+Preparations for 218:
+
+* port libmount hookup to use API's own inotify interface
+
+* rhbz
+
+* Backport: git notes
+
Bugfixes:
-* Re-enable "fsck -l" when it is ready:
- https://bugs.freedesktop.org/show_bug.cgi?id=79576#c5
* Should systemctl status \* work on all unit types, not just .service?
* properly handle .mount unit state tracking when two mount points are stacked one on top of another on the exact same mount point.
+* ExecStart with unicode characters fails in strv_split_quoted:
+
+ [Service]
+ Environment=ONE='one' "TWO='two two' too" THREE=
+ ExecStart=/bin/python3 -c 'import sys;print(sys.argv)' $ONE $TWO $THREE
+
+* MEMORY return code is overloaded for syntax errors in the command line.
+ str_split_quoted() should return a real return code, so spawn_child can
+ report the failure properly.
+
External:
+
* Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
* Fedora: post FPC ticket to move add %tmpfiles_create to the packaging guidelines
* Fedora: remove /etc/resolv.conf tmpfiles hack
+* 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.
+
Features:
-* maybe add "systemctl edit" that copies unit files from /usr/lib/systemd/system to /etc/systemd/system and invokes vim on them
+* "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)
-* dbus: add new message hdr field for allowing interactive auth, write spec for it. update dbus spec to mandate that unknown flags *must* be ignored...
+* 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.
-* maybe introduce AssertXYZ= similar to ConditionXYZ= that causes a unit to fail (instead of skipping it) if some condition is not true...
+* systemd-journal-upload (or a new, related tool): allow pushing out
+ journal messages onto the network in BSD syslog protocol,
+ continously. Default to some link-local IP mcast group, to make this
+ useful as a one-stop debugging tool.
-* remove multi-seat-x now
+* synchronize console access with BSD locks:
+ http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
-* refcounting in sd-resolve is borked
+* 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
-* exponential backoff in timesyncd and resolved when we cannot reach a server
+* set $REMOTE_IP (or $REMOTE_ADDR/$REMOTE_PORT) environment variable when doing per-connection socket activation. use format introduced by xinetd or CGI for this
+
+* 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
+
+* we should try harder to collapse start jobs for swaps that end up being the same:
+ http://lists.freedesktop.org/archives/systemd-devel/2014-November/025359.html
+
+* timedated should compensate on SetTime for the time spent in polkit
+
+* figure out what to do with libmount and utab?
+
+* We really should have a FOREACH macro to iterate through inotify events we read, similar to KDBUS_FOREACH_ITEM
+
+* 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
+ returning from the "systemctl stop".
+
+* 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
+
+* networkd-wait-online really should have a timeout by default
+
+* 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 unquote_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
+
+* configure.ac pretends dbus was optional but actually hardcodes use of dbus' pkg-config file to determine various dbus dirs such as policy and activation dirs
+
+* 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?
-* apply start timeout during the "initializing" manager state only,
- instead of both "initializing" and "starting". maybe rename the
- timeout to "initialization-timeout" then or so?
+* maybe allow timer units with an empty Units= setting, so that they
+ can be used for resuming the system but nothing else.
-* journald: make use of uid-range.h to managed uid ranges to split
- journals in.
+* what to do about udev db binary stability for apps? (raw access is not an option)
+
+* 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: add commented help text to the end, like git commit
+
+* refcounting in sd-resolve is borked
+
+* exponential backoff in timesyncd and resolved when we cannot reach a server
* tmpfiles: port to unquote_many_words(), similar to sysusers
currently uses FOREACH_WORD and friends. For example, most conf
parsing callbacks should use it.
-* logind: make the Suspend()/Hibernate() bus calls wait for the for
- the job to be completed. before returning, so that clients can wait
- for "systemctl suspend" to finish to know when the suspending is
- complete.
-
* merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
-* remove readahead in 217
-
-* journald: allows specification of UID range for splitting up journal files
-
* systemd.show_status= should probably have a mode where only failed
units are shown.
* networkd:
- add LLDP client side support
- - ipv4ll with multiple interfaces doesn't work when both dhcp and
- ipv4ll is used. for some reasons the kernel will currently pick an
- ipv4ll source address to reach non-ipv4ll gateways.
- - dhcp and ipv4ll should probably be skipped for "lo" devices, even
- if the user has a catchall .network file installed, that might
- theoretically match it.
- 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.
- .network setting that allows overriding of the hostname to send to the dhcp server
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 ?
* resolved:
- put networkd events and rtnl events at a higher priority, so that
- edns0
- dname
- cname on PTR (?)
