monsieuriconx.x.x.x - - [10/Nov/2024:00:02:37 +0000] "GET / HTTP/1.1" 301 162 "-" "okhttp/4.9.0"
You know what’s interesting about this log line? It repeats 56,686,963 times in www.kernel.org logs for yesterday, across 4 nodes. That’s about 700 times a second, and this has been going on for months.
These requests aren’t intentionally malicious – they issue a simple GET /, receive their 301 redirect, and terminate the connection. From what I can tell, this is some kind of appliance or software installed on mobile clients that uses “can I reach www.kernel.org” as a network test.
This wouldn’t be that big of a deal – a single plaintext “GET /“ that triggers an immediate 301 is very cheap for us to generate, but the number of these requests has been steadily growing.
If you have any idea what this is and how to make it stop, please reach out?

karen@floss.socialOutreachy is getting squeezed financially from reduced funding related to diversity programs and reduced funding for open source orgs. Can you help us spread the word about how important the program is and help us connect to folks who might contribute funding?

ljsNot going to dictate to you who to vote for but obviously I think there's only one sane choice and she's called Kamala Harris.
Even if you don't much like her, her party, or her policies, the alternative is so deeply shit and depressing just swallow your pride and do it.
If you do like her/her party/her policies then vote for her.
(yeah I lied I am dictating the choice sorry not sorry)
But either way GO AND VOTE!
Trump will concede the war in Ukraine to Russia, and if they win there, next he will attack a NATO country. Think about that. The people there fight for all of us.
The (alleged) greatest fraudster in modern history (+ alleged traitor to his own country and allegedly regularly in contact with Putin) Musk will be given a total reprieve and control of part of the US govt.
And this of course is far from the only issue that utter orange moron will wreak havoc upon.
GET UP.
GO VOTE.

hyeyooA note for the next time I forget:
Context is switched from one kernel context to another. When a user process is going to be rescheduled, it first switches from user context to its kernel context after storing the registers on the kernel stack (pt_regs) due to a scheduler tick.
When switching between kernel contexts, only callee-saved registers are restored (from cpu_context in thread_struct), as the other registers should have been stored on the kernel stack (by the calling convention) before calling __switch_to()->cpu_switch_to() (on ARM64).
