Perf events changes in this cycle were:
- Improve Intel uncore PMU support:
- Parse uncore 'discovery tables' - a new hardware capability enumeration method
introduced on the latest Intel platforms. This table is in a well-defined PCI
namespace location and is read via MMIO. It is organized in an rbtree.
These uncore tables will allow the discovery of standard counter blocks, but
fancier counters still need to be enumerated explicitly.
- Add Alder Lake support
- Improve IIO stacks to PMON mapping support on Skylake servers
- Add Intel Alder Lake PMU support - which requires the introduction of 'hybrid' CPUs
and PMUs. Alder Lake is a mix of Golden Cove ('big') and Gracemont ('small' - Atom derived)
cores.
The CPU-side feature set is entirely symmetrical - but on the PMU side there's
core type dependent PMU functionality.
- Reduce data loss with CPU level hardware tracing on Intel PT / AUX profiling, by
fixing the AUX allocation watermark logic.
- Improve ring buffer allocation on NUMA systems
- Put 'struct perf_event' into their separate kmem_cache pool
- Add support for synchronous signals for select perf events. The immediate motivation
is to support low-overhead sampling-based race detection for user-space code. The
feature consists of the following main changes:
- Add thread-only event inheritance via perf_event_attr::inherit_thread, which limits
inheritance of events to CLONE_THREAD.
- Add the ability for events to not leak through exec(), via perf_event_attr::remove_on_exec.
- Allow the generation of SIGTRAP via perf_event_attr::sigtrap, extend siginfo with an u64
::si_perf, and add the breakpoint information to ::si_addr and ::si_perf if the event is
PERF_TYPE_BREAKPOINT.
The siginfo support is adequate for breakpoints right now - but the new field can be used
to introduce support for other types of metadata passed over siginfo as well.
- Misc fixes, cleanups and smaller updates.

Objtool updates in this cycle were:
- Standardize the crypto asm code so that it looks like compiler-generated
code to objtool - so that it can understand it. This enables unwinding
from crypto asm code - and also fixes the last known remaining objtool
warnings for LTO and more.
- x86 decoder fixes: clean up and fix the decoder, and also extend it a bit
- Misc fixes and cleanups

linux-kselftest-kunit-5.13-rc1
This KUnit update for Linux 5.13-rc1 consists of several fixes and
new feature to support failure from dynamic analysis tools such as
UBSAN and fake ops for testing.
- a fake ops struct for testing a "free" function to complain if it
was called with an invalid argument, or caught a double-free. Most
return void and have no normal means of signalling failure
(e.g. super_operations, iommu_ops, etc.).

spi: Updates for v5.13
The only core work for SPI this time around is the completion of the
conversion to the new style method for specifying transfer delays,
meaning we can cope with what most controllers support more directly
using conversions in the core rather than open coding in drivers.
Otherwise it's a good stack of cleanups and fixes plus a few new
drivers.
The conversion to new style transfer delay will cause an issue with a
newly added staging driver which has a straightforward resolution in
-next.
- Completion of the conversion to new style transfer delay
configuration.
- Introduction and use of module_parport_driver() helper, merged here
as there's no parport tree.
- Support for Altera SoCs on DFL buses, NXP i.MX8DL, HiSilicon Kunpeng,
MediaTek MT8195,

It's been a relatively busy cycle in docsland, though more than usually
well contained to Documentation/ itself. Highlights include:
- The Chinese translators have been busy and show no signs of stopping
anytime soon. Italian has also caught up.
- Aditya Srivastava has been working on improvements to the kernel-doc
script.
- Thorsten continues his work on reporting-issues.rst and related
documentation around regression reporting.
- Lots of documentation updates, typo fixes, etc. as usual

Staging/IIO driver updates for 5.13-rc1
Here is the big set of staging and IIO driver updates for 5.13-rc1.
Lots of little churn in here, and some larger churn as well. Major
things are:
- removal of wimax drivers, no one has this hardware anymore for
this failed "experiment".
- removal of the Google gasket driver, turns out no one wanted
to maintain it or cares about it anymore, so they asked for it
to be removed.
- comedi finally moves out of the staging directory into
drivers/comedi/ This is one of the oldest kernel subsystems
around, being created in the 2.0 kernel days, and was one of
the first things added to drivers/staging/ when that was
created over 15 years ago. It should have been moved out of
staging a long time ago, it's well maintained and used by
loads of different devices in the real world every day. Nice
to see this finally happen.
- so many tiny coding style cleanups it's not funny. Perfect
storm of at least 2 different intern project application
deadlines combined to provide a huge number of new
contributions in this area from people learning how to do
kernel development. Great job to everyone involved here.
There's also the normal updates for IIO drivers with new IIO drivers and
updates all over that subsystem.
All of these have been in linux-next for a while with no reported
issues.

