Subject: pull-request: bpf-next 2019-05-31
Hi David,
The following pull-request contains BPF updates for your *net-next* tree.
Lots of exciting new features in the first PR of this developement cycle!
The main changes are:
1) misc verifier improvements, from Alexei.
2) bpftool can now convert btf to valid C, from Andrii.
3) verifier can insert explicit ZEXT insn when requested by 32-bit JITs.
This feature greatly improves BPF speed on 32-bit architectures. From Jiong.
4) cgroups will now auto-detach bpf programs. This fixes issue of thousands
bpf programs got stuck in dying cgroups. From Roman.
5) new bpf_send_signal() helper, from Yonghong.
6) cgroup inet skb programs can signal CN to the stack, from Lawrence.
7) miscellaneous cleanups, from many developers.
Please consider pulling these changes from:
git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next.git
Thanks a lot!
