linux-2.4.21-s390-31-june2003-patches.tar.gz / MD5 ... per-problem-patches, recommended (2005-12-22)

These patches contain the following linux kernel bug fixes:

qeth: Connectivity lost after Layer 2 device recovery.
Recovery of non-guestLAN Layer 2 device failed which results in connectivity lost.
Recovery of non-guestLAN Layer 2 device failed due to trying to register the real MAC address we got from the READ_MAC adapter parameters command.
We have to keep the "old" MAC address when we process the reply of a READ_MAC, means ignore the new one.
qeth: NULL pointer de-reference with bonding and VLAN device.
Starting a VLAN device with ifup, which is configured on top of a bonding device bond0 results in NULL pointer de-reference in qeth code.
qeth_verify_vlan_dev checks if net_device is a real device or a VLAN device. If a VLAN device is found, we are taking the card's address from the priv pointer. This is only correct for VLAN devices which are configured on top of OSA devices.
If VLAN device is configured on top of a bonding device the priv pointer contains the address of the bonding structure.
Check, if priv pointer is equal to card's address, once the VLAN device is found in the VLAN group array of a qeth_card.

Everybody should apply this patch.
