====================
pull-request: bpf 2018-02-20

The following pull-request contains BPF updates for your *net* tree.

The main changes are:

1) Fix a memory leak in LPM trie's map_free() callback function, where
   the trie structure itself was not freed since initial implementation.
   Also a synchronize_rcu() was needed in order to wait for outstanding
   programs accessing the trie to complete, from Yonghong.

2) Fix sock_map_alloc()'s error path in order to correctly propagate
   the -EINVAL error in case of too large allocation requests. This
   was just recently introduced when fixing close hooks via ULP layer,
   fix from Eric.

3) Do not use GFP_ATOMIC in __cpu_map_entry_alloc(). Reason is that this
   will not work with the recent __ptr_ring_init_queue_alloc() conversion
   to kvmalloc_array(), where in case of fallback to vmalloc() that GFP
   flag is invalid, from Jason.

4) Fix two recent syzkaller warnings: i) fix bpf_prog_array_copy_to_user()
   when a prog query with a big number of ids was performed where we'd
   otherwise trigger a warning from allocator side, ii) fix a missing
   mlock precharge on arraymaps, from Daniel.

5) Two fixes for bpftool in order to avoid breaking JSON output when used
   in batch mode, from Quentin.

6) Move a pr_debug() in libbpf in order to avoid having an otherwise
   uninitialized variable in bpf_program__reloc_text(), from Jeremy.
