bpf: Clarify handling of mark and tstamp by redirect_peer

2025-05-08T01:16:33Z

When switching network namespaces with the bpf_redirect_peer helper, the skb->mark and skb->tstamp fields are not zeroed out like they can be on a typical netns switch. This patch clarifies that in the helper description.

tools/include: make uapi/linux/types.h usable from assembly

2025-04-06T19:55:31Z

The "real" linux/types.h UAPI header gracefully degrades to a NOOP when included from assembly code. Mirror this behaviour in the tools/ variant. Test for __ASSEMBLER__ over __ASSEMBLY__ as the former is provided by the toolchain automatically.
