Subject: [PATCH bpf-next 0/5] Fix BPF probe memory helpers
Date: Fri, 25 Oct 2019 18:37:06 +0200 [thread overview]
Message-ID: <cover.1572010897.git.daniel@iogearbox.net> (raw)
This set adds probe_read_{user,kernel}(), probe_read_str_{user,kernel}()
helpers, fixes probe_write_user() helper and selftests. For details please
see individual patches.
Thanks!
Daniel Borkmann (5):
uaccess: Add non-pagefault user-space write function
bpf: Make use of probe_user_write in probe write helper
bpf: Add probe_read_{user,kernel} and probe_read_str_{user,kernel} helpers
bpf, samples: Use bpf_probe_read_user where appropriate
bpf, testing: Add selftest to read/write sockaddr from user space
