ENUM NFT_TRACE_ATTRIBUTES(9)

💖 NAME 💖

okay bestie, welcome to the enum nft_trace_attributes(9) page from the Kernel API Manual 💅 this is literally the nf_tables trace netlink attributes enum — the guest list of netlink attrs that show up when tracing nf_tables. no cap, it's giving “packet receipts” energy. ✨

✨ SYNOPSIS ✨

the enum is literally:

enum nft_trace_attributes {
    NFTA_TRACE_UNSPEC ,
    NFTA_TRACE_TABLE ,
    NFTA_TRACE_CHAIN ,
    NFTA_TRACE_RULE_HANDLE ,
    NFTA_TRACE_TYPE ,
    NFTA_TRACE_VERDICT ,
    NFTA_TRACE_ID ,
    NFTA_TRACE_LL_HEADER ,
    NFTA_TRACE_NETWORK_HEADER ,
    NFTA_TRACE_TRANSPORT_HEADER ,
    NFTA_TRACE_IIF ,
    NFTA_TRACE_IIFTYPE ,
    NFTA_TRACE_OIF ,
    NFTA_TRACE_OIFTYPE ,
    NFTA_TRACE_MARK ,
    NFTA_TRACE_NFPROTO ,
    NFTA_TRACE_POLICY ,
    NFTA_TRACE_PAD ,
    NFTA_TRACE_CT_ID ,
    NFTA_TRACE_CT_DIRECTION ,
    NFTA_TRACE_CT_STATUS ,
    NFTA_TRACE_CT_STATE ,
    __NFTA_TRACE_MAX

};

🎀 Constants 🎀

every single one, same order, no skips — this is the whole squad:

• NFTA_TRACE_UNSPEC — -- undescribed -- (the manpage really just says that, bestie 🙈)
• NFTA_TRACE_TABLE — name of the table (NLA_STRING) 🪄
• NFTA_TRACE_CHAIN — name of the chain (NLA_STRING) 🔗
• NFTA_TRACE_RULE_HANDLE — numeric handle of the rule (NLA_U64) 🔢
• NFTA_TRACE_TYPE — type of the event (NLA_U32: nft_trace_types) 🌟
• NFTA_TRACE_VERDICT — verdict returned by hook (NLA_NESTED: nft_verdicts) ⚖️
• NFTA_TRACE_ID — pseudo-id, same for each skb traced (NLA_U32) 🆔
• NFTA_TRACE_LL_HEADER — linklayer header (NLA_BINARY) 🧱
• NFTA_TRACE_NETWORK_HEADER — network header (NLA_BINARY) 🌐
• NFTA_TRACE_TRANSPORT_HEADER — transport header (NLA_BINARY) 🚚
• NFTA_TRACE_IIF — indev ifindex (NLA_U32) 📥
• NFTA_TRACE_IIFTYPE — netdev->type of indev (NLA_U16) 🏷️
• NFTA_TRACE_OIF — outdev ifindex (NLA_U32) 📤
• NFTA_TRACE_OIFTYPE — netdev->type of outdev (NLA_U16) 🏷️
• NFTA_TRACE_MARK — nfmark (NLA_U32) 🖍️
• NFTA_TRACE_NFPROTO — nf protocol processed (NLA_U32) 📡
• NFTA_TRACE_POLICY — policy that decided fate of packet (NLA_U32) 👑
• NFTA_TRACE_PAD — -- undescribed -- (again, no tea from the manpage 🙈)
• NFTA_TRACE_CT_ID — conntrack id (NLA_U32) 🧾
• NFTA_TRACE_CT_DIRECTION — packets direction (NLA_U8) 🧭
• NFTA_TRACE_CT_STATUS — conntrack status (NLA_U32) 📊
• NFTA_TRACE_CT_STATE — packet state (new, established, ...) (NLA_U32) 🫧
• __NFTA_TRACE_MAX — -- undescribed -- (the final boss and still undescribed 😭)

bestie, when it says -- undescribed --, that’s the manpage being shy — no invented lore from me, fr fr 🫶
