Upgrading the nfs-common debian package will not restart its services.
Specifically, the package tries to restart "nfs-utils.service", which is a "fake" service meant to coordinate all the other daemons that make up a modern NFS server. This service, however, as it is, cannot be enabled:
$ sudo systemctl enable nfs-utils.service
The unit files have no installation config (WantedBy, RequiredBy, Also, Alias
settings in the [Install] section, and DefaultInstance for template units).
This means they are not meant to be enabled using systemctl.
Possible reasons for having this kind of units are:
1) A unit may be statically enabled by being symlinked from another unit's
.wants/ or .requires/ directory.
2) A unit's purpose may be to act as a helper for some other unit which has
a requirement dependency on it.
3) A unit may be started when needed via activation (socket, path, timer,
D-Bus, udev, scripted systemctl call, ...).
4) In case of template units, the unit is meant to be enabled with some
instance name specified
Granted, d/rules of the nfs-utils package doesn't even try:
dh_systemd_enable -p nfs-common nfs-client.target
dh_systemd_enable -p nfs-kernel-server nfs-server.service
dh_installinit -pnfs-common -R
dh_systemd_start -p nfs-common --restart-after-upgrade nfs-utils.service
dh_systemd_start -p nfs-kernel-server --restart-after-upgrade nfs-server.service
We can see it tries to start and restart it, but that won't work on disabled or non-started services: deb-systemd-invoke won't do it:
# If the job is disabled and is not currently running, the job is not started or restarted.
# However, if the job is disabled but has been forced into the running state, we *do* stop
# and restart it since this is expected behaviour for the admin who forced the start.
# We don't autostart static units either.
The above can be seen while attempting a fresh install (or even upgrade) of nfs-common:
(...)
Setting up nfs-common (1:1.3.4-2.5ubuntu6) ...
Creating config file /etc/idmapd.conf with new version
Adding system user `statd' (UID 113) ...
Adding new user `statd' (UID 113) with group `nogroup' ...
Not creating home directory `/var/lib/nfs'.

This was found while testing the fix for bug #1927745. In that bug, the affected service is rpc.gssd and it's critical that it be restarted, but it's not happening. It will only be restarted if nfs-utils.service is already "started".
I'm marking this bug as "high" because it prevents valid fixes from being deployed after just upgrading a package. |
[Impact]

the problem.

[Where problems could occur]
* Think about what the upload changes in the software. Imagine the change is
wrong or breaks something else: how would this show up?
* It is assumed that any SRU candidate patch is well-tested before
upload and has a low overall risk of regression, but it's important

[Impact]
In order to get the fixes provided by a package update, the affected services shipped in it need to be restarted. When that restart does not happen, the system remains running the old binaries with the bug(s).
This bug was found while testing the fix for #1927745, which affected rpc.gssd, one of the services shipped in nfs-common. Without the restart, systems that installed the update are still affected by the bug.
[Test Plan]
To make the test simple, we are not going to mount an NFSv4 share using kerberos. We are just going to have a minimal configuration that gets rpc.gssd running to demonstrate the before and after of this bug.
# create a VM for the affected ubuntu release under test, login and run:
sudo touch /etc/krb5.keytab
sudo chmod 0600 /etc/krb5.keytab
# install nfs-common
sudo apt install nfs-common -y
# note message about nfs-utils.service being disabled/static:
nfs-utils.service is a disabled or a static unit, not starting it.
# Manually start rpc-gssd. It will start, but since we have an empty
# krb5.keytab file, it won't work. That's ok, we are not actually going to
# mount nfsv4
systemctl start rpc-gssd.service
# Check it's running, and make note of its pid:
pidof rpc.gssd
2994
# reinstall nfs-common
sudo apt install --reinstall nfs-common
# note rpc-gssd wasn't restarted
pidof rpc.gssd
2994
# install the fixed nfs-common package:
sudo apt install nfs-commont
# this time, rpc.gssd is restarted

[Impact]
In order to get the fixes provided by a package update, the affected services shipped in it need to be restarted. When that restart does not happen, the system remains running the old binaries with the bug(s).
This bug was found while testing the fix for #1927745, which affected rpc.gssd, one of the services shipped in nfs-common. Without the restart, systems that installed the update are still affected by the bug.
[Test Plan]
To make the test simple, we are not going to mount an NFSv4 share using kerberos. We are just going to have a minimal configuration that gets rpc.gssd running to demonstrate the before and after of this bug.
# create a VM for the affected ubuntu release under test, login and run:
sudo touch /etc/krb5.keytab
sudo chmod 0600 /etc/krb5.keytab
# install nfs-common
sudo apt install nfs-common -y
# note message about nfs-utils.service being disabled/static:
nfs-utils.service is a disabled or a static unit, not starting it.
# Manually start rpc-gssd. It will start, but since we have an empty
# krb5.keytab file, it won't work. That's ok, we are not actually going to
# mount nfsv4

