systemd-219-42.el7.10

The systemd packages contain systemd, a system and service manager for Linux, compatible with the SysV and LSB init scripts. It provides aggressive parallelism capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, and keeps track of processes using Linux cgroups. In addition, it supports snapshotting and restoring of the system state, maintains mount and automount points, and implements an elaborate transactional dependency-based service control logic. It can also work as a drop-in replacement for sysvinit.

This update fixes the following bugs:

* If the call of the fork() function failed during the startup of a service, systemd terminated unexpectedly. Consequently, users had to reboot the machine. With this update, systemd has been fixed to print an error message instead of terminating and stopping handling the requests. As a result, systemd keeps working in the described situation. (BZ#1546658)

* If journald rotated the log files quickly enough, and the application which was using the sd_journal API did not read messages fast enough, the API sometimes started losing messages about deleted files. Consequently, the sd_journal API did not close file descriptors for such files, and they were never removed from the disk. To fix this problem, the sd_journal API now reiterates through files, finds those that were removed, and closes their file descriptors, if it detects the loss of messages about deleted files. As a result, the kernel is now able to delete the files completely from the disk. (BZ#1547373)

* Previously, the journalctl utility stopped when it encountered an empty file in the systemd journal logs. With this update, systemd has been fixed to report an error message about such situation, and to continue scanning other files in the journal log under the described circumstances. (BZ#1549474)

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