Luca Boccassi 71ad75f306 sysext: install in /usr/lib/systemd/ for now
This is a brand new binary, and the CI packaging doesn't pick it up,
causing the upstream testrun to fail (sysext is pulled in by the unit).

Lennart Poettering 205e5bcc1c units: add systemd-sysext.service unit for auto-activating extensions at boot
We'll leave this as opt-in (i.e. a unit that must be enabled
explicitly), since this is supposed to be a debug/developer feature
primarily, and thus no be around in regular production systems.

Gaël PORTAY 08b04ec7e7 veritysetup-generator: add support for veritytab
This adds the support for veritytab.

The veritytab file contains at most five fields, the first four are
mandatory, the last one is optional:
 - The first field contains the name of the resulting verity volume; its
   block device is set up /dev/mapper/</filename>.
 - The second field contains a path to the underlying block data device,
   or a specification of a block device via UUID= followed by the UUID.
 - The third field contains a path to the underlying block hash device,
   or a specification of a block device via UUID= followed by the UUID.
 - The fourth field is the roothash in hexadecimal.
 - The fifth field, if present, is a comma-delimited list of options.
   The following options are recognized only: ignore-corruption,
   restart-on-corruption, panic-on-corruption, ignore-zero-blocks,
   check-at-most-once and root-hash-signature. The others options will
   be implemented later.

Also, this adds support for the new kernel verity command line boolean
option "veritytab" which enables the read for veritytab, and the new
environment variable SYSTEMD_VERITYTAB which sets the path to the file
veritytab to read.

Daan De Meyer 4ad303fddd meson: Optimize add-wants targets
Instead of invoking meson-add-wants.sh once for each wants that has
to be added, we pass all wants to a single invocation of
meson-add-wants.sh and in meson-add-wants.sh, loop over the
arguments.

This saves about 300ms on the install step.

Zbigniew Jędrzejewski-Szmek 60e4fb4240 hostnamed,shared/hostname-setup: expose the origin of the current hostname
In hostnamed this is exposed as a dbus property, and in the logs in both
places.

This is of interest to network management software and such: if the fallback
hostname is used, it's not as useful as the real configured thing. Right now
various programs try to guess the source of hostname by looking at the string.
E.g. "localhost" is assumed to be not the real hostname, but "fedora" is. Any
such attempts are bound to fail, because we cannot distinguish "fedora" (a
fallback value set by a distro), from "fedora" (received from reverse dns),
from "fedora" read from /etc/hostname.

/run/systemd/fallback-hostname is written with the fallback hostname when
either pid1 or hostnamed sets the kernel hostname to the fallback value. Why
remember the fallback value and not the transient hostname in /run/hostname
instead?
We have three hostname types: "static", "transient", fallback".
– Distinguishing "static" is easy: the hostname that is set matches what
  is in /etc/hostname.
– Distingiushing "transient" and "fallback" is not easy. And the
  "transient" hostname may be set outside of pid1+hostnamed. In particular,
  it may be set by container manager, some non-systemd tool in the initramfs,
  or even by a direct call. All those mechanisms count as "transient". Trying
  to get those cases to write /run/hostname is futile. It is much easier to
  isolate the "fallback" case which is mostly under our control.
And since the file is only used as a flag to mark the hostname as fallback,
it can be hidden inside of our /run/systemd directory.

Franck Bui 07ccf434e7 units: restore sysfs conditions in sys-fs-fuse-connections.mount and sys-kernel-config.mount
Commit 42cc2855ba incorrectly removed the condition on sysfs in both
sys-fs-fuse-connections.mount and sys-kernel-config.mount. However there are
still needed in case modprobe of one of these modules is intentionally skipped
(due to lack of privs for example).

This patch restores the 2 conditions which should be safe for the common case,
since all conditions are only checked after all deps ordered before are
complete.

Follow-up for 42cc2855ba.
2020-11-21 01:10:17 +09:00
Franck Bui 42cc2855ba units: wait until some fs modules are entirely loaded before mounting their corresponding filesystem
udev requests to start the fs mount units when their respective module is
loaded. For that it monitors uevents of type "ADD" for the relevant fs modules.

However the uevent is sent by the kernel too early, ie before the init() of the
module is called hence before directories in /sys/fs/ are created.

