Environment=ONE='one' "TWO='two two' too" THREE=
ExecStart=/bin/python3 -c 'import sys;print(sys.argv)' $ONE $TWO $THREE
-* When systemctl --host is used, underlying ssh connection can remain open.
- bus_close does not kill children?
-
External:
* Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
* wiki: update journal format documentation for lz4 additions
-* When lz4 gets an API for lz4 command output, make use of it to
- compress coredumps in a way compatible with /usr/bin/lz4.
+Janitorial Clean-ups:
+
+* Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
Features:
-* PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
+* sort generated hwdb files alphabetically when we import them, so that git
+ diffs remain minimal (in particular: the OUI databases we import are not
+ sorted, and not stable)
-* nspawn should send out sd_notify("WATCHDOG=1") messages
+* set SystemCallArchitectures=native on all our services
-* nspawn should optionally support receiving WATCHDOG=1 messages from its payload PID 1...
+* maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
+ the sd-journal logging socket, and, if the timeout is set to 0, sets
+ O_NONBLOCK on it. That way people can control if and when to block for
+ logging.
-* introduce "machinectl shell" that is like systemd-run -M foo /bin/bash -t but also adds PAMName=login
+* tighten sd_notify() MAINPID= checks a bit: don't accept foreign PIDs (i.e.
+ PIDs not managed by the service manager)
-* allow loging into host with "machinectl login".
+* journald: when we recv a log datagram via the native or syslog transports,
+ search for the PID in the active stream connections, and let's make sure to
+ always process the datagrams before the streams. Then, cache client metadata
+ per stream in the stream object. This way we can somewhat fix the race with
+ quickly exiting processes which log as long as they had their own stream
+ connection...
-* consider throwing a warning if a service declares it wants to be "Before=" a .device unit.
+* hostnamed: populate form factor data from a new hwdb database, so that old
+ yogas can be recognized as "convertible" too, even if they predate the DMI
+ "convertible" form factor
-* "systemctl edit" should know a mode to create a new unit file
+* Maybe add a small tool invoked early at boot, that adds in or resizes
+ partitions automatically, to be used when the media used is actually larger
+ than the image written onto it is.
-* there's probably something wrong with having user mounts below /sys,
- as we have for debugfs. for exmaple, src/core/mount.c handles mounts
- prefixed with /sys generally special.
- http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
+* Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
+ after all. Be strict however, only support the equivalent of nspawn's
+ --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
+ as MAINPID.
-* Add PassEnvironment= setting to service units, to import select env vars from PID 1 into the service env block
+* change the dependency Set* objects in Unit structures to become Hashmap*, and
+ then store a bit mask who created a specific dependency: the source unit via
+ fragment configuration, the destination unit via fragment configuration, or
+ the source unit via udev rules (in case of .device units), or any combination
+ thereof. This information can then be used to flush out old udev-created
+ dependencies when the udev properties change, and eventually to implement a
+ "systemctl refresh" operation for reloading the configuration of individual
+ units without reloading the whole set.
-* nspawn: fix logic always print a final newline on output.
- https://github.com/systemd/systemd/pull/272#issuecomment-113153176
+* Add ExecMonitor= setting. May be used multiple times. Forks off a process in
+ the service cgroup, which is supposed to monitor the service, and when it
+ exits the service is considered failed by its monitor.
-* make nspawn's --network-veth switch more powerful:
- http://lists.freedesktop.org/archives/systemd-devel/2015-June/033121.html
+* track the per-service PAM process properly (i.e. as an additional control
+ process), so that it may be queried on the bus and everything.
-* man: document that unless you use StandardError=null the shell >/dev/stderr won't work in shell scripts in services
+* add a new "debug" job mode, that is propagated to unit_start() and for
+ services results in two things: we raise SIGSTOP right before invoking
+ execve() and turn off watchdog support. Then, use that to implement
+ "systemd-gdb" for attaching to the start-up of any system service in its
+ natural habitat.
-* man: clarify that "machinectl show" shows different information than "machinectl status" (no cgroup tree, no IP addresses, ...)
