Bugfixes:
|
|
|
|
* Many manager configuration settings that are only applicable to user
|
|
manager or system manager can be always set. It would be better to reject
|
|
them when parsing config.
|
|
|
|
* userdbctl: "Password OK: yes" is shown even when there are no passwords
|
|
or the password is locked.
|
|
|
|
External:
|
|
|
|
* Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
|
|
|
|
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:
|
|
|
|
* cryptsetup: optionally, when run during boot-up and password is never
|
|
entered, and we are on AC power (or so), power off machine again
|
|
|
|
* when configuring loopback netif, and it fails due to EPERM, eat up error if
|
|
it happens to be set up alright already.
|
|
|
|
* at boot: check if battery above some threshold, if not power off again after explanation
|
|
|
|
* userdb: add field for ambient caps, so that a user can have CAP_WAKE_ALARM
|
|
for example. And add code that resets ambient caps for all services by
|
|
default.
|
|
|
|
* homed: try to unmount in regular intervals when home dir was busy when we
|
|
tried because idle.
|
|
|
|
* sd-bus: when connecting to some dbus server socker, set originating AF_UNIX
|
|
socket name in abstract namespace to include "description" string, and pick
|
|
it up from there in sd_bus_creds logic. i.e. we can use the socket peer
|
|
address as conduit for some minimal connection metainfo, and use it to
|
|
restore the "description" logic that kdbus used to have.
|
|
|
|
* teach LoadCredential= the ability to load all files from a specified dir as
|
|
individual creds
|
|
|
|
* systemd-analyze netif that explains predictable interface (or networkctl)
|
|
|
|
* port selinux code from mallinfo() to mallinfo2() once added to glibc
|
|
|
|
* Add service setting to run a service within the specified VRF. i.e. do the
|
|
equivalent of "ip vrf exec".
|
|
|
|
* export action of device object on sd-device, so that monitor becomes useful
|
|
|
|
* add root=tmpfs that mounts a tmpfs to /sysroot (to be used in combination
|
|
with usr=…, for a similar effect as systemd.volatile=yes but without the
|
|
"hide-out" effect). Also, add root=gpt-auto-late support or so, that is like
|
|
root=gpt-auto but initially mounts a tmpfs to /sysroot, and then revisits
|
|
later after systemd-repart ran. Usecase: let's ship images with only /usr
|
|
partition, then on first boot create the root partition. In this case we want
|
|
to read the repart data from /usr before the root partition exists. Add
|
|
usr=gpt-auto that automatically finds a /usr partition.
|
|
|
|
* change SwitchRoot() implementation in PID 1 to use pivot_root(".", "."), as
|
|
documented in the pivot_root(2) man page, so that we can drop the /oldroot
|
|
temporary dir.
|
|
|
|
* special case some calls of chase_symlinks() to use openat2() internally, so
|
|
that the kernel does what we otherwise do.
|
|
|
|
* homed: keep an fd to the homedir open at all times, to keep the fs pinned
|
|
(autofs and such) while user is logged in.
|
|
|
|
* nss-systemd: also synthesize shadow records for users/groups
|
|
|
|
* make use of new glibc 2.32 APIs sigabbrev_np() and strerrorname_np().
|
|
|
|
* cryptsetup: if keyfile specified in crypttab is AF_UNIX socket, connect to it
|
|
and read from it (like we do elsewhere with READ_FULL_FILE_CONNECT_SOCKET)
|
|
|
|
* when main nspawn supervisor process gets suspended due to SIGSTOP/SIGTTOU or
|
|
so, freeze the payload too.
|
|
|
|
* repart: support setting up dm-integrity with HMAC
|
|
|
|
* add /etc/integritytab, to support dm-integrity setups. In particular those
|
|
with HMAC as hash function, so that we can have a protected /home without
|
|
encryption (leaving encryption to the individual dirs/homed).
|
|
|
|
* complement root=, rootflags=, rootfstype= with rootsubdir= which allows
|
|
mounting a subdir of the root fs as actual root. This can be used as
|
|
fstype-agnostic version of btrfs' rootflags=subvol=foobar.
