e5fa173f9a Here's the last batch of clk driver fixes for this release. These
patches fix serious problems, for example, i.MX has an issue where
 changing the NAND clk frequency hangs the system. On Allwinner H6 the
 GPU is being overclocked which could lead to long term hardware damage.
 And finally on some Broadcom SoCs the serial console stopped working
 because the clk tree hierarchy description got broken by an inadvertant
 DT node name change. That's fixed by using 'clock-output-names' to
 generate a stable and unique name for clks so the framework can properly
 link things up.
 
 There's also a couple build fixes in here. One to fix CONFIG_OF=n builds
 and one to avoid an array out of bounds bug that happens during clk
 registration on microchip. I hope that KASAN would have found that OOB
 problem, but probably KASAN wasn't attempted. Instead LLVM/clang
 compilation caused an oops, while GCC didn't.

c816f2e981 perf tools fixes for v6.0: 5th batch
- Fail the 'perf test record' entry on error, fixing a regression where just
   setup stuff like allocating memory and not the actual things being tested failed.
 
 - Fixup disabling of -Wdeprecated-declarations for the python scripting engine, the
   previous attempt had a brown paper bag thinko.
 
 - Fix branch stack sampling test to include sanity check for branch filter on PowerPC.
 
 - Update is_ignored_symbol function to match the kernel ignored list, fixing running
   the 'perf test' entry that compares resolving symbols from kallsyms to resolving from
   vmlinux.
 
 - Augment the data source type with ARM's neoverse_spe list, the previous code
   was limited in its search resolving the data source.
 
 - Fix some clang 5 variable set but unused cases.
 
 - Get a perf cgroup more portably in BPF as the __builtin_preserve_enum_value builtin is
   not available in older versions of clang. In those cases we can forgo BPF's CO-RE (Compile
   Once, Run Everywhere).
 
 - More Fixes for Intel's hybrid CPU model.

920541bb0b A small fix to the reported set of supported CPUID bits, and selftests fixes:
* Skip tests that require EPT when it is not available
 
 * Do not hang when a test fails with an empty stack trace
 
 * avoid spurious failure when running access_tracking_perf_test in a KVM guest
 
 * work around GCC's tendency to optimize loops into mem*() functions, which
   breaks because the guest code in selftests cannot call into PLTs

40158dbf7e Revert "pstore: migrate to crypto acomp interface"
This reverts commit e4f0a7ec58.

When using this new interface, both efi_pstore and ramoops
backends are unable to properly decompress dmesg if using
zstd, lz4 and lzo algorithms (and maybe more). It does succeed
with deflate though.

The message observed in the kernel log is:

[2.328828] pstore: crypto_acomp_decompress failed, ret = -22!

The pstore infrastructure is able to collect the dmesg with
both backends tested, but since decompression fails it's
unreadable. With this revert everything is back to normal.

394265079b KVM: selftests: Compare insn opcodes directly in fix_hypercall_test
Directly compare the expected versus observed hypercall instructions when
verifying that KVM patched in the native hypercall (FIX_HYPERCALL_INSN
quirk enabled).  gcc rightly complains that doing a 4-byte memcpy() with
an "unsigned char" as the source generates an out-of-bounds accesses.

Alternatively, "exp" and "obs" could be declared as 3-byte arrays, but
there's no known reason to copy locally instead of comparing directly.

6b6f71484b KVM: selftests: Implement memcmp(), memcpy(), and memset() for guest use
Implement memcmp(), memcpy(), and memset() to override the compiler's
built-in versions in order to guarantee that the compiler won't generate
out-of-line calls to external functions via the PLT.  This allows the
helpers to be safely used in guest code, as KVM selftests don't support
dynamic loading of guest code.

Steal the implementations from the kernel's generic versions, sans the
optimizations in memcmp() for unaligned accesses.

Put the utilities in a separate compilation unit and build with
-ffreestanding to fudge around a gcc "feature" where it will optimize
memset(), memcpy(), etc... by generating a recursive call.  I.e. the
compiler optimizes itself into infinite recursion.  Alternatively, the
individual functions could be tagged with
optimize("no-tree-loop-distribute-patterns"), but using "optimize" for
anything but debug is discouraged, and Linus NAK'd the use of the flag
in the kernel proper[*].

09636efd1b KVM: selftests: Gracefully handle empty stack traces
Bail out of test_dump_stack() if the stack trace is empty rather than
invoking addr2line with zero addresses. The problem with the latter is
that addr2line will block waiting for addresses to be passed in via
stdin, e.g. if running a selftest from an interactive terminal.

Opportunistically fix up the comment that mentions skipping 3 frames
since only 2 are skipped in the code.

6336a810db KVM: selftests: replace assertion with warning in access_tracking_perf_test
Page_idle uses {ptep/pmdp}_clear_young_notify which in turn calls
the mmu notifier callback ->clear_young(), which purposefully
does not flush the TLB.