-
-* Ignore .busname units on classic D-Bus boots, systemd-resolved cannot be started on kdbus
- without the active policy and should get a Wants=org.freedesktop.resolve1.busname to
- pull-in the policy.
+ - maybe randomize DNS UDP source ports
+ - maybe compare query section of DNS replies
* Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
* Add a new verb "systemctl top"
-* logind: allow users to kill or lock their own sessions
-
* add new gpt type for btrfs volumes
* 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=
- - fstab-generator: add support for usr= in addition to root= on the kernel cmdline
* generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
-* support setting empty environment variables with Environment= and EnvironmentFile=
-
* 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
-* journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
-
-* set NOTIFY_SOCKET also for control processes
-
* mount_cgroup_controllers(): symlinks need to get the label applied
* For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
* sd-event: generate a failure of a default event loop is executed out-of-thread
-* expose "Locked" property on logind sesison objects
-
* add bus api to query unit file's X fields.
* consider adding RuntimeDirectoryUser= + RuntimeDirectoryGroup=
- Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
- Make /home automount rather than mount?
-* improve journalctl performance by loading journal files
- 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.
-
* add generator that pulls in systemd-network from containers when
CAP_NET_ADMIN is set, more than the loopback device is defined, even
when it is otherwise off
* refuse boot if /etc/os-release is missing or /etc/machine-id cannot be set up
-* given that logind now lets PID 1 do all nasty work, we can
- probably reduce the capability set it retains substantially.
- (we need CAP_SYS_ADMIN for drmSetMaster(), so maybe not worth it)
-
* 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
ReadOnlyDirectories=... for whitelisting files for a service.
* sd-bus:
+ - make dsrt happy, and change userspace header for kdbus to yyyyuta{tv}v
+ - kdbus: PID/TID goes missing for method calls from outside the PID namespace?
+ - kdbus: the kernel should not allow messages to be delivered that have a reply serial != 0, reply-expect unset, but no appropriate window
+ - kdbus: timestamps on kernel's NameOwnerChanged messages?
+ - kdbus' busnames.target should get pulled in by basic.target
+ - Ignore .busname units on classic D-Bus boots, systemd-resolved cannot be started on kdbus
+ without the active policy and should get a Wants=org.freedesktop.resolve1.busname to
+ pull-in the policy.
+ - port to sd-resolve for connecting to TCP dbus servers
+ - kdbus: maybe add controlling tty and ppid metadata fields
+ - see if we can introduce a new sd_bus_get_owner_machine_id() call to retrieve the machine ID of the machine of the bus itself
- when kdbus does not take our message without memfds, try again with memfds
- - systemd-bus-proxyd needs to enforce good old XML policy
- - allow updating attach flags during runtime
- - pid1: peek into activating message when activating a service
- introduce sd_bus_emit_object_added()/sd_bus_emit_object_removed() that automatically includes the build-in interfaces in the list
- - port to sd-resolve for connecting to TCP dbus servers
- see if we can drop more message validation on the sending side
- add API to clone sd_bus_message objects
- make AddMatch calls on dbus1 transports async?
- kdbus mapping
- NameLost/NameAcquired obsolete
- GVariant
- - "const" properties (posted)
- 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 a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
-* timedatectl: print a nicer message when enabling ntp fails because ntpd/chrony are not installed
-
* cgtop: make cgtop useful in a container
* test/:
* think about window-manager-run-as-user-service problem: exit 0 → activate shutdown.target; exit != 0 → restart service
-* use "log level" rather than "log priority" everywhere
-
* merge unit_kill_common() and unit_kill_context()
* introduce ExecCondition= in services
any session we should probably just become a NOP, since that's
usually not a real user session but just some system code that just
needs setuid().
+ - logind: make the Suspend()/Hibernate() bus calls wait for the for
+ the job to be completed. before returning, so that clients can wait
+ for "systemctl suspend" to finish to know when the suspending is
+ complete.
+ - logind: when the power button is pressed short, just popup a
+ logout dialog. If it is pressed for 1s, do the usual
+ shutdown. Inspiration are Macs here.
+ - logind: allow users to kill or lock their own sessions
+ - expose "Locked" property on logind sesison objects
+ - given that logind now lets PID 1 do all nasty work, we can
+ 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
* exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
* service: watchdog logic: for testing purposes allow ping, but do not require pong
* journal:
+ - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
- import and delete pstore filesystem content at startup
- journald: also get thread ID from client, plus thread name
- journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
- journal-send.c, log.c: when the log socket is clogged, and we drop, count this and write a message about this when it gets unclogged again.
