Bug Description

[Impact]

When using iSCSI storage underneath cloud applications such as OpenStack or Kubernetes, the automatic bus scan on login causes problems, because it results in SCSI disks being registered in the kernel that will never get cleaned up, and when those disks are eventually deleted off the server, I/O errors begin to accumulate, eventually slowing down the whole SCSI subsystem, spamming the kernel log, and causing timeouts at higher levels such that users are forced to reboot the node to get back to a usable state.

[Test Case]

################

# To demonstrate this problem, I create a VM running Ubuntu 20.04.0

# Install both iSCSI initiator and target on this host
sudo apt-get -y install open-iscsi targetcli-fb

# Start the services
sudo systemctl start iscsid.service targetclid.service

# Create a randomly generated target IQN
TARGET_IQN=$(iscsi-iname)

# Get the initator IQN
INITIATOR_IQN=$(sudo awk -F = '/InitiatorName=/ {print $2}' /etc/iscsi/initiatorname.iscsi)

# Set up an iSCSI target and target portal, and grant access to ourselves
sudo targetcli /iscsi create $TARGET_IQN
sudo targetcli /iscsi/$TARGET_IQN/tpg1/acls create $INITIATOR_IQN

# Create two 1GiB LUNs backed by files, and expose them through the target portal
sudo targetcli /backstores/fileio create lun1 /lun1 1G
sudo targetcli /iscsi/$TARGET_IQN/tpg1/luns create /backstores/fileio/lun1 1
sudo targetcli /backstores/fileio create lun2 /lun2 1G
sudo targetcli /iscsi/$TARGET_IQN/tpg1/luns create /backstores/fileio/lun2 2

# Truncate the kernel log so we can see messages after this point only
sudo dmesg -C

# Register the local iSCSI target with out initiator, and login
sudo iscsiadm -m node -p 127.0.0.1 -T $TARGET_IQN -o new
sudo iscsiadm -m node -p 127.0.0.1 -T $TARGET_IQN --login

# Get the list of disks from the iSCSI session, and stash it in an array
eval "DISKS=\$(sudo iscsiadm -m session -P3 | awk '/Attached scsi disk/ {print \$4}')"

# Print the list
echo $DISKS

# Note that there are two disks found already (the two LUNs we created
# above) despite the fact that we only just logged in.

# Now delete a LUN from the target
sudo targetcli /iscsi/$TARGET_IQN/tpg1/luns delete lun2
sudo targetcli /backstores/fileio delete lun2

# Attempt to read each of the disks
for DISK in $DISKS ; do sudo blkid /dev/$DISK || true ; done

# Look at the kernel log
dmesg

# Notice I/O errors related to the disk that the kernel remembers

################

# Now to demostrate how this problem is fixed, I create a new Ubuntu 20.04.0 VM

# Add PPA with modified version of open-iscsi
sudo add-apt-repository -y ppa:bswartz/open-iscsi
sudo apt-get update

# Install both iSCSI initiator and target on this host
sudo apt-get -y install open-iscsi targetcli-fb

sudo systemctl restart iscsid.service

# Create a randomly generated target IQN
TARGET_IQN=$(iscsi-iname)

# Get the initator IQN
INITIATOR_IQN=$(sudo awk -F = '/InitiatorName=/ {print $2}' /etc/iscsi/initiatorname.iscsi)

# Set up an iSCSI target and target portal, and grant access to ourselves

# Get the list of disks from the iSCSI session, and stash it in an array
eval "DISKS=\$(sudo iscsiadm -m session -P3 | awk '/Attached scsi disk/ {print \$4}')"

# Print the list
echo $DISKS

# Note that the list is empty!

# Get the iSCSI host
SCSI_HOST=$(ls /sys/class/iscsi_host)

# Specifically scan the one disk we want
sudo sh -c "echo '0 0 1' > /sys/class/scsi_host/$SCSI_HOST/scan"

# Get the list of disks from the iSCSI session, and stash it in an array
eval "DISKS=\$(sudo iscsiadm -m session -P3 | awk '/Attached scsi disk/ {print \$4}')"

# Print the list
echo $DISKS

# This time notice there's exactly one disk

# Now delete the other LUN from the target
sudo targetcli /iscsi/$TARGET_IQN/tpg1/luns delete lun2
sudo targetcli /backstores/fileio delete lun2

# Attempt to read each of the disks
for DISK in $DISKS ; do sudo blkid /dev/$DISK || true ; done

# Look at the kernel log
dmesg

# No errors in the log

[Regression Potential]

These changes have been proven safe by 3 years of soak time in the RedHat ecosystem, so I don't see much risk to taking them into Ubuntu. They apply cleanly to the most recent versions of focal, bionic, and xenial.

