As described in the BLS, we should place binaries into the XBOOTLDR
directory if it is available, otherwise into the ESP. Thus, we might
need to put binaries into /boot or into /efi depending on the existence
of the XBOOTLDR partition.
With this change, we introduce a new PathRelativeTo= config option that
makes this functionality possible
Let's check if we keep the old records after multiple systemd-pstore
invocations (i.e. simulate a scenario where we get multiple crashes and
multiple machine reboots).
We check for homed stuff in the test itself, but this is way too late,
since we already started a unit that Requires=systemd-homed.service
(testsuite-46.service). For now this doesn't matter, but with #27852
the offending transaction is dropped from the job queue, making the test
fail.
Spotted in #27852 in Ubuntu CI.
Fixes a regression caused by ab3aed4a03.
I thought the commit does not cause any severe regression. However,
drivers for network interfaces may be loaded later. So, we should wait
if no network interface is found.
Fixes#27822.
Containers generally don't have permission to mknod() which is
required by test-udev so let's skip the test as well if we detect
we're running in a container.
Currently, ExcludeFiles= supports excluding directories on the host
from being copied. Let's extend this to also support preventing files
from being copied into specific directories in the partition by adding
a new option ExcludeFilesTarget=. An example where this is useful is
when setting up btrfs subvolumes in the top level that are intended to
be mounted into specific locations, so /usr would be stored in @usr,
/home in @home, .... To accomplish this, we need to copy /usr to @usr
and prevent any files from being copied into /usr in the partition,
which with this commit, we'd be able to do as follows:
```
[Partition]
CopyFiles=/usr:@usr
ExcludeFilesTarget=/usr
```
The setting IPv6AcceptRA= is defaults to yes, hence, even if a .network
file for an interface has static IP address configuration, it may takes
few seconds for the interface being configured state, as NDisc for the
interface needs to be finished. That makes wait-online.service
needlessly slow. Typically, such delay is not necessary for statically
configured networks.
Let's make the required condition slightly relaxed; if a .network file
has static IP address configurations, then let's make the matching
interface enter the 'configured' state soon after the static addresses
configured on the interface.
Note, this does not change the default for IPv6AcceptRA=, hence, NDisc
still runs on interfaces by default. So, addresses, routes, DNS servers,
and so on based on RA will be assigned on interfaces later.
Strictly speaking, this breaks backward compatibility, but the previous
behavior is not clearly documented. If a user requested both static
IPv4 address and IPv6 SLAAC address configured before an interface being
entered to the 'configured' state, then '--ipv6' for wait-online can be
used. So, the behavior change should not cause severe regression.
Closes#27779.
There is really no reason to go out of our way to create the config files as
the unprivileged user. And in the logs, the runas calls are quite verbose,
distracting from the interesting stuff. Also add .defs/.imgs/.root to the
temporary paths to make them easier to distinguish in the logs.
KERNEL_APPEND="systemd.unit=multi-user.target" is not very useful, because the
machine will still shut down as soon as the tests succeeds or fails. But
INTERACTIVE_DEBUG=1 works great, so let's simplify the instructions and
recommend that.
The gc_unit_queue is dispatched before the cgroup_empty_queue. Because
of this, when we enter in on_cgroup_empty_event, the unit in
cgroup_empty_queue may already have been freed and we don't clean up the
corresponding cgroup. With this change, we prevent the unit from being
garbage collected if it is in the cgroup_empty_queue.
When there is no matching entry stored in journal, then initial call of
`sd_journal_previous()` following `sd_journal_seek_tail()` returns
zero, and does not move the read pointer.
In the main loop, on every journal event, we call `sd_journal_next()`,
even though the current location is tail, and it takes no effect.
In such a case, we need to call `sd_journal_previous()` instead of
`sd_journal_next()`.
Temporarily revert the test case for #27167, as the additional
daemon-reexecs exacerbate #27287, making CIs fail quite often.
As the #27167 is also covered by TEST-01-BASIC itself, since we do
daemon-reexec there anyway, we shouldn't lose any coverage, but it
should make CIs more stable until #27287 is figured out.
Resolves (or more like works around): #27807
This reverts commit d689f70a2c.
Previously, dependency chain of JoinsNamespaceOf= did not work, e.g.
- a.service has JoinsNamespaceOf=b.service
- b.service has JoinsNamespaceOf=c.service
if, first c.service, next a.service, finally b.service is started,
then a.service is not joined to the namespace of c.service. And, as
mentioned in the document, the namespace used by b.service is not
deterministic.
This makes when searching exsiting namespace to be joined, all units in
the transitive dependency of JoinsNamespaceOf= are checked.
Previously, even if a.service has JoinsNamespaceOf=b.service, the
inverse direction of reference was not introduced.
Hence, a.service is started earlier than b.service, the namespace will
not shared with b.service.
Also, even if a.service had the reference to b.service, b.service did not.
If b.service is freed earlier, then unit_clear_dependencies() does not clear
the reference from a to b, and will cause use-after-free on unit_free() for
a.service.
Let's make JoinsNamespaceOf=b.service in a.service implies the inverse
dependency, i.e. JoinsNamespaceOf=a.service for b.service. Then, we can safely
free b.service.
