Sometimes files may be created by using output from printk. As the scan
traverses the directory tree we should parse each path name and check if
it is leaking an address.
Add check for leaking address on each path name.

Currently sub routine may_leak_address() is checking regex against Perl
special variable $_ which is _fortunately_ being set correctly in a loop
before this sub routine is called. We already have declared a variable
to hold this value '$line' we should use it.
Use $line in regex match instead of implicit $_

We have git now, we don't need a version number. This was originally
added because leaking_addresses.pl shamelessly (and mindlessly) copied
checkpatch.pl

The pointers listed in /proc/1/syscall are user pointers, and negative
syscall args will show up like kernel addresses.
For example
/proc/31808/syscall: 0 0x3 0x55b107a38180 0x2000 0xffffffffffffffb0 \
0x55b107a302d0 0x55b107a38180 0x7fffa313b8e8 0x7ff098560d11
Skip parsing /proc/1/syscall

When the system is idle it is likely that most files under /proc/PID
will be identical for various processes. Scanning _all_ the PIDs under
/proc is unnecessary and implies that we are thoroughly scanning /proc.
This is _not_ the case because there may be ways userspace can trigger
creation of /proc files that leak addresses but were not present during
a scan. For these two reasons we should exclude all PID directories
under /proc except '1/'
Exclude all /proc/PID except /proc/1.

Currently we are repeatedly calling `uname -m`. This is causing the
script to take a long time to run (more than 10 seconds to parse
/proc/kallsyms). We can use Perl state variables to cache the result of
the first call to `uname -m`. With this change in place the script
scans the whole kernel in under a minute.
Cache machine architecture in state variable.

Currently script has multiple configuration arrays. This is confusing,
evident by the fact that a bunch of the entries are in the wrong place.
We can simplify the code by just having a single array for absolute
paths to skip and a single array for file names to skip wherever they
appear in the scanned directory tree. There are also currently multiple
subroutines to handle the different arrays, we can reduce these to a
single subroutine also.
Simplify the path skipping code.

Currently script parses binary files. Since we are scanning for
readable kernel addresses there is no need to parse binary files. We
can use Perl to check if file is binary and skip parsing it if so.
Do not parse binary files.

Currently script only supports x86_64 and ppc64. It would be nice to be
able to scan 32-bit machines also. We can add support for 32-bit
architectures by modifying how we check for false positives, taking
advantage of the page offset used by the kernel, and using the correct
regular expression.
Support for 32-bit machines is enabled by the observation that the kernel
addresses on 32-bit machines are larger [in value] than the page offset.
We can use this to filter false positives when scanning the kernel for
leaking addresses.
Programmatic determination of the running architecture is not
immediately obvious (current 32-bit machines return various strings from
`uname -m`). We therefore provide a flag to enable scanning of 32-bit
kernels. Also we can check the kernel config file for the offset and if
not found default to 0xc0000000. A command line option to parse in the
page offset is also provided. We do automatically detect architecture
if running on ix86.
Add support for 32-bit kernels. Add a command line option for page
offset.

Currently script uses Perl to get the machine architecture. This can be
erroneous since Perl uses the architecture of the machine that Perl was
compiled on not the architecture of the running machine. We should use
the systems `uname` command instead.

Currently script only supports 4 page table levels because of the way
the kernel address regular expression is crafted. We can do better than
this. Using previously added support for kernel configuration options we
can get the number of page table levels defined by
CONFIG_PGTABLE_LEVELS. Using this value a correct regular expression can
be crafted. This only supports 5 page tables on x86_64.
Add support for 5 page table levels on x86_64.

Currently script checks only first and last address in the vsyscall
memory range. We can do better than this. When checking for false
positives against $match, we can convert $match to a hexadecimal value
then check if it lies within the range of vsyscall addresses.

positive.

Commit 58eb5b670747 ("pstore: fix crypto dependencies") fixed up the crypto
dependencies but missed the case when no compression is selected.
With CONFIG_PSTORE=y, CONFIG_PSTORE_COMPRESS=n and CONFIG_CRYPTO=m we see
the following link error:
fs/pstore/platform.o: In function `pstore_register':
(.text+0x1b1): undefined reference to `crypto_has_alg'
(.text+0x205): undefined reference to `crypto_alloc_base'
fs/pstore/platform.o: In function `pstore_unregister':
(.text+0x3b0): undefined reference to `crypto_destroy_tfm'
Fix this by checking at compile-time if CONFIG_PSTORE_COMPRESS is enabled.

