Pb Docker RHEL CentOS 5 et 6

Voir : Kernel Linux syscall

$ docker run --rm -ti centos:centos5 /bin/bash
[139] $

$ docker run --rm -ti centos:centos6 /bin/bash 
[139] $

Impossible de lancer la plupart des commandes. Code de retour d'erreur : 139

Solution

Sur le hôte passer au Kernel Linux l'argument suivant :

vsyscall=emulate

La version de la glibc est trop ancienne et utilise dans anciens appels système !?

Exécutez la commande suivante pour vérifier que votre système a désactivé vsyscall:

cat /proc/self/maps | egrep 'vdso|vsyscall'

La sortie sera semblable à ce qui suit:

7fffccfcc000-7fffccfce000 r-xp 00000000 00:00 0                          [vdso]

ou à celui-ci:

7fffe03fe000-7fffe0400000 r-xp 00000000 00:00 0                          [vdso]
ffffffffff600000-ffffffffff601000 r-xp 00000000 00:00 0                  [vsyscall]

	vsyscall=	[X86-64,EARLY]
			Controls the behavior of vsyscalls (i.e. calls to
			fixed addresses of 0xffffffffff600x00 from legacy
			code).  Most statically-linked binaries and older
			versions of glibc use these calls.  Because these
			functions are at fixed addresses, they make nice
			targets for exploits that can control RIP.

			emulate     Vsyscalls turn into traps and are emulated
			            reasonably safely.  The vsyscall page is
				    readable.

			xonly       [default] Vsyscalls turn into traps and are
			            emulated reasonably safely.  The vsyscall
				    page is not readable.

			none        Vsyscalls don't work at all.  This makes
			            them quite hard to use for exploits but
			            might break your system.
