Lots of core UNIX and Linux projects are. C++ is not liked by a lot of low level FOSS community. I think Rust is going to get further into these areas. I know C++ well but prefer C. I know plenty of others who feel the same.
”C++ is a horrible language. It’s made more horrible by the fact that a lot
of substandard programmers use it, to the point where it’s much much
easier to generate total and utter crap with it. Quite frankly, even if
the choice of C were to do nothing but keep the C++ programmers out,
that in itself would be a huge reason to use C.”
Torvalds just really dislikes C++. He’s gone on the record saying that he thinks it’s just not a good language. In his own words “C++ is just a waste, there is no design at all, just adding some scum on top of C.”
The STD is maybe the only good thing C++ has over C, and even that is awful compared to other language’s standard libraries.
I can’t name another good thing C++ has. Maybe templates. C++’s reliance on inheritance for polymorphism is awful (should’ve gone with interfaces/traits).
Not to mention the mess with all the different types of constructors that must always be implemented.
It’s just a bunch of bad design choices added on top of an old outdated language.
Is there some lore about this I don’t know?
There is no C++ allowed in the Linux kernel and Linus has gone on several major rants about how terrible a language it is.
Is it all C?
There’s assembly and makefiles too
Less of a joke answer, there has been work to allow Rust bindings for drivers.
According to the github analysis, the kernel repository is:
So yeah, its basically all C, plus a tiny bit of assembly for very low level bootstrapping and some helper scripts.

I’ve read that they are writing parts of the kernel in Rust
Yes, I think Rust is a better C++ and will replace it in many places. Though all three will be around for ever to be honest.
Yes, first Rust code was released in 6.6 I think and MS also started implementing Rust code in the Windows kernel.
Rust is certainly interesting. I think it’s the C++ we need.
Linus is a C advocate btw, which make him even more goated

he’s not wrong
In the specific use case of kernel programming, maybe. But the Standard Template Library is awesome.
