this is the case at least for filesystems when deciding if a process can use
the reserved 'root' blocks and for the case of things like the oom
algorithm determining if processes are root processes and should be less
likely to be killed. These types of security system requests should not be
audited or logged since they are not really security decisions. It would be
possible to solve this problem like the vm_enough_memory security check did
by creating a new LSM interface and moving all of the policy into that
interface but proves the needlessly bloat the LSM and provide complex

Capabilities: BUG when an invalid capability is requested
If an invalid (large) capability is requested the capabilities system
may panic as it is dereferencing an array of fixed (short) length. Its
possible (and actually often happens) that the capability system
accidentally stumbled into a valid memory region but it also regularly
happens that it hits invalid memory and BUGs. If such an operation does
get past cap_capable then the selinux system is sure to have problems as
it already does a (simple) validity check and BUG. This is known to
happen by the broken and buggy firegl driver.

file capabilities: add no_file_caps switch (v4)
Add a no_file_caps boot option when file capabilities are
compiled into the kernel (CONFIG_SECURITY_FILE_CAPABILITIES=y).
This allows distributions to ship a kernel with file capabilities
compiled in, without forcing users to use (and understand and
trust) them.
When no_file_caps is specified at boot, then when a process executes
a file, any file capabilities stored with that file will not be
used in the calculation of the process' new capability sets.
This means that booting with the no_file_caps boot option will
not be the same as booting a kernel with file capabilities
compiled out - in particular a task with CAP_SETPCAP will not
have any chance of passing capabilities to another task (which
isn't "really" possible anyway, and which may soon by killed
altogether by David Howells in any case), and it will instead
be able to put new capabilities in its pI. However since fI
will always be empty and pI is masked with fI, it gains the
task nothing.
We also support the extra prctl options, setting securebits and
dropping capabilities from the per-process bounding set.
The other remaining difference is that killpriv, task_setscheduler,
setioprio, and setnice will continue to be hooked. That will
be noticable in the case where a root task changed its uid
while keeping some caps, and another task owned by the new uid
tries to change settings for the more privileged task.

libata always uses PIO for ATAPI commands when the number of bytes to

PIO transfers. Implement a horkage to skip the mod16 check and apply
it to the quantum device.

libata: Fix a potential race condition in ata_scsi_park_show()
Peter Moulder has pointed out that there is a slight chance that a
negative value might be passed to jiffies_to_msecs() in
ata_scsi_park_show(). This is fixed by saving the value of jiffies in a
local variable, thus also reducing code since the volatile variable
jiffies is accessed only once.

sata_nv: fix generic, nf2/3 detection regression
All three flavors of sata_nv's are different in how their hardreset
behaves.
* generic: Hardreset is not reliable. Link often doesn't come online
after hardreset.
* nf2/3: A little bit better - link comes online with longer debounce
timing. However, nf2/3 can't reliable wait for the first D2H
Register FIS, so it can't wait for device readiness or classify the
device after hardreset. Follow-up SRST required.
* ck804: Hardreset finally works.
The core layer change to prefer hardreset and follow up changes
exposed the above issues and caused various detection regressions for
all three flavors. This patch, hopefully, fixes all the known issues
and should make sata_nv error handling more reliable.

Promise ATA engines need to be reset when errors occur.
That's currently done for errors detected by sata_promise itself,
but it's not done for errors like timeouts detected outside of
the low-level driver.
The effect of this omission is that a timeout tends to result
in a sequence of failed COMRESETs after which libata EH gives
up and disables the port. At that point the port's ATA engine
hangs and even reloading the driver will not resume it.
To fix this, make sata_promise override ->hardreset on SATA
ports with code which calls pdc_reset_port() on the port in
question before calling libata's hardreset. PATA ports don't
use ->hardreset, so for those we override ->softreset instead.

The current code read nothing but zeros on big-endian (wrong part of the

issue did not cause the system to crash, the performance is significantly
better with the fix so I view it as critical bug fix.

The mv643xx_eth mii bus implementation uses wait_event_timeout() to
wait for SMI completion interrupts.
If wait_event_timeout() would return zero, mv643xx_eth would conclude
that the SMI access timed out, but this is not necessarily true --
wait_event_timeout() can also return zero in the case where the SMI
completion interrupt did happen in time but where it took longer than
the requested timeout for the process performing the SMI access to be
scheduled again. This would lead to occasional SMI access timeouts
when the system would be under heavy load.
The fix is to ignore the return value of wait_event_timeout(), and
to re-check the SMI done bit after wait_event_timeout() returns to
determine whether or not the SMI access timed out.

ftrace: use kretprobe trampoline name to test in output
Impact: ia64+tracing build fix
When a function is kprobed, the return address is set to the
kprobe_trampoline, or something similar. This caused the output
of the trace to look confusing when the parent seemed to be this
"kprobe_trampoline" function.
To fix this, Abhishek Sagar added a test of the instruction pointer
of the parent to see if it matched the kprobe_trampoline. If it
did, the output would print a "[unknown/kretprobe'd]" instead.
Unfortunately, not all archs do this the same way, and the trampoline
function may not be exported, which causes failures in builds.
This patch will compare the name instead of the pointer to see
if it matches. This prevents us from depending on a function from
being exported, and should work on all archs. The worst that can
happen is that an arch might use a different name and then we
go back to the confusing output. At least the arch will still build.
