2020-06-01bpf, selftests: Add sk_msg helpers load and attach testJohn Fastabend
The test itself is not particularly useful but it encodes a common pattern we have. Namely do a sk storage lookup then depending on data here decide if we need to do more work or alternatively allow packet to PASS. Then if we need to do more work consult task_struct for more information about the running task. Finally based on this additional information drop or pass the data. In this case the suspicious check is not so realisitic but it encodes the general pattern and uses the helpers so we test the workflow. This is a load test to ensure verifier correctly handles this case.

2020-06-01bpf: Extend bpf_base_func_proto helpers with probe_* and *current_task*John Fastabend
Often it is useful when applying policy to know something about the task. If the administrator has CAP_SYS_ADMIN rights then they can use kprobe + networking hook and link the two programs together to accomplish this. However, this is a bit clunky and also means we have to call both the network program and kprobe program when we could just use a single program and avoid passing metadata through sk_msg/skb->cb, socket, maps, etc. To accomplish this add probe_* helpers to bpf_base_func_proto programs guarded by a perfmon_capable() check. New supported helpers are the following, BPF_FUNC_get_current_task BPF_FUNC_probe_read_user BPF_FUNC_probe_read_kernel BPF_FUNC_probe_read_user_str BPF_FUNC_probe_read_kernel_str Signed-off-by: John Fastabend <john.fastabend@gmail.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Yonghong Song <yhs@fb.com> Link: https://lore.kernel.org/bpf/159033905529.12355.4368381069655254932.stgit@john-Precision-5820-Tower Signed-off-by: Alexei Starovoitov <ast@kernel.org>

2020-06-01tools, bpftool: Make capability check account for new BPF capsQuentin Monnet
Following the introduction of CAP_BPF, and the switch from CAP_SYS_ADMIN to other capabilities for various BPF features, update the capability checks (and potentially, drops) in bpftool for feature probes. Because bpftool and/or the system might not know of CAP_BPF yet, some caution is necessary: - If compiled and run on a system with CAP_BPF, check CAP_BPF, CAP_SYS_ADMIN, CAP_PERFMON, CAP_NET_ADMIN. - Guard against CAP_BPF being undefined, to allow compiling bpftool from latest sources on older systems. If the system where feature probes are run does not know of CAP_BPF, stop checking after CAP_SYS_ADMIN, as this should be the only capability required for all the BPF probing. - If compiled from latest sources on a system without CAP_BPF, but later executed on a newer system with CAP_BPF knowledge, then we only test CAP_SYS_ADMIN. Some probes may fail if the bpftool process has CAP_SYS_ADMIN but misses the other capabilities. The alternative would be to redefine the value for CAP_BPF in bpftool, but this does not look clean, and the case sounds relatively rare anyway. Note that libcap offers a cap_to_name() function to retrieve the name of a given capability (e.g. "cap_sys_admin"). We do not use it because deriving the names from the macros looks simpler than using cap_to_name() (doing a strdup() on the string) + cap_free() + handling the case of failed allocations, when we just want to use the name of the capability in an error message. The checks when compiling without libcap (i.e. root versus non-root) are unchanged. v2: - Do not allocate cap_list dynamically. - Drop BPF-related capabilities when running with "unprivileged", even if we didn't have the full set in the first place (in v1, we would skip dropping them in that case). - Keep track of what capabilities we have, print the names of the missing ones for privileged probing. - Attempt to drop only the capabilities we actually have. - Rename a couple variables.

2020-06-01tools, bpftool: Clean subcommand help messagesQuentin Monnet
This is a clean-up for the formatting of the do_help functions for bpftool's subcommands. The following fixes are included: - Do not use argv[-2] for "iter" help message, as the help is shown by default if no "iter" action is selected, resulting in messages looking like "./bpftool bpftool pin...". - Do not print unused HELP_SPEC_PROGRAM in help message for "bpftool link". - Andrii used argument indexing to avoid having multiple occurrences of bin_name and argv[-2] in the fprintf() for the help message, for "bpftool gen" and "bpftool link". Let's reuse this for all other help functions. We can remove up to thirty arguments for the "bpftool map" help message. - Harmonise all functions, e.g. use ending quotes-comma on a separate line.
