[Behoben] Brickd bricht zusammen (arm 2.1.0)

Loetkolben · July 12, 2014 at 11:46

Hallo zusammen,

habe hier einen Cubietruck (A20) mit dem Brickd seit Monaten nonstop am laufen. Minuetlich greifen andere Rechner auf den Stack zu. Alles ok.

Gestern habe ich zusaetzlich von einem weit entfernten Rechnen den Brickv gestartet und die neue LED Funktion getestet. Ich habe die LED hin und her laufen lassen und ploetzlich (Nach Minuten bzw. Stunden, aber ohne erkennbaren Grund) ist der brickd zusammengebrochen. Warum?

Im zweiten Beispiel habe ich an der Situation nichts veraendert, aber die Logfiles sehen anders aus. Vielleicht haengt es bei diesem mal damit zusammen, dass der weit entfernte Brickv in der Nacht vielleicht mal nicht erreichtbar war. (Providerprobleme)

Diese beiden Zeilen sind interessant:

2014-07-12 05:10:14.277472 <E> <network|client.c:260> Could not receive from client (S: 7281224, T: plain, P: P^Mo, A: disabled), disconnecting client: EBADF (9)

"S: 7281224" heißt der File Descriptor des Sockets diese Clients hat einen Wert von 7281224, das ist sehr hoch und ungewöhnlich, daher kommt da dann auch ein EBADF (ungültiger File Descriptor) als Fehler bei rum.

"P: PTî¶PTî¶23.81" ist der Peername des Clients, da sollte eine IP Adresse stehen, das sieht aber nach Schrott aus.

Das sieht auf den ersten Blick nach Heap Corruption aus. Irgendwie bringst du brickd dazu irgendwo falsch im Speicher herumzuschreiben.

Kannst du das Problem reproduzieren? Es wäre hilfreich dazu ein Valgrind Log zu sehen. Dazu brickd manuell mit Valgrind starten:

sudo valgrind brickd

Loetkolben · July 14, 2014 at 13:34

Hallo photron,

reproduzieren kann ich es im Prinzip "nicht", aber es tritt immer wieder auf.

Nochmals zur Erinnerung: Der brickd hat 2 Monate problemlos gelaufen. Erst als ich mit dem Brickv von einem anderen Recher "dazwischengefunkt" habe ist das passiert.

Hier der letzte Absturz:

Okay, ich erwarte das Valgrind Invalid Read oder Write Operationen meldet wenn das Problem auftritt. Die Ausgabe von Valgrind dazu mit samt den Backtraces interessiert mich, um zu sehen wo das Problem her kommt.

Ich habe mit deine Logs nochmal angesehen und zwei Dinge sind mir aufgefallen. Die letzten zwei Logausgabe bevor das Problem auftritt sind immer:

2014-07-11 21:22:16.454644 <I> <network|client.c:242> Client (S: 20, T: plain, P: 192.168.23.81, A: disabled) disconnected by peer

Ein Client schließt seine Verbindung bevor brickd im alle Response Pakete schicken konnte.

Auch ist auffällig, dass kurz vorher viele Verbindungen in sehr kurzer Zeit geschlossen werden:

2014-07-12 05:10:14.060499 <I> <network|client.c:242> Client (S: 44, T: plain, P: 192.168.23.81, A: disabled) disconnected by peer

Da frage ich mich gerade wie das zustande kommt. Wie lange bleiben die Verbindungen der minütlich zugreifenden anderen Rechner bestehen?

Loetkolben · July 14, 2014 at 14:27

Hallo photron,

"dazu mit samt den Backtraces"? Wo werden die stehen?

Also die verschiedenen Rechner machen eigentlich nur "eine Sekunde" die Verbindung auf.

Zum einen machen minuetlich verschiedene Rechner die LEDs an dem IO-16 aus (Port setzen),

zum anderen wird minuetlich die Temperatur gelesen und

stuendlich Temperatur, Humidity und Light.