+* replace all canonicalize_file_name() invocations by chase_symlinks(), in
+ particulr those where a rootdir is relevant.
-* "systemctl daemon-reload" should result in /etc/systemd/system.conf being reloaded by systemd
+* maybe introduce gpt auto discovery for /var/tmp?
-* install: include generator dirs in unit file search paths
+* set ProtectSystem=strict for all our usual services.
-* stop using off_t, it's a crazy type. Use uint64_t instead.
+* fix PrivateNetwork= so that we fall back gracefully on kernels lacking
+ namespacing support (similar for the other namespacing options)
-* logind: follow PropertiesChanged state more closely, to deal with quick logouts and relogins
+* maybe add gpt-partition-based user management: each user gets his own
+ LUKS-encrypted GPT partition with a new GPT type. A small nss module
+ enumerates users via udev partition enumeration. UIDs are assigned in a fixed
+ way: the partition index is added as offset to some fixed base uid. User name
+ is stored in GPT partition name. A PAM module authenticates the user via the
+ LUKS partition password. Benefits: strong per-user security, compatibility
+ with stateless/read-only/verity-enabled root. (other idea: do this based on
+ loopback files in /home, without GPT involvement)
-* change to KillMode=mixed by default
+* gpt-auto logic: introduce support for discovering /var matching an image. For
+ that, use a partition type UUID that is hashed from the OS name (as encoded
+ in /etc/os-release), the architecture, and 4 new bits from the gpt flags
+ field of the root partition. This way can easily support multiple OS
+ installations on the same GPT partition table, without problems with
+ unmatched /var partitions.
-* introduce argv0contains=
+* gpt-auto logic: related to the above, maybe support a "secondary" root
+ partition, that is mounted to / and is writable, and where the actual root's
+ /usr is mounted into.
-* invent a better systemd-run scheme for naming scopes, that works with remoting
+* machined: add apis to query /etc/machine-info data of a container
-* add journalctl -H that talks via ssh to a remote peer and passes through binary logs data
+* .mount and .swap units: add Format=yes|no option that formats the partition before mounting/enabling it, implicitly
-* change journalctl -M to acquire fd to journal directory via machined, and then operate on that via openat() instead of absolute paths
+* gpt-auto logic: support encrypted swap, add kernel cmdline option to force it, and honour a gpt bit about it, plus maybe a configuration file
-* add a version of --merge which also merges /var/log/journal/remote
+* drop nss-myhostname in favour of nss-resolve?
-* log accumulated resource usage after each service invocation
+* drop internal dlopen() based nss-dns fallback in nss-resolve, and rely on the
+ external nsswitch.conf based one
-* nspawn: a nice way to boot up without machine id set, so that it is set at boot automatically for supporting --ephemeral. Maybe hash the host machine id together with the machine name to generate the machine id for the container
+* add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
+ then use that for the setting used in user@.service. It should be understood
+ relative to the configured default value.
-* logind: rename session scope so that it includes the UID. THat way
- the session scope can be arranged freely in slices and we don't have
- make assumptions about their slice anymore.
+* on cgroupsv2 add DelegateControllers=, to pick the precise cgroup controllers to delegate
-* journalctl: -m should access container journals directly by enumerating them via machined, and also watch containers coming and going. Benefit: nspawn --ephemeral would start working nicely with the journal.
+* in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
-* nspawn: don't copy /etc/resolv.conf from host into container unless we are in shared-network mode
+* enable LockMLOCK to take a percentage value relative to physical memory
-* nspawn: optionally automatically add FORWARD rules to iptables whenever nspawn is running, remove them when shut down.
