What kind of events were being lost, and under what conditions? I'd like to see if it can be fixed.

Above two comments are very helpful, thanks. I've corrected the -m32 issue. And thanks for pointing out the x86/ABI assumptions. Had not considered that. It's certainly interesting…

I think it has to keep it for externally visible functions, right?

BPF_PROG_RUN is great but unfortunately depends on the running kernel version. To that end, I wrote `vmtest` ( https://dxuuu.xyz/vmtest.html ) which is designed for the BPF_PROG_RU…

I use stock ios and mobius sync works pretty well. No issues so far over 1y+ of use.

Was threading support ever added? I recall there being a few attempts. I tried aerc out for quite a bit but ultimately had to give it up for neomutt b/c mailing list discussions we…

Are there any docs for how it's implemented?

Completely agree. FWIW, I think procedural macros make a huge difference for ergonomics. For example, a "similar" library in C++ (libcereal) is still a PITA to use and debug.

Because you can’t add a feature with a knob. And not all changes can be made in a module (eg core kernel). And even if they could, kernel internals are not stable and you would sti…

Your metabolism can change during your life. Different people can also have different metabolisms.

Both parts (compiler backends & fuzzing) are immensely complicated stuff on their own. I can only imagine the trickery and head scratching that comes with the combination. I’ve wor…

Yes, exactly. > It looks like systemd-oomd is related to (based on? from the same people as?) Facebook's oomd Yep, I authored the original standalone oomd (along with many others' …

When a cgroup hits its memory.max the kernel OOM killer is invoked. systemd-oomd enables finer grained policy than the kernel OOM killer. systemd-oomd can also prevent livelocks (w…

A possibly lighter weight alternative is libbpf-rs [0]. libbpf-rs is designed to take advantage of BPF's Compile-Once-Run-Everywhere functionality where you can ship a pre-compiled…
