2022-09-21selftests/bpf: add tests for bpf_ct_set_nat_info kfuncLorenzo Bianconi1-0/+1
Introduce self-tests for bpf_ct_set_nat_info kfunc used to set the source or destination nat addresses/ports. Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Link: https://lore.kernel.org/r/803e33294e247744d466943105879414344d3235.1663778601.git.lorenzo@kernel.org Signed-off-by: Alexei Starovoitov <ast@kernel.org>
2022-09-21selftests/bpf: Add test for bpf_verify_pkcs7_signature() kfuncRoberto Sassu1-0/+5
Perform several tests to ensure the correct implementation of the bpf_verify_pkcs7_signature() kfunc. Do the tests with data signed with a generated testing key (by using sign-file from scripts/) and with the tcp_bic.ko kernel module if it is found in the system. The test does not fail if tcp_bic.ko is not found. First, perform an unsuccessful signature verification without data. Second, perform a successful signature verification with the session keyring and a new one created for testing. Then, ensure that permission and validation checks are done properly on the keyring provided to bpf_verify_pkcs7_signature(), despite those checks were deferred at the time the keyring was retrieved with bpf_lookup_user_key(). The tests expect to encounter an error if the Search permission is removed from the keyring, or the keyring is expired. Finally, perform a successful and unsuccessful signature verification with the keyrings with pre-determined IDs (the last test fails because the key is not in the platform keyring). The test is currently in the deny list for s390x (JIT does not support calling kernel function).

2022-09-21selftests/bpf: Add verifier tests for bpf_lookup_*_key() and bpf_key_put()Roberto Sassu1-0/+1
Add verifier tests for bpf_lookup_*_key() and bpf_key_put(), to ensure that acquired key references stored in the bpf_key structure are released, that a non-NULL bpf_key pointer is passed to bpf_key_put(), and that key references are not leaked. Also, slightly modify test_verifier.c, to find the BTF ID of the attach point for the LSM program type (currently, it is done only for TRACING).

2022-07-27selftests/bpf: Sort configurationDaniel Müller1-50/+49
This change makes sure to sort the existing minimal kernel configuration containing options required for running BPF selftests alphabetically. Doing so will make it easier to diff it against other configurations, which in turn helps with maintaining disjunct config files that build on top of each other. It also helped identify the CONFIG_IPV6_GRE being set twice and removes one of the occurrences. Lastly, we change NET_CLS_BPF from 'm' to 'y'. Having this option as 'm' will cause failures of the btf_skc_cls_ingress selftest.

2022-05-20selftests/bpf: Add MPTCP test baseNicolas Rybowski1-0/+1
This patch adds a base for MPTCP specific tests. It is currently limited to the is_mptcp field in case of plain TCP connection because there is no easy way to get the subflow sk from a msk in userspace. This implies that we cannot lookup the sk_storage attached to the subflow sk in the sockops program. v4: - add copyright 2022 (Andrii) - use ASSERT_* instead of CHECK_FAIL (Andrii) - drop SEC("version") (Andrii) - use is_mptcp in tcp_sock, instead of bpf_tcp_sock (Martin & Andrii) v5: - Drop connect_to_mptcp_fd (Martin) - Use BPF test skeleton (Andrii) - Use ASSERT_EQ (Andrii) - Drop the 'msg' parameter of verify_sk Co-developed-by: Geliang Tang <geliang.tang@suse.com> Signed-off-by: Geliang Tang <geliang.tang@suse.com> Signed-off-by: Nicolas Rybowski <nicolas.rybowski@tessares.net> Signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Acked-by: Matthieu Baerts <matthieu.baerts@tessares.net> Link: https://lore.kernel.org/bpf/20220519233016.105670-4-mathew.j.martineau@linux.intel.com

2022-05-11selftests/bpf: Enable CONFIG_FPROBE for self testsDaniel Müller1-0/+1
Some of the BPF selftests are failing when running with a rather bare bones configuration based on tools/testing/selftests/bpf/config. Specifically, we see a bunch of failures due to errno 95: > test_attach_api:PASS:fentry_raw_skel_load 0 nsec > libbpf: prog 'test_kprobe_manual': failed to attach: Operation not supported > test_attach_api:FAIL:bpf_program__attach_kprobe_multi_opts unexpected error: -95 > 79 /6 kprobe_multi_test/attach_api_syms:FAIL The cause of these is that CONFIG_FPROBE is missing.

