Bugfixes:
|
|
|
|
* the error paths in usbffs_dispatch_ep() leak memory
|
|
|
|
* copy.c: set the right chattrs before copying files and others after
|
|
|
|
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
|
|
|
|
* rework mount.c and swap.c to follow proper state enumeration/deserialization
|
|
semantics, like we do for device.c now
|
|
|
|
Features:
|
|
|
|
* When reloading configuration PID 1 should reset all its properties to the
|
|
original defaults before calling parse_config()
|
|
|
|
* Add OnTimezoneChange= and OnTimeChange= stanzas to .timer units in order to
|
|
schedule events based on time and timezone changes.
|
|
|
|
* add O_TMPFILE support to copy_file_atomic()
|
|
|
|
* nspawn: greater control over selinux label?
|
|
|
|
* cgroups: figure out if we can somehow communicate in a cleaner way whether a
|
|
systemd instance not running in the cgroup root shall or shall not manage the
|
|
attributes of its top-level cgroup. Currently it assumes it manages all, but
|
|
then might get EPERM due to permission porblems/userns, which is OK, but this
|
|
should be revisited to make clearer and also work if the payload systemd runs
|
|
with full privs and without userns.
|
|
|
|
* portables: introduce a new unit file directory /etc/systemd/system.attached/
|
|
or so, where we attach portable services to
|
|
|
|
* cgroups: use inotify to get notified when somebody else modifies cgroups
|
|
owned by us, then log a friendly warning.
|
|
|
|
* beef up log.c with support for stripping ANSI sequences from strings, so that
|
|
it is OK to include them in log strings. This would be particularly useful so
|
|
that our log messages could contain clickable links for example for unit
|
|
files and suchlike we operate on.
|
|
|
|
* introduce a new SystemCallFilters= group called "@system-service" with a
|
|
sensible default set for system services, then make use of them in portable
|
|
profiles
|
|
|
|
* add support for "portablectl attach http://foobar.com/waaa.raw (i.e. importd integration)
|
|
|
|
* add attach --enable and attach --now (for attach+enable+start)
|
|
|
|
* sync dynamic uids/gids between host+portable srvice (i.e. if DynamicUser=1 is set for a service, make sure that the
|
|
selected user is resolvable in the service even if it ships its own /etc/passwd)
|
|
|
|
* Fix DECIMAL_STR_MAX or DECIMAL_STR_WIDTH. One includes a trailing NUL, the
|
|
other doesn't. What a desaster. Probably to exclude it. Also
|
|
DECIMAL_STR_WIDTH should probably add an extra "-" into account for negative
|
|
numbers.
|
|
|
|
* Check that users of inotify's IN_DELETE_SELF flag are using it properly, as
|
|
usually IN_ATTRIB is the right way to watch deleted files, as the former only
|
|
fires when a file is actually removed from disk, i.e. the link count drops to
|
|
zero and is not open anymore, while the latter happens when a file is
|
|
unlinked from any dir.
|
|
|
|
* port systemctl, systemd-inhibit, busctl, … over to format-table.[ch]'s table formatters
|
|
|
|
* pid1: lock image configured with RootDirectory=/RootImage= using the usual nspawn semantics while the unit is up
|
|
|
|
* add --vacuum-xyz options to coredumpctl, matching those journalctl already has.
|
|
|
|
* SuccessExitStatus= and friends should probably also accept symbolic exit
|
|
codes names, i.e. error codes from the list maintained in exit-codes.[ch]
|
|
|
|
* introduce Ephemeral= unit file switch, that creates an ephemeral copy of all
|
|
files and directories that are left writable for a unit, and which are
|
|
removed after the unit goes down again. A bit like --ephemeral for
|
|
systemd-nspawn but for system services. If used together with RootImage= this
|
|
should reflink the image file itself.
|
|
|
|
Related: add Ephemeral=<path1> <path2> … which would allow marking
|
|
specific paths only like this.
|
|
|
|
* add CopyFile= or so as unit file setting that may be used to copy files or
|
|
directory trees from the host to te services RootImage= and RootDirectory=
|
|
environment. Which we can use for /etc/machine-id and in particular
|
|
/etc/resolv.conf. Should be smart and do something useful on read-only
|
|
images, for example fallback to read-only bind mounting the file instead.
|
|
|
|
* nspawn's console TTY should be allocated from within the container, not
|
|
mounted in from the outside
|
|
|
|
* show invocation ID in systemd-run output
|
|
|
|
* bypass SIGTERM state in unit files if KillSignal is SIGKILL
|
|
|
|
* tree-wide: ensure we always block the signals we hook into with
|
|
sd_event_add_signal() first
|
|
|
|
* add proper dbus APIs for the various sd_notify() commands, such as MAINPID=1
|
|
and so on, which would mean we could report errors and such.
