Features:
+* ProtectKernelLogs= (drops CAP_SYSLOG, add seccomp for syslog() syscall, and DeviceAllow to /dev/kmsg) in service files
+
+* ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
+
+* ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
+
+* ProtectDevices= should also take iopl/ioperm/pciaccess away
+
+* ProtectKeyRing= to take keyring calls away
+
+* PrivateUsers= which maps the all user ids except root and the one specified
+ in User= to nobody
+
+* Add AllocateUser= for allowing dynamic user ids per-service
+
+* Add DataDirectory=, CacheDirectory= and LogDirectory= to match
+ RuntimeDirectory=, and create it as necessary when starting a service, owned by the right user.
+
+* Add BindDirectory= for allowing arbitrary, private bind mounts for services
+
+* Beef up RootDirectory= to use namespacing/bind mounts as soon as fs
+ namespaces are enabled by the service
+
+* Add RootImage= for mounting a disk image or file as root directory
+
+* RestrictNamespaces= or so in services (taking away the ability to create namespaces, with setns, unshare, clone)
+
+* nspawn: make /proc/sys/net writable?
+
+* make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
+
+* journalctl: make sure -f ends when the container indicated by -M terminates
+
+* expose the "privileged" flag of ExecCommand on the bus, and open it up to
+ transient units
+
+* allow attaching additional journald log fields to cgroups
+
+* rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
+ kernel doesn't support linkat() that replaces existing files, currently)
+
+* check if DeviceAllow= should split first, resolve specifiers later
+
+* transient units: don't bother with actually setting unit properties, we
+ reload the unit file anyway
+
+* journald: sigbus API via a signal-handler safe function that people may call
+ from the SIGBUS handler
+
+* when using UTF8, ellipsize with "…" rather than "...", so that we can show more contents before truncating
+
+* move specifier expansion from service_spawn() into load-fragment.c
+
+* optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
+
+* resolved: when routing queries, make sure only look for the *longest* suffix...
+
+* 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
+
+* cache sd_event_now() result from before the first iteration...
+
+* add systemctl stop --job-mode=triggering that follows TRIGGERED_BY deps and adds them to the same transaction
+
+* Maybe add a way how users can "pin" units into memory, so that they are not subject to automatic GC?
+
* 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 LimitNICE= and LimitRTPRIO= that verifies
+* add an explicit parser for LimitRTPRIO= that verifies
the specified range and generates sane error messages for incorrect
- specifications. Also, for LimitNICE= maybe introduce a syntax such
- as "+5" or "-7" in order to make the limits more readable as they
- are otherwise shifted by 20.
+ specifications.
* do something about "/control" subcgroups in the unified cgroup hierarchy
* push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy)
-* add a new command "systemctl revert" or so, that removes all dropin
- snippets in /run and /etc, and all unit files with counterparts in
- /usr, and thus undoes what "systemctl set-property" and "systemctl
- edit" create. Maybe even add "systemctl revert -a" to do this for
- all units.
-
* PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
* consider throwing a warning if a service declares it wants to be "Before=" a .device unit.
-* "systemctl edit" should know a mode to create a new unit file
-
* 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.
* man: document that unless you use StandardError=null the shell >/dev/stderr won't work in shell scripts in services
-* "systemctl daemon-reload" should result in /etc/systemd/system.conf being reloaded by systemd
-
-* install: include generator dirs in unit file search paths
-
-* invent a better systemd-run scheme for naming scopes, that works with remoting
-
-* rework C11 utf8.[ch] to use char32_t instead of uint32_t when referring
- to unicode chars, to make things more expressive.
-
* fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
* docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
* mounting and unmounting mount points manually with different source
- devices will result in collected collected on all devices used.
+ devices will result in collected on all devices used.
http://lists.freedesktop.org/archives/systemd-devel/2015-April/030225.html
* add a job mode that will fail if a transaction would mean stopping
* Rework systemctl's GetAll property parsing to use the generic bus_map_all_properties() API
-* 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
+* implement a per-service firewall based on net_cls
-* Port various tools to make use of verbs.[ch], where applicable
+* Port various tools to make use of verbs.[ch], where applicable: busctl,
+ bootctl, coredumpctl, hostnamectl, localectl, systemd-analyze, timedatectl
* hostnamectl: show root image uuid
* as soon as we have kdbus, and 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
* 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
-* 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
-
* maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
* introduce systemd-timesync-wait.service or so to sync on an NTP fix?
