The CentOS blog has announced the release of CentOS Stream 9:

CentOS Stream is a continuous-delivery distribution providing each point-release of Red Hat Enterprise Linux (RHEL). Before a package is formally introduced to CentOS Stream, it undergoes a battery of tests and checks—both automated and manual—to ensure it meets the stringent standards for inclusion in RHEL. Updates posted to Stream are identical to those posted to the unreleased minor version of RHEL. The aim? For CentOS Stream to be as fundamentally stable as RHEL itself.

To achieve this stability, each major release of Stream starts from a stable release of Fedora Linux—In CentOS Stream 9, this begins with Fedora 34, which is the same code base from which RHEL 9 is built. As updated packages pass testing and meet standards for stability, they are pushed into CentOS Stream as well as the nightly build of RHEL.

It is natural, when looking at the kernel development process, to focus on patches that find their way to acceptance and become a part of future kernels. But there can be value in looking at work that doesn't clear the bar; in failing, these patches often reveal things about the kernel and the community that creates it. Such is the case with the proof-of-concept namespacefs patch series recently posted by Yordan Karadzhov. One should not expect to see namespacefs in a future kernel but, in failing, this work showed a real use case and why it is hard to satisfy that use case in the kernel.

Security updates have been issued by CentOS (krb5 and mailman), Debian (gmp and librecad), Fedora (php-symfony4 and wireshark), Mageia (bluez, busybox, docker-containerd, gfbgraph, hivex, nss, perl/perl-Encode, and udisks2/libblockdev), openSUSE (permissions), Oracle (mailman and mailman:2.1), Red Hat (mailman, mailman:2.1, and nss), Scientific Linux (mailman and nss), and SUSE (nodejs14).

Writing (correct) concurrent code that uses locking to avoid race conditions is difficult enough. When the objective is to use lockless algorithms, relying on memory barriers instead of locks to eliminate locking overhead, the problem becomes harder still. Bugs are easy to create and hard to find in this type of code. There may be some help on the way, though, in the form of this patch set from Marco Elver that enhances the Kernel Concurrency Sanitizer (KCSAN) with the ability to detect some types of missing memory barriers.

Version 1.57.0 of the Rust language is out. "Rust 1.57 brings panic! to const contexts, adds support for custom profiles to Cargo, and stabilizes fallible reservation APIs."

Over on the Project Zero blog, Tavis Ormandy has a lengthy postmortem on a vulnerability that he found in the Network Security Services (NSS) cryptography library. The vulnerability is a bog-standard buffer overflow that has existed in the library since 2012 despite various kinds of static analysis, testing, and fuzzing that Mozilla and others have applied to it over the years. He found it with a new fuzzing technique:

To solve this problem, I’ve been experimenting with monitoring the call stack during execution.

The naive implementation is too slow to be practical, but after a lot of optimization I had come up with a library that was fast enough to be integrated into coverage-guided fuzzing, and was testing how it performed with NSS and other libraries.

[...] The fuzzer I was using is able to isolate and extract interesting new ASN.1 OIDs, SEQUENCEs, INTEGERs, and so on. Once extracted, it can then randomly combine or insert them into template data. This isn’t really a new idea, but is a new implementation. I'm planning to open source this code in the future.

Security updates have been issued by CentOS (kernel, openssh, and rpm), Debian (nss), Fedora (seamonkey), Mageia (glibc), openSUSE (go1.16, go1.17, kernel, mariadb, netcdf, openexr, poppler, python-Pygments, python-sqlparse, ruby2.5, speex, and webkit2gtk3), Oracle (nss), Red Hat (nss), SUSE (clamav, glibc, gmp, go1.16, go1.17, kernel, mariadb, netcdf, OpenEXR, openexr, openssh, poppler, python-Pygments, python-sqlparse, ruby2.1, ruby2.5, speex, webkit2gtk3, and xen), and Ubuntu (nss and thunderbird).

A seemingly straightforward question aimed at candidates for the in-progress Fedora elections led to a discussion on the Fedora devel mailing list that branched into a few different directions. The question was related to a struggle that the distribution has had before: whether using non-free Git forges is appropriate. One of the differences this time, though, is that the focus is on where source-git (or src-git) repositories will be hosted, which is a separate question from where the dist-git repository lives.

