This commit fixes crash described in
https://github.com/systemd/systemd/issues/6533
Multiple ExecStart lines are allowed only for oneshot services
anyway so it doesn't make sense to call service_run_next_main() with
services of type other than SERVICE_ONESHOT.
Referring back to reproducer from the issue, previously we didn't observe
this problem because s->main_command was reset after daemon-reload hence
we never reached the assert statement in service_run_next_main().
Fixes#6533
This catches errors like "ninja not found", missing programs etc. early,
instead of silently ignoring them and trying to boot a broken VM.
In install_config_files(), allow some distro specific files to be absent
(such as /etc/sysconfig/init).
All test/TEST* but TEST-02-CRYPTSETUP share the same check_result_qemu()
and test_cleanup(), so move them into test_functions and only override
them in TEST-02-CRYPTSETUP.
Also provide a common test_run() which by default assumes that both QEMU
and nspawn tests are run. Particular tests which don't support either
need to explicitly opt out by setting $TEST_NO_{QEMU,NSPAWN}. Do it this
way around to avoid accidentally forgetting to opt in, and to encourage
test authors to at least always support nspawn.
Automatic rebuilding is removed: it doesn't play well with ninja, because
ninja always writes logs, and even if nothing needs to be built, it will
make the log file owned by root. So let's just remove this, and say that
the user must always do the build first.
I'm also keeping make for the tests, because ninja doesn't play well with
sudo.
Since the build directory is arbitrary, it needs to be specified, e.g.
sudo make BUILD_DIR=/home/zbyszek/src/systemd/build1 -C test/TEST-01-BASIC/
In networkd-test.py, don't assert that the router state is "routable".
While it should eventually become that, we don't wait for it, and thus
at that point it often is "carrier" or "degrated" still. It is also not
really relevant as this only tests the "client" side interface.
generator_add_symlink() is extended to ignore EEXIST. This should be fine
for all existing callers.
There's a small difference in behaviour when adding symlinks in sysv-generator:
the message is more generic and does not include ", ignored". But creation of
symlinks shouldn't ever fail except if things are very wrong, so in practice
this shouldn't matter.
Test needed updating: os.path.exists(os.readlink(link)) only works if the link
is absolute (or if we are in the right directory). Let's just use
os.path.exists(link), which properly tests that the symlink target exists.
Using conf.set() with a boolean argument does the right thing:
either #ifdef or #undef. This means that conf.set can be used unconditionally.
Previously I used '1' as the placeholder value, and that needs to be changed to
'true' for consistency (under meson 1 cannot be used in boolean context). All
checks need to be adjusted.
This is useful on systems like NixOS, where python3 is not in
/usr/bin/python3 as well as for people using alternative ways to
install python such as virtualenv/pyenv.
The indentation for emacs'es meson-mode is added .dir-locals.
All files are reindented automatically, using the lasest meson-mode from git.
Indentation should now be fairly consistent.
This allow test-efi-disk.img to be created under meson.
The invocation of qemu is not converted yet, in particular because the
command-line used in Makefile.am is outdated.
Allow setting bridge port priority in the Bridge section of the network file,
similar to e.g. port path cost setting.
Set the default to an invalid value of 128, and only set the port priority when
it's not 128. Unlike e.g. path cost, zero is a valid priority value.
Add a networkd-test.py to check that bridge port priority is correctly set.
Incidently, fix bridge port cost type and document valid ranges.
On Ubuntu 17.04 (zesty zapus) netcat-openbsd was upgraded from 1.105-7ubuntu1
to 1.130-3, at the same time the defaults got changed from -q0 to -q-1
(infinity) the net result is that `echo A | nc -U' call now hangs, preventing
the testcase to complete. One could use the old default of -q0, but that option
is not available in some netcat implementations. Thus settle to specify -w1
instead to mitigate the testcase hang.
Only one test case is added, but it is enough to check basic sanity of the
code (single-line and binary fields and trusted fields, allocation and freeing).
Moe test-resolve's test data from src/resolve/test-data to
test/test-resolve/ to be consistent with test/test-{execute,path}/. This
will make it easier to make the tests relocatable.
ReadOnlyPaths=, ProtectHome=, InaccessiblePaths= and ProtectSystem= are
about restricting access and little more, hence they should be disabled
if PermissionsStartOnly= is used or ExecStart= lines are prefixed with a
"+". Do that.
