Pull ARM SoC DT and driver fixes from Arnd Bergmann:
"Lots of dts fixes for Qualcomm Snapdragon and NXP i.MX platforms,
including:
- A regression fix for SDHCI controllers on Inforce 6540, and another
SDHCI fix on SM8350
- Reenable cluster idle on sm8250 after the the code fix is upstream
- multiple fixes for the QMP PHY binding, needing an incompatible dt
change
- The reserved memory map is updated on Xiaomi Mi 4C and Huawei Nexus
6P, to avoid instabilities caused by use of protected memory
regions
- Fix i.MX8MP DT for missing GPC Interrupt, power-domain typo and USB
clock error
- A couple of verdin-imx8mm DT fixes for audio playback support
- Fix pca9547 i2c-mux node name for i.MX and Vybrid device trees
- Fix an imx93-11x11-evk uSDHC pad setting problem that causes Micron
eMMC CMD8 CRC error in HS400ES/HS400 mode
The remaining ARM and RISC-V platforms only have very few smaller dts
bugfixes this time:
- A fix for the SiFive unmatched board's PCI memory space
- A revert to fix a regression with GPIO on Marvell Armada
- A fix for the UART address on Marvell AC5
- Missing chip-select phandles for stm32 boards
- Selecting the correct clock for the sam9x60 memory controller
- Amlogic based Odroid-HC4 needs a revert to restore USB
functionality.
And finally, there are some minor code fixes:
- Build fixes for OMAP1, pxa, riscpc, raspberry pi firmware, and zynq
firmware
- memory controller driver fixes for an OMAP regression and older
bugs on tegra, atmel and mvebu
- reset controller fixes for ti-sci and uniphier platforms
- ARM SCMI firmware fixes for a couple of rare corner cases
- Qualcomm platform driver fixes for incorrect error handling and a
backwards compatibility fix for the apr driver using older dtb
- NXP i.MX SoC driver fixes for HDMI output, error handling in the
imx8 soc-id and missing reference counting on older cpuid code"

tcp: fix rate_app_limited to default to 1
The initial default value of 0 for tp->rate_app_limited was incorrect,
since a flow is indeed application-limited until it first sends
data. Fixing the default to be 1 is generally correct but also
specifically will help user-space applications avoid using the initial
tcpi_delivery_rate value of 0 that persists until the connection has
some non-zero bandwidth sample.

net: stmmac: enable all safety features by default
In the original implementation of dwmac5
commit
8bf993a5877e ("net: stmmac: Add support for DWMAC5 and implement Safety Features")
all safety features were enabled by default.
Later it seems some implementations didn't have support for all the
features, so in
commit
5ac712dcdfef ("net: stmmac: enable platform specific safety features")
the safety_feat_cfg structure was added to the callback and defined for
some platforms to selectively enable these safety features.
The problem is that only certain platforms were given that software
support. If the automotive safety package bit is set in the hardware
features register the safety feature callback is called for the platform,
and for platforms that didn't get a safety_feat_cfg defined this results
in the following NULL pointer dereference:

The existing self-tests depend on such error code, and the change

Of course, we can shuffle the get/put_cpu() to only wrap the invocation
of ->aura_freeptr() as what commit

two ->aura_freeptr() callbacks, otx2_aura_freeptr() and
cn10k_aura_freeptr(). There is no usage of perpcu variable in the
otx2_aura_freeptr() at all, so the get/put_cpu() seems redundant to it.
We can move the get/put_cpu() into the corresponding callback which
really has the percpu variable usage and avoid the sprinkling of
get/put_cpu() in several places.

