Linux 4.3 Reached End of Life; Users Need To Move To Linux 4.4

prisoninmate writes: As some of you may know, Linux 4.3 was not an LTS (Long Term Support) release, so the last maintenance build is now Linux kernel 4.3.6, as announced earlier by Greg Kroah-Hartman, a renowned kernel developer and maintainer. While he's telling users of the Linux 4.3 series to update to the 4.3.6 point release, he also urges them, especially OS vendors, to move to the most advanced stable series, in this case, Linux kernel 4.4 LTS, which just received its second point release the other day. However, it appears that Linux kernel 4.3.6 is quite an update, as it changes a total of 197 files, with 2310 insertions and 963 deletions, bringing some much-needed improvements.

      Which is insane. Distros should just follow the stable upstream kernels. The Linux ABI is solid so there's absolutely no reason to stick with an old kernel that the distro may have patched. We already know that many distros are bad at fixing security problems in their package repositories, perhaps the kernel package maintainers have a better track record. That said, it's still a completely unnecessary extra step for patches to have to be backported for every single security hole found and fixed upstream.

Worse, you should avoid embarrassing yourself with the claim that it is "plain" silly, because actually it is a mainstream argument that is a standard, traditional corollary to the point you did hear about that mention.

    Yes, over time bugs are better known. That means they've already been mitigated. The new bugs that you don't know about, haven't been mitigated. In old-school *nix, it was normal to have ancient bugs in software specifically because it was very important to the security of the system and the known holes all had mitigation strategies.

    It is still applicable. The reason a lot of youngsters these days are confused by the whole situation is that general purpose workstations that are frequently updated because they have applications that get updated, well those systems aren't locked down in the way a server is; those systems have poor security practices generally, because of the tradeoff between security and convenience. A person who doesn't care about the app updates can use the old system, and will likely be more secure even with the old bugs, if they're mitigating the ones that need mitigation.
