ARM: 8984/1: Kconfig: set default ZBOOT_ROM_TEXT/BSS value to 0x0
ZBOOT_ROM_TEXT and ZBOOT_ROM_BSS are defined as 'hex' but had a default of "0". Kconfig will helpfully expand a text entry of 0 to 0x0 but because this is not the same as the default value it was treated as being explicitly set when running 'make savedefconfig' so most arm defconfigs have CONFIG_ZBOOT_ROM_TEXT=0x0 and CONFIG_ZBOOT_ROM_BSS=0x0. Change the default to 0x0 which will mean next time the defconfigs are re-generated the spurious config entries will be removed.

The Kernel Concurrency Sanitizer (KCSAN)
KCSAN is a dynamic race detector, which relies on compile-time instrumentation, and uses a watchpoint-based sampling approach to detect races. The feature was under development for quite some time and has already found legitimate bugs. Unfortunately it comes with a limitation, which was only understood late in the development cycle: It requires an up to date CLANG-11 compiler CLANG-11 is not yet released (scheduled for June), but it's the only compiler today which handles the kernel requirements and especially the annotations of functions to exclude them from KCSAN instrumentation correctly. These annotations really need to work so that low level entry code and especially int3 text poke handling can be completely isolated. A detailed discussion of the requirements and compiler issues can be found here: https://lore.kernel.org/lkml/CANpmjNMTsY_8241bS7=XAfqvZHFLrVEkv_uM4aDUWE_kh3Rvbw@mail.gmail.com/ We came to the conclusion that trying to work around compiler limitations and bugs again would end up in a major trainwreck, so requiring a working compiler seemed to be the best choice. For Continous Integration purposes the compiler restriction is manageable and that's where most xxSAN reports come from. For a change this limitation might make GCC people actually look at their bugs. Some issues with CSAN in GCC are 7 years old and one has been 'fixed' 3 years ago with a half baken solution which 'solved' the reported issue but not the underlying problem. The KCSAN developers also ponder to use a GCC plugin to become independent, but that's not something which will show up in a few days. Blocking KCSAN until wide spread compiler support is available is not a really good alternative because the continuous growth of lockless optimizations in the kernel demands proper tooling support. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAl7im98THHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoQ3xD/9+q87OmwnyoRTs6O3GDDbWZYoJGolh rctDOAYW8RSS73Fiw23z8hKlLl9tJCya6/X8Q9qoonB1YeIEPPRVj5HJWAMUNEIs YgjlZJFmh+mnbP/KQFctm3AWpoX8kqt3ncqj6zG72oQ9qKui691BY/2NmGVSLxUV DqtUYSKmi51XEQtZuXRuHEf3zBxoyeD43DaSCdJAXd6f5O2X7tmrWDuazHVeKzHV lhijvkyBvGMWvPg0IBrXkkLmeOvS0++MTGm3o+L72XF6nWpzTkcV7N0E9GEDFg45 zwcidRVKD5d/1DoU5Tos96rCJpBEGh/wimlu0z14mcZpNiJgRQH5rzVEO9Y14UcP KL9FgRrb5dFw7yfX2zRQ070OFJ4AEDBMK0o5Lbu/QO5KLkvFkqnuWlQfmmtZJWCW DTRw/FgUgU7lvyPjRrao6HBvwy+yTb0u9K5seCOTRkuepR9nPJs0710pFiBsNCfV RY3cyggNBipAzgBOgLxixnq9+rHt70ton6S8Gijxpvt0dGGfO8k0wuEhFtA4zKrQ 6HGK+pidxnoVdEgyQZhS+qzMMkyiUL0FXdaGJ2IX+/DC+Ij1UrUPjZBn7v25M0hQ ESkvxWKCn7snH4/NJsNxqCV1zyEc3zAW/WvLJUc9I7H8zPwtVvKWPrKEMzrJJ5bA aneySilbRxBFUg== =iplm -----END PGP SIGNATURE----- Merge tag 'locking-kcsan-2020-06-11' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull the Kernel Concurrency Sanitizer from Thomas Gleixner: "The Kernel Concurrency Sanitizer (KCSAN) is a dynamic race detector, which relies on compile-time instrumentation, and uses a watchpoint-based sampling approach to detect races.

