The article "a" goes before consonant sounds and "an" goes before vowel
sounds. This commit changes an to a for UKI, UDP, UTF-8, URL, UUID, U-Label, UI
and USB, since they start with the sound /ˌjuː/.
In various tools and services we have a per-system and per-user concept.
So far we sometimes used a boolean indicating whether we are in system
mode, or a reversed boolean indicating whether we are in user mode, or
the LookupScope enum used by the lookup path logic.
Let's address that, in introduce a common enum for this, we can use all
across the board.
This is mostly just search/replace, no actual code changes.
Pass the joined arguments to polkit as command_line property like
pkexec does. Obviously not exactly perfect as it lacks quoting. Good
enough for polkit rules to check whether a program was called with
or without arguments though.
-1 was used everywhere, but -EBADF or -EBADFD started being used in various
places. Let's make things consistent in the new style.
Note that there are two candidates:
EBADF 9 Bad file descriptor
EBADFD 77 File descriptor in bad state
Since we're initializating the fd, we're just assigning a value that means
"no fd yet", so it's just a bad file descriptor, and the first errno fits
better. If instead we had a valid file descriptor that became invalid because
of some operation or state change, the other errno would fit better.
In some places, initialization is dropped if unnecessary.
machine: Add APIs CopyTo[Machine]WithFlags + CopyFrom[Machine]WithFlags
- Same API to those without `WithFlags` (except this can take flags)
- Initially, only a flag to allow replacing a file if it already exists
* machine: update to use new-style sd-bus macros
Replace old SD_BUS_METHOD_WITH_NAMES and SD_BUS_SIGNAL_WITH_NAMES macros to
the new SD_BUS_METHOD_WITH_ARGS and SD_BUS_SIGNAL_WITH_ARGS macros.
Meson test, mkosi test image and running machinectl after build returned
no error. But since I don't have any virtual machines or containers, I'm not
sure how to test the changes thoroughly.
Let's define two helpers strdupa_safe() + strndupa_safe() which do the
same as their non-safe counterparts, except that they abort if called
with allocations larger than ALLOCA_MAX.
This should ensure that all our alloca() based allocations are subject
to this limit.
afaics glibc offers three alloca() based APIs: alloca() itself,
strndupa() + strdupa(). With this we have now replacements for all of
them, that take the limit into account.
(Well, at least the ones where that makes sense. Where it does't make
sense are the ones that re invoked on the root path, which cannot
possibly be a symlink.)
Previously we'd use a directory /run/systemd/nspawn/incoming for
accepting mounts to propagate from the host. This is a bit weird, since
we have a shared namespace: /run/systemd/ contains both stuff managed by
the surround nspawn as well as from the systemd inside.
We now have the /run/host/ hierarchy that has special stuff we want to
pass from host to container. Let's make use of that here, and move this
directory here too.
This is not a compat breakage, since the payload never interfaces with
that directory natively: it's only nspawn and machined that need to
agree on it.
This allows more granular access control in PolicyKit rules, similar to
/etc/sudoers, for polkit actions:
* org.freedesktop.machine1.host-shell
* org.freedesktop.machine1.shell
Example configuration, place in /etc/polkit-1/rules.d/
polkit.addRule(function(action, subject) {
if (action.id == "org.freedesktop.machine1.host-shell"
&& subject.user == "my-user"
&& action.lookup("user") == "target-user") {
return polkit.Result.YES;
}
});
This is the opposite of RegisterMachine: machined knows that the machine is
"gone", but doesn't do anything on its own. We already had TerminateMachine,
but that would stop the unit, which isn't always wanted.
chase_symlinks() would return negative on error, and either a non-negative status
or a non-negative fd when CHASE_OPEN was given. This made the interface quite
complicated, because dependning on the flags used, we would get two different
"types" of return object. Coverity was always confused by this, and flagged
every use of chase_symlinks() without CHASE_OPEN as a resource leak (because it
would this that an fd is returned). This patch uses a saparate output parameter,
so there is no confusion.
(I think it is OK to have functions which return either an error or an fd. It's
only returning *either* an fd or a non-fd that is confusing.)
Allocating a pty is done in a couple of places so let's introduce a new helper
which does the job.
Also the new function, as well as openpt_in_namespace(), returns both pty
master and slave so the callers don't need to know about the pty slave
allocation details.
For the same reasons machine_openpt() prototype has also been changed to return
both pty master and slave so callers don't need to allocate a pty slave which
might be in a different namespace.
Finally openpt_in_namespace() has been renamed into
openpt_allocate_in_namespace().
This doesn't really change much, but feels more correct to do, as it
ensures that all messages currently queued in the bus connections are
definitely unreffed and thus destryoing of the connection object will
follow immediately.
Strictly speaking this change is entirely unnecessary, since nothing
else could have acquired a ref to the connection and queued a message
in, however, now that we have the new sd_bus_close_unref() helper it
makes a lot of sense to use it here, to ensure that whatever happens
nothing that might have been queued fucks with us.
fdopen doesn't accept "e", it's ignored. Let's not mislead people into
believing that it actually sets O_CLOEXEC.
From `man 3 fdopen`:
> e (since glibc 2.7):
> Open the file with the O_CLOEXEC flag. See open(2) for more information. This flag is ignored for fdopen()
As mentioned by @jlebon in #11131.
This splits out a bunch of functions from fileio.c that have to do with
temporary files. Simply to make the header files a bit shorter, and to
group things more nicely.
No code changes, just some rearranging of source files.
