bonding: get netdev_rx_handler_unregister out of locks

2013-04-05T16:26:29+00:00

[ Upstream commit fcd99434fb5c137274d2e15dd2a6a7455f0f29ff ]

Now that netdev_rx_handler_unregister contains synchronize_net(), we need
to call it outside of bond->lock, cause it might sleep. Also, remove the
already unneded synchronize_net().

bonding: fix disabling of arp_interval and miimon

2013-04-05T16:26:17+00:00

[ Upstream commit 1bc7db16782c2a581fb4d53ca853631050f31611 ]

Currently if either arp_interval or miimon is disabled, they both get
disabled, and upon disabling they get executed once more which is not
the proper behaviour. Also when doing a no-op and disabling an already
disabled one, the other again gets disabled.
Also fix the error messages with the proper valid ranges, and a small
typo fix in the up delay error message (outputting "down delay", instead
of "up delay").

bonding: remove already created master sysfs link on failure

2013-04-05T16:26:17+00:00

[ Upstream commit 9fe16b78ee17579cb4f333534cf7043e94c67024 ]

If slave sysfs symlink failes to be created - we end up without removing
the master sysfs symlink. Remove it in case of failure.

bonding: don't call update_speed_duplex() under spinlocks

2013-03-28T19:17:07+00:00

[ Upstream commit 876254ae2758d50dcb08c7bd00caf6a806571178 ]

bond_update_speed_duplex() might sleep while calling underlying slave's
routines. Move it out of atomic context in bond_enslave() and remove it
from bond_miimon_commit() - it was introduced by commit 546add79, however
when the slave interfaces go up/change state it's their responsibility to
fire NETDEV_UP/NETDEV_CHANGE events so that bonding can properly update
their speed.

I've tested it on all combinations of ifup/ifdown, autoneg/speed/duplex
changes, remote-controlled and local, on (not) MII-based cards. All changes
are visible.

bonding: fire NETDEV_RELEASE event only on 0 slaves

2013-03-20T20:10:58+00:00

[ Upstream commit 80028ea1c0afc24d4ddeb8dd2a9992fff03616ca ]

Currently, if we set up netconsole over bonding and release a slave,
netconsole will stop logging on the whole bonding device. Change the
behavior to stop the netconsole only when the last slave is released.

bonding: unset primary slave via sysfs

2013-01-29T20:43:35+00:00

When bonding module is loaded with primary parameter and one decides to unset
primary slave using sysfs these settings are not preserved during bond device
restart. Primary slave is only unset once and it's not remembered in
bond->params structure. Below is example of recreation.

 grep OPTS /etc/sysconfig/network-scripts/ifcfg-bond0
BONDING_OPTS="mode=active-backup miimon=100 primary=eth01"
 grep "Primary Slave" /proc/net/bonding/bond0
Primary Slave: eth01 (primary_reselect always)

 echo "" > /sys/class/net/bond0/bonding/primary
 grep "Primary Slave" /proc/net/bonding/bond0
Primary Slave: None

 sed -i -e 's/primary=eth01//' /etc/sysconfig/network-scripts/ifcfg-bond0
 grep OPTS /etc/sysconfig/network-scripts/ifcfg-bond
BONDING_OPTS="mode=active-backup miimon=100 "
 ifdown bond0 && ifup bond0

without patch:
 grep "Primary Slave" /proc/net/bonding/bond0
Primary Slave: eth01 (primary_reselect always)

with patch:
 grep "Primary Slave" /proc/net/bonding/bond0
Primary Slave: None

bonding: do not cancel works in bond_uninit()

2012-12-14T18:14:07+00:00

Bonding initializes these works in bond_open() and cancels in bond_close(),
thus in bond_uninit() they are already canceled but may be unitialized yet.

bonding: Fix check for ethtool get_link operation support

2012-12-07T19:35:35+00:00

Since commit 2c60db037034 ('net: provide a default dev->ethtool_ops')
all devices have a non-null ethtool_ops.  Test only
dev->ethtool_ops->get_link in both places where we care.
