Fix 32-bit overflow in value pointer calculations in BPF array map. And then
raise obsolete limit on array map value size. Add selftest making sure this is
working as intended.
v1->v2:
- fix broken patch #1 (no mask_index use in helper, as stated in commit
message; and add missing semicolon).
Andrii Nakryiko (4):
bpf: fix potential 32-bit overflow when accessing ARRAY map element
bpf: make uniform use of array->elem_size everywhere in arraymap.c
bpf: remove obsolete KMALLOC_MAX_SIZE restriction on array map value
size
selftests/bpf: validate .bss section bigger than 8MB is possible now
