Subject: [bpf-next PATCH 0/3] bpf: Add sk_msg helpers
Date: Wed, 13 May 2020 12:23:32 -0700 [thread overview]
Message-ID: <158939776371.17281.8506900883049313932.stgit@john-Precision-5820-Tower> (raw)
This series adds helpers for sk_msg program type.
Add a set of helpers that makes sk_msg more useful. Notable add the
*current_task* getters and the probe_* routines guarded by a capabilities
check for CAP_SYS_ADMIN.
BPF_FUNC_perf_event_output
BPF_FUNC_get_current_uid_gid
BPF_FUNC_get_current_pid_tgid
BPF_FUNC_get_current_cgroup_id
BPF_FUNC_get_current_ancestor_cgroup_id
BPF_FUNC_get_cgroup_classid
BPF_FUNC_get_current_task
BPF_FUNC_current_task_under_cgroup
BPF_FUNC_probe_read_user
BPF_FUNC_probe_read_kernel
BPF_FUNC_probe_read
BPF_FUNC_probe_read_user_str
BPF_FUNC_probe_read_kernel_str
BPF_FUNC_probe_read_str
BPF_FUNC_sk_storage_get
BPF_FUNC_sk_storage_delete
I have an RFC test for sk_storage_* patch that is pending merge of
other sockmap_test patches.