2022-01-18selftests/bpf: Add test for race in btf_try_get_moduleKumar Kartikeya Dwivedi1-0/+1
This adds a complete test case to ensure we never take references to modules not in MODULE_STATE_LIVE, which can lead to UAF, and it also ensures we never access btf->kfunc_set_tab in an inconsistent state. The test uses userfaultfd to artificially widen the race. When run on an unpatched kernel, it leads to the following splat: [root@(none) bpf]# ./test_progs -t bpf_mod_race/ksym [ 55.498171] BUG: unable to handle page fault for address: fffffbfff802548b [ 55.499206] #PF: supervisor read access in kernel mode [ 55.499855] #PF: error_code(0x0000) - not-present page [ 55.500555] PGD a4fa9067 P4D a4fa9067 PUD a4fa5067 PMD 1b44067 PTE 0 [ 55.501499] Oops: 0000 [#1] PREEMPT SMP KASAN NOPTI [ 55.502195] CPU: 0 PID: 83 Comm: kworker/0:2 Tainted: G OE 5.16.0-rc4+ #151 [ 55.503388] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS ArchLinux 1.15.0-1 04/01/2014 [ 55.504777] Workqueue: events bpf_prog_free_deferred [ 55.505563] RIP: 0010:kasan_check_range+0x184/0x1d0 [ 55.509140] RSP: 0018:ffff88800560fcf0 EFLAGS: 00010282 [ 55.509977] RAX: fffffbfff802548b RBX: fffffbfff802548c RCX: ffffffff9337b6ba [ 55.511096] RDX: fffffbfff802548c RSI: 0000000000000004 RDI: ffffffffc012a458 [ 55.512143] RBP: fffffbfff802548b R08: 0000000000000001 R09: ffffffffc012a45b [ 55.513228] R10: fffffbfff802548b R11: 0000000000000001 R12: ffff888001b5f598 [ 55.514332] R13: ffff888004f49ac8 R14: 0000000000000000 R15: ffff888092449400 [ 55.515418] FS: 0000000000000000(0000) GS:ffff888092400000(0000) knlGS:0000000000000000 [ 55.516705] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 55.517560] CR2: fffffbfff802548b CR3: 0000000007c10006 CR4: 0000000000770ef0 [ 55.518672] PKRU: 55555554 [ 55.519022] Call Trace: [ 55.519483] <TASK> [ 55.519884] module_put.part.0+0x2a/0x180 [ 55.520642] bpf_prog_free_deferred+0x129/0x2e0 [ 55.521478] process_one_work+0x4fa/0x9e0 [ 55.522122] ? pwq_dec_nr_in_flight+0x100/0x100 [ 55.522878] ? rwlock_bug.part.0+0x60/0x60 [ 55.523551] worker_thread+0x2eb/0x700 [ 55.524176] ? __kthread_parkme+0xd8/0xf0 [ 55.524853] ? process_one_work+0x9e0/0x9e0 [ 55.525544] kthread+0x23a/0x270 [ 55.526088] ? set_kthread_struct+0x80/0x80 [ 55.526798] ret_from_fork+0x1f/0x30 [ 55.527413] </TASK> [ 55.527813] Modules linked in: bpf_testmod(OE) [last unloaded: bpf_testmod] [ 55.530846] CR2: fffffbfff802548b [ 55.531341] ---[ end trace 1af41803c054ad6d ]--- [ 55.532136] RIP: 0010:kasan_check_range+0x184/0x1d0 [ 55.535887] RSP: 0018:ffff88800560fcf0 EFLAGS: 00010282 [ 55.536711] RAX: fffffbfff802548b RBX: fffffbfff802548c RCX: ffffffff9337b6ba [ 55.537821] RDX: fffffbfff802548c RSI: 0000000000000004 RDI: ffffffffc012a458 [ 55.538899] RBP: fffffbfff802548b R08: 0000000000000001 R09: ffffffffc012a45b [ 55.539928] R10: fffffbfff802548b R11: 0000000000000001 R12: ffff888001b5f598 [ 55.541021] R13: ffff888004f49ac8 R14: 0000000000000000 R15: ffff888092449400 [ 55.542108] FS: 0000000000000000(0000) GS:ffff888092400000(0000) knlGS:0000000000000000 [ 55.543260]CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 55.544136] CR2: fffffbfff802548b CR3: 0000000007c10006 CR4: 0000000000770ef0 [ 55.545317] PKRU: 55555554 [ 55.545671] note: kworker/0:2[83] exited with preempt_count 1 Signed-off-by: Kumar Kartikeya Dwivedi <memxor@gmail.com> Link: https://lore.kernel.org/r/20220114163953.1455836-11-memxor@gmail.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>

