In commit 170d13ca3a ("x86: re-introduce non-generic memcpy_{to,from}io")
I made our copy from IO space use a separate copy routine rather than
rely on the generic memcpy. I did that because our generic memory copy
isn't actually well-defined when it comes to internal access ordering or
alignment, and will in fact depend on various CPUID flags.
In particular, the default memcpy() for a modern Intel CPU will
generally be just a "rep movsb", which works reasonably well for
medium-sized memory copies of regular RAM, since the CPU will turn it
into fairly optimized microcode.
However, for non-cached memory and IO, "rep movs" ends up being
horrendously slow and will just do the architectural "one byte at a
time" accesses implied by the movsb.
At the other end of the spectrum, if you _don't_ end up using the "rep
movsb" code, you'd likely fall back to the software copy, which does
overlapping accesses for the tail, and may copy things backwards.
Again, for regular memory that's fine, for IO memory not so much.
The thinking was that clearly nobody really cared (because things
worked), but some people had seen horrible performance due to the byte
accesses, so let's just revert back to our long ago version that dod
"rep movsl" for the bulk of the copy, and then fixed up the potentially
last few bytes of the tail with "movsw/b".
Interestingly (and perhaps not entirely surprisingly), while that was
our original memory copy implementation, and had been used before for
IO, in the meantime many new users of memcpy_*io() had come about. And
while the access patterns for the memory copy weren't well-defined (so
arguably _any_ access pattern should work), in practice the "rep movsb"
case had been very common for the last several years.
In particular Jarkko Sakkinen reported that the memcpy_*io() change
resuled in weird errors from his Geminilake NUC TPM module.
And it turns out that the TPM TCG accesses according to spec require
that the accesses be
(a) done strictly sequentially
(b) be naturally aligned
otherwise the TPM chip will abort the PCI transaction.
And, in fact, the tpm_crb.c driver did this:
memcpy_fromio(buf, priv->rsp, 6);
...
memcpy_fromio(&buf[6], &priv->rsp[6], expected - 6);
which really should never have worked in the first place, but back
before commit 170d13ca3a it *happened* to work, because the
memcpy_fromio() would be expanded to a regular memcpy, and
(a) gcc would expand the first memcpy in-line, and turn it into a
4-byte and a 2-byte read, and they happened to be in the right
order, and the alignment was right.
(b) gcc would call "memcpy()" for the second one, and the machines that
had this TPM chip also apparently ended up always having ERMS
("Enhanced REP MOVSB/STOSB instructions"), so we'd use the "rep
movbs" for that copy.
In other words, basically by pure luck, the code happened to use the
right access sizes in the (two different!) memcpy() implementations to
make it all work.
But after commit 170d13ca3a, both of the memcpy_fromio() calls
resulted in a call to the routine with the consistent memory accesses,
and in both cases it started out transferring with 4-byte accesses.
Which worked for the first copy, but resulted in the second copy doing a
32-bit read at an address that was only 2-byte aligned.
Jarkko is actually fixing the fragile code in the TPM driver, but since
this is an excellent example of why we absolutely must not use a generic
memcpy for IO accesses, _and_ an IO-specific one really should strive to
align the IO accesses, let's do exactly that.
Side note: Jarkko also noted that the driver had been used on ARM
platforms, and had worked. That was because on 32-bit ARM, memcpy_*io()
ends up always doing byte accesses, and on 64-bit ARM it first does byte
accesses to align to 8-byte boundaries, and then does 8-byte accesses
for the bulk.
So ARM actually worked by design, and the x86 case worked by pure luck.
We *might* want to make x86-64 do the 8-byte case too. That should be a
pretty straightforward extension, but let's do one thing at a time. And
generally MMIO accesses aren't really all that performance-critical, as
shown by the fact that for a long time we just did them a byte at a
time, and very few people ever noticed.

