[ Upstream commit e3fce68cdbed297d927e993b3ea7b8b1cee545da ]
Currently dax_iomap_rw() takes care of invalidating page tables and
evicting hole pages from the radix tree when write(2) to the file
happens. This invalidation is only necessary when there is some block
allocation resulting from write(2). Furthermore in current place the
invalidation is racy wrt page fault instantiating a hole page just after
we have invalidated it.
So perform the page invalidation inside dax_iomap_actor() where we can
do it only when really necessary and after blocks have been allocated so
nobody will be instantiating new hole pages anymore.

[ Upstream commit 61b6034c6cfdcb265bb453505c3d688e7567727a ]
is_power_of_2 expects unsigned long and we pass u64 max_val_cycles,
this will be truncated on 32 bit systems, and the result is not what we
were expecting.
div_u64 expects u32 as a second argument and we pass
max_val_cycles_rounded which is u64 hence it will always be truncated.
Fix was tested on both 64 and 32 bit systems and got same results for
max_val_cycles and max_val_cycles_rounded.

[ Upstream commit a9b2dff80be979432484afaf7f8d8e73f9e8838a ]
For connected sockets, __l2tp_ip{,6}_bind_lookup() needs to check the
remote IP when looking for a matching socket. Otherwise a connected
socket can receive traffic not originating from its peer.
Drop l2tp_ip_bind_lookup() and l2tp_ip6_bind_lookup() instead of
updating their prototype, as these functions aren't used.

The first message to a remote node should prompt a new
connection even if it is RDMA operation. For RDMA operation
the MR mapping can fail because connections is not yet up.
Since the connection establishment is asynchronous,
we make sure the map failure because of unavailable
connection reach to the user by appropriate error code.
Before returning to the user, lets trigger the connection
so that its ready for the next retry.

chan->desc is always set to NULL when a DMA transfer is complete.
As a DMA transfer could be complete during the call of stm32_dma_tx_status,
we need to be sure that chan->desc is not NULL before using this variable
to avoid a null pointer deference issue.

As the SPDIF was rarely documented on the earlier Allwinner SoCs
it was assumed that it had a similar clock register to the one
described in the H3 User Manual.
However this is not the case and it looks to shares the same setup
as the I2S clock registers.

If 'sun4i_backend_drm_format_to_layer()' does not return 0, then 'val' is
left unmodified.
As it is not initialized either, the return value can be anything.
It is likely that returning the error code was expected here.
As the only caller of 'sun4i_backend_update_layer_formats()' does not check
the return value, this fix is purely theorical.

From: Bjorn Helgaas <bhelgaas@google.com>
[ Upstream commit 977509f7c5c6fb992ffcdf4291051af343b91645 ]
Previously we didn't check the type of device before trying to apply Type 1
(PCI-X) or Type 2 (PCIe) Setting Records from _HPX.
We don't support PCI-X Setting Records, so this was harmless, but the
warning was useless.
We do support PCIe Setting Records, and we didn't check whether a device
was PCIe before applying settings. I don't think anything bad happened on
non-PCIe devices because pcie_capability_clear_and_set_word(),
pcie_cap_has_lnkctl(), etc., would fail before doing any harm. But it's
ugly to depend on those internals.
Check the device type before attempting to apply Type 1 and Type 2 Setting
Records (Type 0 records are applicable to PCI, PCI-X, and PCIe devices).
A side benefit is that this prevents useless "not supported" warnings when
a BIOS supplies a Type 1 (PCI-X) Setting Record and we try to apply it to
every single device:
pci 0000:00:00.0: PCI-X settings not supported
After this patch, we'll get the warning only when a BIOS supplies a Type 1
record and we have a PCI-X device to which it should be applied.

[ Upstream commit fc318d64f3d91e15babac00e08354b1beb650b57 ]
The zx_dma driver supports cyclic transfer mode. Let's set DMA_CYCLIC
cap_mask bit to make that clear, and avoid unnecessary failure when
clients request channel via dma_request_chan_by_mask() with DMA_CYCLIC
bit set in mask.

