2022-02-14selftests/seccomp: Fix seccomp failure by adding missing headersSherry Yang
seccomp_bpf failed on tests 47 global.user_notification_filter_empty and 48 global.user_notification_filter_empty_threaded when it's tested on updated kernel but with old kernel headers. Because old kernel headers don't have definition of macro __NR_clone3 which is required for these two tests. Since under selftests/, we can install headers once for all tests (the default INSTALL_HDR_PATH is usr/include), fix it by adding usr/include to the list of directories to be searched. Use "-isystem" to indicate it's a system directory as the real kernel headers directories are.

2022-02-14net/sched: act_police: more accurate MTU policingDavide Caratti
in current Linux, MTU policing does not take into account that packets at the TC ingress have the L2 header pulled. Thus, the same TC police action (with the same value of tcfp_mtu) behaves differently for ingress/egress. In addition, the full GSO size is compared to tcfp_mtu: as a consequence, the policer drops GSO packets even when individual segments have the L2 + L3 + L4 + payload length below the configured valued of tcfp_mtu. Improve the accuracy of MTU policing as follows: - account for mac_len for non-GSO packets at TC ingress. - compare MTU threshold with the segmented size for GSO packets. Also, add a kselftest that verifies the correct behavior. Signed-off-by: Davide Caratti <dcaratti@redhat.com> Reviewed-by: Marcelo Ricardo Leitner <marcelo.leitner@gmail.com> Signed-off-by: David S.

2022-02-11selftests/sgx: Remove extra newlines in test outputReinette Chatre
The TH_LOG() macro is an optional debug logging function made available by kselftest itself. When TH_LOG_ENABLED is set it prints the provided message with additional information and formatting that already includes a newline. Providing a newline to the message printed by TH_LOG() results in a double newline that produces irregular test output. Remove the unnecessary newlines from the text provided to TH_LOG().

2022-02-11selftests/sgx: Fix NULL-pointer-dereference upon early test failureReinette Chatre
== Background == The SGX selftests track parts of the enclave binaries in an array: encl->segment_tbl[]. That array is dynamically allocated early (but not first) in the test's lifetime. The array is referenced at the end of the test in encl_delete(). == Problem == encl->segment_tbl[] can be NULL if the test fails before its allocation. That leads to a NULL-pointer-dereference in encl_delete(). This is triggered during early failures of the selftest like if the enclave binary ("test_encl.elf") is deleted. == Solution == Ensure encl->segment_tbl[] is valid before attempting to access its members. The offset with which it is accessed, encl->nr_segments, is initialized before encl->segment_tbl[] and thus considered valid to use after the encl->segment_tbl[] check succeeds.

The ->rtm_tos option is normally used to route packets based on both the destination address and the DS field. However it's ignored for IPv6 routes. Setting ->rtm_tos for IPv6 is thus invalid as the route is going to work only on the destination address anyway, so it won't behave as specified.

2022-02-09selftests: mptcp: add missing join checkMatthieu Baerts
This function also writes the name of the test with its ID, making clear a new test has been executed. Without that, the ADD_ADDR results from this test was appended at the end of the previous test causing confusions. Especially when the second test was failing, we had: 17 signal invalid addresses syn[ ok ] - synack[ ok ] - ack[ ok ] add[ ok ] - echo [ ok ] add[fail] got 2 ADD_ADDR[s] expected 3 In fact, this 17th test was OK but not the 18th one. Now we have: 17 signal invalid addresses syn[ ok ] - synack[ ok ] - ack[ ok ] add[ ok ] - echo [ ok ] 18 signal addresses race test syn[fail] got 2 JOIN[s] syn expected 3 - synack[fail] got 2 JOIN[s] synack expected - ack[fail] got 2 JOIN[s] ack expected 3 add[fail] got 2 ADD_ADDR[s] expected 3 Fixes: 33c563ad28e3 ("selftests: mptcp: add_addr and echo race test") Reported-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: Matthieu Baerts <matthieu.baerts@tessares.net> Signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

The main changes are: 1) Add custom BPF allocator for JITs that pack multiple programs into a huge page to reduce iTLB pressure, from Song Liu. 2) Add __user tagging support in vmlinux BTF and utilize it from BPF verifier when generating loads, from Yonghong Song. 3) Add per-socket fast path check guarding from cgroup/BPF overhead when used by only some sockets, from Pavel Begunkov. 4) Continued libbpf deprecation work of APIs/features and removal of their usage from samples, selftests, libbpf & bpftool, from Andrii Nakryiko and various others. 5) Improve BPF instruction set documentation by adding byte swap instructions and cleaning up load/store section, from Christoph Hellwig. 6) Switch BPF preload infra to light skeleton and remove libbpf dependency from it, from Alexei Starovoitov. 7) Fix architecture-agnostic macros in libbpf for accessing syscall arguments from BPF progs for non-x86 architectures, from Ilya Leoshkevich. 8) Rework port members in struct bpf_sk_lookup and struct bpf_sock to be of 16-bit field with anonymous zero padding, from Jakub Sitnicki. 9) Add new bpf_copy_from_user_task() helper to read memory from a different task than current. Add ability to create sleepable BPF iterator progs, from Kenny Yu. 10) Implement XSK batching for ice's zero-copy driver used by AF_XDP and utilize TX batching API from XSK buffer pool, from Maciej Fijalkowski. 11) Generate temporary netns names for BPF selftests to avoid naming collisions, from Hangbin Liu. 12) Implement bpf_core_types_are_compat() with limited recursion for in-kernel usage, from Matteo Croce. 13) Simplify pahole version detection and finally enable CONFIG_DEBUG_INFO_DWARF5 to be selected with CONFIG_DEBUG_INFO_BTF, from Nathan Chancellor. 14) Misc minor fixes to libbpf and selftests from various folks. * https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (126 commits) selftests/bpf: Cover 4-byte load from remote_port in bpf_sk_lookup bpf: Make remote_port field in struct bpf_sk_lookup 16-bit wide libbpf: Fix compilation warning due to mismatched printf format selftests/bpf: Test BPF_KPROBE_SYSCALL macro libbpf: Add BPF_KPROBE_SYSCALL macro libbpf: Fix accessing the first syscall argument on s390 libbpf: Fix accessing the first syscall argument on arm64 libbpf: Allow overriding PT_REGS_PARM1{_CORE}_SYSCALL selftests/bpf: Skip test_bpf_syscall_macro's syscall_arg1 on arm64 and s390 libbpf: Fix accessing syscall arguments on riscv libbpf: Fix riscv register names libbpf: Fix accessing syscall arguments on powerpc selftests/bpf: Use PT_REGS_SYSCALL_REGS in bpf_syscall_macro libbpf: Add PT_REGS_SYSCALL_REGS macro selftests/bpf: Fix an endianness issue in bpf_syscall_macro test bpf: Fix bpf_prog_pack build HPAGE_PMD_SIZE bpf: Fix leftover header->pages in sparc and powerpc code. libbpf: Fix signedness bug in btf_dump_array_data() selftests/bpf: Do not export subtest as standalone test bpf, x86_64: Fail gracefully on bpf_jit_binary_pack_finalize failures ... ==================== Link: https://lore.kernel.org/r/20220209210050.8425-1-daniel@iogearbox.net Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2022-02-09selftests: netfilter: fix exit value for nft_concat_rangeHangbin Liu
When the nft_concat_range test failed, it exit 1 in the code specifically. But when part of, or all of the test passed, it will failed the [ ${passed} -eq 0 ] check and thus exit with 1, which is the same exit value with failure result. Fix it by exit 0 when passed is not 0.