The Software Freedom Conservancy provides an update on its suit against Vizio for copyleft license violations. Vizio's response was not to release the source code:

Instead, Vizio filed a request to "remove" the case from California State Court (into US federal court), which indicates Vizio's belief that consumers have no third-party beneficiary rights under copyleft! In other words, Vizio’s answer to this complaint is not to comply with the copyleft licenses, but instead imply that Software Freedom Conservancy — and all other purchasers of the devices who might want to assert their right under GPL and LGPL to complete, corresponding source — have no right to even ask for that source code.

Stable kernels 5.15.6, 5.10.83, 5.4.163, and 4.19.219 have been released. They all contain important fixes throughout the tree. Users of those series should upgrade.

Security updates have been issued by Debian (rsync, rsyslog, and uriparser), Fedora (containerd, freeipa, golang-github-containerd-ttrpc, libdxfrw, libldb, librecad, mingw-speex, moby-engine, samba, and xen), Red Hat (kernel, kernel-rt, kpatch-patch, and samba), and Ubuntu (linux, linux-aws, linux-aws-5.11, linux-azure, linux-azure-5.11, linux-gcp, linux-gcp-5.11, linux-hwe-5.11, linux-kvm, linux-oracle, linux-oracle-5.11, linux-raspi, linux, linux-aws, linux-aws-5.4, linux-azure, linux-gcp, linux-gke, linux-gke-5.4, linux-gkeop, linux-gkeop-5.4, linux-hwe-5.4, linux-kvm, linux-oracle, linux-oracle-5.4, linux, linux-aws, linux-aws-hwe, linux-azure, linux-azure-4.15, linux-dell300x, linux-gcp-4.15, linux-hwe, linux-kvm, linux-oracle, linux-raspi2, linux-snapdragon, linux, linux-aws, linux-azure, linux-gcp, linux-kvm, linux-oem-5.13, linux-oracle, linux-raspi, and linux-oem-5.14).

Version 1.7 of the Julia programming language has been released. The list of new features is long; see the release announcement and this LWN article for the details.

καλησπέρα, είμαι καινούργιο μέλος , φοιτητής στην πάτρα! Έχω πρόβλημα με το registration email mutuelle entreprise, έχω δοκιμάσει με δύο διαφορετικά emails , και σε hotmail και σε gmail αλλά δεν μου ήρθε το email σε κανένα από τα δύο.

Ίσως θα έπρεπε να ζητήσεις ειδικά από τον διαχειριστή να σε βοηθήσει γιατί αυτό έκανα την πρώτη φορά που ήρθα εδώ.

While there are few rules on the names of variables, classes, functions, and so on (i.e. identifiers) in the Python language, there are some guidelines on how those things should be named. But, of course, those guidelines were not always followed in the standard library, especially in the early years of the project. A suggestion to add aliases to the standard library for identifiers that do not follow the guidelines seems highly unlikely to go anywhere, but it led to an interesting discussion on the python-ideas mailing list.

Security updates have been issued by Debian (samba), Fedora (kernel), openSUSE (netcdf and tor), SUSE (netcdf and python-Pygments), and Ubuntu (imagemagick).

One of the key features of the extended BPF virtual machine is the verifier built into the kernel that ensures that all BPF programs are safe to run. BPF developers often see the verifier as a bit of a mixed blessing, though; while it can catch a lot of problems before they happen, it can also be hard to please. Comparisons with a well-meaning but rule-bound and picky bureaucracy would not be entirely misplaced. The bpf_loop() proposal from Joanne Koong is an attempt to make pleasing the BPF bureaucrats a bit easier for one type of loop construct.

Security updates have been issued by Debian (bluez, icu, libntlm, libvorbis, libvpx, opensc, roundcube, and tar), Fedora (kernel, kernel-headers, kernel-tools, puppet, slurm, stargz-snapshotter, and suricata), openSUSE (netcdf), Oracle (bluez, kernel, kernel-container, krb5, mailman:2.1, openssh, python3, and rpm), Red Hat (samba), and SUSE (xen).

The 5.16-rc3 kernel prepatch is out for testing. "So rc3 is usually a bit larger than rc2 just because people had some time to start finding things. So too this time, although it's not like this is a particularly big rc3."

Version 8.1.0 of the PHP language has been released. This release includes a number of new features, including enumerations, read-only properties, fibers, and more.

Meanwhile, a new foundation has been created to support development of PHP:

The initial purpose of the PHP Foundation is to support the development of PHP by contracting developers to work on php-src either part-time or full-time. If that sounds interesting to you, be sure to apply!