+* switch to ProtectSystem=strict for all our long-running services where that's possible
-* importd: generate a nice warning if mkfs.btrfs is missing
+* Permit masking specific netlink APIs with RestrictAddressFamily=
-* nspawn: add a logic for cleaning up read-only, hidden container images in /var/lib/machines that are not ancestors of any non-hidden containers
+* nspawn: start UID allocation loop from hash of container name
-* nspawn: Improve error message when --bind= is used on a non-existing source directory
+* nspawn: support that /proc, /sys/, /dev are pre-mounted
-* nspawn: maybe make copying of /etc/resolv.conf optional, and skip it if --read-only is used
+* define gpt header bits to select volatility mode
-* man: document how update dkr images works with machinectl
- http://lists.freedesktop.org/archives/systemd-devel/2015-February/028630.html
+* ProtectKernelLogs= (drops CAP_SYSLOG, add seccomp for syslog() syscall, and DeviceAllow to /dev/kmsg) in service files
-* nspawn: as soon as networkd has a bus interface, hook up --network-interface=, --network-bridge= with networkd, to trigger netdev creation should an interface be missing
+* ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
-* rework C11 utf8.[ch] to use char32_t instead of uint32_t when referring
- to unicode chars, to make things more expressive.
+* ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
-* "machinectl migrate" or similar to copy a container from or to a
- difference host, via ssh
+* ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
-* tmpfiles: creating new directories/subvolumes/fifos/device nodes
- should not follow symlinks. None of the other adjustment or creation
- calls follow symlinks.
+* ProtectKeyRing= to take keyring calls away
-* fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
+* RemoveKeyRing= to remove all keyring entries of the specified user
-* docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
+* ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
+ on PID 1 with the relevant signals, and makes relevant files in /sys and
+ /proc (such as the sysrq stuff) unavailable
-* mounting and unmounting mount points manually with different source
- devices will result in collected collected on all devices used.
- http://lists.freedesktop.org/archives/systemd-devel/2015-April/030225.html
+* DeviceAllow= should also generate seccomp filters for mknod()
-* add a job mode that will fail if a transaction would mean stopping
- running units. Use this in timedated to manage the NTP service
- state.
- http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
+* Add DataDirectory=, CacheDirectory= and LogDirectory= to match
+ RuntimeDirectory=, and create it as necessary when starting a service, owned by the right user.
-* Maybe add support for the equivalent of "ethtool advertise" to .link files?
- http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html
+* make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
-* .timer units should optionally support CLOCK_BOOTTIME in addition to CLOCK_MONOTONIC
+* journalctl: make sure -f ends when the container indicated by -M terminates
-* create a btrfs qgroup for /var/lib/machines, and add all container
- subvolumes we create to it.
+* mount: automatically search for "main" partition of an image has multiple
+ partitions
-* When logging about multiple units (stopping BoundTo units, conflicts, etc.),
- log both units as UNIT=, so that journalctl -u triggers on both.
+* expose the "privileged" flag of ExecCommand on the bus, and open it up to
+ transient units
-* to allow "linking" of nspawn containers, extend --network-bridge= so
- that it can dynamically create bridge interfaces that are refcounted
- by the containers on them. For each group of containers to link together
+* in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
+ find a way to map the User=/Group= of the service to the right name. This way
+ a user/group for a service only has to exist on the host for the right
+ mapping to work.
-* journalctl --verify: don't show files that are currently being
- written to as FAIL, but instead show that their are being written
- to.
+* allow attaching additional journald log fields to cgroups
-* assign MESSAGE_ID to log messages about failed services
+* add bus API for creating unit files in /etc, reusing the code for transient units
-* coredump: make the handler check /proc/$PID/rlimits for RLIMIT_CORE,
- and supress coredump if turned off. Then change RLIMIT_CORE to
- infinity by default for all services. This then allows per-service
- control of coredumping.
+* add bus API to remove unit files from /etc
-* generate better errors when people try to set transient properties
- that are not supported...
- http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
+* add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
-* Introduce $LISTEN_NAMES to complement $LISTEN_FDS, containing a
- colon separated list of identifiers for the fds passed.
+* rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
+ kernel doesn't support linkat() that replaces existing files, currently)
-* maybe introduce WantsMountsFor=? Usecase:
- http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
+* check if DeviceAllow= should split first, resolve specifiers later
-* rework kexec logic to use new kexec_file_load() syscall, so that we
- don't have to call kexec tool anymore.
