[PATCHv3 bpf 0/3] Fix pining maps after reuse map fd

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When a user reuse map fd after creating a map manually and set the
pin_path, then load the object via libbpf. bpf_object__create_maps()
will skip pinning map if map fd exist. Fix it by add moving bpf creation
to else condition and go on checking map pin_path after that.

v3:
for selftest: use CHECK() for bpf_object__open_file() and close map fd on error

v2:
a) close map fd if init map slots failed
b) add bpf selftest for this scenario


Hangbin Liu (3):
  libbpf: close map fd if init map slots failed
  libbpf: check if pin_path was set even map fd exist
  selftest/bpf: test pinning map with reused map fd
