UKSM Is Still Around For Data Deduplication Of The Linux Kernel

Phoronix - 4 hours 42 min ago
Several years back we wrote about Ultra Kernel Samepage Merging (UKSM) for data de-duplication within the Linux kernel for transparently scanning all application memory and de-duping it where possible. While the original developer is no longer active, a new developer has been maintaining the work and continues to support it on the latest Linux kernel releases...

  • Linux Foundation smushes two smaller projects together to form Open Networking Automation Platform

    The Linux Foundation announced yesterday that it had combined open source ECOMP and the Open Orchestrator Project into ONAP, the Open Networking Automation Platform, with the aim of helping users automate network service delivery, design, and service through a unified standard.

    Jim Zemlin, executive director of the Linux Foundation, said that ONAP should be a boon to enterprise IT departments, thanks to improved speed and flexibility.

  • Linux Foundation merges Open Source ECOMP, OPEN-O, further harmonizes virtualization group efforts

    Open source ECOMP and the Open Orchestrator Project (OPEN-O) have merged to create the new Open Network Automation Platform (ONAP) Project, further harmonizing the ever-growing array of disparate virtualization groups.

    ONAP will allow end users to automate, design, orchestrate, and manage services and virtual functions.

  • I am a Cranky, White, Male Feminist

    Today, I was re-reading an linux.com article from 2014 by Leslie Hawthorne which had been reshared by the Linux Foundation Facebook account yesterday in honor of #GirlDay2017 (which I was regrettably unaware of until it was over). It wasn’t so much the specific content of the article that got me thinking, but instead the level of discourse that it “inspired” on the Facebook thread that pointed me there (I will not link to it as it is unpleasant and reflects poorly on The Linux Foundation, an organization which is in most circumstances largely benevolent).

  • encyclopedia snabb and the case of the foreign drivers

    Peoples of the blogosphere, welcome back to the solipsism! Happy 2017 and all that. Today's missive is about Snabb (formerly Snabb Switch), a high-speed networking project we've been working on at work for some years now.

    What's Snabb all about you say? Good question and I have a nice answer for you in video and third-party textual form! This year I managed to make it to linux.conf.au in lovely Tasmania. Tasmania is amazing, with wild wombats and pademelons and devils and wallabies and all kinds of things, and they let me talk about Snabb.

Experimental Patches Revised For AMDGPU HDMI Stereo 3D, DAL/DC Now Supported

Phoronix - 7 hours 48 min ago
Last month an independent contributor to the AMD Linux graphics stack posted AMDGPU patches for HDMI Stereo 3D support within this open-source Radeon DRM driver. Those patches were rather dismissed in part because they didn't implement the support along the new DAL/DC display code-paths, but that has now changed...

Persistent Memory Usage in Linux

LXer - 8 hours 13 min ago
In most cases, when a machine crashes or fails, we lose whatever we had loaded into memory, which for some applications can result in quite a bit of time and effort to recover when the system comes back online. At LinuxCon Europe, Maciej Maciejewski, Senior Software Engineer at Intel, talked about how persistent memory can be used to retain its contents after a power failure.

Nexus 5 with UBports - safe?

Reddit - 9 hours 59 min ago

Hi, to keep things short, I don't want the government or some other dickhead snooping around my phone. I also want to use Whatsapp on the phone. These are literally my only requirements.

I thought about buying a used Nexus 5 and install the UBports Ubuntu Touch on it. Now the main question - android apps do work on that phone, so rootkits will probably too? Is it even worth the hassle to switch considering the Android itself at least is "just" open door and has decent rights management?

  • Watershed SHA1 collision just broke the WebKit repository, others may follow

    The bug resides in Apache SVN, an open source version control system that WebKit and other large software development organizations use to keep track of code submitted by individual members. Often abbreviated as SVN, Subversion uses SHA1 to track and merge duplicate files. Somehow, SVN systems can experience a severe glitch when they encounter the two PDF files published Thursday, proving that real-world collisions on SHA1 are now practical.

  • Cloudflare Reverse Proxies are Dumping Uninitialized Memory

    Thanks to Josh Triplett for sending us this Google Project Zero report about a dump of unitialized memory caused by Cloudflare's reverse proxies. "A while later, we figured out how to reproduce the problem. It looked like that if an html page hosted behind cloudflare had a specific combination of unbalanced tags, the proxy would intersperse pages of uninitialized memory into the output (kinda like heartbleed, but cloudflare specific and worse for reasons I'll explain later). My working theory was that this was related to their "ScrapeShield" feature which parses and obfuscates html - but because reverse proxies are shared between customers, it would affect *all* Cloudflare customers. We fetched a few live samples, and we observed encryption keys, cookies, passwords, chunks of POST data and even HTTPS requests for other major cloudflare-hosted sites from other users. Once we understood what we were seeing and the implications, we immediately stopped and contacted cloudflare security. "

How to Install Apache Directory Studio and Connect to an OpenLDAP Server

LXer - 11 hours 39 min ago
If you happen to administer one or more OpenLDAP servers, you know that they can be a challenge to work with. Working with LDAP itself can be a bit tricky; to that end, many opt to go the phpLDAPadmin route (which is an amazing tool for individual servers). There’s one particular piece of software that does an outstanding job of managing multiple LDAP servers: Apache Directory Studio.
