Vignesh Raghavendra [Mon, 22 Apr 2019 16:13:32 +0000 (21:43 +0530)]
arch: armv8: Provide a way to disable cache maintenance ops

On AM654 SoC(arm64) which is IO coherent and has L3 Cache, cache
maintenance operations being done to support non-coherent platforms
causes issues.

For example, here is how U-Boot prepares/handles a buffer to receive
data from a device (DMA Write). This may vary slightly depending on the
driver framework:

Start DMA to write to destination buffer
Wait for DMA to be done (dma_receive()/dma_memcpy())
Invalidate destination buffer (invalidate_dcache_range())
Read from destination buffer

The invalidate after the DMA is needed in order to read latest data from
memory that’s updated by DMA write. Also, in case random prefetch has
pulled in buffer data during the “wait for DMA” before the DMA has
written to it. This works well for non-coherent architectures.

In case of coherent architecture with L3 cache, DMA write would directly
update L3 cache contents (assuming cacheline is present in L3) without
updating the DDR memory. So invalidate after “wait for DMA” in above
sequence would discard latest data and read will cause stale data to be
fetched from DDR. Therefore invalidate after “wait for DMA” is not
always correct on coherent architecture.

Therefore, provide a Kconfig option to disable cache maintenance ops on
coherent architectures. This has added benefit of improving the
performance of DMA transfers as we no longer need to invalidate/flush
individual cache lines(especially for buffer thats several KBs in size).

In order to facilitate use of same Kconfig across different
architecture, I have added the symbol to top level arch/Kconfig file.
Patch currently disables cache maintenance ops for arm64 only.
flush_dcache_all() and invalidate_dcache_all() are exclusively used
during enabling/disabling dcache and hence are not disabled.

i2c: mvtwsi: fix reading status register after interrupt

The twsi_wait function reads the control register for interrupt flag,
and if interrupt flag is present, it immediately reads status register.

On our device this sometimes causes bad value being read from status
register, as if the value was not yet updated.

My theory is that the controller does approximately this:
  1. sets interrupt flag in control register,
  2. sets the value of status register,
  3. causes an interrupt

In U-Boot we do not use interrupts, so I think that it is possible that
sometimes the status register in the twsi_wait function is read between
points 1 and 2.

The bug does not appear if I add a small delay before reading status
register.

Wait 100ns (which in U-Boot currently means 1 us, because ndelay(i)
function calls udelay(DIV_ROUND_UP(i, 1000))) before reading the status
register.

arm: mvebu: turris_omnia: add RESET button handling

There is a Factory RESET button on the back side of the Turris Omnia
router. When user presses this button before powering the device up and
keeps it pressed, the microcontroller prevents the main CPU from booting
and counts how long the RESET button is being pressed (and indicates
this by lighting up front LEDs).

The idea behind this is that the user can boot the device into several
Factory RESET modes.

This patch adds support for U-Boot to read into which Factory RESET mode
the user booted the device. The value is an integer stored into the
omnia_reset environment variable. It is 0 if the button was not pressed
at all during power up, otherwise it is the number identifying the
Factory RESET mode.

This patch also changes bootcmd to a special hardcoded value if Factory
RESET button was pressed during device powerup. This special bootcmd
value sets the colors of all the LEDs on the front panel to green and
then tries to load the rescue image from the SPI flash memory and boot
it.

lib: uuid: Fix unseeded PRNG on RANDOM_UUID=y

The random uuid values (enabled via CONFIG_RANDOM_UUID=y) on our
platform are always the same. Below is consistent on each cold boot:

 => ### interrupt autoboot
 => env default -a; gpt write mmc 1 $partitions; print uuid_gpt_misc
 ...
 uuid_gpt_misc=d117f98e-6f2c-d04b-a5b2-331a19f91cb2
 => env default -a; gpt write mmc 1 $partitions; print uuid_gpt_misc
 ...
 uuid_gpt_misc=ad5ec4b6-2d9f-8544-9417-fe3bd1c9b1b3
 => env default -a; gpt write mmc 1 $partitions; print uuid_gpt_misc
 ...
 uuid_gpt_misc=cceb0b18-39cb-d547-9db7-03b405fa77d4
 => env default -a; gpt write mmc 1 $partitions; print uuid_gpt_misc
 ...
 uuid_gpt_misc=d4981a2b-0478-544e-9607-7fd3c651068d
 => env default -a; gpt write mmc 1 $partitions; print uuid_gpt_misc
 ...
 uuid_gpt_misc=6d6c9a36-e919-264d-a9ee-bd00379686c7

While the uuids do change on every 'gpt write' command, the values
appear to be taken from the same pool, in the same order.

Assuming U-Boot with RANDOM_UUID=y is deployed on a large number of
devices, all those devices would essentially expose the same UUID,
breaking the assumption of system/RFS/application designers who rely
on UUID as being globally unique (e.g. a database using UUID as key
would alias/mix up entries/records due to duplicated UUID).

The root cause seems to be simply _not_ seeding PRNG before generating
a random value. It turns out this belongs to an established class of
PRNG-specific problems, commonly known as "unseeded randomness", for
which I am able to find below bugs/CVE/CWE:
 - https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2015-0285
   ("CVE-2015-0285 openssl: handshake with unseeded PRNG")
 - https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2015-9019
   ("CVE-2015-9019 libxslt: math.random() in xslt uses unseeded
   randomness")
 - https://cwe.mitre.org/data/definitions/336.html
   ("CWE-336: Same Seed in Pseudo-Random Number Generator (PRNG)")

The first revision [1] of this patch updated the seed based on the
output of get_timer(), similar to [4].

There are two problems with this approach:
 - get_timer() has a poor _ms_ resolution
 - when gen_rand_uuid() is called in a loop, get_timer() returns the
   same result, leading to the same seed being passed to srand(),
   leading to the same uuid being generated for several partitions
   with different names

The above drawbacks have been addressed in the second version [2].
In its third revision (current), the patch reworded the description
and summary line to emphasize it is a *fix* rather than an improvement.

Testing [3] consisted of running 'gpt write mmc 1 $partitions' in a
loop on R-Car3 for several minutes, collecting 8844 randomly generated
UUIDS. Two consecutive cold boots are concatenated in the log.
As a result, all uuid values are unique (scripted check).

Thanks to Roman, who reported the issue and provided support in fixing.
