9 years agostaging: comedi: use CAP_SYS_ADMIN instead of CAP_NET_ADMIN

staging: comedi: use CAP_SYS_ADMIN instead of CAP_NET_ADMIN

If the "comedi" module has been loaded with the
"comedi_num_legacy_minors" module parameter set to a non-zero value,
some reserved comedi devices get created.  These can be attached to a
low-level comedi driver using the `COMEDI_DEVCONFIG` ioctl command,
which checks for the `CAP_SYS_ADMIN` capability.  Of course, the comedi
device needs to be opened before the ioctl command can be sent.  If the
comedi device is unattached, `comedi_open()` currently requires the
`CAP_NET_ADMIN` capability.  It makes more sense to just require the
`CAP_SYS_ADMIN` capability here, so change it.

For the curious, commit a8f80e8ff94e ("Networking: use CAP_NET_ADMIN
when deciding to call request_module") changed this capability from
`CAP_SYS_MODULE` to `CAP_NET_ADMIN`, even though it doesn't seem
relevant here.  The original `CAP_SYS_MODULE` capability was due to the
function having some code to request a module using a "char-major-%i-%i"
alias, but that was never compiled in and was removed by commit
f30f2c2d417b ("staging: comedi: remove check for CONFIG_KMOD").

staging: comedi: cb_pcimdas: add external analog output ranges

The analog output range is not programmable, but the ranges for each of
the two analog output channels are settable via jumpers.  These jumper
settings are not readable by the driver.  The driver
provides a range table containing all the possible internal ranges
(+/-10V, +/-5V, 0-10V, 0-5V) to provide information to the user
application (although any range selected by the application that differs
from the jumper settings will not produce the expected voltage output).

The range table does not cover all possible ranges of the analog output
channels.  The jumpers also allow an external reference voltage between
0 and 10V to be used as bipolar or unipolar output range.  Add a couple
more ranges to the end of the range table to define these two external
ranges.

staging/lustre: remove alloc_fail_rate sysctl

It was used to control allocation failure rate, but there is
in-kernel way of doing that that's more versatile too.

This is going to remove just the sysctl, the underlying variable
will be removed once all OBD_ALLOC* macros removal patchseries land.

bluetooth: fix list handling

Commit 835a6a2f8603 ("Bluetooth: Stop sabotaging list poisoning")
thought that the code was sabotaging the list poisoning when NULL'ing
out the list pointers and removed it.

But what was going on was that the bluetooth code was using NULL
pointers for the list as a way to mark it empty, and that commit just
broke it (and replaced the test with NULL with a "list_empty()" test on
a uninitialized list instead, breaking things even further).

So fix it all up to use the regular and real list_empty() handling
(which does not use NULL, but a pointer to itself), also making sure to
initialize the list properly (the previous NULL case was initialized
implicitly by the session being allocated with kzalloc())

This is a combination of patches by Marcel Holtmann and Tedd Ho-Jeong
An.

[ I would normally expect to get this through the bt tree, but I'm going

9p: cope with bogus responses from server in p9_client_{read,write}

if server claims to have written/read more than we'd told it to,
warn and cap the claimed byte count to avoid advancing more than
we are ready to.
