I think everything should be there. I thought I worked on iser when

In the other mails I think I said you need a change to the userspace
iser code, but ignore that. In the common iscsi code I did a hack for
all drivers.
Apply the patch and then run
iscsiadm -m discovery -t st -p ip -I iser -d 8
In the userspace discovery.c:iscsi_create_leading_conn() you will want
to check that the code path with this debug log statement is being hit:
log_debug(2, "%s discovery ep connect\n", __FUNCTION__);
and that it is the correct callout for your driver.
Mike,
I had some troubles building the user space part of the initiator from
the latest git, FWYI - for utils/open-isns./configure
--without-securityworks OK, but the default (which is --with-security)
seems to be broken (see below). Also once, I passed that, I failed to
get the usr directory utils to get built as of missing strlcpy/strlcat
-- probably my glibc is too old and doesn't contain these folks... do
you know of the latest initiator is buildable on RHEL 6.x nodes (e.g
with glibc-2.12-1.47.el6.x86_64) ?

another failure I see there is for the fw_xxx functions, any idea what
should I build to make that work?
