Disable the new dtc warnings by default as there are 1000s. As before, warnings are enabled with W=1 or W=2.

kcov: allow more fine-grained coverage instrumentation
For more targeted fuzzing, it's better to disable kernel-wide
instrumentation and instead enable it on a per-subsystem basis. This
follows the pattern of UBSAN and allows you to compile in the kcov
driver without instrumenting the whole kernel.
To instrument a part of the kernel, you can use either
# for a single file in the current directory
KCOV_INSTRUMENT_filename.o := y
or
# for all the files in the current directory (excluding subdirectories)
KCOV_INSTRUMENT := y
or
# (same as above)
ccflags-y += $(CFLAGS_KCOV)
or
# for all the files in the current directory (including subdirectories)
subdir-ccflags-y += $(CFLAGS_KCOV)

Kbuild: don't add obj tree in additional includes
When building with separate object directories and driver specific Makefiles that add additional header include paths, Kbuild adjusts the gcc flags so that we include both the directory in the source tree and in the object tree. However, due to another bug I fixed earlier, this did not actually include the correct directory in the object tree, so we know that we only really need the source tree here. Also, including the object tree sometimes causes warnings about nonexisting directories when the include path only exists in the source. This changes the logic to only emit the -I argument for the srctree, not for objects. We still need both $(srctree)/$(src) and $(obj) though, so I'm adding them manually.

kernel: add kcov code coverage
kcov provides code coverage collection for coverage-guided fuzzing (randomized testing). Coverage-guided fuzzing is a testing technique that uses coverage feedback to determine new interesting inputs to a system. A notable user-space example is AFL (http://lcamtuf.coredump.cx/afl/). However, this technique is not widely used for kernel testing due to missing compiler and kernel support. kcov does not aim to collect as much coverage as possible. It aims to collect more or less stable coverage that is function of syscall inputs. To achieve this goal it does not collect coverage in soft/hard interrupts and instrumentation of some inherently non-deterministic or non-interesting parts of kernel is disbled (e.g. scheduler, locking). Currently there is a single coverage collection mode (tracing), but the API anticipates additional collection modes. Initially I also implemented a second mode which exposes coverage in a fixed-size hash table of counters (what Quentin used in his original patch). I've dropped the second mode for simplicity. This patch adds the necessary support on kernel side. The complimentary compiler support was added in gcc revision 231296. We've used this support to build syzkaller system call fuzzer, which has found 90 kernel bugs in just 2 months: https://github.com/google/syzkaller/wiki/Found-Bugs We've also found 30+ bugs in our internal systems with syzkaller. Another (yet unexplored) direction where kcov coverage would greatly help is more traditional "blob mutation". For example, mounting a random blob as a filesystem, or receiving a random blob over wire. Why not gcov. Typical fuzzing loop looks as follows: (1) reset coverage, (2) execute a bit of code, (3) collect coverage, repeat. A typical coverage can be just a dozen of basic blocks (e.g. an invalid input). In such context gcov becomes prohibitively expensive as reset/collect coverage steps depend on total number of basic blocks/edges in program (in case of kernel it is about 2M). Cost of kcov depends only on number of executed basic blocks/edges. On top of that, kernel requires per-thread coverage because there are always background threads and unrelated processes that also produce coverage. With inlined gcov instrumentation per-thread coverage is not possible. kcov exposes kernel PCs and control flow to user-space which is insecure. But debugfs should not be mapped as user accessible. Based on a patch by Quentin Casasnovas.

UBSAN: run-time undefined behavior sanity checker
UBSAN uses compile-time instrumentation to catch undefined behavior (UB). Compiler inserts code that perform certain kinds of checks before operations that could cause UB. If check fails (i.e. UB detected) __ubsan_handle_* function called to print error message. So the most of the work is done by compiler. This patch just implements ubsan handlers printing errors. GCC has this capability since 4.9.x [1] (see -fsanitize=undefined option and its suboptions). However GCC 5.x has more checkers implemented [2]. Article [3] has a bit more details about UBSAN in the GCC.