The change introduces a new config option in iscsid.conf but the default is to do exactly what it used to do. Only users who explicitly change this option will get altered behavior, and the behavior with the option set is
superior for the above mentioned cloud use cases.

[Other Info]

RedHat discovered this problem more than 3 years ago and fixed it upstream.

https://bugzilla.redhat.com/show_bug.cgi?id=1422941

I had hoped that Debian would eventually pick up the version in which it was fixed, but another LTS has gone by without picking up the newer upstream version, and this is a critical problem, so I propose backporting the fixes.

The 2 patches that need porting are:
https://github.com/open-iscsi/open-iscsi/pull/40
https://github.com/open-iscsi/open-iscsi/pull/49

Looks like we've been very cautious with open-iscsi package:

I'm marking this for a merge for groovy and blocking -proposed for groovy. Since this is behavior change I'll have to discuss this as being a SRU with a broader audience (specially our openstack team).. but marking as affecting all previous supported releases as well.

Thanks for the bug report!

Rafael David Tinoco (rafaeldtinoco) wrote on 2020-05-11:

Alright, this *new feature* (which is actually fixing an unwanted behavior) has the following section added to iscsid.conf:

# To prevent doing automatic scans that would add unwanted luns to the system
# we can disable them and have sessions only do manually requested scans.
# Automatic scans are performed on startup, on login, and on AEN/AER reception
# on devices supporting it. For HW drivers all sessions will use the value
# defined in the configuration file. This configuration option is independent
# of scsi_mod scan parameter. (The default behavior is auto):
node.session.scan = auto

And this makes it to have the exact same behavior as before this fix, so this makes it suitable for SRU. I'm doing the merge requests and will link to this bug. I'm doing the same change for groovy BUT it will be a new merge with upstream.

Sure Ben,

I have also suggested Debian maintainers:

https://salsa.debian.org/linux-blocks-team/open-iscsi/-/merge_requests/2
https://salsa.debian.org/linux-blocks-team/open-iscsi/-/merge_requests/3

to sync with upstream. Will give them a while to provide answers so I can merge/sync with Debian. If, by any chance, they don't sync with upstream, I'll move Ubuntu forward to 2.1.1 and let them to catch up eventually.

Cheers

Okay that sounds like a great option. I was planning to talk to the Debian maintainers eventually but Ubuntu is more important to me. If I can get this issue fixed in both distros that's so much the better.

Well, yep, Ubuntu tries not to add deltas to Debian unless they're *really* needed. This makes Debian and Ubuntu healthy. Upstream has merged my request to experimental, I'll sync it back to Ubuntu as soon as our importers have recognized the new version.

Cheers!

Is the version update something that can be backported to Bionic and even Xenial? A number of users run well behind the latest LTS.

Rafael David Tinoco (rafaeldtinoco) wrote on 2020-05-13:

Not the entire version bump, no, per SRU guidelines (https://wiki.ubuntu.com/StableReleaseUpdates). The auto_scan change, yes.. I'm backporting it to bionic. Anything besides that would have to be a backport, maintained *by someone* in -backports (https://help.ubuntu.com/community/UbuntuBackports).

Yes, I'm working with upstream:

https://salsa.debian.org/linux-blocks-team/open-iscsi/-/merge_requests/4/commits

I have basically reviewed all previous open-iscsi packages.

Let's see further discussions on how they see that.

For the SRUs (3 of them, in the merge requests). They were accepted by a peer of mine, so I basically to test if behavior is kept as default for all 3 of them and then I'll upload the fixes. I'll basically run your test case on all 3 packages and upload the binaries after I'm done. Will finish this soon, gave a better attention to upstream so we could bump the version there.

Rafael David Tinoco (rafaeldtinoco) wrote on 2020-05-19:

Okay so the 3 SRUs are uploaded waiting to be approved.

I have also proposed a merge request in salsa:

https://salsa.debian.org/linux-blocks-team/open-iscsi/-/merge_requests/4

refactoring a bit the package itself and solving the openssl linking issue the upstream maintainer has observed. Haven't yet decided if Ubuntu will keep the CHAP auth algs support from openssl or not (pending ubuntu-devel@ mailing list discussion thread).

For now thats it, waiting on upstream and SRU.

Just tested SRU and it works fine. By setting:

OR by making sure to have:

I haven't backported it to Xenial, will flag it as won't fix. Xenial is too "mature" to change right now, all cloud archives are bionic oriented (or should be)... will flag it as won't fix so its more clear.
