Hello all,

I have a strange problem with loading a kernel-module (openafs) built on OBS (package filesystems/openafs16).

The module builds fine and is apparently signed :

dummy0:~ # modinfo /lib/modules/3.12.28-4-default/updates/libafs.ko filename: /lib/modules/3.12.28-4-default/updates/libafs.ko license: http://www.openafs.org/dl/license10.html srcversion: 40263E5014D985AEA7C9C32 depends: vermagic: 3.12.28-4-default SMP mod_unload modversions signer: SUSE Linux Enterprise Secure Boot Signkey sig_key: 3F:B0:77:B6:CE:BC:6F:F2:52:2E:1C:14:8C:57:C7:77:C7:88:E3:E7 sig_hashalgo: sha256

insmod however fails with ERANGE : dummy0:~ # insmod /lib/modules/3.12.28-4-default/updates/libafs.ko insmod: ERROR: could not insert module /lib/modules/3.12.28-4-default/updates/libafs.ko: Numerical result out of range

Unfortunately, ERANGE is not mentioned as a possible errno in the man-page, neither can I find something useful on google.

However, I provide also the kernel-module source as an rpm for people to build the module against custom kernels. This one also builds fine, but it is unsigned : dummy0:~ # modinfo /usr/src/kernel-modules/openafs/libafs_tree/src/libafs/MODLOAD-3.12.28-4-default-MP/libafs.ko filename: /usr/src/kernel-modules/openafs/libafs_tree/src/libafs/MODLOAD-3.12.28-4-default-MP/libafs.ko license: http://www.openafs.org/dl/license10.html srcversion: 40263E5014D985AEA7C9C32 depends: vermagic: 3.12.28-4-default SMP mod_unload modversions

and insmod works : dummy0:~ # insmod /usr/src/kernel-modules/openafs/libafs_tree/src/libafs/MODLOAD-3.12.28-4-default-MP/libafs.ko dummy0:~ # lsmod | grep afs libafs 844736 0

(Actually, the whole openafs-client works).

The only difference I see is the signature of the module.

Is this a bug in OBS or in SLES 12 ? Whom should I contact about this ?

Many thanks,

Christof
