Illegal Instruction auf Dell Hardware

Hallo liebes Forum,
wir haben seit kurzem ein Problem mit OpenBSD 7.5 und 7.6 auf Dell Hardware.
Die instbin Binary wirft zuverlässig einen Fehler Illegal instruction (core dumped), allerdings nur auf Dell Hardware - auf allen anderen Plattformen sind uns keine Probleme bekannt.

Wenn wir die Binary mitsamt des Coredumps analysieren, bekommen wir folgende Informationen:

Code:
Core was generated by `instbin'.
Program terminated with signal 4, Illegal instruction.
#0  0x0000000000418bd4 in ?? ()

(gdb) run
(gdb) bt
#0  0x0000000000419114 in ?? ()
#1  0x0000000000283bed in ?? ()
#2  0x0000000000000000 in ?? ()


Ist eventuell bereits jemand auf dieses oder ein ähnliches Problem gestoßen, oder hat eine Idee wie wir das weiter eingrenzen können?

Falls ich noch weitere Infos bereitstellen kann, bitte Bescheid geben.

Moin,

Dell produziert ja nun schon seit 20,30 Jahren oder mehr Hardware - was ist es denn genau? ;)

Magst du evtl. auch kurz beschreiben was instbin noch gleich macht? So richtig klingelst da gerade nicht
 
Wann genau kommt denn dieser core dump? Direkt bei der Installation? Wurde die instbin mit aktuellen sourcen auf einem aktuellen System gebaut oder ist das ein fertiges binary aus offizieller Quelle? Hast Du evtl. ein paar mehr Infos und Daten zur Dell Hardware? Welcher Prozessor, usw.? Evtl. sogar ein dmesg?
 
Seit OpenBSD 7.4 ist z.B. BTI (Branch Target Identification) per default aktiv. Ab der 11. Intel CPU Generation (Tiger Lake) muss beim compilieren das linker-flag -Wl,-z,nobtcfi verwendet oder es muss der code angepasst werden. Aeltere Prozessoren betrifft das nicht, da die noch kein BTI kennen. Evtl. liegt der Fehler irgendwo in dieser Richtung. Ich weiss allerdings nicht, ob das auch bei instbin greift.

7.4
Enable indirect branch tracking (IBT) on amd64 and branch target identification (BTI) on arm64 in both the kernel and in userland. On hardware that supports this feature, it helps enforcing control flow integrity by making sure malicious code cannot jump into the middle of a function.

7.5
Introduce pinsyscalls(2): The kernel and ld.so(1) register the precise entry location of every system call used by a program, as described in the new ELF section .openbsd.syscalls inside ld.so and libc.so. ld.so uses the new syscall pinsyscalls(2) to tell the kernel the precise entry location of system calls in libc.so. Attempting to use a different system call entry instruction to perform a non-corresponding system call operation will fail and the process will be terminated with signal SIGABRT.
 
Zuerst ein herzliches Dankeschön für die Antworten.

Wegen der Hardware habe ich unten die Infos aus der dmesg zurückgegeben.

Für ein einfacheres Beispiel als das instbin (das ein spezielles File ist).
Habe ich das gleiche Problem beim Bauen von ksh:
Code:
delltest# ./distrib/special/ksh/ksh

Mach nochmal ein
Code:
ldd ksh
bitte.
Mein Verdacht ist gerade, dass eine von deinen Libraries kaputt ist.
Da sollte dann sowas bei rauskommen:

Code:
 ldd /usr/local/bin/bash
/usr/local/bin/bash:
    Start            End              Type  Open Ref GrpRef Name
    000006d02b527000 000006d02b67b000 exe   1    0   0      /usr/local/bin/bash
    000006d250a1c000 000006d250a98000 rlib  0    1   0      /usr/lib/libcurses.so.15.0
    000006d249478000 000006d24949c000 rlib  0    1   0      /usr/local/lib/libintl.so.8.0
    000006d267d4c000 000006d267e5e000 rlib  0    2   0      /usr/local/lib/libiconv.so.7.1
    000006d23453f000 000006d234646000 rlib  0    1   0      /usr/lib/libc.so.100.3
    000006d277769000 000006d277769000 ld.so 0    1   0      /usr/libexec/ld.so

Und dann schicke uns doch bitte mal die md5 summen der einzelnen Libraries.
Vielleicht hat ja noch jemand OpenBSD 7.5 am Start und kann die Pruefsummen vergleichen?
 
