Container-friendly Alpine Linux may get Java port

Filed under
GNU
Linux

Alpine Linux, a security-focused lightweight distribution of the platform, may get its own Java port. Alpine is popular with the Docker container developers, so a Java port could pave the way to making Java containers very small.

A proposal floated this week on an OpenJDK mailing list calls for porting the JDK (Java Development Kit), including the Java Runtime Environment, Java compiler and APIs, to both the distribution and the musl C standard library, which is supported by Alpine Linux. The key focus here is musl; Java has previously been ported to the standard glibc library, which you can install in Alpine, but the standard Alpine release switched two years ago to musl because it’s much faster and more compact

  • MirageOS Unikernel Effort Moves Forward

    Linux Foundation backed Xen Project helps to advance the state of the MirageOS unikernel operating system with a new release that now supports the KVM hypervisor.
    The open-source MirageOS unikernel project reached a major milestone on Feb. 23, with the launch of MirageOS 3.0. The basic idea behind a unikernel is that it is a highly-optimized and purpose-built operating system that can help to enable efficient operation and delivery of applications.

    The MirageOS 1.0 release debuted back in December 2013 as an effort led by the Linux Foundation's Xen hypervisor virtualization project. With the new MirageOS 3.0 release, the unikernel is now expanding beyond the confines of the Xen hypervisor and now also supports the KVM and Bhyve hypervisors as well.

  • Linux Foundation Forms New Open Network Automation Project

    Today the Linux Foundation consolidated the ECOMP and OPEN-O project to form the new Open Network Automation Project (ONAP). ECOMP perhaps has had the shortest life-span of any Linux Foundation project, lasting barely a month. ECOMP only becamean official Linux Foundation project a few short weeks ago, after being donated by AT&T. The Enhanced Control, Orchestration, Management and Policy (ECOMP) is an effort that AT&T has been building for several years to help enable its network transformation for virtualization.

    OPEN-O on the other hand was announced a year ago, as the Open Orchestrator effort.

Linux

After I resolved to adopt Linux, my confidence grew slowly but surely. Security-oriented considerations were compelling enough to convince me to switch, but I soon discovered many more advantages to the Linux desktop.

For those still unsure about making the transition, or those who have done so but may not know everything their system can do, I'll showcase here some of the Linux desktop's advantages.

  • Profit From the Rising Importance of Linux Software

    You may have noticed that there’s no stock symbol next to Linux’s name. This important OS isn’t made by a public company… or even a company at all.

    Linux software is open source. In other words, it’s not a commercial product which anyone owns. Rather, it’s free software which is developed and improved pro bono by the programmers who use it.

    As a result of this democratized development process, Linux is more customizable than a commercial OS. Windows and MacOS both have proprietary designs with usage restrictions, but not so with Linux.

    This makes Linux software ideal for the advanced programmers and IT professionals who make cloud computing possible. They often like to tinker with hardware and software in order to optimize it for their purposes.

  • Kopano, openSUSE: Yes, we’re open!

    Kopano announced big news yesterday about being included in openSUSE’s factory codebase as development proceeds to be in openSUSE’s upcoming release, which was a big first step toward inclusion into openSUSE downstream.

    “We are straight on the path to be included with openSUSE Leap 42.3 already, which has started development just last December,” wrote Michael Kromer in a news release yesterday. “You can find the downstream requests from Factory to Leap 42.3 here: Core and WebApp.”

    Being one of the most popular Linux distros, Kopano expressed delight to be the first distribution to pick the communication solution.

You will also notice some improvements around ffmpeg, and MPV which is from now the main media player in Zenwalk. Gstreamer has been dropped from ISO but is still available from Slackware repositories. Of course this ISO contains many updated packages (see changelog below).

