2014-12-09journal: optimize iteration: skip files that cannot improve current ↵Michal Schmidt
candidate entry Suppose that while iterating we have already looked into a journal file and got a candidate for the next entry. And we are considering to look into another journal file because it may contain an entry that is nearer to the current location than the candidate. We should skip the whole journal file if we can tell by looking at its header that none of its entries can precede the candidate. Before: $ time ./journalctl --since=2014-06-01 --until=2014-07-01 > /dev/null real 0m20.518s user 0m19.989s sys 0m0.328s After: $ time ./journalctl --since=2014-06-01 --until=2014-07-01 > /dev/null real 0m9.445s user 0m9.228s sys 0m0.213s
2014-12-09journal: optimize iteration: skip whole files behind current locationMichal Schmidt
Interleaving of entries from many journal files is expensive. But there is room for optimization. We can skip looking into journal files whose entries all lie before the current iterating location. We can tell if that's the case from looking at the journal file header. This saves a huge amount of work if one has many of mostly not interleaved journal files. On my workstation with 90 journal files in /var/log/journal/ID/ totalling 3.4 GB I get these results: Before: $ time ./journalctl --since=2014-06-01 --until=2014-07-01 > /dev/null real 5m54.258s user 2m4.263s sys 3m48.965s After: $ time ./journalctl --since=2014-06-01 --until=2014-07-01 > /dev/null real 0m20.518s user 0m19.989s sys 0m0.328s The high "sys" time in the original was caused by putting more stress on the mmap-cache than it could handle. With the patch the working set now consists of fewer mmap windows and mmap-cache is not thrashing.

2014-12-09unit: update unit dropin paths and time when dropin file is written.WaLyong Cho
If a unit is set property by "systemctl set-property", a new dropin file is generated. But the unit's dropin_paths and dropin_mtime are not updated. So the unit is shown as need daemon reload. Update unit dropin_paths and dropin_mtime also when dropin file is written.
2014-12-09bus-proxy: cloning smack labelPrzemyslaw Kedzierski
When dbus client connects to systemd-bus-proxyd through Unix domain socket proxy takes client's smack label and sets for itself. It is done before and independent of dropping privileges. The reason of such soluton is fact that tests of access rights performed by lsm may take place inside kernel, not only in userspace of recipient of message. The bus-proxyd needs CAP_MAC_ADMIN to manipulate its label. In case of systemd running in system mode, CAP_MAC_ADMIN should be added to CapabilityBoundingSet in service file of bus-proxyd. In case of systemd running in user mode ('systemd --user') it can be achieved by addition Capabilities=cap_mac_admin=i and SecureBits=keep-caps to user@.service file and setting cap_mac_admin+ei on bus-proxyd binary.
2014-12-09run: introduce timer support optionWaLyong Cho
Support timer options --on-active=, --on-boot=, --on-startup=, --on-unit-active=, --on-unit-inactive=, --on-calendar=. Each options corresponding with OnActiveSec=, OnBootSec=, OnStartupSec=, OnUnitActiveSec=, OnUnitInactiveSec=, OnCalendar= of timer respectively. And OnCalendar= and WakeSystem= supported by --timer-property= option like --property= of systemd-run. And if --unit= option and timer options are specified the command can be omitted. In this case, systemd-run assumes the target service is already loaded. And just try to generate transient timer unit only.

2014-12-09bus: sync with kdbus-git (ABI break)David Herrmann
kdbus-git gained two new features: * memfd offsets: This allows to specify a 'start' offset in kdbus_memfd so you can send partial memfd hunks instead of always the full memfd * KDBUS_HELLO_UNPRIVILEGED: If passed during HELLO, the client will be treated as unprivileged.

2014-12-09cgroup: Handle error when destroying cgroupRoss Lagerwall
If a cgroup fails to be destroyed (most likely because there are still processes running as part of a service after the main pid exits), don't free and remove the cgroup unit from the manager. This fixes a regression introduced by the cgroup rework in v205 where systemd would forget about processes still running after the unit becomes inactive. (This can happen when the main pid exits and KillMode=process or none).
2014-12-09fstab-generator: Allow mount.usr without mount.usrflags, honor rw/roMichael Marineau
There is no need to require mount.usrflags. The original implementation assumed that a btrfs subvolume would always be needed but that is not applicable to systems that do not use btrfs for /usr. Similar to using rootflags= for the default of mount.usrflags=, append the classic 'ro' and 'rw' flags to the mount options.

2014-12-08sd-bus: rework ELF error mapping table magicLennart Poettering
The ELF magic cannot work for consumers of our shard library, since they are in a different module. Hence make all the ELF magic private, and instead introduce a public function to register additional static mapping table.

2014-12-04tmpfiles, man: Add xattr support to tmpfilesMaciej Wereski
This patch makes it possible to set extended attributes on files created by tmpfiles. This can be especially used to set SMACK security labels on volatile files and directories. It is done by adding new line of type "t". Such line should contain attributes in Argument field, using following format: name=value All other fields are ignored. If value contains spaces, then it must be surrounded by quotation marks. User can also put quotation mark in value by escaping it with backslash. Example: D /var/run/cups - - - - t /var/run/cups - - - - security.SMACK64=printing

2014-12-04udev: net_setup - allow matching on OriginalName=Tom Gundersen
This has been requested repeatedly, so let's give it a go. We explicitly do not allow matching on names that have already been changed (from a previous udev run, or otherwise), and matching on unpredictable names (ethX) is discouraged (but not currently disallowed). We also currently allow: [Match] Name=veth0 [Link] Name=my-name0 SomeOtherSetting=true Which means that the link file will be applied the first time it is invoked, but not on subsequent invocations, which may be surprising.

2014-12-04udevd: SAS: use SAS addr + PHY id in by-path whenever possible.Maurizio Lombardi
This patch changes the naming scheme for sas disks. The original names used disk's sas address and lun, the new scheme uses sas address of the nearest expander (if available) and a phy id of the used connection. If no expander is used, the phy id of hba phy is used. Note that names that refer to RAID or other abstract devices are unchanged. Name in raid configuration: hba_pci_address-sas-raid_sas_address-lunY-partZ Name in expander bare disk configuration: hba_pci_address-sas-expander_sas_address-phyX-lunY-partZ Name format without expanders: hba_pci_address-sas-phyX-lunY-partZ Signed-off-by: Maurizio Lombardi <mlombard@redhat.com>
