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.

selftests/bpf: fix broken build, take 2

2017-03-22T01:57:58+00:00

Merge of 'linux-kselftest-4.11-rc1':

1. Partially removed use of 'test_objs' target, breaking force rebuild of
BPFOBJ, introduced in commit d498f8719a09 ("bpf: Rebuild bpf.o for any
dependency update").

  Update target so dependency on BPFOBJ is restored.

2. Introduced commit 2047f1d8ba28 ("selftests: Fix the .c linking rule")
which fixes order of LDLIBS.

  Commit d02d8986a768 ("bpf: Always test unprivileged programs") added
libcap dependency into CFLAGS. Use LDLIBS instead to fix linking of
test_verifier.

3. Introduced commit d83c3ba0b926 ("selftests: Fix selftests build to
just build, not run tests").

  Reordering the Makefile allows us to remove the 'all' target.

Tested both:
    selftests/bpf$ make
and
    selftests$ make TARGETS=bpf
on Ubuntu 16.04.2.

selftests/bpf: fix broken build

2017-03-13T06:48:41+00:00

Recent merge of 'linux-kselftest-4.11-rc1' tree broke bpf test build.
None of the tests were building and test_verifier.c had tons of compiler errors.
Fix it and add #ifdef CAP_IS_SUPPORTED to support old versions of libcap.
Tested on centos 6.8 and 7

bpf: Rebuild bpf.o for any dependency update

2017-02-15T17:16:17+00:00

This is needed to force a rebuild of bpf.o when one of its dependencies
(e.g. uapi/linux/bpf.h) is updated.

Add a phony target.

bpf: Always test unprivileged programs

2017-02-10T20:56:06+00:00

If selftests are run as root, then execute the unprivileged checks as
well. This switch from 243 to 368 tests.

The test numbers are suffixed with "/u" when executed as unprivileged or
with "/p" when executed as privileged.

The geteuid() check is replaced with a capability check.

Handling capabilities requires the libcap dependency.

bpf: Add tests for the lpm trie map

2017-01-23T21:10:38+00:00

The first part of this program runs randomized tests against the
lpm-bpf-map. It implements a "Trivial Longest Prefix Match" (tlpm)
based on simple, linear, single linked lists. The implementation
should be pretty straightforward.

Based on tlpm, this inserts randomized data into bpf-lpm-maps and
verifies the trie-based bpf-map implementation behaves the same way
as tlpm.

The second part uses 'real world' IPv4 and IPv6 addresses and tests
the trie with those.
