Hi David,
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Sanitize attr->{prog,map}_type from bpf(2) since used as an array index
to retrieve prog/map specific ops such that we prevent potential out of
bounds value under speculation, from Mark and Daniel.
Please consider pulling these changes from:
git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf.git
Thanks a lot!
