map: replace hacky unsafe.Pointer conversion with PROT_NONE page

1

One of our legacy code paths currently does a dodgy pointer conversion: unsafe.Pointer(^uintptr(0)) This is (correctly) flagged by linters as being a bit bogus, since unsafe.Pointer conversions do have an...

The BPF uapi uses a special type `__aligned_u64` to store pointers: ```C struct { /* anonymous struct used by BPF_OBJ_* commands */ __aligned_u64 pathname; __u32 bpf_fd; __u32 file_flags; }; ```...

This input parsed as C ``` #if defined(FOO) #define BAR // comment #endif ``` matches the following query: ``` $ cat q.txt (translation_unit (preproc_if . condition: (_) @cond . (preproc_def)+...

We currently require a v4.19 or equivalent kernel. This locks us out of many important improvements like higher complexity limits, deadcode elimination and so on. We propose to raise the...

Semaphore 2.0 doesn't give free builds to organisations

Seems like only individuals get 20$ in free builds per month. I've contacted Semaphore support to see if there is some option for open source projects.

Add functions to check ABI of eBPF collection

It's useful to do some basic checks on a Collection if there is a user space component. Basically, let the user specific a list of MapSpec and make sure that...

proposal: remove partial 32bit support

2

We don't have a way of testing 32bit support (not available on Semaphore) and it's probably not really used anyway. I think we should remove it. Thoughts @nathanjsweet ?

BPF_PROG_TEST_RUN does not reset output buffer on each run

1

It's very easy to mess up benchmarks when using Program.Benchmark, since the kernel feeds the output from benchmark run N to run N+1. This means we don't measure the exact...