|
|
|
|
* if /usr/bin/swapoff fails due to OOM, log a friendly explanatory message about it
|
|
|
|
* build short web pages out of each catalog entry, build them along with man
|
|
pages, and include hyperlinks to them in the journal output
|
|
|
|
* machined: add API to acquire UID range. add API to mount/dissect loopback
|
|
file. Both protected by PK. Then make nspawn use these APIs to run
|
|
unprivileged containers. i.e. push the truly privileged bits into machined,
|
|
so that the client side can remain entirely unprivileged, with SUID or
|
|
anything like that.
|
|
|
|
* journald: do journal file writing out-of-process, with one writer process per
|
|
client UID, so that synthetic hash table collisions can slow down a specific
|
|
user's journal stream down but not the others.
|
|
|
|
* add "throttling" to sd-event event sources: optionally, when we wake up too
|
|
often for one, let's turn it off entirely for a while. Use that for the
|
|
/proc/self/mountinfo logic.
|
|
|
|
* nspawn: support time namespaces
|
|
|
|
* systemd-firstboot: make sure to always use chase_symlinks() before
|
|
reading/writing files
|
|
|
|
* add ConditionSecurity=tpm2
|
|
|
|
* Remove any support for booting without /usr pre-mounted in the initrd entirely.
|
|
Update INITRD_INTERFACE.md accordingly.
|
|
|
|
* pid1: Move to tracking of main pid/control pid of units per pidfd
|
|
|
|
* pid1: support new clone3() fork-into-cgroup feature
|
|
|
|
* pid1: also remove PID files of a service when the service starts, not just
|
|
when it exits
|
|
|
|
* make us use dynamically fewer deps for containers in general purpose distros:
|
|
o turn into dlopen() deps:
|
|
- elfutils (always)
|
|
- p11-kit-trust (always)
|
|
- kmod-libs (only when called from PID 1)
|
|
- libblkid (only in RootImage= handling in PID 1, but not elsewhere)
|
|
- libpam (only when called from PID 1)
|
|
- bzip2, xz, lz4 (always — gzip and zstd should probably stay static deps the way they are,
|
|
since they are so basic and our defaults)
|
|
o move into separate libsystemd-shared-iptables.so .so
|
|
- iptables-libs (only used by nspawn + networkd)
|
|
|
|
* seccomp: when SystemCallArchitectures=native is set then don't install any
|
|
other seccomp filters for any of the other archs, in order to reduce the
|
|
number of seccomp filters we install needlessly.
|
|
|
|
* seccomp: maybe use seccomp_merge() to merge our filters per-arch if we can.
|
|
Apparently kernel performance is much better with fewer larger seccomp
|
|
filters than with more smaller seccomp filters.
|
|
|
|
* systemd-path: add ESP and XBOOTLDR path. Add "private" runtime/state/cache dir enum,
|
|
mapping to $RUNTIME_DIRECTORY, $STATE_DIRECTORY and such
|
|
|
|
* All tools that support --root= should also learn --image= so that they can
|
|
operate on disk images directly. Specifically: bootctl, systemctl,
|
|
coredumpctl. (Already done: systemd-nspawn, systemd-firstboot,
|
|
systemd-repart, systemd-tmpfiles, systemd-sysusers, journalctl)
|
|
|
|
* seccomp: by default mask x32 ABI system wide on x86-64. it's on its way out
|
|
|
|
* seccomp: don't install filters for ABIs that are masked anyway for the
|
|
specific service
|
|
|
|
* seccomp: maybe merge all filters we install into one with that libseccomp API that allows merging.
|
|
|
|
* credentials system:
|
|
- maybe add AcquireCredential= for querying a cred via ask-password
|
|
- maybe try to acquire creds via keyring?
|
|
- maybe try to pass creds via keyring?
|
|
- maybe optionally pass creds via memfd
|
|
- maybe add support for decrypting creds via TPM
|
|
- maybe add support for decrypting/importing creds via pkcs11
|
|
- make systemd-cryptsetup acquire pw via creds logic
|
|
- make PAMName= acquire pw via creds logic
|
|
- make macsec/wireguard code in networkd read key via creds logic
|
|
- make gatwayd/remote read key via creds logic
|
|
- add sd_notify() command for flushing out creds not needed anymore
|
|
|
|
* homed: during login resize fs automatically towards size goal. Specifically,
|
|
resize to diskSize if possible, but leave a certain amount (configured by a
|
|
new value diskLeaveFreeSize) of space free on the backing fs.