- journal: find a way to allow dropping history early, based on priority, other rules
- journal: When used on NFS, check payload hashes
- - journald: check whether it is OK if the client can still modify delivered journal entries
- journal live copy, based on libneon (client) and libmicrohttpd (server)
- journald: add kernel cmdline option to disable ratelimiting for debug purposes
- refuse taking lower-case variable names in sd_journal_send() and friends.
- journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
- journal: deal nicely with byte-by-byte copied files, especially regards header
- - journal: store euid in journal if it differs from uid
- journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
- Replace utmp, wtmp, btmp, and lastlog completely with journal
- journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
- - tmpfiles: when applying ownership to /run/log/journal, also do this for the journal fails contained in it
- when a kernel driver logs in a tight loop, we should ratelimit that too.
- journald: optionally, log debug messages to /run but everything else to /var
- journald: when we drop syslog messages because the syslog socket is
boot, and causes the journal to be moved back to /run on shutdown,
so that we do not keep /var busy. This needs to happen synchronously,
hence doing this via signals is not going to work.
+ - optionally support running journald from the command line for testing purposes in external projects
+ - journald: allow per-priority and per-service retention times when rotating/vacuuming
+ - journald: make use of uid-range.h to managed uid ranges to split
+ journals in.
+ - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
+ - improve journalctl performance by loading journal files
+ 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.
* document:
- document that deps in [Unit] sections ignore Alias= fields in
- "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)
- - systemctl: maybe add "systemctl add-wants" or so...
* timer units:
- timer units should get the ability to trigger when:
- 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
-* update the kernel's TZ (sys_tz) when DST changes
-
-* sync down the system time to the RTC when:
- - CLOCK_REALTIME makes jumps (the user explicitely requested a time set)
- - DST/timezone changes && ntp is active && RTC-in-localtime (never do it without ntp)
- This takes care of syncing ntpdate updates to the RTC, and DST updates for localtime
- mode, it will never touch the RTC if the no reliable time source is active or the
- user did not request anything like it.
-
* 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().
- bind mount read-only the cgroup tree higher than nspawn
- refuses to boot containers without /etc/machine-id (OK?), and with empty /etc/machine-id (not OK).
- support taking a btrfs snapshot at startup and dropping it afterwards
+ - introduce machines.target to order after all nspawn instances
+ - systemd-nspawn@.service should fail if some nspawn arg is invalid, with Type=notify
+ - PID 1 doesn't apply nspawns devices cgroup policy
* cryptsetup:
- cryptsetup-generator: allow specification of passwords in crypttab itself
* make timer units go away after they elapsed
-* come up with a nice way to write queue/read_ahead_kb for a block device without interfering with readahead
-
* move PID 1 segfaults to /var/lib/systemd/coredump?
* create /sbin/init symlinks from the build system
* and a dbus call to generate target from current state
-* readahead:
- - drop /.readahead on bigger upgrades with yum
- - move readahead files into /var (look for them with .path units?)
- - readahead: use BTRFS_IOC_DEFRAG_RANGE instead of BTRFS_IOC_DEFRAG ioctl, with START_IO
- - readahead: when bumping /sys readahead variable save mtime and compare later to detect changes
- - readahead: make use of EXT4_IOC_MOVE_EXT, as used by http://e4rat.sourceforge.net/
-
* GC unreferenced jobs (such as .device jobs)
* write blog stories about:
- how to make changes to sysctl and sysfs attributes
- remote access
- how to pass throw-away units to systemd, or dynamically change properties of existing units
- - how to integrate cgconfig and suchlike with systemd
- testing with Harald's awesome test kit
- auto-restart
- how to develop against journal browsing APIs
* fingerprint.target, wireless.target, gps.target, netdevice.target
-* drop cap bounding set in readahead and other services
-
* systemd-python:
- figure out a simple way to wait for journal events in a way that
works with ^C
- implement reconfigure support, see 5.3., 15.11. and 22.20.
- implement information request, see 1.2. and 18.1.5.
- implement support for temporary adressess (IA_TA)
- - implement elapsed time option
- implement dhcpv6 authentication
- investigate the usefulness of Confirm messages; i.e. are there any
situations where the link changes without any loss in carrier detection
* register catalog database signature as file magic
-* zsh shell completion: <command> <verb> -<TAB> should complete options, but currently
- does not
+* zsh shell completion:
+ - <command> <verb> -<TAB> should complete options, but currently does not
+ - systemctl add-wants,add-requires, edit
+
