[PATCH bpf 0/5] bpf: fix map permissions check and cleanup code around

From: Anton Protopopov
Date: Wed May 27 2020 - 14:57:37 EST


This series fixes a bug in the map_lookup_and_delete_elem() function which
should check for the FMODE_CAN_READ bit, because it returns data to user space.
The rest of commits fix some typos and comment in selftests and extend the
test_map_wronly test to cover the new check for the BPF_MAP_TYPE_STACK and
BPF_MAP_TYPE_QUEUE map types.

Anton Protopopov (5):
selftests/bpf: fix a typo in test_maps
selftests/bpf: cleanup some file descriptors in test_maps
selftests/bpf: cleanup comments in test_maps
bpf: fix map permissions check
selftests/bpf: add tests for write-only stacks/queues
