Hi David,
The following pull-request contains BPF updates for your *net* tree.
We've added 3 non-merge commits during the last 4 day(s) which contain
a total of 4 files changed, 25 insertions(+), 20 deletions(-).
The main changes are:
1) Explicitly memset the bpf_attr structure on bpf() syscall to avoid
having to rely on compiler to do so. Issues have been noticed on
some compilers with padding and other oddities where the request was
then unexpectedly rejected, from Greg Kroah-Hartman.
2) Sanitize the bpf_struct_ops TCP congestion control name in order to
avoid problematic characters such as whitespaces, from Martin KaFai Lau.
