strtoul() parses leading whitespace and an optional sign;
check that the first character is a digit to prevent odd
specifications like "00: 00: 00" and "-00:+00/-1".
This is a different way to implement the fix proposed by commit
a4021390fe suggested by Lennart Poettering.
In this patch we instruct PID1 to not kill "systemctl switch-root" command
started by initrd-switch-root service using the "argv[0][0]='@'" trick.
See: https://www.freedesktop.org/wiki/Software/systemd/RootStorageDaemons/ for
more details.
We had to backup argv[0] because argv is modified by dispatch_verb().
pyparsing uses the system locale by default, which in the case of 'C' (in lots
of build environment) will fail with a UnicodeDecodeError. Explicitly open it
with UTF-8 encoding to guard against this.
"*-*~1" => The last day of every month
"*-02~3..5" => The third, fourth, and fifth last days in February
"Mon 05~07/1" => The last Monday in May
Resolves#3861
With the previous improvements, networkd.service's "After=dbus.service" can now
be dropped. That ordering effectively forced networkd.service to run in late
boot only (dbus.service was rejected to run in early boot in
https://bugs.freedesktop.org/show_bug.cgi?id=98254).
Fixes#4504
If setting the received timezone or transient hostname fails because D-Bus is
not (yet) up, store the data in the Manager object and try again after
connecting to D-Bus.
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 ☺ ).
Since commit 1f0958f640, systemd considers SIGTERM for short-running
services (aka Type=oneshot) as a failure.
This can be an issue with initrd-switch-root.service as the command run by this
service (in order to switch to the new rootfs) may still be running when
systemd does the switch.
However PID1 sends SIGTERM to all remaining processes right before
switching and initrd-switch-root.service can be one of those.
After systemd is reexecuted and its previous state is deserialized, systemd
notices that initrd-switch-root.service was killed with SIGTERM and considers
this as a failure which leads to the emergency shell.
To prevent this, this patch teaches systemd to consider a SIGTERM exit as a
clean one for this service.
It also removes "KillMode=none" since this is pretty useless as the service is
never stopped by systemd but it either exits normally or it's killed by a
SIGTERM as described previously.
lz4 upstream decided to switch to an incompatible numbering scheme
(1.7.3 follows 131, to match the so version).
PKG_CHECK_MODULES does not allow two version matches for the same package,
so e.g. lz4 < 10 || lz4 >= 125 cannot be used. Check twice, once for
"new" numbers (anything below 10 is assume to be new), once for the "old"
numbers (anything above >= 125). This assumes that the "new" versioning
will not get to 10 to quickly. I think that's a safe assumption, lz4 is a
mature project.
Fixed#4690.
When trying to read keyfiles from an encrypted partition to unlock the swap,
a cyclic dependency is generated because systemd can not mount the
filesystem before it has checked if there is a swap to resume from.
Closes#3940
Before this commit, when the main process of a Type=notify service exits the
service would enter a running state without passing through the startup post
state. This meant ExecStartPost= from being executed and allowed follow-up
units to start too early (before the ready notification).
Additionally, when RemainAfterExit=yes is used on a Type=notify service, the
exit status of the main process would be disregarded.
After this commit, an unsuccessful exit of the main process of a Type=notify
service puts the unit in a failed state. A successful exit is inconsequential
in case RemainAfterExit=yes. Otherwise, when no ready notification has been
received, the unit is put in a failed state because it has never been active.
When all processes in the cgroup of a Type=notify service are gone and no ready
notification has been received yet, the unit is also put in a failed state.
Introduce a SERVICE_FAILURE_PROTOCOL error type for when a service does
not follow the protocol.
This error type is used when a pid file is expected, but not delivered.
Given that other file systems (notably: xfs) support reflinks these days, let's
extend the file system snapshotting logic to fall back to plan copies or
reflinks when full btrfs subvolume snapshots are not available.
This essentially makes "systemd-nspawn --ephemeral" and "systemd-nspawn
--template=" available on non-btrfs subvolumes. Of course, both operations will
still be slower on non-btrfs than on btrfs (simply because reflinking each file
individually in a directory tree is still slower than doing this in one step
for a whole subvolume), but it's probably good enough for many cases, and we
should provide the users with the tools, they have to figure out what's good
for them.
Note that "machinectl clone" already had a fallback like this in place, this
patch generalizes this, and adds similar support to our other cases.
When mountint a loopback image, we need a temporary root directory we can mount
stuff to. Make sure to actually remove it when exiting, so that we don't leave
stuff around in /tmp unnecessarily.
See: #4664
Previously --ephemeral was only supported with container trees in btrfs
subvolumes (i.e. in combination with --directory=). This adds support for
--ephemeral in conjunction with disk images (i.e. --image=) too.
As side effect this fixes that --ephemeral was accepted but ignored when using
-M on a container that turned out to be an image.
Fixes: #4664
@filesystem groups various file system operations, such as opening files and
directories for read/write and stat()ing them, plus renaming, deleting,
symlinking, hardlinking.
This changes the return value a bit: 1 will be returned if the value is
changed. But the return value was not documented, and the change should
be for the good anyway. Current callers don't care.
Never propagate DNS/NTP servers on the local link via the DHCP server. The
DNS/NTP servers 0.0.0.0 and 127.0.0.1 only make sense in the local context,
hence never propagate them automatically to other hosts.
Fixes: #4524
DNS servers must be specified as IP addresses, hence let's store them as that
internally, so that they are guaranteed to be fully normalized always, and
invalid data cannot be stored.
Let's reorder them a bit, so that stuff that belongs together semantically is
placed together (in particular, move the various DHCP "use" booleans together).
