_cpu_*() primitives disable preemption which
then lands back tracing.
On the one hand, per-cpu ops should use preempt_*able_notrace() and
raw_local_irq_*(), on the other hand, we can trivialy use raw_cpu_*()
ops for this.

Following bug was reported via irc:
nft list ruleset
set knock_candidates_ipv4 {
type ipv4_addr . inet_service
size 65535
elements = { 127.0.0.1 . 123,
127.0.0.1 . 123 }
}
..
udp dport 123 add @knock_candidates_ipv4 { ip saddr . 123 }
udp dport 123 add @knock_candidates_ipv4 { ip saddr . udp dport }
It should not have been possible to add a duplicate set entry.
After some debugging it turned out that the problem is the immediate
value (123) in the second-to-last rule.
Concatenations use 32bit registers, i.e. the elements are 8 bytes each,
not 6 and it turns out the kernel inserted
inet firewall @knock_candidates_ipv4
element 0100007f ffff7b00 : 0 [end]
element 0100007f 00007b00 : 0 [end]
Note the non-zero upper bits of the first element. It turns out that
nft_immediate doesn't zero the destination register, but this is needed
when the length isn't a multiple of 4.
Furthermore, the zeroing in nft_payload is broken. We can't use
[len / 4] = 0 -- if len is a multiple of 4, index is off by one.
Skip zeroing in this case and use a conditional instead of (len -1) / 4.
