An incoming connection that is immediately terminated might result in getpeername() or a similar call failing. Hence it is quite possible that while we are setting up an instantiated service for a socket we might get an error and we shouldn't take this as hint to take the listening socket down. https://bugs.freedesktop.org/show_bug.cgi?id=45297 https://bugzilla.novell.com/show_bug.cgi?id=741590

Bugfixes:
|
|
|
|
* swap units that are activated by one name but shown in the kernel under another are semi-broken
|
|
|
|
* make anaconda write timeout=0 for encrypted devices
|
|
|
|
* service: pid file reading after reload doesn't work, since we don't reset the pid variable
|
|
|
|
* make sure timeouts are applied to Type=oneshot services.
|
|
|
|
* Dangling symlinks of .automount unit files in .wants/ directories, set up
|
|
automount points even when the original .automount file did not exist
|
|
anymore. Only the .mount unit was still around.
|
|
|
|
* make polkit checks async
|
|
|
|
* properly handle .mount unit state tracking when two mount points are stacked one on top of another on the exact same mount point.
|
|
|
|

|
|
|
|
* make logind reserve tty10 or so for text logins, so that gdm never picks it up

|
|
|
|
* isolate for getty is still broken, due to logind
|
|
|
|
* default unix qlen is too small (10). bump sysctl? add sockopt?

|
|
currently ignored because it is empty before the generatores are executed
|
|
|
|
* Possibly, detect whether SysV init scripts can do reloading by looking for "echo Usage:" lines
|
|
|
|
* figure out whether we should leave dbus around during shutdown

|
|
|
|
* add interface to allow immediate rotation of the journal, and even flushing.
|
|
|
|

|
|
|
|

|
|
|
* move to LGPL2+
|
|
|
|
* logind: allow showing logout dialog from system
|
|
|
|
* document that %% can be used to write % in a string that is specifier extended
|

|
|
|
* unset container= in PID1?
|
|
|
|
* automatically escape unit names passed on the service (i.e. think "systemctl start serial-getty.service@serial/by-path/jshdfjsdfhkjh" being automatically escaped as necessary.
|
|
|
|
* if we can not get user quota for tmpfs, mount a separate tmpfs instance
|
|
for every user in /run/user/$USER with a configured maximum size
|
|
|
|
* default to actual 32bit PIDs, via /proc/sys/kernel/pid_max
|
|
|
|
* add an option to make mounts private/shareable and so on, enable this for root by default
|
|
|
|
* be able to specify a forced restart of service A where service B depends on, in case B

|
needs to be auto-respawned?
|
|

|
|
|
* don't set $HOME in services unless requested
|

|
|
|
|
* logind: spawn user@..service on login
|
|
|
|
* logind: non-local X11 server handling
|
|
|
|
* implement Register= switch in .socket units to enable registration
|
|
in Avahi, RPC and other socket registration services.
|
|
|
|
* make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
|
|
|
|
* readahead: use BTRFS_IOC_DEFRAG_RANGE instead of BTRFS_IOC_DEFRAG ioctl, with START_IO
|
|
|
|
* readahead: check whether a btrfs volume includes ssd by checking mount flag "ssd"
|
|
|
|
* support sd_notify() style notification when reload begins (RELOADING=1), reload is finished (READY=1), and add ReloadSignal= then to use in combination
|
|
|
|
* support sd_notify() style notification when shutting down, to make auto-exit bus services work (STOPPING=1)
|
|
|
|
* 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.
|
|
|

PR_SET_CHILD_REAPER patch: https://lkml.org/lkml/2011/7/28/426
|
|
|
|
* fix alsa mixer restore to not print error when no config is stored
|
|
|
|
* udisks should not use udisks-part-id, instead use blkid. also not probe /dev/loopxxx
|
|
|
|
* snd-seq should go, https://bugzilla.redhat.com/show_bug.cgi?id=676095
|
|
|
|
* gnome-shell python script/glxinfo/is-accelerated must die
|
|
|
|
* make cryptsetup lower --iter-time
|
|
|
|
* patch kernel for xattr support in /dev, /proc/, /sys and /sys/fs/cgroup?
|
|
|
|
* NTP: the kernel's 11-minutes-mode syncs the system time to the RTC, but only
|
|
in an ~30 minutes window. It does not adjust larger differences. Find a way
|
|
to tell the kernel, to always do a full time sync when the RTC is in UTC and
|
|
we are in 11-minutes-mode. When we trust the system time to NTP we also want
|
|
the RTC to sync up.
|
|
|
|
* patch kernel for cpu feature modalias for autoloading aes/kvm/...
|
|
(patches in linux-next, on the way to the next kernel)
|
|
|
|
* kernel: add /proc/sys file exposing CAP_LAST_CAP? sysconf?
|
|
merged: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=73efc0394e148d0e15583e13712637831f926720
|
|
|
|
* kernel: add device_type = "fb", "fbcon" to class "graphics"
|
|
|
|
Regularly:
|
|
|
|
* look for close() vs. close_nointr() vs. close_nointr_nofail()
|
|
|
|
* check for strerror(r) instead of strerror(-r)
|
|
|
|
* Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel
|
|
|
|
* %m in printf() instead of strerror();
|
|
|
|
* pahole
|
|
|
|
* set_put(), hashmap_put() return values check. i.e. == 0 doesn't free()!
