Commit 003dffde2c ("machined: Move image discovery logic into src/shared,
so that we can make use of it from nspawn") moved some definitions from
machine.h to a new machine-dbus.h, but did not include it in Makefile.am
Tested that `make distcheck` works after this fix.
Even though we use fallocate() it appears that file systems like btrfs
will trigger SIGBUS on certain low-disk-space situation. We should
handle that, hence catch the signal, add it to a list of invalidated
pages, and replace the page with an empty memory area. After each write
check if SIGBUS was triggered, and consider the write invalid if it was.
This should make journald a lot more robust with file systems where
fallocate() is not reliable, for example all CoW file systems
(btrfs...), where changing written data can fail with disk full errors.

systemd.pc contains "libdir" which can be architecture specific. Thus it needs
to be installed into libdir/pkgconfig/ instead of datadir/pkgconfig.
As nothing else is using pkgconfigdata any more, remove it entirely.
Note that udev.pc does not contain architecture specific values and thus can be
kept in /usr/share/pkgconfig/.
When doing "make clean" the unit/machines.target file gets deleted.
This causes a build error later on when trying to rebuild systemd.
V2: The file probably belongs to dist_systemunit_DATA
- Unescape instance name so that we can take almost anything as instance
name.
- Introduce "machines.target" which consists of all enabled nspawns and
can be used to start/stop them altogether
- Look for container directory using -M instead of harcoding the path in
/var/lib/container
After all, pretty much all our tools include it, and it should hence be
shared.
Also move sysfs-show.h from core/ to login/, since it has no point to
exist in core.
I figure "pull-dck" is not a good name, given that one could certainly
read the verb in a way that might be funny for 16year-olds. ;-)
Also, don't hardcode the index URL to use, make it runtime and configure
time configurable instead.
* (potentially) public headers must reside in src/systemd/ (not in
src/libsystemd*)
* some private (not prefixed with sd_) functions moved from sd-lldp.h to
lldp-internal.h
* introduce lldp-util.h for the cleanup macro, as these should not be public
* rename the cleanup macro, we always name them _cleanup_foo_, never
_cleanup_sd_foo_
* mark some function arguments as 'const'
This adds a new bus call to machined that enumerates /var/lib/container
and returns all trees stored in it, distuingishing three types:
- GPT disk images, which are files suffixed with ".gpt"
- directory trees
- btrfs subvolumes
This patch introduces LLDP support to networkd. it implements the
receiver side of the protocol.
The Link Layer Discovery Protocol (LLDP) is an industry-standard,
vendor-neutral method to allow networked devices to advertise
capabilities, identity, and other information onto a LAN. The Layer 2
protocol, detailed in IEEE 802.1AB-2005.LLDP allows network devices
that operate at the lower layers of a protocol stack (such as
Layer 2 bridges and switches) to learn some of the capabilities
and characteristics of LAN devices available to higher
layer protocols.
This adds a simply but powerful tool for downloading container images
from the most popular container solution used today. Use it like
this:
# systemd-import pull-dck mattdm/fedora
# systemd-nspawn -M fedora
This will donwload the layers for "mattdm/fedora", and make them
available locally as /var/lib/container/fedora.
The tool is pretty complete, as long as it's only about pulling down
images, or updating them. Pushing or searching is not supported yet.
This pulls out the hwdb managment from udevadm into an independent tool.
The old code is left in place for backwards compatibility, and easy of
testing, but all documentation is dropped to encourage use of the new
tool instead.
This is libudev-hwdb, but decoupled from libudev and in the libsystemd style.
The core code is unchanged, apart from the following minor changes:
- hwdb.bin located in /**/systemd/hwdb/ take preference over the ones located
in /**/udev/
- properties are stored internally in an OrderedHashmap, rather than a
linked list.
- a new API call allows individual properties to be queried directly, rather
than iterating over them all
- the iteration over properties have been moved inside the library, rather than
exposing a list directly
- the unused 'flags' parameter was dropped
When dbus client connects to systemd-bus-proxyd through
Unix domain socket proxy takes client's smack label and sets for itself.
It is done before and independent of dropping privileges.
The reason of such soluton is fact that tests of access rights
performed by lsm may take place inside kernel, not only
in userspace of recipient of message.
The bus-proxyd needs CAP_MAC_ADMIN to manipulate its label.
In case of systemd running in system mode, CAP_MAC_ADMIN
should be added to CapabilityBoundingSet in service file of bus-proxyd.
In case of systemd running in user mode ('systemd --user')
it can be achieved by addition
Capabilities=cap_mac_admin=i and SecureBits=keep-caps
to user@.service file
and setting cap_mac_admin+ei on bus-proxyd binary.
This is useful inside of containers or local networks to intrdouce a
stable name of the default gateway host (in case of containers usually
the host, in case of LANs usually local router).
The unit file only active the machine-id-commit helper if /etc is mounted
writable and /etc/machine-id is an independant mount point (should be a tmpfs).