|
|
|
|
* teach tmpfiles.d q/Q logic something sensible in the context of XFS/ext4
|
|
project quota
|
|
|
|
* introduce DefaultSlice= or so in system.conf that allows changing where we
|
|
place our units by default, i.e. change system.slice to something
|
|
else. Similar, ManagerSlice= should exist so that PID1's own scope unit could
|
|
be moved somewhere else too. Finally machined and logind should get similar
|
|
options so that it is possible to move user session scopes and machines to a
|
|
different slice too by default. Usecase: people who want to put resources on
|
|
the entire system, with the exception of one specific service. See:
|
|
https://lists.freedesktop.org/archives/systemd-devel/2018-February/040369.html
|
|
|
|
* maybe rework get_user_creds() to query the user database if $SHELL is used
|
|
for root, but only then.
|
|
|
|
* be stricter with fds we receive for the fdstore: close them asynchronously
|
|
|
|
* calenderspec: add support for week numbers and day numbers within a
|
|
year. This would allow us to define "bi-weekly" triggers safely.
|
|
|
|
* add bpf-based implementation of devices cgroup controller logic for compat
|
|
with cgroupsv2 as supported by newest kernel
|
|
|
|
* introduce sd_id128_get_boot_app_specific() which is like
|
|
sd_id128_get_machine_app_specific(). After all on long-running systems both
|
|
IDs have similar properties.
|
|
|
|
* sd-bus: add vtable flag, that may be used to request client creds implicitly
|
|
and asynchronously before dispatching the operation
|
|
|
|
* make use of ethtool veth peer info in machined, for automatically finding out
|
|
host-side interface pointing to the container.
|
|
|
|
* add some special mode to LogsDirectory=/StateDirectory=… that allows
|
|
declaring these directories without necessarily pulling in deps for them, or
|
|
creating them when starting up. That way, we could declare that
|
|
systemd-journald writes to /var/log/journal, which could be useful when we
|
|
doing disk usage calculations and so on.
|
|
|
|
* taint systemd if there are fewer than 65536 users assigned (userns) to the system.
|
|
|
|
* deprecate PermissionsStartOnly= and RootDirectoryStartOnly= in favour of the ExecStart= prefix chars
|
|
|
|
* add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
|
|
the runtime dir as we maintain for the fdstore: i.e. keep it around as long
|
|
as the unit is running or has a job queued.
|
|
|
|
* support projid-based quota in machinectl for containers, and then drop
|
|
implicit btrfs loopback magic in machined
|
|
|
|
* Add NetworkNamespacePath= to specify a path to a network namespace
|
|
|
|
* maybe use SOURCE_DATE_EPOCH (i.e. the env var the reproducible builds folks
|
|
introduced) as the RTC epoch, instead of the mtime of NEWS.
|
|
|
|
* add a way to lock down cgroup migration: a boolean, which when set for a unit
|
|
makes sure the processes in it can never migrate out of it
|
|
|
|
* blog about fd store and restartable services
|
|
|
|
* document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
|
|
|
|
* rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
|
|
magic meaning and is no longer upgraded to something else if set explicitly.
|
|
|
|
* in the long run: permit a system with /etc/machine-id linked to /dev/null, to
|
|
make it lose its identity, i.e. be anonymous. For this we'd have to patch
|
|
through the whole tree to make all code deal with the case where no machine
|
|
ID is available.
|
|
|
|
* optionally, collect cgroup resource data, and store it in per-unit RRD files,
|
|
suitable for processing with rrdtool. Add bus API to access this data, and
|
|
possibly implement a CPULoad property based on it.
|
|
|
|
* beef up pam_systemd to take unit file settings such as cgroups properties as
|
|
parameters
|
|
|
|
* a new "systemd-analyze security" tool outputting a checklist of security
|
|
features a service does and does not implement
|
|
|
|
* maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
|
|
the quota of a the user indicated in User= via unit file settings, like the
|
|
other resource management concepts. Would mix nicely with DynamicUser=1. Or
|
|
alternatively, do this with projids, so that we can also cover services
|
|
running as root. Quota should probably cover all the special dirs such as
|
|
StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
|
|
is set, plus the whole disk space any image configured with RootImage=.
|
|
|
|
* Introduce "exit" as an EmergencyAction value, and allow to configure a
|
|
per-unit success/failure exit code to configure. This would be useful for
|
|
running commands inside of services inside of containers, which could then
|
|
propagate their failure state all the way up.
|
|
|
|
* In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
|
|
disks to see if the UID is already in use.
|
|
|
|
* add "systemctl wait" or so, which does what "systemd-run --wait" does, but
|
|
for all units. It should be both a way to pin units into memory as well as a
|
|
wait to retrieve their exit data.
