[LTP] [PATCH v2 0/5] BPF refactor and add bpf_prog05

[Richard Palethorpe]

Hello,

V2:

* Added a number of helper functions to bpf_common and used them on
  all tests.

* Added some instruction concatenation helpers, but only used these on
  bpf_prog05 as they don't seem to make the other tests better to
  read.

* Further shorten bpf_prog05 by using a generic expect function

Richard Palethorpe (5):
  lapi/bpf: Add /=, %= and BPF_MAXINSNS
  bpf: Add map_array helper functions
  bpf: Add helper to run socket programs
  bpf: Add bpf_insn_buf, map and instruction concatenation helpers
  bpf: Check truncation on 32bit div/mod by zero