(Note that we will still create namespaces and stuff, since that's about
a lot more than just permissions. We'll simply disable the effect of
the four options mentioned above, but nothing else mount related.)
This also adds a test for this, to ensure this works as intended.
No documentation updates, as the documentation are already vague enough
to support the new behaviour ("If true, the permission-related execution
options…"). We could clarify this further, but I think we might want to
extend the switches' behaviour a bit more in future, hence leave it at
this for now.
Fixes: #5308
The script contains the contents of all sys/ test files, and creates
all dirs/links/files when run. This replaces the sys.tar.xz tarball
that contained sys/, so changes to sys files only require a simple
commit in git, instead of checking in an entire new tarball for each
sys/ change.
Instead of keeping all sys/ nodes in a tarball, use a script
"sys-script.py" to create all the sys/ entries.
This adds a script to create that initial "sys-script.py" script, using
an existing sys/ directory, created from the sys.tar.xz contents.
The "sys-script.py" can then be edited or recreated later, when any sys/
files are added or modified; the change will be only a patch to the
"sys-script.py" script in git, instead of forcing git to store a new
binary tarball.
[zj: tests assertions adjusted to the different logic in which masking
of a dependency through one name, does not forbid the dependency
being added through another name.]
add udev-test.pl tests for whitespace in a substituted variable,
to verify the variable whitespace is replaced with underscores.
Tests for the change made by commit 0a10235ed4 ("udev-rules:
perform whitespace replacement for symlink subst values")
/dev/mem isn't necessarily available. Recently, I've encountered arm64
systems that didn't provide raw memory access via /dev/mem. Instead,
let's use /dev/kmsg since we don't support systems w/o it anyway.
In test_resolved_domain_restricted_dns(), add dot domain separator to
negative .lab/.company tests, so that we don't catch these as part of
the host name (like "lxc-labjfr").
Caught in PR #4962
Fix wrong condition test in manager_etc_hosts_lookup(), which caused it to
return an IPv4 answer when an IPv6 question was asked, and vice versa.
Also only return success if we actually found any A or AAAA record.
In systemd-resolved.service(8), point out that /etc/hosts mappings only
affect address-type lookups, not other types.
The test case currently disables DNSSEC in resolved, as there is a bug
where "-t MX" fails due to "DNSSEC validation failed" even after
"downgrading to non-DNSSEC mode". This should be dropped once that bug
gets fixed.
Fixes#4801
Since syntax error are non-fatal, downgrade them to warnings.
Use log_syntax to have uniform formatting including the line number.
State machine states like DATA and MATCH are internal, user-facing
messages should use the names from hwdb(7): match, property, record.
Also change "key/value" to "key-value", since there's no alternative
here, both parts must be present.

squash! hwdb: improve syntax error messages
Because -e was set, we'd exit immediately when systemd-hwdb failed and the
captured error output was never printed. We want to test two things:
that 0 is returned, and that nothing is printed to stderr (to catch
syntax errors in the hwdb).
v2: stop capturing stderr to a variable
v3: capture stderr to a variable and test both error types separately
Sometimes setting the transient hostname does not happen synchronously, so
retry up to five times. It is not yet clear whether this is legitimate
behaviour or an underlying bug, but this will at least show whether the wrong
transient hostname is just a race condition or permanently wrong.
Fixes#4753
This test fails sometimes but it is hard to reproduce, so we need more
information what happens. Set journal log level to "debug" for the entirety of
networkd-test.py, and show networkd's and hostnamed's journals and the DHCP
server log on failure of the two test_transient_hostname* tests. Also sync the
journal before querying it to get more precise output.
This should help with tracking down issue #4753.
systemd-networkd runs as user "systemd-network" and thus is not privileged to
set the timezone acquired from DHCP:
systemd-networkd[4167]: test_eth42: Could not set timezone: Interactive authentication required.
Similarly to commit e8c0de912, add a polkit rule to grant
org.freedesktop.timedate1.set-timezone to the "systemd-network" system user.
Move the polkit rules from src/hostname/ to src/network/ to avoid too many
small distributed policy snippets (there might be more in the future), as it's
easier to specify the privileges for a particular subject in this case.
Add NetworkdClientTest.test_dhcp_timezone() test case to verify this (for
all people except those in Pacific/Honolulu, there the test doesn't prove
anything -- sorry ☺ ).
systemd-networkd runs as user "systemd-network" and thus is not privileged to
set the transient hostname:
systemd-networkd[516]: ens3: Could not set hostname: Interactive authentication required.
