[ Upstream commit c8ea23d5fa59f28302d4e3370c75d9c308e64410 ]
This device is a CF card, or possibly an SSD in CF form factor.
It supports NCQ and high speed DMA.
While it also advertises TRIM support, I/O errors are reported
when the discard mount option fstrim is used. TRIM also fails
when disabling NCQ and not just as an NCQ command.
TRIM must be disabled for this device.

commit f8efca92ae509c25e0a4bd5d0a86decea4f0c41e upstream.
Do alignment logic properly and use the "ptr" local variable for
calculating the remainder of the alignment.
This became an issue because struct edac_mc_layer has a size that is not
zero modulo eight, and the next offset that was prepared for the private
data was unaligned, causing an alignment exception.
The patch in Fixes: which broke this actually wanted to "what we
actually care about is the alignment of the actual pointer that's about
to be returned." But it didn't check that alignment.
Use the correct variable "ptr" for that.

[ Upstream commit e5ce576d45bf72fd0e3dc37eff897bfcc488f6a9 ]
Upon error the ieee802154_xmit_complete() helper is not called. Only
ieee802154_wake_queue() is called manually. In the Tx case we then leak
the skb structure.
Free the skb structure upon error before returning when appropriate.
As the 'is_tx = 0' cannot be moved in the complete handler because of a
possible race between the delay in switching to STATE_RX_AACK_ON and a
new interrupt, we introduce an intermediate 'was_tx' boolean just for
this purpose.
There is no Fixes tag applying here, many changes have been made on this
area and the issue kind of always existed.

CONFIG_PCI is not set
and hence PCI_LBA is not set.
IOSAPIC depends on PCI_LBA, so IOSAPIC is not set/enabled.

commit 57bc3d3ae8c14df3ceb4e17d26ddf9eeab304581 upstream.
ax88179_rx_fixup() contains several out-of-bounds accesses that can be
triggered by a malicious (or defective) USB device, in particular:
- The metadata array (hdr_off..hdr_off+2*pkt_cnt) can be out of bounds,
causing OOB reads and (on big-endian systems) OOB endianness flips.
- A packet can overlap the metadata array, causing a later OOB
endianness flip to corrupt data used by a cloned SKB that has already
been handed off into the network stack.
- A packet SKB can be constructed whose tail is far beyond its end,
causing out-of-bounds heap data to be considered part of the SKB's
data.
I have tested that this can be used by a malicious USB device to send a
bogus ICMPv6 Echo Request and receive an ICMPv6 Echo Reply in response
that contains random kernel heap data.
It's probably also possible to get OOB writes from this on a
little-endian system somehow - maybe by triggering skb_cow() via IP
options processing -, but I haven't tested that.

commit c0d79987a0d82671bff374c07f2201f9bdf4aaa2 upstream.
When setting the fan speed, i8k_set_fan() calls i8k_get_fan_status(),
causing an unnecessary SMM call since from the two users of this
function, only i8k_ioctl_unlocked() needs to know the new fan status
while dell_smm_write() ignores the new fan status.
Since SMM calls can be very slow while also making error reporting
difficult for dell_smm_write(), remove the function call from
i8k_set_fan() and call it separately in i8k_ioctl_unlocked().
Tested on a Dell Inspiron 3505.

With CPU re-ordering on write instructions, there might
be a chance that the HWO is set before the TRB is updated
with the new mapped buffer address.
And in the case where core is processing a list of TRBs
it is possible that it fetched the TRBs when the HWO is set
but before the buffer address is updated.
Prevent this by adding a memory barrier before the HWO
is updated to ensure that the core always process the
updated TRBs.

$ man poll

POLLRDNORM
Equivalent to POLLIN.
However, in n_tty driver, POLLRDNORM does not return until timeout even
if there is terminal input, whereas POLLIN returns.
The following test program works until kernel-3.17, but the test stops
in poll() after commit 57087d515441 ("tty: Fix spurious poll() wakeups").
[Steps to run test program]
$ cc -o test-pollrdnorm test-pollrdnorm.c
$ ./test-pollrdnorm
foo <-- Type in something from the terminal followed by [RET].

When 803.2ad mode enables a participating port, it should update
the slave-array. I have observed that the member links are participating
and are part of the active aggregator while the traffic is egressing via
only one member link (in a case where two links are participating). Via
kprobes I discovered that slave-arr has only one link added while
the other participating link wasn't part of the slave-arr.
I couldn't see what caused that situation but the simple code-walk
through provided me hints that the enable_port wasn't always associated
with the slave-array update.

