Hi guys,

is there any tool which displays and find all symbols and what symbol hierarchy must be enabled to display the one hidden?

I of course followed this:
https://cateee.net/lkddb/web-lkddb/IPVLAN.html

And all configs required are enabled.... but still I cannot see in my .config file anything like CONFIG_IPVLAN...

I struggled this back in time, but having stable minimalistic kernels for all my hardware done (servers, laptops, workstation)... but now again, while trying to run docker on kernel-4.9.76-r1 (gentoo-sources) I cannot find and enable CONFIG_IPVLAN symbol.

Is there any tool to help me find the symbol via make make xconfig/menuconfig, etc.?

Thank you for any hint.

archenroot,

In kernel-4.17.2, it says
Code:
  │ Symbol: IPVLAN [=n]                                                                                           │ 
  │ Type  : tristate                                                                                              │ 
  │ Prompt: IP-VLAN support                                                                                       │ 
  │   Location:                                                                                                   │ 
  │     -> Device Drivers                                                                                         │ 
  │       -> Network device support (NETDEVICES [=y])                                                             │ 
  │ (1)     -> Network core driver support (NET_CORE [=y])                                                        │ 
  │   Defined at drivers/net/Kconfig:149                                                                          │ 
  │   Depends on: NETDEVICES [=y] && NET_CORE [=y] && INET [=y] && (IPV6 [=y] || !IPV6 [=y]) && NETFILTER [=y]    │ 
  │   Selects: NET_L3_MASTER_DEV [=n]


The search can find it, even if its hidden. Press 'z' to show all symbols. That's a toggle.
Search normally.
You can go to the option and read its help but if its marked
Code:
- -
its not selectable.

Thank you for checking on later kernel, maybe I will upgrade anyway and going to test your way.

I tried in xconfig, but without luck, the search didn't show me it, although someone elsewhere said xconfig can show even hidden symbols.

archenroot,

All the config tools except
Code:
make config
can show hidden symbols.
