This is the cleanup of the latest series of prandom_u32

The changes to the files were kept minimal, and the controversial
commit that used to take noise from the fast_pool (

reverted. Instead, a dedicated "net_rand_noise" per_cpu variable is
fed from various sources of activities (networking, scheduling) to
perturb the SipHash state using fast, non-trivially predictable data,
instead of keeping it fully deterministic. The goal is essentially to
make any occasional memory leakage or brute-force attempt useless.
The resulting code was verified to be very slightly faster on x86_64
than what is was with the controversial commit above, though this
remains barely above measurement noise. It was also tested on i386 and

i2c: core: Restore acpi_walk_dep_device_list() getting called after registering the ACPI i2c devs
Commit
21653a4181ff ("i2c: core: Call i2c_acpi_install_space_handler()
before i2c_acpi_register_devices()")'s intention was to only move the
acpi_install_address_space_handler() call to the point before where
the ACPI declared i2c-children of the adapter where instantiated by
i2c_acpi_register_devices().
But i2c_acpi_install_space_handler() had a call to
acpi_walk_dep_device_list() hidden (that is I missed it) at the end
of it, so as an unwanted side-effect now acpi_walk_dep_device_list()
was also being called before i2c_acpi_register_devices().
Move the acpi_walk_dep_device_list() call to the end of
i2c_acpi_register_devices(), so that it is once again called *after*
the i2c_client-s hanging of the adapter have been created.
This fixes the Microsoft Surface Go 2 hanging at boot.

random32: add noise from network and scheduling activity
With the removal of the interrupt perturbations in previous random32
change (random32: make prandom_u32() output unpredictable), the PRNG
has become 100% deterministic again. While SipHash is expected to be
way more robust against brute force than the previous Tausworthe LFSR,
there's still the risk that whoever has even one temporary access to
the PRNG's internal state is able to predict all subsequent draws till
the next reseed (roughly every minute). This may happen through a side
channel attack or any data leak.
This patch restores the spirit of commit
f227e3ec3b5c ("random32: update
the net random state on interrupt and activity") in that it will perturb
the internal PRNG's statee using externally collected noise, except that
it will not pick that noise from the random pool's bits nor upon
interrupt, but will rather combine a few elements along the Tx path
that are collectively hard to predict, such as dev, skb and txq
pointers, packet length and jiffies values. These ones are combined
using a single round of SipHash into a single long variable that is
mixed with the net_rand_state upon each invocation.
The operation was inlined because it produces very small and efficient
code, typically 3 xor, 2 add and 2 rol. The performance was measured
to be the same (even very slightly better) than before the switch to
SipHash; on a 6-core 12-thread Core i7-8700k equipped with a 40G NIC
(i40e), the connection rate dropped from 556k/s to 555k/s while the
SYN cookie rate grew from 5.38 Mpps to 5.45 Mpps.

random32: make prandom_u32() output unpredictable
Non-cryptographic PRNGs may have great statistical properties, but
are usually trivially predictable to someone who knows the algorithm,
given a small sample of their output. An LFSR like prandom_u32() is
particularly simple, even if the sample is widely scattered bits.
It turns out the network stack uses prandom_u32() for some things like
random port numbers which it would prefer are *not* trivially predictable.
Predictability led to a practical DNS spoofing attack. Oops.
This patch replaces the LFSR with a homebrew cryptographic PRNG based
on the SipHash round function, which is in turn seeded with 128 bits
of strong random key. (The authors of SipHash have *not* been consulted
about this abuse of their algorithm.) Speed is prioritized over security;
attacks are rare, while performance is always wanted.
Replacing all callers of prandom_u32() is the quick fix.
Whether to reinstate a weaker PRNG for uses which can tolerate it
is an open question.
Commit
f227e3ec3b5c ("random32: update the net random state on interrupt

KVM: ioapic: break infinite recursion on lazy EOI
During shutdown the IOAPIC trigger mode is reset to edge triggered
while the vfio-pci INTx is still registered with a resampler.
This allows us to get into an infinite loop:
ioapic_set_irq
-> ioapic_lazy_update_eoi
-> kvm_ioapic_update_eoi_one
-> kvm_notify_acked_irq
-> kvm_notify_acked_gsi
-> (via irq_acked fn ptr) irqfd_resampler_ack
-> kvm_set_irq
-> (via set fn ptr) kvm_set_ioapic_irq
-> kvm_ioapic_set_irq
-> ioapic_set_irq
Commit
8be8f932e3db ("kvm: ioapic: Restrict lazy EOI update to
edge-triggered interrupts", 2020-05-04) acknowledges that this recursion
loop exists and tries to avoid it at the call to ioapic_lazy_update_eoi,
but at this point the scenario is already set, we have an edge interrupt
with resampler on the same gsi.
Fortunately, the only user of irq ack notifiers (in addition to resamplefd)
is i8254 timer interrupt reinjection. These are edge-triggered, so in
principle they would need the call to kvm_ioapic_update_eoi_one from
ioapic_lazy_update_eoi, but they already disable AVIC(*), so they don't
need the lazy EOI behavior. Therefore, remove the call to
kvm_ioapic_update_eoi_one from ioapic_lazy_update_eoi.
This fixes CVE-2020-27152. Note that this issue cannot happen with
SR-IOV assigned devices because virtual functions do not have INTx,
only MSI.

