These patches contain the following linux kernel bug fixes:

Description:

lcs: System hang, when registering of multicast addresses fails.

Symptom:

Endless loop, when setting lcs device online and then registering of multicast addresses fails.

Problem:

Used list_for_each_entry() instead of list_for_each_safe() in a case where elements are removed from the list.
This is not allowed with list_for_each_entry.

Solution:

Replace list_for_each_entry() with list_for_each_safe().

Problem-ID:

14818

Description:

qeth: Layer2: VLAN unicast packets malformed.

Symptom:

Using qeth ethernet device in Layer 2 mode VLAN unicast packets will not arrive at vlan network device.

Problem:

The protocol is not set properly and VLAN tag is not correct either.

Solution:

First strip out the ethernet header and then set skb's protocol = encapsulated protocol.

Problem-ID:

15190

Description:

qeth: do not allow layer 2 mode in case of Hipersockets devices.

Symptom:

Hipersockets device initialization fails when layer 2 option is set.

Problem:

Using layer2 chandev option in conjunction with Hipersockets devices is not allowed but qeth tries to initialize Hipersockets devices in layer 2 mode as well.

Solution:

Turn off layer2 option in case of Hipersockets and go on with initializating Hipersockets in non-layer2 mode.

Problem-ID:

15194

Description:

s390dbf: Use more specific permissions for procfiles.

Symptom:

All s390dbf procfiles have same permissions.

Problem:

Permissions should be more specific. E.g read only views should have read permission, write only views should have write permission.

Solution:

Set correct permissions.

Problem-ID:

14372

Description:

scsi: LVM is unable to re-enable a path after a cable pull.

Symptom:

If FC cable is pulled for 10 minutes LVM is unable to re-enable the paths for all LUNs.

Problem:

After a timeout SCSI device is set offline which makes its recovery impossible.

Solution:

Introduce a new flag in SCSI host structure which, when set on, lets SCSI devices on this host never being set offline.

Problem-ID:

12614

Description:

z90crypt: Writing to /proc/driver/z90crypt can cause a kernel Oops.

Symptom:

Kernel Oops.

Problem:

Incorrect bounds checking on procfs write routine.

Solution:

Replace my string scanner with strstr and better error checking.

Problem-ID:

15058

Description:

zfcp: Increase retrying of exchange config data requests up to 2 minutes.

Symptom:

If exchange config data FSF request has being sent to FCP adapter while it is initializing a connection, exchange config data could not proceed even after retries.

Problem:

In case FSF request comes back with protocol status HOST_CONNECTION_INITIALIZING zfcp module makes 6 retries sleeping for 0.5 second between each retry.

Solution:

In case of HOST_CONNECTION_INITIALIZING let make a first retry in 1 second, then double the sleep time for each following retry until recovery exceeds 2 minutes.

Problem-ID:

15083