+* transient units: don't bother with actually setting unit properties, we
+ reload the unit file anyway
-* The udev blkid built-in should expose a property that reflects
- whether media was sensed in USB CF/SD card readers. This should then
- be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
- picked up by systemd unless they contain a medium. This would mirror
- the behaviour we already have for CD drives.
+* journald: sigbus API via a signal-handler safe function that people may call
+ from the SIGBUS handler
-* nspawn: emulate /dev/kmsg using CUSE and turn off the syslog syscall
- with seccomp. That should provide us with a useful log buffer that
- systemd can log to during early boot, and disconnect container logs
- from the kernel's logs.
+* optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
-* networkd/udev: implement SR_IOV configuration in .link files:
- http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
+* resolved: when routing queries, make sure only look for the *longest* suffix...
-* When RLIMIT_NPROC is set from a unit file it currently always is set
- for root, not for the user set in User=, which makes it
- useless. After fixing this, set RLIMIT_NPROC for
- systemd-journal-xyz, and all other of our services that run under
- their own user ids, and use User= (but only in a world where userns
- is ubiquitous since otherwise we cannot invoke those daemons on the
- host AND in a container anymore). Also, if LimitNPROC= is used
- without User= we should warn and refuse operation.
+* delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
+ in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
-* logind: maybe allow configuration of the StopTimeout for session scopes
+* cache sd_event_now() result from before the first iteration...
-* Set NoNewPrivileges= on all of our own services, where that makes sense
+* add systemctl stop --job-mode=triggering that follows TRIGGERED_BY deps and adds them to the same transaction
-* Rework systemctl's GetAll property parsing to use the generic bus_map_all_properties() API
+* PID1: find a way how we can reload unit file configuration for
+ specific units only, without reloading the whole of systemd
+
+* add an explicit parser for LimitRTPRIO= that verifies
+ the specified range and generates sane error messages for incorrect
+ specifications.
+
+* do something about "/control" subcgroups in the unified cgroup hierarchy
+
+* when we detect that there are waiting jobs but no running jobs, do something
+
+* push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy)
-* rework journald sigbus stuff to use mutex
+* PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
-* import-dkr: support tarsum checksum verification, if it becomes reality one day...
+* there's probably something wrong with having user mounts below /sys,
+ as we have for debugfs. for exmaple, src/core/mount.c handles mounts
+ prefixed with /sys generally special.
+ http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
-* import-dkr: convert json bits to nspawn configuration
+* man: document that unless you use StandardError=null the shell >/dev/stderr won't work in shell scripts in services
-* core/cgroup: support net_cls modules, and support automatically allocating class ids, then add support for making firewall changes depending on it, to implement a per-service firewall
+* fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
-* introduce systemd-nspawn-ephemeral@.service, and hook it into "machinectl start" with a new --ephemeral switch
+* docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
-* "machinectl status" should also show internal logs of the container in question
+* mounting and unmounting mount points manually with different source
+ devices will result in collected on all devices used.
+ http://lists.freedesktop.org/archives/systemd-devel/2015-April/030225.html
-* "machinectl list-images" should show os-release data, as well as machine-info data (including deployment level)
+* add a job mode that will fail if a transaction would mean stopping
+ running units. Use this in timedated to manage the NTP service
+ state.
+ http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
-* nspawn: when start a container "foobar" look for its configuration in a file "foobar.nspawn" in /etc/systemd/nspawn/ as well as next to the actualy directory or image to boot
+* Maybe add support for the equivalent of "ethtool advertise" to .link files?
