Now the debugfs files dais/platforms/codecs have a size limit PAGE_SIZE and
the user can not see the whole contents of dai_list/platform_list/codec_list
when they are larger than this limit.
This patch uses seq_file instead to make sure dais/platforms/codecs show the
full contents of dai_list/platform_list/codec_list.

If bcm2835 is configured as bitclock master calling hw_params()
after prepare() fails with EBUSY. This also makes it impossible to
use bcm2835 in full duplex mode.
The error is caused by the split clock setup: clk_set_rate
is called in hw_params, clk_prepare_enable in prepare. As hw_params
doesn't check if the clock was already enabled clk_set_rate
fails with EBUSY.
Fix this by moving clock startup from prepare to hw_params and
let hw_params properly deal with an already set up or enabled
clock.

Some issues have been reported with the for loop in stop_this_cpu() that
issues the 'wbinvd; hlt' sequence. Reverting this sequence to halt()
has been shown to resolve the issue.
However, the wbinvd is needed when running with SME. The reason for the
wbinvd is to prevent cache flush races between encrypted and non-encrypted
entries that have the same physical address. This can occur when
kexec'ing from memory encryption active to inactive or vice-versa. The
important thing is to not have outside of kernel text memory references
(such as stack usage), so the usage of the native_*() functions is needed
since these expand as inline asm sequences. So instead of reverting the
change, rework the sequence.
Move the wbinvd instruction outside of the for loop as native_wbinvd()
and make its execution conditional on X86_FEATURE_SME. In the for loop,
change the asm 'wbinvd; hlt' sequence back to a halt sequence but use
the native_halt() call.

Keith reported an issue with vector space exhaustion on a server machine
which is caused by the i40e driver allocating 168 MSI interrupts when the
driver is initialized, even when most of these interrupts are not used at
all.
The x86 vector allocation code tries to avoid the immediate allocation with
the reservation mode, but the card uses MSI and does not support MSI entry
masking, which prevents reservation mode and requires immediate vector
allocation.
The matrix allocator is a bit naive and prefers the first CPU in the
cpumask which describes the possible target CPUs for an allocation. That
results in allocating all 168 vectors on CPU0 which later causes vector
space exhaustion when the NVMe driver tries to allocate managed interrupts
on each CPU for the per CPU queues.
Avoid this by finding the CPU which has the lowest vector allocation count
to spread out the non managed interrupt accross the possible target CPUs.

Current code configures the hardware with a new SA before the state has been
fully initialized. During this time interval, an incoming ESP packet can cause
a crash due to a NULL dereference. More specifically, xfrm_input() considers
the packet as valid, and yet, anti-replay mechanism is not initialized.
Move hardware configuration to the end of xfrm_state_construct(), and mark
the state as valid once the SA is fully initialized.

If an invalid CANFD frame is received, from a driver or from a tun
interface, a Kernel warning is generated.
This patch replaces the WARN_ONCE by a simple pr_warn_once, so that a
kernel, bootet with panic_on_warn, does not panic. A printk seems to be
more appropriate here.

syzkaller generated a BPF proglet and triggered a warning with
the following:
0: (b7) r0 = 0
1: (d5) if r0 s<= 0x0 goto pc+0
R0=inv0 R1=ctx(id=0,off=0,imm=0) R10=fp0
2: (1f) r0 -= r1
R0=inv0 R1=ctx(id=0,off=0,imm=0) R10=fp0
verifier internal error: known but bad sbounds
What happens is that in the first insn, r0's min/max value
are both 0 due to the immediate assignment, later in the jsle
test the bounds are updated for the min value in the false
path, meaning, they yield smin_val = 1, smax_val = 0, and when
ctx pointer is subtracted from r0, verifier bails out with the
internal error and throwing a WARN since smin_val != smax_val
for the known constant.
For min_val > max_val scenario it means that reg_set_min_max()
and reg_set_min_max_inv() (which both refine existing bounds)
demonstrated that such branch cannot be taken at runtime.
In above scenario for the case where it will be taken, the
existing [0, 0] bounds are kept intact. Meaning, the rejection
is not due to a verifier internal error, and therefore the
WARN() is not necessary either.
We could just reject such cases in adjust_{ptr,scalar}_min_max_vals()
when either known scalars have smin_val != smax_val or
umin_val != umax_val or any scalar reg with bounds
smin_val > smax_val or umin_val > umax_val. However, there
may be a small risk of breakage of buggy programs, so handle
this more gracefully and in adjust_{ptr,scalar}_min_max_vals()
just taint the dst reg as unknown scalar when we see ops with
such kind of src reg.