|
|
|
|
* homed: permit multiple user record signing keys to be used locally, and pick
|
|
the right one for signing records automatically depending on a pre-existing
|
|
signature
|
|
|
|
* homed: add a way to "adopt" a home directory, i.e. strip foreign signatures
|
|
and insert a local signature instead.
|
|
|
|
* homed: as an extension to the directory+subvolume backend: if located on
|
|
especially marked fs, then sync down password into LUKS header of that fs,
|
|
and always verify passwords against it too. Bootstrapping is a problem
|
|
though: if no one is logged in (or no other user even exists yet), how do you
|
|
unlock the volume in order to create the first user and add the first pw.
|
|
|
|
* homed: support new FS_IOC_ADD_ENCRYPTION_KEY ioctl for setting up fscrypt
|
|
|
|
* homed: maybe pre-create ~/.cache as subvol so that it can have separate quota
|
|
easily?
|
|
|
|
* busctl: maybe expose a verb "ping" for pinging a dbus service to see if it
|
|
exists and responds.
|
|
|
|
* when systemd-nspawn and suchlike dissect an OS image, and there are multiple
|
|
root partitions, do an strverscmp() on the partition label and boot
|
|
first. That is inspired how sd-boot figures out which kernel to boot, and
|
|
thus allows defining OS images which can be A/B updated and we default to the
|
|
newest version automatically, both in nspawn and in sd-boot
|
|
|
|
* cryptsetup: support FIDO2 tokens for deriving keys (i.e. do what homed can do
|
|
also in plain cryptsetup)
|
|
|
|
* systemd-gpt-auto should probably set x-systemd.growfs on the mounts it
|
|
creates
|
|
|
|
* bootctl:
|
|
- teach it to prepare an ESP wholesale, i.e. with mkfs.vfat invocation
|
|
- teach it to copy in unified kernel images and maybe type #1 boot loader spec entries from host
|
|
- make it operate on loopback files, dissecting enough to find ESP to operate on
|
|
|
|
* Maybe add a separate GPT partition type to the discoverable partition spec
|
|
for "hibernate" partitions, that are exactly like swap partitions but only
|
|
activated right before hibernation and thus never used for regular swapping.
|
|
|
|
* by default, in systemd --user service bump the OOMAdjust to 100, as privs
|
|
allow so that systemd survives
|
|
|
|
* cryptsetup: allow encoding key directly in /etc/crypttab, maybe with a
|
|
"base64:" prefix. Useful in particular for pkcs11 mode.
|
|
|
|
* cryptsetup: reimplement the mkswap/mke2fs in cryptsetup-generator to use
|
|
systemd-makefs.service instead.
|
|
|
|
* socket units: allow creating a udev monitor socket with ListenDevices= or so,
|
|
with matches, then activate app through that passing socket over
|
|
|
|
* unify on openssl (as soon as OpenSSL 3.0 is out, and the Debian license
|
|
confusion is gone)
|
|
- port sd_id128_get_machine_app_specific() over from khash
|
|
- port resolved over from libgcrypt (DNSSEC code)
|
|
- port journald + fsprg over from libgcrypt
|
|
- port importd over from libgcrypt
|
|
- when that's done: kill khash.c
|
|
- when that's done: kill gnutls support in resolved
|
|
|
|
* when we resize disks (homed?) always round up to 4K sectors, not 512K
|
|
|
|
* add growvol and makevol options for /etc/crypttab, similar to
|
|
x-systemd.growfs and x-systemd-makefs.
|
|
|
|
* hook up the TPM to /etc/crypttab, with a new option that is similar to the
|
|
new PKCS#11 option in crypttab, and allows unlocking a LUKS volume via a key
|
|
unsealed from the TPM. Optionally, if TPM is not available fall back to
|
|
TPM-less mode, and set up linear DM mapping instead (inspired by kpartx), so
|
|
that the device paths stay the same, regardless if crypto is used or not.
