It turns out the "supporting services" were run in _all_ tests if
TEST-01-BASIC was run as the first test (which is usually the case),
since with the original condition in test_create_image() we would skip
the masking and then propagate the change to the default image used by
other tests. This has been causing multiple bogus test timeouts
(especially when the hwdb was being rebuilt in tests with short
timeouts, like TEST-52-HONORFIRSTSHUTDOWN).
Let's "fix" this by making the call to mask_supporting_services()
uncoditional and override the test_create_image() function in
TEST-01-BASIC to avoid the masking in this single case.
When checking the unit state after `systemctl freeze|thaw` we can be
"too fast" and get the intermediate state (freezing/thawing) which we're
not interested in. Let's wait a bit and try to get the state again in
such cases to avoid unnecessary flakiness.
```
[ 29.390203] testsuite-38.sh[218]: + state=thawing
[ 29.390203] testsuite-38.sh[218]: + '[' thawing = running ']'
[ 29.390203] testsuite-38.sh[218]: + echo 'error: unexpected freezer state, expected: running, actual: thawing'
[ 29.390203] testsuite-38.sh[218]: error: unexpected freezer state, expected: running, actual: thawing
[ 29.390203] testsuite-38.sh[218]: + exit 1
```
test-loop-block needs to run in qemu, so we are currently not
testing it in the CI. Run it by itself in a separate job from
TEST-02-UNITTESTS to avoid slowing that suite down.
Fixes https://github.com/systemd/systemd/issues/19966
Disable it in the bionic-* CI for now, as it's affected by
the same uevent ordering issue as TEST-50-DISSECT which makes
it flaky.
In many CI runs I noticed a race where we check the "active" state a bit
too early where the unit is still in the "inactive" state, causing the
`is-failed` check to fail. Mitigate this by waiting even if the unit is
in the inactive state and introduce a "safe net" which checks whether
the unit is not restarting indefinitely or more than it should (as
described in the original issue #3166).
Example:
```

The three-argument match() is a GNU AWK extension, thus breaking the
compatibility with mawk (used on Ubuntu/Debian, for example). Let's
replace it with a (hopefully) more portable sed expression to drop the
inadvertently introduced gawk dependency.

The currently hardcoded value works with the default configuration, but
breaks when QEMU_MEM != 512M (in sanitizer runs, for example).
```
# QEMU_MEM=1G make -C test/TEST-36-NUMAPOLICY/ run
make: Entering directory '/home/fsumsal/repos/@systemd/systemd/test/TEST-36-NUMAPOLICY'
TEST-36-NUMAPOLICY RUN: test NUMAPolicy= and NUMAMask= options
+ /bin/qemu-kvm -smp 8 -net none -m 1G -nographic -kernel /boot/vmlinuz-5.12.5-300.fc34.x86_64 -drive format=raw'
qemu-kvm: total memory for NUMA nodes (0x20000000) should equal RAM size (0x40000000)
E: QEMU failed with exit code 1
```
It's hard to trigger the failure to exit the rate limit state in
isolation as it needs multiple event sources in order to show that it
gets stuck in the queue. Hence why this is an extended test.
Previously, IPv6LinkLocalAddressGenerationMode= is not set, then we
define the address generation mode based on the result of reading
stable_secret sysctl value. This makes the mode is determined by whether
a secret address is specified in the new setting.
Closes#19622.
For "systemd-tmpfiles --cleanup", when the "Age" parameter
is specified, the criteria for deletion is determined from
the path's last modification timestamp ("mtime"), its last
access timestamp ("atime") and its last status change
timestamp ("ctime").
For instance, if one of those paths to be cleaned up are
opened, it results in the modification of "atime", which
results file system entry to not be removed because the
default aging algorithm would skip the entry.
Add an optional "age-by" argument by extending the "Age"
parameter to restrict the clean-up for a particular type
of file timestamp, which can be specified in "tmpfiles.d"
as follows:
[age-by:]cleanup-age, where age-by is "[abcmACBM]+"
For example:
d /foo/bar - - - abM:1m -
Would clean-up any files that were not accessed and created,
or directories that were not modified less than a minute ago
in "/foo/bar".
