Re: [PATCH bpf-next v4 1/2] bpftool: Use appropriate permissions for map access

2025-06-21 01:18 UTC+1000 ~ Slava Imameev slava.imameev@crowdstrike.com

Modify several functions in tools/bpf/bpftool/common.c to allow specification of requested access for file descriptors, such as read-only access.

Update bpftool to request only read access for maps when write access is not required. This fixes errors when reading from maps that are protected from modification via security_bpf_map.
