Similar to
https://lore.kernel.org/bpf/20210313210920.1959628-2-andrii@kernel.org/
When DECLARE_LIBBPF_OPTS is used with inline field initialization, e.g:
DECLARE_LIBBPF_OPTS(btf_dump_emit_type_decl_opts, opts,
.field_name = var_ident,
.indent_level = 2,
.strip_mods = strip_mods,
);
and compiled in debug mode, the compiler generates code which
leaves the padding uninitialized and triggers errors within libbpf APIs
which require strict zero initialization of OPTS structs.
Adding anonymous padding field fixes the issue.

The ECN bit defines ECT(1) = 1, ECT(0) = 2. So inner 0x02 + outer 0x01
should be inner ECT(0) + outer ECT(1). Based on the description of
__INET_ECN_decapsulate, the final decapsulate value should be
ECT(1). So fix the test expect value to 0x01.
Before the fix:
TEST: VXLAN: ECN decap: 01/02->0x02 [FAIL]
Expected to capture 10 packets, got 0.
After the fix:
TEST: VXLAN: ECN decap: 01/02->0x01 [ OK ]

For AF_VSOCK, accept() currently returns sockets that are unlabelled.
Other socket families derive the child's SID from the SID of the parent
and the SID of the incoming packet. This is typically done as the
connected socket is placed in the queue that accept() removes from.
Reuse the existing 'security_sk_clone' hook to copy the SID from the
parent (server) socket to the child. There is no packet SID in this
case.

MTU cannot be changed on dwmac-sun8i. (ip link set eth0 mtu xxx returning EINVAL)
This is due to tx_fifo_size being 0, since this value is used to compute valid
MTU range.
Like dwmac-sunxi (with commit 806fd188ce2a ("net: stmmac: dwmac-sunxi: Provide TX and RX fifo sizes"))
dwmac-sun8i need to have tx and rx fifo sizes set.
I have used values from datasheets.
After this patch, setting a non-default MTU (like 1000) value works and network is still useable.

net: ipa: update configuration data
Each IPA version has a "data" file defining how various things are
configured. This series gathers a few updates to this information:
- The first patch makes all configuration data constant
- The second fixes an incorrect (but seemingly harmless) value
- The third simplifies things a bit by using implicit zero
initialization for memory regions that are empty
- The fourth adds definitions for memory regions that exist but
are not yet used
- The fifth use configuration data rather than conditional code to
set some bus parameters

There are several memory regions that are defined starting with IPA
v4.0, but which were not used for the SC7180 SoC (IPA v4.2). Even
though they're not used (yet), define them so they are ready to be
used for SoCs when they become supported.
There are two QUOTA statistics memory regions, one for the modem and
one for the AP. Define distinct names for these regions, and get

The AP_HEADER memory region for both the SDM845 and SC7180 SoCs has
zero size, and has no canaries. Defining an offset for such a
zero-length region is not meaningful, so it's better not to define
it at all. The size of this region is used in the code, but its
value will still be zero because the memory regions are defined in
statically initialized memory.
For the SC7180, the STATS_DROP memory region has a zero size and no
canaries as well.
These regions are the only place where a zero-sized region is
defined despite having no canaries. Remove them.

There should be no canary values written before the beginning of the

If the USB host controller is EHCI, the throughput is reduced from
300Mb/s to 60Mb/s, when the rx buffer size is modified from 16K to
32K.
According to the EHCI spec, the maximum size of the qTD is 20K.
Therefore, when the driver uses more than 20K buffer, the latency
time of EHCI would be increased. And, it let the RTL8153A get worse
throughput.
However, the driver uses alloc_pages() for rx buffer, so I limit
the rx buffer to 16K rather than 20K.