  • Stop using SHA1 encryption: It’s now completely unsafe, Google proves
    Security researchers have achieved the first real-world collision attack against the SHA-1 hash function, producing two different PDF files with the same SHA-1 signature. This shows that the algorithm's use for security-sensitive functions should be discontinued as soon as possible. SHA-1 (Secure Hash Algorithm 1) dates back to 1995 and has been known to be vulnerable to theoretical attacks since 2005. The U.S. National Institute of Standards and Technology has banned the use of SHA-1 by U.S. federal agencies since 2010, and digital certificate authorities have not been allowed to issue SHA-1-signed certificates since Jan. 1, 2016, although some exemptions have been made. However, despite these efforts to phase out the use of SHA-1 in some areas, the algorithm is still fairly widely used to validate credit card transactions, electronic documents, email PGP/GPG signatures, open-source software repositories, backups and software updates.
  • on pgp
    First and foremost I have to pay respect to PGP, it was an important weapon in the first cryptowar. It has helped many whistleblowers and dissidents. It is software with quite interesting history, if all the cryptograms could tell... PGP is also deeply misunderstood, it is a highly successful political tool. It was essential in getting crypto out to the people. In my view PGP is not dead, it's just old and misunderstood and needs to be retired in honor. However the world has changed from the internet happy times of the '90s, from a passive adversary to many active ones - with cheap commercially available malware as turn-key-solutions, intrusive apps, malware, NSLs, gag orders, etc.
  • Cloudflare’s Cloudbleed is the worst privacy leak in recent Internet history
    Cloudflare revealed today that, for months, all of its protected websites were potentially leaking private information across the Internet. Specifically, Cloudflare’s reverse proxies were dumping uninitialized memory; that is to say, bleeding private data. The issue, termed Cloudbleed by some (but not its discoverer Tavis Ormandy of Google Project Zero), is the greatest privacy leak of 2017 and the year has just started. For months, since 2016-09-22 by their own admission, CloudFlare has been leaking private information through Cloudbleed. Basically, random data from random sites (again, it’s worth mentioning that every site that used CloudFlare in the last half year should be considered to having fallen victim to this) would be randomly distributed across the open Internet, and then indefinitely cached along the way.
  • Serious Cloudflare bug exposed a potpourri of secret customer data
    Cloudflare, a service that helps optimize the security and performance of more than 5.5 million websites, warned customers today that a recently fixed software bug exposed a range of sensitive information that could have included passwords and cookies and tokens used to authenticate users. A combination of factors made the bug particularly severe. First, the leakage may have been active since September 22, nearly five months before it was discovered, although the greatest period of impact was from February 13 and February 18. Second, some of the highly sensitive data that was leaked was cached by Google and other search engines. The result was that for the entire time the bug was active, hackers had the ability to access the data in real-time by making Web requests to affected websites and to access some of the leaked data later by crafting queries on search engines. "The bug was serious because the leaked memory could contain private information and because it had been cached by search engines," Cloudflare CTO John Graham-Cumming wrote in a blog post published Thursday. "We are disclosing this problem now as we are satisfied that search engine caches have now been cleared of sensitive information. We have also not discovered any evidence of malicious exploits of the bug or other reports of its existence."

    Looks like it is time to change all the passwords again. There’s a tiny little flaw in a CDN used … everywhere, it seems.
  • Today's leading causes of DDoS attacks [Ed: The so-called 'Internet of things' (crappy devices with identical passwords) is a mess; programmers to blame, not Linux]
    Of the most recent mega 100Gbps attacks in the last quarter, most of them were directly attributed to the Mirai botnet. The Mirai botnet works by exploiting the weak security on many Internet of Things (IoT) devices. The program finds its victims by constantly scanning the internet for IoT devices, which use factory default or hard-coded usernames and passwords.

  • SHA-1 is dead, long live SHA-1!
    Unless you’ve been living under a rock, you heard that some researchers managed to create a SHA-1 collision. The short story as to why this matters is the whole purpose of a hashing algorithm is to make it impossible to generate collisions on purpose. Unfortunately though impossible things are usually also impossible so in reality we just make sure it’s really really hard to generate a collision. Thanks to Moore’s Law, hard things don’t stay hard forever. This is why MD5 had to go live on a farm out in the country, and we’re not allowed to see it anymore … because it’s having too much fun. SHA-1 will get to join it soon.

  • Red Hat: 'use after free' vulnerability found in Linux kernel's DCCP protocol IPV6 implementation
    Red Hat Product Security has published details of an "important" security vulnerability in the Linux kernel. The IPv6 implementation of the DCCP protocol means that it is possible for a local, unprivileged user to alter kernel memory and escalate their privileges. Known as the "use-after-free" flaw, CVE-2017-6074 affects a number of Red Hat products including Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 7 and Red Hat Openshift Online v2. Mitigating factors include the requirement for a potential attacker to have access to a local account on a machine, and for IPV6 to be enabled, but it is still something that will be of concern to Linux users. Describing the vulnerability, Red Hat says: "This flaw allows an attacker with an account on the local system to potentially elevate privileges. This class of flaw is commonly referred to as UAF (Use After Free.) Flaws of this nature are generally exploited by exercising a code path that accesses memory via a pointer that no longer references an in use allocation due to an earlier free() operation. In this specific issue, the flaw exists in the DCCP networking code and can be reached by a malicious actor with sufficient access to initiate a DCCP network connection on any local interface. Successful exploitation may result in crashing of the host kernel, potential execution of code in the context of the host kernel or other escalation of privilege by modifying kernel memory structures."
