This commit adds BPF helper functions needed by tests in a new library.
It defines new functions that allow verifying BPF map meta-data from
the procfs as well as using the bpf() system call with
BPF_OBJ_GET_INFO_BY_FD. It is necessary to verify from procfs and using
BPF_OBJ_GET_INFO_BY_FD because the information available from both
these places is disjoint (for example, checking whether a map is frozen
cannot be performed with BPF_OBJ_GET_INFO_BY_FD).
Source files modified:
* test/zdtm/lib/Makefile - Generating build artifacts
Source files added:
* test/zdtm/lib/bpfmap_zdtm.c - Provides definitions for 3 new
functions:
(a) parse_bpfmap_fdinfo() - Parses information about the BPF map
from procfs
(b) cmp_bpf_map_info() - Compares the attributes of a BPF map file
obtained from BPF_OBJ_GET_INFO_BY_FD. This function is typically
used to verify that the attributes of a BPF map remain the same
before checkpoint and after restore
(c) cmp_bpfmap_fdinfo() - Compares the attributes of a BPF map file
obtained from procfs. This function is typically used to verify
that the attributes of a BPF map remain the same before checkpoint
and after restore
* test/zdtm/lib/bpfmap_zdtm.h - Structure and function declarations.
Declares struct bpfmap_fdinfo_obj, which stores information about BPF
maps parsed from procfs
