[S390] ccwgroup: move attributes to attribute group

2012-08-17T19:35:36Z

commit dbdf1afcaaabe83dea15a3cb9b9013e73ae3b1ad upstream. Put sysfs attributes of ccwgroup devices in an attribute group to ensure that these attributes are actually present when userspace is notified via uevents.

dasd: correct device table

2012-03-14T14:57:26Z

commit 5da24b7627ff821e154a3aaecd5d60e1d8e228a5 upstream. The 3880 storage control unit supports a 3380 device type, but not a 3390 device type. Reported-by: Stephen Powell Signed-off-by: Stefan Haberland Signed-off-by: Martin Schwidefsky Signed-off-by: Paul Gortmaker

keyboard: integer underflow bug

2011-06-26T16:46:56Z

commit b652277b09d3d030cb074cc6a98ba80b34244c03 upstream. The "ct" variable should be an unsigned int. Both struct kbdiacrs ->kb_cnt and struct kbd_data ->accent_table_size are unsigned ints. Making it signed causes a problem in KBDIACRUC because the user could set the signed bit and cause a buffer overflow.

[S390] dasd: fix race between tasklet and dasd_sleep_on

2010-05-12T07:32:26Z

The various dasd_sleep_on functions use a global wait queue when waiting for a cqr. The wait condition checks the status and devlist fields of the cqr to determine if it is safe to continue. This evaluation may return true, although the tasklet has not finished processing of the cqr and the callback function has not been called yet. When the callback is finally called, the data in the cqr may already be invalid. The sleep_on wait condition needs a safe way to determine if the tasklet has finished processing. Use the callback_data field of the cqr to store a token, which is set by the callback function itself.

[S390] zcore: Fix reipl device detection

2010-04-22T15:17:19Z

The reipl device information is passed from the kernel to zfcpdump using a pointer in the lowcore (0xe00) that points to the reipl information Currently if that pointer is not zero, we copy the reipl information. If the pointer is not initialized and points outside the accessible memory, it can happen that the memory copy fails. In that case we currently stop the initialization of zcore which leads to a failing kernel dump. The correct behavior is to disable the reipl after dump and continue with zcore intialization.

[S390] cio: use exception-save stsch

2010-04-22T15:17:19Z

Using stsch on schids with ssid != 0 can lead to an operand exception. Use stsch_err to handle potential exceptions if we fail to reenable mss after hibernation. Cc: Signed-off-by: Sebastian Ott Signed-off-by: Martin Schwidefsky

[S390] add hook to reenable mss after hibernation

2010-04-22T15:17:19Z

Reenable multiple subchannel sets after hibernation, prior to the device callbacks. Cc: Signed-off-by: Sebastian Ott Signed-off-by: Martin Schwidefsky

[S390] cio: allow enable_facility from outside init functions

2010-04-22T15:17:19Z

Prepare chsc_enable_facility to be used from outside init functions. Use static memory for the chsc call and protect its access by a spinlock (although there is no concurrent usage). Cc: Signed-off-by: Sebastian Ott Signed-off-by: Martin Schwidefsky

[S390] dasd: fix endless loop in erp

2010-04-22T15:17:19Z

If not enough memory is available to build a new erp request it ended up in an endless loop trying to build erp requests. Fixed the loop to proceed the next request instead. Signed-off-by: Stefan Haberland Signed-off-by: Martin Schwidefsky
