tracing / histogram: Give calculation hist_fields a size
When working on my user space applications, I found a bug in the synthetic
event code where the automated synthetic event field was not matching the
event field calculation it was attached to. Looking deeper into it, it was
because the calculation hist_field was not given a size.
The synthetic event fields are matched to their hist_fields either by
having the field have an identical string type, or if that does not match,
then the size and signed values are used to match the fields.
The problem arose when I tried to match a calculation where the fields
were "unsigned int". My tool created a synthetic event of type "u32". But
it failed to match. The string was:
diff=field1-field2:onmatch(event).trace(synth,$diff)
Adding debugging into the kernel, I found that the size of "diff" was 0.
And since it was given "unsigned int" as a type, the histogram fallback
code used size and signed. The signed matched, but the size of u32 (4) did
not match zero, and the event failed to be created.
This can be worse if the field you want to match is not one of the
acceptable fields for a synthetic event. As event fields can have any type
that is supported in Linux, this can cause an issue. For example, if a
type is an enum. Then there's no way to use that with any calculations.
Have the calculation field simply take on the size of what it is
calculating.

tracepoints: Update static_call before tp_funcs when adding a tracepoint
Because of the significant overhead that retpolines pose on indirect
calls, the tracepoint code was updated to use the new "static_calls" that
can modify the running code to directly call a function instead of using
an indirect caller, and this function can be changed at runtime.
In the tracepoint code that calls all the registered callbacks that are
attached to a tracepoint, the following is done:
it_func_ptr = rcu_dereference_raw((&__tracepoint_##name)->funcs);
if (it_func_ptr) {
__data = (it_func_ptr)->data;
static_call(tp_func_##name)(__data, args);
}
If there's just a single callback, the static_call is updated to just call
that callback directly. Once another handler is added, then the static
caller is updated to call the iterator, that simply loops over all the
funcs in the array and calls each of the callbacks like the old method
using indirect calling.
The issue was discovered with a race between updating the funcs array and
updating the static_call. The funcs array was updated first and then the
static_call was updated. This is not an issue as long as the first element
in the old array is the same as the first element in the new array. But
that assumption is incorrect, because callbacks also have a priority
field, and if there's a callback added that has a higher priority than the
callback on the old array, then it will become the first callback in the
new array. This means that it is possible to call the old callback with
the new callback data element, which can cause a kernel panic.
static_call = callback1()
funcs[] = {callback1,data1};
callback2 has higher priority than callback1
CPU 1 CPU 2
----- -----
new_funcs = {callback2,data2},
{callback1,data1}
rcu_assign_pointer(tp->funcs, new_funcs);
/*
* Now tp->funcs has the new array
* but the static_call still calls callback1
*/
it_func_ptr = tp->funcs [ new_funcs ]
data = it_func_ptr->data [ data2 ]
static_call(callback1, data);
/* Now callback1 is called with
* callback2's data */
[ KERNEL PANIC ]
update_static_call(iterator);
To prevent this from happening, always switch the static_call to the
iterator before assigning the tp->funcs to the new array. The iterator will
always properly match the callback with its data.
To trigger this bug:
In one terminal:
while :; do hackbench 50; done
In another terminal
echo 1 > /sys/kernel/tracing/events/sched/sched_waking/enable
while :; do
echo 1 > /sys/kernel/tracing/set_event_pid;
sleep 0.5
echo 0 > /sys/kernel/tracing/set_event_pid;
sleep 0.5
done
And it doesn't take long to crash. This is because the set_event_pid adds
a callback to the sched_waking tracepoint with a high priority, which will
be called before the sched_waking trace event callback is called.
Note, the removal to a single callback updates the array first, before
changing the static_call to single callback, which is the proper order as
the first element in the array is the same as what the static_call is
being changed to.

tracing: Clean up alloc_synth_event()
alloc_synth_event() currently has the following code to initialize the
event fields and dynamic_fields:
for (i = 0, j = 0; i < n_fields; i++) {
event->fields[i] = fields[i];
if (fields[i]->is_dynamic) {
event->dynamic_fields[j] = fields[i];
event->dynamic_fields[j]->field_pos = i;
event->dynamic_fields[j++] = fields[i];
event->n_dynamic_fields++;
}
}
1) It would make more sense to have all fields keep track of their
field_pos.
2) event->dynmaic_fields[j] is assigned twice for no reason.
3) We can move updating event->n_dynamic_fields outside the loop, and just
assign it to j.
This combination makes the code much cleaner.