Here is what Vladimir says about it:
at803x_aneg_done() keeps the aneg reporting as "not done" even when
the copper-side link was reported as up, but the in-band autoneg has
not finished.
That was the _intended_ behavior when that code was introduced, and
Heiner have said about it [1]:
| That's not nice from the PHY:
| It signals "link up", and if the system asks the PHY for link details,
| then it sheepishly says "well, link is *almost* up".
If the specification of phy_aneg_done behavior does not include
in-band autoneg (and it doesn't), then this piece of code does not
belong here.
The fact that we can no longer trigger this code from phylib is yet
another reason why it fails at its intended (and wrong) purpose and
should be removed.
Removing the SGMII link check, would just keep the call to
genphy_aneg_done(), which is also the fallback. Thus we can just remove
at803x_aneg_done() altogether.

The sk's sk_route_caps is set in sctp_packet_config, and later it
only needs to change when traversing the transport_list in a loop,
as the dst might be changed in the tx path.
So move sk_route_caps check and set into sctp_outq_flush_transports
from sctp_packet_transmit. This also fixes a dst leak reported by
Chen Yi:
https://bugzilla.kernel.org/show_bug.cgi?id=212227
As calling sk_setup_caps() in sctp_packet_transmit may also set the
sk_route_caps for the ctrl sock in a netns. When the netns is being
deleted, the ctrl sock's releasing is later than dst dev's deleting,
which will cause this dev's deleting to hang and dmesg error occurs:

When using short intervals e.g. below one millisecond, large packets won't be
transmitted at all. The software implementations checks whether the packet can
be fit into the remaining interval. Therefore, it takes the packet length and
the transmission speed into account. That is correct.
However, for large packets it may be that the transmission time exceeds the
interval resulting in no packet transmission. The same situation works fine with
hardware offloading applied.
The problem has been observed with the following schedule and iperf3:
|tc qdisc replace dev lan1 parent root handle 100 taprio \
| num_tc 8 \
| map 0 1 2 3 4 5 6 7 0 1 2 3 4 5 6 7 \

After debugging, it seems that the packet length stored in the SKB is about
7000-8000 bytes. Using a 100 Mbit/s link the transmission time is about 600us
which larger than the interval of 500us.
Therefore, segment the SKB into smaller chunks if the packet is too big. This
yields similar results than the hardware offload:

Furthermore, the segmentation can be skipped for the full offload case, as the
driver or the hardware is expected to handle this.

Pull workqueue tracing fix from Steven Rostedt:
"Fix workqueue trace event unsafe string reference
After adding a verifier to test all strings printed in trace events to
make sure they either point to a string on the ring buffer, or to read
only core kernel memory, it triggered on a workqueue trace event. The
trace event workqueue_queue_work references the allocated name of the
workqueue in the output. If the workqueue is freed before the trace is
read, then the trace will dereference freed memory.
Update the trace event to use the __string(), __assign_str(), and
__get_str() helpers to handle such cases"

- Revert ACPI PM commit that attempted to improve reboot handling on
some systems, but it caused other systems to panic() during reboot

- Revert PM-runtime commit that attempted to improve the handling of
suppliers during PM-runtime suspend of a consumer device, but it

Applications that create and extend and write to a file do not
expect to see 0 allocation size. When file is extended,
set its allocation size to a plausible value until we have a
chance to query the server for it. When the file is cached
this will prevent showing an impossible number of allocated
blocks (like 0). This fixes e.g. xfstests 614 which does
1) create a file and set its size to 64K
2) mmap write 64K to the file
3) stat -c %b for the file (to query the number of allocated blocks)
It was failing because we returned 0 blocks. Even though we would
return the correct cached file size, we returned an impossible
allocation size.

Add a couple of checks to make sure timestamping is on and that the
timestamp value from DMA is valid. This avoids any functional issues
that could come from a misinterpreted time stamp.
One of the functions changed doesn't need a return value added because
there was no value in checking from the calling locations.
While here, fix a couple of reverse christmas tree issues next to
the code being changed.

The include guard "_E1000_HW_H_" is used by two separate header files in
two different drivers (e1000/e1000_hw.h and igb/e1000_hw.h). Using the
same include guard macro in more than one header file may cause
unexpected behavior from the compiler. Fix this by renaming the
duplicate guard in the igb driver.
