Description of problem:
Can't start iscsid in a docker container
Version-Release number of selected component (if applicable):
# rpm -q docker-io
docker-io-0.11.1-3.fc20.x86_64
How reproducible:
always
Steps to Reproduce:
1. use the published fedora image, docker pull fedora
2. start the container, docker run -t -i fedora /bin/bash
3. install iscsi-initiator-utils
4. try to start iscsid:
bash-4.2# iscsid -f
iscsid: can not bind NETLINK_ISCSI socket
strace also attached
--- Additional comment from James Slagle on 2014-05-21 14:45:57 EDT ---
To give a little more context into what I'm doing, I'm trying to run OpenStack
nova compute configured to use the nova-baremetal driver inside a container.
when nova-baremetal provisions a machine it acts as an iscsi initiator and logs
into a target that has been created on the machine that is being provisioned.
It then dd's the requested image onto the disk.
therefore, aiui, iscsid must be running inside the container where you are also
running iscsiadm.
This same thing has also been tried in lxc, with what I expect is the same
issue:
https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1226855
--- Additional comment from Daniel Walsh on 2014-05-28 12:29:35 EDT ---
Was SELinux involved? If you put the machine into permissive mode does it
work? Or try this as a privleged image. Might be something that we are doing
to lock the system down.
--- Additional comment from Daniel Walsh on 2014-05-28 12:33:18 EDT ---
What are the permissions on /opt/hello
ls -ld /opt
ls -ld /opt/hello
--- Additional comment from James Slagle on 2014-05-28 15:01:53 EDT ---
SELinux is already in permissive mode on the Docker host.
I did try in a privileged container, and I get something slightly different.
iscsid -f just hangs forever on the command line.
An strace shows (attached) it polling forever on a fd, i had to ctrl-c it in
both cases.

--- Additional comment from James Slagle on 2014-05-28 15:03:16 EDT ---
i think comment 3 was for another bug maybe? anyway, if not:
bash-4.2# ls -ld /opt
drwxr-xr-x. 2 root root 4096 Aug 7 2013 /opt
bash-4.2# ls -ld /opt/hello
ls: cannot access /opt/hello: No such file or directory
--- Additional comment from James Slagle on 2014-05-28 15:08:58 EDT ---
ah....actually, i suspect iscsid running forever in the foreground may indicate
it *is* working. sorry, i wasn't thinking that -f was telling it to run in the
foreground.
i will see if i can actually connect to a target from the privileged container
and report back
--- Additional comment from James Slagle on 2014-05-29 09:34:32 EDT ---
I'm using a privileged container running sshd as the process (so that I can
login with a couple of different shells),
I had to add this to my Dockerfile for the container, otherwise iscsid won't
start:
VOLUME ["/var/lock/iscsi"]
i start the conatiner with:
docker run --privileged -ti --name initiator -p 8022:22 -d iscsi-initiator
then ssh in, and i start iscsid:
iscsid -d 8 -f
that appears to start fine
then ssh in another session, and i can discover the target (target is actually
on the container host):
[root@bcf697cb8673 ~]# iscsiadm -m discovery -t st -p 192.168.122.1
192.168.122.1:3260,1 iqn.2013-07.com.example.storage.ssd1
but when i try to login to the target, iscsid exits (or crashes, hard to tell):
[root@bcf697cb8673 ~]# iscsiadm -m node --targetname
iqn.2013-07.com.example.storage.ssd1 --portal 192.168.122.1 --login
Logging in to [iface: default, target: iqn.2013-07.com.example.storage.ssd1,
portal: 192.168.122.1,3260] (multiple)
iscsiadm: got read error (0/0), daemon died?
iscsiadm: Could not login to [iface: default, target:

iscsiadm: initiator reported error (18 - could not communicate to iscsid)