tracing/histogram: Rename "cpu" to "common_cpu"
Currently the histogram logic allows the user to write "cpu" in as an
event field, and it will record the CPU that the event happened on.
The problem with this is that there's a lot of events that have "cpu"
as a real field, and using "cpu" as the CPU it ran on, makes it
impossible to run histograms on the "cpu" field of events.
For example, if I want to have a histogram on the count of the
workqueue_queue_work event on its cpu field, running:
># echo 'hist:keys=cpu' > events/workqueue/workqueue_queue_work/trigger
Gives a misleading and wrong result.
Change the command to "common_cpu" as no event should have "common_*"
fields as that's a reserved name for fields used by all events. And
this makes sense here as common_cpu would be a field used by all events.
Now we can even do:
># echo 'hist:keys=common_cpu,cpu if cpu < 100' > events/workqueue/workqueue_queue_work/trigger
># cat events/workqueue/workqueue_queue_work/hist
# event histogram
#
# trigger info: hist:keys=common_cpu,cpu:vals=hitcount:sort=hitcount:size=2048 if cpu < 100 [active]
#
{ common_cpu: 0, cpu: 2 } hitcount: 1
{ common_cpu: 0, cpu: 4 } hitcount: 1
{ common_cpu: 7, cpu: 7 } hitcount: 1
{ common_cpu: 0, cpu: 7 } hitcount: 1
{ common_cpu: 0, cpu: 1 } hitcount: 1
{ common_cpu: 0, cpu: 6 } hitcount: 2
{ common_cpu: 0, cpu: 5 } hitcount: 2
{ common_cpu: 1, cpu: 1 } hitcount: 4
{ common_cpu: 6, cpu: 6 } hitcount: 4
{ common_cpu: 5, cpu: 5 } hitcount: 14
{ common_cpu: 4, cpu: 4 } hitcount: 26
{ common_cpu: 0, cpu: 0 } hitcount: 39
{ common_cpu: 2, cpu: 2 } hitcount: 184
Now for backward compatibility, I added a trick. If "cpu" is used, and
the field is not found, it will fall back to "common_cpu" and work as
it did before. This way, it will still work for old programs that use
"cpu" to get the actual CPU, but if the event has a "cpu" as a field, it
will get that event's "cpu" field, which is probably what it wants
anyway.
I updated the tracefs/README to include documentation about both the
common_timestamp and the common_cpu. This way, if that text is present in
the README, then an application can know that common_cpu is supported over
just plain "cpu".

The reason is that the dynamic events array keeps track of the field
position of the fields array, via the field_pos variable in the
synth_field structure. Unfortunately, that field is a boolean for some
reason, which means any field_pos greater than 1 will be a bug (in this
case it was 2).

tracing: Fix bug in rb_per_cpu_empty() that might cause deadloop.
The "rb_per_cpu_empty()" misinterpret the condition (as not-empty) when "head_page" and "commit_page" of "struct ring_buffer_per_cpu" points to the same buffer page, whose "buffer_data_page" is empty and "read" field is non-zero. An error scenario could be constructed as followed (kernel perspective): 1. All pages in the buffer has been accessed by reader(s) so that all of them will have non-zero "read" field. 2. Read and clear all buffer pages so that "rb_num_of_entries()" will return 0 rendering there's no more data to read. It is also required that the "read_page", "commit_page" and "tail_page" points to the same page, while "head_page" is the next page of them. 3. Invoke "ring_buffer_lock_reserve()" with large enough "length" so that it shot pass the end of current tail buffer page. Now the "head_page", "commit_page" and "tail_page" points to the same page. 4. Discard current event with "ring_buffer_discard_commit()", so that "head_page", "commit_page" and "tail_page" points to a page whose buffer data page is now empty. When the error scenario has been constructed, "tracing_read_pipe" will be trapped inside a deadloop: "trace_empty()" returns 0 since "rb_per_cpu_empty()" returns 0 when it hits the CPU containing such constructed ring buffer. Then "trace_find_next_entry_inc()" always return NULL since "rb_num_of_entries()" reports there's no more entry to read. Finally "trace_seq_to_user()" returns "-EBUSY" spanking "tracing_read_pipe" back to the start of the "waitagain" loop. I've also written a proof-of-concept script to construct the scenario and trigger the bug automatically, you can use it to trace and validate my reasoning above: https://github.com/aegistudio/RingBufferDetonator.git Tests has been carried out on linux kernel 5.14-rc2 ( |

