Subject: pull-request: bpf-next 2021-04-28
Hi David, hi Jakub,
The following pull-request contains BPF updates for your *net-next* tree.
We've added 19 non-merge commits during the last 2 day(s) which contain
a total of 36 files changed, 494 insertions(+), 313 deletions(-).
The main changes are:
1) Add link detach and following re-attach for trampolines, from Jiri Olsa.
2) Use kernel's "binary printf" lib for formatted output BPF helpers (which
avoids the needs for variadic argument handling), from Florent Revest.
3) Fix verifier 64 to 32 bit min/max bound propagation, from Daniel Borkmann.
4) Convert cpumap to use netif_receive_skb_list(), from Lorenzo Bianconi.
5) Add generic batched-ops support to percpu array map, from Pedro Tammela.
6) Various CO-RE relocation BPF selftests fixes, from Andrii Nakryiko.
7) Misc doc rst fixes, from Hengqi Chen.