kasan: add kernel address sanitizer infrastructure
Kernel Address sanitizer (KASan) is a dynamic memory error detector. It
provides fast and comprehensive solution for finding use-after-free and
out-of-bounds bugs.
KASAN uses compile-time instrumentation for checking every memory access,
therefore GCC > v4.9.2 required. v4.9.2 almost works, but has issues with
putting symbol aliases into the wrong section, which breaks kasan
instrumentation of globals.
This patch only adds infrastructure for kernel address sanitizer. It's
not available for use yet. The idea and some code was borrowed from [1].
Basic idea:
The main idea of KASAN is to use shadow memory to record whether each byte
of memory is safe to access or not, and use compiler's instrumentation to
check the shadow memory on each memory access.
Address sanitizer uses 1/8 of the memory addressable in kernel for shadow
memory and uses direct mapping with a scale and offset to translate a
memory address to its corresponding shadow address.
Here is function to translate address to corresponding shadow address:
unsigned long kasan_mem_to_shadow(unsigned long addr)
{
return (addr >> KASAN_SHADOW_SCALE_SHIFT) + KASAN_SHADOW_OFFSET;
}
where KASAN_SHADOW_SCALE_SHIFT = 3.
So for every 8 bytes there is one corresponding byte of shadow memory.
The following encoding used for each shadow byte: 0 means that all 8 bytes
of the corresponding memory region are valid for access; k (1 <= k <= 7)
means that the first k bytes are valid for access, and other (8 - k) bytes
are not; Any negative value indicates that the entire 8-bytes are
inaccessible. Different negative values used to distinguish between
different kinds of inaccessible memory (redzones, freed memory) (see
mm/kasan/kasan.h).
To be able to detect accesses to bad memory we need a special compiler.
Such compiler inserts a specific function calls (__asan_load*(addr),
__asan_store*(addr)) before each memory access of size 1, 2, 4, 8 or 16.
These functions check whether memory region is valid to access or not by
checking corresponding shadow memory. If access is not valid an error
printed.
Historical background of the address sanitizer from Dmitry Vyukov:
"We've developed the set of tools, AddressSanitizer (Asan),
ThreadSanitizer and MemorySanitizer, for user space. We actively use
them for testing inside of Google (continuous testing, fuzzing,
running prod services). To date the tools have found more than 10'000
scary bugs in Chromium, Google internal codebase and various
open-source projects (Firefox, OpenSSL, gcc, clang, ffmpeg, MySQL and
lots of others): [2] [3] [4].
The tools are part of both gcc and clang compilers.
We have not yet done massive testing under the Kernel AddressSanitizer
(it's kind of chicken and egg problem, you need it to be upstream to
start applying it extensively). To date it has found about 50 bugs.
Bugs that we've found in upstream kernel are listed in [5].
We've also found ~20 bugs in out internal version of the kernel. Also
people from Samsung and Oracle have found some.
[...]
As others noted, the main feature of AddressSanitizer is its
performance due to inline compiler instrumentation and simple linear
shadow memory. User-space Asan has ~2x slowdown on computational
programs and ~2x memory consumption increase. Taking into account that
kernel usually consumes only small fraction of CPU and memory when
running real user-space programs, I would expect that kernel Asan will
have ~10-30% slowdown and similar memory consumption increase (when we
finish all tuning).
I agree that Asan can well replace kmemcheck. We have plans to start
working on Kernel MemorySanitizer that finds uses of unitialized
memory. Asan+Msan will provide feature-parity with kmemcheck. As
others noted, Asan will unlikely replace debug slab and pagealloc that
can be enabled at runtime. Asan uses compiler instrumentation, so even
if it is disabled, it still incurs visible overheads.
Asan technology is easily portable to other architectures. Compiler
instrumentation is fully portable. Runtime has some arch-dependent
parts like shadow mapping and atomic operation interception. They are
relatively easy to port."
Comparison with other debugging features:
========================================
KMEMCHECK:
- KASan can do almost everything that kmemcheck can. KASan uses
compile-time instrumentation, which makes it significantly faster than
kmemcheck. The only advantage of kmemcheck over KASan is detection of
uninitialized memory reads.
Some brief performance testing showed that kasan could be
x500-x600 times faster than kmemcheck:
$ netperf -l 30
MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to localhost (127.0.0.1) port 0 AF_INET
Recv Send Send
Socket Socket Message Elapsed
Size Size Size Time Throughput
bytes bytes bytes secs. 10^6bits/sec
no debug: 87380 16384 16384 30.00 41624.72
kasan inline: 87380 16384 16384 30.00 12870.54
kasan outline: 87380 16384 16384 30.00 10586.39
kmemcheck: 87380 16384 16384 30.03 20.23
- Also kmemcheck couldn't work on several CPUs. It always sets
number of CPUs to 1. KASan doesn't have such limitation.
DEBUG_PAGEALLOC:
- KASan is slower than DEBUG_PAGEALLOC, but KASan works on sub-page
granularity level, so it able to find more bugs.
SLUB_DEBUG (poisoning, redzones):
- SLUB_DEBUG has lower overhead than KASan.
- SLUB_DEBUG in most cases are not able to detect bad reads,
KASan able to detect both reads and writes.
- In some cases (e.g. redzone overwritten) SLUB_DEBUG detect
bugs only on allocation/freeing of object. KASan catch
bugs right before it will happen, so we always know exact
place of first bad read/write.