When running the test in a nested guest, point 1. of the test
doc header is violated, because KVM TLB is unbounded by size
and since no flush is forced, KVM does not update the sptes
accessed/idle bits resulting in guest assertion failure.

More precisely, only the first ACCESS_WRITE in run_test() actually
makes visible changes, because sptes are created and the accessed
bit is set to 1 (or idle bit is 0). Then the first mark_memory_idle()
passes since access bit is still one, and sets all pages as idle
(or not accessed). When the next write is performed, the update
is not flushed therefore idle is still 1 and next mark_memory_idle()
fails.

83ca5fb40e drm/amd/display: Prevent OTG shutdown during PSR SU
[Why]

Enabling Z10 optimizations allows DMUB to disable the OTG during PSR
link-off. This theoretically saves power by putting more of the display
hardware to sleep. However, we observe that with PSR SU, it causes
visual artifacts, higher power usage, and potential system hang.

This is partly due to an odd behavior with the VStartup interrupt used
to signal DRM vblank events. If the OTG is toggled on/off during a PSR
link on/off cycle, the vstartup interrupt fires twice in quick
succession. This generates incorrectly timed vblank events.
Additionally, it can cause cursor updates to generate visual artifacts.

Note that this is not observed with PSR1 since PSR is fully disabled
when there are vblank event requestors. Cursor updates are also
artifact-free, likely because there are no selectively-updated (SU)
frames that can generate artifacts.

[How]

A potential solution is to disable z10 idle optimizations only when fast
updates (flips & cursor updates) are committed. A mechanism to do so
would require some thoughtful design. Let's just disable idle
optimizations for PSR2 for now.

25c5e67cdf perf tests record: Fail the test if the 'errs' counter is not zero
We were just checking for the 'err' variable, when we should really see
if there was some of the many checked errors that don't stop the test
right away.

Detected with clang 15.0.0:

  44    75.23 fedora:37       : FAIL clang version 15.0.0 (Fedora 15.0.0-2.fc37)

                          ^
    1 error generated.

The patch introducing this 'perf test' entry had that check:

  +       return (err < 0 || errs > 0) ? -1 : 0;

But at some point we lost that:

  -	  return (err < 0 || errs > 0) ? -1 : 0;
  +	  if (err == -EACCES)
  +               return TEST_SKIP;
  +	  if (err < 0)
  +               return TEST_FAIL;
  +	  return TEST_OK

Put it back.

30e51b923e mptcp: fix unreleased socket in accept queue
The mptcp socket and its subflow sockets in accept queue can't be
released after the process exit.

While the release of a mptcp socket in listening state, the
corresponding tcp socket will be released too. Meanwhile, the tcp
socket in the unaccept queue will be released too. However, only init
subflow is in the unaccept queue, and the joined subflow is not in the
unaccept queue, which makes the joined subflow won't be released, and
therefore the corresponding unaccepted mptcp socket will not be released
to.

This can be reproduced easily with following steps:

1. create 2 namespace and veth:
   $ ip netns add mptcp-client
   $ ip netns add mptcp-server
   $ sysctl -w net.ipv4.conf.all.rp_filter=0
   $ ip netns exec mptcp-client sysctl -w net.mptcp.enabled=1
   $ ip netns exec mptcp-server sysctl -w net.mptcp.enabled=1
   $ ip link add red-client netns mptcp-client type veth peer red-server \
     netns mptcp-server
   $ ip -n mptcp-server address add 10.0.0.1/24 dev red-server
   $ ip -n mptcp-server address add 192.168.0.1/24 dev red-server
   $ ip -n mptcp-client address add 10.0.0.2/24 dev red-client
   $ ip -n mptcp-client address add 192.168.0.2/24 dev red-client
   $ ip -n mptcp-server link set red-server up
   $ ip -n mptcp-client link set red-client up

2. configure the endpoint and limit for client and server:
   $ ip -n mptcp-server mptcp endpoint flush
   $ ip -n mptcp-server mptcp limits set subflow 2 add_addr_accepted 2
   $ ip -n mptcp-client mptcp endpoint flush
   $ ip -n mptcp-client mptcp limits set subflow 2 add_addr_accepted 2
   $ ip -n mptcp-client mptcp endpoint add 192.168.0.2 dev red-client id \
     1 subflow

3. listen and accept on a port, such as 9999. The nc command we used
   here is modified, which makes it use mptcp protocol by default.
   $ ip netns exec mptcp-server nc -l -k -p 9999

4. open another *two* terminal and use each of them to connect to the
   server with the following command:
   $ ip netns exec mptcp-client nc 10.0.0.1 9999
   Input something after connect to trigger the connection of the second
   subflow. So that there are two established mptcp connections, with the
   second one still unaccepted.

