Rob Clark 6ddd388ab2 drm/atomic: track bitmask of planes attached to crtc
Chasing plane->state->crtc of planes that are *not* part of the same
atomic update is racy, making it incredibly awkward (or impossible) to
do something simple like iterate over all planes and figure out which
ones are attached to a crtc.

Solve this by adding a bitmask of currently attached planes in the
crtc-state.

Note that the transitional helpers do not maintain the plane_mask.  But
they only support the legacy ioctls, which have sufficient brute-force
locking around plane updates that they can continue to loop over all
planes to see what is attached to a crtc the old way.

Signed-off-by: Rob Clark <robdclark@gmail.com>
[danvet:
- Drop comments about locking in set_crtc_for_plane since they're a
  bit misleading - we already should hold lock for the current crtc.
- Also WARN_ON if get_state on the old crtc fails since that should
  have been done already.
- Squash in fixup to check get_plane_state return value, reported by
  Dan Carpenter and acked by Rob Clark.]

Willem de Bruijn f4713a3dfa net-timestamp: make tcp_recvmsg call ipv6_recv_error for AF_INET6 socks
TCP timestamping introduced MSG_ERRQUEUE handling for TCP sockets.
If the socket is of family AF_INET6, call ipv6_recv_error instead
of ip_recv_error.

This change is more complex than a single branch due to the loadable
ipv6 module. It reuses a pre-existing indirect function call from
ping. The ping code is safe to call, because it is part of the core
ipv6 module and always present when AF_INET6 sockets are active.

Fixes: 4ed2d765 (net-timestamp: TCP timestamping)
Signed-off-by: Willem de Bruijn <willemb@google.com>

It may also be worthwhile to add WARN_ON_ONCE(sk->family == AF_INET6)
to ip_recv_error.

Greg Kroah-Hartman 8bb9b9a006 Third set of IIO fixes for the 3.18 cycle.
Most of these are fairly standard little fixes, a bmc150 and bmg160 patch
 is to make an ABI change to indicated a specific axis in an event rather
 than the generic option in the original drivers.  As both of these drivers
 are new in this cycle it would be ideal to push this minor change through
 even though it isn't strictly a fix.  A couple of other 'fixes' change
 defaults for some settings on these new drivers to more intuitive calues.
 Looks like some useful feedback has been coming in for this driver
 since it was applied.
 
 * IIO_EVENT_CODE_EXTRACT_DIR bit mask was wrong and has been for a while
   0xCF clearly doesn't give a contiguous bitmask.
 * kxcjk-1013 range setting was failing to mask out the previous value
   in the register and hence was 'enable only'.
 * men_z188 device id table wasn't null terminated.
 * bmg160 and bmc150 both failed to correctly handling an error in mode
   setting.
 * bmg160 and bmc150 both had a bug in setting the event direction in the
   event spec (leads to an attribute name being incorrect)
 * bmg160 defaulted to an open drain output for the interrupt - as a default
   this obviously only works with some interrupt chips - hence change the
   default to push-pull (note this is a new driver so we aren't going to
   cause any regressions with this change).
 * bmc150 had an unintuitive default for the rate of change (motion detector)
   so change it to 0 (new driver so change of default won't cause any
   regressions).

Lars-Peter Clausen 18df89fef2 drm: Decouple EDID parsing from I2C adapter
The drm_get_edid() function performs direct I2C accesses to read EDID
blocks, assuming that the monitor DDC interface is directly connected to
the I2C bus. It can't thus be used with HDMI encoders that control the
DDC bus and expose EDID blocks through a different interface.

Refactor drm_do_get_edid() to take a block read callback function
instead of an I2C adapter, and export it for direct use by drivers.

As in the general case the DDC bus is accessible by the kernel at the
I2C level, drivers must make all reasonable efforts to expose it as an
I2C adapter and use drm_get_edid() instead of abusing this function.

