      usb: xhci: dbc: Fix lockdep warning · a098dc8b
      Lu Baolu authored 
      The xHCI DbC implementation might enter a deadlock situation because
there is no sufficient protection against the shared data between
process and softirq contexts. This can lead to the following lockdep
warnings. This patch changes to use spin_{,un}lock_irq{save,restore}
to avoid potential deadlock.

usb: fixes for v4.16-rc4

Just small fixes now. The two most important are a fix for a a lock up
on USB ID pin change during system suspend/resume on dwc3 and a
use-after-free fix in ffs_fs_kill_sb().

Apart from that, some DT compatible fixes.

      Revert "typec: tcpm: Only request matching pdos" · 6f566af3
      Hans de Goede authored 
      Commit 57e6f0d7 ("typec: tcpm: Only request matching pdos") is causing
a regression, before this commit e.g. the GPD win and GPD pocket devices
were charging at 9V 3A with a PD charger, now they are instead slowly
discharging  at 5V 0.4A, as this commit causes the ports max_snk_mv/ma/mw
settings to be completely ignored.

Arguably the way to fix this would be to add a PDO_VAR() describing the
voltage range to the snk_caps of boards which can handle any voltage in
their range, but the "typec: tcpm: Only request matching pdos" commit
looks at the type of PDO advertised by the source/charger and if that
is fixed (as it typically is) only compairs against PDO_FIXED entries
in the snk_caps so supporting a range of voltage would require adding a
PDO_FIXED entry for *every possible* voltage to snk_caps.

AFAICT there is no reason why a fixed source_cap cannot be matched against
a variable snk_cap, so at a minimum the commit should be rewritten to
support that.

For now lets revert the "typec: tcpm: Only request matching pdos" commit,
fixing the regression.

      usb: quirks: add control message delay for 1b1c:1b20 · cb88a058
      Danilo Krummrich authored 
      Corsair Strafe RGB keyboard does not respond to usb control messages
sometimes and hence generates timeouts.

Commit de3af5bf ("usb: quirks: add delay init quirk for Corsair
Strafe RGB keyboard") tried to fix those timeouts by adding
USB_QUIRK_DELAY_INIT.

Unfortunately, even with this quirk timeouts of usb_control_msg()
can still be seen, but with a lower frequency (approx. 1 out of 15):

[   29.103520] usb 1-8: string descriptor 0 read error: -110
[   34.363097] usb 1-8: can't set config #1, error -110

Adding further delays to different locations where usb control
messages are issued just moves the timeouts to other locations,
e.g.:

[   35.400533] usbhid 1-8:1.0: can't add hid device: -110
[   35.401014] usbhid: probe of 1-8:1.0 failed with error -110

The only way to reliably avoid those issues is having a pause after
each usb control message. In approx. 200 boot cycles no more timeouts
were seen.

Addionaly, keep USB_QUIRK_DELAY_INIT as it turned out to be necessary
to have the delay in hub_port_connect() after hub_port_init().

The overall boot time seems not to be influenced by these additional
delays, even on fast machines and lightweight distributions.

      Pull powerpc fixes from Michael Ellerman:

 - Add handling for a missing instruction in our 32-bit BPF JIT so that

 - Add a missing NULL pointer check before a function call in new EEH
   code.

 - Fix an error path in the new ocxl driver to correctly return EFAULT.

 - The support for the new ibm,drc-info device tree property turns out
   to need several fixes, so for now we just stop advertising to
   firmware that we support it until the bugs can be ironed out.

 - One fix for the new drmem code which was incorrectly modifying the
   device tree in place.

 - Finally two fixes for the RFI flush support, so that firmware can
   advertise to us that it should be disabled entirely so as not to
   affect performance.

 "A bunch of fixes for rc3:

  Exynos:
   - fixes for using monotonic timestamps
   - register definitions
   - removal of unused file

  ipu-v3L
   - minor changes
   - make some register arrays const+static
   - fix some leaks

  meson:
   - fix for vsync

  atomic:
   - fix for memory leak

  EDID parser:
   - add quirks for some more non-desktop devices
   - 6-bit panel fix.

  drm_mm:
   - fix a bug in the core drm mm hole handling

  cirrus:
   - fix lut loading regression

  Lastly there is a deadlock fix around runtime suspend for secondary
  GPUs.

  There was a deadlock between one thread trying to wait for a workqueue
  job to finish in the runtime suspend path, and the workqueue job it
  was waiting for in turn waiting for a runtime_get_sync to return.

  The fixes avoids it by not doing the runtime sync in the workqueue as
  then we always wait for all those tasks to complete before we runtime
  suspend"

      net_sched: gen_estimator: fix broken estimators based on percpu stats · a5f7add3
      Eric Dumazet authored 
      pfifo_fast got percpu stats lately, uncovering a bug I introduced last
year in linux-4.10.

I missed the fact that we have to clear our temporary storage
before calling __gnet_stats_copy_basic() in the case of percpu stats.

Without this fix, rate estimators (tc qd replace dev xxx root est 1sec
4sec pfifo_fast) are utterly broken.

Fixes: 1c0d32fd ("net_sched: gen_estimator: complete rewrite of rate estimators")

      gianfar: simplify FCS handling and fix memory leak · d903ec77
      Andy Spencer authored 
      Previously, buffer descriptors containing only the frame check sequence
(FCS) were skipped and not added to the skb. However, the page reference
count was still incremented, leading to a memory leak.

Fixing this inside gfar_add_rx_frag() is difficult due to reserved
memory handling and page reuse. Instead, move the FCS handling to
gfar_process_frame() and trim off the FCS before passing the skb up the
networking stack.

      ipv6 sit: work around bogus gcc-8 -Wrestrict warning · ca79bec2
      Arnd Bergmann authored 
      gcc-8 has a new warning that detects overlapping input and output arguments
in memcpy(). It triggers for sit_init_net() calling ipip6_tunnel_clone_6rd(),
which is actually correct:

net/ipv6/sit.c: In function 'sit_init_net':
net/ipv6/sit.c:192:3: error: 'memcpy' source argument is the same as destination [-Werror=restrict]

The problem here is that the logic detecting the memcpy() arguments finds them
to be the same, but the conditional that tests for the input and output of
ipip6_tunnel_clone_6rd() to be identical is not a compile-time constant.

We know that netdev_priv(t->dev) is the same as t for a tunnel device,
and comparing "dev" directly here lets the compiler figure out as well
that 'dev == sitn->fb_tunnel_dev' when called from sit_init_net(), so
it no longer warns.

This code is old, so Cc stable to make sure that we don't get the warning
for older kernels built with new gcc.
