If CONFIG_QFMT_V2 is not enabled, but CONFIG_QUOTA is enabled, when a
user tries to mount a file system with the quota or project quota
enabled, the kernel will emit a very confusing messsage:
EXT4-fs warning (device vdc): ext4_enable_quotas:5914: Failed to enable quota tracking (type=0, err=-3). Please run e2fsck to fix.
EXT4-fs (vdc): mount failed
We will now report an explanatory message indicating which kernel
configuration options have to be enabled, to avoid customer/sysadmin
confusion.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

With ipip, it is possible to create an extra interface explicitly

# ip link add ip6tnl1 type ip6tnl dev eth0
RTNETLINK answers: File exists
This patch aims to make it possible by adding link comparaison in both
tunnel locate and lookup functions; we also modify mtu calculation when
attached to an interface with a lower mtu.
This permits to make use of x-netns communication by moving the newly
created tunnel in a given netns.

Johannes Berg says:
====================
Just a few fixes:
* avoid running out of tracking space for frames that need
to be reported to userspace by using more bits
* fix beacon handling suppression by adding some relevant
elements to the CRC calculation
* fix quiet mode in action frames
* fix crash in ethtool for virt_wifi and similar
* add a missing policy entry
* fix 160 & 80+80 bandwidth to take local capabilities into
account

SMC does not work together with FASTOPEN. If sendmsg() is called with
flag MSG_FASTOPEN in SMC_INIT state, the SMC-socket switches to
fallback mode. To handle the previous ioctl FIOASYNC call correctly
in this case, it is necessary to transfer the socket wait queue
fasync_list to the internal TCP socket.

net: hns3: fixes for -net
This series includes three bugfixes for the HNS3 ethernet driver.
[patch 1] fixes a management table lost issue after IMP reset.
[patch 2] fixes a VF bandwidth configuration not work problem.
[patch 3] fixes a problem related to IPv6 address copying.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
The IPv6 address defined in struct in6_addr is specified as
big endian, but there is no specified endian in struct
hclge_fd_rule_tuples, so it will cause a problem if directly
use memcpy() to copy ipv6 address between these two structures
since this field in struct hclge_fd_rule_tuples is little endian.
This patch fixes this problem by using be32_to_cpu() to convert
endian of IPv6 address of struct in6_addr before copying.

Longer description:
In llvm-utils.c we use some techniques to obtain the kbuild make
directives and that recently stopped working as now 'ar' gets called and
expects to find the dummy.o used to echo these variables:
$(NOSTDINC_FLAGS) $(LINUXINCLUDE) $(EXTRA_CFLAGS)
Add the $(CC) line to satisfy that, making sure this works with all
kernels, i.e. preserving the temp directory and files in it used for
this technique we can see that it works everywhere:
# make -s -C /lib/modules/5.4.18-100.fc30.x86_64/build M=/tmp/tmp.qgaFHgxjZ4/ clean
# ls -la /tmp/tmp.qgaFHgxjZ4/

#
# cat /tmp/tmp.qgaFHgxjZ4/Makefile
obj-y := dummy.o
$(obj)/%.o: $(src)/%.c
@echo -n "$(NOSTDINC_FLAGS) $(LINUXINCLUDE) $(EXTRA_CFLAGS)"
$(CC) -c -o $@ $<
#
Then build with an old kernel Makefile:

Before this patch, STA's would set new width of 160/80+80 MHz based on AP capability only.
This is wrong because STA may not support > 80MHz BW.
Fix is to verify STA has 160/80+80 MHz capability before increasing its width to > 80MHz.
The "support_80_80" and "support_160" setting is based on:
"Table 9-272 — Setting of the Supported Channel Width Set subfield and Extended NSS BW
Support subfield at a STA transmitting the VHT Capabilities Information field"

Merge tag 'drm-intel-next-fixes-2020-02-13' of git://anongit.freedesktop.org/drm/drm-intel into drm-fixes
drm/i915 fixes for v5.6-rc2
Most of these were aimed at a "next fixes" pull already during the merge
window, but there were issues with the baseline I used, which resulted
in a lot of issues in CI. I've regenerated this stuff piecemeal now,
adding gradually to it, and it seems healthy now.
Due to the issues this is much bigger than I'd like. But it was
obviously necessary to take the time to ensure it's not garbage...

Thus, there is no need to create a software top buttons row.
However, it seems that the device works under SMBus, so keep it as part

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

Carter reported an issue where he could produce a stall on ring exit,
when we're cleaning up requests that match the given file table. For
this particular test case, a combination of a few things caused the
issue:
- The cq ring was overflown
- The request being canceled was in the overflow list
The combination of the above means that the cq overflow list holds a
reference to the request. The request is canceled correctly, but since
the overflow list holds a reference to it, the final put won't happen.
Since the final put doesn't happen, the request remains in the inflight.
Hence we never finish the cancelation flush.
Fix this by removing requests from the overflow list if we're canceling
them.