Running the following sequence is currently broken:
# tc qdisc add dev foo clsact
# tc filter replace dev foo ingress prio 1 handle 1 bpf da obj bar.o
# tc filter replace dev foo ingress prio 1 handle 1 bpf da obj bar.o
RTNETLINK answers: Invalid argument
The normal expectation on kernel side is that the second command
succeeds replacing the existing program. However, what happens is
in cls_bpf_change(), we bail out with err in the second run in
cls_bpf_offload(). The EINVAL comes directly in cls_bpf_offload()
when comparing prog vs oldprog's gen_flags. In case of above
replace the new prog's gen_flags are 0, but the old ones are 8,
which means TCA_CLS_FLAGS_NOT_IN_HW is set (e.g. drivers not having
cls_bpf offload).
Fix 102740bd9436 ("cls_bpf: fix offload assumptions after callback
conversion") in the following way: gen_flags from user space passed
down via netlink cannot include status flags like TCA_CLS_FLAGS_IN_HW
or TCA_CLS_FLAGS_NOT_IN_HW as opposed to oldprog that we previously
loaded. Therefore, it doesn't make any sense to include them in the
gen_flags comparison with the new prog before we even attempt to
offload. Thus, lets fix this before 4.15 goes out.

In the receive queue for 4096 bytes fragments, the page address
set in the SW data0 field of the descriptor is not the one we got
when doing the reassembly in receive. The page structure was retrieved

The current code copies directly from userspace to ctx->crypto_send, but
doesn't always reinitialize it to 0 on failure. This causes any
subsequent attempt to use this setsockopt to fail because of the
TLS_CRYPTO_INFO_READY check, eventhough crypto_info is not actually
ready.
This should result in a correctly set up socket after the 3rd call, but
currently it does not:
size_t s = sizeof(struct tls12_crypto_info_aes_gcm_128);
struct tls12_crypto_info_aes_gcm_128 crypto_good = {
.info.version = TLS_1_2_VERSION,
.info.cipher_type = TLS_CIPHER_AES_GCM_128,
};
struct tls12_crypto_info_aes_gcm_128 crypto_bad_type = crypto_good;
crypto_bad_type.info.cipher_type = 42;

Calling accept on a TCP socket with a TLS ulp attached results
in two sockets that share the same ulp context.
The ulp context is freed while a socket is destroyed, so
after one of the sockets is released, the second second will
trigger a use after free when it tries to access the ulp context
attached to it.
We restrict the TLS ulp to sockets in ESTABLISHED state
to prevent the scenario above.

r8153 on Dell TB15/16 dock corrupts rx packets.
This change is suggested by Realtek. They guess that the XHCI controller
doesn't have enough buffer, and their guesswork is correct, once the RX
aggregation gets disabled, the issue is gone.
ASMedia is currently working on a real sulotion for this issue.
Dell and ODM confirm the bcdDevice and iSerialNumber is unique for TB16.
Note that TB15 has different bcdDevice and iSerialNumber, which are not
unique values. If you still have TB15, please contact Dell to replace it
with TB16.

Pull x86 fixes from Ingo Molnar:
"Misc fixes:
- A rather involved set of memory hardware encryption fixes to
support the early loading of microcode files via the initrd. These
are larger than what we normally take at such a late -rc stage, but
there are two mitigating factors: 1) much of the changes are
limited to the SME code itself 2) being able to early load
microcode has increased importance in the post-Meltdown/Spectre
era.
- An IRQ vector allocator fix
- An Intel RDT driver use-after-free fix
- An APIC driver bug fix/revert to make certain older systems boot
again
- A pkeys ABI fix
- TSC calibration fixes
- A kdump fix"

tfile->tun could be detached before we close the tun fd,
via tun_detach_all(), so it should not be used to check for
tfile->tx_array.
As Jason suggested, we probably have to clean it up
unconditionally both in __tun_deatch() and tun_detach_all(),
but this requires to check if it is initialized or not.
Currently skb_array_cleanup() doesn't have such a check,
so I check it in the caller and introduce a helper function,
it is a bit ugly but we can always improve it in net-next.

Pull x86 pti bits and fixes from Thomas Gleixner:
"This last update contains:
- An objtool fix to prevent a segfault with the gold linker by
changing the invocation order. That's not just for gold, it's a
general robustness improvement.
- An improved error message for objtool which spares tearing hairs.
- Make KASAN fail loudly if there is not enough memory instead of
oopsing at some random place later
- RSB fill on context switch to prevent RSB underflow and speculation
through other units.
- Make the retpoline/RSB functionality work reliably for both Intel
and AMD
- Add retpoline to the module version magic so mismatch can be
detected
- A small (non-fix) update for cpufeatures which prevents cpu feature
clashing for the upcoming extra mitigation bits to ease
backporting"
