Wonhyuk Yang c70c3b6e62 mm/compaction: fix misbehaviors of fast_find_migrateblock()
[ Upstream commit 15d28d0d11609c7a4f217b3d85e26456d9beb134 ]

In the fast_find_migrateblock(), it iterates ocer the freelist to find the
proper pageblock.  But there are some misbehaviors.

First, if the page we found is equal to cc->migrate_pfn, it is considered
that we didn't find a suitable pageblock.  Secondly, if the loop was
terminated because order is less than PAGE_ALLOC_COSTLY_ORDER, it could be
considered that we found a suitable one.  Thirdly, if the skip bit is set
on the page block and we goto continue, it doesn't check nr_scanned.
Fourthly, if the page block's skip bit is set, it checks that page block
is the last of list, which is unnecessary.

Miaohe Lin c200f49595 mm/hugetlb: fix potential double free in hugetlb_register_node() error path
[ Upstream commit cc2205a67dec5a700227a693fc113441e73e4641 ]

In hugetlb_sysfs_add_hstate(), we would do kobject_put() on hstate_kobjs
when failed to create sysfs group but forget to set hstate_kobjs to NULL.
Then in hugetlb_register_node() error path, we may free it again via
hugetlb_unregister_node().

Miaohe Lin 67a982ee20 mm/memory.c: fix potential pte_unmap_unlock pte error
[ Upstream commit 90a3e375d324b2255b83e3dd29e99e2b05d82aaf ]

Since commit 42e4089c78 ("x86/speculation/l1tf: Disallow non privileged
high MMIO PROT_NONE mappings"), when the first pfn modify is not allowed,
we would break the loop with pte unchanged.  Then the wrong pte - 1 would
be passed to pte_unmap_unlock.

Andi said:

 "While the fix is correct, I'm not sure if it actually is a real bug.
  Is there any architecture that would do something else than unlocking
  the underlying page? If it's just the underlying page then it should
  be always the same page, so no bug"

Taehee Yoo 55b6be947e vxlan: move debug check after netdev unregister
[ Upstream commit 92584ddf550ae72d492858c19d1f9025e07a9350 ]

The debug check must be done after unregister_netdevice_many() call --

    ip netns del A
    ip netns add A
    ip netns add B

Slawomir Laba d7c25783b8 i40e: Fix flow for IPv6 next header (extension header)
[ Upstream commit 92c6058024e87087cf1b99b0389d67c0a886360e ]

When a packet contains an IPv6 header with next header which is
an extension header and not a protocol one, the kernel function
skb_transport_header called with such sk_buff will return a
pointer to the extension header and not to the TCP one.

The above explained call caused a problem with packet processing
for skb with encapsulation for tunnel with I40E_TX_CTX_EXT_IP_IPV6.
The extension header was not skipped at all.

The ipv6_skip_exthdr function does check if next header of the IPV6
header is an extension header and doesn't modify the l4_proto pointer
if it points to a protocol header value so its safe to omit the
comparison of exthdr and l4.hdr pointers. The ipv6_skip_exthdr can
return value -1. This means that the skipping process failed
and there is something wrong with the packet so it will be dropped.

[ Upstream commit d288a5712ef961e16d588bbdb2d846e00b5ef154 ]

sdw_update_slave_status will be invoked when a codec is attached,
and the codec driver will initialize the codec with regmap functions
while the codec device is pm_runtime suspended.

regmap routines currently rely on regular SoundWire IO functions,
which will call pm_runtime_get_sync()/put_autosuspend.

This causes a deadlock where the resume routine waits for an
initialization complete signal that while the initialization complete
can only be reached when the resume completes.

The only solution if we allow regmap functions to be used in resume
operations as well as during codec initialization is to use _no_pm
routines. The duty of making sure the bus is operational needs to be
handled above the regmap level.

Ahmad Fatoum 62c4532ebb nvmem: core: skip child nodes not matching binding
[ Upstream commit 0445efacec75b85c2a3c176957ee050ba9be53f0 ]

The nvmem cell binding applies to all eeprom child nodes matching
"^.*@[0-9a-f]+$" without taking a compatible into account.

Linux drivers, like at24, are even more extensive and assume
_all_ at24 eeprom child nodes to be nvmem cells since e888d445ac
("nvmem: resolve cells from DT at registration time").

Since df5f3b6f5357 ("dt-bindings: nvmem: stm32: new property for
data access"), the additionalProperties: True means it's Ok to have
other properties as long as they don't match "^.*@[0-9a-f]+$".

The barebox bootloader extends the MTD partitions binding to
EEPROM and can fix up following device tree node:

  &eeprom {
    partitions {
      compatible = "fixed-partitions";
    };
  };

This is allowed binding-wise, but drivers using nvmem_register()
like at24 will fail to parse because the function expects all child
nodes to have a reg property present. This results in the whole
EEPROM driver probe failing despite the device tree being correct.

Fix this by skipping nodes lacking a reg property instead of
returning an error. This effectively makes the drivers adhere
to the binding because all nodes with a unit address must have
a reg property and vice versa.

Theodore Ts'o d8b7689a62 ext4: fix potential htree index checksum corruption
[ Upstream commit b5776e7524afbd4569978ff790864755c438bba7 ]

In the case where we need to do an interior node split, and
immediately afterwards, we are unable to allocate a new directory leaf
block due to ENOSPC, the directory index checksum's will not be filled
in correctly (and indeed, will not be correctly journalled).

