Reorder include paths to ensure that runqslower sources are picking up
vmlinux.h, generated by runqslower's own Makefile. When runqslower is built
from selftests/bpf, due to current -I$(BPF_INCLUDE) -I$(OUTPUT) ordering, it
might pick up not-yet-complete vmlinux.h, generated by selftests Makefile,
which could lead to compilation errors like [0]. So ensure that -I$(OUTPUT)
goes first and rely on runqslower's Makefile own dependency chain to ensure
vmlinux.h is properly completed before source code relying on it is compiled.

This adds a new selftest that tests the ability to attach an freplace
program to a program type that relies on the expected_attach_type of the
target program to pass verification.

For some program types, the verifier relies on the expected_attach_type of
the program being verified in the verification process. However, for
freplace programs, the attach type was not propagated along with the
verifier ops, so the expected_attach_type would always be zero for freplace
programs.
This in turn caused the verifier to sometimes make the wrong call for
freplace programs. For all existing uses of expected_attach_type for this
purpose, the result of this was only false negatives (i.e., freplace
functions would be rejected by the verifier even though they were valid
programs for the target they were replacing). However, should a false
positive be introduced, this can lead to out-of-bounds accesses and/or
crashes.
The fix introduced in this patch is to propagate the expected_attach_type
to the freplace program during verification, and reset it after that is
done.

The current JIT clobbers the destination register for BPF_JSET BPF_X
and BPF_K by using "and" and "or" instructions. This is fine when the
destination register is a temporary loaded from a register stored on
the stack but not otherwise.
This patch fixes the problem (for both BPF_K and BPF_X) by always loading
the destination register into temporaries since BPF_JSET should not
modify the destination register.
This bug may not be currently triggerable as BPF_REG_AX is the only
register not stored on the stack and the verifier uses it in a limited
way.

The current JIT uses the following sequence to zero-extend into the
upper 32 bits of the destination register for BPF_LDX BPF_{B,H,W},
when the destination register is not on the stack:
EMIT3(0xC7, add_1reg(0xC0, dst_hi), 0);
The problem is that C7 /0 encodes a MOV instruction that requires a 4-byte
immediate; the current code emits only 1 byte of the immediate. This
means that the first 3 bytes of the next instruction will be treated as
the rest of the immediate, breaking the stream of instructions.
This patch fixes the problem by instead emitting "xor dst_hi,dst_hi"
to clear the upper 32 bits. This fixes the problem and is more efficient
than using MOV to load a zero immediate.
This bug may not be currently triggerable as BPF_REG_AX is the only
register not stored on the stack and the verifier uses it in a limited
way, and the verifier implements a zero-extension optimization. But the
JIT should avoid emitting incorrect encodings regardless.

when an allocation fails, and the network interface needs to safely
handle this packet loss. Therefore, an allocation failure of Rx
SKBs is relatively benign.
However, the output of the warning message occurs with a high
scheduling priority that can cause excessive jitter/latency for
other high priority processing.
This commit suppresses the warning messages to prevent scheduling

When a macsec interface is created, the mtu is calculated with the lower
interface's mtu value.
If the mtu of lower interface is lower than the length, which is needed
by macsec interface, macsec's mtu value will be overflowed.
So, if the lower interface's mtu is too low, macsec interface's mtu
should be set to 0.

ip link add dummy0 mtu 10 type dummy
ip link add macsec0 link dummy0 type macsec
ip link show macsec0

The defaults listed in the bindings don't match what the code is
actually doing. Presumably existing users care more about keeping
existing behavior the same, so change the bindings to match the code
in Linux.
The "qcom,preemphasis-level" default has been wrong for quite a long
time (May 2018). The other two were recently added.
As some evidence that these values are wrong, this is from the Linux
driver:
- qcom,preemphasis-level: sets "PORT_TUNE1", lower 2 bits. Driver
programs PORT_TUNE1 to 0x30 by default and (0x30 & 0x3) = 0.
- qcom,bias-ctrl-value: sets "PLL_BIAS_CONTROL_2", lower 6 bits.
Driver programs PLL_BIAS_CONTROL_2 to 0x20 by default and (0x20 &
0x3f) = 0x20 = 32.
- qcom,hsdisc-trim-value: sets "PORT_TUNE2", lower 2 bits. Driver
programs PORT_TUNE2 to 0x29 by default and (0x29 & 0x3) = 1.

