This patchset is used to support sending rntl info to user in some places,
and ensure that whenever those attributes change internally or from sysfs,
that a netlink notification is sent out to listeners.
It also make some adjustment in bridge sysfs so that we can implement this
easily.
I've done some tests on this patchset, like:
[br_sysfs]
1. change all the attribute values of br or brif:
$ echo $value > /sys/class/net/br0/bridge/{*}
$ echo $value > /sys/class/net/br0/brif/eth1/{*}
2. meanwhile, on another terminal to observe the msg:
$ bridge monitor
[br_ioctl]
1. in bridge-utils package, do some changes in br_set, let brctl command
use ioctl to set attribute:
if ((ret = set_sysfs(path, value)) < 0) { -->
if (1) {
$ brctl set*
2. meanwhile, on another terminal to observe the msg:
$ bridge monitor
This test covers all the attributes that brctl and sysfs support to set.
Xin Long (6):
bridge: add rtnl_lock in fdb_flush in br_sysfs_br.c
bridge: simplify the forward_delay_store by calling store_bridge_parm
bridge: simplify the stp_state_store by calling store_bridge_parm
bridge: a netlink notification should be sent when those attributes
are changed by br_sysfs_br
bridge: a netlink notification should be sent when those attributes
are changed by br_sysfs_if
bridge: a netlink notification should be sent when those attributes
are changed by ioctl