This looks like a bug that was introduced when we added largedir
support.  The original code doesn't make any sense (and should have

[ Upstream commit 4a19f37a3dd3f29997735e61b25ddad24b8abe73 ]

vfio_sanity_check_pfn_list() is used to check whether pfn_list and
notifier are empty when remove the external domain, so it makes a
wrong assumption that only external domain will use the pinning
interface.

Now we apply the pfn_list check when a vfio_dma is removed and apply
the notifier check when all domains are removed.

[ Upstream commit 68e4f01fddb4ead80e8c7084db489307f22c9cbb ]

Before the offending commit in msm_atomic_commit_tail wait_flush was
called once per frame, after the commit was submitted. After it
wait_flush is also called at the beginning to ensure previous
potentially async commits are done.

For cmd panels the source of wait_flush is a ping-pong irq notifying
a completion. The completion needs to be notified with complete_all so
multiple waiting parties (new async committers) can proceed.

After 34e3207205 ("PCI: handle positive error codes"),
pci_user_read_config_*() and pci_user_write_config_*() return 0 or negative
errno values, not PCIBIOS_* values like PCIBIOS_SUCCESSFUL or
PCIBIOS_BAD_REGISTER_NUMBER.

Remove comparisons with PCIBIOS_SUCCESSFUL and check only for non-zero.  It
happens that PCIBIOS_SUCCESSFUL is zero, so this is not a functional
change, but it aligns this code with the user accessors.

[ Upstream commit d5d8d675865ccddfe4da26c85f22c55cec663bf2 ]

If rockchip_pwm_probe() fails to register a PWM device it calls
clk_unprepare() for the device's PWM clock, without having first disabled
the clock and before jumping to an error handler that also unprepares
it. This is likely to produce warnings from the kernel about the clock
being unprepared when it is still enabled, and then being unprepared when
it has already been unprepared.

Prevent these warnings by removing this unnecessary call to
clk_unprepare().

The existing code reports a NAK only when ACK=0
This is not aligned with the SoundWire 1.x specifications.

Table 32 in the SoundWire 1.2 specification shows that a Device shall
not set NAK=1 if ACK=1. But Table 33 shows the Combined Response
may very well be NAK=1/ACK=1, e.g. if another Device than the one
addressed reports a parity error.

NAK=1 signals a 'Command_Aborted', regardless of the ACK bit value.

detected according to the specification.

[ Upstream commit 429fa9698957d1a910535ce5e33aedf5adfdabc1 ]

The size of tx_valid_cpus was calculated under the assumption that the
numa nodes identifiers are continuous, which is not the case in all archs
as this could lead to the following panic when trying to access an invalid
tx_valid_cpus index, avoid the following panic by using nr_node_ids
instead of num_online_nodes() to allocate the tx_valid_cpus size.

AngeloGioacchino Del Regno c42d1e8caa clk: qcom: gcc-msm8998: Fix Alpha PLL type for all GPLLs
[ Upstream commit 292f75ecff07e8a07fe2e3e19b4b567d0b698842 ]

All of the GPLLs in the MSM8998 Global Clock Controller are Fabia PLLs
and not generic alphas: this was producing bad effects over the entire
clock tree of MSM8998, where any GPLL child clock was declaring a false
clock rate, due to their parent also showing the same.

The issue resides in the calculation of the clock rate for the specific
Alpha PLL type, where Fabia has a different register layout; switching
the MSM8998 GPLLs to the correct Alpha Fabia PLL type fixes the rate
(calculation) reading. While at it, also make these PLLs fixed since
their rate is supposed to *never* be changed while the system runs, as
this would surely crash the entire SoC.

Now all the children of all the PLLs are also complying with their
specified clock table and system stability is improved.

Nathan Lynch ba5c8a0ee6 powerpc/pseries/dlpar: handle ibm, configure-connector delay status
[ Upstream commit 768d70e19ba525debd571b36e6d0ab19956c63d7 ]

dlpar_configure_connector() has two problems in its handling of
ibm,configure-connector's return status:

1. When the status is -2 (busy, call again), we call
   ibm,configure-connector again immediately without checking whether
   to schedule, which can result in monopolizing the CPU.
2. Extended delay status (9900..9905) goes completely unhandled,
   causing the configuration to unnecessarily terminate.

Fix both of these issues by using rtas_busy_delay().

The "req" struct is always added to the "wm831x->auxadc_pending" list,
but it's only removed from the list on the success path.  If a failure
occurs then the "req" struct is freed but it's still on the list,
leading to a use after free.

[ Upstream commit 5120bf0a5fc15dec210a0fe0f39e4a256bb6e349 ]

rxe_net.c sends packets at the IP layer with skb->data pointing at the IP
header but receives packets from a UDP tunnel with skb->data pointing at
the UDP header.  On the loopback path this was not correctly accounted
for.  This patch corrects for this by using sbk_pull() to strip the IP
header from the skb on received packets.

[ Upstream commit 8fc1b7027fc162738d5a85c82410e501a371a404 ]

rxe_rcv_mcast_pkt() in rxe_recv.c can leak SKBs in error path code. The
loop over the QPs attached to a multicast group creates new cloned SKBs
for all but the last QP in the list and passes the SKB and its clones to
rxe_rcv_pkt() for further processing. Any QPs that do not pass some checks
are skipped.  If the last QP in the list fails the tests the SKB is
leaked.  This patch checks if the SKB for the last QP was used and if not
frees it. Also removes a redundant loop invariant assignment.
