   1 Bugfixes:
   2
   3 * swap units that are activated by one name but shown in the kernel under another are semi-broken
   4
   5 * NM should pull in network.target (PENDING)
   6   https://bugzilla.redhat.com/show_bug.cgi?id=692008
   7
   8 * make anaconda write timeout=0 for encrypted devices
   9
  10 * service: pid file reading after reload doesn't work, since we don't reset the pid variable
  11
  12 * make sure timeouts are applied to Type=oneshot services.
  13
  14 * Dangling symlinks of .automount unit files in .wants/ directories, set up
  15   automount points even when the original .automount file did not exist
  16   anymore. Only the .mount unit was still around.
  17
  18 * make polkit checks async
  19
  20 * properly handle .mount unit state tracking when two mount points are stacked one on top of another on the exact same mount point.
  21
  22 Features:
  23
  24 * journald: reuse XZ context
  25
  26 * logind: add equivalent to sd_pid_get_owner_uid() to the D-Bus API
  27
  28 * Fedora: disable journald's /proc/kmsg reading on Fedora for now
  29
  30 * avoid that we choke on journal coredump loops (i.e. where the journal crashes and causes a coredump to be fed back to it)
  31
  32 * write RPM spec macros for presets
  33
  34 * write man pages for systemd-cgtop, systemd-cat
  35
  36 * journal: write man pages for API
  37
  38 * journal: OR matches are borked
  39
  40 * journal: extend hash tables as we go
  41
  42 * journal: API for looking for retrieving "all values of this field"
  43
  44 * journal: deal nicely with byte-by-byte copied files, especially regards header
  45
  46 * journal: local deserializer of export mode, http server
  47
  48 * journal: message catalog
  49
  50 * journal: forward-secure signatures
  51
  52 * document the exit codes when services fail before they are exec()ed
  53
  54 * rework namespace support, don't use pivot_root, and mount things after creating the namespace, not before
  55
  56 * systemctl journal command
  57
  58 * journalctl: --cursor support, priority filtering
  59
  60 * systemctl status: show coredumps
  61
  62 * systemctl status: show whether journal was rotated since service started
  63
  64 * save coredump in Windows/Mozilla minidump format
  65
  66 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
  67
  68 * allow per-entry control on /var vs. /run (think incognito browser mode)
  69
  70 * clean up session cgroups that remain after logout (think sshd), but eventually run empty
  71
  72 * support "systemctl stop foobar@.service" to stop all units matching a certain template
  73
  74 * move to LGPL2+
  75
  76 * logind: selinux is borked...
  77
  78 * logind: allow showing logout dialog from system
  79
  80 * document that %% can be used to write % in a string that is specifier extended
  81
  82 * check utf8 everywhere
  83
  84 * when an instanced service exits, remove its parent cgroup too if possible.
  85
  86 * Make libselinux, libattr, libcap, libdl dependencies only of the tools which actually need them.
  87
  88 * as Tom Gundersen pointed out there's a always a dep loop if people use crypto file systems with random keys
  89
  90 * unset container= in PID1?
  91
  92 * 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.
  93
  94 * if we can not get user quota for tmpfs, mount a separate tmpfs instance
  95   for every user in /run/user/$USER with a configured maximum size
  96
  97 * default to actual 32bit PIDs, via /proc/sys/kernel/pid_max
  98
  99 * add an option to make mounts private/shareable and so on, enable this for root by default
 100
 101 * internal restart counter for units (focus on auto-respawn)
 102
 103 * finer-grained auto-respawn settings (rate-limit)
 104
 105 * be able to specify a forced restart of service A where service B depends on, in case B
 106   needs to be auto-respawned?
 107
 108 * Something is wrong with symlink handling of "autovt@.service" in "systemctl list-unit-files"
 109
 110 * when a bus name of a service disappears from the bus make sure to queue further activation requests
 111
 112 * something like ConditionExec= or ExecStartPre= without failure state
 113
 114 * service restart retry configuration
 115
 116 * tmpfiles: apply "x" on "D" too (see patch from William Douglas)
 117
 118 * don't set $HOME in services unless requested
 119
 120 * hide PAM/TCPWrap options in fragment parser when compile time disabled
 121
 122 * when we automatically restart a service, ensure we retsart its rdeps, too.
 123
 124 * allow Type=simple with PIDFile=
 125   https://bugzilla.redhat.com/show_bug.cgi?id=723942
 126
 127 * move PAM code into its own binary
 128
 129 * warn if the user stops a service but not its associated socket
 130
 131 * logind: spawn user@..service on login
 132
 133 * logind: non-local X11 server handling
 134
 135 * implement Register= switch in .socket units to enable registration
 136   in Avahi, RPC and other socket registration services.
 137
 138 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
 139
 140 * readahead: use BTRFS_IOC_DEFRAG_RANGE instead of BTRFS_IOC_DEFRAG ioctl, with START_IO
 141
 142 * readahead: check whether a btrfs volume includes ssd by checking mount flag "ssd"
 143
 144 * support sd_notify() style notification when reload begins (RELOADING=1), reload is finished (READY=1), and add ReloadSignal= then to use in combination
 145
 146 * support sd_notify() style notification when shutting down, to make auto-exit bus services work (STOPPING=1)
 147
 148 * verify that the AF_UNIX sockets of a service in the fs still exist
 149   when we start a service in order to avoid confusion when a user
 150   assumes starting a service is enough to make it accessible
 151
 152 * Make it possible to set the keymap independently from the font on
 153   the kernel cmdline. Right now setting one resets also the other.
 154
 155 * move nss-myhostname into systemd
 156
 157 * and a dbus call to generate target from current state
 158
 159 * drop /.readahead on bigger upgrades with yum
 160
 161 * add inode nr check to readahead to suppress preloading changed files

