ANDROID: ring-buffer: Introducing external writer support
The ring buffer is convenient: it has a page granularity and its format
is already supported by userspace tools such as trace-cmd. It is a
natural solution to store events that would come from outside the kernel
such as a hypervisor.
In that case, where a writer is external to the kernel, the latter would
only be responsible for the allocation and to read back the ring buffer.
The allocation is done with the newly introduced function which just
needs a size and a set of callbacks (notice only the overwrite mode is
supported at the moment):
ring_buffer_alloc_ext(unsigned long size,
struct ring_buffer_ext_cb *cb)
The callbacks given to this allocator enables communication with the
external writer:
(*swap_reader)(int cpu): Ask the writer to swap the current reader
page with the head.
(*update_footers)(int cpu): Ask the writer to update material in the
page footers.
Each page from the ring buffer has indeed a footer in which statistics
and page status can be retrieved. This allows the kernel to update its
view on the ring buffer, following a reader page swap or a footers
update.
After the trace_buffer is allocated, a helper serializes the relevant
information into a structure that can be easily sent to the external
writer:
trace_buffer_pack(struct trace_buffer *trace_buffer,
struct trace_buffer_pack *pack)
The footer and pack description can be found in the newly introduced
header file include/linux/ring_buffer_ext.h.
When the kernel is writing to the ring buffer, it can wake up quite
easily the reader. That's not the case when the writer is external. A
new function allows polling for reading the ring buffer:
ring_buffer_poke(struct trace_buffer *buffer, int cpu)
A ring-buffer allocated for an external writer will forbid any writing
(the whole design of the ring buffer mandates a single writer) and will
also prevent extending or extracting pages.
When I presented this work to the tracingsummit, rosted@ told me he saw
some overlapping with an idea he had to enable him to map the tracing
buffers in userspace. We designed together a solution that would enable
both features. Problem now, if on one hand, the development of the new
design has started already... it would nonetheless impose a significant
revamp of this patchset, which wouldn't make it to Android14. Nothing
technically wrong with anything here, but sending it to LKML wouldn't
make sense, as I know already this isn't as "reusable" as the version
agreed upon.

ANDROID: ring-buffer: Expose buffer_data_page material

The functions get_online_cpus() and put_online_cpus() have been deprecated during the CPU hotplug rework. They map directly to cpus_read_lock() and cpus_read_unlock().

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 ( |

ring-buffer: Add verifier for using ring_buffer_event_time_stamp()
The ring_buffer_event_time_stamp() must be only called by an event that has not been committed yet, and is on the buffer that is passed in. This was used to help debug converting the histogram logic over to using the new time stamp code, and was proven to be very useful. Add a verifier that can check that this is the case, and extra WARN_ONs to catch unexpected use cases.

ring-buffer: Allow ring_buffer_event_time_stamp() to return time stamp of all events
Currently, ring_buffer_event_time_stamp() only returns an accurate time stamp of the event if it has an absolute extended time stamp attached to it. To make it more robust, use the event_stamp() in case the event does not have an absolute value attached to it. This will allow ring_buffer_event_time_stamp() to be used in more cases than just histograms, and it will also allow histograms to not require including absolute values all the time.

ring-buffer: Force before_stamp and write_stamp to be different on discard
Part of the logic of the new time stamp code depends on the before_stamp and
the write_stamp to be different if the write_stamp does not match the last
event on the buffer, as it will be used to calculate the delta of the next
event written on the buffer.
The discard logic depends on this, as the next event to come in needs to
inject a full timestamp as it can not rely on the last event timestamp in
the buffer because it is unknown due to events after it being discarded. But
by changing the write_stamp back to the time before it, it forces the next
event to use a full time stamp, instead of relying on it.
The issue came when a full time stamp was used for the event, and
rb_time_delta() returns zero in that case. The update to the write_stamp
(which subtracts delta) made it not change. Then when the event is removed
from the buffer, because the before_stamp and write_stamp still match, the
next event written would calculate its delta from the write_stamp, but that
would be wrong as the write_stamp is of the time of the event that was
discarded.
In the case that the delta change being made to write_stamp is zero, set the
before_stamp to zero as well, and this will force the next event to inject a
full timestamp and not use the current write_stamp.