+ http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html
-* Port various tools to make use of verbs.[ch], where applicable
+* The udev blkid built-in should expose a property that reflects
+ whether media was sensed in USB CF/SD card readers. This should then
+ be used to control SYSTEMD_READY=1/0 so that USB card readers aren't

-* "machinectl history"
+* networkd/udev: implement SR_IOV configuration in .link files:

-* "machinectl diff"
+* Rework systemctl's GetAll property parsing to use the generic bus_map_all_properties() API
-* "machinectl commit" that takes a writable snapshot of a tree, invokes a shell in it, and marks it read-only after use
+* implement a per-service firewall based on net_cls
-* systemd-nspawn -x should support ephemeral instances of gpt images
+* Port various tools to make use of verbs.[ch], where applicable: busctl,
+ coredumpctl, hostnamectl, localectl, systemd-analyze, timedatectl
* hostnamectl: show root image uuid
* Find a solution for SMACK capabilities stuff:
http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
-* port libmount hookup to use API's own inotify interface, as soon as that is table in libmount
-
* "systemctl preset-all" should probably order the unit files it
operates on lexicographically before starting to work, in order to
ensure deterministic behaviour if two unit files conflict (like DMs
do, for example)
-* resolved should optionally register additional per-interface LLMNR
- names, so that for the container case we can establish the same name
- (maybe "host") for referencing the server, everywhere.
-
-* systemd-journal-upload (or a new, related tool): allow pushing out
- journal messages onto the network in BSD syslog protocol,
- continuously. Default to some link-local IP mcast group, to make this
- useful as a one-stop debugging tool.
-
* synchronize console access with BSD locks:
http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
-* as soon as we have kdbus, and sender timestamps, revisit coalescing multiple parallel daemon reloads:
+* as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
-* the install state probably shouldn't get confused by generated units, think dbus1/kdbus compat!
-
* in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
* figure out when we can use the coarse timers
-* sd-resolve: drop res_query wrapping, people should call via the bus to resolved instead
-
* add "systemctl start -v foobar.service" that shows logs of a service
while the start command runs. This is non-trivial to do without
races though, since we should flush out all journal messages before
* firstboot: make it useful to be run immediately after yum --installroot to set up a machine. (most specifically, make --copy-root-password work even if /etc/passwd already exists
-* timesyncd + resolved: add ugly bus calls to set NTP and DNS servers per-interface, for usage by NM
-
-* add infrastructure to allocate dynamic/transient users and UID ranges, for use in user-namespaced containers, per-seat gdm login screens and gdm guest sessions
-
-* machined: add an API so that libvirt-lxc can inform us about network interfaces being removed or added to an existing machine
-
* maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
-* code cleanup: retire FOREACH_WORD_QUOTED, port to extract_first_word() loops instead
-
* introduce systemd-timesync-wait.service or so to sync on an NTP fix?
* systemd --user should issue sd_notify() upon reaching basic.target, not on becoming idle
* consider showing the unit names during boot up in the status output, not just the unit descriptions
-* dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
-
* maybe allow timer units with an empty Units= setting, so that they
can be used for resuming the system but nothing else.
* maybe provide an API to allow migration of foreign PIDs into existing scopes.
-* maybe support a new very "soft" reboot mode, that simply kills all processes, disassembles everything, flushes /run and sysvipc, and then reexecs systemd again
-
-* man: document that corrupted journal files is nothing to act on
-
* man: maybe use the word "inspect" rather than "introspect"?
-* "machinectl list" should probably show columns for OS version and IP addresses
-
* systemctl: if some operation fails, show log output?
-* systemctl edit:
-- allow creation of units from scratch
-- use equvalent of cat() to insert existing config as a comment, prepended with #.
+* systemctl edit: use equvalent of cat() to insert existing config as a comment, prepended with #.
Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
-* refcounting in sd-resolve is borked
+* exponential backoff in timesyncd when we cannot reach a server
-* exponential backoff in timesyncd and resolved when we cannot reach a server
-
-* extract_many_words() should probably be used by a lot of code that
- currently uses FOREACH_WORD and friends. For example, most conf
- parsing callbacks should use it.
+* timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
* merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
* add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
(throughout the codebase, not only PID1)
-* networkd:
- - make DHCP server IP range configurable, including only with a single IP address
- - dhcp server: try to assign stable IP addresses based on client's MAC address
- - add LLDP client side support
- - the DHCP lease data (such as NTP/DNS) is still made available when
- a carrier is lost on a link. It should be removed instantly.
