+Preparations for 218:
+
+* cgroup delegation issues
+
+* test-bus-kernel-bloom is borked
+
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: when installing fedora with yum --installroot /var/run is a directory, not a symlink
- https://bugzilla.redhat.com/show_bug.cgi?id=975864
* Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
* 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:
-* journald: allows specification of UID range for splitting up journal files
+* port libmount hookup to use API's own inotify interface, as soon as that is table in libmount
+
+* bash completion for busctl, to make it truly useful
+
+* journald: broken file systems are real (btrfs), we need to handle
+ SIGBUS in some way if we cannot write or read from the disk.
+ https://bugzilla.redhat.com/show_bug.cgi?id=1151848
+
+* "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,
+ continously. 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:
+ http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
+
+* 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?
+
+* maybe allow timer units with an empty Units= setting, so that they
+ can be used for resuming the system but nothing else.
+
+* 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
+
+* unquote_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.
+
+* merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
* systemd.show_status= should probably have a mode where only failed
units are shown.
-* sd-event: - make it possible to embedd our event loop into foreign
- event loops by passing out the epoll fd and providing three functions
- that fit into GSource nicely.
-
* networkd:
- - add LLDP 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.
- - we probably should introduce a new operational state that
- indicates that we are trying to acquire some configuration for a
- link but haven't acquired any yet. Just to inform the admin that
- networkd cares about an interface, but is still in progress..
+ - 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.
- .network setting that allows overriding of the hostname to send to the dhcp server
http://lists.freedesktop.org/archives/systemd-devel/2014-July/021550.html
- - add per-network Domains= settings, with a special syntax Domains=*
- for routing all non-otherwise routed traffic to this link
- - add UseDomains= setting to [DHCP] to add dhcp supplied domains to
- per-interface Domains= list.
- 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
- 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 ?
* resolved:
+ - put networkd events and rtnl events at a higher priority, so that
+ we always process them before we process client requests
- DNSSEC
- use base64 for key presentation?
- add display of private key types (http://tools.ietf.org/html/rfc4034#appendix-A.1.1)?
- 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
-* the resolv.conf tmpfiles line should be covered by ENABLE_NETWORKD...
-
-* sysusers:
- - also create entries in /etc/shadow, /etc/gshadow
- - allow setting the home directory of system users
- - allow configuration of ranges to allocate items in
- - add mode where we read sysusers data from stdin, so that we can run this from rpm scriptlets
-
* Add a new verb "systemctl top"
-* refuse mounting on symlinks
-
-* 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=
-
-* machined/machinectl: sort IP addresses we return by scope and protocol
-* machined: write NSS module for looking up IP addresses for machines
-
* 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
they run added to the initial transaction and thus confuse Type=idle.
-* Add timeout to early-boot, and shut down the system if it is hit. Solves the laptop-in-bag problem and is useful for embedded cases
-
* 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
-* 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
* unify dispatch table in systemctl_main() and friends
-* Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
-
* 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
* 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:
+ - kdbus: process fd=-1 for incoming msgs
+ - make dsrt happy, and change userspace header for kdbus to yyyyuta{tv}v
+ - kdbus: remove NameOwnerChanged kernel messages for monitors
+ - 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...
-* timedatctl, localectl: possibly make some commands work without the daemon, for chroot situations...
-
-* 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
* properly handle loop back mounts via fstab, especially regards to fsck/passno
-* allow services with no ExecStart= but with an ExecStop=
-
-* dracut-shutdown needs to be ordered before unmounting /boot
-
* initialize the hostname from the fs label of /, if /etc/hostname does not exist?
* rename "userspace" to "core-os"
* ExecOnFailure=/usr/bin/foo
* udev:
- - remove src/udev/udev-builtin-firmware.c (CONFIG_FW_LOADER_USER_HELPER=n)
- move to LGPL
- kill scsi_id
- add trigger --subsystem-match=usb/usb_device device
* make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
-* support sd_notify() style notification when reload begins (RELOADING=1), reload is finished (READY=1), and add ReloadSignal= then to use in combination
-
-* support sd_notify() style notification when shutting down, to make auto-exit bus services work (STOPPING=1)
+* add ReloadSignal= for configuring a reload signal to use
* verify that the AF_UNIX sockets of a service in the fs still exist
when we start a service in order to avoid confusion when a user
* 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