* 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: maybe use the word "inspect" rather than "introspect"?
* 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.
-* exponential backoff in timesyncd and resolved when we cannot reach a server
+* exponential backoff in timesyncd when we cannot reach a server
-* timesyncd + resolved: add ugly bus calls to set NTP and DNS servers per-interface, for usage by NM
+* timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
* extract_many_words() should probably be used by a lot of code that
currently uses FOREACH_WORD and friends. For example, most conf
(throughout the codebase, not only PID1)
* 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
* refcounting in sd-resolve is borked
* 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 $container_headless= or so...
* figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
CAP_NET_ADMIN is set, more than the loopback device is defined, even
when it is otherwise off
-* MessageQueueMessageSize= and RLimitFSIZE= (and suchlike) should use parse_iec_size().
+* MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
* "busctl status" works only as root on dbus1, since we cannot read
/proc/$PID/exe
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
+* New service property: maximum CPU 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
* 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
- 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.
- generate a failure of a default event loop is executed out-of-thread
- maybe add support for inotify events
-* in the final killing spree, detect processes from the root directory, and
- complain loudly if they have argv[0][0] == '@' set.

-
* investigate endianness issues of UUID vs. GUID
* dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
* systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
-* 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
* shutdown logging: store to EFI var, and store to USB stick?
- journal-or-kmsg is currently broken? See reverted
commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
- man: document that corrupted journal files is nothing to act on
- - 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.
- 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
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
- - change journalctl -M to acquire fd to journal directory via machined, and
- then operate on that via openat() instead of absolute paths
- 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
- 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
- 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
- Modulate timer frequency based on battery state
* add libsystemd-password or so to query passwords during boot using the password agent logic
- 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
- - refuses to boot containers without /etc/machine-id (OK?), and with empty
- /etc/machine-id (not OK).
- nspawn -x should support ephemeral instances of gpt images
- emulate /dev/kmsg using CUSE and turn off the syslog syscall
with seccomp. That should provide us with a useful log buffer that
- should send out sd_notify("WATCHDOG=1") messages
- optionally automatically add FORWARD rules to iptables whenever nspawn is
running, remove them when shut down.
- - add a logic for cleaning up read-only, hidden container images in
- /var/lib/machines that are not ancestors of any non-hidden containers
- 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
removed or added to an existing machine
- "machinectl migrate" or similar to copy a container from or to a
difference host, via ssh
- - man: document how update dkr images works with machinectl
- http://lists.freedesktop.org/archives/systemd-devel/2015-February/028630.html
- 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
shell in it, and marks it read-only after use
* importd:
- - dkr: support tarsum checksum verification, if it becomes reality one day...
- - dkr: convert json bits to nspawn configuration
- generate a nice warning if mkfs.btrfs is missing
* cryptsetup:
* initialize the hostname from the fs label of /, if /etc/hostname does not exist?
-* rename "userspace" to "core-os"
-
* udev:
- move to LGPL
- kill scsi_id
* coredump:
- save coredump in Windows/Mozilla minidump format
- move PID 1 segfaults to /var/lib/systemd/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.
* support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
- Support --test based on current system state
- 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().
- after deserializing sockets in socket.c we should reapply sockopts and things
- - make timer units go away after they elapsed
- drop PID 1 reloading, only do reexecing (difficult: Reload()
currently is properly synchronous, Reexec() is weird, because we
cannot delay the response properly until we are back, so instead of
- Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
- consider adding RuntimeDirectoryUser= + RuntimeDirectoryGroup=
-* systemd-python:
- - figure out a simple way to wait for journal events in a way that
- works with ^C
- - add documentation to systemd.daemon
-
-* bootchart:
- - plot per-process IO utilization
- - group processes based on service association (cgroups)
- - document initcall_debug
- - kernel cmdline "bootchart" option for simplicity?
-
* udev-link-config:
- Make sure ID_PATH is always exported and complete for
network devices where possible, so we can safely rely
- work with non-Ethernet devices
- add support for more bond options
- dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
- - 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:
