Net::SMTP Perl module now supports SSL
This update adds support for implicit and explicit TLS and SSL encryption to the
Perl module. As a result, it is now possible to communicate with SMTP servers through a secured channel. (BZ#1557574
Net::LDAP Perl module no longer defaults to TLS 1.0
Previously, when the
Perl module module was used for upgrading an unsecured LDAP connection to a TLS-protected one, the module used the TLS protocol version 1.0, which is currently considered insecure. With this update, the default TLS version has been removed from
, and both implicit (LDAPS schema) and explicit (LDAP schema) TLS protocols rely on the default TLS version selected in the
Perl module. As a result, it is no longer necessary to override the TLS version in the
clients by passing the
argument to the
method to preserve security. (BZ#1520364
timemaster now supports bonding devices
timemaster program can be used to synchronize the system clock to all available time sources in case that there are multiple PTP domains available on the network, or fallback to NTP is needed.
This update adds the possibility to specify bonding devices in the active-backup mode in the timemaster configuration file.
now checks if the active interface supports software or hardware timestamping and starts
on the bonding interface. (BZ#1549015
pcp rebased to version 4.1.0
The pcp packages have been upgraded to upstream version of Performace Co-Pilot 4.1.0, which provides a number of bug fixes and enhancements over the previous version:
Added a sized-based interim compression to the
pmlogger_check(1) script to reduce data volume sizes on systems configured via the
Daily compressed archive metadata files.
Changed metric labels to first class PCP metric metadata.
Metric help text and labels are now stored in PCP archives.
Added more Linux kernel metrics: virtual machines, TTYs, aggregate interrupt and softirq counters, af_unix/udp/tcp connection (inet/ipv6), VFS locking, login sessions, AIO, capacity per block device, and other.
Performance Metrics Application Programming Interface (PMAPI) and the Performance Metrics Domain Agent (PMDA) API have been refactored, including promotion and deprecation of individual functions.
Added new virtual data optimizer (VDO) metrics to
Improved integration with Zabbix agentd service with further low-level-discovery support in the
Added a new PMDA
pmdabcc(1) for exporting BCC and eBPF trace instrumentation.
Added a new PMDA
to consume metrics from Prometheus end-points. (BZ#1565370
ps utility now displays the Login ID associated with processes
The new format option
luid of the
ps utility now enables you to display the Login ID associated with processes.
To display the login ID attributes of running processes, use the following command:
$ ps -o luid
gcc-libraries rebased to version 8.2.1
The gcc-libraries packages have been updated to upstream version 8.2.1. This update adds the following changes:
libgfortran.so.4 Fortran libraries have been added to enable running applications built with Red Hat Developer Toolset versions 7 and later.
libquadmath library has been added as a dependency of the
The Cilk+ library has been removed. (BZ#1600265)
systemtap rebased to version 3.3
The systemtap packages have been upgraded to upstream version 3.3, which provides a number of bug fixes and enhancements:
Limited support for the extended Berkeley Packet Filter (eBPF) tracing on the Intel64 and AMD64 architectures has been added. Use the
option to use eBPF as a backend. Due to numerous limitations of
and its SystemTap interface, only simple scripts work. For more information, see the Knowledge article https://access.redhat.com/articles/3550581
and the stapbpf(8) manual page.
--sysroot option has been optimized for cross-compiled environments.
--example option allows you to search the example scripts distributed with SystemTap without providing the whole path of the file.
The SystemTap runtime and tapsets are compatible with kernel versions up to 4.17.
Usage of SystemTap on systems with real time kernel or machines with a high number of CPUs has been improved.
Handling of code used for Spectre and Meltdown attack mitigation has been improved. (BZ#1565773
GDB can disassemble instructions for the z14 processor of IBM Z architecture
GDB debugger has been extended to disassemble instructions of the z14 processor of the IBM Z architecture, including guarded storage instructions. Previously,
GDB displayed only the numerical values of such instructions in the
.long 0xNNNN form. With this update,
GDB can correctly display mnemonic names of assembly instructions in code targeting this processor. (BZ#1553104)
New packages: java-11-openjdk
The java-11-openjdk packages provide
OpenJDK 11 support through the
OpenJDK 11 is the next Long-Term Support (LTS) version of Java supported by Red Hat after
OpenJDK 8. It provides multiple new features including Modularization, Application Class Data Sharing, Heap Allocation on Alternative Memory Devices, Local-Variable Syntax for Lambda Parameters, and TLS 1.3 support.
The java-11-openjdk packages do not include unversioned
OpenJDK 11 is not fully compatible with
OpenJDK 8. (BZ#1570856)
Support for new locales in
This update adds support for two new locales: Urdu (ur_IN) and Wolaytta (wal_ET). Additional support has also been added for newer currency symbols like the Euro, such as in
. Users can now specify these locales using the relevant environment variables to take advantage of the new localization support. (BZ#1448107
New OFD Locking constants for 64-bit-offset programs
Open File Descriptor (OFD) locks are superior to per-process locks for some applications. With this update, 64-bit-offset programs (those that have
#define _FILE_OFFSET_BITS 64
) are able to use the
constants in system calls, although they still need to detect if the kernel supports those operations. Note that programs which use 32-bit file offsets do not have access to these constants, as the RHEL 7 ABI does not support translating them. (BZ#1461231
elfutils rebased to version 0.172
The elfutils packages have been upgraded to upstream version 0.172. This update adds support for the DWARF5 debug information format, split-dwarf, and GNU DebugFission:
eu-readelf tool can display split unit DIEs when the
--debug-dump=info+ option is used.
eu-readelf tool can inspect separate
skeleton files with debug information when the
--dwarf-skeleton option is used.
libdw library now tries to resolve the
alt file containing linked debug information even when it has not yet been set with the
library has been extended with the functions