Peter Zijlstras rework of atomics and fallbacks. This solves two problems:
1) Compilers uninline small atomic_* static inline functions which can
expose them to instrumentation.
2) The instrumentation of atomic primitives was done at the architecture
level while composites or fallbacks were provided at the generic level.
As a result there are no uninstrumented variants of the fallbacks.
Both issues were in the way of fully isolating fragile entry code pathes
and especially the text poke int3 handler which is prone to an endless
recursion problem when anything in that code path is about to be
instrumented. This was always a problem, but got elevated due to the new
batch mode updates of tracing.
The solution is to mark the functions __always_inline and to flip the
fallback and instrumentation so the non-instrumented variants are at the
architecture level and the instrumentation is done in generic code.
The latter introduces another fallback variant which will go away once all
architectures have been moved over to arch_atomic_*.

lib/lzo: fix ambiguous encoding bug in lzo-rle
In some rare cases, for input data over 32 KB, lzo-rle could encode two different inputs to the same compressed representation, so that decompression is then ambiguous (i.e. data may be corrupted - although zram is not affected because it operates over 4 KB pages). This modifies the compressor without changing the decompressor or the bitstream format, such that: - there is no change to how data produced by the old compressor is decompressed - an old decompressor will correctly decode data from the updated compressor - performance and compression ratio are not affected - we avoid introducing a new bitstream format In testing over 12.8M real-world files totalling 903 GB, three files were affected by this bug. I also constructed 37M semi-random 64 KB files totalling 2.27 TB, and saw no affected files. Finally I tested over files constructed to contain each of the ~1024 possible bad input sequences; for all of these cases, updated lzo-rle worked correctly. There is no significant impact to performance or compression ratio.

mm/memory-failure: prioritize prctl(PR_MCE_KILL) over vm.memory_failure_early_kill
Patch series "hwpoison: fixes signaling on memory error" This is a small patchset to solve issues in memory error handler to send SIGBUS to proper process/thread as expected in configuration. Please see descriptions in individual patches for more details. This patch (of 2): Early-kill policy is controlled from two types of settings, one is per-process setting prctl(PR_MCE_KILL) and the other is system-wide setting vm.memory_failure_early_kill. Users expect per-process setting to override system-wide setting as many other settings do, but early-kill setting doesn't work as such. For example, if a system configures vm.memory_failure_early_kill to 1 (enabled), a process receives SIGBUS even if it's configured to explicitly disable PF_MCE_KILL by prctl(). That's not desirable for applications with their own policies. This patch is suggesting to change the priority of these two types of settings, by checking sysctl_memory_failure_early_kill only when a given process has the default kill policy. Note that this patch is solving a thread choice issue too. Originally, collect_procs() always chooses the main thread when vm.memory_failure_early_kill is 1, even if the process has a dedicated thread for memory error handling. SIGBUS should be sent to the dedicated thread if early-kill is enabled via vm.memory_failure_early_kill as we are doing for PR_MCE_KILL_EARLY processes.

A set of fixes and updates for x86:
- Unbreak paravirt VDSO clocks. While the VDSO code was moved into lib
for sharing a subtle check for the validity of paravirt clocks got
replaced. While the replacement works perfectly fine for bare metal as
the update of the VDSO clock mode is synchronous, it fails for paravirt
clocks because the hypervisor can invalidate them asynchronous. Bring
it back as an optional function so it does not inflict this on
architectures which are free of PV damage.
- Fix the jiffies to jiffies64 mapping on 64bit so it does not trigger
an ODR violation on newer compilers
- Three fixes for the SSBD and *IB* speculation mitigation maze to ensure
consistency, not disabling of some *IB* variants wrongly and to prevent
a rogue cross process shutdown of SSBD. All marked for stable.
- Add yet more CPU models to the splitlock detection capable list !@#%$!
- Bring the pr_info() back which tells that TSC deadline timer is enabled.

Merge tag 'x86-urgent-2020-06-11' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull more x86 updates from Thomas Gleixner:
"A set of fixes and updates for x86:
- Unbreak paravirt VDSO clocks.
While the VDSO code was moved into lib for sharing a subtle check
for the validity of paravirt clocks got replaced. While the
replacement works perfectly fine for bare metal as the update of
the VDSO clock mode is synchronous, it fails for paravirt clocks
because the hypervisor can invalidate them asynchronously.
Bring it back as an optional function so it does not inflict this
on architectures which are free of PV damage.
- Fix the jiffies to jiffies64 mapping on 64bit so it does not
trigger an ODR violation on newer compilers
- Three fixes for the SSBD and *IB* speculation mitigation maze to
ensure consistency, not disabling of some *IB* variants wrongly and
to prevent a rogue cross process shutdown of SSBD. All marked for
stable.
- Add yet more CPU models to the splitlock detection capable list
!@#%$!
- Bring the pr_info() back which tells that TSC deadline timer is
enabled.
- Reboot quirk for MacBook6,1"

dt-bindings: Fix more incorrect 'reg' property sizes in examples
The examples template is a 'simple-bus' with a size of 1 cell for had between 2 and 4 cells which really only errors on I2C or SPI type devices with a single cell. The easiest fix in most cases is to change the 'reg' property to 1 cell for address and size.

