Daniel Borkmann says: ==================== pull-request: bpf 2021-10-07 We've added 7 non-merge commits during the last 8 day(s) which contain a total of 8 files changed, 38 insertions(+), 21 deletions(-). The main changes are: 1) Fix ARM BPF JIT to preserve caller-saved regs for DIV/MOD JIT-internal helper call, from Johan Almbladh. 2) Fix integer overflow in BPF stack map element size calculation when used with preallocation, from Tatsuhiko Yasumatsu. 3) Fix an AF_UNIX regression due to added BPF sockmap support related to shutdown handling, from Jiang Wang. 4) Fix a segfault in libbpf when generating light skeletons from objects without BTF, from Kumar Kartikeya Dwivedi. 5) Fix a libbpf memory leak in strset to free the actual struct strset itself, from Andrii Nakryiko. 6) Dual-license bpf_insn.h similarly as we did for libbpf and bpftool, with ACKs from all contributors, from Luca Boccassi. ==================== Link: https://lore.kernel.org/r/20211007135010.21143-1-daniel@iogearbox.net Signed-off-by: Jakub Kicinski <kuba@kernel.org>