dts, kbuild: Factor out dtbs install rules to Makefile.dtbinst
Move dtbs install rules to Makefile.dtbinst. This change is needed to implement support for dts vendor subdirs. The change makes Makefiles easier and smaller as no longer the dtbs_install rule needs to be defined. Another advantage is that install goals are not encoded in targets anymore (%.dtb_dtbinst_).

kbuild: handle multi-objs dependency appropriately
The comment in scripts/Makefile.build says as follows:
We would rather have a list of rules like
foo.o: $(foo-objs)
but that's not so easy, so we rather make all composite objects depend
on the set of all their parts
This commit makes it possible!
For example, assume a Makefile like this
obj-m = foo.o bar.o
foo-objs := foo1.o foo2.o
bar-objs := bar1.o bar2.o
Without this patch, foo.o depends on all of
foo1.o foo2.o bar1.o bar2.o.
It looks funny that foo.o is regenerated when bar1.c is updated.
Now we can handle the dependency of foo.o and bar.o separately.

kbuild: dtbs_install: new make target
Unlike other build products in the Linux kernel, there is no 'make
*install' mechanism to put devicetree blobs in a standard place.
This commit adds a new 'dtbs_install' make target which copies all of
the dtbs into the INSTALL_DTBS_PATH directory. INSTALL_DTBS_PATH can be
set before calling make to change the default install directory. If not
set then it defaults to:
$INSTALL_PATH/dtbs/$KERNELRELEASE.
This is done to keep dtbs from different kernel versions separate until
things have settled down. Once the dtbs are stable, and not so strongly
linked to the kernel version, the devicetree files will most likely move
to their own repo. Users will need to upgrade install scripts at that
time.
v7: (reworked by Grant Likely)
- Moved rules from arch/arm/Makefile to arch/arm/boot/dts/Makefile so
that each dtb install could have a separate target and be reported as
part of the make output.
- Fixed dependency problem to ensure $KERNELRELEASE is calculated before
attempting to install
- Removed option to call external script. Copying the files should be
sufficient and a build system can post-process the install directory.
Despite the fact an external script is used for installing the kernel,
I don't think that is a pattern that should be encouraged. I would
rather see buildroot type tools post process the install directory to
rename or move dtb files after installing to a staging directory.
- Plus it is easy to add a hook after the fact without blocking the
rest of this feature.
- Move the helper targets into scripts/Makefile.lib with the rest of the
common dtb rules

of: Move testcase FDT data into drivers/of
The testcase data is usable by any platform. This patch moves it into the drivers/of directory so it can be included by any architecture. Using the test cases requires manually adding #include <testcases.dtsi> to the end of the boards .dtsi file and enabling CONFIG_OF_SELFTEST. Not pretty though. A useful project would be to make the testcase code easier to execute. Signed-off-by: Grant Likely <grant.likely@linaro.org> |

kbuild: create directory for dir/file.o
When add a obj with dir to obj-y, like this
obj-y += dir/file.o
The $(obj)/dir not created, this patch fix this.
When try to add a file(which in a subdir) to my board's obj-y, the build
progress crashed.
For example, I use at91rm9200ek board, and in kernel dir run:
mkdir objtree
make O=objtree at91rm9200_defconfig
mkdir arch/arm/mach-at91/dir
touch arch/arm/mach-at91/dir/file.c
and edit arch/arm/mach-at91/dir/file.c to add some code.
then edit arch/arm/mach-at91/Makefile, change the following line:
obj-$(CONFIG_MACH_AT91RM9200EK) += board-rm9200ek.o
to:
obj-$(CONFIG_MACH_AT91RM9200EK) += board-rm9200ek.o dir/file.o
Now build it:
make O=objtree
Then the error appears:
...
CC arch/arm/mach-at91/board-rm9200dk.o
CC arch/arm/mach-at91/board-rm9200ek.o
CC arch/arm/mach-at91/dir/file.o
linux-2.6/arch/arm/mach-at91/dir/file.c:5:
fatal error: opening dependency file
arch/arm/mach-at91/dir/.file.o.d: No such file or directory
Check the objtree:
LANG=en ls objtree/arch/arm/mach-at91/dir
ls: cannot access objtree/arch/arm/mach-at91/dir: No such file or directory
It's apparently that the target dir not created for file.o
Check kbuild source code. It seems that kbuild create dirs for that in
$(obj-dirs). But if the dir need not to create a built-in.o, It should
never in $(obj-dirs).
So I make this patch to make sure It in $(obj-dirs)

kbuild: always run gcc -E on *.dts, remove cmd_dtc_cpp
Replace cmd_dtc with cmd_dtc_cpp, and delete the latter. Previously, a special file extension (.dtsp) was required to trigger the C pre-processor to run on device tree files. This was ugly. Now that previous changes have enhanced cmd_dtc_cpp to collect dependency information from both gcc -E and dtc, we can transparently run the pre- processor on all device tree files, irrespective of whether they use /include/ or #include syntax to include *.dtsi.