|
|
|
|
* maybe set a new set of env vars for services, based on RuntimeDirectory=,
|
|
StateDirectory=, LogsDirectory=, CacheDirectory= and ConfigurationDirectory=
|
|
automatically. For example, there could be $RUNTIME_DIRECTORY,
|
|
$STATE_DIRECTORY, $LOGS_DIRECTORY=, $CACHE_DIRECTORY and
|
|
$CONFIGURATION_DIRECTORY or so. This could be useful to write services that
|
|
can adapt to varying directories for these purposes. Special care has to be
|
|
taken if multiple dirs are configured. Maybe avoid setting the env vars in
|
|
that case?
|
|
|
|
* expose IO accounting data on the bus, show it in systemd-run --wait and log
|
|
about it in the resource log message
|
|
|
|
* add "systemctl purge" for flushing out configuration, state, logs, ... of a
|
|
unit when it is stopped
|
|
|
|
* show whether a service has out-of-date configuration in "systemctl status" by
|
|
using mtime data of ConfigurationDirectory=.
|
|
|
|
* replace all uses of fgets() + LINE_MAX by read_line()
|
|
|
|
* 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
|
|
|
|
* 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.
|
|
|
|
* 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.
|
|
|
|
* 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.
|
|
|
|
* maybe introduce gpt auto discovery for /var/tmp?
|
|
|
|
* 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.
|
|
|
|
* 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?
|
|
|
|
* add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
|
|
then use that for the setting used in user@.service. It should be understood
|
|
relative to the configured default value.
|
|
|
|
* 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
|
|
|
|
* Permit masking specific netlink APIs with RestrictAddressFamily=
|
|
|
|
* 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()
|
|
|
|
* 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.
|
|
|
|
* 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)
|
|
|
|
* 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.
|
|
|
|
* 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
|
|
|
|
* 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
|
|
|
|
* 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
|
|
|
|
* 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?
|
|
|
|
* 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)
|
|
|
|
* 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
|
|
|
|
* 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
|
|
|
|
* 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
|
|
- port to sd-resolve for connecting to TCP dbus servers
|
|
- 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
|
|
- see if we can drop more message validation on the sending side
|
|
- add API to clone sd_bus_message objects
|
|
- longer term: priority inheritance
|
|
- dbus spec updates:
|
|
- NameLost/NameAcquired obsolete
|
|
- GVariant
|
|
- path escaping
|
|
- update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
|
|
|
|
* 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 (which we can do safely now, with O_PATH)
|
|
|
|
* 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...
|
|
|
|
* test/:
|
|
- add unit tests for config_parse_device_allow()
|
|
|
|
* 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?
|
|
|
|
* 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 getty@tty1.service 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?
|
|
- 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
|
|
- 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.
|
|
|
|
* 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.
|
|
- 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.
|
|
- 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
|
|
- 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
|
|
|
|
* add a test if all entries in the catalog are properly formatted.
|
|
(Adding dashes in a catalog entry currently results in the catalog entry
|
|
being silently skipped. journalctl --update-catalog must warn about this,
|
|
and we should also have a unit test to check that all our message are OK.)
|
|
|
|
* 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 that service reload may be implemented as service reexec
|
|
- 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
|
|
- 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
|
|
o timezone 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...
|
|
- optionally automatically add FORWARD rules to iptables whenever nspawn is
|
|
running, remove them when shut down.
|
|
- maybe make copying of /etc/resolv.conf optional, and skip it if --read-only
|
|
is used
|
|
|
|
* dissect
|
|
- refuse mounting over a mount point
|
|
- automatically discover .roothash files in dissect, similarly to nspawn
|
|
|
|
* machined:
|
|
- add an API so that libvirt-lxc can inform us about network interfaces being
|
|
removed or added to an existing machine
|
|
- "machinectl migrate" or similar to copy a container from or to a
|
|
difference host, via ssh
|
|
- introduce systemd-nspawn-ephemeral@.service, and hook it into
|
|
"machinectl start" with a new --ephemeral switch
|
|
- "machinectl status" should also show internal logs of the container in
|
|
question
|
|
- "machinectl list-images" should show os-release data, as well as
|
|
machine-info data (including deployment level)
|
|
- "machinectl history"
|
|
- "machinectl diff"
|
|
- "machinectl commit" that takes a writable snapshot of a tree, invokes a
|
|
shell in it, and marks it read-only after use
|
|
|
|
* importd:
|
|
- generate a nice warning if mkfs.btrfs is missing
|
|
|
|
* cryptsetup:
|
|
- cryptsetup-generator: allow specification of passwords in crypttab itself
|
|
- 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
|
|
|
|
* add a dependency on standard-conf.xml and other included files to man pages
|
|
|
|
* 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
|
|
|
|
* 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
|
|
- 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'
|
|
|
|
* pid1:
|
|
- 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
|
|
- introduce mix of BindTo and Requisite
|
|
- add a concept of RemainAfterExit= to scope units
|
|
- Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
|
|
|
|
* 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
|
|
|
|
* 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
|
|
|
|
* /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)
|
|
|
|
* 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
