| 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 |
| |
| * copy.c: set the right chattrs before copying files and others after |
| |
| * rework mount.c and swap.c to follow proper state enumeration/deserialization |
| semantics, like we do for device.c now |
| |
| Features: |
| |
| * the stop-when-unneded feature should be reworked: there should be a queue of |
| units, and we should only enqeueu stop jobs from a defer event that processes |
| queue instead of right-away when we assume that a unit is now unneeded. |
| |
| * 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. |
| |
| * 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, ... |
| - 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() |
| |
| * 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 |
