The Design of Unix Shell, by Stephen R. Bourne 
2026-05-13 @ 18:45 local (22:45 UTC) - Backroom of Brass Monkey 55 Little West 12th St

We’re looking at having a “fireside chat” with Stephen R. Bourne, covering everything from shell to its design decisions, and the relevance today.

Some relevant reading for the meeting might be Stephen’s 1978 piece in The Bell System Technical Journal entitled “UNIX Time-Sharing System: The UNIX Shell” https://archive.org/details/bstj57-6-1971(Bell System Technical Journal, Vol 57, No 6, 1978).

Steve Bourne is internationally known for his work on the UNIX operating system. During his career he spent 20 years in senior engineering management positions at computer systems and networking companies. These included Cisco Systems, Sun Microsystems, Digital Equipment and Silicon Graphics. Since 2000 he has been Chief Technology Officer at El Dorado Ventures (now Rally Ventures) in Menlo Park, California.

He is past chair of the ACM Queue board, a magazine that he started in 2003 for software practitioners.

Steve spent nine years at Bell Laboratories as a member of the Seventh Edition UNIX team. He designed the UNIX Command Language sh or “Bourne Shell” which is used for scripting in the UNIX programming environment and he wrote the adb debugger tool. His book “The UNIX System” was widely read and published in 1983.

rpki-client 9.8 released

rpki-client 9.8 has just been released and will be available in the rpki-client directory of any OpenBSD mirror soon. It is recommended that all users upgrade to this version for improved reliability. rpki-client is a FREE, easy-to-use implementation of the Resource Public Key Infrastructure (RPKI) for Relying Parties to facilitate validation of BGP announcements. The program queries the global RPKI repository system and validates untrusted network inputs. The program outputs validated ROA payloads, BGPsec Router keys, and ASPA payloads in configuration formats suitable for OpenBGPD and BIRD, and supports emitting CSV and JSON for consumption by other routing stacks. See RFC 6480 and RFC 6811 for a description of how RPKI and BGP Prefix Origin Validation help secure the global Internet routing system. rpki-client was primarily developed by Kristaps Dzonsons, Claudio Jeker, Job Snijders, Theo Buehler, Theo de Raadt, and Sebastian Benoit as part of the OpenBSD Project. This release includes the following changes to the previous release: - Various refactoring for improved compatibility with various libcrypto implementations and in CA/BGPsec certificate handling. - Fixed an accounting issue in HTTP gzip compression detection. - Added a warning in extra verbose mode (-vv) about standards non-compliant Issuer and Subject ASN.1 string encodings. - Added a check for canonical encoding of ASPA eContent in alignment with draft-ietf-sidrops-aspa-profile-22. - Ensure that a repository timeout correctly stops repository processing. Thanks to Fedor Vompe from Deutsche Telekom for reporting. - Fixed a defect in Canonical Cache Representation ROAIPAddressFamily sort order. As a result, rpki-client 9.8 cannot parse rpki-client 9.7's .ccr files and vice versa. Thanks to Bart Bakker from RIPE NCC for reporting. - Fixed an issue in the parser for the locally configured constraints. Thanks to Daniel Anderson. - A malicious RRDP Publication Server can cause a NULL dereference. Thanks to Daniel Anderson for reporting. - A malicious RPKI Publication Server can cause an incorrect error exit. Thanks to Yuheng Zhang, Qi Wang, Jianjun Chen from Tsinghua University, and Teatime Lab for reporting. rpki-client works on all operating systems with a libcrypto library based on OpenSSL 1.1 or later, LibreSSL 3.6, a libtls library compatible with LibreSSL 3.6 or later, expat and zlib. rpki-client is known to compile and run on at least the following operating systems: Alpine, CentOS, Debian, Fedora, FreeBSD, Red Hat, Rocky, Ubuntu, macOS, and of course OpenBSD! It is our hope that packagers take interest and help adapt rpki-client-portable to more distributions. The mirrors where rpki-client is available can be found on https://www.rpki-client.org/portable.html Reporting Bugs: =============== General bugs may be reported to tech@openbsd.org Portable bugs may be filed at https://github.com/rpki-client/rpki-client-portable We welcome feedback and improvements from the broader community. Thanks to all of the contributors who helped make this release possible. Assistance to coordinate security issues is available via security@rpki-client.org.

F45 Change Proposal: Build_x86-64-v3_Packages [SystemWide]

Wiki: https://fedoraproject.org/wiki/Changes/Build_x86-64-v3_Packages

Discussion Thread: https://discussion.fedoraproject.org/t/187943

**This is a proposed Change for Fedora Linux.**
This document represents a proposed Change. As part of the Changes process, proposals are publicly announced in order to receive community feedback. This proposal will only be implemented if approved by the Fedora Engineering Steering Committee.