Oder am besten readelf nutzen, da ldd boesartigen Code im binary ausfuehren kann. Um am Beispiel von dettus mit bash zu bleiben:
Code:
$ readelf -d `which bash` | grep hare
 0x0000000000000001 (NEEDED)             Shared library: [libcurses.so.15.0]
 0x0000000000000001 (NEEDED)             Shared library: [libintl.so.8.1]
 0x0000000000000001 (NEEDED)             Shared library: [libiconv.so.7.1]
 0x0000000000000001 (NEEDED)             Shared library: [libpthread.so.27.1]
 0x0000000000000001 (NEEDED)             Shared library: [libc.so.100.3]

Bist Du sicher, dass dein source code aktuell ist? Sprich die Code-Version auch mit der OS-Version uebereinstimmt?

Du koenntest mal ein ktrace erstellen:
Code:
# ktrace ./distrib/special/ksh/ksh
# kdump -f ktrace.out > ksh.kdump
Und dann die letzten Zeilen des ksh.kdump hier posten. Da sieht man evtl. auch die illegale Instruction, welche zum crash fuehrt.
 
Am ende der ksh.kdump:
Code:
...
 15967 ksh      RET   sigaction 0
 15967 ksh      CALL  sigaction(SIGHUP,0x74f0e5580d68,0)
 15967 ksh      STRU  struct sigaction { handler=0x229812, mask=0<>, flags=0<> }
 15967 ksh      RET   sigaction 0
 15967 ksh      PSIG  SIGILL SIG_DFL code=ILL_BTCFI addr=0x22b5c1 trapno=21
 15967 ksh      NAMI  "ksh.core"

Ich glaube hier ist der "ILL_BTCFI" das Problem?

ldd von /usr/src/distrib/special/ksh aus gibt zurück:
Code:
not a dynamic executable

Es ist, soweit ich weiß eine "Vanilla" Installation von openBSD, wo ich versuche das ksh von RAMDISK_CD zu bauen, und nicht auf "normale" ksh.

readelf:
Code:
delltest# readelf -d `which bash` | grep hare
 0x0000000000000001 (NEEDED)             Shared library: [libcurses.so.15.0]
 0x0000000000000001 (NEEDED)             Shared library: [libintl.so.8.0]
 0x0000000000000001 (NEEDED)             Shared library: [libiconv.so.7.1]
 0x0000000000000001 (NEEDED)             Shared library: [libc.so.99.0]
 
Ja genau. BTI ist seit 7.4 aktiv, wenn deine CPU das unterstuetzt. Sind deine source codes aktuell bzw. auf dem Stand der jeweiligen OpenBSD-Version? Dann sollte das Base-System ohne Probleme kompilieren. Hast Du evtl. compiler flags in der /etc/mk.conf, die Probleme bereiten? Welchen Compiler nutzt Du? Der aus base oder einen aus den ports? Ansonsten kannst Du mal probieren, dein Makefile um das flag -Wl,-z,nobtcfi zu erweitern. Das sollte bei einem synchronen und sauberen Base-System allerdings nicht notwendig sein. RELEASE(8) gibt auch noch ein paar Hinweise.

Ich vermute, dass die ksh der RAMDISK_CD aus Platzmangel oder Kompatibilitaetsgruenden nicht die Aenderungen fuer BTI im Code integriert hat und der compiler daher die Fehlermeldung ausgibt und abbricht, wenn er einen indirekten Sprung oder Aufruf entdeckt. Vermutlich wird das auf einem aelteren System gebaut oder durch entsprechende compiler flags beim Bauen deaktiviert.

Vielen Dank midnight!

Ich habe die Flags in /etc/mk.conf hinzugefügt und es hat funktioniert.

Nur zum Verständnis: Ich finde es komisch, dass die ksh aus dem openbsd-Image korrekt funktioniert, aber nicht, wenn man sie selbst kompiliert. Kann man sehen, mit welchen Flags es gelinkt wurde?
Und dann, von den oben genannten Flags, was machen -Wl und -z?

Nochmals vielen Dank!

Gern, freut mich, dass es geklappt hat. :-)
Nur zum Verständnis: Ich finde es komisch, dass die ksh aus dem openbsd-Image korrekt funktioniert, aber nicht, wenn man sie selbst kompiliert. Kann man sehen, mit welchen Flags es gelinkt wurde?
Dazu kann ich dir nichts genaues sagen. Vermutlich sind entsprechende linker flags in irgendwelchen Makefiles beim builden von release(8) definiert oder irgendwo in /usr/share/mk/ versteckt. Evtl. fragst Du mal in der OpenBSD-Mailingliste oder im irc nach.
Und dann, von den oben genannten Flags, was machen -Wl und -z?
Code:
-Wl,<arg>               Pass the comma separated arguments in <arg> to the linker
-z <arg>                Pass -z <arg> to the linker
nobtcfi ist dann das <arg> zum Deaktivieren von BTI beim Kompilieren. Genaues weiss ich auch nicht. Habs im Internet zu diesem Thema bezueglich OpenBSD gefunden.
