arm64: dts: qcom: sc7180: Assign numbers to eMMC and SD
After many years of struggle, commit
fa2d0aa96941 ("mmc: core: Allow
setting slot index via device tree alias") finally allows the use of
aliases to number SD/MMC slots. Let's do that for sc7180 SoCs so that
if eMMC and SD are both used they have consistent numbers across boots
and kernel changes.
Picking numbers can be tricky. Do we call these "1" and "2" to match
the name in documentation or "0" and "1" with the assertion that we
should always start at 0 and count up?
While the "start counting at 0" makes sense if there are not already
well-defined numbers for all sd/mmc controllers, in the case of sc7180
there _are_ well defined numbers. IMO it is less confusing to use
those and match the docs.

arm64: dts: qcom: Switch sc7180-trogdor to control SPI CS via GPIO
As talked about in the patch ("arm64: dts: qcom: sc7180: Provide
pinconf for SPI to use GPIO for CS"), on some boards it makes much
more sense (and is much more efficient) to think of the SPI Chip
Select as a GPIO. Trogdor is one such board where the SPI parts don't
run in GSI mode and we do a lot of SPI traffic.

arm64: dts: qcom: sc7180: Provide pinconf for SPI to use GPIO for CS
When the chip select line is controlled by the QUP, changing CS is a
time consuming operation. We have to send a command over to the geni
and wait for it to Ack us every time we want to change (both making it
high and low). To send this command we have to make a choice in
software when we want to control the chip select, we have to either:
A) Wait for the Ack via interrupt which slows down all SPI transfers
(and incurrs extra processing associated with interrupts).
B) Sit in a loop and poll, waiting for the Ack.
Neither A) nor B) is a great option.
We can avoid all of this by realizing that, at least on some boards,
there is no advantage of considering this line to be a geni line.
While it's true that geni _can_ control the line, it's also true that
the line can be a GPIO and there is no downside of viewing it that
way. Setting a GPIO is a simple MMIO operation.
This patch provides definitions so a board can easily select the GPIO
mode.
NOTE: apparently, it's possible to run the geni in "GSI" mode. In GSI
the SPI port is allowed to be controlled by more than one user (like
firmware and Linux) and also the port can operate sequences of
operations in one go. In GSI mode it _would_ be invalid to look at
the chip select as a GPIO because that would prevent other users from
using it. In theory GSI mode would also avoid some overhead by
allowing us to sequence the chip select better. However, I'll argue
GSI is not relevant for all boards (and certainly not any boards
supported by mainline today). Why?
- Apparently to run a SPI chip in GSI mode you need to initialize it
(in the bootloader) with a different firmware and then it will
always run in GSI mode. Since there is no support for GSI mode in
the current Linux driver, it must be that existing boards don't have
firmware that's doing that. Note that the kernel device tree
describes hardware but also firmware, so it is legitimate to make
the assumption that we don't have GSI firmware in a given dts file.
- Some boards with sc7180 have SPI connected to the Chrome OS EC or
security chip (Cr50). The protocols for talking to cros_ec and cr50
are extremely complex. Both drivers in Linux fully lock the bus
across several distinct SPI transfers. While I am not an expert on
GSI mode it feels highly unlikely to me that we'd ever be able to
enable GSI mode for these devices.
From a testing perspective, running "flashrom -p ec -r /tmp/foo.bin"
in a loop after this patch shows almost no reduction in time, but the
number of interrupts per command goes from 32357 down to 30611 (about
a 5% reduction).

Move the acpi_walk_dep_device_list() call to the end of

the i2c_client-s hanging of the adapter have been created.

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

it.

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.

Merge tag 'gfs2-for-5.10' of git://git./linux/kernel/git/gfs2/linux-gfs2
Pull gfs2 updates from Andreas Gruenbacher:
- Use iomap for non-journaled buffered I/O. This largely eliminates
buffer heads on filesystems where the block size matches the page
size. Many thanks to Christoph Hellwig for this patch!
- Fixes for some more journaled data filesystem bugs, found by running
xfstests with data journaling on for all files (chattr +j $MNT) (Bob
Peterson)
- gfs2_evict_inode refactoring (Bob Peterson)
- Use the statfs data in the journal during recovery instead of reading
it in from the local statfs inodes (Abhi Das)
- Several other minor fixes by various people