Also known as "I'm doing an unconditional start in postinst, what could go wrong":
- start services that were not started with the previous package on first install
- systemd behavior change or bug and suddenly PartOf units also react to "start", instead of just "restart" and "stop" as documented
- starting services that are not configured, and start fails, breaking postinst (but we have the proverbial || true to avoid that)
[Other Info]
This fix is a bit awkward, but I think it's in line with the SRU spirit of doing the least unpredictable change, and one that is simple and can be better understood.
See the linked MP for an explanation of this fix, why it works, and other tests I did:
https://code.launchpad.net/~ahasenack/ubuntu/+source/nfs-utils/+git/nfs-utils/+merge/403288
[Original Description]
Upgrading the nfs-common debian package will not restart its services.
Specifically, the package tries to restart "nfs-utils.service", which is a "fake" service meant to coordinate all the other daemons that make up a modern NFS server. This service, however, as it is, cannot be enabled:
$ sudo systemctl enable nfs-utils.service
The unit files have no installation config (WantedBy, RequiredBy, Also, Alias
settings in the [Install] section, and DefaultInstance for template units).
This means they are not meant to be enabled using systemctl.
Possible reasons for having this kind of units are:
1) A unit may be statically enabled by being symlinked from another unit's
.wants/ or .requires/ directory.
2) A unit's purpose may be to act as a helper for some other unit which has
a requirement dependency on it.
3) A unit may be started when needed via activation (socket, path, timer,
D-Bus, udev, scripted systemctl call, ...).
4) In case of template units, the unit is meant to be enabled with some
instance name specified
Granted, d/rules of the nfs-utils package doesn't even try:
dh_systemd_enable -p nfs-common nfs-client.target
dh_systemd_enable -p nfs-kernel-server nfs-server.service
dh_installinit -pnfs-common -R
dh_systemd_start -p nfs-common --restart-after-upgrade nfs-utils.service
dh_systemd_start -p nfs-kernel-server --restart-after-upgrade nfs-server.service
We can see it tries to start and restart it, but that won't work on disabled or non-started services: deb-systemd-invoke won't do it:
# If the job is disabled and is not currently running, the job is not started or restarted.
# However, if the job is disabled but has been forced into the running state, we *do* stop
# and restart it since this is expected behaviour for the admin who forced the start.
# We don't autostart static units either.
The above can be seen while attempting a fresh install (or even upgrade) of nfs-common:
(...)
Setting up nfs-common (1:1.3.4-2.5ubuntu6) ...
Creating config file /etc/idmapd.conf with new version
Adding system user `statd' (UID 113) ...
Adding new user `statd' (UID 113) with group `nogroup' ...

This was found while testing the fix for bug #1927745. In that bug, the affected service is rpc.gssd and it's critical that it be restarted, but it's not happening. It will only be restarted if nfs-utils.service is already "started".
I'm marking this bug as "high" because it prevents valid fixes from being deployed after just upgrading a package. |

