pull-request: bpf 2020-03-27

The following pull-request contains BPF updates for your *net* tree.

We've added 3 non-merge commits during the last 4 day(s) which contain
a total of 4 files changed, 25 insertions(+), 20 deletions(-).

The main changes are:

1) Explicitly memset the bpf_attr structure on bpf() syscall to avoid
   having to rely on compiler to do so. Issues have been noticed on
   some compilers with padding and other oddities where the request was
   then unexpectedly rejected, from Greg Kroah-Hartman.

On Android/x86 the module loading infrastructure can't deal with
softdeps. Therefore the check for presence of the Realtek PHY driver
module fails. mdiobus_register() will try to load the PHY driver
module, therefore move the check to after this call and explicitly
check that a dedicated PHY driver is bound to the PHY device.

Pull ARM DT and driver fixes from Arnd Bergmann:
 "For the devicetree files, there are a total of 20 patches, almost
  entirely for 32-bit machines:

   - The Allwinner/sun9i r40 SoC dtsi file contains a number of issues,
     both for correctness and for style that are addressed in separate
     patches. This causes most of the changed lines of the DT updates
     this time.

   - More Allwinner updates fixing the identification of the security
     system on sun8i/A33, a recent regression of the A83t ethernet, and
     a few board specific issues on the TBS-A711 macine.

   - Several bug fixes for OMAP dts files, most notably fixing the
     timings for the NAND flash on the Nokia N900 that regressed a while
     ago after the move to configuring them from DT. Some other OMAPs
     now set the correct dma limits on the L3 bus, and a regression fix
     addresses lost Ethernet on dm814x

   - One incorrect setting in the newly added Raspberry Pi Zero W that
     may cause issues with the SD card controller.

   - A missing property on the bcm2835 firmware node caused incorrect
     DMA settings.

   - An old bug on the oxnas platform causing spurious interrupts is
     finally addressed.

   - A regression on the Exynos Midas board broke the OLED panel power
     supply.

   - The i.MX6 phycore SoM specified the wrong voltage for the SoC, this
     is now set to the values from the datasheet.

   - Some 64-bit machines use a deprecated string to identify the PSCI
     firmware.

  There are also several small code fixes addressing mostly serious
  issues:

   - Fix the sunxi rsb bus access to no longer return incorrect data
     when mixing 8 and 16 bit I/O.

   - Fix a suspend/resume regression on the OMAP2+ lcdc from a missing
     quirk in the ti-sysc driver

   - Fix a NULL pointer access from a race in the fsl dpio driver

   - Fix a v5.5 regression in the exynos-chipid driver that caused an
     invalid error code probing the device on non-exynos platforms

This is because both dtc-lexer as well as dtc-parser define the same
global symbol yyloc. Before with -fcommon those were merged into one
defintion. The proper solution would be to to mark this as "extern",
however that leads to:

This patch reverts 58292104 ("net: ks8851-ml: Fix 16-bit IO operation")
and edacb098 ("net: ks8851-ml: Fix 16-bit data access"), because it
turns out these were only necessary due to buggy hardware. This patch adds
a check for such a buggy hardware to prevent any such mistakes again.

While working further on the KS8851 driver, it came to light that the
KS8851-16MLL is capable of switching bus endianness by a hardware strap,
EESK pin. If this strap is incorrect, the IO accesses require such endian
swapping as is being reverted by this patch. Such swapping also impacts
the performance significantly.

Hence, in addition to removing it, detect that the hardware is broken,
report to user, and fail to bind with such hardware.

When it's probing all of a fileserver's interfaces to find which one is
best to use, afs_do_probe_fileserver() takes a lock on the server record
and notes the pointer to the address list.

It doesn't, however, pin the address list, so as soon as it drops the
lock, there's nothing to stop the address list from being freed under
us.

Fix this by taking a ref on the address list inside the locked section
and dropping it at the end of the function.

this will lead to wrong decisions (rate control etc.) being made
about the frame; fix this.

If a station is still marked as authorized, mark it as no longer
so before removing its keys. This allows frames transmitted to it
to be rejected, providing additional protection against leaking
plain text data during the disconnection flow.

mac80211 used to check port authorization in the Data frame enqueue case
when going through start_xmit(). However, that authorization status may
change while the frame is waiting in a queue. Add a similar check in the
dequeue case to avoid sending previously accepted frames after
authorization change. This provides additional protection against
potential leaking of frames after a station has been disconnected and
the keys for it are being removed.

When cfg80211_update_assoc_bss_entry() is called, there is a
verification that the BSS channel actually changed. As some APs use
CSA also for bandwidth changes, this would result with a kernel
warning.

Fix this by removing the WARN_ON().

If we know that we have an encrypted link (based on having had
a key configured for TX in the past) then drop all data frames
in the key selection handler if there's no key anymore.

This fixes an issue with mac80211 internal TXQs - there we can
buffer frames for an encrypted link, but then if the key is no
longer there when they're dequeued, the frames are sent without
encryption. This happens if a station is disconnected while the
frames are still on the TXQ.

Detecting that a link should be encrypted based on a first key
having been configured for TX is fine as there are no use cases
for a connection going from with encryption to no encryption.
With extended key IDs, however, there is a case of having a key
configured for only decryption, so we can't just trigger this
behaviour on a key being configured.

There is one one corner case at dma_fence_signal_locked
which will raise the NULL pointer problem just like below.
->dma_fence_signal
    ->dma_fence_signal_locked
	->test_and_set_bit
here trigger dma_fence_release happen due to the zero of fence refcount.

->dma_fence_put
    ->dma_fence_release
	->drm_sched_fence_release_scheduled
	    ->call_rcu
here make the union fled “cb_list” at finished fence
to NULL because struct rcu_head contains two pointer
which is same as struct list_head cb_list

Therefore, to hold the reference of finished fence at drm_sched_process_job
to prevent the null pointer during finished fence dma_fence_signal
