2022-02-17selftests/sgx: Treat CC as one argumentMuhammad Usama Anjum1-1/+1
CC can have multiple sub-strings like "ccache gcc". For check_cc.sh, CC needs to be treated like one argument. Put double quotes around it to make CC one string and hence one argument.

Add check to test if CC has a string. CC can have multiple sub-strings like "ccache gcc". Erorr pops up if it is treated as single string and double quotes are used around it. This can be fixed by removing the quotes and not treating CC as a single string.

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.

bpf_msg_push_data may return a non-zero value to indicate an error. The return value should be checked to prevent undetected errors.

2022-02-15selftests/bpf: Fix GCC11 compiler warnings in -O2 modeAndrii Nakryiko3-3/+3
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.

These new tests test different MTE tag lengths and offsets, which previously would have caused infinite loops in the kernel.

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.

2022-02-14net/sched: act_police: more accurate MTU policingDavide Caratti1-0/+52
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 <[email protected]> Reviewed-by: Marcelo Ricardo Leitner <[email protected]> Signed-off-by: David S.

== 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 Nault1-0/+13
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.
