2023-03-29libbpf: disassociate section handler on explicit bpf_program__set_type() callAndrii Nakryiko
If user explicitly overrides programs's type with bpf_program__set_type() API call, we need to disassociate whatever SEC_DEF handler libbpf determined initially based on program's SEC() definition, as it's not goind to be valid anymore and could lead to crashes and/or confusing failures. Also, fix up bpf_prog_test_load() helper in selftests/bpf, which is force-setting program type (even if that's completely unnecessary; this is quite a legacy piece of code), and thus should expect auto-attach to not work, yet one of the tests explicitly relies on auto-attach for testing. Instead, force-set program type only if it differs from the desired one.

2023-03-29macvlan: Add netlink attribute for broadcast cutoffHerbert Xu
Make the broadcast cutoff configurable through netlink. Note that macvlan is weird because there is no central device for us to configure (the lowerdev could be anything). So all the options are duplicated over what could be thousands of child devices. IFLA_MACVLAN_BC_QUEUE_LEN took the approach of taking the maximum of all child device settings. This is unnecessary as we could simply store the option in the port device and take the last child device that gets updated as the value to use.

2023-03-27libbpf: Fix double-free when linker processes empty sectionsEduard Zingerman
Double-free error in bpf_linker__free() was reported by James Hilliard. The error is caused by miss-use of realloc() in extend_sec(). The error occurs when two files with empty sections of the same name are linked: - when first file is processed: - extend_sec() calls realloc(dst->raw_data, dst_align_sz) with dst->raw_data == NULL and dst_align_sz == 0; - dst->raw_data is set to a special pointer to a memory block of size zero; - when second file is processed: - extend_sec() calls realloc(dst->raw_data, dst_align_sz) with dst->raw_data == <special pointer> and dst_align_sz == 0; - realloc() "frees" dst->raw_data special pointer and returns NULL; - extend_sec() exits with -ENOMEM, and the old dst->raw_data value is preserved (it is now invalid); - eventually, bpf_linker__free() attempts to free dst->raw_data again. This patch fixes the bug by avoiding -ENOMEM exit for dst_align_sz == 0. The fix was suggested by Andrii Nakryiko <andrii.nakryiko@gmail.com>.

I was a bit too optimistic in commit bf51d27704c9 ("tools: ynl: fix get_mask utility routine"), not every mask we use is necessarily coming from an enum of type "flags".
