Bugfixes:
-* copy.c: set the right chattrs before copying files and others after
-
* 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.
-* Clarify what IPAddress* matches (source, destination, both?)
-
External:
* Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
Features:
+* 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.
+
+* clean up sleep.c:
+ - Use CLOCK_BOOTTIME_ALARM for waking up s2h instead of RTC ioctls
+ - Parse sleep.conf only once, and parse its whole contents so that we don't
+ have to parse it again and again in s2h
+ - Make sure resume= and resume_offset= on the kernel cmdline always take
+ precedence
+
+* maybe add a seccomp-based high-level filter that blocks creation of suid/sgid
+ files.
+
* 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.
* when importing an fs tree with machined, complain if image is not an OS
-* when we fork off generators and such, lower LIMIT_NOFILE soft limit to 1K
-
* 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.
inserting them into the kernel keyring. Maybe SecretsDirectory= similar to
ConfigurationDirectory=.
-* systemd-gpt-auto: if we find the root dir mounted read-only and the gpt flag
- doesn't say so generate job that remounts it writable
-
* when no locale is configured, default to UEFI's PlatformLang variable
* When logind.conf contains HandleLidSwitch=suspend-then-hibernate and we can't
hibernate because the swap partition isn't large enough, still suspend
-* bootctl: implement Type #2 boot loader entry discovery
-
* bootctl,sd-boot: actually honour the "architecture" key
-* when a socket unit is spawned with an AF_UNIX path in /var/run, complain and
- patch it to use /run instead
-
-* consider splitting out all temporary file creation APIs (we have so many in
- fileio.h and elsewhere!) into a new util file of its own.
-
-* set memory.oom.group in cgroupsv2 for all leaf cgroups (kernel v4.19+)
+* set memory.oom.group in cgroup v2 for all leaf cgroups (kernel v4.19+)
* add a new syscall group "@esoteric" for more esoteric stuff such as bpf() and
usefaultd() and make systemd-analyze check for it.
-* drop umask() calls and suchlike from our generators, pid1 should set things up correctly anyway
-
* paranoia: whenever we process passwords, call mlock() on the memory
first. i.e. look for all places we use string_erase()/string_free_erase() and
- augment them with mlock()
+ augment them with mlock(). Also use MADV_DONTDUMP
* whenever oom_kill memory.event event is triggered print a nice log message
* maybe implicitly attach monotonic+realtime timestamps to outgoing messages in
log.c and sd-journal-send
-* chown() tty a service is attached to after the service goes down
-
* optionally: turn on cgroup delegation for per-session scope units
* introduce per-unit (i.e. per-slice, per-service) journal log size limits.
show state of these flags, and optionally trigger such a factory reset on
next boot by setting the flag.
-* sd-boot: search drop-ins in $BOOT, too
-
-* sd-boot: add "oneshot boot timeout" variable support
-
* sd-boot: automatically load EFI modules from some drop-in dir, so that people
can add in file system drivers and such
-* esp generator: also mount $BOOT if found
-
* sd-boot: optionally, show boot menu when previous default boot item has
non-zero "tries done" count
-* logind: add "boot into bootmenu" API, and possibly even "boot into windows"
- and "boot into macos".
-
-* bootspec.c: also enumerate EFI unified kernel images.
-
* maybe set a special xattr on cgroups that have delegate=yes set, to make it
easy to mark cut points
* 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.
-
* hibernate/s2h: make this robust and safe to enable in Fedora by default.
Specifically:
* support projid-based quota in machinectl for containers
-* 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.
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.
* 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()
+* replace all remaining 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
* 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
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
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
* 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
* 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
- 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
+ - verify that the files boot entries point to exist
+ - recognize the case when not booted on EFI
+ - specify paths for boot entries
* maybe do not install getty@tty1.service symlink in /etc but in /usr?
- 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
- 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
+ - document root=gpt-auto properly
* systemctl:
- add systemctl switch to dump transaction without executing it
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
* use secure_getenv() instead of getenv() where appropriate
* link up selected blog stories from man pages and unit files Documentation= fields
+String is not UTF-8 clean, ignoring assignment
+ timedatex.service: Consumed 26ms CPU time.
