perf stat: Turn off summary for interval mode by default
There's a risk that outputting interval mode summaries by default breaks
CSV consumers. It already broke pmu-tools/toplev.
So now we turn off the summary by default but we create a new option
'--summary' to enable the summary. This is active even when not using
CSV mode.

dm thin metadata: Fix use-after-free in dm_bm_set_read_only
The following error ocurred when testing disk online/offline:
[ 301.798344] device-mapper: thin: 253:5: aborting current metadata transaction
[ 301.848441] device-mapper: thin: 253:5: failed to abort metadata transaction
[ 301.849206] Aborting journal on device dm-26-8.
[ 301.850489] EXT4-fs error (device dm-26) in __ext4_new_inode:943: Journal has aborted
[ 301.851095] EXT4-fs (dm-26): Delayed block allocation failed for inode 398742 at logical offset 181 with max blocks 19 with error 30
[ 301.854476] BUG: KASAN: use-after-free in dm_bm_set_read_only+0x3a/0x40 [dm_persistent_data]
Reason is:
metadata_operation_failed
abort_transaction
dm_pool_abort_metadata
__create_persistent_data_objects
r = __open_or_format_metadata
if (r) --> If failed will free pmd->bm but pmd->bm not set NULL
dm_block_manager_destroy(pmd->bm);
set_pool_mode
dm_pool_metadata_read_only(pool->pmd);
dm_bm_set_read_only(pmd->bm); --> use-after-free
Add checks to see if pmd->bm is NULL in dm_bm_set_read_only and
dm_bm_set_read_write functions. If bm is NULL it means creating the
bm failed and so dm_bm_is_read_only must return true.

we can't grab a reference on those and don't need to add them to the set for
reverse path check anyway.

perf tools fixes for v5.9:
- Fix infinite loop in the TUI for grouped events in 'perf top/record', for
instance when using "perf top -e '{cycles,instructions,cache-misses}'.
- Fix segfault by skipping side-band event setup if HAVE_LIBBPF_SUPPORT is not set.
- Fix synthesized branch stacks generated from CoreSight ETM trace and Intel PT
hardware traces.
- Fix error when synthesizing events from ARM SPE hardware trace.
- The SNOOPX and REMOTE offsets in the data_src bitmask in perf records were
were both 37, SNOOPX is 38, fix it.
- Fix use of CPU list with summary option in 'perf sched timehist'.
- Avoid an uninitialized read when using fake PMUs.
- Set perf_event_attr.exclude_guest=1 for user-space counting.
- Don't order events when doing a 'perf report -D' raw dump of perf.data records.
- Set NULL sentinel in pmu_events table in "Parse and process metrics" 'perf test'
- Fix basic bpf filtering 'perf test' on s390x.
- Fix out of bounds array access in the 'perf stat' print_counters() evlist method.
- Add mwait_idle_with_hints.constprop.0 to the list of idle symbols.
- Use %zd for size_t printf formats on 32-bit.
- Correct the help info of "perf record --no-bpf-event" option.
- Add entries for CoreSight and Arm SPE tooling to MAINTAINERS.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

dm integrity: fix error reporting in bitmap mode after creation
The dm-integrity target did not report errors in bitmap mode just after
creation. The reason is that the function integrity_recalc didn't clean up
ic->recalc_bitmap as it proceeded with recalculation.
Fix this by updating the bitmap accordingly -- the double shift serves
to rounddown.

dm writecache: handle DAX to partitions on persistent memory correctly
The function dax_direct_access doesn't take partitions into account,
it always maps pages from the beginning of the device. Therefore,
persistent_memory_claim() must get the partition offset using
get_start_sect() and add it to the page offsets passed to
dax_direct_access().

perf tools: Correct SNOOPX field offset
perf_event.h has macros that define the field offsets in the data_src
bitmask in perf records. The SNOOPX and REMOTE offsets were both 37.
These are distinct fields, and the bitfield layout in perf_mem_data_src
confirms that SNOOPX should be at offset 38.

perf top/report: Fix infinite loop in the TUI for grouped events
For a while we need to have a dummy event for doing things like
receiving PERF_RECORD_COMM, PERF_RECORD_EXEC, etc for threads being
created and dying while we synthesize the pre-existing ones at tool
start.
This 'dummy' event is needed for keeping track of thread lifetime events
early in the session but are uninteresting otherwise, i.e. no need to
have it in a initial events menu for the non-grouped case, i.e. for:
# perf top -e cycles,instructions
or even for plain:
# perf top
When 'cycles' and that 'dummy' event are in place.
The code to remove that 'dummy' event ended up creating an endless loop
for the grouped case, i.e.:
# perf top -e '{cycles,instructions}'
Fix it.

perf stat: Fix out of bounds array access in the print_counters() evlist method
Fix a compile error on F32 and gcc version 10.1 on s390 in file
utils/stat-display.c. The error does not show up with make DEBUG=y. In
fact the issue shows up when using both compiler options -O6 and
-D_FORTIFY_SOURCE=2 (which are omitted with DEBUG=Y).
This is the offending call chain:
print_counter_aggr()
printout(config, -1, 0, ...) with 2nd parm id set to -1
aggr_printout(config, x, id --> -1, ...) which leads to this code:
case AGGR_NONE:
if (evsel->percore && !config->percore_show_thread) {
....
} else {
fprintf(config->output, "CPU%*d%s",
config->csv_output ? 0 : -7,
evsel__cpus(evsel)->map[id],
^^ id is -1 !!!!
config->csv_sep);
}
This is a compiler inlining issue which is detected on s390 but not on
other plattforms.
Output before:
# make util/stat-display.o
.....