Pull SELinux updates from Paul Moore:
"A bigger than usual pull request for SELinux, 13 patches (lucky!)
along with a scary looking diffstat.
Although if you look a bit closer, excluding the usual minor
tweaks/fixes, there are really only two significant changes in this
pull request: the addition of proper SELinux access controls for SCTP
and the encapsulation of a lot of internal SELinux state.
The SCTP changes are the result of a multi-month effort (maybe even a
year or longer?) between the SELinux folks and the SCTP folks to add
proper SELinux controls. A special thanks go to Richard for seeing
this through and keeping the effort moving forward.
The state encapsulation work is a bit of janitorial work that came out
of some early work on SELinux namespacing. The question of namespacing
is still an open one, but I believe there is some real value in the
encapsulation work so we've split that out and are now sending that up
to you"

Eleven patches in total, most fall into the small fix category, but
there are three non-trivial changes worth calling out:
- the audit entry filter is being removed after deprecating it for
quite a while (years of no one really using it because it turns out
to be not very practical)
- created our own version of "__mutex_owner()" because the locking
folks were upset we were using theirs
- improved our handling of kernel command line parameters to make
them more forgiving
- we fixed auditing of symlink operations

Pull MTD updates from Boris Brezillon:
"MTD Core:
- Remove support for asynchronous erase (not implemented by any of
the existing drivers anyway)
- Remove Cyrille from the list of SPI NOR and MTD maintainers
- Fix kernel doc headers
- Allow users to define the partitions parsers they want to test
through a DT property (compatible of the partitions subnode)
- Remove the bfin-async-flash driver (the only architecture using it
has been removed)
- Fix pagetest test
- Add extra checks in mtd_erase()
- Simplify the MTD partition creation logic and get rid of
mtd_add_device_partitions()
MTD Drivers:
- Add endianness information to the physmap DT binding
- Add Eon EN29LV400A IDs to JEDEC probe logic
- Use %*ph where appropriate
SPI NOR Drivers:
- Make fsl-quaspi assign different names to MTD devices connected to
the same QSPI controller
- Remove an unneeded driver.bus assigned in the fsl-qspi driver
NAND Core:
- Prepare arrival of the SPI NAND subsystem by implementing a generic
(interface-agnostic) layer to ease manipulation of NAND devices
- Move onenand code base to the drivers/mtd/nand/ dir
- Rework timing mode selection
- Provide a generic way for NAND chip drivers to flag a specific
GET/SET FEATURE operation as supported/unsupported
- Stop embedding ONFI/JEDEC param page in nand_chip
NAND Drivers:
- Rework/cleanup of the mxc driver
- Various cleanups in the vf610 driver
- Migrate the fsmc and vf610 to ->exec_op()
- Get rid of the pxa driver (replaced by marvell_nand)
- Support ->setup_data_interface() in the GPMI driver
- Fix probe error path in several drivers
- Remove support for unused hw_syndrome mode in sunxi_nand
- Various minor improvements"

Pull device mapper updates from Mike Snitzer:
- DM core passthrough ioctl fix to retain reference to DM table, and
that table's block devices, while issuing the ioctl to one of those
block devices.
- DM core passthrough ioctl fix to _not_ override the fmode_t used to
issue the ioctl. Overriding by using the fmode_t that the block
device was originally open with during DM table load is a liability.
- Add DM core support for secure erase forwarding and update the DM
linear and DM striped targets to support them.
- A DM core 4.16 stable fix to allow abnormal IO (e.g. discard, write
same, write zeroes) for targets that make use of the non-splitting IO
variant (as is done for multipath or thinp when layered directly on
NVMe).
- Allow DM targets to return a payload in response to a DM message that
they are sent. This is useful for DM targets that would like to
provide statistics data in response to DM messages.
- Update DM bufio to support non-power-of-2 block sizes. Numerous other
related changes prepare the DM bufio code for this support.
- Fix DM crypt to use a bounded amount of memory across the entire
system. This is to avoid OOM that can otherwise occur in response to
certain pathological IO workloads (e.g. discarding a large DM crypt
device).
- Add a 'check_at_most_once' feature to the DM verity target to allow
verity to be used on mobile devices that have very limited resources.
- Fix the DM integrity target to fail early if a keyed algorithm (e.g.
HMAC) is to be used but the key isn't set.
- Add non-power-of-2 support to the DM unstripe target.
- Eliminate the use of a Variable Length Array in the DM stripe target.
- Update the DM log-writes target to record metadata (REQ_META flag).
- DM raid fixes for its nosync status and some variable range issues.

Users should get emails when the script dies because of a critical failure.
Critical failures are defined as any errors that could abnormally terminate
the script.
In order to add email support, this patch converts all die() to dodie() except:
* when '-v' is used as an option to get the version of the script.
* in Sig-Int handeler because it's not a fatal error to cancel the script.
* errors happen during parsing config

In order to enable a PLL, not only the PLL has to be powered up and
locked, but you also have to de-assert the reset signal. The last part
was missing. Add it so PLLs that were not enabled by the FW/bootloader
can be enabled from Linux.