|
|
|
|
* systemd-repart: by default generate minimized partition tables (i.e. tables
|
|
that only cover the space actually used, excluding any free space at the
|
|
end), in order to maximize dd'ability. Requires libfdisk work, see
|
|
https://github.com/karelzak/util-linux/issues/907
|
|
|
|
* systemd-repart: MBR partition table support. Care needs to be taken regarding
|
|
Type=, so that partition definitions can sanely apply to both the GPT and the
|
|
MBR case. Idea: accept syntax "Type=gpt:home mbr:0x83" for setting the types
|
|
for the two partition types explicitly. And provide an internal mapping so
|
|
that "Type=linux-generic" maps to the right types for both partition tables
|
|
automatically.
|
|
|
|
* systemd-repart: allow sizing partitions as factor of available RAM, so that
|
|
we can reasonably size swap partitions for hibernation.
|
|
|
|
* systemd-repart: allow managing the gpt read-only partition flag + auto-mount flag
|
|
|
|
* systemd-repart: allow boolean option that ensures that if existing partition
|
|
doesn't exist within the configured size bounds the whole command fails. This
|
|
is useful to implement ESP vs. XBOOTLDR schemes in installers: have one set
|
|
of repart files for the case where ESP is large enough and one where it isn't
|
|
and XBOOTLDR is added in instead. Then apply the former first, and if it
|
|
fails to apply use the latter.
|
|
|
|
* systemd-repart: add per-partition option to never reuse existing partition
|
|
and always create anew even if matching partition already exists.
|
|
|
|
* systemd-repart: add per-partition option to fail if partition already exist,
|
|
i.e. is not added new. Similar, add option to fail if partition does not exist yet.
|
|
|
|
* systemd-repart: allow disabling growing of specific partitions, or making
|
|
them (think ESP: we don't ever want to grow it, since we cannot resize vfat)
|
|
|
|
* systemd-repart: make it a static checker during early boot for existence and
|
|
absence of other partitions for trusted boot environments
|
|
|
|
* userdb: allow username prefix searches in varlink API, allow realname and
|
|
realname substr searches in varlink API
|
|
|
|
* userdb: allow uid/gid range checks
|
|
|
|
* userdb: allow existence checks
|
|
|
|
* pid1: activation by journal search expression
|
|
|
|
* when switching root from initrd to host, set the machine_id env var so that
|
|
if the host has no machine ID set yet we continue to use the random one the
|
|
initrd had set.
|
|
|
|
* sd-event: add native support for P_ALL waitid() watching, then move PID 1 to
|
|
it fo reaping assigned but unknown children. This needs to some special care
|
|
to operate somewhat sensibly in light of priorities: P_ALL will return
|
|
arbitrary processes, regardless of the priority we want to watch them with,
|
|
hence on each event loop iteration check all processes which we shall watch
|
|
with higher prio explicitly, and then watch the entire rest with P_ALL.
|
|
|
|
* tweak sd-event's child watching: keep a prioq of children to watch and use
|
|
waitid() only on the children with the highest priority until one is waitable
|
|
and ignore all lower-prio ones from that point on
|
|
|
|
* maybe introduce xattrs that can be set on the root dir of the root fs
|
|
partition that declare the volatility mode to use the image in. Previously I
|
|
thought marking this via GPT partition flags but that's not ideal since
|
|
that's outside of the LUKS encryption/verity verification, and we probably
|
|
shouldn't operate in a volatile mode unless we got told so from a trusted
|
|
source.
|
|
|
|
* figure out automatic partition discovery when combining writable root dir
|
|
with immutable /usr
|
|
|
|
* coredump: maybe when coredumping read a new xattr from /proc/$PID/exe that
|
|
may be used to mark a whole binary as non-coredumpable. Would fix:
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=69447
|
|
|
|
* teach parse_timestamp() timezones like the calendar spec already knows it
|
|
|
|
* beef up hibernation to optionally do swapon/swapoff immediately before/after
|
|
the hibernation
|
|
|
|
* beef up s2h to implement a battery watch loop: instead of entering
|
|
hibernation unconditionally after coming back from resume make a decision
|
|
based on the battery load level: if battery level is above a specific
|
|
threshold, go to suspend again, only hibernate if below it. This means we'd
|
|
stick to suspend usually, but fall back to hibernation only when battery runs
|
|
empty (well, subject to our sampling interval). Related to this, check if we
|
|
can make ACPI _BTP (i.e. /sys/class/power_supply/*/alarm) work for us too,
|
|
i.e. see if it can wake up machines from suspend, so that we could resume
|
|
automatically when the system is low on power and move automatically to
|
|
hibernation mode. (see
|
|
https://uefi.org/sites/default/files/resources/ACPI%206_2_A_Sept29.pdf
|
|
section 10.2.2.8 and
|
|
https://docs.microsoft.com/en-us/windows-hardware/design/device-experiences/modern-standby-wake-sources
|
|
at the end).