fix that, too.

dt-bindings: Remove more cases of 'allOf' containing a '$ref'
Another round of 'allOf' removals that came in this cycle. json-schema versions draft7 and earlier have a weird behavior in that any keywords combined with a '$ref' are ignored (silently). The correct form was to put a '$ref' under an 'allOf'. This behavior is now changed in the 2019-09 json-schema spec and '$ref' can be mixed with other keywords. The json-schema library doesn't yet support this, but the tooling now does a fixup for this and either way works. This has been a constant source of review comments, so let's change this treewide so everyone copies the simpler syntax. Signed-off-by: Rob Herring <robh@kernel.org> |

compiler_types.h, kasan: Use __SANITIZE_ADDRESS__ instead of CONFIG_KASAN to decide inlining
Use __always_inline in compilation units that have instrumentation disabled (KASAN_SANITIZE_foo.o := n) for KASAN, like it is done for KCSAN.

compiler.h: Remove data_race() and unnecessary checks from {READ,WRITE}_ONCE()
The volatile accesses no longer need to be wrapped in data_race() because compilers that emit instrumentation distinguishing volatile accesses are required for KCSAN. Consequently, the explicit kcsan_check_atomic*() are no longer required either since the compiler emits instrumentation distinguishing the volatile accesses. Finally, simplify __READ_ONCE_SCALAR() and remove __WRITE_ONCE_SCALAR().

kcsan: Remove 'noinline' from __no_kcsan_or_inline
Some compilers incorrectly inline small __no_kcsan functions, which then results in instrumenting the accesses. For this reason, the 'noinline' attribute was added to __no_kcsan_or_inline. All known versions of GCC are affected by this. Supported versions of Clang are unaffected, and never inline a no_sanitize function. However, the attribute 'noinline' in __no_kcsan_or_inline causes unexpected code generation in functions that are __no_kcsan and call a __no_kcsan_or_inline function. In certain situations it is expected that the __no_kcsan_or_inline function is actually inlined by the __no_kcsan function, and *no* calls are emitted. By removing the 'noinline' attribute, give the compiler the ability to inline and generate the expected code in __no_kcsan functions.

kcsan: Pass option tsan-instrument-read-before-write to Clang
Clang (unlike GCC) removes reads before writes with matching addresses
in the same basic block. This is an optimization for TSAN, since writes
will always cause conflict if the preceding read would have.
However, for KCSAN we cannot rely on this option, because we apply
several special rules to writes, in particular when the
KCSAN_ASSUME_PLAIN_WRITES_ATOMIC option is selected. To avoid missing
potential data races, pass the -tsan-instrument-read-before-write option
to Clang if it is available [1].

kcsan: Support distinguishing volatile accesses
In the kernel, the "volatile" keyword is used in various concurrent
contexts, whether in low-level synchronization primitives or for
legacy reasons. If supported by the compiler, it will be assumed
that aligned volatile accesses up to sizeof(long long) (matching
compiletime_assert_rwonce_type()) are atomic.
Recent versions of Clang [1] (GCC tentative [2]) can instrument
volatile accesses differently. Add the option (required) to enable the
instrumentation, and provide the necessary runtime functions. None of
the updated compilers are widely available yet (Clang 11 will be the
first release to support the feature).

kcsan: Restrict supported compilers
The first version of Clang that supports -tsan-distinguish-volatile will
be able to support KCSAN. The first Clang release to do so, will be
Clang 11. This is due to satisfying all the following requirements:
1. Never emit calls to __tsan_func_{entry,exit}.
2. __no_kcsan functions should not call anything, not even
kcsan_{enable,disable}_current(), when using __{READ,WRITE}_ONCE => Requires
leaving them plain!
3. Support atomic_{read,set}*() with KCSAN, which rely on
arch_atomic_{read,set}*() using __{READ,WRITE}_ONCE() => Because of
#2, rely on Clang 11's -tsan-distinguish-volatile support. We will
double-instrument atomic_{read,set}*(), but that's reasonable given
it's still lower cost than the data_race() variant due to avoiding 2
extra calls (kcsan_{en,dis}able_current() calls).
4. __always_inline functions inlined into __no_kcsan functions are never
instrumented.
5. __always_inline functions inlined into instrumented functions are
instrumented.
6. __no_kcsan_or_inline functions may be inlined into __no_kcsan functions =>
Implies leaving 'noinline' off of __no_kcsan_or_inline.
7. Because of #6, __no_kcsan and __no_kcsan_or_inline functions should never be
spuriously inlined into instrumented functions, causing the accesses of the
__no_kcsan function to be instrumented.
Older versions of Clang do not satisfy #3. The latest GCC currently
doesn't support at least #1, #3, and #7.
