[PATCH bpf-next 00/17] bpf: net: Remove duplicated code from bpf_getsockopt()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The earlier commits [0] removed duplicated code from bpf_setsockopt().
This series is to remove duplicated code from bpf_getsockopt().

Unlike the setsockopt() which had already changed to take
the sockptr_t argument, the same has not been done to
getsockopt().  This is the extra step being done in this
series.

  bpf: net: Change do_tcp_getsockopt() to take the sockptr_t argument
  bpf: net: Avoid do_tcp_getsockopt() taking sk lock when called from
    bpf
  bpf: net: Change do_ip_getsockopt() to take the sockptr_t argument
  bpf: net: Avoid do_ip_getsockopt() taking sk lock when called from bpf
  net: Remove unused flags argument from do_ipv6_getsockopt
  net: Add a len argument to compat_ipv6_get_msfilter()
  bpf: net: Change do_ipv6_getsockopt() to take the sockptr_t argument

    bpf
  bpf: Embed kernel CONFIG check into the if statement in bpf_getsockopt
  bpf: Change bpf_getsockopt(SOL_SOCKET) to reuse sk_getsockopt()
  bpf: Change bpf_getsockopt(SOL_TCP) to reuse do_tcp_getsockopt()
  bpf: Change bpf_getsockopt(SOL_IP) to reuse do_ip_getsockopt()
