Re: [Xen-users] Open-iSCSI

["Angel Lopez" <angel@xxxxxxxxxx>]

Hi,

It seems that my problem is the CRC checking for module versions in
/lib/modules/`uname -r`/build/Module.symvers are diferent from the
versions of the Open-iSCSI modules (iscsi_tcp.ko, libiscsi.ko and
scsi_transport_iscsi.ko) that I have built.

Before installing Open-iSCSI:

# nm /lib/modules/`uname -r`/kernel/drivers/scsi/libiscsi.ko | grep
iscsi_conn_setup
a884cb50 A __crc_iscsi_conn_setup
00001aeb T iscsi_conn_setup
00000048 r __kcrctab_iscsi_conn_setup
0000018e r __kstrtab_iscsi_conn_setup
00000090 r __ksymtab_iscsi_conn_setup

# grep iscsi_conn_setup /lib/modules/`uname -r`/build/Module.symvers
0xa884cb50      iscsi_conn_setup        drivers/scsi/libiscsi  
EXPORT_SYMBOL_GPL

After installing Open-iSCSI:

# nm /lib/modules/`uname -r`/kernel/drivers/scsi/libiscsi.ko | grep
iscsi_conn_setup
4184140d A __crc_iscsi_conn_setup
00001c14 T iscsi_conn_setup
00000048 r __kcrctab_iscsi_conn_setup
0000018e r __kstrtab_iscsi_conn_setup
00000090 r __ksymtab_iscsi_conn_setup

So I think that I should fix that 4184140d and change it to a884cb50

When you use Open-iSCSI... how do u fix the versions? Is there any script
or something like that?

Thanks.
