bpf: add various verifier test cases

2017-05-25T17:44:28+00:00

This patch adds various verifier test cases:

1) A test case for the pruning issue when tracking alignment
   is used.
2) Various PTR_TO_MAP_VALUE_OR_NULL tests to make sure pointer
   arithmetic turns such register into UNKNOWN_VALUE type.
3) Test cases for the special treatment of LD_ABS/LD_IND to
   make sure verifier doesn't break calling convention here.
   Latter is needed, since f.e. arm64 JIT uses r1 - r5 for
   storing temporary data, so they really must be marked as
   NOT_INIT.

tools lib string: Adopt prefixcmp() from perf and subcmd

2017-04-26T18:49:21+00:00

Both had copies originating from git.git, move those to
tools/lib/string.c, getting both tools/lib/subcmd/ and tools/perf/ to
use it.

tools include: Drop ARRAY_SIZE() definition from linux/hashtable.h

2017-04-19T16:01:45+00:00

As tools/include/linux/kernel.h has it now, with the goodies present in
the kernel.h counterpart, i.e. checking that the parameter is an array
at build time.

tools include: Move ARRAY_SIZE() to linux/kernel.h

2017-04-19T16:01:43+00:00

To match the kernel, then look for places redefining it to make it use
this version, which checks that its parameter is an array at build time.

tools include: Adopt __same_type() and __must_be_array() from the kernel

2017-04-19T16:01:42+00:00

Will be used to adopt the more stringent version of ARRAY_SIZE(), the
one in the kernel sources.

With just what we will need in the upcoming changesets, the
BUILD_BUG_ON_ZERO() definition.

bpf: add various verifier test cases for self-tests

2017-04-01T19:36:37+00:00

Add a couple of test cases, for example, probing for xadd on a spilled
pointer to packet and map_value_adj register, various other map_value_adj
tests including the unaligned load/store, and trying out pointer arithmetic
on map_value_adj register itself. For the unaligned load/store, we need
to figure out whether the architecture has efficient unaligned access and
need to mark affected tests accordingly.