Maybe the lines with sysfs_attr_get_value are indicative of something that's
needed from /sys still?
These exact same discovery and login commands work fine running from a libvirt
vm connecting to the same target.
On my container host, i do have the correct iscsi kernel modules, and I also
see these in the container:
on the host:
[root@teletran-1 docker]# lsmod | grep iscsi
iscsi_tcp 18333 0
libiscsi_tcp 24176 1 iscsi_tcp
libiscsi 54750 2 libiscsi_tcp,iscsi_tcp
scsi_transport_iscsi 97405 4 iscsi_tcp,libiscsi
on the container:
[root@bcf697cb8673 ~]# lsmod | grep iscsi
iscsi_tcp 18333 0
libiscsi_tcp 24176 1 iscsi_tcp
libiscsi 54750 2 libiscsi_tcp,iscsi_tcp
scsi_transport_iscsi 97405 4 iscsi_tcp,libiscsi
i'll attach an strace of the iscsid process that's exiting, if that helps.
i can also attach an strace of an iscsid process that shows it working from a
libvirt VM, if you think that would be helpful to compare.
--- Additional comment from James Slagle on 2014-05-29 09:37:12 EDT ---
strace of iscsid generated with:
strace -f -o iscsid.strace iscsid -d 12 -f
the iscsid process exits when you try to login to an iscsi target from the
container.
--- Additional comment from James Slagle on 2014-05-29 10:08:33 EDT ---
note that the output i'm now seeing seems to match very closely what was
reported in https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1226855 when
this same thing was tried with lxc-tools instead of Docker.
--- Additional comment from Daniel Walsh on 2014-05-29 15:32:31 EDT ---
So this looks to be more specific to iscsid and namespacing then to docker. I
think you should open the bug with them and see if they can help.
--- Additional comment from Chris Leech on 2014-06-04 19:44:37 EDT ---
It looks like the iSCSI netlink control interface isn't namespace aware, and
the kernel side of the iSCSI initiator rejects messages that don't come from
the default network namespace. I suppose it might make sense to track active
sessions per netns.

FYI I was playing with running iscsid in superprivileged container:
https://github.com/rvykydal/dockerfile-iscsid/tree/master/rhel7
--- Additional comment from Chris Leech on 2015-04-23 13:30:38 EDT ---
I've spent some more time looking at running iscsid in a network namespace
container, and there are a number of kernel issues that need to be worked out.
The kernel side of the iSCSI netlink family only listens in the initial network
namespace (just like some other storage related netlink families). It's easy
enough to add per-namespace kernel sockets, a bit more work to associate
network namespaces to iSCSI objects in order to route async event notifications
to the right place.
iSCSI makes heavy use of sysfs as well, and many of the iSCSI sysfs devices
will need network namespace tags for filtered views of sysfs. I think that
makes sense for iscsi_host, iscsi_session, and iscsi_connection. Certainly not
for iscsi_transport. Possibly for iscsi_endpoint and iscsi_iface.
Without growing some way to assign an iscsi_host to a net namespace like is
done for network devices, this will probably work for dynamically generated
hosts (iscsi_tcp) but not for offload hardware.
I can imagine use cases where it might be nice to have multiple iscsid
instances in their own containers managing their own set of iSCSI sessions.
I've got some work started, but it's not ready for review and testing just yet.
Without that, I don't see how we can get to multiple working iscsid processes
or even a single iscsid running without --net=host
--- Additional comment from Fedora End Of Life on 2015-05-29 07:55:11 EDT ---
This message is a reminder that Fedora 20 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 20. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
of '20'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 20 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

Any progress on this patch?
--- Additional comment from Fedora End Of Life on 2016-07-19 07:32:46 EDT ---
Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.
Thank you for reporting this bug and we are sorry it could not be fixed.
--- Additional comment from Daniel Walsh on 2016-07-19 10:18:03 EDT ---
Is this something we should continue to care about?
--- Additional comment from Jan Kurik on 2016-07-26 00:08:27 EDT ---
This bug appears to have been reported against 'rawhide' during the Fedora 25
development cycle.
Changing version to '25'.