[Impact]
In order to get the fixes provided by a package update, the affected services shipped in it need to be restarted. When that restart does not happen, the system remains running the old binaries with the bug(s).
This bug was found while testing the fix for #1927745, which affected rpc.gssd, one of the services shipped in nfs-common. Without the restart, systems that installed the update are still affected by the bug.
[Test Plan]
To make the test simple, we are not going to mount an NFSv4 share using kerberos. We are just going to have a minimal configuration that gets rpc.gssd running to demonstrate the before and after of this bug.
For a more thorough testing, which includes actually mounting an NFSv4 export with kerberos, follow the test instructions of bug #1927745, and you will see that the manual restart included because of this bug here, after the package is updated, is no longer needed.
TEST (A)
# create a VM for the affected ubuntu release under test, login and run:
sudo touch /etc/krb5.keytab
sudo chmod 0600 /etc/krb5.keytab
# install nfs-common
sudo apt install nfs-common -y
# note message about nfs-utils.service being disabled/static:
nfs-utils.service is a disabled or a static unit, not starting it.
# Manually start rpc-gssd. It will start, but since we have an empty
# krb5.keytab file, it won't work. That's ok, we are not actually going to
# mount nfsv4
systemctl start rpc-gssd.service
# Check it's running, and make note of its pid:
pidof rpc.gssd
2994
# reinstall nfs-common
sudo apt install --reinstall nfs-common
# note rpc-gssd wasn't restarted
pidof rpc.gssd
2994
# install the fixed nfs-common package. Notice the message about starting a disabled or static unit no longer appears:
sudo apt install nfs-common
# this time, rpc.gssd is restarted
pidof rpc.gssd
5000
TEST (B)
This test is to confirm no new services are started after the fixed package is installed for the first time.
# create a VM for the affected ubuntu release under test, login and run:
sudo touch /etc/krb5.keytab
sudo chmod 0600 /etc/krb5.keytab
# install nfs-common that has the bug
sudo apt install nfs-common -y
# take a snapshot of running processes
pstree > pstree.old
# purge the nfs-common package
sudo apt purge nfs-common -y
# install the new nfs-common package
sudo apt purge nfs-common -y
# take a new pstree snapshot and compare with the old one
pstree > pstree.new
diff -u pstree.old pstree.new
Should be no difference.
[Where problems could occur]
Also known as "I'm doing an unconditional start in postinst, what could go wrong":
- start services that were not started with the previous package on first install
- systemd behavior change or bug and suddenly PartOf units also react to "start", instead of just "restart" and "stop" as documented
- starting services that are not configured, and start fails, breaking postinst (but we have the proverbial || true to avoid that)
[Other Info]
This fix is a bit awkward, but I think it's in line with the SRU spirit of doing the least unpredictable change, and one that is simple and can be better understood.
See the linked MP for an explanation of this fix, why it works, and other tests I did:
https://code.launchpad.net/~ahasenack/ubuntu/+source/nfs-utils/+git/nfs-utils/+merge/403288
[Original Description]
Upgrading the nfs-common debian package will not restart its services.
Specifically, the package tries to restart "nfs-utils.service", which is a "fake" service meant to coordinate all the other daemons that make up a modern NFS server. This service, however, as it is, cannot be enabled:
$ sudo systemctl enable nfs-utils.service
The unit files have no installation config (WantedBy, RequiredBy, Also, Alias
settings in the [Install] section, and DefaultInstance for template units).
This means they are not meant to be enabled using systemctl.
Possible reasons for having this kind of units are:
1) A unit may be statically enabled by being symlinked from another unit's
.wants/ or .requires/ directory.
2) A unit's purpose may be to act as a helper for some other unit which has
a requirement dependency on it.
3) A unit may be started when needed via activation (socket, path, timer,
D-Bus, udev, scripted systemctl call, ...).
4) In case of template units, the unit is meant to be enabled with some
instance name specified
Granted, d/rules of the nfs-utils package doesn't even try:
dh_systemd_enable -p nfs-common nfs-client.target
dh_systemd_enable -p nfs-kernel-server nfs-server.service
dh_installinit -pnfs-common -R
dh_systemd_start -p nfs-common --restart-after-upgrade nfs-utils.service
dh_systemd_start -p nfs-kernel-server --restart-after-upgrade nfs-server.service
We can see it tries to start and restart it, but that won't work on disabled or non-started services: deb-systemd-invoke won't do it:
# If the job is disabled and is not currently running, the job is not started or restarted.
# However, if the job is disabled but has been forced into the running state, we *do* stop
# and restart it since this is expected behaviour for the admin who forced the start.
# We don't autostart static units either.
The above can be seen while attempting a fresh install (or even upgrade) of nfs-common:
(...)
Setting up nfs-common (1:1.3.4-2.5ubuntu6) ...
Creating config file /etc/idmapd.conf with new version
Adding system user `statd' (UID 113) ...
Adding new user `statd' (UID 113) with group `nogroup' ...
Not creating home directory `/var/lib/nfs'.
Created symlink /etc/systemd/system/multi-user.target.wants/nfs-client.target → /lib/systemd/system/nfs-client.target.
Created symlink /etc/systemd/system/remote-fs.target.wants/nfs-client.target → /lib/systemd/system/nfs-client.target.

We can see it tries to start and restart it, but that won't work on disabled or non-started services: deb-systemd-invoke won't do it:
# If the job is disabled and is not currently running, the job is not started or restarted.
# However, if the job is disabled but has been forced into the running state, we *do* stop
# and restart it since this is expected behaviour for the admin who forced the start.
# We don't autostart static units either.
The above can be seen while attempting a fresh install (or even upgrade) of nfs-common:
(...)
Setting up nfs-common (1:1.3.4-2.5ubuntu6) ...
Creating config file /etc/idmapd.conf with new version
Adding system user `statd' (UID 113) ...
Adding new user `statd' (UID 113) with group `nogroup' ...
Not creating home directory `/var/lib/nfs'.
Created symlink /etc/systemd/system/multi-user.target.wants/nfs-client.target → /lib/systemd/system/nfs-client.target.
Created symlink /etc/systemd/system/remote-fs.target.wants/nfs-client.target → /lib/systemd/system/nfs-client.target.
nfs-utils.service is a disabled or a static unit, not starting it.
^^^^^^^^^^^^^^^^^
$ systemctl status nfs-utils.service
● nfs-utils.service - NFS server and client services
Loaded: loaded (/lib/systemd/system/nfs-utils.service; static)
Active: inactive (dead)
This was found while testing the fix for bug #1927745. In that bug, the affected service is rpc.gssd and it's critical that it be restarted, but it's not happening. It will only be restarted if nfs-utils.service is already "started".
I'm marking this bug as "high" because it prevents valid fixes from being deployed after just upgrading a package. |