This patch workarounds adds "Requires/After=modprobe@<fs-module>.service" to
the mount unit, which means that modprobe(8) will be called once the fs module
is announced to be loaded. This sounds pointless, but given that modprobe only
returns after the initialization of the module is complete, it should
workaround the issue.

As a side effect, the module will be automatically loaded if the mount unit is
started manually.

Fixes #17586.

Franck Bui b3e32582f6 Revert "units: skip modprobe@.service if the unit appears to be already loaded"
This reverts commit 9cbf1e58f9.

The presence of /sys/module/%I directory can't be used to assert that the load
of a given module is complete and therefore the call to modprobe(8) can be
skipped. Indeed this directory is created before the init() function of the
module is called.

Users of modprobe@.service needs to be sure that once this service returns the
module is fully operational.

Jonathan Lebon e921ebb57e units: unconditionally pull in remote-cryptsetup.target in the initramfs
[zjs: Replaces #17149.

I took half of the patch in
https://github.com/systemd/systemd/pull/17149#issuecomment-698399194,
hence I'm keeping Jonathan's authorship.

The original reasoning for 6c5496c492 was that we
enable remote-cryptsetup.target via presets, and since presets are not used for
the initrd, we need a different target. But since parts of the unit and target
tree are shared between the initramfs and the main system, we can't just create
a separate target for the initramfs. All the targets that depend on this one
would need to be split also. That condition is true for initrd-fs.target, but
not for sysinit.target.

So let's instead just uncoditionally pull in remote-cryptsetup.target in the
initramfs. It should normally be empty, so there should be no impact on boots
that don't have units in the target.

Jonathan's patch used initrd-root-fs.target, this version instead uses
initrd-root-device.target. initrd-root-device.target is ordered before
sysroot.mount, which means that the decrypted devices will be available earlier
too.]

Jonathan Lebon 6c5496c492 units: add initrd-cryptsetup.target
For encrypted block devices that we need to unlock from the initramfs,
we currently rely on dracut shipping `cryptsetup.target`. This works,
but doesn't cover the case where the encrypted block device requires
networking (i.e. the `remote-cryptsetup.target` version). That target
however is traditionally dynamically enabled.

Instead, let's rework things here by adding a `initrd-cryptsetup.target`
specifically for initramfs encrypted block device setup. This plays the
role of both `cryptsetup.target` and `remote-cryptsetup.target` in the
initramfs.

Then, adapt `systemd-cryptsetup-generator` to hook all generated
services to this new unit when running from the initrd. This is
analogous to `systemd-fstab-generator` hooking all mounts to
`initrd-fs.target`, regardless of whether they're network-backed or not.

Lennart Poettering d1f6e01e47 homed: explicitly deactivate all home directories on shutdown
Let's explicitly deactivate all home dirs on shutdown, in order to
properly synchronizing unmounting and avoiding blocking devices.

Previously, we'd rely on automatic deactivation when home directories
become unused. However, that scheme is asynchronous, and ongoing
deactviations might conflicts with attempts to unmount /home. Let's fix
that by providing an explicit service systemd-homed-activate.service
whose only job is to have a ExecStop= line that explicitly deactivates
all home directories on shutdown. This service can the be ordered after
home.mount and similar, ensuring that we'll first deactivate all homes
before deactivating /home itself during shutdown.

This is kept separate from systemd-homed.service so that it is possible
to restart systemd-homed.service without deactivating all home
directories.

networkd is started via `systemctl start systemd-networkd.service`.
A Requires is not strictly necessary, as networkd still ships the
non-socket activation code. Should this code be removed one day, the
Wants should be bumped to Requires accordingly.

Lennart Poettering bbac7da2b3 units: order systemd-user-sessions.service after home.mount
This should make /home as automount work reasonably well.

If /home is an automount this has little effect at boot, because if the
automount is not triggered it doesn't matter how the associated mount is
ordered.

It does matter at shutdown however, where home.mount is likely active
now. There the ordering means we'll end sessions first, and only then
deactivate home.mount.