 163 * add support for /bin/mount -s
 164
 165 * GC unreferenced jobs (such as .device jobs)
 166
 167 * cgroup_notify_empty(): recursively check groups up the tree, too
 168
 169 * when failing to start a service due to ratelimiting, try again later, if restart=always is set
 170
 171 * write blog stories about:
 172   - enabling dbus services
 173   - status update
 174   - how to make changes to sysctl and sysfs attributes
 175   - remote access
 176   - how to pass throw-away units to systemd, or dynamically change properties of existing units
 177   - how to integrate cgconfig and suchlike with systemd
 178
 179 * allow port=0 in .socket units
 180
 181 * move readahead files into /var, look for them with .path units
 182
 183 * teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
 184
 185 * support systemd.mask= on the kernel command line.
 186
 187 * when key file cannot be found, read it from kbd in cryptsetup

 190
 191 * recreate systemd's D-Bus private socket file on SIGUSR2
 192
 193 * Support --test based on current system state

 199 * configurable jitter for timer events
 200
 201 * timer events with system resume

 204
 205 * dot output for --test showing the 'initial transaction'
 206
 207 * calendar time support in timer, iCalendar semantics for the timer stuff (RFC2445)
 208     http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=99ee5315dac6211e972fa3f23bcc9a0343ff58c4
 209
 210 * implicitly import "defaults" settings file into all types
 211 * exec settings override
 212 * writable cgroups dbus properties for live changes
 213
 214 * read config fragments for all units from /lib/systemd/system/foobar.service.d/ to override/extend specific settings
 215
 216 * port over to LISTEN_FDS/LISTEN_PID:
 217    - rpcbind (/var/run/rpcbind.sock!) HAVEPATCH
 218    - cups     HAVEPATCH
 219    - postfix, saslauthd
 220    - apache/samba

 232
 233 * systemctl list-jobs - show dependencies
 234
 235 * add systemctl switch to dump transaction without executing it
 236
 237 * suspend, resume support?
 238
 239 * drop cap bounding set in readahead and other services
 240
 241 External:
 242
 243 * dbus:
 244    - get process transport into dbus for systemctl -P/-H (PENDING)
 245    - dbus --user
 246    - natively watch for dbus-*.service symlinks (PENDING)
 247    - allow specification of socket mode/umask when allocating DBusServer
 248    - allow disabling of fd passing when connecting a AF_UNIX connection
 249    - allow disabling of UID passing for AUTH EXTERNAL
 250
 251 * systemd --user
 252     PR_SET_CHILD_REAPER patch: https://lkml.org/lkml/2011/7/28/426
 253
 254 * fix alsa mixer restore to not print error when no config is stored
 255
 256 * udisks should not use udisks-part-id, instead use blkid. also not probe /dev/loopxxx
 257
 258 * snd-seq should go, https://bugzilla.redhat.com/show_bug.cgi?id=676095
 259
 260 * gnome-shell python script/glxinfo/is-accelerated must die
 261
 262 * make cryptsetup lower --iter-time
 263
 264 * patch kernel for xattr support in /dev, /proc/, /sys and /sys/fs/cgroup?
 265
 266 * NTP: the kernel's 11-minutes-mode syncs the system time to the RTC, but only
 267   in an ~30 minutes window. It does not adjust larger differences. Find a way
 268   to tell the kernel, to always do a full time sync when the RTC is in UTC and
 269   we are in 11-minutes-mode. When we trust the system time to NTP we also want
 270   the RTC to sync up.
 271
 272 * patch kernel for cpu feature modalias for autoloading aes/kvm/...
 273     (patches in linux-next, on the way to the next kernel)
 274
 275 * kernel: add /proc/sys file exposing CAP_LAST_CAP? sysconf?
 276     merged: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=73efc0394e148d0e15583e13712637831f926720
 277
 278 * kernel: add device_type = "fb", "fbcon" to class "graphics"
 279
 280 Regularly:
 281
 282 * look for close() vs. close_nointr() vs. close_nointr_nofail()
 283
 284 * check for strerror(r) instead of strerror(-r)
 285
 286 * Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel
 287
 288 * %m in printf() instead of strerror();
 289
 290 * pahole
 291
 292 * set_put(), hashmap_put() return values check. i.e. == 0 doesn't free()!