- - expose in the API the following bits:
- - option 15, domain name and/or option 119, search list
- - option 12, host name and/or option 81, fqdn
- - option 100, 101, timezone
- - option 123, 144, geolocation
- - option 252, configure http proxy (PAC/wpad)
- - networkd's dhcp server should transparently pass on the DNS and
- NTP server list it got from user configuration and its dhcp client
- to clients. It should also pass on its own timezone information.
- - provide a way to define a per-network interface default metric value
- for all routes to it. possibly a second default for DHCP routes.
- - allow Name= to be specified repeatedly in the [Match] section. Maybe also
- support Name=foo*|bar*|baz ?
- - duplicate address check for static IPs (like ARPCHECK in network-scripts)
- - allow DUID/IAID to be customized, see issue #394.
-
* resolved:
- - put networkd events and rtnl events at a higher priority, so that
- we always process them before we process client requests
- - DNSSEC
- - add display of private key types (http://tools.ietf.org/html/rfc4034#appendix-A.1.1)?
- - DNS
- - search paths
- mDNS/DNS-SD
+ - service registration
+ - service/domain/types browsing
- avahi compat
- DNS-SD service registration from socket units
- - edns0
- - dname: Not necessary for plain DNS as synthesized cname is handed out instead if we do not
- announce dname support. However, for DNSSEC it is necessary as the synthesized cname
- will not be signed.
- - cname on PTR (?)
+ - resolved should optionally register additional per-interface LLMNR
+ names, so that for the container case we can establish the same name
+ (maybe "host") for referencing the server, everywhere.
+ - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
+ - hook up resolved with machined-based address resolution
-* Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
+* refcounting in sd-resolve is borked
* Add a new verb "systemctl top"
* support empty /etc boots nicely:
- nspawn/gpt-generator: introduce new gpt partition type for /usr
- - fstab-generator: support systemd.volatile=yes|no|state on the kernel cmdline, too, similar to nspawn's --volatile=
* generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
-* timer units: actually add extra delays to timer units with high AccuracySec values, don't start them already when we are awake...
-
* a way for container managers to turn off getty starting via $container_headless= or so...
* figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
* For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
they run added to the initial transaction and thus confuse Type=idle.
-* Run most system services with cgroupfs read-only and procfs with a more secure mode (doesn't work, since the hidepid= option is per-pid-namespace, not per-mount)
-
-* sd-event: generate a failure of a default event loop is executed out-of-thread
-
* add bus api to query unit file's X fields.
-* consider adding RuntimeDirectoryUser= + RuntimeDirectoryGroup=
-
-* sd-event: define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
-
* gpt-auto-generator:
- - Support LUKS for root devices
- Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
- Make /home automount rather than mount?
CAP_NET_ADMIN is set, more than the loopback device is defined, even
when it is otherwise off
-* MessageQueueMessageSize= and RLimitFSIZE= (and suchlike) should use parse_iec_size().
-
-* "busctl status" works only as root on dbus1, since we cannot read
- /proc/$PID/exe
+* MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
* implement Distribute= in socket units to allow running multiple
service instances processing the listening socket, and open this up
and passes this back to PID1 via SCM_RIGHTS. This also could be used
to allow Chown/chgrp on sockets without requiring NSS in PID 1.
-* New service property: maximum CPU and wallclock runtime for a service
-
* introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
$UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
should SIGSTOP all unit processes in a loop until all processes of
* when we detect low battery and no AC on boot, show pretty splash and refuse boot
-* machined, localed: when we try to kill an empty cgroup, generate an ESRCH error over the bus
-
* libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
* be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
-* unify dispatch table in systemctl_main() and friends
-
* rfkill,backlight: we probably should run the load tools inside of the udev rules so that the state is properly initialized by the time other software sees it
* After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
error. Currently, we just ignore it and read the unit from the search
path anyway.