Kbuild: lto: fix module versionings mismatch in GNU make 3.X
When building modules(CONFIG_...=m), I found some of module versions
are incorrect and set to 0.
This can be found in build log for first clean build which shows
WARNING: EXPORT symbol "XXXX" [drivers/XXX/XXX.ko] version generation failed,
symbol will not be versioned.
But in second build(incremental build), the WARNING disappeared and the
module version becomes valid CRC and make someone who want to change
modules without updating kernel image can't insert their modules.
The problematic code is
+ $(foreach n, $(filter-out FORCE,$^), \
+ $(if $(wildcard $(n).symversions), \
+ ; cat $(n).symversions >> $@.symversions))
For example:
rm -f fs/notify/built-in.a.symversions ; rm -f fs/notify/built-in.a; \
llvm-ar cDPrST fs/notify/built-in.a fs/notify/fsnotify.o \
fs/notify/notification.o fs/notify/group.o ...
`foreach n` shows nothing to `cat` into $(n).symversions because
`if $(wildcard $(n).symversions)` return nothing, but actually
they do exist during this line was executed.
-rw-r--r-- 1 root root 168580 Jun 13 19:10 fs/notify/fsnotify.o
-rw-r--r-- 1 root root 111 Jun 13 19:10 fs/notify/fsnotify.o.symversions
The reason is the $(n).symversions are generated at runtime, but
Makefile wildcard function expends and checks the file exist or not
during parsing the Makefile.
Thus fix this by use `test` shell command to check the file
existence in runtime.
Rebase from both:

perf sched: Fix record failure when CONFIG_SCHEDSTATS is not set
The tracepoints trace_sched_stat_{wait, sleep, iowait} are not exposed to user
if CONFIG_SCHEDSTATS is not set, "perf sched record" records the three events.
As a result, the command fails.
Before:
#perf sched record sleep 1
event syntax error: 'sched:sched_stat_wait'
\___ unknown tracepoint
Error: File /sys/kernel/tracing/events/sched/sched_stat_wait not found.
Hint: Perhaps this kernel misses some CONFIG_ setting to enable this feature?.
Run 'perf list' for a list of valid events
Usage: perf record [<options>] [<command>]
or: perf record [<options>] -- <command> [<options>]
-e, --event <event> event selector. use 'perf list' to list available events
Solution:
Check whether schedstat tracepoints are exposed. If no, these events are not recorded.
After:
# perf sched record sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.163 MB perf.data (1091 samples) ]
# perf sched report
run measurement overhead: 4736 nsecs

perf probe: Fix add event failure when running 32-bit perf in a 64-bit kernel
The "address" member of "struct probe_trace_point" uses long data type.
If kernel is 64-bit and perf program is 32-bit, size of "address"
variable is 32 bits.
As a result, upper 32 bits of address read from kernel are truncated, an
error occurs during address comparison in kprobe_warn_out_range().
Before:
# perf probe -a schedule
schedule is out of .text, skip it.
Error: Failed to add events.
Solution:
Change data type of "address" variable to u64 and change corresponding
address printing and value assignment.
After:
# perf.new.new probe -a schedule
Added new event:
probe:schedule (on schedule)
You can now use it in all perf tools, such as:
perf record -e probe:schedule -aR sleep 1
# perf probe -l
probe:schedule (on schedule@kernel/sched/core.c)
# perf record -e probe:schedule -aR sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.156 MB perf.data (1366 samples) ]
# perf report --stdio
# To display the perf.data header info, please use --header/--header-only options.

perf probe-file: Delete namelist in del_events() on the error path
ASan reports some memory leaks when running:
# perf test "42: BPF filter"
This second leak is caused by a strlist not being dellocated on error
inside probe_file__del_events.
This patch adds a goto label before the deallocation and makes the error

