These patches contain the following linux kernel bug fixes:
Description:
cio: Restart SenseID after pending status.
Symptom:
After attach, tapes appear to be 'boxed'.
Problem:
The check whether to retry SenseID after an unsolicited
interrupt was too stringent.
Solution:
Fix check for restarting.
Problem-ID:
11914
Description:
kernel: User process executing in wrong address-space mode.
Symptom:
Kernel oops.
Problem:
A space switching instruction in a user program causes a
home space switch event exception. The stored old psw
already contains the new address-space control which is
not reset to the home space mode.
Solution:
Reset the address-space control to home space mode for
home space switch event exceptions.
Problem-ID:
11661
Description:
qeth: IPv6 over VLAN fails.
Symptom:
IPv6 over VLAN interfaces does not work.
Problem:
The 4 byte VLAN tag (0x8100<VLAN-ID>) is not aligned
properly in outbound packets.
Solution:
Fix alignment of VLAN tag.
Problem-ID:
8619
Description:
qeth: Wrong alignment of VLAN tag when using fake_ll.
Symptom:
When fake_ll is used the 4 bytes VLAN tag is mis-placed in
the header of received packets. Tools such as tcpdump display
wrong data.
Problem:
VLAN tag was placed at the wrong position when fake_ll is used.
Solution:
Fix position of VLAN tag in conjunction with fake_ll.
Problem-ID:
11059
Description:
zfcp: Insufficient debugging information in /var/log/messages
for 'LUN sharing violation'.
Symptom:
If a LUN is already in use by another LPAR zfcp does not log
the CCS ID.
Problem:
If a LUN is already in use by another LPAR zfcp logs only
an LPAR number inside CSS, but not the ID of the CSS.
Solution:
Log LPAR number and CSS ID.
Problem-ID:
11576
Description:
zfcp: Kernel stack frame for zfcp_cfdc_dev_ioctl() is too big.
Symptom:
Calls to the CFDC interface of the ZFCP module use too much
memory on kernel stack, which may result in kernel crash.
Problem:
Frame size of zfcp_cfdc_dev_ioctl() function in ZFCP module
is 424 bytes.
Solution:
Use pointer instead of structure for variable sense_data in
zfcp_cfdc_dev_ioctl() to save 284 bytes of stack space.
Problem-ID:
11518
