sd_bus_path_{encode,decode}()
The new calls work similarly, but enforce a that a common, fixed bus
path prefix is used.
This follows discussions with Simon McVittie on IRC that it should be a
good idea to make sure that people don't use the escaping applied here
too wildly as anything other than the last label of a bus path.

to device nodes
Since these device nodes will never appear in the container anyway
there's no point in waiting for them.
This makes it easier to boot images generated with general purpose
installers like Anaconda which unconditionally populate /etc/fstab to
boot in containers.

Prepare context_write_data_other() and rename it to
context_write_data_machine_info()

udev_device_get_parent() may return NULL when the device doesn't have a
parent, as is the case with (for example) /sys/devices/virtual/drm/ttm.
Also, log an actual error message instead of "-12 displays connected".

Before it was placed in /dev/disk/by-id, which makes it a bit too much
API. However, it's mostly an implementation detail for now, hence move
it out of the stable block device dir.

We are already assuming the close() will not fail, so make it explicit.

Open all listenerns before loading configuration.

This will be needed for sd-dhcp-server.

If the session already exists then the only way to log it is to set the
debug option of pam_systemd. There are no debug messages in the login
service that permits to log if the session already exists.
So just add it, and while we are it add the "uid" field to the debug
message that indicates that the session was created.

If "systemctl switch-root" is called with a specific "INIT" or
/proc/cmdline contains "init=", then systemd would not serialize
itsself.
Let systemctl check, if the new init is in the standard systemd
installation path and if so, clear the INIT parameter,
to let systemd serialize itsself.

files_same() returns
1, if the files are the same
0, if the files have different inode/dev numbers
errno, for any stat error
|

When we try to send a signal on a connection we didn't hae the time to
process the Disconnected message yet, don't generate multiple warning
messages, but only a single debug message.

/usr/bin/getent instead of in-process
When the container runs a different native architecture than the host we
shouldn't attempt to load the container's NSS modules with the host's
libc. Instead, resolve UID/GID by invoking /usr/bin/getent in the
container. The tool should be fairly universally available and allows us
to do resolving of the UID/GID with the container's libc in a parsable
format.

child after the parent added us to the device cgroup
|
|
We overmount /dev/console with an external pty anyway, hence there's no
point in using the real major/minor when we create the node to
overmount. Instead, use the one of /dev/null now.
This fixes a race against the cgroup device controller setup we are
using. In case /dev/console was create before the cgroup policy was
applied all was good, but if created in the opposite order the mknod()
would fail, since creating /dev/console is not allowed by it. Creating
/dev/null instances is however permitted, and hence use it.

Discoverable Partitions Specification
|
|
|
|
Input devices like rudders or pedals are joystick-like; they don't have
buttons, but axes like RX, THROTTLE, or RUDDER. These don't interfere with
other device types with absolute axes (touch screens, touchpads, and
accelerometers), so it's fairly safe to mark them as ID_INPUT_JOYSTICK and thus
hand out dynamic ACLs to the user.

Since the index is already post-incremented when the array is appended
to, this assertion can be wrongly reached when the array is at capacity
(with the NULL terminator). The bug is reproducible on shutdown with
the following settings in /etc/systemd/system.conf:
LogTarget=journal-or-kmsg
LogColor=yes
LogLocation=yes

Fixup for 76800848f281c3 'networkd: link - degrade failed UP to warning'.
|
|
For large values of item->size, the 'part' pointer can wrap around,
which results in an illegal pointer, but currently passes the for-loop
condition.

interested in
Instead of iterating through the list of partitions and probing them all
with blkid, simply probe the partition table and use that information to
only probe the partitions we care for.

Something else may still bring the link up, so don't enter failed state prematurely.

Bring some arrays that are used for DEFINE_STRING_TABLE_LOOKUP() in the
same order than the enums they reference.
Also, pass the corresponding _MAX value to the array initalizer where
appropriate.

Activator connections may upload policy when registering to the bus.
This patch contains code to translate between BusNamePolicy objects and
the kdbus specific items.
|
|
Bring kdbus.h in sync with recent policy related changes. Most notably,
KDBUS_MAKE_POLICY_OPEN is now gone. The rest doesn't matter for systemd
at this point, as the policy functionality was not yet used.

There are three directives to specify bus name polices in .busname
files:
* AllowUser [username] [access]
* AllowGroup [groupname] [access]
* AllowWorld [access]
Where [access] is one of
* 'see': The user/group/world is allowed to see a name on the bus
* 'talk': The user/group/world is allowed to talk to a name
* 'own': The user/group/world is allowed to own a name

This patch introduces reading ethernet address and IPV4/IPv6
as well which is based on table based look up.
[tomegun: rename read_ether() to read_ether_addr() to match the append function.]

When the manager receives a SIGUSR2 signal, it opens a memory stream
with open_memstream(), uses the returned file handle for logging, and
dumps the logged content with log_dump().
However, the char* buffer is only safe to use after the file handle has
been flushed with fflush, as the man pages states:
When the stream is closed (fclose(3)) or flushed (fflush(3)), the
locations pointed to by ptr and sizeloc are updated to contain,
respectively, a pointer to the buffer and the current size of the
buffer.
These values remain valid only as long as the caller performs no
further output on the stream. If further output is performed, then the
stream must again be flushed before trying to access these variables.
Without that call, dump remains NULL and the daemon crashes in
log_dump().

When a busname unit enters BUSNAME_FAILURE_SERVICE_FAILED_PERMANENT, the
serialization will not be able to look up the result as string via
busname_result_to_string(). This leads to an assertion trap during
daemon-reexec.

When run in an initrd and no root= argument is set (or is set to
root=gpt-auto) we will automatically look for the root partition on the
same disk the EFI ESP is located on.
Since we look for swap, /home and /srv on the disk the root partition is
located on, we hence have a fully discoverable chain:
Firmware discovers the EFI ESP partition → the initrd discovers the
root partition → the host OS discovers swap, /home, and /srv.
Note that this requires an EFI boot loader that sets the
LoaderDevicePartUUID EFI variable, such as Gummiboot.
