[PATCH net v2 0/9] net: Fix MODULE_DESCRIPTION() for net (p5)

[PATCH net v2 0/9] net: Fix MODULE_DESCRIPTION() for net (p5)

[Breno Leitao]

There are hundreds of network modules that misses MODULE_DESCRIPTION(),
causing a warning when compiling with W=1. Example:

	WARNING: modpost: missing MODULE_DESCRIPTION() in net/sched/em_cmp.o
	WARNING: modpost: missing MODULE_DESCRIPTION() in net/sched/em_nbyte.o
	WARNING: modpost: missing MODULE_DESCRIPTION() in net/sched/em_u32.o
	WARNING: modpost: missing MODULE_DESCRIPTION() in net/sched/em_meta.o
	WARNING: modpost: missing MODULE_DESCRIPTION() in net/sched/em_text.o
	WARNING: modpost: missing MODULE_DESCRIPTION() in net/sched/em_canid.o
	WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv4/ip_tunnel.o
	WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv4/ipip.o
	WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv4/ip_gre.o
	WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv4/udp_tunnel.o
	WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv4/ip_vti.o
	WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv4/ah4.o
	WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv4/esp4.o
	WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv4/xfrm4_tunnel.o
	WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv4/tunnel4.o
	WARNING: modpost: missing MODULE_DESCRIPTION() in net/xfrm/xfrm_algo.o
	WARNING: modpost: missing MODULE_DESCRIPTION() in net/xfrm/xfrm_user.o
	WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv6/ah6.o
	WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv6/esp6.o
	WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv6/xfrm6_tunnel.o
	WARNING: modpost: missing MODULE_DESCRIPTION() in net/ipv6/tunnel6.o

This part5 of the patchset focus on the missing net/ module, which
are now warning free.

Here are all the MODULE_DESCRIPTION added:

 MODULE_DESCRIPTION("CAN Identifier comparison network helpers");
 MODULE_DESCRIPTION("DSA loopback fixed PHY library");
 MODULE_DESCRIPTION("IP-in-IPv6 tunnel driver");
 MODULE_DESCRIPTION("IP/IP protocol decoder library");
 MODULE_DESCRIPTION("IPv4 AH transformation library");
 MODULE_DESCRIPTION("IPv4 ESP transformation library");
 MODULE_DESCRIPTION("IPv4 GRE tunnels over IP library");
 MODULE_DESCRIPTION("IPv4 tunnel implementation library");
 MODULE_DESCRIPTION("IPv4 UDP tunnel driver");
 MODULE_DESCRIPTION("IPv4 XFRM tunnel driver");
 MODULE_DESCRIPTION("IPv4 XFRM tunnel library");
 MODULE_DESCRIPTION("IPv6 AH transformation helpers");
 MODULE_DESCRIPTION("IPv6 ESP transformation helpers");
 MODULE_DESCRIPTION("IPv6-in-IPv4 tunnel SIT driver");
 MODULE_DESCRIPTION("IPv6 Mobility driver");
 MODULE_DESCRIPTION("IPv6 over Low-Power Wireless Personal Area Network core module");
 MODULE_DESCRIPTION("IPv6 UDP tunnel driver");
 MODULE_DESCRIPTION("IPv6 XFRM tunnel driver");
 MODULE_DESCRIPTION("IP-VLAN based tap driver");
 MODULE_DESCRIPTION("Metadata comparison network helpers");
 MODULE_DESCRIPTION("Multi byte comparison network helpers");
 MODULE_DESCRIPTION("Multi-Protocol Over ATM (MPOA) driver");
 MODULE_DESCRIPTION("PF_KEY socket helpers");
 MODULE_DESCRIPTION("Simple packet data comparison network helpers");
 MODULE_DESCRIPTION("Textsearch comparison network helpers");
 MODULE_DESCRIPTION("U32 Key comparison network helpers");
 MODULE_DESCRIPTION("Virtual (secure) IP tunneling library");
 MODULE_DESCRIPTION("XFRM Algorithm interface");
 MODULE_DESCRIPTION("XFRM User interface");

Changelog:

v1:
 * https://lore.kernel.org/all/20240205101400.1480521-1-leitao@debian.org/

v2:
 * Remove the patch for the ieee802154 , since the fix is already in
   net-next. See discussion at:

Hi Breno,

I don't feel strongly about this,
but looking at NET_UDP_TUNNEL and NET_FOU in net/ipv4/Kconfig, maybe:

	IPv6 Foo over UDP tunnel driver

Likewise for the change to net/ipv4/udp_tunnel_core.c
in the following patch.


The above not withstanding, this looks good to me.

Hi Breno,

I wonder if it would be useful to mention Ematch somehow
in the module descriptions as that is the context in
which they operate.

Hi Breno,

I'm not sure, but perhaps something like "mock-up Ethernet switch"
is better than loopback.

I'm looking at NET_DSA_LOOP in drivers/net/dsa/Kconfig

That sounds like it as library for any code, but it's TC extended match.