== Summary ==

Build x86_64_v3 packages in addition to the current x86_64_v1 builds.

== Owner ==

* Name: [[User:lleyton| Lleyton Gray]], [[User:KyleGospo| Kyle Gospodnetich]], [[User:owensz| Owen Zimmerman]]
* Email: lleyton@fyralabs.com, me@kylegospodneti.ch, owen@fyralabs.com

== Detailed Description ==

This change would introduce a new primary architecture, x86_64_v3. Existing packages built for x86_64 would start being built for v3. The support for installing x86_64 microarch packages are already in libsolv and RPM, but will require changes in DNF and Koji.

== Feedback ==

No feedback at this moment.

== Benefit to Fedora ==

This change allows installing packages compiled against a more recent x86_64 baseline, which can improve system performance for modern machines.

== Scope ==

* Proposal owners:
** Extend Koji to support x86_64 architecture levels
** Add compiler flag definitions for x86_64_v2/v3/v4 to `redhat-rpm-config`
** Add support to DNF5 to transparently use packages for higher levels as appropriate
** Add support to Pungi for x86_64 architecture levels to x86_64 composes
* Other developers:
** Release Engineering: Enable and deliver x86_64_v3 repositories and images for x86_64
* Release engineering: [https://forge.fedoraproject.org/releng/tickets/issues/13310 #13310]
* Policies and guidelines: Packaging guidelines need to be updated to note `%{x86_64}` should be used for architecture conditionals for x86_64 instead of just the plain `x86_64`.
* Trademark approval: N/A (not needed for this Change)
* Alignment with the Fedora Strategy: Building microarchitecture packages for modern systems helps Fedora lead in distribution development. However, this change does not align with any specific objective.

== Upgrade/compatibility impact ==

On upgrade, systems that have support for the x86_64_v3 baseline will automatically install x86_64_v3 packages when available.

== Early Testing (Optional) ==

Do you require 'QA Blueprint' support? N

== How To Test ==

To test, a x86_64 system supporting the v3 baseline is required. When available, DNF will select packages with the highest compatible baseline. Testing involves upgrading or installing 45 on a supported system, ensuring that packages installed are compiled for the x86_64_v3 baseline, and validating that packages built for v3 work as expected.

== User Experience ==

Packages compiled against a higher baseline may perform better on systems which support it.

== Dependencies ==

koji, redhat-rpm-config, pungi, dnf5.

== Contingency Plan ==

* Contingency mechanism: Revert and unpublish x86_64_v3 packages and defer to the next release.
* Contingency deadline: Beta Freeze
* Blocks release? No

== Documentation ==

There's no current upstream documentation for microarch handling in DNF, but for reference, these PRs may be useful:
* https://github.com/rpm-software-management/rpm/pull/2315
* https://github.com/rpm-software-management/dnf5/pull/2591
* https://github.com/rpm-software-management/mock/pull/1733

== Release Notes ==

\n\n\nFedora now provides packages for the x86_64 v3 baseline. When upgrading the system to Fedora 45, DNF will pull packages for x86_64 v3 if the host system is detected as supporting a x86_64 v3 or higher baseline. This may improve system performance on modern machines.

system to the following package versions: Ubuntu 22.04 LTS linux-image-5.15.0-1109-azure 5.15.0-1109.118 linux-image-azure-5.15 5.15.0.1109.107 linux-image-azure-lts-22.04 5.15.0.1109.107 After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.

[USN-8148-6] Linux kernel (Azure) vulnerabilities

========================================================================== Ubuntu Security Notice USN-8148-6 April 14, 2026 linux-azure, linux-azure-6.8 vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 24.04 LTS - Ubuntu 22.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-azure: Linux kernel for Microsoft Azure Cloud systems - linux-azure-6.8: Linux kernel for Microsoft Azure cloud systems Details: Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - Cryptographic API; - Netfilter; - Network traffic control; (CVE-2026-23060, CVE-2026-23074, CVE-2026-23111) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 24.04 LTS linux-image-6.8.0-1052-azure 6.8.0-1052.58 linux-image-azure-6.8 6.8.0-1052.58 linux-image-azure-lts-24.04 6.8.0-1052.58 Ubuntu 22.04 LTS linux-image-6.8.0-1052-azure 6.8.0-1052.58~22.04.1 linux-image-azure 6.8.0-1052.58~22.04.1 linux-image-azure-6.8 6.8.0-1052.58~22.04.1 After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
