Bugfixes:

* Should systemctl status \* work on all unit types, not just .service?

* Dangling symlinks of .automount unit files in .wants/ directories, set up

automount points even when the original .automount file did not exist

anymore. Only the .mount unit was still around.

* ExecStart with unicode characters fails in strv_split_extract:

[Service]

Environment=ONE='one' "TWO='two two' too" THREE=

ExecStart=/bin/python3 -c 'import sys;print(sys.argv)' $ONE $TWO $THREE

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

Janitorial Clean-ups:

* Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again

Features:

* Add AddUser= setting to unit files, similar to DynamicUser=1 which however

creates a static, persistent user rather than a dynamic, transient user. We

can leverage code from sysusers.d for this.

* add some optional flag to ReadWritePaths= and friends, that has the effect

that we create the dir in question when the service is started. Example:

ReadWritePaths=:/var/lib/foobar

* 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)

* set SystemCallArchitectures=native on all our services

* 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.

* tighten sd_notify() MAINPID= checks a bit: don't accept foreign PIDs (i.e.

PIDs not managed by the service manager)

* 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...

* 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

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* replace all canonicalize_file_name() invocations by chase_symlinks(), in

particulr those where a rootdir is relevant.

* maybe introduce gpt auto discovery for /var/tmp?

* set ProtectSystem=strict for all our usual services.

* fix PrivateNetwork= so that we fall back gracefully on kernels lacking

namespacing support (similar for the other namespacing options)

* 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)

* 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.

* 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.

* machined: add apis to query /etc/machine-info data of a container

* .mount and .swap units: add Format=yes|no option that formats the partition before mounting/enabling it, implicitly

* 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

* drop nss-myhostname in favour of nss-resolve?

* drop internal dlopen() based nss-dns fallback in nss-resolve, and rely on the

external nsswitch.conf based one

* add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and

then use that for the setting used in [email protected]. It should be understood

relative to the configured default value.

* on cgroupsv2 add DelegateControllers=, to pick the precise cgroup controllers to delegate

* in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us

* enable LockMLOCK to take a percentage value relative to physical memory

* switch to ProtectSystem=strict for all our long-running services where that's possible

* Permit masking specific netlink APIs with RestrictAddressFamily=

* nspawn: start UID allocation loop from hash of container name

* nspawn: support that /proc, /sys/, /dev are pre-mounted

* define gpt header bits to select volatility mode

* 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

* ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)

* ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)

* ProtectKeyRing= to take keyring calls away

* RemoveKeyRing= to remove all keyring entries of the specified user

* 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

* DeviceAllow= should also generate seccomp filters for mknod()

* Add DataDirectory=, CacheDirectory= and LogDirectory= to match

RuntimeDirectory=, and create it as necessary when starting a service, owned by the right user.

* 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

* mount: automatically search for "main" partition of an image has multiple

partitions

* expose the "privileged" flag of ExecCommand on the bus, and open it up to

transient units

* 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.

* allow attaching additional journald log fields to cgroups

* add bus API for creating unit files in /etc, reusing the code for transient units

* add bus API to remove unit files from /etc

* add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)

* 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

* 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

* 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)

* PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)

* 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

* man: document that unless you use StandardError=null the shell >/dev/stderr won't work in shell scripts in services

* 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 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

running units. Use this in timedated to manage the NTP service

state.

http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html

* Maybe add support for the equivalent of "ethtool advertise" to .link files?

http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html

* 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.

* networkd/udev: implement SR_IOV configuration in .link files:

http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html

* Rework systemctl's GetAll property parsing to use the generic bus_map_all_properties() API

* implement a per-service firewall based on net_cls

* Port various tools to make use of verbs.[ch], where applicable: busctl,

coredumpctl, hostnamectl, localectl, systemd-analyze, timedatectl

* hostnamectl: show root image uuid

* sysfs set api in libudev is not const

* Find a solution for SMACK capabilities stuff:

http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html

* "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)

* synchronize console access with BSD locks:

http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html

* as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:

http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html

* 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

* 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

* maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=

* 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

* 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.