However, its backported version in 4.9 (commit 9f1a3c13342b ("net:

instructions in `axienet_dma_bd_init` instead.
Unlike upstream, the version of `__axienet_device_reset` currently present
in branch stable/linux-4.9.y does not return an integer for error codes.
Therefore fixing the backport cannot be as simple as moving the inserted
instructions in the right place, and we simply revert it instead.

commit 279eb8575fdaa92c314a54c0d583c65e26229107 upstream.
The driver overrides the error codes returned by platform_get_irq() to
-ENODEV for some strange reason, so if it returns -EPROBE_DEFER, the
driver will fail the probe permanently instead of the deferred probing.
Switch to propagating the proper error codes to platform driver code
upwards.

commit d0cfa548dbde354de986911d3913897b5448faad upstream.
When setting Tx sci explicit, the Rx side is expected to use this
sci and not recalculate it from the packet.However, in case of Tx sci
is explicit and send_sci is off, the receiver is wrongly recalculate
the sci from the source MAC address which most likely be different
than the explicit sci.
Fix by preventing such configuration when macsec newlink is established
and return EINVAL error code on such cases.

commit 9b45a7738eec52bf0f5d8d3d54e822962781c5f2 upstream.
The polling loop for the register change in iommu_ga_log_enable() needs
to have a udelay() in it. Otherwise the CPU might be faster than the
IOMMU hardware and wrongly trigger the WARN_ON() further down the code
stream. Use a 10us for udelay(), has there is some hardware where
activation of the GA log can take more than a 100ms.
A future optimization should move the activation check of the GA log
to the point where it gets used for the first time. But that is a
bigger change and not suitable for a fix.

Bounds checking when parsing init scripts embedded in the BIOS reject
access to the last byte. This causes driver initialization to fail on
Apple eMac's with GeForce 2 MX GPUs, leaving the system with no working
console.
This is probably only seen on OpenFirmware machines like PowerPC Macs
because the BIOS image provided by OF is only the used parts of the ROM,
not a power-of-two blocks read from PCI directly so PCs always have
empty bytes at the end that are never accessed.

[ Upstream commit a66c5ed539277b9f2363bbace0dba88b85b36c26 ]
According to its datasheet, G781 supports a maximum conversion rate value
of 8 (62.5 ms). However, chips labeled G781 and G780 were found to only
support a maximum conversion rate value of 7 (125 ms). On the other side,
chips labeled G781-1 and G784 were found to support a conversion rate value
of 8. There is no known means to distinguish G780 from G781 or G784; all
chips report the same manufacturer ID and chip revision.
Setting the conversion rate register value to 8 on chips not supporting
it causes unexpected behavior since the real conversion rate is set to 0
(16 seconds) if a value of 8 is written into the conversion rate register.
Limit the conversion rate register value to 7 for all G78x chips to avoid
the problem.

commit 26fbe9772b8c459687930511444ce443011f86bf upstream.
The syzbot fuzzer has identified a bug in which processes hang waiting
for usb_kill_urb() to return. It turns out the issue is not unlinking
the URB; that works just fine. Rather, the problem arises when the
wakeup notification that the URB has completed is not received.
The reason is memory-access ordering on SMP systems. In outline form,
usb_kill_urb() and __usb_hcd_giveback_urb() operating concurrently on
different CPUs perform the following actions:
CPU 0 CPU 1
---------------------------- ---------------------------------
usb_kill_urb(): __usb_hcd_giveback_urb():
... ...
atomic_inc(&urb->reject); atomic_dec(&urb->use_count);
... ...
wait_event(usb_kill_urb_queue,
atomic_read(&urb->use_count) == 0);
if (atomic_read(&urb->reject))
wake_up(&usb_kill_urb_queue);
Confining your attention to urb->reject and urb->use_count, you can
see that the overall pattern of accesses on CPU 0 is:
write urb->reject, then read urb->use_count;
whereas the overall pattern of accesses on CPU 1 is:
write urb->use_count, then read urb->reject.
This pattern is referred to in memory-model circles as SB (for "Store
Buffering"), and it is well known that without suitable enforcement of
the desired order of accesses -- in the form of memory barriers -- it
is entirely possible for one or both CPUs to execute their reads ahead
of their writes. The end result will be that sometimes CPU 0 sees the
old un-decremented value of urb->use_count while CPU 1 sees the old
un-incremented value of urb->reject. Consequently CPU 0 ends up on
the wait queue and never gets woken up, leading to the observed hang
in usb_kill_urb().
The same pattern of accesses occurs in usb_poison_urb() and the
failure pathway of usb_hcd_submit_urb().
The problem is fixed by adding suitable memory barriers. To provide
proper memory-access ordering in the SB pattern, a full barrier is
required on both CPUs. The atomic_inc() and atomic_dec() accesses
themselves don't provide any memory ordering, but since they are
present, we can use the optimized smp_mb__after_atomic() memory
barrier in the various routines to obtain the desired effect.
This patch adds the necessary memory barriers.

commit 5b67b315037250a61861119683e7fcb509deea25 upstream.
Two people have reported (and mentioned numerous other reports on the
web) that VIA's VL817 USB-SATA bridge does not work with the uas
driver. Typical log messages are:
[ 3606.232149] sd 14:0:0:0: [sdg] tag#2 uas_zap_pending 0 uas-tag 1 inflight: CMD
[ 3606.232154] sd 14:0:0:0: [sdg] tag#2 CDB: Write(16) 8a 00 00 00 00 00 18 0c c9 80 00 00 00 80 00 00
[ 3606.306257] usb 4-4.4: reset SuperSpeed Plus Gen 2x1 USB device number 11 using xhci_hcd
[ 3606.328584] scsi host14: uas_eh_device_reset_handler success
Surprisingly, the devices do seem to work okay for some other people.
The cause of the differing behaviors is not known.
In the hope of getting the devices to work for the most users, even at
the possible cost of degraded performance for some, this patch adds an
unusual_devs entry for the VL817 to block it from binding to the uas
driver by default. Users will be able to override this entry by means
of a module parameter, if they want.