Revert commit 3d71746c42 ("PCI: armada8k: Add support for gpio controlled
reset signal").
That commit breaks boot on Macchiatobin board when a Mellanox NIC is
present in the PCIe slot.
It turns out that full reset cycle requires first comphy serdes
initialization. Reset signal toggle without comphy initialization makes
access to PCI configuration registers stall indefinitely. U-Boot toggles
the Macchiatobin PCIe reset line already at boot, after initializing the
comphy serdes.
So while commit 3d71746c42 ("PCI: armada8k: Add support for gpio controlled
reset signal") enables PCIe on platforms that U-Boot does not touch the
reset line (like Clearfog GT-8K), it breaks PCIe (and boot) on the
Macchiatobin board.

commit 802b7c06ad ("ARM: cns3xxx: Convert PCI to use generic config
accessors") reimplemented cns3xxx_pci_read_config() using
pci_generic_config_read32(), which preserved the property of only doing
32-bit reads.
It also replaced cns3xxx_pci_write_config() with pci_generic_config_write(),
so it changed writes from always being 32 bits to being the actual size,
which works just fine.
Given that:
- The documentation does not mention that only 32 bit access is allowed.
- Writes are already executed using the actual size
- Extensive testing shows that 8b, 16b and 32b reads work as intended
Allow read access of any size by replacing pci_generic_config_read32()
with the pci_generic_config_read() accessors.

Originally, cns3xxx used its own functions for mapping, reading and
writing config registers.
Commit 802b7c06ad ("ARM: cns3xxx: Convert PCI to use generic config
accessors") removed the internal PCI config write function in favor of
the generic one:
cns3xxx_pci_write_config() --> pci_generic_config_write()
cns3xxx_pci_write_config() expected aligned addresses, being produced by
cns3xxx_pci_map_bus() while the generic one pci_generic_config_write()
actually expects the real address as both the function and hardware are
capable of byte-aligned writes.
This currently leads to pci_generic_config_write() writing to the wrong
registers.
For instance, upon ath9k module loading:
- driver ath9k gets loaded
- The driver wants to write value 0xA8 to register PCI_LATENCY_TIMER,
located at 0x0D
- cns3xxx_pci_map_bus() aligns the address to 0x0C
- pci_generic_config_write() effectively writes 0xA8 into register 0x0C
(CACHE_LINE_SIZE)
Fix the bug by removing the alignment in the cns3xxx mapping function.

A deadlock has been seen when swicthing clocksources which use

change_clocksource

...
rpm_resume
pm_runtime_mark_last_busy
ktime_get

Although we should be safe because we haven't yet changed the
clocksource at that time, we can't do that because of seqcount
protection.
Use ktime_get_mono_fast_ns() instead which is lock safe for such
cases.
With ktime_get_mono_fast_ns, the timestamp is not guaranteed to be
monotonic across an update and as a result can goes backward.
According to update_fast_timekeeper() description: "In the worst
case, this can result is a slightly wrong timestamp (a few
nanoseconds)". For PM-runtime autosuspend, this means only that
the suspend decision may be slightly suboptimal.

The current dentry number tracking code doesn't distinguish between
positive & negative dentries. It just reports the total number of
dentries in the LRU lists.
As excessive number of negative dentries can have an impact on system
performance, it will be wise to track the number of positive and
negative dentries separately.
This patch adds tracking for the total number of negative dentries in
the system LRU lists and reports it in the 5th field in the
/proc/sys/fs/dentry-state file. The number, however, does not include
negative dentries that are in flight but not in the LRU yet as well as
those in the shrinker lists which are on the way out anyway.
The number of positive dentries in the LRU lists can be roughly found by
subtracting the number of negative dentries from the unused count.
Matthew Wilcox had confirmed that since the introduction of the
dentry_stat structure in 2.1.60, the dummy array was there, probably for
future extension. They were not replacements of pre-existing fields.
So no sane applications that read the value of /proc/sys/fs/dentry-state
will do dummy thing if the last 2 fields of the sysctl parameter are not
zero. IOW, it will be safe to use one of the dummy array entry for
negative dentry count.