* man: maybe use the word "inspect" rather than "introspect"?

* systemctl: if some operation fails, show log output?

* 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 when we cannot reach a server

* 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....

* systemd.show_status= should probably have a mode where only failed

units are shown.

* add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL

(throughout the codebase, not only PID1)

* resolved:

- mDNS/DNS-SD

- service registration

- service/domain/types browsing

- avahi compat

- DNS-SD service registration from socket units

- 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

* Add a new verb "systemctl top"

* add new gpt type for btrfs volumes

* support empty /etc boots nicely:

- nspawn/gpt-generator: introduce new gpt partition type for /usr

* generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.

* 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

* 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 bus api to query unit file's X fields.

* gpt-auto-generator:

- Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?

- Make /home automount rather than mount?

* 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

* 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

for ReusePort=

* socket units: support creating sockets in different namespace,

opening it up for JoinsNamespaceOf=. This would require to fork off

a tiny process that joins the namespace and creates/binds the socket

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.

* 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

it are fully stopped. This can later be used for app management by

desktop UIs such as gnome-shell to freeze apps that are not visible

on screen, not unlike how job control works on the shell

* cgroups:

- implement per-slice CPUFairScheduling=1 switch

- handle jointly mounted controllers correctly

- introduce high-level settings for RT budget, swappiness

- how to reset dynamically changed unit cgroup attributes sanely?

- when reloading configuration, apply new cgroup configuration

- when recursively showing the cgroup hierarchy, optionally also show

the hierarchies of child processes

* transient units:

- add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt

- ensure scope units may be started only a single time

* Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?

* when we detect low battery and no AC on boot, show pretty splash and refuse boot

* 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

* 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

* If we try to find a unit via a dangling symlink, generate a clean

error. Currently, we just ignore it and read the unit from the search

path anyway.

* 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.

* load .d/*.conf dropins for device units

* allow implementation of InaccessibleDirectories=/ plus

ReadOnlyDirectories=... for whitelisting files for a service.

* sd-bus:

- EBADSLT handling

- 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

- kdbus: maybe add controlling tty 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

- 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: matches against source or destination pids for an "strace -p"-like feel. Problem: The PID info needs to be available in userspace too...

- longer term: priority inheritance

- dbus spec updates:

- kdbus mapping

- NameLost/NameAcquired obsolete

- GVariant

- path escaping

- update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now

- test bloom filter generation indexes

- 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

- define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...

- generate a failure of a default event loop is executed out-of-thread

- maybe add support for inotify events

* investigate endianness issues of UUID vs. GUID

* dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we

should be able to safely try another attempt when the bus call LoadUnit() is invoked.

* add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.

* add a pam module that on password changes updates any LUKS slot where the password matches

* maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...

* cgtop: make cgtop useful in a container

* test/:

- add 'set -e' to scripts in test/

- make stuff in test/ work with separate output dir

* seems that when we follow symlinks to units we prefer the symlink

destination path over /etc and /usr. We should not do that. Instead

/etc should always override /run /usr and also any symlink

destination.

* when isolating, try to figure out a way how we implicitly can order

all units we stop before the isolating unit...

* teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})

* BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify

that the boot loader should be installed to the ESP. Define a way

how an installer can figure out whether a BLS compliant boot loader

is installed.

* think about requeuing jobs when daemon-reload is issued? usecase:

the initrd issues a reload after fstab from the host is accessible

and we might want to requeue the mounts local-fs acquired through

that automatically.

* 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

* shutdown logging: store to EFI var, and store to USB stick?

* 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()

* introduce ExecCondition= in services

* EFI:

- honor language efi variables for default language selection (if there are any?)

- honor timezone efi variables for default timezone selection (if there are any?)

- change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables

* maybe do not install [email protected] symlink in /etc but in /usr?

* 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.

