Add a new "bpftool prog run" subcommand to run a loaded program on input
data (and possibly with input context) passed by the user.
Print output data (and output context if relevant) into a file or into
the console. Print return value and duration for the test run into the
console.
A "repeat" argument can be passed to run the program several times in a
row.
The command does not perform any kind of verification based on program
type (Is this program type allowed to use an input context?) or on data
consistency (Can I work with empty input data?), this is left to the
kernel.
Example invocation:
# perl -e 'print "\x0" x 14' | ./bpftool prog run \
pinned /sys/fs/bpf/sample_ret0 \
data_in - data_out - repeat 5
0000000 0000 0000 0000 0000 0000 0000 0000 | ........ ......
Return value: 0, duration (average): 260ns
When one of data_in or ctx_in is "-", bpftool reads from standard input,
in binary format. Other formats (JSON, hexdump) might be supported (via
an optional command line keyword like "data_fmt_in") in the future if
relevant, but this would require doing more parsing in bpftool.
v2:
- Fix argument names for function check_single_stdin(). (Yonghong)
