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.

[ Upstream commit 2dbc644ac6 ]
For rpm-pkg and deb-pkg, a source tar file is created. All paths in
the archive must be prefixed with the base name of the tar so that
everything is contained in the directory when you extract it.
Currently, scripts/package/Makefile uses a symlink for that, and
removes it after the tar is created.
If you terminate the build during the tar creation, the symlink is
left over. Then, at the next package build, you will see a warning
like follows:
ln: '.' and 'kernel-4.14.0+/.' are the same file
It is possible to fix it by adding -n (--no-dereference) option to
the "ln" command, but a cleaner way is to use --transform option
of "tar" command. This option is GNU extension, but it should not
hurt to use it in the Linux build system.
The 'S' flag is needed to exclude symlinks from the path fixup.
Without it, symlinks in the kernel are broken.

cc-option uses KBUILD_CFLAGS and KBUILD_CPPFLAGS when it determines
whether an option is supported or not. This is fine for options used to
build the kernel itself, however some components like the x86 boot code
use a different set of flags.
Add the new macro __cc-option which is a more generic version of
cc-option with additional parameters. One parameter is the compiler
with which the check should be performed, the other the compiler options
to be used instead KBUILD_C*FLAGS.
Refactor cc-option and hostcc-option to use __cc-option and move
hostcc-option to scripts/Kbuild.include.

Since commit c3f0d0bc5b ("kbuild, LLVMLinux: Add -Werror to
cc-option to support clang"), cc-option and friends work nicely
for clang.
However, -Wno-unknown-warning-option makes clang happy with any
unknown warning options even if -Werror is specified.
Once -Wno-unknown-warning-option is added, any succeeding call of
cc-disable-warning is evaluated positive, then unknown warning
options are accepted. This should be dropped.

This part ended up in redundant code after touched by multiple
people.
[1] Commit 3234282f33 ("x86, asm: Fix CFI macro invocations to
deal with shortcomings in gas") added parentheses for defined
expressions to support old gas for x86.
[2] Commit a22dcdb003 ("x86, asm: Fix ancient-GAS workaround")
split the pattern into two to avoid parentheses for non-numeric
expressions.
[3] Commit 95a2f6f72d ("Partially revert patch that encloses
asm-offset.h numbers in brackets") removed parentheses from numeric
expressions as well because parentheses in MN10300 assembly have a
special meaning (pointer access).
Apparently, there is a conflict between [1] and [3]. After all,
[3] took precedence, and a long time has passed since then.
Now, merge the two patterns again because the first one is covered
by the other.

(cherry picked from commit cc65e82336)
krealloc() must not be used against devm_*() allocated
memory regions:
- if a bigger memory is to be allocated, krealloc() and
__krealloc() could return a different pointer than the
one given to them, creating a memory region which is not
managed, thus it will not be automatically released on
device removal.
- if a bigger memory is to be allocated, krealloc() could
kfree() the managed memory region which is passed to it.
The old pointer is left registered as a resource for the
device. On device removal, this dangling pointer will be
used and an unrelated memory region could be released.
- if the requested size is equal to 0, krealloc() can also
just behave like kfree(). Here too, the old pointer is
kept associated with the device. On device removal, this
invalid pointer will be used and an unrelated memory
region could be released.
For all these reasons, krealloc() must not be used on a
pointer returned by devm_*() functions.

(cherry picked from commit 8f551befa2)
Unsigned expressions cannot be lesser than zero. Presence of comparisons
'unsigned (<|<=|>|>=) 0' often indicates a bug, usually wrong type of variable.
The patch beside finding such comparisons tries to eliminate false positives,
mainly by bypassing range checks.
gcc can detect such comparisons also using -Wtype-limits switch, but it warns
also in correct cases, making too much noise.
