qeth: avoid buffer overflow in snmp ioctl

2014-05-19T05:54:34+00:00

commit 6fb392b1a63ae36c31f62bc3fc8630b49d602b62 upstream Check user-defined length in snmp ioctl request and allow request only if it fits into a qeth command buffer.

compat: fix compile breakage on s390

2012-03-04T17:49:22+00:00

commit 048cd4e51d24ebf7f3552226d03c769d6ad91658 upstream. The new is_compat_task() define for the !COMPAT case in include/linux/compat.h conflicts with a similar define in arch/s390/include/asm/compat.h. This is the minimal patch which fixes the build issues. Signed-off-by: Heiko Carstens Signed-off-by: Linus Torvalds Cc: Jonathan Nieder Signed-off-by: Greg Kroah-Hartman

2011-11-07T20:32:33+00:00

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

2011-05-09T22:54:50+00:00

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 Cc: Stephen Powell Cc: Jonathan Nieder Cc: Bastian Blank

keyboard: integer underflow bug

2011-03-14T21:29:53+00:00

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.

nohz: Introduce arch_needs_cpu

2010-08-13T20:20:13+00:00

commit 3c5d92a0cfb5103c0d5ab74d4ae6373d3af38148 upstream. Allow the architecture to request a normal jiffy tick when the system goes idle and tick_nohz_stop_sched_tick is called . On s390 the hook is used to prevent the system going fully idle if there has been an interrupt other than a clock comparator interrupt since the last wakeup. On s390 the HiperSockets response time for 1 connection ping-pong goes down from 42 to 34 microseconds. The CPU cost decreases by 27%.

commit b8ed5dd54895647c2690575aad6f07748c2c618a upstream. Remove strings from s390 debugfeature entries that could lead to a crash when the data is read from dbf because the strings do not exist any more.

zcrypt: Do not remove coprocessor for error 8/72

2010-02-09T12:50:44+00:00

commit 19b123ebacacdce5e75045bfe82122b01c821a5b upstream. In a case where the number of the input data is bigger than the modulus of the key, the coprocessor adapters will report an 8/72 error. This case is not caught yet, thus the adapter will be taken offline. To prevent this, we return an -EINVAL instead.