* logind:

- logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around

- When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot

- logind: wakelock/opportunistic suspend support

- Add pretty name for seats in logind

- logind: allow showing logout dialog from system?

- we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case

- session scopes/user unit: add RequiresMountsFor for the home directory of the user

- add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.

- if pam_systemd is invoked by su from a process that is outside of a

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.

- 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

- 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.

* 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

- 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

- 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: 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.

- journal: store timestamp of journal_file_set_offline() int he header,

so it is possible to display when the file was last synced.

- 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: 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: 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?

- 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

full, make sure to write how many messages are lost as first thing

to syslog when it works again.

- journald: make sure ratelimit is actually really per-service with the new cgroup changes

- change systemd-journal-flush into a service that stays around during

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.

- 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

[Install] units of other units, unless those units are disabled

- man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets

- document the exit codes when services fail before they are exec()ed

- document that service reload may be implemented as service reexec

- document in wiki how to map ical recurrence events to systemd timer unit calendar specifications

- add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.

- 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: 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:

- 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

nothing. "systemctl enable" does nothing, and gives a bad message

about it. Should fix both to print nice actionable messages.

- print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service

- 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

- better error message if you run systemctl without systemd running

- 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

* timer units:

- timer units should get the ability to trigger when:

o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)

o DST changes

- Modulate timer frequency based on battery state

* add libsystemd-password or so to query passwords during boot using the password agent logic

* 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

* 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:

- 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 [email protected], 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

- move cryptsetup key caching into kernel keyctl?

https://bugs.freedesktop.org/show_bug.cgi?id=54982

- support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator

* hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it

https://bugs.freedesktop.org/show_bug.cgi?id=54712

* create /sbin/init symlinks from the build system

* MountFlags=shared acts as MountFlags=slave right now.

* properly handle loop back mounts via fstab, especially regards to fsck/passno

* initialize the hostname from the fs label of /, if /etc/hostname does not exist?

* udev:

- move to LGPL

- kill scsi_id

- add trigger --subsystem-match=usb/usb_device device

- reimport udev db after MOVE events for devices without dev_t

* when a service has the same env var set twice we actually store it twice and return that in systemctl show -p... We should only show the last setting

* There's currently no way to cancel fsck (used to be possible via C-c or c on the console)

* add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/

* coredump:

- save coredump in Windows/Mozilla minidump format

- when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps

* support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)

* default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max

* be able to specify a forced restart of service A where service B depends on, in case B

needs to be auto-respawned?

* tmpfiles:

- apply "x" on "D" too (see patch from William Douglas)

- replace F with f .

- instead of ignoring unknown fields, reject them.

- creating new directories/subvolumes/fifos/device nodes

should not follow symlinks. None of the other adjustment or creation

calls follow symlinks.

* make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early

* 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

assumes starting a service is enough to make it accessible

* Make it possible to set the keymap independently from the font on

the kernel cmdline. Right now setting one resets also the other.

* and a dbus call to generate target from current state

* write blog stories about:

- hwdb: what belongs into it, lsusb

- enabling dbus services

- status update

- 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

- testing with Harald's awesome test kit

- auto-restart

- how to develop against journal browsing APIs

- the journal HTTP iface

- non-cgroup resource management

- dynamic resource management with cgroups

- refreshed, longer missions statement

- calendar time events

- init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell

- how to create your own target

- instantiated apache, dovecot and so on

- hooking a script into various stages of shutdown/rearly booot

* investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.

* dot output for --test showing the 'initial transaction'

* fingerprint.target, wireless.target, gps.target, netdevice.target

* pid1:

- .timer units should optionally support CLOCK_BOOTTIME in addition to CLOCK_MONOTONIC

- When logging about multiple units (stopping BoundTo units, conflicts, etc.),

log both units as UNIT=, so that journalctl -u triggers on both.

