Subject: [Qemu-devel] [PATCH] linux-user, s390x: ignore OS ABI value in ELF header
Date: Fri, 10 Nov 2017 20:49:35 +0100 [thread overview]
Message-ID: <20171110194935.17541-1-laurent@vivier.eu> (raw)
I have this error:
bash: /sbin/ldconfig: cannot execute binary file: Exec format error
because /sbin/ldconfig is:
ELF 64-bit MSB executable, IBM S/390, version 1 (GNU/Linux),
statically linked, for GNU/Linux 3.2.0,
BuildID[sha1]=90b64604014aafac9c1a0623b1cf447281d1a382, stripped
OS ABI is GNU/linux
"/bin/ls" works well:
ELF 64-bit MSB shared object, IBM S/390, version 1 (SYSV), dynamically linked,
interpreter /lib/ld64.so.1, for GNU/Linux 3.2.0,
BuildID[sha1]=be9b19143d4657678846f6e5277383071fc1059a, stripped
OS ABI is SYSV
To be able to execute ldconfig, this patch modifies s390x binfmt mask
to ignore the OS ABI value (EI_OSABI, byte 7).