ARM: SoC fixes for v5.14
Here are the patches for this week that came as the fallout of
the merge window:
- Two fixes for the NVidia memory controller driver
- multiple defconfig files get patched to turn CONFIG_FB back on
after that is no longer selected by CONFIG_DRM
- ffa and scmpi firmware drivers fixes, mostly addressing compiler
and documentation warnings
- Platform specific fixes for device tree files on ASpeed,
Renesas and NVidia SoC, mostly for recent regressions.
- A workaround for a regression on the USB PHY with devlink when
the usb-nop-xceiv driver is not available until the rootfs is
mounted.
- Device tree compiler warnings in Arm Versatile-AB

tracing: Fix the histogram logic from possibly crashing the kernel
Working on the histogram code, I found that if you dereference a char pointer in a trace event that happens to point to user space, it can crash the kernel, as it does no checks of that pointer. I have code coming that will do this better, so just remove this ability to treat character pointers in trace events as stings in the histogram. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCYPH9FRQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qsyhAQDKiQzVJtjfsNbIWliDQOaUwJMO9tNl Qu5TUDmPbAA4fwD+MgYsnITPL+o/YcKQ+aMdj/wLLMKfIjhNkFY8wqdLvwg= =CN97 -----END PGP SIGNATURE----- Merge tag 'trace-v5.14-5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing fix from Steven Rostedt: "Fix the histogram logic from possibly crashing the kernel Working on the histogram code, I found that if you dereference a char pointer in a trace event that happens to point to user space, it can crash the kernel, as it does no checks of that pointer.

ARM: dts: versatile: Fix up interrupt controller node names
Once the new schema interrupt-controller/arm,vic.yaml is added, we get
the below warnings:
arch/arm/boot/dts/versatile-ab.dt.yaml:
intc@10140000: $nodename:0: 'intc@10140000' does not match
'^interrupt-controller(@[0-9a-f,]+)*$'
arch/arm/boot/dts/versatile-ab.dt.yaml:
intc@10140000: 'clear-mask' does not match any of the regexes
Fix the node names for the interrupt controller to conform
to the standard node name interrupt-controller@.. Also drop invalid
clear-mask property.

ARM: configs: Update u8500_defconfig
The platform lost the framebuffer due to a commit solving a
circular dependency in v5.14-rc1, so add it back in by explicitly
selecting the framebuffer.
The U8500 has also gained a few systems using touchscreens from
Cypress, Melfas and Zinitix so add these at the same time as
we're updating the defconfig anyway.

There is one larger change in the amd fixes to amalgamate some power management code on the newer chips with the code from the older chips, it should only affects chips where support was introduced in rc1 and it should make future fixes easier to maintain probably a good idea to merge it now. Otherwise it's mostly fixes across the board. dma-buf: - Fix fence leak in sync_file_merge() error code drm/panel: - nt35510: Don't fail on DSI reads fbdev: - Avoid use-after-free by not deleting current video mode ttm: - Avoid NULL-ptr deref in ttm_range_man_fini() vmwgfx: - Fix a merge commit qxl: - fix a TTM regression amdgpu: - SR-IOV fixes - RAS fixes - eDP fixes - SMU13 code unification to facilitate fixes in the future - Add new renoir DID - Yellow Carp fixes - Beige Goby fixes - Revert a bunch of TLB fixes that caused regressions - Revert an LTTPR display regression amdkfd - Fix VRAM access regression - SVM fixes i915: - Fix -EDEADLK handling regression - Drop the page table optimisation" * tag 'drm-fixes-2021-07-16' of git://anongit.freedesktop.org/drm/drm: (29 commits) drm/amdgpu: add another Renoir DID drm/ttm: add a check against null pointer dereference drm/i915/gtt: drop the page table optimisation drm/i915/gt: Fix -EDEADLK handling regression drm/amd/pm: Add waiting for response of mode-reset message for yellow carp Revert "drm/amdkfd: Add heavy-weight TLB flush after unmapping" Revert "drm/amdgpu: Add table_freed parameter to amdgpu_vm_bo_update" Revert "drm/amdkfd: Make TLB flush conditional on mapping" Revert "drm/amdgpu: Fix warning of Function parameter or member not described" Revert "drm/amdkfd: Add memory sync before TLB flush on unmap" drm/amd/pm: Fix BACO state setting for Beige_Goby drm/amdgpu: Restore msix after FLR drm/amdkfd: Allow CPU access for all VRAM BOs drm/amdgpu/display - only update eDP's backlight level when necessary drm/amdkfd: handle fault counters on invalid address drm/amdgpu: Correct the irq numbers for virtual crtc drm/amd/display: update header file name drm/amd/pm: drop smu_v13_0_1.c|h files for yellow carp drm/amd/display: remove faulty assert Revert "drm/amd/display: Always write repeater mode regardless of LTTPR" ... |
