We parse the string supplied in NTP_SERVERS during configuration under an
assert_se(). Right now we will accept pretty much anything there, but in case
we are more picky in the future, add a simple test which checks that we can
actually parse whatever is in NTP_SERVERS so that we don't fail the assertion
at runtime.
This test is mostly a compilation test that checks that various defines in
sd-bus-vtable.h are valid C++. The code is executed, but the results are not
checked (apart from sd-bus functions not returning an error). test-bus-objects
contains pretty extensive tests for this functionality.
The C++ version is only added to meson, since it's simpler there.
Because of the .cc extension, meson will compile the executable with c++.
This test is necessary to properly check the macros in sd-bus-vtable.h. Just
running the headers through g++ is not enough, because the macros are not
exercised.
Follow-up for #5941.
Now that meson builds require a separate build dir, everybody's bound to have
at least one. So let's accept the convention that build*/ is for builds, and
apply a blanket ignore rule, we shouldn't have any important files named build*
in the main directory.
Why the strange name: the prefix is necessary to follow our own advice that
environment generators should have numerical prefixes. I also put -d- in the
name because otherwise the name was very easy to mistake with
systemd.environment-generator. This additional letter clarifies that this
on special generator that supports environment.d files.
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).
This adds a generator and a small service that will look for "roothash="
on the kernel command line and use it for setting up a very partition
for the root device.
This provides similar functionality to nspawn's existing --roothash=
switch.
This adds support for a new kernel command line option "systemd.volatile=" that
provides the same functionality that systemd-nspawn's --volatile= switch
provides, but for host systems (i.e. systems booting with a kernel).
It takes the same parameter and has the same effect.
In order to implement systemd.volatile=yes a new service
systemd-volatile-root.service is introduced that only runs in the initrd and
rearranges the root directory as needed to become a tmpfs instance. Note that
systemd.volatile=state is implemented different: it simply generates a
var.mount unit file that is part of the normal boot and has no effect on the
initrd execution.
The way this is implemented ensures that other explicit configuration for /var
can always override the effect of these options. Specifically, the var.mount
unit is generated in the "late" generator directory, so that it only is in
effect if nothing else overrides it.
This adds a small tool that may be used to look into OS images, and mount them
to any place. This is mostly a friendlier version of test-dissect-image.c. I am
not sure this should really become a proper command of systemd, hence for now
do not install it into bindir, but simply libexecdir.
This tool is already pretty useful since you can mount image files with it,
honouring the various partitions correctly. I figure this is going to become
more interesting if the dissctor learns luks and verity support.
This adds two new APIs to systemd:
- loop-util.h is a simple internal API for allocating, setting up and releasing
loopback block devices.
- dissect-image.h is an internal API for taking apart disk images and figuring
out what the purpose of each partition is.
Both APIs are basically refactored versions of similar code in nspawn. This
rework should permit us to reuse this in other places than just nspawn in the
future. Specifically: to implement RootImage= in the service image, similar to
RootDirectory=, but operating on a disk image; to unify the gpt-auto-discovery
generator code with the discovery logic in nspawn; to add new API to machined
for determining the OS version of a disk image (i.e. not just running
containers). This PR does not make any such changes however, it just provides
the new reworked API.
The reworked code is also slightly more powerful than the nspawn original one.
When pointing it to an image or block device with a naked file system (i.e. no
partition table) it will simply make it the root device.
Let's take inspiration from bluez's ELL library, and let's move our
cryptographic primitives away from libgcrypt and towards the kernel's AF_ALG
cryptographic userspace API.
In the long run we should try to remove the dependency on libgcrypt, in favour
of using only the kernel's own primitives, however this is unlikely to happen
anytime soon, as the kernel does not provide Elliptic Curve APIs to userspace
at this time, and we need them for the DNSSEC cryptographic.
This commit only covers hashing for now, symmetric encryption/decryption or
even asymetric encryption/decryption is not available for now.
"khash" is little more than a lightweight wrapper around the kernel's AF_ALG
socket API.
This adds "systemd-mount" which is for transient mount and automount units what
"systemd-run" is for transient service, scope and timer units.
The tool allows establishing mounts and automounts during runtime. It is very
similar to the usual /bin/mount commands, but can pull in additional
dependenices on access (for example, it pulls in fsck automatically), an take
benefit of the automount logic.
This tool is particularly useful for mount removable file systems (such as USB
sticks), as the automount logic (together with automatic unmount-on-idle), as
well as automatic fsck on first access ensure that the removable file system
has a high chance to remain in a fully clean state even when it is unplugged
abruptly, and returns to a clean state on the next re-plug.
This is a follow-up for #2471, as it adds a simple client-side for the
transient automount logic added in that PR.
In later work it might make sense to invoke this tool automatically from udev
rules in order to implement a simpler and safer version of removable media
management á la udisks.
When converting an empty x11 variant, we would not delete vconsole mapping
properly.
find_legacy_keymap() is made non-static. I think it's important to be able to
test it. In principle we could also test it through the higher-level interface
of x11_convert_to_vconsole, but x11_convert_to_vconsole also uses
find_converted_keymap, and it's better to test at this lower level.
Note that find_legacy_keymap might be a bit of a misnomer, because we'd probably
want to keep kbd-model-map even if the "legacy" layouts went away. So we might
want to change this name, but I'm leaving that for another commit.
This adds a new --private-userns-chown switch that may be used in combination
with --private-userns. If it is passed a recursive chmod() operation is run on
the OS tree, fixing all file owner UID/GIDs to the right ranges. This should
make user namespacing pretty workable, as the OS trees don't need to be
prepared manually anymore.
The source file name and the binary name were mismatched.
Rename binary to match.
Make the test exit with TEST_SKIP if the data is missing or we
have no permissions. Otherwise, the data will be printed, which
should be safe to enable by default.