|
|
|
|
* add an explicit "vertical" mode to format-table, so that "systemctl
|
|
status"-like outputs (i.e. with a series of field names left and values
|
|
right) become genuine first class citizens, and we gain automatic, sane JSON
|
|
output for them.
|
|
|
|
* We should probably replace /var/log/README, /etc/rc.d/README with symlinks
|
|
that are linked to these places instead of copied. After all they are
|
|
constant vendor data.
|
|
|
|
* maybe add kernel cmdline params: to force random seed crediting
|
|
|
|
* nspawn: on cgroupsv1 issue cgroup empty handler process based on host events,
|
|
so that we make cgroup agent logic safe
|
|
|
|
* nspawn/machined: add API to invoke binary in container, then use that as
|
|
fallback in "machinectl shell"
|
|
|
|
* logind: rework pam_logind to also do a bus call in case of invocation from
|
|
user@.service, which returns the XDG_RUNTIME_DIR value, and make this
|
|
behaviour selectable via pam module option.
|
|
|
|
* homed:
|
|
- when user tries to log into record signed by unrecognized key, automatically add key to our chain after polkit auth
|
|
- rollback when resize fails mid-operation
|
|
- GNOME's side for forget key on suspend (requires rework so that lock screen runs outside of uid)
|
|
- resize on login?
|
|
- shrink fs on logout?
|
|
- update LUKS password on login if we find there's a password that unlocks the JSON record but not the LUKS device.
|
|
- create on activate?
|
|
- properties: icon url?, preferred session type?, administrator bool (which translates to 'wheel' membership)?, address?, telephone?, vcard?, samba stuff?, parental controls?
|
|
- communicate clearly when usb stick is safe to remove. probably involves
|
|
beefing up logind to make pam session close hook synchronous and wait until
|
|
systemd --user is shut down.
|
|
- logind: maybe keep a "busy fd" as long as there's a non-released session around or the user@.service
|
|
- maybe make automatic, read-only, time-based reflink-copies of LUKS disk
|
|
images (and btrfs snapshots of subvolumes) (think: time machine)
|
|
- distinguish destroy / remove (i.e. currently we can unregister a user, unregister+remove their home directory, but not just remove their home directory)
|
|
- in systemd's PAMName= logic: query passwords with ssh-askpassword, so that we can make "loginctl set-linger" mode work
|
|
- fingerprint authentication, pattern authentication, …
|
|
- make sure "classic" user records can also be managed by homed
|
|
- make size of $XDG_RUNTIME_DIR configurable in user record
|
|
- query password from kernel keyring first
|
|
- update even if record is "absent"
|
|
- add a "access mode" + "fstype" field to the "status" section of json identity records reflecting the actually used access mode and fstype, even on non-luks backends
|
|
- move acct mgmt stuff from pam_systemd_home to pam_systemd?
|
|
- when "homectl --pkcs11-token-uri=" is used, synthesize ssh-authorized-keys records for all keys we have private keys on the stick for
|
|
- make slice for users configurable (requires logind rework)
|
|
- logind: populate auto-login list bus property from PKCS#11 token
|
|
- when determining state of a LUKS home directory, check DM suspended sysfs file
|
|
- introduce API for "making room", that grows/shrinks home directory
|
|
according to elastic parameters, discards blocks, and removes additional snapshots. Call it
|
|
either from UI when disk space gets low
|
|
|
|
* introduce a new per-process uuid, similar to the boot id, the machine id, the
|
|
invocation id, that is derived from process creds, specifically a hashed
|
|
combination of AT_RANDOM + getpid() + the starttime from
|
|
/proc/self/status. Then add these ids implicitly when logging. Deriving this
|
|
uuid from these three things has the benefit that it can be derived easily
|
|
from /proc/$PID/ in a stable, and unique way that changes on both fork() and
|
|
exec().
