2022-02-16selftests/bpf: Test "bpftool gen min_core_btf"Mauricio Vásquez
This commit reuses the core_reloc test to check if the BTF files generated with "bpftool gen min_core_btf" are correct. This introduces test_core_btfgen() that runs all the core_reloc tests, but this time the source BTF files are generated by using "bpftool gen min_core_btf". The goal of this test is to check that the generated files are usable, and not to check if the algorithm is creating an optimized BTF file.

2022-02-16lkdtm: Add a test for function descriptors protectionChristophe Leroy
Add WRITE_OPD to check that you can't modify function descriptors. Gives the following result when function descriptors are not protected: lkdtm: Performing direct entry WRITE_OPD lkdtm: attempting bad 16 bytes write at c00000000269b358 lkdtm: FAIL: survived bad write lkdtm: do_nothing was hijacked! Looks like a standard compiler barrier() is not enough to force GCC to use the modified function descriptor. Had to add a fake empty inline assembly to force GCC to reload the function descriptor.

bpf_msg_push_data may return a non-zero value to indicate an error. The return value should be checked to prevent undetected errors. To indicate an error, the BPF programs now perform a different action than their intended one to make the userspace test program notice the error, i.e., the programs supposed to pass/redirect drop, the program supposed to drop passes.

2022-02-15selftests/bpf: Fix GCC11 compiler warnings in -O2 modeAndrii Nakryiko
When compiling selftests in -O2 mode with GCC1, we get three new compilations warnings about potentially uninitialized variables. Compiler is wrong 2 out of 3 times, but this patch makes GCC11 happy anyways, as it doesn't cost us anything and makes optimized selftests build less annoying. The amazing one is tc_redirect case of token that is malloc()'ed before ASSERT_OK_PTR() check is done on it. Seems like GCC pessimistically assumes that libbpf_get_error() will dereference the contents of the pointer (no it won't), so the only way I found to shut GCC up was to do zero-initializaing calloc(). This one was new to me. For linfo case, GCC didn't realize that linfo_size will be initialized by the function that is returning linfo_size as out parameter. core_reloc.c case was a real bug, we can goto cleanup before initializing obj. But we don't need to do any clean up, so just continue iteration intstead.

2022-02-15kselftest/arm64: mte: user_mem: test a wider range of valuesJoey Gouly
Instead of hard coding a small amount of tests, generate a wider range of tests to try catch any corner cases that could show up. These new tests test different MTE tag lengths and offsets, which previously would have caused infinite loops in the kernel. This was fixed by 295cf156231c ("arm64: Avoid premature usercopy failure"), so these are regressions tests for that corner case.

These can be used to place an MTE tag at an address that is not at a page size boundary. The kernel prior to 295cf156231c ("arm64: Avoid premature usercopy failure"), would infinite loop if an MTE tag was placed not at a PAGE_SIZE boundary. This is because the kernel checked if the pages were readable by checking the first byte of each page, but would then fault in the middle of the page due to the MTE tag.

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.

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: 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.

2022-02-11ipv6: Reject routes configurations that specify dsfield (tos)Guillaume Nault
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.

Some distros may enable rp_filter by default. After ns1 change addr to 10.0.2.99 and set default router to 10.0.2.1, while the connected router address is still 10.0.1.1. The router will not reply the arp request from ns1. Fix it by setting the router's veth0 rp_filter to 0.

2022-02-10KVM: selftests: nSVM: Add enlightened MSR-Bitmap selftestVitaly Kuznetsov
Introduce a new test for Hyper-V nSVM extensions (Hyper-V on KVM) and add a test for enlightened MSR-Bitmap feature: - Intercept access to MSR_FS_BASE in L1 and check that this works with enlightened MSR-Bitmap disabled. - Enabled enlightened MSR-Bitmap and check that the intercept still works as expected. - Intercept access to MSR_GS_BASE but don't clear the corresponding bit from clean fields mask, KVM is supposed to skip updating MSR-Bitmap02 and thus the consequent access to the MSR from L2 will not get intercepted. - Finally, clear the corresponding bit from clean fields mask and check that access to MSR_GS_BASE is now intercepted. The test works with the assumption, that access to MSR_FS_BASE/MSR_GS_BASE is not intercepted for L1. If this ever becomes not true the test will fail as nested_svm_exit_handled_msr() always checks L1's MSR-Bitmap for L2 irrespective of clean fields. The behavior is correct as enlightened MSR-Bitmap feature is just an optimization, KVM is not obliged to ignore updates when the corresponding bit in clean fields stays clear.
