Project mention: OpenSSL bug exposed up to 255 bytes of server heap and existed since 2011 | news.ycombinator.com | 2024-07-30
I started writing s2n the day after Heartbleed and the first lines of code were for the stuffer interface. A stuffer is a buffer for stuff, and it's like Java buffered I/O for C. You can get a flavor from reading the header: https://github.com/aws/s2n-tls/blob/main/stuffer/s2n_stuffer...
The implementation is incredibly simple. Treat all blocks of memory as blob with a known size and then read/write into those blobs with a cursor to track progress and bounds checks on every access. Fence all serialization/deserialization through a safe low level interface. Not only do you get memory safety (which we later proved using formal reasoning) ... but when you're parsing message formats it lends itself to a declarative coding style that makes it very clear what the structure is. You can also do lifecycle things, like erasing sensitive memory with zeroes when you're done with it, making sure things don't show up in core dumps, etc. BoringSSL introduced a Crypto_bytes API that also did some of this plus bounds checking, and retrofit it into OpenSSL.
OpenSSL on the other hand is a horrific mash up of raw pointer arithmetic, ad-hoc parsers interleaved with business logic and control flow. I could never keep it straight, and it always scared me to review.

> QBE is a new optimizing backend much simpler than LLVM; cproc and cparser are two of the C compilers that target it, in addition to its own minic.
I thought cparser targeted libFirm. That's what their GitHub page says [0].
"It acts as a frontend to the libFirm intermediate representation library."
> We really need a production quality open source C compiler that is actually written in C.
I honestly think cproc or cparser are almost there already. For cproc, you just need to improve the quality of code optimization; it's really QBE you'd need to change. For example, you could change unnecessary multiplications by powers of 2 into left shifts, improve instruction selection so that subtraction is always something like "sub rax, rdi" and not "neg rdi / add rax, rdi" [1]).
For cparser, I notice slightly higher quality codegen; libFirm just needs more architecture support (e.g. AMD64 support appears to work for me, but it's labeled as experimental).

[1]: I'm pretty sure this is the line of code that generates it, too: https://c9x.me/git/qbe.git/tree/amd64/emit.c#n418