Zbigniew Jędrzejewski-Szmek 362a55fc14 Bump /tmp size back to 50% of RAM
This should be enough to fix https://bugzilla.redhat.com/show_bug.cgi?id=1856514.
But the limit should be significantly higher than 10% anyway. By setting a
limit on /tmp at 10% we'll break many reasonable use cases, even though the
machine would deal fine with a much larger fraction devoted to /tmp.
(In the first version of this patch I made it 25% with the comment that
"Even 25% might be too low.". The kernel default is 50%, and we have been using
that seemingly without trouble since https://fedoraproject.org/wiki/Features/tmp-on-tmpfs.
So let's just make it 50% again.)

See 7d85383edb.

(Another consideration is that we learned from from the whole initiative with
zram in Fedora that a reasonable size for zram is 0.5-1.5 of RAM, and that pretty
much all systems benefit from having zram or zswap enabled. Thus it is reasonable
to assume that it'll become widely used. Taking the usual compression effectiveness
of 0.2 into account, machines have effective memory available of between
1.0 - 0.2*0.5 + 0.5 = 1.4 (for zram sized to 0.5 of RAM) and
1.0 - 0.2*1.5 + 1.5 = 2.2 (for zram 1.5 sized to 1.5 of RAM) times RAM size.
This means that the 10% was really like 7-4% of effective memory.)

A comment is added to mount-util.h to clarify that tmp.mount is separate.

Lennart Poettering 871dc8d644 homed: enable userdb too if homed is requested
Strictly speaking you can run homed without userdb. But it doesn't

concepts, just for different sets of users. Let's hence disable both
automatically by default if homed is requested.

(We don't do the reverse: opting into userdbd shouldn't mean that you
are OK with homed.)

And of course, users can always deviate from our defaults easily, and
turn off userbd again right-away if they don't like it, and things will
generally work.

Topi Miettinen 7d85383edb tree-wide: add size limits for tmpfs mounts
Limit size of various tmpfs mounts to 10% of RAM, except volatile root and /var
to 25%. Another exception is made for /dev (also /devs for PrivateDevices) and
/sys/fs/cgroup since no (or very few) regular files are expected to be used.

In addition, since directories, symbolic links, device specials and xattrs are
not counted towards the size= limit, number of inodes is also limited
correspondingly: 4MB size translates to 1k of inodes (assuming 4k each), 10% of
RAM (using 16GB of RAM as baseline) translates to 400k and 25% to 1M inodes.

Because nr_inodes option can't use ratios like size option, there's an
unfortunate side effect that with small memory systems the limit may be on the
too large side. Also, on an extremely small device with only 256MB of RAM, 10%
of RAM for /run may not be enough for re-exec of PID1 because 16MB of free
space is required.

Lennart Poettering 846acb6798 binfmt: also unregister binfmt entries from unit
We unregister binfmt_misc twice during shutdown with this change:

1. A previous commit added support for doing that in the final shutdown
   phase, i.e. when we do the aggressive umount loop. This is the robust
   thing to do, in case the earlier ("clean") shutdown phase didn't work
   for some reason.

2. This commit adds support for doing that when systemd-binfmt.service
   is stopped. This is a good idea so that people can order mounts
   before the service if they want to register binaries from such
   mounts, as in that case we'll undo the registration on shutdown
   again, before unmounting those mounts.

And all that, just because of that weird "F" flag the kernel introduced
that can pin files...

Lennart Poettering aade0c3b6e Revert "units: make systemd-repart.service installable"
This reverts commit 7e1ed1f3b2.

systemd-repart is not a user service that should be something people
enable/disable, instead it should just work if there's configuration for
it. It's like systemd-tmpfiles, systemd-sysusers, systemd-load-modules,
systemd-binfmt, systemd-systemd-sysctl which are NOPs if they have no
configuration, and thus don't hurt, but cannot be disabled since they
are too deep part of the OS.

This doesn't mean people couldn't disable the service if they really
want to, there's after all "systemctl mask" and build-time disabling,
but those are OS developer facing instead of admin facing, that's how it
should be.

Note that systemd-repart is in particular an initrd service, and so far
enable/disable state of those is not managed anyway via "systemctl
enable/disable" but more what dracut decides to package up and what not.

The first part was reverted in 750e550eba.
The problem starts when s-v-s.s is pulled in by something that is then pulled
in by sysinit.target. Every time a unit is started, systemd recursively checks
all dependencies, and since sysinit.target is pull in by almost anything, we'll
start s-v-s.s over and over. In particular, plymouth-start.service currently
has Wants=s-v-s.s and After=s-v-s.s.
