When parsing and installing binaries mentioned in Exec*= lines the
5ed0dcf4d5 commit added parsing logic to drop
prefixes, including handling duplicate exclamation marks. But this did not
handle arbitrary combination of multiple prefixes, ie. StartExec=+-/bin/sh was
parsed as -/bin/sh which then would fail to install.
Instead of using egrep and shell replacements, replace both with sed command
that does it all. This sed script extract a group of characters starting with a
/ up to the first space (if any) after the equals sign. This correctly handles
existing non-prefixed, prefixed, multiple-prefixed commands.
About half commands seem to repeat themself, thus sort -u cuts the list of
binaries to install about in half.
To validate change of behaviour both old and new functions were modified to
echo parsed binaries into separate files, and then diffed. The incorrect
-/bin/sh was missing in the new output.
Without this patch tests fail on default Ubuntu installs.
Both SO_SNDBUFFORCE and SO_RCVBUFFORCE requires capability 'net_admin'.
If this capability is not granted to the service the first attempt to increase
the recv/snd buffers (via sd_notify()) with SO_RCVBUFFORCE/SO_SNDBUFFORCE will
fail, even if the requested size is lower than the limit enforced by the
kernel.
If apparmor is used, the DENIED logs for net_admin will show up. These log
entries are seen as red warning light, because they could indicate that a
program has been hacked and tries to compromise the system.
It would be nicer if they can be avoided without giving services (relying on
sd_notify) net_admin capability or dropping DENIED logs for all such services
via their apparmor profile.
I'm not sure if sd_notify really needs to forcibly increase the buffer sizes,
but at least if the requested size is below the kernel limit, the capability
(hence the log entries) should be avoided.
Hence let's first ask politely for increasing the buffers and only if it fails
then ignore the kernel limit if we have sufficient privileges.
Followup to commit 13cf422e04 ("user@.service: don't kill user manager at runlevel switch")
I think there's a general rule that units with `StopWhenUnneeded=yes` need
`IgnoreOnIsolate=yes`... But it doesn't apply to `suspend.target` and friends.
`printer.target` and friends break on isolate even if we apply the rule[1].
That just leaves `graphical-session.target`, which is a user service.
"isolate" is *mostly* a weird attempt to emulate runlevels, so I decided
not to worry about it for user services.
[1] https://github.com/systemd/systemd/issues/6505#issuecomment-320644819
Loggin in as root user and then switching the runlevel results in a
stop of the user manager, even though the user ist still logged in.
That leaves a broken user session.
Adding "IgnoreOnIsolate=true" to user@.service fixes this.
When $XDG_DATA_DIRS is unset, then, the default value
'/usr/local/share:/usr/share' is used.
When $XDG_DATA_DIRS contain the default paths but the order
is inverted: '/usr/share:/usr/local/share', then test-path-lookup fails.
Fixes#10002.
This makes it so that tests no longer need to know the absolute paths to the
source and build dirs, instead using the systemd-runtest.env file to get these
paths when running from the build tree.
Confirmed that test-catalog works on `ninja test`, when called standalone and
also when the environment file is not present, in which case it will use the
installed location under /usr/lib/systemd/catalog.
The location can now also be overridden for this test by setting the
$SYSTEMD_CATALOG_DIR environment variable.
This simplifies get_testdata_dir() to simply checking for an environment
variable, with an additional function to locate a systemd-runtest.env file in
the same directory as the test binary and reading environment variable
assignments from that file if it exists.
This makes it possible to:
- Run `ninja test` from the build dir and have it use ${srcdir}/test for
test unit definitions.
- Run a test directly, such as `build/test-execute` and have it locate
them correctly.
- Run installed tests (from systemd-tests package) and locate the test
units in the installed location (/usr/lib/systemd/tests/testdata), in
which case the absence of the systemd-runtest.env file will have
get_testdata_dir() use the installed location hardcoded into the
binaries.
Explicit setting of $SYSTEMD_TEST_DATA still overrides the contents of
systemd-runtest.env.
This also unifies __filter_units_by_property() and
__filter_units_by_properties(), and makes completion for 'restart',
'reload' or 'stop' show more candidates.
Actually check the return code from logind_schedule_shutdown() and proceed to
immediate shutdown if that fails. Negative return codes can be returned if
systemctl is compiled without logind support, or if logind otherwise failed
(either too old, disabled/masked, or it is incomplete
systemd-shim/systemd-service implementation).
An assertion in dhcp_network_bind_raw_socket() is triggered when
starting an sd_dhcp_client without setting a MAC address first.
- sd_dhcp_client_start()
- client_start()
- client_start_delayed()
- dhcp_network_bind_raw_socket()
In that case, the arp-type and MAC address is still unset. Note that
dhcp_network_bind_raw_socket() already checks for a valid arp-type
and MAC address below, so we should just gracefully return -EINVAL.
Maybe sd_dhcp_client_start() should fail earlier when starting without
MAC address. But the failure here will be correctly propagated and
the start aborted.

When a network namespace is needed, /sys is mounted as tmpfs (see commit
d8fc6a000f for details).
But in this case mode 755 was used as initial permissions for /sys whereas the
default mode for sysfs is 555.
In practice using 755 doesn't have any impact because /sys is mounted read-only
too but for consistency, let's use the correct mode.
Fixes: #10050
