QUESTION

eBPF, track values longer than stack size?

Asked 2019-Mar-07 at 17:02

I'm extending a program which take arguments of traced function and print it. Everything works fine with numeric arguments and short strings. But it's not clear how to handle with long string that longer than stack size in eBPF (which is limited with 512 byte).

In example below, string is limited by 80 bytes, of course it can be increased up to 512, but how to track more longer strings?

Example of C program with traced function which called "ameba"

I read about BPF_MAP_TYPE_PERCPU_ARRAY could help in such case, but it's not clear for me how to use it.

You're right. Peeps usually rely on per-cpu arrays to overcome stack size limitations. The following implements that sort of solution, whereby I'm using a per-cpu array to store struct ameba_event_t instead of storing it on the stack.

I think you're going to need Linux v4.18 to be able to do this (you need commit d71962f). I haven't tested the code as I don't have the right setup at hand, but can later if you run into any issue.

QUESTION

golang, ebpf and functions duration

Asked 2019-Mar-07 at 17:02

I'm playing with gobpf and have got an issue with calculating a duration of traced user-space function. I use bpf_ktime_get_ns() to read time and then trying to calculate delta, but got enormous numbers, though traced function sleeps just 1 second.

Here is the tested C-program, which has a function called "ameba".

This looks like it is caused by a mismatch of paddings between kernel and user sides. The data_t structure is actually padded at compile-time to be equivalent to the following:
