Linux 4.9 has 'issues that just shouldn't be issues'. Or might not

Linus Torvalds both is and isn't worried about progress towards next release


Linux overlord Linus Torvalds is both worried and chilled about the progress of Linux 4.9. Or maybe he isn't: his weekly message about the latest release candidate has a bet each way.

“We're getting further in the rc series, and while things have stayed pretty calm, I'm not sure if we're quite there yet,” he posted to the Linux Kernel Mailing List on Sunday evening. But in the next sentence, he calms down, saying “This may be one of those releases that have an rc8, which considering the size of 4.9 is perhaps not that unusual.”

In the next paragraph of his post he again expresses both worry and calm.

“That said, nothing particular is bothering me all that much, but we've had some of the VMALLOC_STACK fixups continue to trickle in, so I worry that we're not quite done there yet.”

He does it again in the next paragraph, first saying ““The fact that rc6 is bigger than rc5 was is not a particularly great sign” before then saying the situation is probably “just the usual timing fluctuation: rc6 had networking updates, rc5 didn't, for example.”

“There are also some rdma updates etc that stand out. Nothing that looks particularly worrisome.”

Perhaps the only way to figure out whether Linus is right to worry, or right to chill, is to follow is regular final exhortation: “Go forth and test.” ®

  • Everything you wanted to know about modern network congestion control but were perhaps too afraid to ask

    In which a little unfairness can be quite beneficial

    Systems Approach It’s hard not to be amazed by the amount of active research on congestion control over the past 30-plus years. From theory to practice, and with more than its fair share of flame wars, the question of how to manage congestion in the network is a technical challenge that resists an optimal solution while offering countless options for incremental improvement.

    This seems like a good time to take stock of where we are, and ask ourselves what might happen next.

    Congestion control is fundamentally an issue of resource allocation — trying to meet the competing demands that applications have for resources (in a network, these are primarily link bandwidth and router buffers), which ultimately reduces to deciding when to say no and to whom. The best framing of the problem I know traces back to a paper [PDF] by Frank Kelly in 1997, when he characterized congestion control as “a distributed algorithm to share network resources among competing sources, where the goal is to choose source rate so as to maximize aggregate source utility subject to capacity constraints.”

  • How business makes streaming faster and cheaper with CDN and HESP support

    Ensure a high video streaming transmission rate

    Paid Post Here is everything about how the HESP integration helps CDN and the streaming platform by G-Core Labs ensure a high video streaming transmission rate for e-sports and gaming, efficient scalability for e-learning and telemedicine and high quality and minimum latencies for online streams, media and TV broadcasters.

    HESP (High Efficiency Stream Protocol) is a brand new adaptive video streaming protocol. It allows delivery of content with latencies of up to 2 seconds without compromising video quality and broadcasting stability. Unlike comparable solutions, this protocol requires less bandwidth for streaming, which allows businesses to save a lot of money on delivery of content to a large audience.

    Since HESP is based on HTTP, it is suitable for video transmission over CDNs. G-Core Labs was among the world’s first companies to have embedded this protocol in its CDN. With 120 points of presence across 5 continents and over 6,000 peer-to-peer partners, this allows a service provider to deliver videos to millions of viewers, to any devices, anywhere in the world without compromising even 8K video quality. And all this comes at a minimum streaming cost.
