10 years agostaging: comedi: check command direction in poll() file operation
Ian Abbott [Thu, 30 Oct 2014 12:42:31 +0000 (12:42 +0000)]
staging: comedi: check command direction in poll() file operation

`comedi_poll()` handles the poll() file operation for comedi devices.

If no asynchronous command has been set up on the current "read"
subdevice, it sets the `POLLIN` and `POLLRDNORM` bits in the return
value to indicate that the read() file operation would not block as it
would return an error.  Add a check so it also does that if the
asynchronous command has been set up in the "write" direction as that
also causes the read() file operation to return an error.

Similarly, if no asynchronous command has need set up on the current
"write" subdevice, it sets the `POLLOUT` and `POLLWRNORM` bits in the
return value to indicate that the write() file operation would not block
as it would return an error.  Add a check so it also does that if the
asynchronous command has been set up in the "read" direction as that
also causes the write() file operation to return an error.

10 years agostaging: comedi: maybe force CMDF_WRITE command flag
Ian Abbott [Thu, 30 Oct 2014 12:42:26 +0000 (12:42 +0000)]
staging: comedi: maybe force CMDF_WRITE command flag

Most comedi subdevices that support asynchronous commands only support
data transfer in either the "read" or "write" direction, as indicated by
the `SDF_CMD_READ` and `SDF_CMD_WRITE` subdevice flags, although a few
support both directions on the same subdevice (though not
simultaneously).  The `struct comedi_cmd` structure passed via ioctl
call to set up the command contains a `CMDF_WRITE` flag that can be used
to choose the direction if the subdevice supports both directions, but
the flag is optional if the subdevice only supports data transfer in one
direction.

If the subdevice only supports asynchronous data transfer in a sing
direction, set the `CMDF_WRITE` flag to the correct state so that Comedi
can make use of it later.  In the case of the `COMEDI_CMDTEST` ioctl,
the updated flag will be written back to the `struct comedi_cmd` in
user-space.  In the case of the `COMEDI_CMD` ioctl, the flag only gets
written back if an error is detected while testing the command, or if
the `CMDF_BOGUS` command flag is set.  Since `__comedi_get_user_cmd()`
is called for both ioctls, that's a good place to set the flag.

 "Three main MTD fixes for 3.18:

   - A regression from 3.16 which was noticed in 3.17.  With the
     restructuring of the m25p80.c driver and the SPI NOR library
     framework, we omitted proper listing of the SPI device IDs.  This
     means m25p80.c wouldn't auto-load (modprobe) properly when built as
     a module.  For now, we duplicate the device IDs into both modules.

   - The OMAP / ELM modules were depending on an implicit link ordering.
     Use deferred probing so that the new link order (in 3.18-rc) can
     still allow for successful probing.

KVM: nVMX: Disable preemption while reading from shadow VMCS

In order to access the shadow VMCS, we need to load it. At this point,
vmx->loaded_vmcs->vmcs and the actually loaded one start to differ. If
we now get preempted by Linux, vmx_vcpu_put and, on return, the
vmx_vcpu_load will work against the wrong vmcs. That can cause
copy_shadow_to_vmcs12 to corrupt the vmcs12 state.

Fix the issue by disabling preemption during the copy operation.
copy_vmcs12_to_shadow is safe from this issue as it is executed by
vmx_vcpu_run when preemption is already disabled before vmentry.

This bug is exposed by running Jailhouse within KVM on CPUs with
shadow VMCS support.  Jailhouse never expects an interrupt pending
vmexit, but the bug can cause it if, after copy_shadow_to_vmcs12
is preempted, the active VMCS happens to have the virtual interrupt
pending flag set in the CPU-based execution controls.

   - Fix a regression in the system suspend error code path introduced
     during the 3.15 cycle that causes it to fail to take errors from
     asychronous execution of "late" suspend callbacks into account
     (Imre Deak).

   - Fix a long-standing bug in the hibernation resume error code path
     that fails to roll back everything correcty on "freeze" callback
     errors and leaves some devices in a "suspended" state causing more

x86_64, entry: Fix out of bounds read on sysenter

Rusty noticed a Really Bad Bug (tm) in my NT fix.  The entry code
reads out of bounds, causing the NT fix to be unreliable.  But, and
this is much, much worse, if your stack is somehow just below the
top of the direct map (or a hole), you read out of bounds and crash.

Excerpt from the crash:

[    1.129513] RSP: 0018:ffff88001da4bf88  EFLAGS: 00010296

  2b:*    f7 84 24 90 00 00 00     testl  $0x4000,0x90(%rsp)

That read is deterministically above the top of the stack.  I
thought I even single-stepped through this code when I wrote it to
check the offset, but I clearly screwed it up.