[ Upstream commit 38e5a85562a6cd911fc26d951d576551a688574c ]
Inserting the TSB means adding an extra 8 bytes in front the of packet
that is going to be used as metadata information by the TDMA engine, but
stripped off, so it does not really help with the packet padding.
For some odd packet sizes that fall below the 60 bytes payload (e.g: ARP)
we can end-up padding them after the TSB insertion, thus making them 64
bytes, but with the TDMA stripping off the first 8 bytes, they could
still be smaller than 64 bytes which is required to ingress the switch.
Fix this by swapping the padding and TSB insertion, guaranteeing that
the packets have the right sizes.

OMAP1510, OMAP5910 and OMAP310 have only 9 logical channels.
OMAP1610, OMAP5912, OMAP1710, OMAP730, and OMAP850 have 16 logical channels
available.
The wired 17 for the lch_count must have been used to cover the 16 + 1
dedicated LCD channel, in reality we can only use 9 or 16 channels.
The d->chan_count is not used by the omap-dma stack, so we can skip the
setup. chan_count was configured to the number of logical channels and not
the actual number of physical channels anyways.

[ Upstream commit 54475f531bb8d7078f63c159e5e0615d486c498c ]
As part of an effort to clean up fscrypt-related error codes, make
attempting to create a file in an encrypted directory that hasn't been
"unlocked" fail with ENOKEY. Previously, several error codes were used
for this case, including ENOENT, EACCES, and EPERM, and they were not
consistent between and within filesystems. ENOKEY is a better choice
because it expresses that the failure is due to lacking the encryption
key. It also matches the error code returned when trying to open an
encrypted regular file without the key.
I am not aware of any users who might be relying on the previous
inconsistent error codes, which were never documented anywhere.
This failure case will be exercised by an xfstest.

vti6 interface is registered before the rtnl_link_ops block
is attached. As a result the resulting RTM_NEWLINK is missing
IFLA_INFO_KIND. Re-order attachment of rtnl_link_ops block to fix.

From: David Ahern <dsa@cumulusnetworks.com>
[ Upstream commit 7bb387c5ab12aeac3d5eea28686489ff46b53ca9 ]
IP_MULTICAST_IF fails if sk_bound_dev_if is already set and the new index
does not match it. e.g.,
ntpd[15381]: setsockopt IP_MULTICAST_IF 192.168.1.23 fails: Invalid argument
Relax the check in setsockopt to allow setting mc_index to an L3 slave if
sk_bound_dev_if points to an L3 master.
Make a similar change for IPv6. In this case change the device lookup to
take the rcu_read_lock avoiding a refcnt. The rcu lock is also needed for
the lookup of a potential L3 master device.
This really only silences a setsockopt failure since uses of mc_index are
secondary to sk_bound_dev_if if it is set. In both cases, if either index
is an L3 slave or master, lookups are directed to the same FIB table so
relaxing the check at setsockopt time causes no harm.
Patch is based on a suggested change by Darwin for a problem noted in
their code base.

Commit 988d44b "be2net: Avoid redundant addition of mac address in HW"
introduced be_dev_mac_add & be_uc_mac_add helpers that incorrectly
access adapter->uc_list as an array of bytes instead of an array of
be_eth_addr. Consequently NIC is not filled with valid data so unicast
filtering is broken.

[ Upstream commit dffd0cfa06d4ed83bb3ae8eb067989ceec5d18e1 ]
As part of an effort to clean up fscrypt-related error codes, make
FS_IOC_SET_ENCRYPTION_POLICY fail with ENOTDIR when the file descriptor
does not refer to a directory. This is more descriptive than EINVAL,
which was ambiguous with some of the other error cases.
I am not aware of any users who might be relying on the previous error
code of EINVAL, which was never documented anywhere, and in some buggy
kernels did not exist at all as the S_ISDIR() check was missing.
This failure case will be exercised by an xfstest.