Driver core changes for 5.13-rc1
Here is the "big" set of driver core changes for 5.13-rc1.
Nothing major, just lots of little core changes and cleanups, notable
things are:
- finally set fw_devlink=on by default. All reported issues
with this have been shaken out over the past 9 months or so,
but we will be paying attention to any fallout here in case we
need to revert this as the default boot value (symptoms of
problems are a simple lack of booting)
- fixes found to be needed by fw_devlink=on value in some
subsystems (like clock).
- delayed work initialization cleanup
- driver core cleanups and minor updates
- software node cleanups and tweaks
- devtmpfs cleanups
- minor debugfs cleanups
All of these have been in linux-next for a while with no reported
issues.

arm64 updates for 5.13:
- MTE asynchronous support for KASan. Previously only synchronous
(slower) mode was supported. Asynchronous is faster but does not allow
precise identification of the illegal access.
- Run kernel mode SIMD with softirqs disabled. This allows using NEON in
softirq context for crypto performance improvements. The conditional
yield support is modified to take softirqs into account and reduce the
latency.
- Preparatory patches for Apple M1: handle CPUs that only have the VHE
mode available (host kernel running at EL2), add FIQ support.
- arm64 perf updates: support for HiSilicon PA and SLLC PMU drivers, new
functions for the HiSilicon HHA and L3C PMU, cleanups.
- Re-introduce support for execute-only user permissions but only when
the EPAN (Enhanced Privileged Access Never) architecture feature is
available.
- Disable fine-grained traps at boot and improve the documented boot
requirements.
- Support CONFIG_KASAN_VMALLOC on arm64 (only with KASAN_GENERIC).
- Add hierarchical eXecute Never permissions for all page tables.
- Add arm64 prctl(PR_PAC_{SET,GET}_ENABLED_KEYS) allowing user programs
to control which PAC keys are enabled in a particular task.
- arm64 kselftests for BTI and some improvements to the MTE tests.
- Minor improvements to the compat vdso and sigpage.
- Miscellaneous cleanups.

Entry code update:
Provide support for randomized stack offsets per syscall to make stack-based attacks harder which rely on the deterministic stack layout. The feature is based on the original idea of PaX's RANDSTACK feature, but uses a significantly different implementation. The offset does not affect the pt_regs location on the task stack as this was agreed on to be of dubious value. The offset is applied before the actual syscall is invoked. The offset is stored per cpu and the randomization happens at the end of the syscall which is less predictable than on syscall entry. The mechanism to apply the offset is via alloca(), i.e. abusing the dispised VLAs. This comes with the drawback that stack-clash-protection has to be disabled for the affected compilation units and there is also a negative interaction with stack-protector. Those downsides are traded with the advantage that this approach does not require any intrusive changes to the low level assembly entry code, does not affect the unwinder and the correct stack alignment is handled automatically by the compiler. The feature is guarded with a static branch which avoids the overhead when disabled. Currently this is supported for X86 and ARM64. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmCGjz8THHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoWsvD/4tGnPAurd6lbzxWzRjW7jOOVyzkODM UXtIxxICaj7o6MNcloaGe1QtJ8+QOCw3yPQfLG/SoWHse5+oUKQRL9dmWVeJyRSt JZ1pirkKqWrB+OmPbJKUiO3/TsZ2Z/vO41JVgVTL5/HWhOECSDzZsJkuvF/H+qYD ReDzd7FUNd76pwVOsXq/cxXclRa81/wMNZRVwmyAwFYE2XoPtQyTERTLrfj6aQKF P0txr9fEjYlPPwYOk1kjBAoJfDltNm48BBL7CGZtRlsqpNpdsJ1MkeGffhodb6F0 pJYQMlQJHXABZb5GF+v93+iASDpRFn0EvPmLkCxQUfZYLOkRsnuEF2S/fsYX/WPo uin/wQKwLVdeQq9d9BwlZUKEgsQuV7Q0GVN+JnEQerwD6cWTxv4a1RIUH+K/4Wo5 nTeJVRKcs6m7UkGQRm8JbqnUP0vCV+PSiWWB8J9CmjYeCPbkGjt6mBIsmPaDZ9VL 4i+UX5DJayoREF/rspOBcJftUmExize49p9860UI9N6fd7DsDt7Dq9Ai+ADtZa4C 9BPbF4NWzJq8IWLqBi+PpKBAT3JMX9qQi7s9sbrRxpxtew9Keu5qggKZJYumX71V qgUMk+xB86HZOrtF6F3oY0zxYv3haPvDydsDgqojtqNGk4PdAdgDYJQwMlb8QSly SwIWPHIfvP4R9w== =GMlJ -----END PGP SIGNATURE----- Merge tag 'x86-entry-2021-04-26' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull entry code update from Thomas Gleixner: "Provide support for randomized stack offsets per syscall to make stack-based attacks harder which rely on the deterministic stack layout.

