Now that we are passing a struct ext4_filename, we do not need to pass
around the original struct qstr too.

The 'lend' argument of filemap_write_and_wait_range() is inclusive, so
we need to subtract 1 from pos + count.
Note that 'count' is guaranteed to be nonzero since
ext4_file_read_iter() returns early when given a 0 count.

ext4_find_unwritten_pgoff() is used to search for offset of hole or
data in page range [index, end] (both inclusive), and the max number
of pages to search should be at least one, if end == index.
Otherwise the only page is missed and no hole or data is found,
which is not correct.
When block size is smaller than page size, this can be demonstrated
by preallocating a file with size smaller than page size and writing
data to the last block. E.g. run this xfs_io command on a 1k block
size ext4 on x86_64 host.
# xfs_io -fc "falloc 0 3k" -c "pwrite 2k 1k" \
-c "seek -d 0" /mnt/ext4/testfile
wrote 1024/1024 bytes at offset 2048
1 KiB, 1 ops; 0.0000 sec (42.459 MiB/sec and 43478.2609 ops/sec)
Whence Result
DATA EOF
Data at offset 2k was missed, and lseek(2) returned ENXIO.
This is unconvered by generic/285 subtest 07 and 08 on ppc64 host,
where pagesize is 64k. Because a recent change to generic/285
reduced the preallocated file size to smaller than 64k.

get_reg() can be reentered on architectures with prioritized interrupts
(m68k in this case), causing f->reg_index to be incremented after the
range check. Out of bounds memory access past the pt_regs struct results.
This will go mostly undetected unless access is beyond end of memory.
Prevent the race by disabling interrupts in get_reg().
Tested on m68k (Atari Falcon, and ARAnyM emulator).
Kudos to Geert Uytterhoeven for helping to trace this race.

We end up reading the interrupt register for HPD5, and then writing it
to HPD6 which on systems without anything using HPD5 results in
permanently disabling hotplug on one of the display outputs after the
first time we acknowledge a hotplug interrupt from the GPU.
This code is really bad. But for now, let's just fix this. I will
hopefully have a large patch series to refactor all of this soon.

At least some of the be2net cards do not seem to be capabled
of performing checksum offload computions on Q-in-Q packets.
In these case, the recevied checksum on the remote is invalid
and TCP syn packets are dropped.
This patch adds a call to check disbled acceleration features
on Q-in-Q tagged traffic.

It appears that TCP checksum offloading has been broken for
Q-in-Q vlans. The behavior was execerbated by the
series
commit afb0bc972b52 ("Merge branch 'stacked_vlan_tso'")
that that enabled accleleration features on stacked vlans.
However, event without that series, it is possible to trigger
this issue. It just requires a lot more specialized configuration.
The root cause is the interaction between how
netdev_intersect_features() works, the features actually set on
the vlan devices and HW having the ability to run checksum with
longer headers.
The issue starts when netdev_interesect_features() replaces
NETIF_F_HW_CSUM with a combination of NETIF_F_IP_CSUM | NETIF_F_IPV6_CSUM,
if the HW advertises IP|IPV6 specific checksums. This happens
for tagged and multi-tagged packets. However, HW that enables
IP|IPV6 checksum offloading doesn't gurantee that packets with
arbitrarily long headers can be checksummed.
This patch disables IP|IPV6 checksums on the packet for multi-tagged
packets.

rtnl_fdb_dump() failed to check the result of nlmsg_parse(), which led
to contents of |ifm| being uninitialized because nlh->nlmsglen was too
small to accommodate |ifm|. The uninitialized data may affect some
branches and result in unwanted effects, although kernel data doesn't
seem to leak to the userspace directly.
The bug has been detected with KMSAN and syzkaller.

sctp: a bunch of fixes for processing dupcookie
After introducing transport hashtable and per stream info into sctp,
some regressions were caused when processing dupcookie, this patchset
is to fix them.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

