CONFIG_IP6_NF_TARGET_HL: 'HL' hoplimit target support

General informations

The Linux kernel configuration item CONFIG_IP6_NF_TARGET_HL has multiple definitions:

'HL' hoplimit target support found in net/ipv6/netfilter/Kconfig

The configuration item CONFIG_IP6_NF_TARGET_HL:

• prompt: 'HL' hoplimit target support
• type: tristate
• depends on: CONFIG_NETFILTER_ADVANCED && CONFIG_IP6_NF_MANGLE
• defined in net/ipv6/netfilter/Kconfig
• found in Linux kernels: 2.6.30–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.12, 6.13-rc+HEAD
• modules built: ip6t_HL

Help text

This is a backwards-compatible option for the user's convenience (e.g. when running oldconfig). It selects NETFILTER_XT_TARGET_HL.

HL (hoplimit) target support found in net/ipv6/netfilter/Kconfig

The configuration item CONFIG_IP6_NF_TARGET_HL:

• prompt: HL (hoplimit) target support
• type: tristate
• depends on: ( CONFIG_IP6_NF_MANGLE ) && ( CONFIG_NETFILTER_ADVANCED )
• defined in net/ipv6/netfilter/Kconfig
• found in Linux kernels: 2.6.14–2.6.29
• modules built: ip6t_HL

Help text

This option adds a `HL' target, which enables the user to decrement the hoplimit value of the IPv6 header or set it to a given (lower) value.

While it is safe to decrement the hoplimit value, this option also enables functionality to increment and set the hoplimit value of the IPv6 header to arbitrary values. This is EXTREMELY DANGEROUS since you can easily create immortal packets that loop forever on the network.

To compile it as a module, choose M here. If unsure, say N.