|
|
|
|
* let's not GC a unit while its ratelimits are still pending
|
|
|
|
* when killing due to service watchdog timeout maybe detect whether target
|
|
process is under ptracing and then log loudly and continue instead.
|
|
|
|
* introduce a new group to own TPM devices
|
|
|
|
* make rfkill uaccess controllable by default, i.e. steal rule from
|
|
gnome-bluetooth and friends
|
|
|
|
* tweak journald context caching. In addition to caching per-process attributes
|
|
keyed by PID, cache per-cgroup attributes (i.e. the various xattrs we read)
|
|
keyed by cgroup path, and guarded by ctime changes. This should provide us
|
|
with a nice speed-up on services that have many processes running in the same
|
|
cgroup.
|
|
|
|
* make MAINPID= message reception checks even stricter: if service uses User=,
|
|
then check sending UID and ignore message if it doesn't match the user or
|
|
root.
|
|
|
|
* maybe trigger a uevent "change" on a device if "systemctl reload xyz.device"
|
|
is issued.
|
|
|
|
* when importing an fs tree with machined, optionally apply userns-rec-chown
|
|
|
|
* when importing an fs tree with machined, complain if image is not an OS
|
|
|
|
* Maybe introduce a helper safe_exec() or so, which is to execve() which
|
|
safe_fork() is to fork(). And then make revert the RLIMIT_NOFILE soft limit
|
|
to 1K implicitly, unless explicitly opted-out.
|
|
|
|
* rework seccomp/nnp logic that even if User= is used in combination with
|
|
a seccomp option we don't have to set NNP. For that, change uid first whil
|
|
keeping CAP_SYS_ADMIN, then apply seccomp, the drop cap.
|
|
|
|
* add a concept for automatically loading per-unit secrets off disk and
|
|
inserting them into the kernel keyring. Maybe SecretsDirectory= similar to
|
|
ConfigurationDirectory=.
|
|
|
|
* when no locale is configured, default to UEFI's PlatformLang variable
|
|
|
|
* bootctl,sd-boot: actually honour the "architecture" key
|
|
|
|
* add a new syscall group "@esoteric" for more esoteric stuff such as bpf() and
|
|
usefaultd() and make systemd-analyze check for it.
|
|
|
|
* paranoia: whenever we process passwords, call mlock() on the memory
|
|
first. i.e. look for all places we use free_and_erasep() and
|
|
augment them with mlock(). Also use MADV_DONTDUMP.
|
|
|
|
* Move RestrictAddressFamily= to the new cgroup create socket
|
|
|
|
* support the bind/connect/sendmsg cgroup stuff for sandboxing, and possibly
|
|
patching around
|
|
|
|
* maybe implicitly attach monotonic+realtime timestamps to outgoing messages in
|
|
log.c and sd-journal-send
|
|
|
|
* optionally: turn on cgroup delegation for per-session scope units
|
|
|
|
* introduce per-unit (i.e. per-slice, per-service) journal log size limits.
|
|
|
|
* sd-boot: automatically load EFI modules from some drop-in dir, so that people
|
|
can add in file system drivers and such
|
|
|
|
* sd-boot: optionally, show boot menu when previous default boot item has
|
|
non-zero "tries done" count
|
|
|
|
* introduce an option (or replacement) for "systemctl show" that outputs all
|
|
properties as JSON, similar to busctl's new JSON output. In contrast to that
|
|
it should skip the variant type string though.
|
|
|
|
* augment CODE_FILE=, CODE_LINE= with something like CODE_BASE= or so which
|
|
contains some identifier for the project, which allows us to include
|
|
clickable links to source files generating these log messages. The identifier
|
|
could be some abberviated URL prefix or so (taking inspiration from Go
|
|
imports). For example, for systemd we could use
|
|
CODE_BASE=github.com/systemd/systemd/blob/98b0b1123cc or so which is
|
|
sufficient to build a link by prefixing "http://" and suffixing the
|
|
CODE_FILE.
