Re: [libvirt] [BUG] storage.xml: owner|group=-1 → 2^32-1 on 32 Bit

Hello, when you install and use libvirt in a 32 bit environment, the handling of owner and group in /etc/libvirt/storage/*.xml is broken: The initial -1 is printed as an "unsigned int" and is thus converted to +(2^32-1):

When you next restart libvirtd virStorageDefParsePerms() tries to parse that as an "signed int", which fails in virXPathLongBase() because of > 182 if (*value != obj->floatval) { > (gdb) print *value > $11 = -2147483648 > (gdb) print obj->floatval > $12 = 4294967295 > (gdb) print /x *value > $13 = 0x80000000 > (gdb) print /x obj->floatval > $14 = 0xffffffff This then prints the following error messages: > 2012-11-23 14:03:18.877+0000: 25536: error : virStorageDefParsePerms:613 : > XML error: malformed owner element > 2012-11-23 14:03:19.581+0000: > 25529: error : storagePoolSetAutostart:1056 : Failed to create symlink > '/etc/libvirt/storage/autostart/default.xml' to '/etc/libvirt/storage/def The change to print owner and group as %d instead of %u was introdeces in commit 37a10129: > Update xml schemas according to libvirt source ... > storage_conf: Print uid_t and gid_t as signed to storage pool XML. Care to revert that change? Patch is attached. Sincerely Philipp -- libvir-list mailing list libvir-list(a)redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
