Features:
-* when we fork off generators and such, lower LIMIT_NOFILE soft limit to 1K
+* 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 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=.
-* 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
* 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 cgroup v2 for all leaf cgroups (kernel v4.19+)
-* set memory.oom.group in cgroupsv2 for all leaf cgroups (kernel v4.19+)
-
-* drop umask() calls and suchlike from our generators, pid1 should set things up correctly anyway
+* 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 string_erase()/string_free_erase() and
* 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:
* 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
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
state.

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

-
* 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
* 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
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