Standard polkit *.policy files do not have a syntax for granting privileges to
a user, so ship a pklocalauthority (for polkit < 106) and a JavaScript rules
file (for polkit >= 106) that grants the "systemd-network" system user that
privilege.
Add DnsmasqClientTest.test_transient_hostname() test to networkd-test.py to
cover this. Make do_test() a bit more flexible by interpreting "coldplug==None"
as "test sets up the interface by itself". Change DnsmasqClientTest to set up
test_eth42 with a fixed MAC address so that we can configure dnsmasq to send a
special host name for that.
Fixes#4646
If the "systemctl start" happens at an "unlucky" time such as 1000.9 seconds
and then e. g. runs for 2.6 s (sleep 2 plus the overhead of starting the unit
and waiting for it) the END_SEC would be 1003.5s which would round to 1004,
making the difference 4. On busier testbeds the overhead apparently can take a
bit more than 0.5s. The main point is really that it doesn't wait that much
longer, so "-le 4" seems perfectly fine. We allow up to 1.5s in the subsequent
"wait5fail" test below too.
Fixes#4582
DNS servers which have route-only domains should only be used for
the specified domains. Routing queries about other domains there is a privacy
violation, prone to fail (as that DNS server was not meant to be used for other
domains), and puts unnecessary load onto that server.
Introduce a new helper function dns_server_limited_domains() that checks if the
DNS server should only be used for some selected domains, i. e. has some
route-only domains without "~.". Use that when determining whether to query it
in the scope, and when writing resolv.conf.
Extend the test_route_only_dns() case to ensure that the DNS server limited to
~company does not appear in resolv.conf. Add test_route_only_dns_all_domains()
to ensure that a server that also has ~. does appear in resolv.conf as global
name server. These reproduce #3420.
Add a new test_resolved_domain_restricted_dns() test case that verifies that
domain-limited DNS servers are only being used for those domains. This
reproduces #3421.
Clarify what a "routing domain" is in the manpage.
Fixes#3420Fixes#3421
If the ESP is not mounted with "iocharset=ascii", but with "iocharset=utf8"
(which is for example the default in Debian), the file system becomes case
sensitive. This means that a file created as "FooBarBaz" cannot be accessed as
"foobarbaz" since those are then considered different files.
Moreover, a file created as "FooBar" can then also not be accessed as "foobar",
and it also prevents such a file from being created, as both would use the same
8.3 short name "FOOBAR".
Even though the UEFI specification [0] does give the canonical spelling for
the files mentioned above, not all implementations completely conform to that,
so it's possible that those files would already exist, but with a different
spelling, causing subtle bugs when scanning or modifying the ESP.
While the proper fix would of course be that everybody conformed to the
standard, we can work around this problem by just referencing the files by
their 8.3 short names, i.e. using upper case.
Fixes: #3740

* test: check resolved generated resolv.conf in networkd-test
Directly verify the contents of /run/systemd/resolve/resolv.conf instead of
/etc/resolv.conf. The latter might be a plain file or a symlink to something
else (like Debian's resolvconf output), and in these cases we cannot make
strong assumptions about the contents.
Drop the "/etc/resolv.conf is a symlink" conditions and the "resolv.conf can
have at most three nameservers" alternatives, as we know that resolved always
adds all nameservers.
Explicitly start resolved at the start of a test to ensure that it is running.
* test: get along with existing system search domains in resolv.conf
The previous change has uncovered a bug in the tests: Existing search domains
can exist in resolv.conf which test_search_domains{,_too_long} didn't take into account.
As existing domains take some of the "max 6 domains" and "max 255 chars" limit,
don't expect that the last items from our test data actually appears in the
output, just the first few.
With commit 6f7da49d00 route-only domains do not get put into resolv.conf's
"search" list any more. Add a comment about the tri-state, to clarify its
semantics and why we are passing a bool parameter into an int type. Also add a
test case for it.
If run_qemu() exits with non-zero, this either meant that QEMU was not
available (which should be a SKIP) or that QEMU timed out if $QEMU_TIMEOUT was
set (which then should be a FAIL).
Limit the exit code of run_qemu() to QEMU availability only, and track timeouts
separately through the new $TIMED_OUT variable, which is then checked in
check_result_qemu().