kbuild: cmd_dtc_cpp: extract deps from both gcc -E and dtc
Prior to this change, when compiling *.dts to *.dtb, the dependency output from dtc would be used, and when compiling *.dtsp to *.dtb, the dependency output from gcc -E alone would be used, despite dtc also being invoked (on a temporary file that was guaranteed to have no dependencies). With this change, when compiling *.dtsp to *.dtb, the dependency files from both gcc -E and dtc are used. This will allow cmd_dtc_cpp to replace cmd_dtc in a future change. In turn, that will allow the C pre- processor to be run transparently on *.dts, without the need to a separate rule or file extension to trigger it.

kbuild: create an "include chroot" for DT bindings
The recent dtc+cpp support allows header files and C pre-processor defines/macros to be used when compiling device tree files. These headers will typically define various constants that are part of the device tree bindings. The original patch which set up the dtc+cpp include path only considered using those headers from device tree files. However, most are also useful for kernel code which needs to interpret the device tree. In both the DT files and the kernel, I'd like to include the DT-related headers in the same way, for example, <dt-bindings/gpio/tegra-gpio.h>. That will simplify any text which discusses the DT header locations. Creating a <dt-bindings/> for kernel source to use is as simple as placing files into include/dt-bindings/. However, when compiling DT files, the include path should be restricted so that only the dt-bindings path is available; arbitrary kernel headers shouldn't be exposed. For this reason, create a specific include directory for use by dtc+cpp, and symlink dt-bindings from there to the actual location of include/dt-bindings/. For want of a better location, place this "include chroot" into the existing dts/ directory. arch/*/boot/dts/include/dt-bindings -> ../../../../../include/dt-bindings Some headers used by device tree files may not be useful to the kernel; they may be used simply to aid in constructing the DT file (e.g. macros to create a node), but not define any information that the kernel needs to share. These may be placed directly into arch/*/boot/dts/ along with the DT files themselves.

CONFIG_SYMBOL_PREFIX: cleanup.
We have CONFIG_SYMBOL_PREFIX, which three archs define to the string "_". But Al Viro broke this in "consolidate cond_syscall and SYSCALL_ALIAS declarations" (in linux-next), and he's not the first to do so. Using CONFIG_SYMBOL_PREFIX is awkward, since we usually just want to prefix it so something. So various places define helpers which are defined to nothing if CONFIG_SYMBOL_PREFIX isn't set: 1) include/asm-generic/unistd.h defines __SYMBOL_PREFIX. 2) include/asm-generic/vmlinux.lds.h defines VMLINUX_SYMBOL(sym) 3) include/linux/export.h defines MODULE_SYMBOL_PREFIX. 4) include/linux/kernel.h defines SYMBOL_PREFIX (which differs from #7) 5) kernel/modsign_certificate.S defines ASM_SYMBOL(sym) 6) scripts/modpost.c defines MODULE_SYMBOL_PREFIX 7) scripts/Makefile.lib defines SYMBOL_PREFIX on the commandline if CONFIG_SYMBOL_PREFIX is set, so that we have a non-string version for pasting. (arch/h8300/include/asm/linkage.h defines SYMBOL_NAME(), too). Let's solve this properly: 1) No more generic prefix, just CONFIG_HAVE_UNDERSCORE_SYMBOL_PREFIX. 2) Make linux/export.h usable from asm. 3) Define VMLINUX_SYMBOL() and VMLINUX_SYMBOL_STR(). 4) Make everyone use them.

kbuild: limit dtc+cpp include path
Device tree source files may now include header files. The intent is that those header files define/name constants used as part of the DT bindings. Currently this feature is open to abuse, since any kernel header file at all can be included, This could allow device tree files to become dependant on kernel headers files, and thus make them no longer OS-independent. This would also prevent separating the device tree source files from the kernel repository. Solve this by limiting the cpp include path for device tree files to separate directories.

kbuild: centralize .dts->.dtb rule
All architectures that use cmd_dtc do so in almost the same way. Create a central build rule to avoid duplication. The one difference is that most current uses of dtc build $(obj)/%.dtb from $(src)/dts/%.dts rather than building the .dtb in the same directory as the .dts file. This difference will be eliminated arch-by-arch in future patches. MIPS is the exception here; it already uses the exact same rule as the new common rule, so the duplicate is removed in this patch to avoid any conflict. arch/mips changes courtesy of Ralf Baechle. Update Documentation/kbuild to remove the explicit call to cmd_dtc from the example, now that the rule exists in a centralized location.

I'm not familiar enough with other architectures to know what to add there. Powerpc appears to already add various .dtb files into $(targets), but the other archs may need something added to $(targets) to work.
