    net: ptp: use sk_unattached_filter_create() for BPF · e62d2df0
    Daniel Borkmann 提交于
    This patch migrates an open-coded sk_run_filter() implementation with
    proper use of the BPF API, that is, sk_unattached_filter_create(). This
    migration is needed, as we will be internally transforming the filter
    to a different representation, and therefore needs to be decoupled.
    
    It is okay to do so as skb_timestamping_init() is called during
    initialization of the network stack in core initcall via sock_init().
    This would effectively also allow for PTP filters to be jit compiled if
    bpf_jit_enable is set.
    
    For better readability, there are also some newlines introduced, also
    ptp_classify.h is only in kernel space.
    
    Joint work with Alexei Starovoitov.