Ard Biesheuvel d3fccc7ef8 kvm: fix kvm_is_mmio_pfn() and rename to kvm_is_reserved_pfn()
This reverts commit 85c8555ff0 ("KVM: check for !is_zero_pfn() in
kvm_is_mmio_pfn()") and renames the function to kvm_is_reserved_pfn.

The problem being addressed by the patch above was that some ARM code
based the memory mapping attributes of a pfn on the return value of
kvm_is_mmio_pfn(), whose name indeed suggests that such pfns should
be mapped as device memory.

However, kvm_is_mmio_pfn() doesn't do quite what it says on the tin,
and the existing non-ARM users were already using it in a way which
suggests that its name should probably have been 'kvm_is_reserved_pfn'
from the beginning, e.g., whether or not to call get_page/put_page on
it etc. This means that returning false for the zero page is a mistake
and the patch above should be reverted.

 "This series fix a nasty issue with radeon adapters on powerpc servers,
  it's all CC'ed stable and has the relevant maintainers ack's/reviews.

  Basically, some (radeon) adapters have issues with MSI addresses above
  1T (only support 40-bits).  We had powerpc specific quirk but it only
  listed a specific revision of an adapter that we shipped with our
  machines and didn't properly handle the audio function which some
  distros enable nowadays.

  So we made the quirk generic and fixed both the graphic and audio
  drivers properly to use it.

  Without that, ppc64 server machines will crash at boot with a radeon
  adapter.

  Note: This has been brewing for a while, it just needed a last respin
  which got delayed due to us moving ozlabs to a new location in town
  and other such things taking priority"

2014-11-23 11:33:49 -08:00
Tejun Heo 4aab3b5b3c percpu-ref: fix DEAD flag contamination of percpu pointer
While decoupling ATOMIC and DEAD flags, f47ad45784 ("percpu_ref:
decouple switching to percpu mode and reinit") updated
__ref_is_percpu() so that it only tests ATOMIC flag to determine
whether the ref is in percpu mode or not; however, while DEAD implies
ATOMIC, the two flags are set separately during percpu_ref_kill() and
if __ref_is_percpu() races percpu_ref_kill(), it may see DEAD w/o
ATOMIC.  Because __ref_is_percpu() returns @ref->percpu_count_ptr
value verbatim as the percpu pointer after testing ATOMIC, the pointer
may now be contaminated with the DEAD flag.

This can be fixed by clearing the flag bits before returning the
pointer which was the fix proposed by Shaohua; however, as DEAD
implies ATOMIC, we can just test for both flags at once and avoid the
explicit masking.

Update __ref_is_percpu() so that it tests that both ATOMIC and DEAD
are clear before returning @ref->percpu_count_ptr as the percpu
pointer.

Daniel Vetter 3758b34193 drm: s/enum_blob_list/enum_list/ in drm_property
I guess for hysterical raisins this was meant to be the way to read
blob properties. But that's done with the two-stage approach which
uses separate blob kms object and the special-purpose get_blob ioctl.

Shipping userspace seems to have never relied on this, and the kernel
also never put any blob thing onto that property. And nowadays it
would blow up, e.g. in drm_property_destroy. Also it makes no sense to
return values in an ioctl that only returns metadata about everything.

So let's ditch all the internal code for the blob list, rename the
list to be unambiguous and sprinkle comments all over the place to
explain this peculiar piece of api.

v2: Squash in fixup from Rob to remove now unused variables.

Yet another fallout from not considering DP MST hotplug. With the
previous patches we have stable indices, but it might still happen
that a connector gets added between when we allocate the array and
when we actually add a connector. Especially when we back off due to
ww mutex contention or similar issues.

So store the sizes of the arrays in struct drm_atomic_state and double
check them. We don't really care about races except that we want to
use a consistent value, so ACCESS_ONCE is all we need. And if we
indeed notice that we'd overrun the array then just give up and
restart the entire ioctl.