tcp: avoid the lookup process failing to get sk in ehash table
While one cpu is working on looking up the right socket from ehash
table, another cpu is done deleting the request socket and is about
to add (or is adding) the big socket from the table. It means that
we could miss both of them, even though it has little chance.
Let me draw a call trace map of the server side.
CPU 0 CPU 1
----- -----
tcp_v4_rcv() syn_recv_sock()
inet_ehash_insert()
-> sk_nulls_del_node_init_rcu(osk)
__inet_lookup_established()
-> __sk_nulls_add_node_rcu(sk, list)
Notice that the CPU 0 is receiving the data after the final ack
during 3-way shakehands and CPU 1 is still handling the final ack.
Why could this be a real problem?
This case is happening only when the final ack and the first data
receiving by different CPUs. Then the server receiving data with
ACK flag tries to search one proper established socket from ehash
table, but apparently it fails as my map shows above. After that,
the server fetches a listener socket and then sends a RST because
it finds a ACK flag in the skb (data), which obeys RST definition
in RFC 793.
Besides, Eric pointed out there's one more race condition where it
handles tw socket hashdance. Only by adding to the tail of the list
before deleting the old one can we avoid the race if the reader has
already begun the bucket traversal and it would possibly miss the head.
Many thanks to Eric for great help from beginning to end.

Currently IFF_NO_ADDRCONF is used to prevent all ipv6 addrconf for the
slave ports of team, bonding and failover devices and it means no ipv6
packets can be sent out through these slave ports. However, for team
device, "nsna_ping" link_watch requires ipv6 addrconf. Otherwise, the

drm/amd/display: fix issues with driver unload
Currently, we run into a number of WARN()s when attempting to unload the
amdgpu driver (e.g. using "modprobe -r amdgpu"). These all stem from
calling drm_encoder_cleanup() too early. So, to fix this we can stop
calling drm_encoder_cleanup() from amdgpu_dm_fini() and instead have it
be called from amdgpu_dm_encoder_destroy(). Also, we don't need to free
in amdgpu_dm_encoder_destroy() since mst_encoders[] isn't explicitly
allocated by the slab allocator.

The YCC conversion matrix for RGB -> COLOR_SPACE_YCBCR2020_TYPE is

added given that the color is 3 components in size.

This issue was introduced by commit

protects code paths from being executed on uninitialized devices.
In the case of vga-switcheroo, we want to allow a switch away from

test in the switcheroo callbacks if the i915 device is available.

virtio-net: correctly enable callback during start_xmit
Commit
a7766ef18b33("virtio_net: disable cb aggressively") enables

virtqueue_disable_cb(sq->vq);
free_old_xmit_skbs(sq, false);
} while (use_napi && kick &&

When NAPI is used and kick is false, the callback won't be enabled
here. And when the virtqueue is about to be full, the tx will be
disabled, but we still don't enable tx interrupt which will cause a TX
hang. This could be observed when using pktgen with burst enabled.
TO be consistent with the logic that tries to disable cb only for
NAPI, fixing this by trying to enable delayed callback only when NAPI
is enabled when the queue is about to be full.

net: macb: fix PTP TX timestamp failure due to packet padding
PTP TX timestamp handling was observed to be broken with this driver
when using the raw Layer 2 PTP encapsulation. ptp4l was not receiving
the expected TX timestamp after transmitting a packet, causing it to
enter a failure state.
The problem appears to be due to the way that the driver pads packets
which are smaller than the Ethernet minimum of 60 bytes. If headroom
space was available in the SKB, this caused the driver to move the data
back to utilize it. However, this appears to cause other data references
in the SKB to become inconsistent. In particular, this caused the
ptp_one_step_sync function to later (in the TX completion path) falsely
detect the packet as a one-step SYNC packet, even when it was not, which
caused the TX timestamp to not be processed when it should be.
Using the headroom for this purpose seems like an unnecessary complexity
as this is not a hot path in the driver, and in most cases it appears
that there is sufficient tailroom to not require using the headroom
anyway. Remove this usage of headroom to prevent this inconsistency from
occurring and causing other problems.

