Also, allow the bpf programs to use the get_current_uid_gid helper meaning socket marks, priority and device can be set based on the uid/gid of the running process. Sample programs are updated to demonstrate the new options. v3 - no changes to Patches 1 and 2 which Alexei acked in previous versions - dropped change related to recursive programs in a cgroup - updated tests per dropped patch v2 - added flag to control recursive behavior as requested by Alexei - added comment to sock_filter_func_proto regarding use of get_current_uid_gid helper - updated test programs for recursive option David Ahern (7): bpf: Add mark and priority to sock options that can be set bpf: Allow cgroup sock filters to use get_current_uid_gid helper samples/bpf: Update sock test to allow setting mark and priority samples/bpf: Add detach option to test_cgrp2_sock samples/bpf: Add option to dump socket settings samples/bpf: Update cgrp2 socket tests samples/bpf: Update cgroup socket examples to use uid gid helper include/uapi/linux/bpf.h | 2 + net/core/filter.c | 42 ++++++- samples/bpf/sock_flags_kern.c | 5 + samples/bpf/test_cgrp2_sock.c | 255 ++++++++++++++++++++++++++++++++++++----- samples/bpf/test_cgrp2_sock.sh | 162 ++++++++++++++++++++------ 5 files changed, 401 insertions(+), 65 deletions(-) -- 2.1.4