-* refuse boot if /etc/os-release is missing or /etc/machine-id cannot be set up
-
-* btrfs raid assembly: some .device jobs stay stuck in the queue
-
-* make sure gdm does not use multi-user-x but the new default X configuration file, and then remove multi-user-x from systemd
+* refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
* man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
* sd-bus:
- EBADSLT handling
- - change argv list matching logic
- GetAllProperties() on a non-existing object does not result in a failure currently
- kdbus: process fd=-1 for incoming msgs
- port to sd-resolve for connecting to TCP dbus servers
- path escaping
- update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
- test bloom filter generation indexes
- - bus-proxy: when passing messages from kdbus, make sure we properly
- handle the case where a large number of fds is appended that we
- cannot pass into sendmsg() of the AF_UNIX sokcet (which only accepts
- 253 messages)
- kdbus: introduce a concept of "send-only" connections
- kdbus: add counter for refused unicast messages that is passed out via the RECV ioctl. SImilar to the counter for dropped multicast messages we already have.
* sd-event
- allow multiple signal handlers per signal?
- document chaining of signal handler for SIGCHLD and child handlers
-
-* in the final killing spree, detect processes from the root directory, and
- complain loudly if they have argv[0][0] == '@' set.

+ - maybe add support for inotify events
* investigate endianness issues of UUID vs. GUID
* systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
-* journal-or-kmsg is currently broken? See reverted commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.

-* remove any syslog support from log.c -- we probably cannot do this before split-off udev is gone for good
+* remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good

* think about window-manager-run-as-user-service problem: exit 0 → activate shutdown.target; exit != 0 → restart service
* merge unit_kill_common() and unit_kill_context()

-* fstab: add new mount option x-systemd-after=/foobar/waldo to allow manual dependencies to other mount points
- https://bugzilla.redhat.com/show_bug.cgi?id=812826
-
* print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
* mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
probably reduce the capability set it retains substantially.
(we need CAP_SYS_ADMIN for drmSetMaster(), so maybe not worth it)
- expose orientation sensors and tablet mode through logind
+ - maybe allow configuration of the StopTimeout for session scopes
+ - rename session scope so that it includes the UID. THat way
+ the session scope can be arranged freely in slices and we don't have
+ make assumptions about their slice anymore.
+ - follow PropertiesChanged state more closely, to deal with quick logouts and
+ relogins
* exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
- add API to close/reopen/get fd for journal client fd in libsystemd-journal.
- fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
- declare the local journal protocol stable in the wiki interface chart
- - journal: reuse XZ context
- sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
- journald: when dropping msgs due to ratelimit make sure to write
"dropped %u messages" not only when we are about to print the next
message that works, but alraedy after a short tiemout
- check if we can make journalctl by default use --follow mode inside of less if called without args?
- maybe add API to send pairs of iovecs via sd_journal_send
- - journal: when writing journal auto-rotate if time jumps backwards
- journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
- journactl: support negative filtering, i.e. FOOBAR!="waldo",
and !FOOBAR for events without FOOBAR.
lazily. Encode just enough information in the file name, so that we
do not have to open it to know that it is not interesting for us, for
the most common operations.
+ - journal-or-kmsg is currently broken? See reverted
+ commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
+ - man: document that corrupted journal files is nothing to act on
+ - rework journald sigbus stuff to use mutex
+ - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
+ services that run under their own user ids, and use User= (but only
+ in a world where userns is ubiquitous since otherwise we cannot
+ invoke those daemons on the host AND in a container anymore). Also,
+ if LimitNPROC= is used without User= we should warn and refuse
+ operation.
+ - journalctl --verify: don't show files that are currently being
+ written to as FAIL, but instead show that their are being written to.
+ - add journalctl -H that talks via ssh to a remote peer and passes through
+ binary logs data
+ - add a version of --merge which also merges /var/log/journal/remote
+ - log accumulated resource usage after each service invocation
+ - journalctl: -m should access container journals directly by enumerating
+ them via machined, and also watch containers coming and going.
+ Benefit: nspawn --ephemeral would start working nicely with the journal.