The list_lru structure is essentially just a pointer to a table of
per-node LRU lists. Even if CONFIG_MEMCG_KMEM is defined, the list
field is just used for LRU list registration and shrinker_id is set at
initialization. Those fields won't need to be touched that often.
So there is no point to make the list_lru structures to sit in their own

The nr_dentry_unused per-cpu counter tracks dentries in both the LRU
lists and the shrink lists where the DCACHE_LRU_LIST bit is set.
The shrink_dcache_sb() function moves dentries from the LRU list to a
shrink list and subtracts the dentry count from nr_dentry_unused. This
is incorrect as the nr_dentry_unused count will also be decremented in
shrink_dentry_list() via d_shrink_del().
To fix this double decrement, the decrement in the shrink_dcache_sb()
function is taken out.

The interrupt handler contains a workaround for RX hang applicable
to Zynq and AT91RM9200 only. Subsequent versions do not need this
workaround. This workaround unnecessarily resets RX whenever RX used
bit read is observed, which can be often under heavy traffic. There
is no other action performed on RX UBR interrupt. Hence introduce a

Fix hp_pin always no value.
[More notes on the changes:
The hp_pin value that is referred in alc294_hp_init() is always zero
at the moment the function gets called, hence this is actually
useless as in the current code.
And, this kind of init sequence should be called from the codec init
callback, instead of the parser function. So, the first fix in this
patch to move the call call into its own init_hook.
OTOH, this function is needed to be called only once after the boot,
and it'd take too long for invoking at each resume (where the init
callback gets called). So we add a new flag and invoke this only
once as an additional fix.
The one case is still not covered, though: S4 resume. But this
change itself won't lead to any regression in that regard, so we
leave S4 issue as is for now and fix it later. -- tiwai ]

If there are outstanding async tx requests (when crypto returns EINPROGRESS),
there is a potential deadlock: the tx work acquires the lock, while we
cancel_delayed_work_sync() while holding the lock. Drop the lock while waiting
for the work to complete.

aead_request_set_crypt takes an iv pointer, and we change the iv
soon after setting it. Some async crypto algorithms don't save the iv,
so we need to save it in the tls_rec for async requests.
Found by hardcoding x64 aesni to use async crypto manager (to test the async
codepath), however I don't think this combination can happen in the wild.
Presumably other hardware offloads will need this fix, but there have been
no user reports.

After batched used ring updating was introduced in commit e2b3b35eb9
("vhost_net: batch used ring update in rx"). We tend to batch heads in
vq->heads for more than one packet. But the quota passed to
get_rx_bufs() was not correctly limited, which can result a OOB write
in vq->heads.
headcount = get_rx_bufs(vq, vq->heads + nvq->done_idx,
vhost_len, &in, vq_log, &log,
likely(mergeable) ? UIO_MAXIOV : 1);
UIO_MAXIOV was still used which is wrong since we could have batched
used in vq->heads, this will cause OOB if the next buffer needs more
than 960 (1024 (UIO_MAXIOV) - 64 (VHOST_NET_BATCH)) heads after we've
batched 64 (VHOST_NET_BATCH) heads:

Fixing this by allocating UIO_MAXIOV + VHOST_NET_BATCH iovs for
vhost-net. This is done through set the limitation through
vhost_dev_init(), then set_owner can allocate the number of iov in a
per device manner.
This fixes CVE-2018-16880.

Cache number of fragments in the skb locally as in case
of linear skb (with zero fragments), tx completion
(or freeing of skb) may happen before driver tries
to get number of frgaments from the skb which could
lead to stale access to an already freed skb.

VFs may hit VF-PF channel timeout while probing, as in some
cases it was observed that VF FLR and VF "acquire" message
transaction (i.e first message from VF to PF in VF's probe flow)
could occur simultaneously which could lead VF to fail sending
"acquire" message to PF as VF is marked disabled from HW perspective
due to FLR, which will result into channel timeout and VF probe failure.
In such cases, try retrying VF "acquire" message so that in later
attempts it could be successful to pass message to PF after the VF
FLR is completed and can be probed successfully.