The foundation does not have any decision-making power on language changes: these remain within the sole purview of the internals mailing list and the RFC process. The fact that some work has been funded by the foundation does not imply that it will be accepted into PHP.

More information can be found in this blog entry.

Greg Kroah-Hartman has announced the release of six new stable kernels: 5.10.82, 5.4.162, 4.19.218, 4.14.256, 4.9.291, and 4.4.293. These kernels contain lots of important fixes throughout the tree; users of those series should upgrade.

Security updates have been issued by Fedora (freerdp, gnome-boxes, gnome-connections, gnome-remote-desktop, guacamole-server, hydra, java-1.8.0-openjdk-aarch32, medusa, mingw-gstreamer1, mingw-gstreamer1-plugins-bad-free, mingw-gstreamer1-plugins-base, mingw-gstreamer1-plugins-good, php, pidgin-sipe, remmina, vinagre, and weston), openSUSE (kernel and netcdf), and SUSE (kernel and netcdf).

The 5.1.15 stable kernel has been released. As usual, it contains lots of important fixes throughout the kernel tree. Users should upgrade.

Security updates have been issued by Fedora (busybox, getdata, and php), Mageia (couchdb, freerdp, openexr, postgresql, python-reportlab, and rsh), openSUSE (bind, java-1_8_0-openjdk, and kernel), SUSE (java-1_7_0-openjdk), and Ubuntu (icu).

Security updates have been issued by Debian (openjdk-17), Fedora (libxls, roundcubemail, and vim), openSUSE (bind, java-1_8_0-openjdk, and redis), Red Hat (kernel, kernel-rt, kpatch-patch, krb5, mailman:2.1, openssh, and rpm), Scientific Linux (kernel, krb5, openssh, and rpm), SUSE (bind, java-1_8_0-openjdk, redis, and webkit2gtk3), and Ubuntu (bluez).

Security updates have been issued by Debian (mbedtls), Red Hat (kernel and rpm), and Ubuntu (freerdp2).

Amazon has announced a preview release of its upcoming AL2022 distribution. The company plans to support AL2022 for five years after its release.

AL2022 uses the Fedora project as its upstream to provide customers with a wide variety of the latest software, such as updated language runtimes, as part of quarterly releases. In addition, AL2022 has SELinux enabled and enforced by default.

The second 5.16 kernel prepatch is out for testing. "Nothing especially noteworthy stands out for the last week, it all felt pretty normal for a rc2 week".

Security updates have been issued by Debian (firebird3.0, libmodbus, and salt), Fedora (js-jquery-ui and wordpress), Mageia (arpwatch, chromium-browser-stable, php, rust, and wireshark), openSUSE (barrier, firefox, hylafax+, opera, postgresql12, postgresql13, postgresql14, and tomcat), SUSE (ardana-ansible, ardana-monasca, crowbar-openstack, influxdb, kibana, openstack-cinder, openstack-ec2-api, openstack-heat-gbp, openstack-heat-templates, openstack-horizon-plugin-gbp-ui, openstack-keystone, openstack-neutron-gbp, openstack-nova, python-eventlet, rubygem-redcarpet, rubygem-puma, ardana-ansible, ardana-monasca, documentation-suse-openstack-cloud, openstack-ec2-api, openstack-heat-templates, python-Django, python-monasca-common, rubygem-redcarpet, rubygem-puma, firefox, kernel, postgresql, postgresql13, postgresql14, postgresql10, postgresql12, postgresql13, postgresql14, postgresql96, and samba), and Ubuntu (libreoffice).

The 5.15.4, 5.14.21, 5.10.81, and 5.4.161 stable kernels have been released. Each contains another set of important updates, but it's worth noting that 5.4.161 hasn't been through the usual review process due to an amusing bit of scripting confusion.

@trendy. ευχαριστώ για την απάντηση. το εγκατέστησα και μπερδευτηκα τι πρέπει να κάνω.

το έχασα με το Default Download Rate 50 και Default upload Rate 50 που έχει by default. θέλω να είναι ελεύθερο όσο πιάνει η γραμμή, εκτός αν έχω περάσεις κάποιες IPs να έχουν συγκεκριμμένο up/down.
δοκίμασα να περάσα στο laptop κανόνα για 10Μ/512κ αλλά δεν δείχνει να πιάνει ο περιορισμός στο speedtest.net τουλάχιστον.
θέλω να είναι ολα σε kbps, Mbps.
