2023-06-08tools: ynl-gen: use enum names in op strmap more carefullyJakub Kicinski
In preparation for supporting families which use different msg ids to and from the kernel - make sure the ids in op strmap are correct. The map is expected to be used mostly for notifications, don't generate a separate map for the "to kernel" direction. Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2023-06-07tools: ynl-gen: improve unwind on parsing errorsJakub Kicinski
When parsing multi-attr we count the objects and then allocate an array to hold the parsed objects. If an attr space has multiple multi-attr objects, however, if parsing the first array fails we'll leave the object count for the second even tho the second array was never allocated. This may cause crashes when freeing objects on error. Count attributes to a variable on the stack and only set the count in the object once the memory was allocated.

2023-06-05bpf: netfilter: Add BPF_NETFILTER bpf_attach_typeFlorian Westphal
Andrii Nakryiko writes: And we currently don't have an attach type for NETLINK BPF link. Thankfully it's not too late to add it. I see that link_create() in kernel/bpf/syscall.c just bypasses attach_type check. We shouldn't have done that. Instead we need to add BPF_NETLINK attach type to enum bpf_attach_type. And wire all that properly throughout the kernel and libbpf itself. This adds BPF_NETFILTER and uses it. This breaks uabi but this wasn't in any non-rc release yet, so it should be fine. v2: check link_attack prog type in link_create too Fixes: 84601d6ee68a ("bpf: add bpf_link support for BPF_NETFILTER programs") Suggested-by: Andrii Nakryiko <andrii.nakryiko@gmail.com> Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Link: https://lore.kernel.org/bpf/CAEf4BzZ69YgrQW7DHCJUT_X+GqMq_ZQQPBwopaJJVGFD5=d5Vg@mail.gmail.com/ Link: https://lore.kernel.org/bpf/20230605131445.32016-1-fw@strlen.de

This configuration seems too close to "works by accident", and it would be better to just shut out VLAN 1 altogether.

Selftests are supposed to run on any kernels, including the old ones not supporting MPTCP. A new check is then added to make sure MPTCP is supported. If not, the test stops and is marked as "skipped". Note that this check can also mark the test as failed if 'SELFTESTS_MPTCP_LIB_EXPECT_ALL_FEATURES' env var is set to 1: by doing that, we can make sure a test is not being skipped by mistake. A new shared file is added here to be able to re-used the same check in the different selftests we have.

2023-05-30selftests: mptcp: join: avoid using 'cmp --bytes'Matthieu Baerts
BusyBox's 'cmp' command doesn't support the '--bytes' parameter. Some CIs -- i.e. LKFT -- use BusyBox and have the mptcp_join.sh test failing [1] because their 'cmp' command doesn't support this '--bytes' option: cmp: unrecognized option '--bytes=1024' BusyBox v1.35.0 () multi-call binary. Usage: cmp [-ls] [-n NUM] FILE1 [FILE2] Instead, 'head --bytes' can be used as this option is supported by BusyBox. A temporary file is needed for this operation. Because it is apparently quite common to use BusyBox, it is certainly better to backport this fix to impacted kernels.