perf parse-events: Set exclude_guest=1 for user-space counting
Currently if we run 'perf record -e cycles:u', exclude_guest=0.
But it doesn't make sense in most cases that we request for
user-space counting but we also get the guest report.
Of course, we also need to consider 'perf kvm' usage case that
authorized perf users on the host may only want to count guest user
space events. For example,
# perf kvm --guest record -e cycles:u
When we have 'exclude_guest=1' for 'perf kvm' usage, we may get nothing
from guest events.
To keep perf semantics consistent and clear, this patch sets
exclude_guest=1 for user-space counting but except for 'perf kvm' usage.
Before:
perf record -e cycles:u ./div
perf evlist -v
cycles:u: ..., exclude_kernel: 1, exclude_hv: 1, ...
After:
perf record -e cycles:u ./div
perf evlist -v
cycles:u: ..., exclude_kernel: 1, exclude_hv: 1, exclude_guest: 1, ...
Before:
perf kvm --guest record -e cycles:u -vvv
perf_event_attr:
size 120
{ sample_period, sample_freq } 4000
sample_type IP|TID|TIME|ID|CPU|PERIOD
read_format ID
disabled 1
inherit 1
exclude_kernel 1
exclude_hv 1
freq 1
sample_id_all 1
After:
perf kvm --guest record -e cycles:u -vvv
perf_event_attr:
size 120
{ sample_period, sample_freq } 4000
sample_type IP|TID|TIME|ID|CPU|PERIOD
read_format ID
disabled 1
inherit 1
exclude_kernel 1
exclude_hv 1
freq 1
sample_id_all 1
For Before/After, exclude_guest are both 0 for perf kvm usage.

HID: core: Sanitize event code and type when mapping input
When calling into hid_map_usage(), the passed event code is blindly stored as is, even if it doesn't fit in the associated bitmap. This event code can come from a variety of sources, including devices masquerading as input devices, only a bit more "programmable". Instead of taking the event code at face value, check that it actually fits the corresponding bitmap, and if it doesn't: - spit out a warning so that we know which device is acting up - NULLify the bitmap pointer so that we catch unexpected uses Code paths that can make use of untrusted inputs can now check that the mapping was indeed correct and bail out if not.

The Saitek X52 family of joysticks has a pair of axes that were originally (by the Windows driver) used as mouse pointer controls. The corresponding usage page is the Game Controls page, which is not recognized by the generic HID driver, and therefore, both axes get mapped to ABS_MISC. The quirk makes the second axis get mapped to ABS_MISC+1, and therefore made available separately. One Saitek X52 device is already fixed. This patch fixes the other two known devices with VID/PID 06a3:0255 and 06a3:0762. Signed-off-by: Nirenjan Krishnan <nirenjan@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz> |

Three interrupt related fixes for X86:
- Move disabling of the local APIC after invoking fixup_irqs() to ensure
that interrupts which are incoming are noted in the IRR and not ignored.
- Unbreak affinity setting. The rework of the entry code reused the
regular exception entry code for device interrupts. The vector number is
pushed into the errorcode slot on the stack which is then lifted into an
argument and set to -1 because that's regs->orig_ax which is used in
quite some places to check whether the entry came from a syscall. But it
was overlooked that orig_ax is used in the affinity cleanup code to
validate whether the interrupt has arrived on the new target. It turned
out that this vector check is pointless because interrupts are never
moved from one vector to another on the same CPU. That check is a
historical leftover from the time where x86 supported multi-CPU
affinities, but not longer needed with the now strict single CPU
affinity. Famous last words ...
- Add a missing check for an empty cpumask into the matrix allocator. The
affinity change added a warning to catch the case where an interrupt is
moved on the same CPU to a different vector. This triggers because a
condition with an empty cpumask returns an assignment from the allocator
as the allocator uses for_each_cpu() without checking the cpumask for
being empty. The historical inconsistent for_each_cpu() behaviour of
ignoring the cpumask and unconditionally claiming that CPU0 is in the
mask striked again. Sigh.

A set of fixes for interrupt chip drivers:
- Revert the platform driver conversion of interrupt chip drivers as it
turned out to create more problems than it solves.
- Fix a trivial typo in the new module helpers which made probing reliably
fail.
- Small fixes in the STM32 and MIPS Ingenic drivers
- The TI firmware rework which had badly managed dependencies and had to
wait post rc1.

A set of fixes for lockdep, tracing and RCU:
- Prevent recursion by using raw_cpu_* operations
- Fixup the interrupt state in the cpu idle code to be consistent
- Push rcu_idle_enter/exit() invocations deeper into the idle path so
that the lock operations are inside the RCU watching sections
- Move trace_cpu_idle() into generic code so it's called before RCU goes
idle.
- Handle raw_local_irq* vs. local_irq* operations correctly
- Move the tracepoints out from under the lockdep recursion handling
which turned out to be fragile and inconsistent.