5. exit all the nc command, and check the tcp socket in server namespace.
   And you will find that there is one tcp socket in CLOSE_WAIT state
   and can't release forever.

Fix this by closing all of the unaccepted mptcp socket in
mptcp_subflow_queue_clean() with __mptcp_close().

Now, we can ensure that all unaccepted mptcp sockets will be cleaned by
__mptcp_close() before they are released, so mptcp_sock_destruct(), which
is used to clean the unaccepted mptcp socket, is not needed anymore.

The selftests for mptcp is ran for this commit, and no new failures.

First patch allows user space to see done descriptor in CQ even after a

I also forgot to mention that due to the current Tx cleaning algorithm,
4k HW ring was broken and these two patches bring it back to life, so we

276d37eb44 net: mscc: ocelot: fix tagged VLAN refusal while under a VLAN-unaware bridge
Currently the following set of commands fails:

$ ip link add br0 type bridge # vlan_filtering 0
$ ip link set swp0 master br0
$ bridge vlan
port              vlan-id
swp0              1 PVID Egress Untagged
$ bridge vlan add dev swp0 vid 10
Error: mscc_ocelot_switch_lib: Port with more than one egress-untagged VLAN cannot have egress-tagged VLANs.

Dumping ocelot->vlans, one can see that the 2 egress-untagged VLANs on swp0 are
vid 1 (the bridge PVID) and vid 4094, a PVID used privately by the driver for
VLAN-unaware bridging. So this is why bridge vid 10 is refused, despite
'bridge vlan' showing a single egress untagged VLAN.

As mentioned in the comment added, having this private VLAN does not impose
restrictions to the hardware configuration, yet it is a bookkeeping problem.

There are 2 possible solutions.

One is to make the functions that operate on VLAN-unaware pvids:
- ocelot_add_vlan_unaware_pvid()
- ocelot_del_vlan_unaware_pvid()
- ocelot_port_setup_dsa_8021q_cpu()
- ocelot_port_teardown_dsa_8021q_cpu()
call something different than ocelot_vlan_member_(add|del)(), the latter being
the real problem, because it allocates a struct ocelot_bridge_vlan *vlan which
it adds to ocelot->vlans. We don't really *need* the private VLANs in
ocelot->vlans, it's just that we have the extra convenience of having the
vlan->portmask cached in software (whereas without these structures, we'd have
to create a raw ocelot_vlant_rmw_mask() procedure which reads back the current
port mask from hardware).

The other solution is to filter out the private VLANs from
ocelot_port_num_untagged_vlans(), since they aren't what callers care about.
We only need to do this to the mentioned function and not to
ocelot_port_num_tagged_vlans(), because private VLANs are never egress-tagged.

Nothing else seems to be broken in either solution, but the first one requires
more rework which will conflict with the net-next change  36a0bf4435 ("net:

1b24a132eb clk: iproc: Do not rely on node name for correct PLL setup
After commit 31fd9b79dc ("ARM: dts: BCM5301X: update CRU block
description") a warning from clk-iproc-pll.c was generated due to a
duplicate PLL name as well as the console stopped working. Upon closer
inspection it became clear that iproc_pll_clk_setup() used the Device
Tree node unit name as an unique identifier as well as a parent name to
parent all clocks under the PLL.

BCM5301X was the first platform on which that got noticed because of the
DT node unit name renaming but the same assumptions hold true for any
user of the iproc_pll_clk_setup() function.

The first 'clock-output-names' property is always guaranteed to be
unique as well as providing the actual desired PLL clock name, so we
utilize that to register the PLL and as a parent name of all children
clock.

4014e916fd clk: sunxi-ng: h6: Fix default PLL GPU rate
In commit 4167ac8a65 ("clk: sunxi-ng: sun50i: h6: Modify GPU clock
configuration to support DFS") divider M0 was forced to be 1 in order to
support DFS. However, that left N as it is, at high value of 36. On
boards without devfreq enabled (all of them in kernel 6.0), this
effectively sets GPU frequency to 864 MHz. This is about 100 MHz above
maximum supported frequency.

In order to fix this, let's set N to 18 (register value 17). That way
default frequency of 432 MHz is preserved.

should not be used. For instance, the default parent clock for QSPI is
pll2_bus, which is also the parent clock for quite a few modules, such
as MMDC, once GPMI NAND set clock rate for EDO5 mode can cause system

06bbaa6dc5 [coredump] don't use __kernel_write() on kmap_local_page()
passing kmap_local_page() result to __kernel_write() is unsafe -
random ->write_iter() might (and 9p one does) get unhappy when
passed ITER_KVEC with pointer that came from kmap_local_page().

Fix by providing a variant of __kernel_write() that takes an iov_iter
from caller (__kernel_write() becomes a trivial wrapper) and adding
dump_emit_page() that parallels dump_emit(), except that instead of
__kernel_write() it uses __kernel_write_iter() with ITER_BVEC source.
