RHBA-2016:2698-1

2016-11-09

systemd-219-30.el7_3.6.src.rpm

RHBA-2017:0371-1

systemd-219-30.el7_3.7.src.rpm

Details

Previously, there was a bug in the way systemd handled resource limits. As a
consequence, setting resource limits failed, displaying the error "Failed to
parse resource value, ignoring". This bug has been fixed, and systemd no longer
fails when setting resource limits. (BZ#1399638)
Previously, there was a bug in the add_random function in systemd. This caused
systemd to terminate unexpectedly under certain circumstances. This update fixes
the bug, and systemd no longer crashes in these situations. (BZ#1399639)

Details:

Previously, there was a bug in the way systemd handles resource limits
specification. As a consequence, setting resource limits failed, displaying the
error "Failed to parse resource value, ignoring". This bug has been fixed, and
systemd no longer fails when setting resource limits. (BZ#1399638)
Previously, there was a bug in the add_random function in systemd. This caused
systemd to sometimes terminate unexpectedly when a unit was scheduled to run at
a specific time, without any randomized delay. This update fixes the bug, and
systemd no longer crashes in the described situation. (BZ#1399639)

Users of systemd are advised to upgrade to these updated packages, which fix
these bugs.

RHBA-2017:1311-1

2017-05-25

systemd-219-30.el7_3.9.src.rpm

Previously, if there was a require dependency between units (for example,
neutron-openvswitch-agent requiring openvswitch), restarting was propagated to
the dependent unit even if the dependent unit was not running. For example,
restarting openvswitch started also the dependent neutron-openvswitch-agent even
when it was in the stopped state. With this update, restarting propagation has
been changed to try-restart, and stopped dependent units are no longer started.
As a result, neutron-openvswitch-agent remains in the stopped state in the
described example. (BZ#1443992)

2016-08-02

systemd-219-19.el7_2.12.src.rpm

This update fixes the following bug:

Previously, the garbage collector inside systemd had N! (factorial of N)
worst-case complexity, where N is the number of units. Consequently, the system
hung during shutdown if a lot of units were stopped. The algorithm has been
changed to have N^2 (square of N) worst-case complexity, and the system no
longer hangs in the described scenario. (BZ#1346292)

RHBA-2016:1835-2

2016-09-14

systemd-219-19.el7_2.13.src.rpm

This update fixes the following bugs:

Previously, the cgroups-agent program used D-Bus for its messaging. Because
the dbus-daemon used a backlog of 30 connections on its D-bus system bus socket,
reaching the limit of 30 queued connections could consequently result in losing
cgroup empty messages from further connections. This update adds a separate
cgroup agent socket of the AF_UNIX/SOCK_DGRAM type, which needs no connection
set up and for no listen() backlog applies. Now, if the cgroups-agent binary
file cannot queue datagram messages, it does not attempt for re-connection but
instead blocks the datagram messages. As a result, cgroup empty messages are no
longer lost, the session scopes for an SSH connection no longer trigger a memory
leak, and the load increases. (BZ#1360159)
Previously, an inefficient algorithm for reaping processes caused that the
systemd service became unresponsive when a large number of processes terminated
in a short interval. The algorithm has been improved, and systemd is now able to
reap the processes more quickly, which prevents the described hang from
occurring. (BZ#1360160)

RHBA-2016:2965-1

2016-12-20

systemd-219-19.el7_2.20.src.rpm

This update adds the following enhancement:

The /dev/disk/by-id/ directory now contains symlinks to Non-volatile Memory
Express (NVMe) drives that are present on the system. With this update, symlinks
based on device World Wide Name, model number, and serial number are created.
This allows the administrator to use persistent device names in configuration
https://www.freedesktop.org/software/systemd/man/systemd-journal-remote.html#files, for example in /etc/fstab. (BZ#1388900)
