heap corruption (malloc/free errors) presumably during calibration

[kolyshkin]

• I confirm that this is an issue rather than a question.

Bug report

I was calibrating my LED string via web interface and noticed it became unresponsive. Checked system logs and found some messages hinting towards libc heap corruption (see below).

Steps to reproduce

Invoke "colour calibration wizard" via web interface. Play with settings.

What is expected?

No errors in log, web interface and led string is responsive while changing calibration values.

What is actually happening?

In one case, changing RGB values for a color stopped making any effect on LED string.
In another case, web server thread is gone (i.e. hyperiond no longer listens on port 9100).

System logs show:

hyperiond process is active (and LED lights react to changes in the v4l input), but it no longer listens on port 9100:

So, these messages

Dec 30 20:59:22 HyperBian hyperiond[466]: free(): corrupted unsorted chunks

Dec 30 22:18:04 HyperBian hyperiond[1118]: malloc(): unsorted double linked list corrupted

suggest heap corruption, while

Dec 30 21:00:32 HyperBian kernel: Out of memory: Killed process 466 (hyperiond) total-vm:737392kB, anon-rss:393160kB, file-rss:2400kB, shmem-rss:0kB, UID:0 pgtables:578kB oom_score_adj:0

suggest memory leaks.

[kolyshkin]

It took about 30 minutes of playing with calibration settings (since a fresh restart) until I got this again:

Dec 31 00:17:50 HyperBian hyperiond[5912]: malloc(): unsorted double linked list corrupted
Dec 31 00:17:50 HyperBian hyperiond[5912]: Hyperion caught signal :SIGABRT

so it is definitely related to calibration. Note that v4l capture and LED still works, it just does not react to changing calibration settings.

Had to sudo systemctl restart hyperion to continue calibration (glad that I wrote done all the values I got so far).

[kolyshkin]

Using mcheck(3) is not an option since it's not compatible with threaded apps.

I tried using valgrind/memcheck in 3 different configuration

1. RasPi Zero CPU. It seems to be too slow for valgrind, all I see is 100% CPU usage and no web server appearing (which might actually be a manifestation of Hyperbian image fails to start web service out of the box #1090).
2. On my Linux PC, self-compiled. I see some issues but nothing during the calibration (I tried changing values for a few minutes, but not half an hour).
3. Inside qemu-system-arm64. It is even slower than RasPI Zero :(

I guess I'll have to invest into a faster Pi.

[kolyshkin]

Ran a self-built debug version under gdb on a Pi 4 model B.

1. Set LED controller to ws2812spi.
2. Set LED layout to 'top: 200, bottom: 200, left: 120, right: 120'.
3. Went to "color calibration wizard" and randomly changed number in white and red light.

Got this in a few minutes:

@kolyshkin Thanks for reporting!
Would you mind sharing a screenshot of your LED-Device configuration with Expert Setting level on?
Does the issue occur, if you change the color via the "Remote Control" screen, too?

Would you mind sharing a debug log, too? From startup to failure... (or until you start the test)

[patriot1889]

I feel this is related to the bug I reported a while ago

#1094

I am unable to complete a calibration due to this.

[Lord-Grey]

@patriot1889 / @kolyshkin Are you able to reproduce it consistently with alpha9?
I tried to "just click around" via the Wizard (as in the problem descriptions), but was to successful triggering the failure event.
In case there is a sceanrio where you deterministically can create the abort, that would be really helpful....

Would you mind sharing your configuration? Just do an export of the configuration via the UI.

[patriot1889]

@patriot1889 / @kolyshkin
a) Do you have "Smoothing" on or off when running into this problem?
b) How many LED have you configured?

Smoothing on I believe, 90 LEDs total.
