My friends in the content design team for Linux on IBM Z and LinuxOne have been very productive—here are their latest papers, hot off the press:• White paper - Crypto Express Support for IBM SEL
Learn how the Crypto Express support of IBM Secure Execution for Linux allows a Secure Execution guest to securely use a Crypto Express adapter in both accelerator mode and as EP11 Hardware Security Module.
https://www.ibm.com/docs/en/linux-on-systems?topic=sel-white-paper-crypto-express-support-secure-execution-linux• Using the Dump Tools - Kernel 7.1, with two new examples.
https://www.ibm.com/docs/en/linux-on-systems?topic=tools-kernel-71• libica version 4.4.2
libica version 4.4.2 provides FIPS 140-3 certification updates, for example, higher RSA key lengths.

libzpc - A Protected-Key Cryptographic Library
https://www.ibm.com/docs/en/linux-on-systems?topic=library-libzpc-15There is one enhancement in the libzpc 1.5 version:
libzpc 1.5 now reacts to a verification pattern mismatch caused by live guest relocation or migration by re-creating the protected keys from the key material it was derived from. -

I just published the January report for open source software packages for Linux on #IBMZ and #LinuxONE 🐧
The team tested nearly two dozen projects, including doxygen, elastic Logstash, and PHP.
Elsewhere in the open source world, Apache Tika and WeKan began releasing s390x containers, and libdfp was on-boarded to our GitHub Actions service 🎉

The #s390x open source software team at IBM confirms the latest versions of various software packages run well on #Linux on #IBMZ & #LinuxONE
In December 2024 validation was maintained for over 30 projects, including @ApacheKafka
#HAProxy #SonarQubeWe also saw community CI added for the Zxilly go-site-analyzer, and the Zig programming language, along with CI & binaries for ruri and scie-jump

#ChatOps has come a long way since we had notifications in IRC 😅
In "Leveraging an Intelligent Chatbot for IBM Z Operations at Dutch Tax Office" at #IBMZDay they're demonstrating (on desktop and mobile!) how use of #IBMZ ChatOps has helped new employees get up to speed more quickly as they integrate tons of features into their ChatOps environment (application status, restarts, etc), which simplifies basic (and some more complicated!) interaction with the #mainframe