There's several cases of json-schema 'additionalProperties' at the wrong
indentation level which has the effect of making them DT properties. This
is harmless, but let's fix them so a meta-schema check for this can be
added.
In all the cases, either the 'additionalProperties' was extra or doesn't
work because there's a $ref to more properties. In the latter case, we
can use 'unevaluatedProperties' instead.

IORING_OP_MADVISE can end up basically doing mprotect() on the VM of
another process, which means that it can race with our crazy core dump
handling which accesses the VM state without holding the mmap_sem
(because it incorrectly thinks that it is the final user).
This is clearly a core dumping problem, but we've never fixed it the
right way, and instead have the notion of "check that the mm is still
ok" using mmget_still_valid() after getting the mmap_sem for writing in
any situation where we're not the original VM thread.
See commit 04f5866e41 ("coredump: fix race condition between
mmget_not_zero()/get_task_mm() and core dumping") for more background on
this whole mmget_still_valid() thing. You might want to have a barf bag
handy when you do.
We're discussing just fixing this properly in the only remaining core
dumping routines. But even if we do that, let's make do_madvise() do
the right thing, and then when we fix core dumping, we can remove all
these mmget_still_valid() checks.

The checks of the plugin buffer overflow in the previous fix by commit
f2ecf903ef ("ALSA: pcm: oss: Avoid plugin buffer overflow")
are put in the wrong places mistakenly, which leads to the expected
(repeated) sound when the rate plugin is involved. Fix in the right
places.
Also, at those right places, the zero check is needed for the
termination node, so added there as well, and let's get it done,
finally.

The call to ->lookup_put() was too early and it caused an unlock of the
read/write protection of the uobject after the FD was put. This allows a
race:
CPU1 CPU2
rdma_lookup_put_uobject()
lookup_put_fd_uobject()
fput()
fput()
uverbs_uobject_fd_release()
WARN_ON(uverbs_try_lock_object(uobj,

Fix the code by changing the order, first unlock and call to
->lookup_put() after that.

We don't care which process calls do_fork so just check the first record to
fix the issue.

When an operation is meant to be done uninterruptibly (such as
FS.StoreData), we should not be allowing volume and server record checking
to be interrupted.

AFS keeps track of the epoch value from the rxrpc protocol to note (a) when
a fileserver appears to have restarted and (b) when different endpoints of
a fileserver do not appear to be associated with the same fileserver
(ie. all probes back from a fileserver from all of its interfaces should
carry the same epoch).
However, the AFS_SERVER_FL_HAVE_EPOCH flag that indicates that we've
received the server's epoch is never set, though it is used.
Fix this to set the flag when we first receive an epoch value from a probe
sent to the filesystem client from the fileserver.

Remove three bits:
(1) afs_server::no_epoch is neither set nor used.
(2) afs_server::have_result is set and a wakeup is applied to it, but
nothing looks at it or waits on it.
(3) afs_vl_dump_edestaddrreq() prints afs_addr_list::probed, but nothing
sets it for VL servers.

As the number of schemas has increased, we're starting to hit the error
"execvp: /bin/sh: Argument list too long". This is due to passing all the
schema files on the command line to dt-mk-schema. It currently is only
with out of tree builds and is intermittent depending on the file path
lengths.
Commit 2ba06cd856 ("kbuild: Always validate DT binding examples") made
hitting this proplem more likely since the example validation now always
gets the full list of schemas.
Fix this by passing the schema file list in a pipe and using xargs. We end
up doing the find twice, but the time is insignificant compared to the
dt-mk-schema time.

[why]
We have seen a green screen after resume from suspend in a Raven system
connected with two displays (HDMI and DP) on X based system. We noticed
that this issue is related to bad DCC metadata from user space which may
generate hangs and consequently an underflow on HUBP. After taking a
deep look at the code path we realized that after resume we try to
restore the commit with the DCC enabled framebuffer but the framebuffer
is no longer valid.
[how]
This problem was only reported on Raven based system and after suspend,
for this reason, this commit adds a new parameter on
fill_plane_dcc_attributes() to give the option of disabling DCC
programmatically. In summary, for disabling DCC we first verify if is a
Raven system and if it is in suspend; if both conditions are true we
disable DCC temporarily, otherwise, it is enabled.
