Michal Rostecki 78e58b8960 bpf(helpers): Add *_str_bytes helpers ... This change adds two new helpers: * bpf_probe_read_user_str_bytes * bpf_probe_read_kernel_str_bytes Those new helpers are returning a bytes slice (`&[u8]`) with a length equal to the length of probed, null-terminated string. When using those helpers, users don't have to manually check for length and create such slices themselves. They also make converting to `str` way more convenient, for example: ```rust let my_str = unsafe { core::str::from_utf8_unchecked( bpf_probe_read_user_str_bytes(user_ptr, &mut buf)? ) }; ``` This change also deprecates the old helpers, since their names are confusing (they have nothing to do with Rust `str`) and using them requires writing boilerplate code (for checking the length and making eBPF verifier happy): * bpf_probe_read_user_str * bpf_probe_read_kernel_str Tested on: 516b29af68 Signed-off-by: Michal Rostecki <vadorovsky@gmail.com>		3 years ago
