309b905deee595619cc38719f48d63d57b8bff3d - ipv6: convert CONFIG_IPV6 to built-in only and clean up Kconfigs

Wed, 25 Mar 2026 13:08:42 +0100

ipv6: convert CONFIG_IPV6 to built-in only and clean up KconfigsMaintaining a modular IPv6 stack offers image size savings for specificsetups, this benefit is outweighed by the architectural burden itimposes on the subsystems on implementation and maintenance. Therefore,drop it.Change CONFIG_IPV6 from tristate to bool. Remove all Kconfigdependencies across the tree that explicitly checked for IPV6=m. Inaddition, remove MODULE_DESCRIPTION(), MODULE_ALIAS(), MODULE_AUTHOR()and MODULE_LICENSE().This is also replacing module_init() by device_initcall(). It is notpossible to use fs_initcall() as IPv4 does because that creates a racecondition on IPv6 addrconf.Finally, modify the default configs from CONFIG_IPV6=m to CONFIG_IPV6=yexcept for m68k as according to the bloat-o-meter the image isincreasing by 330KB~ and that isn't acceptable. Instead, disable IPv6 onthis architecture by default. This is aligned with m68k RAM requirementsand recommendations [1].[1] http://www.linux-m68k.org/faq/ram.htmlSigned-off-by: Fernando Fernandez Mancera Tested-by: Ricardo B.

Sat, 13 Jun 2020 18:50:22 +0200

treewide: replace '---help---' in Kconfig files with 'help'Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over'---help---'"), the number of '---help---' has been graduallydecreasing, but there are still more than 2400 instances.This commit finishes the conversion. While I touched the lines,I also fixed the indentation.There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---'In order to convert all of them to 1 tab + 'help', I ran thefollowing commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'Signed-off-by: Masahiro Yamada List of files: /linux/net/bridge/Kconfig

bridge: Add vlan filtering infrastructureAdds an optional infrustructure component to bridge that would allownative vlan filtering in the bridge. Each bridge port (as wellas the bridge device) now get a VLAN bitmap. Each bit in the bitmapis associated with a vlan id. This way if the bit corresponding tothe vid is set in the bitmap that the packet with vid is allowed toenter and exit the port.Write access the bitmap is protected by RTNL and read accessprotected by RCU.Vlan functionality is disabled by default.Signed-off-by: Vlad Yasevich Signed-off-by: David S.

Sat, 27 Feb 2010 20:41:45 +0100

bridge: Add core IGMP snooping supportThis patch adds the core functionality of IGMP snooping supportwithout actually hooking it up. So this patch should be a no-opas far as the bridge's external behaviour is concerned.All the new code and data is controlled by the Kconfig optionBRIDGE_IGMP_SNOOPING. A run-time toggle is also available.The multicast switching is done using an hash table that islockless on the read-side through RCU. On the write-side thenew multicast_lock is used for all operations. The hash tablesupports dynamic growth/rehashing.The hash table will be rehashed if any chain length exceeds apreset limit. If rehashing does not reduce the maximum chainlength then snooping will be disabled.These features may be added in future (in no particular order):* IGMPv3 source support* Non-querier router detection* IPv6Signed-off-by: Herbert Xu Signed-off-by: David S.

[BRIDGE]: use llc for receiving STP packetsUse LLC for the receive path of Spanning Tree Protocol packets.This allows link local multicast packets to be received byother protocols (if they care), and uses the existing LLCcode to get STP packets back into bridge code.The bridge multicast address is also checked, so bridges usingother link local multicast addresses are ignored. This allowsfor use of different multicast addresses to define separate STPdomains.Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller List of files: /linux/net/bridge/Kconfig

[NET]: move config options out to individual protocolsMove the protocol specific config options out to the specific protocols.With this change net/Kconfig now starts to become readable and serve as agood basis for further re-structuring.The menu structure is left almost intact, except that indention isfixed in most cases. Most visible are the INET changes where several"depends on INET" are replaced with a single ifdef INET / endif pair.Several new files were created to accomplish this change - they aresmall but serve the purpose that config options are now distributedout where they belongs.Signed-off-by: Sam Ravnborg Signed-off-by: David S.
