[PATCH iproute2-next v2 00/19] bridge: vlan: add global multicast options

[PATCH iproute2-next v2 00/19] bridge: vlan: add global multicast options

[Nikolay Aleksandrov]

From: Nikolay Aleksandrov <nikolay@nvidia.com>

Hi all,
This set adds support for vlan multicast options. The feature is
globally controlled by a new bridge option called mcast_vlan_snooping
which is added by patch 01. Then patches 2-5 add support for dumping
global vlan options and filtering on vlan id. Patch 06 adds support for
setting global vlan options and then patches 07-18 add all the new
global vlan options, finally patch 19 adds support for dumping vlan
multicast router ports. These options are identical in meaning, names and
functionality as the bridge-wide ones.

All the new vlan global commands are under the global keyword:
 $ bridge vlan global show [ vid VID dev DEVICE ]
 $ bridge vlan global set vid VID dev DEVICE ...

I've added command examples in each commit message. The patch-set is a
bit bigger but the global options follow the same pattern so I don't see
a point in breaking them. All man page descriptions have been taken from
the same current bridge-wide mcast options. The only additional iproute2
change which is left to do is the per-vlan mcast router control which
I'll send separately. Note to properly use this set you'll need the
updated kernel headers where mcast router was moved from a global option
to per-vlan/per-device one (changed uapi enum which was in net-next).

Example:
 # enable vlan mcast snooping globally
 $ ip link set dev bridge type bridge mcast_vlan_snooping 1
 # enable mcast querier on vlan 100
 $ bridge vlan global set dev bridge vid 100 mcast_querier 1
 # show vlan 100's global options
 $ bridge -s vlan global show vid 100
port              vlan-id
bridge            100
                    mcast_snooping 1 mcast_querier 1 mcast_igmp_version 2 mcast_mld_version 1 mcast_last_member_count 2 mcast_last_member_interval 100 mcast_startup_query_count 2 mcast_startup_query_interval 3125 mcast_membership_interval 26000 mcast_querier_interval 25500 mcast_query_interval 12500 mcast_query_response_interval 1000

A following kernel patch-set will add selftests which use these commands.

v2: all patches use strcmp instead of matches
    patches 02, 03 which prepare print_vlan_rtm for global show are new
    previous patch 02 is split in patches 02, 03 and 04
    patches 07-18 have their help msg alignment adjusted to fit in 100
    characters

Thanks,
 Nik

[PATCH iproute2-next v2 02/19] bridge: vlan: factor out vlan option printing

[Nikolay Aleksandrov]

From: Nikolay Aleksandrov <nikolay@nvidia.com>

Factor out the code which prints current per-vlan options from
print_vlan_rtm without any changes, later we'll filter based on the vlan
attribute and add support for global vlan option printing.

[PATCH iproute2-next v2 03/19] bridge: vlan: skip unknown attributes when printing options

[Nikolay Aleksandrov]

From: Nikolay Aleksandrov <nikolay@nvidia.com>

Skip unknown attributes when printing vlan options in print_vlan_rtm.
Make sure print_vlan_opts doesn't accept attributes it doesn't understand.
Currently we print only one type, later global vlan options support will
be added.

[PATCH iproute2-next v2 04/19] bridge: vlan: add support to show global vlan options

[Nikolay Aleksandrov]

From: Nikolay Aleksandrov <nikolay@nvidia.com>

Add support for new bridge vlan command grouping called global which
operates on global options. The first command it supports is "show".
To do that we update print_vlan_rtm to recognize the global vlan options
attribute and parse it properly.
Man page and help are also updated with the new command.

Syntax is: $ bridge vlan global show [ vid VID ] [ dev DEV ]

[PATCH iproute2-next v2 05/19] bridge: vlan: add support for vlan filtering when dumping options

[Nikolay Aleksandrov]

From: Nikolay Aleksandrov <nikolay@nvidia.com>

In order to allow vlan filtering when dumping options we need to move
all print operations into the option dumping functions and add the
filtering after we've parsed the nested attributes so we can extract the
start and end vlan ids.

[PATCH iproute2-next v2 06/19] bridge: vlan: add support to set global vlan options

[Nikolay Aleksandrov]

From: Nikolay Aleksandrov <nikolay@nvidia.com>

Add support to change global vlan options via a new vlan global
set subcommand similar to the current vlan set subcommand. The man page
and help are updated accordingly. The command works only with bridge
devices. It doesn't support any options yet.

How did you redo this patch set where 06 uses strcmp for the help line
and yet patches 7-17 all have matches?

Fixed those up given where we are with 5.14 cycle and applied to
iproute2-next.

[PATCH iproute2-next v2 15/19] bridge: vlan: add global mcast_query_interval option

[Nikolay Aleksandrov]

From: Nikolay Aleksandrov <nikolay@nvidia.com>

Add control and dump support for the global mcast_query_interval
option which controls the interval between queries sent by the bridge
after the end of the startup phase. To be consistent with the same
bridge-wide option the value is reported with USER_HZ granularity and
the same granularity is expected when setting it.

[PATCH iproute2-next v2 19/19] bridge: vlan: add support for dumping router ports

[Nikolay Aleksandrov]

From: Nikolay Aleksandrov <nikolay@nvidia.com>

Add dump support for vlan multicast router ports and their details if
requested. If details are requested we print 1 entry per line, otherwise
we print all router ports on a single line similar to how mdb prints
them.

Looks like:
$ bridge vlan global show vid 100
 port              vlan-id
 bridge            100
                     mcast_snooping 1 mcast_querier 0 mcast_igmp_version 2 mcast_mld_version 1 mcast_last_member_count 2 mcast_last_member_interval 100 mcast_startup_query_count 2 mcast_startup_query_interval 3125 mcast_membership_interval 26000 mcast_querier_interval 25500 mcast_query_interval 12500 mcast_query_response_interval 1000
                     router ports: ens20 ens16

Looks like (with -s):
 $ bridge -s vlan global show vid 100
 port              vlan-id
 bridge            100
                     mcast_snooping 1 mcast_querier 0 mcast_igmp_version 2 mcast_mld_version 1 mcast_last_member_count 2 mcast_last_member_interval 100 mcast_startup_query_count 2 mcast_startup_query_interval 3125 mcast_membership_interval 26000 mcast_querier_interval 25500 mcast_query_interval 12500 mcast_query_response_interval 1000
                     router ports: ens20   187.57 temp
                                   ens16   118.27 temp