Parallel dazu laueft im Moment der Brickviewer mit dem LED Test.

Hier mal die gerade kompletten Logs von 3 Minuten:

Sorry, das was ungeschickt formuliert. Valgrind gibt das alles an einem Stück aus, das sieht dann z.B. so aus:

==19182== Invalid write of size 4
==19182==    at 0x804838F: f (example.c:6)
==19182==    by 0x80483AB: main (example.c:11)
==19182==  Address 0x1BA45050 is 0 bytes after a block of size 40 alloc'd
==19182==    at 0x1B8FF5CD: malloc (vg_replace_malloc.c:130)
==19182==    by 0x8048385: f (example.c:5)
==19182==    by 0x80483AB: main (example.c:11)

Das Log sieht jetzt aus wie ich es erwarten würde, nach deiner Beschreibung. Connect und Disconnect schön abwechselnd.

Im Fehlerfall sind dann aber im Log Häufungen von Disconnects, was ich komische finde. Das passt nicht so wirklich zum beschriebenen Verhalten deines Aufbaus.

Hallo photron,

ich habe nichts gemacht, ausser den LEDs zuzusehen. :-)

In der Minute :05 kommen wieder diese "disconnects", aber alles funktioniert weiterhin.

Sorry fuer die langen Logfiles, aber das meiste kann man ja uebersehen.

Warten wir mal ab. ...

[Alles funktioniert noch]

Edit:

Kann es sein, dass pro Minute ein "Added new client" mehr hinzukommt, als dass es "disconnects" gibt?

Kann es sein, dass die ueberzaehligen "Added new client" irgendwann am Stueck abgebaut werden?

Das muesste ja irgendwo in meiner Logik liegen, aber ich wuesste nicht wo?!

Aber egal, der bickd sollte nicht abstuerzen. Warten wir mal weiter ab.

Laufen die Programme die die Anfragen machen durch oder startest du die für jede Anfrage neu?

Wenn dein Programm durchläuft und ab und zu "vergisst" Sockets/IPConnections wieder zu schließen, dann könnte sich so eine Liste offener Verbindungen ansammeln. Diese würden dann vom Betriebssystem wieder geschlossen, wenn das Programm beendet wird.

Da ich aber annehme, dass du das Protokoll von Hand mit einzelnen netcat Aufrufen sprichst kann das eigentlich nicht das Problem sein.

Loetkolben · July 14, 2014 at 16:17

Hallo photron.

Ich mache pro Anfrage eine neue Verbindung auf, bzw. ich nutze nc (netcat).

Es kann aber sein, dass ich bei "set" Befehlen keine Antwort verarbeite, da keine Antwort definiert ist.

Aber hier die neuesten Entwicklungen. Ploetzlich ging es los. S.u. Den Anfang dieses rasenden Durchscrollens habe ich nicht, da ueber 100 Meldungen pro Sekunde im Moment hier durchlaufen. Erstaunlicherweise funktioniert noch alles. Die LEDs gehen aus (IO-16) und der Colortest laeuft bunt durch.

Soll ich mal mit einem CTRL-C abbrechen und neu starten?

==24206== ERROR SUMMARY: 10000000 errors from 15 contexts (suppressed: 25 from 9)

10000000 Errors!

Da ist irgendwas oberfaul. Es ist vom Aufbau von brickd her nicht möglich das diese Fehlermeldung zweimal für den gleichen Socket auftritt. Auch das es Fehlercode EBADF ist ist mit höchst Suspekt.

Ich könnte mir vorstellen es reicht an einer Stelle passend eine der Datenstrukturen von brickd zu zerschreiben, dabei diese Problem zu erzeugen, den Rest aber weiterlaufen zu lassen.

Starte Valgrind mal mit Logfile, damit dessen Ausgaben nicht in der Menge von brickd Meldungen verloren gehen:

sudo valgrind --log-file=valgrind.log brickd

Hallo photron.