The time and timers updates contain:
Core changes:
- Allow runtime power management when the clocksource is changed.
- A correctness fix for clock_adjtime32() so that the return value
on success is not overwritten by the result of the copy to user.
- Allow late installment of broadcast clockevent devices which was
broken because nothing switched them over to oneshot mode. This went
unnoticed so far because clockevent devices used to be built in, but
now people started to make them modular.
- Debugfs related simplifications
- Small cleanups and improvements here and there
Driver changes:
- The usual set of device tree binding updates for a wide range
of drivers/devices.
- The usual updates and improvements for drivers all over the place but
nothing outstanding.
- No new clocksource/event drivers. They'll come back next time.

perf ftrace: Fix access to pid in array when setting a pid filter
Command 'perf ftrace -v -- ls' fails in s390 (at least 5.12.0rc6).
The root cause is a missing pointer dereference which causes an

Fix this by extracting the PID.

perf auxtrace: Fix potential NULL pointer dereference
In the function auxtrace_parse_snapshot_options(), the callback pointer
"itr->parse_snapshot_options" can be NULL if it has not been set during
the AUX record initialization. This can cause tool crashing if the
callback pointer "itr->parse_snapshot_options" is dereferenced without
performing NULL check.
Add a NULL check for the pointer "itr->parse_snapshot_options" before
invoke the callback.

signal, perf: Fix siginfo_t by avoiding u64 on 32-bit architectures
The alignment of a structure is that of its largest member. On
architectures like 32-bit Arm (but not e.g. 32-bit x86) 64-bit integers
will require 64-bit alignment and not its natural word size.
This means that there is no portable way to add 64-bit integers to
siginfo_t on 32-bit architectures without breaking the ABI, because
siginfo_t does not yet (and therefore likely never will) contain 64-bit
fields on 32-bit architectures. Adding a 64-bit integer could change the
alignment of the union after the 3 initial int si_signo, si_errno,
si_code, thus introducing 4 bytes of padding shifting the entire union,
which would break the ABI.
One alternative would be to use the __packed attribute, however, it is
non-standard C. Given siginfo_t has definitions outside the Linux kernel
in various standard libraries that can be compiled with any number of
different compilers (not just those we rely on), using non-standard
attributes on siginfo_t should be avoided to ensure portability.
In the case of the si_perf field, word size is sufficient since there is
no exact requirement on size, given the data it contains is user-defined
via perf_event_attr::sig_data. On 32-bit architectures, any excess bits
of perf_event_attr::sig_data will therefore be truncated when copying
into si_perf.
Since si_perf is intended to disambiguate events (e.g. encoding relevant
information if there are more events of the same type), 32 bits should
provide enough entropy to do so on 32-bit architectures.
For 64-bit architectures, no change is intended.

there anyway as the ia64-specific errno.h was just a wrapper for the
generic header.

bpf: Update selftests to reflect new error states
Update various selftest error messages: * The 'Rx tried to sub from different maps, paths, or prohibited types' is reworked into more specific/differentiated error messages for better guidance. * The change into 'value -4294967168 makes map_value pointer be out of bounds' is due to moving the mixed bounds check into the speculation handling and thus occuring slightly later than above mentioned sanity check. * The change into 'math between map_value pointer and register with unbounded min value' is similarly due to register sanity check coming before the mixed bounds check. * The case of 'map access: known scalar += value_ptr from different maps' now loads fine given masks are the same from the different paths (despite max map value size being different).

selftests/perf_events: Add kselftest for remove_on_exec
Add kselftest to test that remove_on_exec removes inherited events from child tasks. Signed-off-by: Marco Elver <elver@google.com> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Link: https://lkml.kernel.org/r/20210408103605.1676875-9-elver@google.com |

selftests/perf_events: Add kselftest for process-wide sigtrap handling
Add a kselftest for testing process-wide perf events with synchronous SIGTRAP on events (using breakpoints). In particular, we want to test that changes to the event propagate to all children, and the SIGTRAPs are in fact synchronously sent to the thread where the event occurred. Note: The "signal_stress" test case is also added later in the series to perf tool's built-in tests. The test here is more elaborate in that respect, which on one hand avoids bloating the perf tool unnecessarily, but we also benefit from structured tests with TAP-compliant output that the kselftest framework provides.

perf intel-pt: Use aux_watermark
Turns out, the default setting of attr.aux_watermark to half of the total buffer size is not very useful, especially with smaller buffers. The problem is that, after half of the buffer is filled up, the kernel updates ->aux_head and sets up the next "transaction", while observing that ->aux_tail is still zero (as userspace haven't had the chance to update it), meaning that the trace will have to stop at the end of this second "transaction". This means, for example, that the second PERF_RECORD_AUX in every trace comes with TRUNCATED flag set. Setting attr.aux_watermark to quarter of the buffer gives enough space for the ->aux_tail update to be observed and prevents the data loss. The obligatory before/after showcase: > # perf_before record -e intel_pt//u -m,8 uname > Linux > [ perf record: Woken up 6 times to write data ] > Warning: > AUX data lost 4 times out of 10! > > [ perf record: Captured and wrote 0.099 MB perf.data ] > # perf record -e intel_pt//u -m,8 uname > Linux > [ perf record: Woken up 4 times to write data ] > [ perf record: Captured and wrote 0.039 MB perf.data ] The effect is still visible with large workloads and large buffers, although less pronounced.