After sctp changed to use transport hashtable, a transport would be
added into global hashtable when adding the peer to an asoc, then
the asoc can be got by searching the transport in the hashtbale.
The problem is when processing dupcookie in sctp_sf_do_5_2_4_dupcook,
a new asoc would be created. A peer with the same addr and port as
the one in the old asoc might be added into the new asoc, but fail
to be added into the hashtable, as they also belong to the same sk.
It causes that sctp's dupcookie processing can not really work.
Since the new asoc will be freed after copying it's information to
the old asoc, it's more like a temp asoc. So this patch is to fix
it by setting it as a temp asoc to avoid adding it's any transport
into the hashtable and also avoid allocing assoc_id.
An extra thing it has to do is to also alloc stream info for any
temp asoc, as sctp dupcookie process needs it to update old asoc.
But I don't think it would hurt something, as a temp asoc would
always be freed after finishing processing cookie echo packet.

Since commit 3dbcc105d556 ("sctp: alloc stream info when initializing
asoc"), stream and stream.out info are always alloced when creating
an asoc.
So it's not correct to check !asoc->stream before updating stream
info when processing dupcookie, but would be better to check asoc
state instead.

When pci_enable_device() or pci_enable_device_mem() fail in
qla2x00_probe_one() we bail out but do a call to
pci_disable_device(). This causes the dev_WARN_ON() in
pci_disable_device() to trigger, as the device wasn't enabled
previously.
So instead of taking the 'probe_out' error path we can directly return
*iff* one of the pci_enable_device() calls fails.
Additionally rename the 'probe_out' goto label's name to the more
descriptive 'disable_device'.

ALSA SoC needs to know connected DAI ID for probing.
It is not a big problem if device/driver was only for sound,
but getting DAI ID will be difficult if device includes both
Video/Sound, like HDMI.
To solve this issue, this patch adds new .get_dai_id callback
on hdmi_codec_ops

DesignWare HDMI driver (= dw-hdmi) is supporting HDMI sound, and its
probe function was calling sound binding function multiple times as
same HDMI device different port.
Because of this behavior, commit 9731f82d601 ("ASoC: hdmi-codec: enable
multi probe for ...") was added for multi detection case.
But, this DesignWare HDMI detection/bind code was exchanged/adjusted by
commit 69497eb9234 ("drm: bridge: dw-hdmi: Implement DRM bridge...").
Now, all DesignWare HDMI sound ports are detected as 1 bindng function.
Because of this, hdmi-codec multi detection support is no longer needed.
Thus, this patch removes
commit 9731f82d601 ("ASoC: hdmi-codec: enable multi probe for ..."),
and its related
commit 340327a62c4 ("ASoC: hdmi-codec: Fix hdmi_of_xlate_dai_name...")

It is not a big problem if device/driver was only for sound,
but getting DAI ID will be difficult if device includes both
Video/Sound, like HDMI.
To solve this issue, this patch adds new snd_soc_get_dai_id() and
its related .of_xlate_dai_id callback on component driver.
In below case, we can handle Sound port (= port@2) as ID = 0
if .of_xlate_dai_id has its support.
hdmi {
port@0 { /* VIDEO */ };
port@1 { /* VIDEO */ };
port@2 { /* SOUND */ };
};

In SKL+ platforms, all IPC commands are serialised, i.e. the driver sends
a new IPC to DSP, only after receiving a reply from the firmware for the
current IPC.
Hence it seems apparent that there is only a single modifier of the IPC RX
List. However, during an IPC timeout case in a multithreaded environment,
there is a possibility of the list element being deleted two times if not
properly protected.
So, use spin lock save/restore to prevent rx_list corruption.

soc_cleanup_card_resources() call snd_card_free() at the last of its
procedure. This turned out to lead to a use-after-free.
PCM runtimes have been already removed via soc_remove_pcm_runtimes(),
while it's dereferenced later in soc_pcm_free() called via
snd_card_free().
The fix is simple: just move the snd_card_free() call to the beginning
of the whole procedure. This also gives another benefit: it
guarantees that all operations have been shut down before actually
releasing the resources, which was racy until now.
