[Qemu-block] [PATCH 0/2] Remove need for -iscsi argument

[Daniel P. Berrange]

This small series removes the need for using the -iscsi argument
by directly supporting all the -iscsi options against the block
device config eg instead of

$QEMU \
  -object secret,id=sec0,data=123456 \
  -drive driver=iscsi,file=iscsi://catbus/iqn.fedora:kvm/2 \
  -iscsi initiator-name=fish,user=test,password-secret=sec0,timeout=234 

you can now do it all against -drive

$QEMU \
  -object secret,id=sec0,data=123456 \
  -drive driver=iscsi,file=iscsi://catbus/iqn.fedora:kvm/2,\
         initiator-name=fish,user=test,password-secret=sec0,timeout=234 

This fixes the problem that you cannot associate -drive instances
with -iscsi args reliably due to IQNs containing chracters that
QEMU forbids in QemuOpts ID strings.

Pino had previously sent a patch to do this for initiator-name
back in the 2.6 dev cycle

This series supports all the -iscsi option names, except for
'password' which is intentionally left out as it is insecure
and replaced by 'password-secret'.

Daniel P. Berrange (2):
  iscsi: reduce code duplication parsing -iscsi opts
  iscsi: support most -iscsi opts against block dev opts
