PSA: everybody should set their #git conflictstyle to diff3 or zdiff3:

git config --global merge.conflictStyle diff3

I have no idea why this isn't already the default. Without this, you have no idea what the actual conflict is.

Meaning of the conflict markers:

<<<<<<<
this is what is in your current tree before cherry-picking
|||||||
this is what the patch expected to find there

this is what the patch wants it to be after being applied
>>>>>>>

diff3 basically adds the middle part.

Yay, I just submitted a Sphinx extension that adds translation links to the top of the kernel docs where translations exist: https://lore.kernel.org/linux-doc/20231028162931.261843-1-vegard.nossum@oracle.com/

...that said, I do wonder if machine translations are good enough at this point that you can just do it on the fly.

Somebody made a programming language for NES games:

Honestly looks pretty cool.

Civil Infrastructure Platform to maintain 6.1 for 10 years: https://lwn.net/Articles/947606/

There are still things I don't understand, like how this is an official LF project, yet the SLTS kernels are not official stable (kernel.org) kernels. And Greg KH who maintains those official stable kernels is also working for LF and simultaneously completely against what CIP is doing: https://lore.kernel.org/all/Yvo2TnrUGoLKEY+v@kroah.com/ 🤨

I was thinking that #LinuxKernel subsystems should all have review checklists or guidelines that are specific to their subsystem, just the kind of small bits of info that reviewers who know the subsystem will always check for.

So far I only found these for KVM (https://docs.kernel.org/virt/kvm/review-checklist.html) and RCU (https://docs.kernel.org/RCU/checklist.html) -- are there others?

It seems like such an obvious thing to have, as it should help both patch authors and reviewers (especially new reviewers) and document subsystem specifics.

Visa card declined by Amazon for a 10 euro purchase using stored card details that have been used many times before. Bank says the error message on their end indicates an incorrect cryptogram (security code on the back of the card). I re-added the card and even successfully verified the purchase using 2FA with my bank's phone app and it still comes back as declined the next day.

Anybody have ideas on what could be going wrong here?

Edit: balance is positive... not hitting limits either...

Heh, apparently Red Hat recently assigned a CVE for a random kernel fix I did 7 years ago: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-3106

I honestly don't really remember the context but I'm pretty sure this was found with an AFL-based netlink fuzzer (unprivileged).

I'd be curious to know how they came across this now and what sort of analysis they based the CVE request on. I'm not saying it's wrong, but it's odd to dig something that old up so I have to wonder "why now?"