Fixes: #17002
Add the '=' action modifier that instructs tmpfiles.d to check the file
type of a path and remove objects that do not match before trying to
open or create the path.

When fuzzing, the following happens:
- we parse 'data' and produce an argv array,
- one of the items in argv is assigned to arg_host,
- the argv array is subsequently freed by strv_freep(), and arg_host has a dangling symlink.
In normal use, argv is static, so arg_host can never become a dangling pointer.
In fuzz-systemctl-parse-argv, if we repeatedly parse the same array, we
have some dangling pointers while we're in the middle of parsing. If we parse
the same array a second time, at the end all the dangling pointers will have been
replaced again. But for a short time, if parsing one of the arguments uses another
argument, we would use a dangling pointer.
Such a case occurs when we have --host=… --boot-loader-entry=help. The latter calls
acquire_bus() which uses arg_host.
I'm not particularly happy with making the code more complicated just for
fuzzing, but I think it's better to resolve this, even if the issue cannot
occur in normal invocations, than to deal with fuzzer reports.
Should fix https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=31714.
without waiting for online, there is a race condition between systemd-networkd
actually setting the new values and the test checking those values
This also sets the link down before restarting systemd-networkd, to avoid
the wait for online being a no-op
This is like a really strong version of Wants=, that keeps starting the
specified unit if it is ever found inactive.
This is an alternative to Restart= inside a unit, acknowledging the fact
that whether to keep restarting the unit is sometimes not a property of
the unit itself but the state of the system.
This implements a part of what #4263 requests. i.e. there's no
distinction between "always" and "opportunistic". We just dumbly
implement "always" and become active whenever we see no job queued for
an inactive unit that is supposed to be upheld.
This is similar to OnFailure= but is activated whenever a unit returns
into inactive state successfully.
I was always afraid of adding this, since it effectively allows building
loops and makes our engine Turing complete, but it pretty much already
was it was just hidden.
Given that we have per-unit ratelimits as well as an event loop global
ratelimit I feel safe to add this finally, given it actually is useful.
Fixes: #13386
This takes inspiration from PropagatesReloadTo=, but propagates
stop jobs instead of restart jobs.
This is defined based on exactly two atoms: UNIT_ATOM_PROPAGATE_STOP +
UNIT_ATOM_RETROACTIVE_STOP_ON_STOP. The former ensures that when the
unit the dependency is originating from is stopped based on user
request, we'll propagate the stop job to the target unit, too. In
addition, when the originating unit suddenly stops from external causes
the stopping is propagated too. Note that this does *not* include the
UNIT_ATOM_CANNOT_BE_ACTIVE_WITHOUT atom (which is used by BoundBy=),
i.e. this dependency is purely about propagating "edges" and not
"levels", i.e. it's about propagating specific events, instead of
continious states.
This is supposed to be useful for dependencies between .mount units and
their backing .device units. So far we either placed a BindsTo= or
Requires= dependency between them. The former gave a very clear binding
of the to units together, however was problematic if users establish
mounnts manually with different block device sources than our
configuration defines, as we there might come to the conclusion that the
backing device was absent and thus we need to umount again what the user
mounted. By combining Requires= with the new StopPropagatedFrom= (i.e.
the inverse PropagateStopTo=) we can get behaviour that matches BindsTo=
in every single atom but one: UNIT_ATOM_CANNOT_BE_ACTIVE_WITHOUT is
absent, and hence the level-triggered logic doesn't apply.

Add quotes around use of $env{MODALIAS} in rules.d/80-drivers.rules. The
modalias can contain whitespace, for example when it is dynamically generated
using device or vendor IDs.
There are nothing we can configure in udevd for loopback interfaces;
no ethertool configs can be applied, MAC address, interface name should
not be touched.