Add selftests for prog/map/prog+helper feature probing APIs. Prog and map selftests are designed in such a way that they will always test all the possible prog/map types, based on running kernel's vmlinux BTF enum definition. This way we'll always be sure that when adding new BPF program types or map types, libbpf will be always updated accordingly to be able to feature-detect them. BPF prog_helper selftest will have to be manually extended with interesting and important prog+helper combinations, it's easy, but can't be completely automated.

2020-11-26bpf: Add a selftest for bpf_ima_inode_hashKP Singh1-0/+4
The test does the following: - Mounts a loopback filesystem and appends the IMA policy to measure executions only on this file-system. Restricting the IMA policy to a particular filesystem prevents a system-wide IMA policy change. - Executes an executable copied to this loopback filesystem. - Calls the bpf_ima_inode_hash in the bprm_committed_creds hook and checks if the call succeeded and checks if a hash was calculated. The test shells out to the added ima_setup.sh script as the setup is better handled in a shell script and is more complicated to do in the test program or even shelling out individual commands from C. The list of required configs (i.e. IMA, SECURITYFS, IMA_{WRITE,READ}_POLICY) for running this test are also updated.

2018-09-14selftests/bpf: test bpf flow dissectionPetar Penkov1-0/+1
Adds a test that sends different types of packets over multiple tunnels and verifies that valid packets are dissected correctly. To do so, a tc-flower rule is added to drop packets on UDP src port 9, and packets are sent from ports 8, 9, and 10. Only the packets on port 9 should be dropped. Because tc-flower relies on the flow dissector to match flows, correct classification demonstrates correct dissection. Also add support logic to load the BPF program and to inject the test packets.

CONFIG_NET_SCHED wasn't enabled in arm64's defconfig only for x86. So bpf/test_tunnel.sh tests fails with: RTNETLINK answers: Operation not supported RTNETLINK answers: Operation not supported We have an error talking to the kernel, -1 Enable NET_SCHED and more tests pass.

2016-10-18bpf: add initial suite for selftestsDaniel Borkmann1-0/+5
Add a start of a test suite for kernel selftests. This moves test_verifier and test_maps over to tools/testing/selftests/bpf/ along with various code improvements and also adds a script for invoking test_bpf module. The test suite can simply be run via selftest framework, f.e.: # cd tools/testing/selftests/bpf/ # make # make run_tests Both test_verifier and test_maps were kind of misplaced in samples/bpf/ directory and we were looking into adding them to selftests for a while now, so it can be picked up by kbuild bot et al and hopefully also get more exposure and thus new test case additions.