+ - assign MESSAGE_ID to log messages about failed services
* document:
- document that deps in [Unit] sections ignore Alias= fields in
- document systemd-journal-flush.service properly
- documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
- man: document the very specific env the shutdown drop-in tools live in
- - man: extend runlevel(8) to mention that runlevels suck, and are dead. Maybe add runlevel(7) with a note about that too
- man: add more examples to man pages
- man: maybe sort directives in man pages, and take sections from --help and apply them to man too
* systemctl:
- - systemctl list-jobs - show dependencies
- add systemctl switch to dump transaction without executing it
- Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
- "systemctl disable" on a static unit prints no message and does
- add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
- systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
- systemctl: "Journal has been rotated since unit was started." message is misleading
- - support "systemctl stop foobar@.service" to stop all units matching a certain template
- - Something is wrong with symlink handling of "autovt@.service" in "systemctl list-unit-files"
- better error message if you run systemctl without systemd running
- - systemctl status output should should include list of triggering units and their status
+ - systemctl status output should include list of triggering units and their status
* unit install:
- "systemctl mask" should find all names by which a unit is accessible
(i.e. by scanning for symlinks to it) and link them all to /dev/null
- - systemctl list-unit-files should list generated files (and probably with a new state "generated" for them, or so)
* timer units:
- timer units should get the ability to trigger when:
o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
o DST changes
- - Support 2012-02~4 as syntax for specifying the fourth to last day of the month.
- - calendarspec: support value ranges with ".." notation. Example: 2013-4..8-1
- - when parsing calendar timestamps support the UTC timezone (even if we will not support arbitrary timezone specs, support UTC itself certainly makes sense), also support syntaxes such as +0200
- Modulate timer frequency based on battery state
* add libsystemd-password or so to query passwords during boot using the password agent logic
-* If we show an error about a unit (such as not showing up) and it has no Description string, then show a description string generated form the reverse of unit_name_mangle().
-
* clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
* on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
-* make repeated alt-ctrl-del presses printing a dump, or even force a reboot without
- waiting for the timeout
+* make repeated alt-ctrl-del presses printing a dump
* hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
* currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
* nspawn:
- - refuses to boot containers without /etc/machine-id (OK?), and with empty /etc/machine-id (not OK).
+ - emulate /dev/kmsg using CUSE and turn off the syslog syscall
+ with seccomp. That should provide us with a useful log buffer that
+ systemd can log to during early boot, and disconnect container logs
+ from the kernel's logs.
+ - as soon as networkd has a bus interface, hook up --network-interface=,
+ --network-bridge= with networkd, to trigger netdev creation should an
+ interface be missing
+ - a nice way to boot up without machine id set, so that it is set at boot
+ automatically for supporting --ephemeral. Maybe hash the host machine id
+ together with the machine name to generate the machine id for the container
+ - fix logic always print a final newline on output.
+ https://github.com/systemd/systemd/pull/272#issuecomment-113153176
+ - should optionally support receiving WATCHDOG=1 messages from its payload
+ PID 1...
+ - should send out sd_notify("WATCHDOG=1") messages
+ - optionally automatically add FORWARD rules to iptables whenever nspawn is
+ running, remove them when shut down.
+ - Improve error message when --bind= is used on a non-existing source
+ directory
+ - maybe make copying of /etc/resolv.conf optional, and skip it if --read-only
+ is used
+
+* dissect
+ - refuse mounting over a mount point
+ - automatically discover .roothash files in dissect, similarly to nspawn
+
+* machined:
+ - add an API so that libvirt-lxc can inform us about network interfaces being
+ removed or added to an existing machine
+ - "machinectl migrate" or similar to copy a container from or to a
+ difference host, via ssh
+ - introduce systemd-nspawn-ephemeral@.service, and hook it into
+ "machinectl start" with a new --ephemeral switch
+ - "machinectl status" should also show internal logs of the container in
+ question
+ - "machinectl list-images" should show os-release data, as well as
+ machine-info data (including deployment level)
+ - "machinectl history"
+ - "machinectl diff"
+ - "machinectl commit" that takes a writable snapshot of a tree, invokes a
+ shell in it, and marks it read-only after use
+
+* importd:
+ - generate a nice warning if mkfs.btrfs is missing
* cryptsetup:
- cryptsetup-generator: allow specification of passwords in crypttab itself
* hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
