These patches contain the following linux kernel bug fixes:

Description:

cio: Remove debug code.

Symptom:

None observable.

Problem:

Superfluous code written for debugging a problem.

Solution:

Remove the code.

Problem-ID:

-

Description:

ctcmpc: Enable further dynamic debug output.

Symptom:

Debug information is not written.

Problem:

More debug information should be written.

Solution:

Change level of debug that can be obtained without a recompile of module and remove white spaces.

Problem-ID:

-

Description:

dcssblk: Fixed call for bio_io_error in case of I/O errors.

Symptom:

System hangs, process accessing the block device stays in D state.

Problem:

Incorrect length supplied on call of bio_io_error.

Solution:

Call with full length of bio.

Problem-ID:

14821

Description:

dcssblk: Disallow write requests to read only dcss block devices.

Symptom:

Kernel oops when mounting, after explicit modification of the read-only attribute for the block device.

Problem:

No verification of the data direction.

Solution:

Add verification, issue a warning, and post I/O error on illegal requests.

Problem-ID:

14819

Description:

kernel: 3270 error handling.

Symptom:

The 3270 driver crashes if a control-c is sent while the device is in the online process.

Problem:

Errors in the 3270 device startup sequence are not handled correctly.

Solution:

Check for errors in the startup sequence and issue a halt_io if the startup sequence has been interrupted.

Problem-ID:

14817

Description:

kernel: Any guest can send SMSG messages to cmm.

Symptom:

SMSG messages sent by any guest can trigger cmm actions.

Problem:

An arbitrary guest must not be allowed to trigger cmm actions. Only one specific guest (namely the one that serves a resource monitor) may send cmm messages.

Solution:

Add a parameter that allows to specify the guest that may send SMSG messages to cmm.

Problem-ID:

14816

Description:

kernel: diag10 on storage segments behind the first one.

Symptom:

Addressing exception using cmm with more than one storage segment.

Problem:

z/VM supports diag10 only for the first defined storage segment. If the collaborative memory management is used with a storage configuration with more than one segment this crashes the kernel.

Solution:

Add a fixup section to the diag10 inline assembly to catch the addressing exception.

Problem-ID:

14815

Description:

kernel: Static per-cpu variables and gcc 3.4.

Symptom:

ipv6.ko needs unknown symbol per_cpu____icmppv6_socket.

Problem:

gcc 3.4 removes statically defined per-cpu variables because all accesses to per-cpu variables are done by hidden relocations. gcc 3.4 and later compilers remove unused static variables.

Solution:

Pass a reference to the inline assemblies that do the hidden relocations to make gcc aware of the fact that the static per-cpu variables are not unused.

Problem-ID:

14814

Description:

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

Symptom:

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

Problem:

Used list_for_each_entry() instead of list_for_each_entry_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_entry_safe().

Problem-ID:

14818

Description:

qeth, claw: Several fixes for qeth and claw.

Symptom:

Claw could not be loaded, DHCP with Layer 2 does not work properly.

Problem:

Missing entry for channeltype claw in cu3088. Bug in Layer 2 qeth code.

Solution:

Added entry for channeltype claw in cu3088. Fix Layer 2 code.

Problem-ID:

-

Description:

zfcp: Wrong handling of FSF states PORT_BOXED/LUN_BOXED.

Symptom:

Recovery of ports and units after receiving unsolicited status "ACT updated" does not work.

Problem:

FSF states PORT_BOXED/LUN_BOXED are not handled properly.

Solution:

Handle FSF states PORT_BOXED/LUN_BOXED same as ACCESS_DENIED.

Problem-ID:

-

Description:

zfcp: Incorrect memset.

Symptom:

Sg-list not correctly initialized.

Problem:

Parameters for memset were interchanged.

Solution:

Correct parameters for memset.

Problem-ID:

-