Do the same for $NSPAWN_TIMEOUT and run_nspawn() so that nspawn and QEMU work
similarly.
The result of check_nspawn does not mean much, and this forgot to ask
check_nspawn() whether nspawn can be used at all. This brings
TEST-12-ISSUE-3171 in line with other nspawn tests.
The long name is just too hard to type. We generally should avoid using
acronyms too liberally, if they aren't established enough, but it appears that
"RA" is known well enough. Internally we call the option "ipv6_accept_ra"
anyway, and the kernel also exposes it under this name. Hence, let's rename the
IPv6AcceptRouterAdvertisements= setting and the
[IPv6AcceptRouterAdvertisements] section to IPv6AcceptRA= and [IPv6AcceptRA].
The old setting IPv6AcceptRouterAdvertisements= is kept for compatibility with
older configuration. (However the section [IPv6AcceptRouterAdvertisements] is
not, as it was never available in a published version of systemd.
There are many cgroups-related changes (thanks, @htejun!)
This commit will simplify testing a bit.
Use:
make run UNIFIED_CGROUP_HIERARCHY=yes to enable cgroup-v2
make run UNIFIED_CGROUP_HIERARCHY=no to enable cgroup-v1
Write comments about "too many search domains" and "Total length of all search
domains is too long" just once. Also put it on a separate line, as
resolv.conf(5) only specifies comments in a line by themselves.
This is ugly to do if write_resolv_conf_search() gets called once for every
search domain. So change it to receive the complete OrderedSet instead and do
the iteration by itself.
Add test cases to networkd-test.py.

Due to the substantial interface changes in cgroup unified hierarchy, new IO
settings are introduced. Currently, IO settings apply only to unified
hierarchy and BlockIO to legacy. While the transition is necessary, it's
painful for users to have to provide configs for both. This patch implements
translation from one config set to another for configs which make sense.
* The translation takes place during application of the configs. Users won't
see IO or BlockIO settings appearing without being explicitly created.
* The translation takes place only if there is no config for the matching
cgroup hierarchy type at all.
While this doesn't provide comprehensive compatibility, it should considerably
ease transition to the new IO settings which are a superset of BlockIO
settings.
v2:
- Update test-cgroup-mask.c so that it accounts for the fact that
CGROUP_MASK_IO and CGROUP_MASK_BLKIO move together. Also, test/parent.slice
now sets IOWeight instead of BlockIOWeight.
In this test /etc/fstab is replaced by -.mount unit. This causes
systemd-remount-fs.service to not remount / rw, which in turn causes various
failures becuase /var is not writable. In particular
systemd-tmpfiles-setup.service reports many failures. This is something
to possibly fix on its own (see https://github.com/systemd/systemd/issues/791);
in the meanwhile let's fix this test so that it doesn't fail, since the
point of the test is to check aliases on mount units, and not a ro root.
systemd-udev generated an insane amount of log output at debug level.
It would break TEST-02-CRYPTSETUP by filling the overflowing the disk
(which seems to be a bug in itself!).
WARNING: Image format was not specified for
'/var/tmp/systemd-test.tGi3od/rootdisk.img' and probing guessed raw.
Automatically detecting the format is dangerous for raw images, write
operations on block 0 will be restricted. Specify the 'raw' format
explicitly to remove the restrictions.
Also use unsafe caching mode, we don't care about data integrity here.
~ suffix works fine, but looks to much like it the file is supposed to be
automatically cleaned up. For new versions of configuration files installers
might want to using something that looks more permanent like foobar.new.
So let's add treat ".old" and ".new" as special.
Update test to match.

The manpage of seccomp specify that using seccomp with
SECCOMP_SET_MODE_FILTER will return EACCES if the caller do not have
CAP_SYS_ADMIN set, or if the no_new_privileges bit is not set. Hence,
without NoNewPrivilege set, it is impossible to use a SystemCall*
directive with a User directive set in system mode.
Now, NoNewPrivileges is set if we are in user mode, or if we are in
system mode and we don't have CAP_SYS_ADMIN, and SystemCall*
directives are used.
It's useful when trying to see what the tests are doing.
I hardcoded '-efile' as the option to strace, but in the future
it might be useful to make this configurable.
If there is a lot of initscripts and dependencies between them we might
end generating After= (and similar) lines which are longer then LINE_MAX
and thus rejected by parser in systemd.