The option "--buildid-dir" sets the build id cache directory as
/tmp/perf.debug.TeY1. The option given to buildid-cahe, ie "-a
./tests/shell/../pe-file.exe", is to add the pe-file.exe to the cache.
The testcase, sets buildid-dir and adds the file: pe-file.exe to build
id cache. To check if the command is run successfully, "check" function
looks for presence of the file in buildid cache directory. But the check
here expects the added file to be executable. Snippet below:

The buildid test is done for sha1 binary, md5 binary and also for PE
file. The first two binaries are created at runtime by compiling with
"--build-id" option and hence the check for sha1/md5 test should use [ !
-x ]. But in case of PE file, the permission for this input file is
rw-r--r-- Hence the file added to build id cache has same permissoin

just check for existence of the buildid file using [ ! -e <file> ]

build id cache operations: FAILED!
The failing test is when trying to add pe-file.exe to build id cache.
'perf buildid-cache' can be used to add/remove/manage files from the
build-id cache. "-a" option is used to add a file to the build-id cache.
Simple command to do so for a PE exe file:
# ls -ltr tests/pe-file.exe
-rw-r--r--. 1 root root 75595 Jan 10 23:35 tests/pe-file.exe
The file is in home directory.
# mkdir /tmp/perf.debug.TeY1
# perf --buildid-dir /tmp/perf.debug.TeY1 buildid-cache -v -a tests/pe-file.exe
The above will create ".build-id" folder in build id directory, which is
/tmp/perf.debug.TeY1. Also adds file to this folder under build id.
Example:
# ls -ltr /tmp/perf.debug.TeY1/.build-id/5a/
0fd882b53084224ba47b624c55a469/
total 76
-rw-r--r--. 1 root root 0 Jan 11 00:38 probes
-rwxr-xr-x. 1 root root 75595 Jan 11 00:38 elf
We can see in the results that file mode for original file and file in
build id directory is different. ie, build id file has executable
permission whereas original file doesn’t have.
The code path and function (build_id_cache__add to add a file to the
cache is in "util/build-id.c". In build_id_cache__add() function, it
first attempts to link the original file to destination cache folder.
If linking the file fails (which can happen if the destination and
source is on a different mount points), it will copy the file to
destination. Here copyfile() routine explicitly uses mode as "755" and
hence file in the destination will have executable permission.
Code snippet:
if (link(realname, filename) && errno != EEXIST && copyfile(name, filename))
strace logs:
172285 link("/home/<user_name>/linux/tools/perf/tests/pe-file.exe", "/tmp/perf.debug.TeY1/home/<user_name>/linux/tools/perf/tests/pe-file.exe/
5a0fd882b53084224ba47b624c55a469/elf") = -1 EXDEV (Invalid cross-device link)
172285 newfstatat(AT_FDCWD, "tests/pe-file.exe", {st_mode=S_IFREG|0644, st_size=75595, ...}, 0) = 0
172285 openat(AT_FDCWD, "/tmp/perf.debug.TeY1/home/<user_name>/linux/tools/perf/tests/pe-file.exe/
5a0fd882b53084224ba47b624c55a469/.elf.KbAnsl", O_RDWR|O_CREAT|O_EXCL, 0600) = 3
172285 fchmod(3, 0755) = 0
172285 openat(AT_FDCWD, "tests/pe-file.exe", O_RDONLY) = 4
172285 mmap(NULL, 75595, PROT_READ, MAP_PRIVATE, 4, 0) = 0x7fffa5cd0000
172285 pwrite64(3, "MZ\220\0\3\0\0\0\4\0\0\0\377\377\0\0\270\0\0\0\0\0\0\0@\0\0\0\0\0\0\0"..., 75595, 0) = 75595
Whereas if the link succeeds, it succeeds in the first attempt itself
and the file in the build-id dir will have same permission as original
file.
Example, above uses /tmp. Instead if we use "--buildid-dir /home/build",
linking will work here since mount points are same. Hence the
destination file will not have executable permission.
Since the testcase "tests/shell/buildid.sh" always looks for executable
file, test fails in powerpc environment when test is run from /root.
The patch adds a change in build_id_cache__add() to use copyfile_mode()
which also passes the file’s original mode as argument. This way the
destination file mode also will be same as original file.