x86/uaccess: fix code generation in put_user()
Quoting https://gcc.gnu.org/onlinedocs/gcc/Local-Register-Variables.html:
You can define a local register variable and associate it with a
specified register...
The only supported use for this feature is to specify registers for
input and output operands when calling Extended asm (see Extended
Asm). This may be necessary if the constraints for a particular
machine don't provide sufficient control to select the desired
register.
On 32-bit x86, this is used to ensure that gcc will put an 8-byte value
into the %edx:%eax pair, while all other cases will just use the single
register %eax (%rax on x86-64). While the _ASM_AX actually just expands
to "%eax", note this comment next to get_user() which does something
very similar:
* The use of _ASM_DX as the register specifier is a bit of a
* simplification, as gcc only cares about it as the starting point
* and not size: for a 64-bit value it will use %ecx:%edx on 32 bits
* (%ecx being the next register in gcc's x86 register sequence), and
* %rdx on 64 bits.
However, getting this to work requires that there is no code between the
assignment to the local register variable and its use as an input to the
asm() which can possibly clobber any of the registers involved -
including evaluation of the expressions making up other inputs.
In the current code, the ptr expression used directly as an input may
cause such code to be emitted. For example, Sean Christopherson
observed that with KASAN enabled and ptr being current->set_child_tid
(from chedule_tail()), the load of current->set_child_tid causes a call
to __asan_load8() to be emitted immediately prior to the __put_user_4
call, and Naresh Kamboju reports that various mmstress tests fail on
KASAN-enabled builds.
It's also possible to synthesize a broken case without KASAN if one uses
"foo()" as the ptr argument, with foo being some "extern u64 __user
*foo(void);" (though I don't know if that appears in real code).
Fix it by making sure ptr gets evaluated before the assignment to
__val_pu, and add a comment that __val_pu must be the last thing
computed before the asm() is entered.

parisc: Add wrapper syscalls to fix O_NONBLOCK flag usage
The commit
75ae04206a4d ("parisc: Define O_NONBLOCK to become
000200000") changed the O_NONBLOCK constant to have only one bit set
(like all other architectures). This change broke some existing
userspace code (e.g. udevadm, systemd-udevd, elogind) which called
specific syscalls which do strict value checking on their flag
parameter.
This patch adds wrapper functions for the relevant syscalls. The
wrappers masks out any old invalid O_NONBLOCK flags, reports in the
syslog if the old O_NONBLOCK value was used and then calls the target
syscall with the new O_NONBLOCK value.

ASoC: cs42l51: manage mclk shutdown delay
A delay must be introduced before the shutdown down of the mclk,
as stated in CS42L51 datasheet. Otherwise the codec may
produce some noise after the end of DAPM power down sequence.
The delay between DAC and CLOCK_SUPPLY widgets is too short.
Add a delay in mclk shutdown request to manage the shutdown delay
explicitly. From experiments, at least 10ms delay is necessary.
Set delay to 20ms as recommended in Documentation/timers/timers-howto.rst
when using msleep().

ASoC: qcom: sdm845: set driver name correctly
With the current state of code, we would endup with something like
below in /proc/asound/cards for 2 machines based on this driver.
Machine 1:
0 [DB845c ]: DB845c - DB845c
DB845c
Machine 2:
0 [LenovoYOGAC6301]: Lenovo-YOGA-C63 - Lenovo-YOGA-C630-13Q50
LENOVO-81JL-LenovoYOGAC630_13Q50-LNVNB161216
This is not very UCM friendly both w.r.t to common up configs and
card identification, and UCM2 became totally not usefull with just
one ucm sdm845.conf for two machines which have different setups
w.r.t HDMI and other dais.
Reasons for such thing is partly because Qualcomm machine drivers never
cared to set driver_name.
This patch sets up driver name for the this driver to sort out the
UCM integration issues!
after this patch contents of /proc/asound/cards:
Machine 1:
0 [DB845c ]: sdm845 - DB845c
DB845c
Machine 2:
0 [LenovoYOGAC6301]: sdm845 - Lenovo-YOGA-C630-13Q50
LENOVO-81JL-LenovoYOGAC630_13Q50-LNVNB161216
with this its possible to align with what UCM2 expects and we can have
sdm845/DB845.conf
sdm845/LENOVO-81JL-LenovoYOGAC630_13Q50-LNVNB161216.conf
... for board variants. This should scale much better!

gfs2: Recover statfs info in journal head
Apply the outstanding statfs changes in the journal head to the
master statfs file. Zero out the local statfs file for good measure.
Previously, statfs updates would be read in from the local statfs inode and
synced to the master statfs inode during recovery.
We now use the statfs updates in the journal head to update the master statfs
inode instead of reading in from the local statfs inode. To preserve backward
compatibility with kernels that can't do this, we still need to keep the
local statfs inode up to date by writing changes to it. At some point in the
future, we can do away with the local statfs inodes altogether and keep the
statfs changes solely in the journal.
