* | bonding: allow arp_ip_targets on separate vlans to use arp validationAndy Gospodarek2010-01-04
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows a bond device to specify an arp_ip_target as a host that is not on the same vlan as the base bond device and still use arp validation.

If those match, then the Partner's synchronization state is set to true. The current 802.3ad implementation is performing these steps out of order; first, the synchronization check is done, then the paramters are checked to see if they match (the synch check being done against a match check of a prior LACPDU). This causes delays in establishing aggregators in some circumstances. This patch modifies the 802.3ad code to call __choose_matched, the function that does the "match" comparisions, as the first step of __record_pdu, instead of immediately afterwards. This new behavior is in compliance with the language of the standard. Some additional commentary relating to code vs. standard is also added. Reported by Martin Patterson <martin@gear6.com> who also supplied the logic of the fix and verified the patch. Signed-off-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In mii monitor mode, bond_check_dev_link() calls the the ioctl handler of slave devices. It stores the ndo_do_ioctl function pointer to a static (!) ioctl variable and later uses it to call the handler with the IOCTL macro. If another thread executes bond_check_dev_link() at the same time (even with a different bond, which none of the locks prevent), a race condition occurs. If the two racing slaves have different drivers, this may result in one driver's ioctl handler being called with a pointer to a net_device controlled with a different driver, resulting in unpredictable breakage. Unless I am overlooking something, the "static" must be a copy'n'paste error (?). Signed-off-by: Jiri Bohac <jbohac@suse.cz> Signed-off-by: David S. Miller <davem@davemloft.net>

* bonding: remap muticast addresses without using dev_close() and dev_open()Moni Shoua2009-09-15
| | | | | | | | | | | | | | | | | | | | This patch fixes commit e36b9d16c6a6d0f59803b3ef04ff3c22c3844c10. The approach there is to call dev_close()/dev_open() whenever the device type is changed in order to remap the device IP multicast addresses to HW multicast addresses. This approach suffers from 2 drawbacks: *. It assumes tha the device is UP when calling dev_close(), or otherwise dev_close() has no affect. It is worth to mention that initscripts (Redhat) and sysconfig (Suse) doesn't act the same in this matter. *. dev_close() has other side affects, like deleting entries from the routing table, which might be unnecessary. The fix here is to directly remap the IP multicast addresses to HW multicast addresses for a bonding device that changes its type, and nothing else.

| * bonding: clean muticast addresses when device changes typeMoni Shoua2009-07-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bonding device forbids slave device of different types under the same master. However, it is possible for a bonding master to change type during its lifetime. This can be either from ARPHRD_ETHER to ARPHRD_INFINIBAND or the other way arround. The change of type requires device level multicast address cleanup because device level multicast addresses depend on the device type. The patch adds a call to dev_close() before the bonding master changes type and dev_open() just after that. In the example below I enslaved an IPoIB device (ib0) under bond0. Since each bonding master starts as device of type ARPHRD_ETHER by default, a change of type occurs when ib0 is enslaved. This is how /proc/net/dev_mcast looks like without the patch 5 bond0 1 0 00ffffffff12601bffff000000000001ff96ca05 5 bond0 1 0 01005e000116 5 bond0 1 0 01005e7ffffd 5 bond0 1 0 01005e000001 5 bond0 1 0 333300000001 6 ib0 1 0 00ffffffff12601bffff000000000001ff96ca05 6 ib0 1 0 333300000001 6 ib0 1 0 01005e000001 6 ib0 1 0 01005e7ffffd 6 ib0 1 0 01005e000116 6 ib0 1 0 00ffffffff12401bffff00000000000000000001 6 ib0 1 0 00ffffffff12601bffff00000000000000000001 and this is how it looks like after the patch. 5 bond0 1 0 00ffffffff12601bffff000000000001ff96ca05 5 bond0 1 0 00ffffffff12601bffff00000000000000000001 5 bond0 1 0 00ffffffff12401bffff0000000000000ffffffd 5 bond0 1 0 00ffffffff12401bffff00000000000000000116 5 bond0 1 0 00ffffffff12401bffff00000000000000000001 6 ib0 1 0 00ffffffff12601bffff000000000001ff96ca05 6 ib0 1 0 00ffffffff12401bffff00000000000000000116 6 ib0 1 0 00ffffffff12401bffff0000000000000ffffffd 6 ib0 2 0 00ffffffff12401bffff00000000000000000001 6 ib0 2 0 00ffffffff12601bffff00000000000000000001 Signed-off-by: Moni Shoua <monis@voltaire.com> Signed-off-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: David S.

[ J adds: AD_STATE_LACP_ACTIVITY is a value defined by the standard, and should be set here in accordance with 802.3ad 43.4.12; AD_SHORT_TIMEOUT is a constant specific to the Linux 802.3ad implementation that happens to have the same value ] The semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ struct port_params p; @@ * p.port_state |= AD_SHORT_TIMEOUT // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: David S.

* | net: convert remaining non-symbolic return values in ndo_start_xmit() functionsPatrick McHardy2009-07-05
|/ | | | | | | | | | | | This patch converts the remaining occurences of raw return values to their symbolic counterparts in ndo_start_xmit() functions that were missed by the previous automatic conversion. Additionally code that assumed the symbolic value of NETDEV_TX_OK to be zero is changed to explicitly use NETDEV_TX_OK. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.