Marc Kleine-Budde says:

====================
pull-request: can 2014-11-18

this is a pull request of 17 patches for net/master for the v3.18 release
cycle.

The last patch of this pull request ("can: m_can: update to support CAN FD
features") adds, as the description says, a new feature to the m_can driver. As
the m_can driver has been added in v3.18 there is no risk of causing a
regression. Give me a note if this is not okay and I'll create a new pull
request without it.

There is a patch for the CAN infrastructure by Thomas Körper which fixes
calling kfree_skb() from interrupt context. Roman Fietze fixes a typo also in
the infrastructure. A patch by Dong Aisheng adds a generic helper function to
tell if a skb is normal CAN or CAN-FD frame. Alexey Khoroshilov of the Linux
Driver Verification project fixes a memory leak in the esd_usb2 driver. Two
patches by Sudip Mukherjee remove unused variables and fixe the signess of a
variable. Three patches by me add the missing .ndo_change_mtu callback to the
xilinx_can, rcar_can and gs_usb driver.

The remaining patches improve the m_can driver: David Cohen adds the missing
CONFIG_HAS_IOMEM dependency. Dong Aisheng provides 6 bugfix patches (most
important: missing RAM init, sleep in NAPI poll, dlc in RTR). While the last of
his patches adds CAN FD support to the driver.

James Hogan e6d5e7d90b clk-divider: Fix READ_ONLY when divider > 1
Commit 79c6ab5095 (clk: divider: add CLK_DIVIDER_READ_ONLY flag) in
v3.16 introduced the CLK_DIVIDER_READ_ONLY flag which caused the
recalc_rate() and round_rate() clock callbacks to be omitted.

However using this flag has the unfortunate side effect of causing the
clock recalculation code when a clock rate change is attempted to always
treat it as a pass-through clock, i.e. with a fixed divide of 1, which
may not be the case. Child clock rates are then recalculated using the
wrong parent rate.

Therefore instead of dropping the recalc_rate() and round_rate()
callbacks, alter clk_divider_bestdiv() to always report the current
divider as the best divider so that it is never altered.

For me the read only clock was the system clock, which divided the PLL
rate by 2, from which both the UART and the SPI clocks were divided.
Initial setting of the UART rate set it correctly, but when the SPI
clock was set, the other child clocks were miscalculated. The UART clock
was recalculated using the PLL rate as the parent rate, resulting in a
UART new_rate of double what it should be, and a UART which spewed forth

Georgi Djakov 9a6cb70f40 clk: qcom: Fix duplicate rbcpr clock name
There is a duplication in a clock name for apq8084 platform that causes
the following warning: "RBCPR_CLK_SRC" redefined

Resolve this by adding a MMSS_ prefix to this clock and making its name
coherent with msm8974 platform.

====================
Netfilter/IPVS fixes for net

The following patchset contains Netfilter updates for your net tree,
they are:

1) Fix missing initialization of the range structure (allocated in the
   stack) in nft_masq_{ipv4, ipv6}_eval, from Daniel Borkmann.

2) Make sure the data we receive from userspace contains the req_version
   structure, otherwise return an error incomplete on truncated input.
   From Dan Carpenter.

3) Fix handling og skb->sk which may cause incorrect handling
   of connections from a local process. Via Simon Horman, patch from
   Calvin Owens.

4) Fix wrong netns in nft_compat when setting target and match params
   structure.

5) Relax chain type validation in nft_compat that was recently included,
   this broke the matches that need to be run from the route chain type.
   Now iptables-test.py automated regression tests report success again
   and we avoid the only possible problematic case, which is the use of
   nat targets out of nat chain type.

6) Use match->table to validate the tablename, instead of the match->name.
   Again patch for nft_compat.

7) Restore the synchronous release of objects from the commit and abort
   path in nf_tables. This is causing two major problems: splats when using
   nft_compat, given that matches and targets may sleep and call_rcu is
   invoked from softirq context. Moreover Patrick reported possible event
   notification reordering when rules refer to anonymous sets.

