Hi David, hi Jakub, hi Paolo, hi Eric,
The following pull-request contains BPF updates for your *net* tree.
We've added 5 non-merge commits during the last 20 day(s) which contain
a total of 6 files changed, 34 insertions(+), 12 deletions(-).
The main changes are:
1) Fix xsk sockets when rx and tx are separately bound to the same umem, also
fix xsk copy mode combined with busy poll, from Maciej Fijalkowski.
2) Fix BPF tunnel/collect_md helpers with bpf_xmit lwt hook usage which triggered
a crash due to invalid metadata_dst access, from Eyal Birger.
3) Fix release of page pool in XDP live packet mode, from Toke Høiland-Jørgensen.
4) Fix potential NULL pointer dereference in kretprobes, from Adam Zabrocki.
(Masami & Steven preferred this small fix to be routed via bpf tree given it's
follow-up fix to Masami's rethook work that went via bpf earlier, too.)
