[S390] tape: deadlock on system work queue

2011-03-03T16:56:14Z

The 34xx and 3590 tape driver uses the system work queue to defer work from the interrupt function to process context, e.g. a medium sense after an unsolicited interrupt. The tape commands started by the work handler need to be asynchronous, otherwise a deadlock on the system work queue can occur. Signed-off-by: Martin Schwidefsky

[S390] keyboard: integer underflow bug

2011-03-03T16:56:14Z

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. Cc: Signed-off-by: Dan Carpenter Signed-off-by: Martin Schwidefsky

[S390] xpram: remove __initdata attribute from module parameters

2011-03-03T16:56:14Z

The module parameter 'devs' and 'sizes' are marked as __initdata. The memory for the parameters are freed after module_init completed. This can lead to kernel crashes in param_free_charp. Remove the __initdata attribute to fix the problem. Signed-off-by: Martin Schwidefsky

[S390] dasd: correct device table

2011-02-17T12:13:58Z

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

s390: Fix possibly wrong size in strncmp (smsgiucv)

2011-02-02T23:00:02Z

This error was reported by cppcheck: drivers/s390/net/smsgiucv.c:63: error: Using sizeof for array given as function argument returns the size of pointer. Although there is no runtime problem as long as sizeof(u8 *) == 8, this misleading code should get fixed. Signed-off-by: Stefan Weil Signed-off-by: Frank Blaschka Signed-off-by: David S. Miller

s390: Fix wrong size in memcmp (netiucv)

2011-02-02T23:00:02Z

This error was reported by cppcheck: drivers/s390/net/netiucv.c:568: error: Using sizeof for array given as function argument returns the size of pointer. sizeof(ipuser) did not result in 16 (as many programmers would have expected) but sizeof(u8 *), so it is 4 or 8, too small here.

qeth: allow OSA CHPARM change in suspend state

2011-02-02T23:00:01Z

For OSA the CHPARM-definition determines the number of available outbound queues. A CHPARM-change may occur while a Linux system with probed OSA device is in suspend state. This patch enables proper resuming of an OSA device in this case. Signed-off-by: Ursula braun Signed-off-by: Frank Blaschka Signed-off-by: David S. Miller

qeth: allow HiperSockets framesize change in suspend

2011-02-02T23:00:00Z

For HiperSockets the framesize-definition determines the selected mtu-size and the size of the allocated qdio buffers. A framesize-change may occur while a Linux system with probed HiperSockets device is in suspend state. This patch enables proper resuming of a HiperSockets device in this case.

qeth: add more strict MTU checking

2011-02-02T23:00:00Z

HiperSockets and OSA hardware report a maximum MTU size. Add checking to reject larger MTUs than allowed by hardware. Signed-off-by: Frank Blaschka Signed-off-by: David S. Miller