8) Fix race condition in between packets that are being confirmed by
   conntrack and the ctnetlink flush operation. This happens since the
   removal of the central spinlock. Thanks to Jesper D. Brouer to looking
   into this.

Peter Zijlstra 23cfa361f3 sched/cputime: Fix cpu_timer_sample_group() double accounting
While looking over the cpu-timer code I found that we appear to add
the delta for the calling task twice, through:

  cpu_timer_sample_group()
    thread_group_cputimer()
      thread_group_cputime()
        times->sum_exec_runtime += task_sched_runtime();

    *sample = cputime.sum_exec_runtime + task_delta_exec();

Which would make the sample run ahead, making the sleep short.

Maxime COQUELIN 00b4d9a141 bitops: Fix shift overflow in GENMASK macros
On some 32 bits architectures, including x86, GENMASK(31, 0) returns 0
instead of the expected ~0UL.

This is the same on some 64 bits architectures with GENMASK_ULL(63, 0).

This is due to an overflow in the shift operand, 1 << 32 for GENMASK,
1 << 64 for GENMASK_ULL.

Dave Airlie ca5a71de48 drm: Sanitize DRM_IOCTL_MODE_CREATE_DUMB input
Some drivers erroneously treat the .pitch and .size fields of struct
 drm_mode_create_dumb as inputs. While the include/uapi/drm/drm_mode.h
 header has a comment denoting them as outputs, that seemingly wasn't
 enough to make drivers use them properly.
 
 The result is that some userspace doesn't explicitly zero out those
 fields, assuming that the kernel won't use them. That causes problems
 since the data within the structure might be uninitialized, so bogus
 data may end up confusing drivers (ridiculously large values for the
 pitch, ...).
 
 This series attempts to improve the situation by fixing all drivers to
 not use the output fields. Furthermore to spare new drivers this bad
 surprise, the DRM core now zeros out these fields prior to handing the
 data structure to the driver.
 
 Lessons learned from this are that future IOCTLs should be properly
 documented (in the DRM DocBook for example) and should be rigorously
 defined. To prevent misuse like this, userspace should be required to
 zero out all output fields. The kernel should check for this and fail
 if that's not the case.

Dave Airlie b0654103f5 drm/tegra: Changes for v3.19-rc1
The highlights in this pull request are:
 
   * IOMMU support: The Tegra DRM driver can now deal with discontiguous
     buffers if an IOMMU exists in the system. That means it can allocate
     using drm_gem_get_pages() and will map them into IOVA space via the
     IOMMU API. Similarly, non-contiguous PRIME buffers can be imported
     from a different driver, which allows better integration with gk20a
     (nouveau) and less hacks.
 
   * Universal planes: This is precursory work for atomic modesetting and
     will allow hardware cursor support to be implemented on pre-Tegra114
     where RGB cursors were not supported.
 
   * DSI ganged-mode support: The DSI controller can now gang up with a
     second DSI controller to drive high resolution DSI panels.
 
 Besides those bigger changes there is a slew of fixes, cleanups, plugged
 memory leaks and so on.

drm/tegra: Changes for v3.19-rc1

The highlights in this pull request are:

  * IOMMU support: The Tegra DRM driver can now deal with discontiguous
    buffers if an IOMMU exists in the system. That means it can allocate
    using drm_gem_get_pages() and will map them into IOVA space via the
    IOMMU API. Similarly, non-contiguous PRIME buffers can be imported
    from a different driver, which allows better integration with gk20a
    (nouveau) and less hacks.

  * Universal planes: This is precursory work for atomic modesetting and
    will allow hardware cursor support to be implemented on pre-Tegra114
    where RGB cursors were not supported.

  * DSI ganged-mode support: The DSI controller can now gang up with a
    second DSI controller to drive high resolution DSI panels.

Besides those bigger changes there is a slew of fixes, cleanups, plugged
memory leaks and so on.
