Hi David,
The following pull-request contains BPF updates for your *net-next* tree.

Bad timing. I did something stupid on vger.kernel.org, it ran out of
disk space while the postings were being processed,
Actually, does it make sense to implement a list_map that supports
both pop_head()
and pop_tail()? Maybe gate one of the pop operations with options?
I am asking because mixing stack with stack trace is still confusing
after this patch.

map_lookup_elem isn't supported by certain map types like:
- BPF_MAP_TYPE_PROG_ARRAY
- BPF_MAP_TYPE_STACK_TRACE
- BPF_MAP_TYPE_XSKMAP
- BPF_MAP_TYPE_SOCKMAP/BPF_MAP_TYPE_SOCKHASH
Let's add verfier tests to check whether verifier prevents
bpf_map_lookup_elem call on above programs from bpf program.
Since map lookup error can be ENOENT or EOPNOTSUPP, let's print
strerror() as error message in normal and JSON output.
This patch adds helper function print_entry_error() to print
entry from lookup error occurs
Example: Following example dumps a map which does not support lookup.
Output before:
do_dump() function in bpftool/map.c has deep indentations. In order
to reduce deep indent, let's move element printing code out of
do_dump() into dump_map_elem() function.

fixup_map1 -> fixup_map_hash_8b

The error value returned by map_lookup_elem doesn't differentiate
whether lookup was failed because of invalid key or lookup is not
supported.
Lets add handling for -EOPNOTSUPP return value of map_lookup_elem()

should return -EOPNOT
Currently when map a lookup fails, user space API can not make any