Pull tracing updates from Steven Rostedt: "The major update to this release is that there's a new arch config option called CONFIG_HAVE_DYNAMIC_FTRACE_WITH_ARGS. Currently, only x86_64 enables it. All the ftrace callbacks now take a struct ftrace_regs instead of a struct pt_regs. If the architecture has HAVE_DYNAMIC_FTRACE_WITH_ARGS enabled, then the ftrace_regs will have enough information to read the arguments of the function being traced, as well as access to the stack pointer. This way, if a user (like live kernel patching) only cares about the arguments, then it can avoid using the heavier weight "regs" callback, that puts in enough information in the struct ftrace_regs to simulate a breakpoint exception (needed for kprobes). A new config option that audits the timestamps of the ftrace ring buffer at most every event recorded. Ftrace recursion protection has been cleaned up to move the protection to the callback itself (this saves on an extra function call for those callbacks). Perf now handles its own RCU protection and does not depend on ftrace to do it for it (saving on that extra function call). New debug option to add "recursed_functions" file to tracefs that lists all the places that triggered the recursion protection of the function tracer. This will show where things need to be fixed as recursion slows down the function tracer. The eval enum mapping updates done at boot up are now offloaded to a work queue, as it caused a noticeable pause on slow embedded boards.

Revert: "ring-buffer: Remove HAVE_64BIT_ALIGNED_ACCESS"
It was believed that metag was the only architecture that required the ring
buffer to keep 8 byte words aligned on 8 byte architectures, and with its
removal, it was assumed that the ring buffer code did not need to handle
this case. It appears that sparc64 also requires this.
The following was reported on a sparc64 boot up:
kernel: futex hash table entries: 65536 (order: 9, 4194304 bytes, linear)
kernel: Running postponed tracer tests:

ring-buffer: Add test to validate the time stamp deltas
While debugging a situation where a delta for an event was calucalted wrong,
I realize there was nothing making sure that the delta of events are
correct. If a single event has an incorrect delta, then all events after it
will also have one. If the discrepency gets large enough, it could cause
the time stamps to go backwards when crossing sub buffers, that record a
full 64 bit time stamp, and the new deltas are added to that.
Add a way to validate the events at most events and when crossing a buffer
page. This will help make sure that the deltas are always correct. This test
will detect if they are ever corrupted.
The test adds a high overhead to the ring buffer recording, as it does the
audit for almost every event, and should only be used for testing the ring
buffer.
This will catch the bug that is fixed by commit

ring-buffer: Always check to put back before stamp when crossing pages
The current ring buffer logic checks to see if the updating of the event
buffer was interrupted, and if it is, it will try to fix up the before stamp
with the write stamp to make them equal again. This logic is flawed, because
if it is not interrupted, the two are guaranteed to be different, as the
current event just updated the before stamp before allocation. This
guarantees that the next event (this one or another interrupting one) will
think it interrupted the time updates of a previous event and inject an
absolute time stamp to compensate.
The correct logic is to always update the timestamps when traversing to a
new sub buffer.

write_stamp via local_cmpxchg(); in this case the delta is not valid

ring-buffer: Fix recursion protection transitions between interrupt context
The recursion protection of the ring buffer depends on preempt_count() to be
correct. But it is possible that the ring buffer gets called after an
interrupt comes in but before it updates the preempt_count(). This will
trigger a false positive in the recursion code.
Use the same trick from the ftrace function callback recursion code which
uses a "transition" bit that gets set, to allow for a single recursion for
to handle transitions between contexts.

Pull tracing updates from Steven Rostedt: - The biggest news in that the tracing ring buffer can now time events that interrupted other ring buffer events. Before this change, if an interrupt came in while recording another event, and that interrupt also had an event, those events would all have the same time stamp as the event it interrupted. Now, with the new design, those events will have a unique time stamp and rightfully display the time for those events that were recorded while interrupting another event. - Bootconfig how has an "override" operator that lets the users have a default config, but then add options to override the default. - A fix was made to properly filter function graph tracing to the ftrace PIDs.
