Daniel Borkmann says: ==================== pull-request: bpf-next 2020-11-14 1) Add BTF generation for kernel modules and extend BTF infra in kernel e.g. support for split BTF loading and validation, from Andrii Nakryiko. 2) Support for pointers beyond pkt_end to recognize LLVM generated patterns on inlined branch conditions, from Alexei Starovoitov. 3) Implements bpf_local_storage for task_struct for BPF LSM, from KP Singh. 4) Enable FENTRY/FEXIT/RAW_TP tracing program to use the bpf_sk_storage infra, from Martin KaFai Lau. 5) Add XDP bulk APIs that introduce a defer/flush mechanism to optimize the XDP_REDIRECT path, from Lorenzo Bianconi. 6) Fix a potential (although rather theoretical) deadlock of hashtab in NMI context, from Song Liu. 7) Fixes for cross and out-of-tree build of bpftool and runqslower allowing build for different target archs on same source tree, from Jean-Philippe Brucker. 8) Fix error path in htab_map_alloc() triggered from syzbot, from Eric Dumazet. 9) Move functionality from test_tcpbpf_user into the test_progs framework so it can run in BPF CI, from Alexander Duyck. 10) Lift hashtab key_size limit to be larger than MAX_BPF_STACK, from Florian Lehner. Note that for the fix from Song we have seen a sparse report on context imbalance which requires changes in sparse itself for proper annotation detection where this is currently being discussed on linux-sparse among developers [0]. Once we have more clarification/guidance after their fix, Song will follow-up.
