[PATCH net v2 0/3] Couple of BPF fixes

[Daniel Borkmann <daniel@iogearbox.net>]

This set contains three BPF fixes for net, one that addresses the
complaint from Geert wrt static allocations, and the other is a fix
wrt mem accounting that I found recently during testing and there's
still one more fix on the map value marking.

Thanks!

v1 -> v2:
  - Patch 1 as is.
  - Fixed kbuild bot issue by letting charging helpers stay in the
    syscall.c, since there locked_vm is valid and only export the
    ones needed by bpf_prog_realloc(). Add empty stubs in case the
    bpf syscall is not enabled.
  - Added patch 3 that addresses one more issue in map val marking.

Daniel Borkmann (3):
  bpf: dynamically allocate digest scratch buffer
  bpf: fix overflow in prog accounting
  bpf: fix mark_reg_unknown_value for spilled regs on map value marking