|
|
|
|
* Augment MESSAGE_ID with MESSAGE_BASE, in a similar fashion so that we can
|
|
make clickable links from log messages carrying a MESSAGE_ID, that lead to
|
|
some explanatory text online.
|
|
|
|
* maybe extend .path units to expose fanotify() per-mount change events
|
|
|
|
* Add a "systemctl list-units --by-slice" mode or so, which rearranges the
|
|
output of "systemctl list-units" slightly by showing the tree structure of
|
|
the slices, and the units attached to them.
|
|
|
|
* the a-posteriori stopping of units bound to units that disappeared logic
|
|
should be reworked: there should be a queue of units, and we should only
|
|
enqueue stop jobs from a defer event that processes queue instead of
|
|
right-away when we find a unit that is bound to one that doesn't exist
|
|
anymore. (similar to how the stop-unneeded queue has been reworked the same
|
|
way)
|
|
|
|
* nspawn: make nspawn suitable for shell pipelines: instead of triggering a
|
|
hangup when input is finished, send ^D, which synthesizes an EOF. Then wait
|
|
for hangup or ^D before passing on the EOF.
|
|
|
|
* When reloading configuration PID 1 should reset all its properties to the
|
|
original defaults before calling parse_config()
|
|
|
|
* nspawn: greater control over selinux label?
|
|
|
|
* hibernate/s2h: make this robust and safe to enable in Fedora by default.
|
|
Specifically:
|
|
|
|
1. add resume_offset support to the resume code (i.e. support swap files
|
|
properly)
|
|
2. check if swap is on weird storage and refuse if so
|
|
3. add auto-detection of hibernation images
|
|
|
|
* 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.
|
|
|
|
* 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 disaster. 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, 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.
|
|
|
|
* 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 the 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 fall back to read-only bind mounting the file instead.
|
|
|
|
* show invocation ID in systemd-run output
|
|
|
|
* bypass SIGTERM state in unit files if KillSignal is SIGKILL
|
|
|
|
* 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.
|
|
|
|
* sd-bus: add vtable flag, that may be used to request client creds implicitly
|
|
and asynchronously before dispatching the operation
|
|
|
|
* sd-bus: parse addresses given in sd_bus_set_addresses immediately and not
|
|
only when used. Add unit tests.
|
|
|
|
* 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 RootDirectoryStartOnly= in favour of a new ExecStart= prefix char
|
|
|
|
* 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
|
|
|
|
* 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
|
|
|
|
* maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
|
|
the quota of 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=.
|
|
|
|
* 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.
|
|
|
|
* expose IO accounting data on the bus, show it in systemd-run --wait and log
|
|
about it in the resource log message
|
|
|
|
* show whether a service has out-of-date configuration in "systemctl status" by
|
|
using mtime data of ConfigurationDirectory=.
|
|
|
|
* 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
|
|
|
|
* 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.
|
|
|
|
* 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
|
|
|
|
* 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
|
|
|
|
* 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
|
|
|
|
* 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
|
|
|
|
* 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...
|
|
|
|
* 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
|
|
|
|
* 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 example, 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
|
|
|
|
* 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
|
|
|
|
* 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
|
|
|
|
* 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=
|
|
|
|
* 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)
|
|
|
|
* systemctl: if some operation fails, show log output?
|
|
|
|
* 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....
|
|
|
|
* 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
|
|
|
|
* 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=
|
|
|
|
* cgroups:
|
|
- implement per-slice CPUFairScheduling=1 switch
|
|
- 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
|
|
|
|
* 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
|
|
|
|
* 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 support iouring as backend, so that we allow hooking read and write
|
|
operations instead of IO ready events into event loops. See considerations
|
|
here:
|
|
http://blog.vmsplice.net/2020/07/rethinking-event-loop-integration-for.html
|
|
|
|
* 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
|
|
|
|
* 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})
|
|
|
|
* Add ConditionDirectoryNotEmpty= handle non-absoute paths as a search path or add
|
|
ConditionConfigSearchPathNotEmpty= or different syntax? See the discussion starting at
|
|
https://github.com/systemd/systemd/pull/15109#issuecomment-607740136.
