Patch #1 fixes the out-of-bound for sockmap link fdinfo. Patch #2 fixes the kmemleak report when parsing the mount options for bpffs. Patch #3~#7 fix issues related to bits iterator. Please check the individual patches for more details. And comments are always welcome. Hou Tao (7): bpf: Add the missing BPF_LINK_TYPE invocation for sockmap bpf: Preserve param->string when parsing mount options bpf: Free dynamically allocated bits in bpf_iter_bits_destroy() bpf: Check the validity of nr_words in bpf_iter_bits_new() bpf: Change the type of unsafe_ptr in bpf_iter_bits_new() selftests/bpf: Test multiplication overflow of nr_bits in bits_iter selftests/bpf: Pass a pointer of unsigned long to bpf_iter_bits_new() include/linux/bpf_types.h | 1 + include/uapi/linux/bpf.h | 3 ++ kernel/bpf/helpers.c | 30 +++++++++----- kernel/bpf/inode.c | 5 ++- .../selftests/bpf/progs/verifier_bits_iter.c | 40 +++++++++++++------ 5 files changed, 54 insertions(+), 25 deletions(-)
