Recent news has reported that an urgent data corruption issued has destroyed file systems in
Linux 4.14 and if you are using bcache to speed up your Linux 4.14 you are being urged to stop it immediately if you want your data to survive.
Linux Compatibility
Linux is an open-source technology and hundreds of programmers have been involved with adding software that is completely open source and accessible to all. Anyone can download the source code and make changes to it and one of the main advantages of this is the wide range of options that users have and the increased security that can be found in it too. There are several distributions available including Debian, Ubuntu, and Mint. Security is exceptional and several hackers have been involved in contributing to the security of Linux.
Linux is becoming more and more popular and with a little knowledge and a computer you can do so much. You can use Siri to control your home, you can set up a home surveillance system, control your air conditioning, and so much more. In fact, you can probably do pretty much anything using Linux if you give it a little thought. Linux is an operating system and is essentially a collection of basic instructions written in code that tell the different electronic parts on your computer what to do and how to work. As the software is open source, it means that anyone can use it to see how it works and if they want they can make changes to it.
Linux was initially intended to be developed into its own operating system but this never happened. The great thing about Linux is that it is also used without GNU in embedded systems, mobile phones, appliances, and more. There is so much that can be done with this open source tool and that is why it is so popular. Users want the freedom to explore, to change, to make things better and by using Linux they get the chance to do this and become a part of a massive community of coders and developers. Bugs are found very quickly and dealt with very quickly too.
The Linux operating system is a great alternative to Windows and is being recognized in so many different circles including online casinos. There was a time when Linux users were excluding from online gaming but the big name brands can now access a lot of the best online gambling and gaming sites where there can play the best games. You can get more info on these games here. Ubuntu is the most widely used of the Linux operating systems and this is mainly due to its ease of use and because it is free. Any Ubuntu browser that supports flash graphics and animations will be able to access online games and the only thing you need to install is Adobe Flash Player.
Filesystem-eating Bug Fix for Linux 4.14
The news that a filesystem-eating but has been found in Linux 4.14 has spread like wildfire. Updates and discussions are available on all the major developer and coding sites around the world. The filesystem-eating but was first reported by Pavel Goran, a developer who informed the community that a problem had struck bcache. He said that he noticed the problem after an upgrade of Gentoo from version 4.13 to 4.14. He explained that what he noticed was that the read from the bcache device were actually producing different data between the two iterations.
He spent some time going over and analyzing the problem before going live with his findings and said, “this looks like a very serious bug that can corrupt or completely destroy the data on bcache devices.”
If you don’t know, bcache allows the use of a SSD drive as a read/write cache and can also be used for as a data storage instrument for another drive or to store information onto faster media disc.
After reading Goran’s report, others checked out the issue and agreed with the problem.
The bug was then added to the Gentoo Bugs list so all users would be made aware of it. The cause of the problem was investigated and was later identified as being:
A new field was introduced in 74d46992e0d9, bi_partno, instead of using bdev->bd_contains and encoding the partition information in the bi_bdev field. __bio_clone_fast was changed to copy the disk information, but not the partition information. At minimum, this regressed bcache and caused data corruption.
A fix for the problem has been found and implemented which will appear in Linux 4.14.1. Kernel
4.14.2 stable is also out and it fixes the bcache corruption bug. The fix is not on antic repo yet. It will also be included in Linux 4.15 which is due to be released in the next month or two. Many users don’t know how to use bcache and if they don’t use it they won’t have any problems with Linux 4.14.
Reddit has a very active thread where users are reporting on their experiences and how the
fixes are working.