|
|
|
|
* 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
|
|
* bootctl
|
|
- recognize the case when not booted on EFI
|
|
|
|
* 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
|
|
- logind: wakelock/opportunistic suspend support
|
|
- Add pretty name for seats in logind
|
|
- logind: allow showing logout dialog from system?
|
|
- 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
|
|
- (optionally?) spawn seat-manager@$SEAT.service whenever a seat shows up that as CanGraphical set
|
|
|
|
* journal:
|
|
- consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
|
|
- 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.
|
|
- fall back 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 already after a short timeout
|
|
- 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() in the header,
|
|
so it is possible to display when the file was last synced.
|
|
- journal-send.c, log.c: when the log socket is clogged, and we drop, count this and write a message about this when it gets unclogged again.
|
|
- journal: find a way to allow dropping history early, based on priority, other rules
|
|
- journal: When used on NFS, check payload hashes
|
|
- journald: add kernel cmdline option to disable ratelimiting for debug purposes
|
|
- refuse taking lower-case variable names in sd_journal_send() and friends.
|
|
- journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
|
|
- journal: deal nicely with byte-by-byte copied files, especially regards header
|
|
- journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
|
|
- Replace utmp, wtmp, btmp, and lastlog completely with journal
|
|
- journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
|
|
- when a kernel driver logs in a tight loop, we should ratelimit that too.
|
|
- journald: optionally, log debug messages to /run but everything else to /var
|
|
- journald: when we drop syslog messages because the syslog socket is
|
|
full, make sure to write how many messages are lost as first thing
|
|
to syslog when it works again.
|
|
- journald: 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
|
|
- check if loop in decompress_blob_xz() is necessary
|
|
|
|
* 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,
|
|
- in particular an example how to do the equivalent of switching runlevels
|
|
- man: maybe sort directives in man pages, and take sections from --help and apply them to man too
|
|
- document root=gpt-auto properly
|
|
|
|
* 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 DST changes
|
|
- Modulate timer frequency based on battery state
|
|
|
|
* add libsystemd-password or so to query passwords during boot using the password agent logic
|
|
|
|
* clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
|
|
|
|
* on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
|
|
|
|
* make repeated alt-ctrl-del presses printing a dump
|
|
|
|
* hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
|
|
|
|
* currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
|
|
|
|
* nspawn:
|
|
- emulate /dev/kmsg using CUSE and turn off the syslog syscall
|
|
with seccomp. That should provide us with a useful log buffer that
|
|
systemd can log to during early boot, and disconnect container logs
|
|
from the kernel's logs.
|
|
- as soon as networkd has a bus interface, hook up --network-interface=,
|
|
--network-bridge= with networkd, to trigger netdev creation should an
|
|
interface be missing
|
|
- a nice way to boot up without machine id set, so that it is set at boot
|
|
automatically for supporting --ephemeral. Maybe hash the host machine id
|
|
together with the machine name to generate the machine id for the container
|
|
- fix logic always print a final newline on output.
|
|
https://github.com/systemd/systemd/pull/272#issuecomment-113153176
|
|
- should optionally support receiving WATCHDOG=1 messages from its payload
|
|
PID 1...
|
|
- optionally automatically add FORWARD rules to iptables whenever nspawn is
|
|
running, remove them when shut down.
|
|
|
|
* 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 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
|
|
|
|
* 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)
|
|
|
|
* 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)
|
|
- 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
|
|
- 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
|
|
- add verification of [Install] section to systemd-analyze verify
|
|
|
|
* 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
|
|
|
|
* 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 reduced [Link] support to .network files
|
|
- properly handle routerless dhcp leases
|
|
- work with non-Ethernet devices
|
|
- 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
|
|
- option 12, hostname 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)
|
|
- whenever uplink info changes, make DHCP server send out FORCERENEW
|
|
|
|
* Figure out how to do unittests of networkd's state serialization
|
|
|
|
* 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
|
|
|
|
* make cryptsetup lower --iter-time
|
|
|
|
* kernel: add device_type = "fb", "fbcon" to class "graphics"
|
|
|
|
* /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=
|
|
|
|
* 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
|
|
|
|
* systemctl status should know about 'systemd-analyze calendar ... --iterations='
|
|
* If timer has just OnInactiveSec=..., it should fire after a specified time
|
|
after being started.
|
|
|
|
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