Starte Valgrind mal mit Logfile, damit dessen Ausgaben nicht in der Menge von brickd Meldungen verloren gehen:

So, neu gestartet.

Ich hatte bisher keine valgrind Meldungen ausser am Start und am CTRL-C Ende gesehen. Was beim Start des Massenlogs passierte konnte ich nicht sehen. Auch der Scrollback im Terminalfenster war nicht gross genug.

Mal sehen ...

Ich werde den brickd jetzt als "/etc/init.d/brickd start" starten und schauen was passiert.

Okay, da sind einige Invalid Reads zu erkennen im Valgrind Log. Leider kann Valgrind mit der brickd Version aus dem Debian Package keinen ordentlichen Backtrace erzeugen, so dass man sehen kann wo im Code das Problem ist. Daran hatte ich vorher nicht gedacht, sorry.

Kannst du brickd selber kompilieren, so dass es Symbols usw. hat damit Valgrind besser anzeigen kann wo das Problem ist? Hier wie's geht:

sudo apt-get install build-essential pkg-config libusb-1.0-0-dev libudev-dev pm-utils
wget https://github.com/Tinkerforge/brickd/archive/v2.1.0.zip
unzip v2.1.0.zip
cd brickd-2.1.0/src/brickd
CFLAGS=-g\ -ggdb make

Danach liegt im aktuellen Verzeichnis der neue brickd. Und dann nochmal mit Valgrind:

sudo valgrind --time-stamp=yes --log-file=valgrind.log ./brickd

Zeitliche Zuordnung der Valgrind und brickd Ausgaben ist nicht unbedingt nötig, wenn Valgrind mir sagt wo im Code das Problem ist sollte das reichen, um es verstehen und beheben zu können. Aber es schadet nicht Valgrind einen Timestamp im Log ausgeben zu lassen. Der ist aber im Gegensatz zu brickd relative zur Startzeit von Valgrind.

So, erledigt. Abbruch des neu compilierten brickd. Danke fuer die passenden Compileschritte!

Was mich stutzig mach: Alles hat 2 Monate problemlos gelaufen. Dann gab es bei dem LED Bricklet Test diese Probleme. Bei den letzten beiden Abbruechen habe ich nicht mehr mit dem Brickviewer zugegriffen, sondern alles so gelassen wie es die letzten 2 Monate war. Wo liegt das Problem? Der Rechner ist nicht durchgebootet worden. Das ist aber auch Absicht.

Ahhhhh, jetzt weiß ich was los ist. Das ist ein Problem, dass im git schon behoben habe. Allerdings habe ich die Folgen diese Problems wohl nicht richtig beurteilt, sonst gäbe es schon brickd 2.1.1 in der es behoben wäre, sorry.

Hier die Schritte den Patch dafür zu testen:

cd brickd-2.1.0/src/brickd
sudo apt-get install patch
wget https://github.com/Tinkerforge/brickd/commit/442321f6d6619c0ff80770776f108d50dc53e6e2.patch
patch -p3 < 442321f6d6619c0ff80770776f108d50dc53e6e2.patch
CFLAGS=-g\ -ggdb make

Dann kannst du wieder testen, das Problem sollte nicht mehr auftreten.

Der Auslöser ist, dass der Client disconnected, wenn im Send Queue noch Antworten für den Client sind. In diesem Fall wird der Socket des Clients nicht richtig aus dem Event Loop entfernt. Was im Endeffekt dann dazu führt, dass Funktionen für einen Client aufgerufen werden, dessen Speicher schon längst freigegeben wurde => Crash.

Es wird dann in Kürze eine neu brickd Version geben.

Warum das Problem erst jetzt auftritt mag damit zusammenhängen, dass sich das Timing deines ganzen Aufbaus vielleicht etwas verändert hat, oder sich die Belastung etwas geändert hat, so dass es jetzt vorkommt, dass Clients disconnecten wenn brickd noch Antworten für sie hat.
