Unable to load bpf program that define BPF_MAP_TYPE_ARRAY

[ChrsMark]

Hi!

I'm having issues while trying to load BPF program that defines a BPF_MAP_TYPE_ARRAY. I'm getting the following error when trying to call

gobpf/elf/elf.go

Line 497 in 2289761

func (b *Module) Load(parameters map[string]SectionParams) error {

:

error while loading map "maps/count_map": operation not permitted

I'm running on Ubuntu machine on GCP:

cat /etc/os-release
NAME="Ubuntu"
VERSION="20.04.2 LTS (Focal Fossa)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 20.04.2 LTS"
VERSION_ID="20.04"
HOME_URL="https://www.ubuntu.com/"
SUPPORT_URL="https://help.ubuntu.com/"
BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/"
PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy"
VERSION_CODENAME=focal
UBUNTU_CODENAME=focal

I can provide more info if needed but wondering if this is something obvious that I'm missing on my system.

Thanks!

Update:

It seems that it fails at

gobpf/elf/elf.go

Line 94 in b5e5715

ret = syscall(__NR_bpf, BPF_MAP_CREATE, &attr, sizeof(attr));

and even setting the limit to unlimited with ulimit -a unlimited it doesn't fix the issue. Running with sudo doesn't help too.