- 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

- maybe introduce WantsMountsFor=? Usecase:

http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html

- recreate systemd's D-Bus private socket file on SIGUSR2

- move PAM code into its own binary

- when we automatically restart a service, ensure we restart its rdeps, too.

- hide PAM options in fragment parser when compile time disabled

- 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

- 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

being properly synchronous we just keep open the fd and close it

when done. That means clients do not get a successful method reply,

but much rather a disconnect on success.

- when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr

- when a bus name of a service disappears from the bus make sure to queue further activation requests

* unit files:

- allow port=0 in .socket units

- maybe introduce ExecRestartPre=

- add ReloadSignal= for configuring a reload signal to use

- implement Register= switch in .socket units to enable registration

in Avahi, RPC and other socket registration services.

- allow Type=simple with PIDFile=

https://bugzilla.redhat.com/show_bug.cgi?id=723942

- allow writing multiple conditions in unit files on one line

- load-fragment: when loading a unit file via a chain of symlinks

verify that it is not masked via any of the names traversed.

- introduce Type=pid-file

- ExecOnFailure=/usr/bin/foo

- introduce mix of BindTo and Requisite

- add a concept of RemainAfterExit= to scope units

- Set NoNewPrivileges= on all of our own services, where that makes sense

- Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely

- consider adding RuntimeDirectoryUser= RuntimeDirectoryGroup=

* udev-link-config:

- Make sure ID_PATH is always exported and complete for

network devices where possible, so we can safely rely

on Path= matching

- check MTUBytes parsing (expecting size_t but we are using unsigned)

* sd-rtnl:

- add support for more attribute types

- inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places

* networkd:

- add more keys to [Route] and [Address] sections

- add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)

- add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)

- add reduced [Link] support to .network files

- add Scope= parsing option for [Network]

- properly handle routerless dhcp leases

- 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?

- 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 123, 144, geolocation

- option 252, configure http proxy (PAC/wpad)

- 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.

- whenever uplink info changes, make DHCP server send out FORCERENEW

* networkd-wait-online:

- make operstates to wait for configurable?

* dhcp:

- figure out how much we can increase Maximum Message Size

- support RFC4702 (pass FQDN)

* dhcp6:

- add functions to set previously stored IPv6 addresses on startup and get

them at shutdown; store them in client->ia_na

- write more test cases

- implement reconfigure support, see 5.3., 15.11. and 22.20.

- implement support for temporary adressess (IA_TA)

- 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

or interface down

- some servers don't do rapid commit without a filled in IA_NA, verify

this behavior

- RouteTable= ?

External:

* dbus:

- natively watch for dbus-*.service symlinks (PENDING)

- teach dbus to activate all services it finds in /etc/systemd/services/org-*.service

* fix alsa mixer restore to not print error when no config is stored

* make cryptsetup lower --iter-time

* patch kernel for xattr support in /dev, /proc/, /sys?

* kernel: add device_type = "fb", "fbcon" to class "graphics"

* drop accountsservice's StandardOutput=syslog and Type=dbus fields

* dbus: in fedora, make /var/lib/dbus/machine-id a symlink to /etc/machine-id

* /usr/bin/service should actually show the new command line

* fedora: suggest auto-restart on failure, but not on success and not on coredump. also, ask people to think about changing the start limit logic. Also point people to RestartPreventExitStatus=, SuccessExitStatus=

* fedora: F20: go timer units all the way, leave cron.daily for cron

* neither pkexec nor sudo initialize environ[] from the PAM environment?

* fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it

* register catalog database signature as file magic

* zsh shell completion:

- <command> <verb> -<TAB> should complete options, but currently does not

- systemctl add-wants,add-requires

Regularly:

* look for close() vs. close_nointr() vs. close_nointr_nofail()

* check for strerror(r) instead of strerror(-r)

* Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel

* pahole

* set_put(), hashmap_put() return values check. i.e. == 0 does not free()!

* use secure_getenv() instead of getenv() where appropriate

* link up selected blog stories from man pages and unit files Documentation= fields
