We should try to keep the unbreakable lines below 80 columns.
It's not always possible of course.
Also, use the dl.fp.o alias instead of a specific mirror.
There was a missing dependency and one with the wrong type. Additionally, refer
to DefaultDependencies= once instead of twice, without a vague reference in the
first one that doesn't mention that the value matters.
Fixes#5226.
Add a bit of code that tries to get the right parameter order in place
for some of the better known architectures, and skips
restrict_namespaces for other archs.
This also bypasses the test on archs where we don't know the right
order.
In this case I didn't bother with testing the case where no filter is
applied, since that is hopefully just an issue for now, as there's
nothing stopping us from supporting more archs, we just need to know
which order is right.
Fixes: #5241
The code make the following assertion: when freeing a event loop object
(usually it's done after exiting from the main event loop), no signal events
are still queued and are pending.
This assertion can be found in event_unmask_signal_data() with
"assert(!d->current);" assertion.
It appears that this assertion can be wrong at least in a specific case
described below.
Consider the following example which is inspired from udev: a process defines 3
source events: 2 are created by sd_event_add_signal() and 1 is created by
sd_event_add_post().
1. the process receives the 2 signals consecutively so that signal 'A' source
event is queued and pending. Consequently the post source event is also
queued and pending. This is done by sd_event_wait().
2. The callback for signal 'A' is called by sd_event_dispatch().
3. The next call to sd_event_wait() will queue signal 'B' source event.
4. The callback for the post source event is called and calls sd_event_exit().
5. the event loop is exited.
6. freeing the event loop object will lead to the assertion failure in
event_unmask_signal_data().
This patch simply removes this assertion as it doesn't seem to be a
bug if the signal data still reference a signal source at this point.
Add a new --pivot-root argument to systemd-nspawn, which specifies a
directory to pivot to / inside the container; while the original / is
pivoted to another specified directory (if provided). This adds
support for booting container images which may contain several bootable
sysroots, as is common with OSTree disk images. When these disk images
are booted on real hardware, ostree-prepare-root is run in conjunction
with sysroot.mount in the initramfs to achieve the same results.
The compiler warning is a false positive, since n_addresses is always
initialised on the success path from parse_argv(), but the compiler
obviously can’t work that out.
Fixes:
src/test/test-nss.c:426:9: warning: 'n_addresses' may be used uninitialized in this function [-Wmaybe-uninitialized]
On i386 we block the old mmap() call entirely, since we cannot properly
filter it. Thankfully it hasn't been used by glibc since quite some
time.
Fixes: #5240
The flag is originally defined for "basic data partitions", but not for the
ESP. We reuse it for the various partitions defined by the Discoverable
Partitions Spec, but it isn't defined for the ESP, hence don't check for
it. Instead, do check for GPT_FLAG_NO_BLOCK_IO_PROTOCOL, as that flag
actually is defined for all partition types, and recommended to use by
the UEFI spec.
Fixes: #5218
[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.]

Essentially, instead of sequentially adding deps based on all symlinks
encountered in .wants and .requires dirs for each name and each unit file load
path, iteratate over the load paths and unit names gathering symlinks, then
order them based on priority, and then iterate over the final list, adding
dependencies.
This patch doesn't change the logic too much, except that the order in which
dependencies are applied might be different. It wasn't defined before, so that
not really a change. Adding filtering on the symlinks is left for later
patches.
The --help text currently uses the "--umount" spelling, hence to the
same in the man page too.
And let's settle on "umount" instead of "unmount" here, since most folks
probably expect that when typing in a command, as util-linux' tool is
called "umount" after all, and so is the symlink "systemd-umount" we
install.
If the /var/log/journal directory is created with rigths 700, the application
of an ACL rules without any primary group right sets it to 0. A chmod 755 on
this file will then only set the ACL mask and let the ACL primary group right
to 0. The directory is then unreadable for the primary group.
This patch explicitly sets the primary group to avoid this problem.
Fixes#5264.
If a unit foobar@.service stored below /usr is instantiated via a
symlink foobar@quux.service also below /usr, then we should consider the
instance statically enabled, while the template itself should continue
to be considered enabled/disabled/static depending on its [Install]
section.
In order to implement this we'll now look for enablement symlinks in all
unit search paths, not just in the config and runtime dirs.
Fixes: #5136
Before this patch, if we'd encounter an instance or template symlink
while traversing a chain of symlinks we'd fill in the instance name and
retry the iteration. This makes no sense if the resulting name is
actually the same as we are coming from, as we'd just spin a couple of
times in the loop, until the UNIT_FILE_FOLLOW_SYMLINK_MAX iteration
limit is hit.
Fix this, by accepted the symlink as it is, if it identical to what we
filled in.
The third paragraph of the Description already linked to
systemd.resource-control(5), but it was missing from the list of
additional options for the [Service] section.
This slightly extends the roothash loading logic to first check for a
user.verity.roothash extended attribute on the image file. If it exists,
it is used as Verity root hash and the ".roothash" file is not used.
This should improve the chance that the roothash is retained when the
file is moved around, as the data snippet is attached directly to the
image file. The field is still detached from the file payload however,
in order to make sure it may be trusted independently.
This does not replace the ".roothash" file loading, it simply adds a
second way to retrieve the data.
Extended attributes are often a poor choice for storing metadata like
this as it is usually difficult to discover for admins and users, and
hard to fix if it ever gets out of sync. However, in this case I think
it's safe as verity implies read-only access, and thus there's little
chance of it to get out of sync.
This makes nspawn's logic of automatically discovering the root hash of
an image file generic, and then reuses it in systemd-dissect and in
PID1's RootImage= logic, so that verity is automatically set up whenever
we can.
This is similar to RootDirectory= but mounts the root file system from a
block device or loopback file instead of another directory.
This reuses the image dissector code now used by nspawn and
gpt-auto-discovery.
If the dissected image contains symlinks for the mount points we need we
need to make sure to follow this with chase_symlinks() so that we don't
leave the image.
5327c910d2 claimed to add support for "+"
for prefixing paths with the configured RootDirectory=. But actually it
only implemented it in the backend, it did not add support for it to the
configuration file parsers. Fix that now.
This adds a boolean unit file setting MountAPIVFS=. If set, the three
main API VFS mounts will be mounted for the service. This only has an
effect on RootDirectory=, which it makes a ton times more useful.
(This is basically the /dev + /proc + /sys mounting code posted in the
original #4727, but rebased on current git, and with the automatic logic
replaced by explicit logic controlled by a unit file setting)
