Samsung docs detail Linux TRIM bug and fix

Filed under
Linux
Security

We've been covering a report from search provider Algolia pointing out a potential issue in Samsung SSDs' TRIM implementation. More recently, Samsung itself reported that the bug actually resides in the Linux kernel, and that the company had submitted a patch for the problem.

Now, we have more details of the bug. Samsung has provided us with internal documents detailing the exact cause of the issue, and the subsequent solution. We're geting a bit technical here, so we'll take some liberty to simplify. When Linux's RAID implementation receives a sequence of read or write operations, it creates separate buffers in memory for each of them.

  • Why Docker is Not Yet Succeeding Widely in Production

    Docker’s momentum has been increasing by the week, and from that it’s clearly touching on real problems. However, for many production users today, the pros do not outweigh the cons. Docker has done fantastically well at making containers appeal to developers for development, testing and CI environments—however, it has yet to disrupt production. In light of DockerCon 2015’s “Docker in Production” theme I’d like to discuss publicly the challenges Docker has yet to overcome to see wide adoption for the production use case. None of the issues mentioned here are new; they all exist on GitHub in some form. Most I’ve already discussed in conference talks or with the Docker team. This post is explicitly not to point out what is no longer an issue: For instance the new registry overcomes many shortcomings of the old. Many areas that remain problematic are not mentioned here, but I believe that what follows are the most important issues to address in the short term to enable more organizations to take the leap to running containers in production. The list is heavily biased from my experience of running Docker at Shopify, where we’ve been running the core platform on containers for more than a year at scale. With a technology moving as fast as Docker, it’s impossible to keep everything current. Please reach out if you spot inaccuracies.

  • A New SysAdmin Pledge in Honor of SysAdmin Day

    In fact, history is filled with examples of great people declaring a holiday for themselves. Take Christopher Columbus, for example. Upon discovering “The New World”, Columbus immediately declared the second Monday in October to be “Columbus Day” (to be celebrated with cake… and balloons… and confetti). It took a year or two to catch on, but before the decade was through, most of the world was already celebrating this new holiday. It's true. Look it up.
