[PATCH v2 4/5] selftests/sgx: Include the dynamic heap size to the ELRANGE calculation

by Jarkko Sakkinen

When calculating ELRANGE, i.e. the address range defined for an enclave, and represented by encl->encl_size, also dynamic memory should be taken into account. Implement setup_test_encl_dynamic() with dynamic_size parameter for the dynamic heap size, and use it in 'augment_via_eaccept' and 'augment' tests.

[PATCH v2 3/5] selftests/sgx: Use encl->encl_size in sigstruct.c

by Jarkko Sakkinen

The final enclave address range (referred as ELRANGE in Intel SDM) calculation is a reminiscent of signing tool being a separate command-line utility, and sigstruct being produced during the compilation. Given that nowadays the sigstruct is calculated on-fly, use the readily calculated encl->encl_size instead, in order to remove duplicate code.

[PATCH 0/7] bpf: Add fd modes check for map iter and extend libbpf

by Roberto Sassu

From: Roberto Sassu <roberto.sassu(a)huawei.com> Add a missing fd modes check in map iterators, potentially causing unauthorized map writes by eBPF programs attached to the iterator. Use this patch set as an opportunity to start a discussion with the cgroup developers about whether a security check is missing or not for their iterator. Also, extend libbpf with the _opts variant of bpf_*_get_fd_by_id(). Only bpf_map_get_fd_by_id_opts() is really useful in this patch set, to ensure that the creation of a map iterator fails with a read-only fd. Add all variants in this patch set for symmetry with bpf_map_get_fd_by_id_opts(), and because all the variants share the same opts structure. Also, add all the variants here, to shrink the patch set fixing map permissions requested by bpftool, so that the remaining patches are only about the latter. Finally, extend the bpf_iter test with the read-only fd check, and test each _opts variant of bpf_*_get_fd_by_id(). Roberto Sassu (7): bpf: Add missing fd modes check for map iterators libbpf: Define bpf_get_fd_opts and introduce bpf_map_get_fd_by_id_opts() libbpf: Introduce bpf_prog_get_fd_by_id_opts() libbpf: Introduce bpf_btf_get_fd_by_id_opts() libbpf: Introduce bpf_link_get_fd_by_id_opts() selftests/bpf: Ensure fd modes are checked for map iters and destroy links selftests/bpf: Add tests for _opts variants of libbpf include/linux/bpf.h | 2 +- kernel/bpf/inode.c | 2 +- kernel/bpf/map_iter.c | 3 +- kernel/bpf/syscall.c | 8 +- net/core/bpf_sk_storage.c | 3 +- net/core/sock_map.c | 3 +- tools/lib/bpf/bpf.c | 47 +++++- tools/lib/bpf/bpf.h | 16 ++ tools/lib/bpf/libbpf.map | 10 +- tools/lib/bpf/libbpf_version.h | 2 +- .../selftests/bpf/prog_tests/bpf_iter.c | 34 +++- .../bpf/prog_tests/libbpf_get_fd_opts.c | 145 ++++++++++++++++++ .../bpf/progs/test_libbpf_get_fd_opts.c | 49 ++++++ 13 files changed, 309 insertions(+), 15 deletions(-) create mode 100644 tools/testing/selftests/bpf/prog_tests/libbpf_get_fd_opts.c create mode 100644 tools/testing/selftests/bpf/progs/test_libbpf_get_fd_opts.c -- 2.25.1
