iSCSI: add configuration variables for iSCSI
This patch adds configuration variables for iSCSI to set initiator-name to use when logging in to the target, which type of header-digest to negotiate with the target and username and password for CHAP authentication. This allows specifying a initiator-name either from the command line -iscsi initiator-name=iqn.2004-01.com.example:test or from a configuration file included with -readconfig [iscsi] initiator-name = iqn.2004-01.com.example:test header-digest = CRC32C|CRC32C-NONE|NONE-CRC32C|NONE user = CHAP username password = CHAP password If you use several different targets, you can also configure this on a per target basis by using a group name: [iscsi "iqn.target.name"] ... The configuration file can be read using -readconfig. Example : qemu-system-i386 -drive file=iscsi://127.0.0.1/iqn.ronnie.test/1 -readconfig iscsi.conf Signed-off-by: Ronnie Sahlberg <ronniesahlberg@gmail.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
