Hi David, The following pull-request contains BPF updates for your *net* tree.
The main changes are: 1) Fix BPF prog kallsyms and bpf_prog_get_info_by_fd() jited address export to not use page start but actual start instead to work correctly with profiling e.g. finding hot instructions from stack traces. Also fix latter with regards to dumping address and jited len for !multi prog, from Song. 2) Fix bpf_prog_get_info_by_fd() for !root to zero info.nr_jited_func_lens instead of leaving the user provided length, from Daniel. Please consider pulling these changes from: git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf.git Thanks a lot! ---------------------------------------------------------------- The following changes since commit 7de414a9dd91426318df7b63da024b2b07e53df5: net: drop skb on failure in ip_check_defrag() (2018-11-01 13:55:30 -0700) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf.git for you to fetch changes up to 28c2fae726bf5003cd209b0d5910a642af98316f: bpf: fix bpf_prog_get_info_by_fd to return 0 func_lens for unpriv (2018-11-02 13:51:15 -0700) ---------------------------------------------------------------- Daniel Borkmann (2): Merge branch 'bpf-accurate-prog-addr' bpf: fix bpf_prog_get_info_by_fd to return 0 func_lens for unpriv Song Liu (3): bpf: show real jited prog address in /proc/kallsyms bpf: show real jited address in bpf_prog_info->jited_ksyms bpf: show main program address and length in bpf_prog_info kernel/bpf/core.c | 4 +--- kernel/bpf/syscall.c | 35 +++++++++++++++++++++++++---------- 2 files changed, 26 insertions(+), 13 deletions(-)
